AI Technical Summary

Technical Problem

In the existing technology, it is difficult to design the spring in the shot peening machine. The spring cannot be effectively positioned during the shot peening process, resulting in damage or deformation of the spring. In addition, it has poor versatility and cannot adapt to irregularly shaped springs.

Method used

A spring stress shot peening fixture was designed, including a top plate, a bottom plate, an upper spring seat, a lower spring seat, a guide rod, and a positioning assembly. Through detachable connections and the cooperation of the positioning assembly, the spring is ensured to maintain the desired height and position during shot peening, avoiding damage, and adapting to different types and irregular shapes of springs.

Benefits of technology

It achieves effective positioning of the spring during the shot peening process, avoids damage, improves the shot peening effect, enhances the versatility of the fixture, and is suitable for various shot peening equipment and irregularly shaped springs.
