Basic principles of fixture design

The basic principle of tooling fixture design is that the structure of the tooling needs to be designed according to the actual requirements of the product. If necessary, modifications to the process can be made; the design quality of the tooling fixture should be based on whether it can stably ensure the quality of the workpiece. Processing quality, high production efficiency, low cost, convenient chip removal, safe operation, labor saving and easy manufacturing and maintenance are its measurement indicators.

1. Meet the stability and reliability of workpiece positioning during use;

2. There is sufficient load-bearing or clamping strength to ensure the processing of the workpiece on the fixture;

3. Meet the simple and fast operation during the clamping process;

4. Wearable parts must be of a structure that can be quickly replaced. It is best not to use other tools when conditions are sufficient;

5. Meet the reliability of repeated positioning of the fixture during adjustment or replacement;

6. Avoid complex structures and expensive costs as much as possible;

7. Use standard parts as component parts as much as possible;

8. Form the systematization and standardization of the company's internal products.
