First, the preparation work before assembly

1. Learn and be familiar with the product assembly drawing and related technical data, and understand the product structure, the functions of each part, the mutual relationship and the connection method.

2. Determine the assembly method.

3. Determine the assembly sequence.

4. Clean up the tools, measuring tools and auxiliary tools needed for assembly.

5. Check the parts, purchased parts and standard parts according to the assembly drawing.

6. Clean and wash the assembled parts.

7. Some parts need to be processed with pliers before assembly (such as scraping, repairing, balance test, drilling, reaming, etc.). ).

Second, the assembly work

1. Assembly of parts: The process of assembling parts into parts is called assembly of parts.

2. Assembly: The process of assembling parts into final products is called assembly.

Third, adjustment and accuracy check.

1. Adjustment is to adjust the mutual position of parts or mechanisms, fit the clearance, and combine the tightness. In order to make the mechanism or machine work in harmony (such as the adjustment of bearing clearance, fillet position and gear axial position, etc.). ).

2. Accuracy inspection is to check the working accuracy and geometric accuracy of products with measuring tools or instruments until they meet the technical requirements.

Fourth, painting and painting.

Spray painting is to prevent rusting of raw surfaces and make products look beautiful. Oiling is to prevent the working surface of the product and the machined surface of the parts from rusting.
