Abstract

The invention relates to the field of hollow shaft machining, and discloses a finish-grinding treatment method for preventing hollow shaft center deformation. The method comprises the following stepsof (1) heat treatment, wherein heat treatment is conducted on a hollow shaft formed by rough machining; (2), central hole correction, wherein the hollow shaft subjected to heat treatment in the step (1) is mounted on a finish-grinding treatment device, and finish-turning is conducted on central holes in the two ends of the hollow shaft to enable the central holes to be circular; and (3) outer circle finish-grinding, wherein the hollow shaft treated in the step (2) is mounted on a grinding machine, tips on the grinding machine are inserted into the two ends of the hollow shaft respectively, andthen a grinding wheel on the grinding machine is started to conduct finish-grinding on the outer circle of the hollow shaft. By means of the method, the problem that the cylindricity of the outer circle of the hollow shaft is poor due to deformation of the hollow shaft after heat treatment can be solved.

Description

technical field [0001] The invention relates to the processing field of hollow shafts, in particular to a fine grinding treatment device and method for preventing central deformation of hollow shafts. Background technique [0002] In a traditional motor, the motor has an output shaft that transmits torque, and usually the torque transmitted by the motor will be output after being decelerated by the gear set, so the traditional motor also needs to install a fixed gear on the output shaft, but now In the application of new energy vehicles, in order to make the structure of the motor simpler and more compact, and reduce the weight of the motor output shaft, a thin-walled hollow shaft has been used to replace the output shaft of the traditional motor, and the thin-walled hollow shaft The part protruding from the motor is fixed coaxially with the gear, which optimizes the structure of the motor while facilitating the output of torque. [0003] However, in the process of processi...
