AI Technical Summary

Technical Problem

The existing equipment has a problem where the stud is positioned too high before welding, resulting in an unsightly and weak weld point after stud projection welding.

Method used

By setting up an electric telescopic rod and linkage system, the elasticity of the spring pushes the linkage to lock the stud, and the electric telescopic rod automatically compresses to drive the stud downward. Combined with the design of the clamping plate and pressure plate, the stud is ensured to be in an accurate position before welding, preventing shaking.

Benefits of technology

This effectively prevents the problems of unsightly and weak weld points caused by excessively high stud positioning before welding, while ensuring that the object is firmly fixed during the welding process and avoiding poor welding results.
