Description

Technical Field

[0001] The utility model relates to the technical field of motor shaft polishing equipment, in particular to a surface polishing device for machining a motor open shaft. Background Art

[0002] The motor open shaft usually refers to the output shaft of the motor, also called the motor shaft. The motor shaft is the component that connects the motor rotor to the external transmission device or load. It is responsible for transmitting the rotational force generated by the motor to the external device to achieve mechanical movement or drive other equipment to work.

[0003] In order to improve the surface finish and precision of the motor open shaft and ensure the normal operation and transmission efficiency of the motor, workers need to polish the motor open shaft. At present, the traditional motor open shaft polishing is mostly done by workers holding a sandblasting gun to sandblast the shaft surface. This method is time-consuming and labor-intensive, and it is difficult to control the polishing accuracy. In addition, the abrasives and dust splashed during the polishing process will also affect the health of the workers. Utility Model Content
