AI Technical Summary

Technical Problem

Existing positioning fixtures, during the stamping process of battery connecting pieces, employ telescopic and abutment methods, which makes the connecting pieces prone to detaching from the positioning and unable to withstand impacts and vibrations.

Method used

The pressing and positioning component is combined with a lead screw module. The lifting plate and return spring are driven by a cylinder to achieve pressing and positioning. The position of the positioning component is adjusted by the lead screw module and the spacing of the limit clamp is adjusted to ensure the stability of the battery connecting piece during the stamping process.

Benefits of technology

It improves the positioning effect and flexibility of the battery connector during the stamping process, avoids displacement caused by impact and vibration, and enhances the stability of the stamping process.
