AI Technical Summary

Technical Problem

In the existing technology, the grounding system of the rotary welding device is not suitable for rotary welding, and it occupies a large area, which leads to frequent adjustment of the welding position of the roller, affecting the welding quality.

Method used

A grounding assembly consisting of a bracket, outer shaft ring, fixing ring, clamping block, and connecting rod is adopted. Through the stepped contact between the clamping block and the roller body and the lateral clamping of the abutment block, combined with the rotation structure of the inner and outer shaft rings, the roller body is stably grounded and supported, avoiding interference and displacement during rotation welding.

Benefits of technology

Stable grounding of the roller body was achieved during rotary welding, avoiding interference from the grounding wire, ensuring welding quality, and extending the service life of the device.
