AI Technical Summary

Technical Problem

During the turning process of the existing commutator surface precision turning device, metal debris is easily left in the commutator reversing sheet gap, affecting the flatness of the surface, resulting in a decrease in motor performance or short circuit between commutator plates.

Method used

A turning device including a positioning plate, an electric push rod, a brush roller and other components is designed. Through the sliding of the positioning plate and the driving of the electric push rod, the stable positioning of the commutator during the turning process, and the debris in the gap of the reversing sheet is cleaned using the brush roller.

Benefits of technology

It effectively avoids motor performance degradation and commutator failure caused by debris residue, improves the flatness and turning efficiency of commutator surface, and simplifies the cleaning and storage process of multiple commutators.

Abstract

The present invention belongs to the technical field of commutator processing, and specifically is a turning device for finishing the surface of a commutator, comprising a workbench, an adjusting plate is rotatably provided on one side of the upper end surface of the workbench, a rotating seat is rotatably provided in the middle of the upper end surface of the adjusting plate, a slide block is fixedly connected to the left end of the second slide rod, a turning tool is slidably connected to the inner side of the slide block, and a stacking correction type cleaning mechanism for clearing debris in the commutator segment gap of the commutator is also provided on the workbench. The present invention realizes the use of a stacking correction type cleaning mechanism to comprehensively clean the debris in the commutator segment gap, avoiding the situation where the flatness of the commutator surface is affected due to debris remaining in the commutator segment gap, and then the motor performance is reduced, or even the commutator segments are short-circuited, causing motor failure.
