Tooling fixture design is generally carried out in accordance with the specific requirements of a process after the development of the machining process of the part. The process should be developed with full consideration of the possibility of fixture realization, while the design of workholding fixtures, if necessary, can also propose modifications to the process. The quality of the design of workholding fixture should be measured by whether it can ensure the processing quality of workpiece stably, high production efficiency, low cost, convenient chip removal, safe operation, labor-saving and easy manufacturing and maintenance, etc.
The basic principles of Tooling fixture design
1、To meet the stability and reliability of workpiece positioning in the process of use.
2、To have sufficient load-bearing or clamping force to ensure the machining process of the workpiece on the workholding fixture.
3, to meet the simple and fast operation in the process of clamping.
4, vulnerable parts must be a structure that can be quickly replaced, preferably without the use of other tools when conditions are adequate.
5, to meet the reliability of repeated positioning of the fixture in the process of adjustment or replacement.
6、As far as possible to avoid complex structure and expensive cost.
7、To use standard parts as constituent parts as far as possible.
8、Form the systemization and standardization of products within the company.
