And act according to the requirements of eight honors and eight disgraces, write them into regular ideological newspapers in time, and actively move closer to the party organization and fight for it. In the work, I constantly learn new technologies and processes, constantly enrich myself, and constantly improve my technical level to guide my work.
Carry forward the spirit of teamwork in the work and strive to complete the production tasks in the workshop.
1, in my usual work, I should first do my daily work well. I have both division of labor and cooperation with other technicians in the workshop, insist on regular work exchanges with other technicians, fully carry forward democracy, put an end to arbitrariness, unify my thoughts and steps, and successfully complete various maintenance tasks in the workshop.
2, according to the spirit of the industry, I cooperate with other technicians to do a good job, and report the problems encountered in the work to the workshop leaders in time, and arrange relevant personnel to solve them. Do a good job in preparation for the maintenance period, work hard and adjust all the work in advance to ensure the success of the task and the quality of maintenance.

Summarize the production situation of the workshop once a month and submit it to the technical department in time; Summarize the consumption of main materials in the workshop and submit them to the planning department in time. Do a good job in statistics and technical analysis, analyze the difficulties in workshop production and take corrective measures, and write a report on corrective measures.
Carefully arrange the training of employees to improve their theoretical level and operational level.
Doing a good job in employee training is the long-term unremitting work of our workshop. For this reason, our workshop has specially formulated a training system, requiring each team to organize employee training at least twice a month and carry out various forms of employee training. For new workers who change jobs, a master-apprentice contract is required, and they can work independently only after passing the examination of technicians. Always sound the alarm for employees and enhance their sense of responsibility at work.
Looking back on my work in the past year, although I tried my best, my work performance is still far from the requirements of the leaders. In the new year, I will work harder and conscientiously complete the tasks assigned by the leaders.

In 20____, I graduated from _ _ _ College, majoring in internal combustion engine manufacturing and maintenance. I just graduated from college and came to work in the company. During my work, I gradually mastered the basic requirements of vehicle maintenance through serious internship and diligent practice. Under the careful care and guidance of leaders and colleagues, I have made some progress in all aspects through my unremitting efforts. Now I will report my work. Please point out the shortcomings!
First, there are roads in Shushan, and the sea of skills is boundless.
When I arrived at the maintenance and manufacturing center, I knew that as a skilled worker, if I didn't understand the drawings, the principle of equipment and the structure of vehicles, I would not only be embarrassed, but also be a qualified worker. I overcome the unfavorable factors such as lack of practical experience, and strive to "refuel" myself with a "bull's strength" of not stopping until I reach my goal.
I sorted out some useful technical books, deeply studied technical theories such as vehicle structure and mechanical foundation, and applied what I learned to production practice to continuously improve my professional skills. Sometimes, in order to find out the ins and outs of an accessory, I will study the technical data all night, and I will never give up until I understand it; Sometimes, what I can't finish in the workshop, I take it back to the dormitory for research. Over time, my dormitory became my "research institute".
Many things happen. After studying hard, I have made rapid progress, but I am not complacent at all. I know that although I am a college student, many masters in the maintenance and manufacturing center have rich experience and are examples for me to learn. On the road of learning professional technology, there is no room for any falsehood and slack. I will make unremitting efforts to make new contributions to the enterprise.
Second, be brave in tackling difficulties and solving problems.
With my intelligence and professional skills, I solved a series of problems for the maintenance and manufacturing center together with the masters, and overcame one difficulty after another.
In April this year, the maintenance and manufacturing center informed me that there was a car with load reverse gear, which was repaired several times but failed to be repaired. As soon as the car was repaired, my master and I immediately took the tools to test drive with the driver. When driving, we found that the reverse gear automatically jumped in the desert section. The driver said: the problem appeared three months ago, but I couldn't find it. After discussing with the master, I judged that the driver said that it had been replaced and no problems were found. After the test run, my master and I checked it again in detail, and we still determined that it was an inverted slide. After disassembling the gearbox, it was found that the toothed hoop used in reverse gear was abnormal. Although the size is the same, the shape of the teeth is different, which is the direct cause of gear shifting. After the replacement, the fault was successfully eliminated, which not only relieved the driver's troubles, but also saved a lot of money for the company.
Third, love and dedication, warm service.
"Standing to be a man, kneeling to serve" is the service concept of transportation companies. At work, I have seen many vehicles with brake failure while driving. I have made an in-depth analysis of this kind of problems and come to the conclusion that there are several reasons for the failure of braking when driving: insufficient compressed air pressure generated by the braking system.
Because the air cylinder of the vehicle cannot store enough compressed air, the air source of the brake valve is insufficient; The air leakage of the brake valve pipeline and the blockage of the air path will cause insufficient compressed air pressure generated by the brake system during braking; The gap between the brake drum and the brake shoe is not suitable; The contact area of the brake shoe is too small. According to the above reasons, around the problem of brake failure, I have consulted and studied relevant maintenance materials many times, humbly consulted experienced teachers, and examined and analyzed the possible reasons one by one. For the part that may fail, I will adopt the method of "from shallow to deep, from easy to difficult". I'll check the air storage tank first to see if the air pressure meets the standard. Start the engine, check the pressure gauge response of the brake system, and find it difficult to inflate. Expansion >; It takes 3 minutes to charge to 0.3MPa, which may be due to the failure of the air compressor or the leakage of the sealed air pressure pipeline, which makes it difficult to increase the air pressure. I checked the air pressure when the engine was running at a medium speed and found that it was rising slowly. After the flameout, I checked the air pressure and found that the air pressure dropped rapidly, exceeding the standard value.
Check whether the tightness of the air compressor drive belt meets the requirements, and then remove the air compressor. It is found that most of the pump cover has carbon deposits, and the air inlet is also blocked by carbon deposits. After removing the carbon deposit, put it back on the pump cover and accessories. Found that the effect is better than before. The air compressor has obvious pumping sound and good working effect. Then connect the output throat of the air compressor to continue to start the engine, gradually relax the test air volume of the pipelines in front of the main valve, and then completely remove the carbon deposits on the blocked pipelines.
Through the above operation, the air pressure can reach above 490 kPa shortly after the engine is started. I judged the fault according to the pressure drop after stepping on the brake pedal, and found that the pressure drop was normal. However, after the pedal is released, the exhaust volume of the exhaust valve is insufficient. I immediately disassembled and inspected the master brake valve, and found that there was an obvious groove on the valve glue of the intake valve. The valve glue of the exhaust valve is not properly closed. After modification, I adjusted the exhaust valve, and then I adjusted the gap between the brake shoe and the brake drum of the rear wheel to the best position, so that there would be no delay.
And check whether the extension stroke of the push rod of the front and rear four-wheel brake air chambers reaches the specified value. The stroke of the front wheel push rod should be 15 ~ 35mm, and the stroke of the rear wheel push rod should be 20 ~ 40mm. Unexpectedly, in the process of inspection and adjustment, it was found that the push rod of the left and right wheel brake air chamber was laborious, slow and inflexible. When the air inlet pipe of the brake air chamber is disassembled, air is exhausted, which proves that the air pipe joint is not blocked and the valve glue is not leaked, which indicates that the reason for this phenomenon may be that the lubrication is not serious enough during the first-level maintenance, or that the camshaft and bushing are rusted due to long-term loss of grease, resulting in difficult thrust and short push rod stroke.
Therefore, jack up the wheel, then turn the wheel and try to press the brake pedal. Sure enough, the wheels stopped slowly instead of immediately, which proved that the camshaft had lost its function. Immediately remove the left and right wheels and the brake cam push rod for rust removal and lubrication adjustment, clean the entire brake drum to 1200, and check the tension of the brake shoe return spring. Intuitively, the spring has been corroded a lot. Comparing the old and new springs, it is confirmed that there are differences in elasticity and thickness, so a new one is replaced. After replacing it with a new one, the fault was eliminated. After the test run, the original brake failure of the car was eliminated.
Fourth, strengthen self-cultivation and move closer to the party.
As the saying goes, "It's never too old to learn". I have been strict with myself in all aspects and strive to improve myself in order to adapt to the situation of social development more quickly.
Actively study political theory through newspapers, magazines and books; By reading a lot of books on moral cultivation, we can dissect ourselves, analyze ourselves, face ourselves squarely and improve our quality. Abide by the law and study legal knowledge seriously; Love my job, actively study professional knowledge, have a correct working attitude and be serious and responsible.
At work, I deeply felt the strength and mission of the staff. The kind and simple staff are unknown, conscientious and studious in extremely difficult environment, and their fearless spirit in the face of difficulties deeply touched me.
Although I have never suffered anything since I was a child, I can't easily miss this great opportunity to make up lessons. By strengthening study and combining with the excellent party member around me, I will constantly improve my theoretical level and thoughts.

Time flies, 20 _ _ _ First of all, I would like to thank monitor Zhang, director Cai and director Hou for giving me this opportunity to learn technology, and thank my colleagues for their help and support during this time. Looking back on the study in the past few months, although I am very tired at work, it does not prevent my "sunny heart" from enjoying the dribs and drabs at work. I have benefited a lot from the internship with my heart, mainly in the following aspects.
First, the technical aspect. In the process of learning, what I feel most is: on paper, I don't know what to say. There is still a gap between theoretical knowledge and practical operation. Through this study, I can consolidate the conceptual knowledge of automobile structure, let me get in touch with the real thing emotionally and improve my practical ability. Now that we know the maintenance workflow, we can do some simple steam mold maintenance.
Second, the ideological level has improved a lot. In the sultry weather, I can still study on time, temper my will and make my will stronger. In the process of internship, I understand what kind of mentality to face the new environment and new job; How to improve their adaptability in order to become formal technicians more quickly; How to communicate with colleagues (groups) to minimize internal energy consumption.
Third, professionalism. Every colleague in the _ _ _ _ industry can define his current position. In maintenance work, it is common to forget lunch time. Even after work, I can be conscientious and take the work at hand seriously. In the process of maintenance, their sense of responsibility, seriousness and rigor deeply infected me. For the normal production on the production line, we sweated together in the workshop.
Fourth, corporate culture. A good corporate culture can motivate employees to work. The slogan "Leave difficulties to us and convenience to customers" can be seen in every conspicuous position of the company, which shows that the company attaches importance to corporate culture. Our slogan is: give your all, surpass yourself, pursue Excellence and surpass your goals. This slogan urges each of us to pursue more goals and achieve great success.
Fifth, communication is very important. Good communication can achieve the goal of United front. The communication between students, mold repairers and production line personnel, mold repairers and production line personnel, and mold repairers and machine repairers will help employees understand their current tasks and improve work efficiency. The communication between leaders and employees mainly benefits from the company's excellent management system. Through morning meetings, training, technical exchanges, staff meetings, etc. It can not only improve their communication, but also help all employees stand on the United front and manage the company well. I believe that under this excellent management system, as long as "all people are United as one", the _ _ industry will surely get better and better and develop by leaps and bounds. Perhaps for the _ _ _ _ industry, I am just an ordinary passer-by; But for me, _ _ _ _ industry is an irreplaceable landscape in my life. _ _ _ _ With the joint efforts of all staff, the industry will develop better. I will make progress every day like the _ _ _ _ industry.
(1) Strictly maintain standards to ensure the quality of work. Automobile maintenance is the focus of sales manufacturers and customers, and it is also an important index to evaluate the level of a maintenance enterprise. If there is something wrong with the quality, we can't explain it to customers, manufacturers or ourselves. We would rather do this job than "bean curd residue", and our company's attitude is very clear. No matter which contractor, as long as there is a problem with the quality of the project, we will seriously investigate the responsibility and will never tolerate it. All departments should take the quality of work as the top priority, organize competent personnel to focus on it, strengthen the management of the whole maintenance process, ensure that the quality of work meets the requirements, and truly turn each maintenance project into a boutique project and a signboard project.
(two) adhere to the standard operation, to ensure safety in production. In every link of our work, we must always adhere to the working principle of "safety first", establish the concept that safety is benefit, and make great efforts to eliminate hidden dangers in production safety. At present, our company's safety production situation is good and must be maintained. If a safety accident happens, it will definitely have a serious impact on the company's operation, and even more seriously, it will cause great physical and mental harm and economic waste to the victims (possibly ourselves). As a practitioner of every maintenance industry, you should have a personal understanding of this.
(three) adhere to the standard operation, to ensure the effective use of funds. It is certain that the development of the company needs financial support. On the other hand, all departments of the company should also establish a sense of saving and strive to make every penny used in the right place. All departments should rationally use limited funds to ensure the normal operation of the company. All capital expenditures must be strictly controlled, and "one pen" approval shall be implemented. It is strictly forbidden to disclose fund expenditures at will; Maintenance costs should be strictly in accordance with the budget, and every link should be carefully calculated to minimize unnecessary expenses. It is necessary to do things well, but also to tighten spending and save investment.

Through the practice of disassembling cars, I learned a lot, learned the basic structure and knowledge of cars, enhanced the spirit of teamwork, and truly realized the importance of teamwork in my work. At the same time, I also enhanced my ability to face and overcome difficulties actively and bear hardships and stand hard work, laying a good foundation for future adaptation.
For the disassembly of the whole vehicle, we follow strict procedures and have a clear division of labor. Each class is divided into three groups-main disassembly group, disassembly group and data recording group, which play a very important role in our successful disassembly exercise.
Before officially disassembling the vehicle, we first measured the posture of the whole vehicle and took photos of all the postures of the vehicle. After that, I did some preparatory work before disassembling the car, such as power failure, water discharge and oil discharge. After that, it entered the formal disassembly link, and under the guidance of on-site supervision, the disassembly of the whole vehicle was carried out in a tense and orderly manner. First, four doors and two covers were removed. Because most of my colleagues have no experience in disassembling cars and have not found the skills to disassemble cars, the speed of disassembling cars is very slow. Then start to remove the bumper and fender. Before disassembling the car, I always thought that the bumper was made of materials with equivalent strength, such as metal, but when disassembling the car, I found that the bumper we dismantled was plastic, which was somewhat difficult to understand. How does the bumper play an insurance role in the event of a traffic accident? Through other people's explanation, I walked out of the misunderstanding that the bumper must be made of metal. The original use of plastics also has its advantages. The main function of the bumper on the bus is to absorb some energy during collision, so as to ensure the safety of the occupants in the bus. There is no energy absorption block behind the front bumper of our car, and the other two cars have energy absorption blocks, so its energy absorption effect may be better. In addition, the bumper can also play a decorative role and reduce the weight of the vehicle. I think it may have something to do with pedestrian protection. Also, I don't quite understand the names and functions of the lights in the car. Through the explanation of the electrical engineer, I learned the names and functions of the lights in the car. Later, I consulted the director Song of our class, and deepened my understanding of the lighting system, thus distinguishing high beam, low beam, position light, brake light, turn signal and backup light. There are many such things. I think if I didn't take part in the disassembly practice of the vehicle, I would still be a car-blind, and I don't even know the most basic car knowledge. After that, we successively dismantled the chassis of the vehicle, including clutch transmission, front axle, rear axle, front suspension, rear suspension and related structures of braking and steering, and then removed the engine. In vehicle disassembly, the engine and transmission are not disassembled, but disconnected at the clutch. Before disconnecting the clutch, I also read the structure of the clutch in books, but I still don't understand what is going on after reading it for a while. After removing the clutch, I asked a few colleagues who understood. Under their patient answers, I basically understood the working principle of the clutch. Some things are sometimes incomprehensible by reading, but it is much easier to understand by observing things and other people's explanations. There are still many things to learn in the future, so we must pay attention to methods in the process of learning, and only by using the right methods can we get twice the result with half the effort.
The process of disassembly fully embodies the importance of teamwork. In the process of disassembly, many people are doing different jobs, and each job should cooperate with each other, otherwise it is easy to make mistakes. For example, if the detacher works too fast, the recorder may not keep up, and it is easy to remember wrong, which will also affect the subsequent data login work; Before each step of disassembly, photos should be taken, that is to say, the dismantler and photographer should cooperate, and at the same time, they should record photos and cooperate with the recorder.
Since we will change jobs after a while, each of us knows something about different jobs and has done every step of disassembling the car. Apart from disassembly, information arrangement and data recording of parts are also very important and boring, but these two tasks need to be more detailed and serious. The measurement of standard parts is relatively simple, as long as some key information such as nominal diameter, thread length, end face thickness, end face diameter and weight are measured. However, some parts are more complicated. We should not only measure the basic dimensions such as length, width and height, but also analyze their differences. Some parts have as many as a dozen to dozens of holes, and some gaps are difficult to measure, which requires care and patience, in addition to recording their additional information. This is especially true in the work of data entry. Faced with a large number of data, pictures and forms, it is more likely to make mistakes. Therefore, every link of every job needs everyone's meticulous patience and needs everyone's efforts and cooperation.
In addition to the disassembly of the whole vehicle, I also participated in the disassembly of the Camry seat, and also disassembled the transmissions of Triumph and Elysee with my colleagues in the transmission group of the chassis. Originally, I thought the seat was relatively simple, but only after taking part in the disassembly of the seat by the staff of Dongfeng Lear did I know that the car seat was not that simple. There are many problems to be considered in the design of seats, such as cost and manufacturing technology. Because I am engaged in transmission-related work in the future, I am more serious and careful when disassembling the two transmissions, and I have also sorted out many problems that I didn't understand before, analyzed their respective gear shifting mechanisms, and compared the advantages and disadvantages of the two transmissions. Although both transmissions are produced by the same company and have similar overall structures, there are still many differences in details. For example, although the gears on the two-speed reverse shaft are directly shifted through the reverse fork, the Arc de Triomphe transmission can ensure that the reverse gear rotates with the input shaft at any time, thus ensuring the synchronization of the three reverse gears when the reverse gears are engaged, while the Elysee transmission does not have this structure.
Learned a lot, but also exposed some problems. At first, everything was novel, so I was more motivated. In the last few days, I was not very active because my work was not good and boring. I should also reflect on the following. My future works can't be new forever. How to keep my enthusiasm for work is very important. I must learn from those who work actively.
I want to thank the company for providing such a good opportunity, and I also want to thank the people who helped me enthusiastically, so that I learned a lot through the disassembly internship, and also reserved some relevant knowledge for future work. In addition, in the process of disassembling the car, I also know the problems that should be paid attention to in the design process, such as minimizing the quality of parts, considering the processing technology when designing, using appropriate technology and materials to reduce costs, reasonable design, and easy installation and maintenance. Although the practice of disassembling cars is only the beginning of our work, there are still more things to learn in the future work, but the knowledge and correct working methods we have learned from it can be brought to the future work. As long as we persist in continuous learning and correct working methods, no matter what problems we encounter in our future work, they will eventually be solved.
