Portable slip ring electric grinding device and application method

Abstract

The invention discloses a portable slip ring electric grinding device and an application method. The method is an equipment maintenance technology, and overcomes the defects of the prior art. The device comprises a base, a movable bracket, a clamp spring clip, an electric grinding machine and a rotatable fine adjustment handle, the movable bracket is connected to the base, the rotatable fine adjustment handle is mounted in the middle of the movable bracket, one end of the rotatable fine adjustment handle is connected with the clamp spring clip, and the electric grinding machine is fixed to theclamp spring clip.

Description

technical field [0001] The invention relates to equipment maintenance technology, in particular to a portable slip ring electric grinding device and an application method. Background technique [0002] After the compressor has been running for a period of time, the slip ring will appear uneven. If it is not dealt with in time, it will cause insufficient pressure on the circlip, resulting in loose carbon brushes and burning the slip ring. Because there is no on-site treatment equipment, usually The best way to deal with it is to disassemble the motor, take away the slip ring, return to the factory for repair, and reinstall the motor. This maintenance method has the following disadvantages: [0003] One is to remove the slip ring, you need to remove the base of the motor, and remove the bearing bush. To remove the slip ring, you have to disassemble the entire motor. Otherwise, the slip ring cannot be removed. Frequent disassembly of the motor will inevitably shorten the life ...

AI Technical Summary

Problems solved by technology

[0003] One is to remove the slip ring, you need to remove the base of the motor, and remove the bearing bush. To remove the slip ring, you have to disassemble the entire motor, otherwise the slip ring cannot be removed. Frequent disassembly of the motor will inevitably shorten the life of the motor, and the motor itself does not If there is no fault, it means that the motor will be forced to undergo a major operation when there is no disease.

[0004] The second is that the slip ring is returned to the factory for maintenance using a lathe. The contact between the turning tool of the lathe and the slip ring will produce force and reaction force, which will cause the slip ring to move back and forth, and the smoothness of the slip ring after grinding cannot reach the ideal effect. The circlip described above is often broken, the main reason for the carbon brush to ignite

[0006] The fourth is that the bearing bush of the motor has been run-in in the original operation, and then the motor base and the bearing bush are disassembled and reinstalled. There will be a certain error with the previously run-in bearing bush, which will inevitably reduce the service life of the motor.
