Dedicated machine for assembly and disassembly of motor rotor assembly, and operating method for dedicated machine

Abstract

The invention discloses a dedicated machine for the assembly and disassembly of a motor rotor assembly, and an operating method for the dedicated machine. The dedicated machine comprises an air cylinder, a pressure plate, fixing bolts, a support, and the motor rotor assembly. The support comprises a supporting plate and a plurality of supporting columns. The supporting plate is installed at the tops of the supporting columns, and the air cylinder is installed on the supporting plate. The air cylinder is provided with an air cylinder push rod, and the central part of the supporting plate is provided with a hole. An end of the air cylinder push rod passes through the hole of the supporting plate, and the end of the air cylinder push rod is connected with a pressure plate. The surface of thepressure plate is provided with a plurality of threaded holes adapted to the fixing bolts. One end of the motor rotor assembly is provided with a plurality of threaded holes adapted to the fixing bolts, and the fixing bolts are used for enabling the threaded holes of the pressure plate to be in fixed connection with the threaded holes of the motor rotor assembly. The original manual disassembly and assembly mode of the rotor assembly is changed into a semi-automatic disassembly and assembly mode, the labor intensity is small, and the production efficiency is improved.

Description

technical field

[0001] The invention relates to the field of electromechanical technology, in particular to a special machine for installing and dismounting a motor rotor assembly and an operation method thereof. Background technique

[0002] In the existing stator-rotor separated servo motor, the rotor assembly needs to be separately installed on the equipment. The rotor assembly is connected by a cylindrical hole or a tapered hole in the middle of the shaft to the main shaft of the machine head through a key or a taper, and the end of the main shaft is locked with a locking bolt and a pressure plate. When the motor rotor assembly is installed, no tooling or special equipment is used, and the force is only transmitted by tapping with a hammer. When disassembling the motor rotor assembly, use a wrench to loosen the locking bolts to remove the pressure plate and bolts, and then use a special bolt with a larger diameter to continuously rotate into the screw hole in the shaft,...
