Description

Technical Field

[0001] The utility model relates to the technical field of motor processing, in particular to a slip ring grinding structure used for motor processing. Background Art

[0002] The slip ring is an electrical component responsible for connecting the rotating body and transmitting energy and signals. The function of the motor slip ring is to lead the rotor to the outside to facilitate the measurement of rotor current, control of motor speed, adjustment of reactive power, etc. After the hoisting equipment motor has been running for a long time, the contact between the motor carbon brush and the commutation pole will cause the contact area of ​​the carbon brush to become smaller due to long-term friction. The motor slip ring is very likely to generate sparks, scars and oxidation when the carbon brush rubs and conducts electricity, causing damage to the motor slip ring, so the slip ring needs to be polished.

[0003] For example, the Chinese patent publication number CN214080700U discloses a slip ring inspection and polishing device, which includes a box body, a support plate fixedly installed on the left side wall of the box body, a motor fixedly installed on the top of the support plate, the output end of the motor passes through the side wall of the box body and is fixedly connected to a rotating shaft, the rotating shaft is symmetrically provided with external threads, and the two external threads are in opposite directions, the rotating shaft is symmetrically threaded with a slider, and the top of the slider is fixedly installed with a push plate. The device controls the forward and reverse rotation of the motor to control the slider to move horizontally on the rotating shaft, and then drives the clamp to fix the slip ring. However, there are still some problems in the use of this device.

[0004] The existing slip ring grinding device fixes the slip ring through a clamping block. Since the slip ring is mostly annular in shape, it is easy to shake during grinding, and only a part of the slip ring surface can be ground, which is inefficient. Therefore, the utility model proposes a slip ring grinding structure for motor processing to solve the above problems. Utility Model Content
