Polishing device for welded flexible connection copper bar for new energy automobile battery

Abstract

The invention relates to a polishing device of a welded flexible connection copper bar for a new energy automobile battery. The polishing device comprises a polishing table and a polishing plate arranged on the polishing table and used for fixing the copper bar. The polishing plate is provided with polishing bases moving towards or away from each other and driving mechanisms driving the polishingbases to move. The polishing bases are provided with grinding assemblies which are adjustable in spacing distance so as to adapt to polishing of copper bars of different lengths and sizes. Compared with the prior art, through the arrangement of a fixed clamping base, the polishing base, the driving mechanism and the polishing assemblies, the welded position of the copper bar can be quickly polished, no polishing dead corners exist, and the polishing quality and the polishing efficiency are guaranteed; and through the arrangement of an adjusting assembly and a tension belt mechanism, the polishing device can meet the requirement for polishing copper bars of different lengths and sizes, the applicability of the polishing device is improved, and the application range is widened.

Description

technical field [0001] The invention relates to the technical field of production and processing of copper bars for battery connection, in particular to grinding equipment applied to soft connection copper bars for new energy vehicle batteries after welding. Background technique [0002] The existing copper bars for new energy vehicle batteries are also called copper busbars or busbars. They are made of copper and are rectangular long conductors. , The shapes of the copper bars are also various, which play the role of transmitting current and connecting electrical equipment in the circuit. [0003] After the two ends of the existing copper bars have been welded to the mounting plate, the solder joints, solder bumps and burrs generated at the welding point need to be removed, so the connection needs to be polished, and the existing problem is that there is no dedicated copper bar The grinding equipment after welding at both ends leads to only two methods of manual grinding o...

AI Technical Summary

Problems solved by technology

[0003] After the two ends of the existing copper bars are welded to the mounting plate, the solder joints, solder bumps and burrs generated at the welding place need to be removed, so the connection needs to be polished, and the existing problem is that there is no dedicated copper bar The grinding equipment after welding at both ends leads to only two methods of manual grinding or general grinding equipment. Among them, the manual grinding method is inefficient and seriously affects production efficiency; the general grinding equipment method, due to the particularity of the shape of the copper bar, It is often necessary to change the grinding position many times, and there are grinding dead angles, resulting in low grinding quality and long grinding process
