AI Technical Summary
The existing welding process for automotive stamping parts nuts suffers from problems such as low efficiency of manual operation, high safety risks, poor production continuity, long changeover time, and high costs.
A nut resistance welding fixture with a multi-functional installation mechanism was designed. It uses a positioning mechanism and a sensor in conjunction with an electric cylinder to drive the positioning pin, so as to achieve automatic and precise positioning and continuous operation. Combined with a hexagonal prism structure and a foolproof design, it can adapt to the rapid changeover of parts of different specifications.
It improved production efficiency, reduced manual adjustment time, decreased defect rate and risk of mechanical injury, and ensured production continuity and quality stability.
