Slip ring grinding machine of high-power motor rotor

Abstract

The invention discloses a slip ring grinding machine of a high-power motor rotor. The slip ring grinding machine comprises a magnetic base, a universal support arm, and millstones; one end of the universal support arm is fixed on the magnetic base; an arc fixing bracket is arranged at the tail end of the universal support arm; a plurality of millstone grips are fixed on the arc fixing bracket; the millstone grips are vertically and uniformly distributed along the arc fixing bracket, and one millstone is arranged on each millstone grip. According to the invention, the problems that when manual grinding is adopted, the overall roundness of the slip ring cannot be guaranteed and the grinding efficiency is low, although the local surface of the slip ring is smooth are solved. The slip ring grinding machine has the advantages of being high in grinding quality, low in maintenance cost, convenient and practical, etc.

Description

technical field [0001] The invention relates to a dresser, in particular to a dresser for a slip ring of a high-power motor rotor. Background technique [0002] The wear of the rotor slip ring of a high-power motor is an important aspect of the daily maintenance of the motor. The smoothness of the slip ring surface is a key factor affecting the service life of the brush, the temperature of the brush, and the electrical conductivity of the brush and the slip ring. If the surface of the slip ring is rough, with dents or bumps, the brush will be severely worn, the electrical conductivity will be reduced, the maintenance cost will increase, and the toner will increase, which will reduce the insulation of the slip ring and cause the motor to have grounding faults. Cause downtime to affect production. [0003] In view of the above-mentioned wear and tear problem of the rotor slip ring of high-power motors, at present, domestic motor maintenance personnel mostly use artificial san...

AI Technical Summary

Problems solved by technology

If the surface of the slip ring is rough, with dents or bumps, the brush will be severely worn, the electrical conductivity will be reduced, the maintenance cost will increase, and the toner will increase, which will reduce the insulation of the slip ring and cause the motor to have grounding faults. cause downtime to affect production

[0003] In view of the above-mentioned wear and tear problem of the rotor slip ring of high-power motors, at present, domestic motor maintenance personnel mostly use artificial sandpaper to maintain the slip ring. The surface of the ring is smooth, and the roundness of the slip ring cannot be guaranteed by manual grinding.

[0004] In addition, for the wear problem of the slip ring of large motors, it is necessary to adopt the method of power failure manual grinding - power transmission to rotate the motor - and then power failure manual grinding, which is time-consuming and laborious, and the grinding quality cannot be guaranteed
