Problems solved by technology

[0005] The invention can solve the problem that the surface processing precision of the output shaft of the motor is not enough, and the outer wall of the outer surface diameter of the grinding shaft is not uniform for many times, which leads to a sudden change in the diameter of the shaft and reduces the fatigue life of the output shaft of the motor; at the same time, the outer surface of the output shaft Uneven surface grinding causes stress concentration, which reduces the service life of the output shaft and other problems

Abstract

The invention provides a motor output shaft surface finish machining device and a machining method of the motor output shaft surface finish machining device. The device comprise bases, an outer box sleeve and an execution device, the bases are symmetrically arranged at the lower end of the outer box sleeve, the outer box sleeve is in a cavity cylinder shape, arc holes are evenly formed in the outer wall of the outer box sleeve, and the execution device is installed inside the outer box sleeve through a bearing. The problems that the surface machining precision of an output shaft of a motor isnot high enough, the diameter of the shaft is abruptly changed due to the fact that the outer wall is not uniform since the outer surface diameter of the shaft is polished repeatedly in sections, andthe fatigue life of the output shaft of the motor is shortened are solved, and meanwhile, the problems that the external surface of the output shaft is not uniformly polished, stress concentration exists, and the service life of the output shaft is shortened are solved.

Description

technical field [0001] The invention relates to the technical field of shaft processing, in particular to a device for finishing the surface of an output shaft of a motor and a processing method thereof. Background technique [0002] The function of the motor is to convert electrical energy into mechanical energy. During the energy conversion process, the output shaft is equipped with a pulley or coupling, and then the torque is transmitted through the belt or coupling to drive the equipment to run and do work; but the motor is interrupted during the working process. Shaft failures occur from time to time, and the fracture locations are basically concentrated at the root of the shaft extension, the root of the bearing position, and the web end of the web shaft. [0003] At present, the reason why the output shaft of the motor breaks during the working process is mainly due to the insufficient surface machining accuracy of the shaft. Due to the uneven diameter of the outer su...
