Description

Clamping device for turning end face of motor shaft Technical Field The utility model relates to the technical field of metal material processing, in particular to a clamping device for turning an end face of a motor shaft. Background The motor shaft is a supporting part of the motor rotor, which is connected to the stator part of the motor via bearings for transmitting the mechanical energy of the motor. The motor shaft is typically a cylindrical piece of metal, the shape and size of which varies depending on the type, power and application requirements of the motor. When the motor shaft is processed, the end faces of the motor shaft are required to be machined, so that the flatness of the end faces is ensured, and sometimes the two end faces of the motor shaft are required to be rotated, so that the center device on the subsequent lathe can be effectively fixed. At present, when the length and the size of a motor shaft of the existing clamping and rotating device are changed, the existing clamping and rotating device cannot be effectively fixed, and the subsequent processing efficiency is affected. Therefore, it is desirable to provide a clamping device for turning an end surface of a motor shaft, so as to solve the above-mentioned problems.
