AI Technical Summary
The positioning accuracy of existing positioning fixtures is not satisfactory due to manufacturing errors and wear. This leads to inaccurate positioning, making it impossible to effectively control the positioning accuracy of coil assemblies and resulting in high scrap costs.
An adjustable positioning fixture is provided. By setting an adjustable first positioning block and a second positioning block, the positions of the coil and the terminal block can be adjusted in different directions to ensure that they meet the design requirements and eliminate the influence of manufacturing and wear errors.
It improves the positioning accuracy of coil assemblies, extends the service life of positioning fixtures, reduces scrap costs, and improves the stability of welding quality.
