AI Technical Summary

Technical Problem

Existing bicycle frame punching equipment suffers from insufficient stability in positioning, leading to hole position deviation and hole diameter error. Furthermore, the positioning structure cannot be flexibly adjusted, and the clamping mechanism lacks buffer protection, resulting in surface damage and a high scrap rate.

Method used

Employing a moving mechanism and buffer components, the system achieves rapid and precise positioning through a lead screw and guide rod in conjunction with a slider and groove. Combined with upper and lower clamping seats and cylinders, and a buffer component with springs and dampers, it ensures stable positioning and buffers impact forces.

Benefits of technology

It achieves high-precision hole positioning, reduces scrap rate, improves production efficiency and product quality, and prevents damage and deformation of the frame surface.
