Rotor shaft end locking device and method

Abstract

The invention relates to a rotor shaft end locking device and method. The rotor shaft end locking device comprises a positioning shaft sleeve, a fixing shaft sleeve and a locking shaft sleeve, wherein the front end of the fixing shaft sleeve is fixed on a supporting seat; the locking shaft sleeve and the positioning shaft sleeve are arranged in the fixing shaft sleeve in a sleeving manner; the locking shaft sleeve is arranged at the front part, the positioning shaft sleeve is arranged at the rear part, and the front end of the locking shaft sleeve extends from the front end of the fixing shaft sleeve; a shaft hole of the fixing shaft sleeve is an eccentric hole, a shaft hole of the locking shaft sleeve is also an eccentric hole, and the eccentric distance of the shaft hole of the fixing shaft sleeve is the same as that of the shaft hole of the locking shaft sleeve, and eccentric directions are opposite. The locking method comprises the following steps of fixing the front end of the fixing shaft sleeve to the supporting seat; sequentially mounting the locking shaft sleeve and the positioning shaft sleeve in the shaft hole of the fixing shaft sleeve in a sleeving manner; enabling the front end of the rotor shaft allowed to be magnetized to extent into the shaft hole of the locking shaft sleeve and the shaft hole of the positioning shaft sleeve; and rotating the locking shaft sleeve so that the rotor shaft is locked and is no longer flexible. According to the rotor shaft end locking device disclosed by the invention, damage to the surface of the rotor shaft is avoided, and the rotor shaft end locking device is convenient to disassemble and assembly, and firm to lock, and the efficiency is improved.

Description

technical field [0001] The invention relates to a rotor shaft clamping device, in particular to a rotor shaft end locking device and a locking method thereof which can protect the surface quality of the rotor shaft and facilitate repeated disassembly and assembly. Background technique [0002] The production of the motor rotor shaft needs to go through various processes such as magnetization, and the rotor shaft needs to be clamped repeatedly. As for the servo motor, due to its very strict requirements on the servo performance and control accuracy, it is required that the surface of the rotor shaft of the motor can still guarantee the due quality to the greatest extent after the production of various processes, and reduce the damage to the surface of the rotor shaft . However, the current clamping equipment, on the one hand, is inconvenient to disassemble and assemble, time-consuming and laborious, on the other hand, it will still cause damage to the surface of the rotor sh...
