Motor slip ring online repair apparatus

Abstract

The invention discloses a motor slip ring online repair apparatus. A horizontal sliding groove (102) and a fixed bracket (106) are arranged on a fixed support base (101); a slip ring processing machine tool (2) is arranged at the lower end of a perpendicular sliding block (108); the perpendicular sliding block (108) extends into a cover shell (7) of a motor slip ring (6); a lead screw (3) is alsoarranged on the side surface of the fixed support base (101); a perpendicular toothed groove (113) is formed in the horizontal sliding groove (102); and a clamping tooth block (112) is arranged on thefixed bracket (106). In slip ring reaping, detaching of the slip ring from the motor is not needed, instead, only the cover shell of the motor slip ring needs to be detached, so that fault power downtime caused by slip ring detachment and installation can be avoided; the feeding magnitude in slip ring repairing can be controlled extremely easily, so that high processing precision and high smoothness and tidiness of the repaired slip ring are realized; and when the repair apparatus is used for repairing of the motor slip ring of a crane, convenience in use, and shortening of fault processingtime and power down time are realized.

Description

technical field [0001] The invention relates to the field of repairing damage to motor slip rings, in particular to a slip ring repairing and processing device without dismantling the motor. Background technique [0002] The beginning of each phase winding in the three-phase winding of the wound motor is connected to three copper slip rings, and the slip rings are fixed on the motor shaft and rotate with the shaft. The brush in the wound motor is a conductive component that makes sliding contact with the slip ring to form an electrical connection. The brush acts on the slip ring as a sliding contact body for importing and exporting current. In order to ensure continuous contact between the brush and the slip ring, there is a certain pressure between the brush and the slip ring. [0003] After the winding motor runs for a period of time, due to the long-term sliding friction between the slip ring and the brush, the surface of the slip ring collector ring will have pits, pit...

AI Technical Summary

Problems solved by technology

In the prior art, the brushes are processed after removing the wound rotor for large and medium-sized wound motors. This processing and repair method is very troublesome, and it is easy to damage the stator and rotor coils if you do not pay attention; and the entire motor needs to be dismantled It is time-consuming and labor-intensive, the production and processing cycle is very long, and assembly deviation will occur after reassembly, so it is very important to quickly repair the slip ring online. If the slip ring can be trimmed without disassembling the wound rotor, it will be It can greatly reduce the workload of maintenance personnel, reduce the loss of downtime caused by disassembling the motor, and improve the utilization rate of the motor
