Description

Technical Field

[0001] This utility model relates to the field of slip ring grinding, and in particular to a slip ring grinding device. Background Technology

[0002] Slip rings, as core components for dynamic conductivity in rotating equipment, are widely used in motors, generators, industrial robots, and other fields. They transmit current or signals through the sliding contact between a ring conductor and a brush. After long-term operation, they are prone to surface damage due to mechanical friction, electrical spark corrosion, or environmental factors (such as dust and humidity). Specifically, this manifests as increased surface roughness, carbon powder or impurity residue, oxidation of the metal surface forming an insulating oxide layer, and even localized pitting or ablation. Ultimately, this leads to poor conductive contact—increased contact resistance and intensified electrical sparking, which can severely cause equipment shutdown or electrical failures.

[0003] Currently, the repair technology for slip ring surface damage mainly relies on traditional lathe machining. This method requires completely disassembling the slip ring from the main body of the equipment and then grinding it on a lathe. However, this method is time-consuming to disassemble and assemble, results in long equipment downtime, and is costly. Therefore, improving the convenience and efficiency of slip ring repair and grinding has become an urgent technical problem to be solved. Utility Model Content
