Abstract

The invention relates to the technical field of motor press-fitting equipment, in particular to a three-phase asynchronous motor rotor mandrel press-fitting device which comprises a bottom plate, an auxiliary hole is formed in the middle of the bottom plate, and a plurality of through grooves are evenly formed in the bottom plate and distributed in an annular mode. The length direction of the through groove is along the radial direction of the process hole in the bottom plate; the multiple sets of clamping plates are kept in the vertical direction; the equipment can effectively improve the positioning precision of the iron core, the motor shaft and the iron core can be conveniently kept opposite in position, the situation that the motor shaft collides and damages the iron core when the distance deviation between the axis of the motor shaft and the axis of the iron core is large is avoided, parts are conveniently protected, the press-fitting precision of the equipment is improved, and the production efficiency is improved. And meanwhile, the iron core can be conveniently and synchronously fixed, the situation that the motor shaft cannot be normally pressed into the iron core due to sliding deviation of the iron core caused by stress during press fitting is avoided, the running stability of equipment is improved, and the practicability is improved.

Description

technical field

[0001] The invention relates to the technical field of motor press-fitting equipment, in particular to a three-phase asynchronous motor rotor core shaft press-fitting device. Background technique

[0002] As we all know, when the rotor in the three-phase asynchronous motor is processed, the motor shaft needs to be pressed into the iron core to form a complete rotor. When the existing press-fitting equipment is used, the iron core is first placed in the mold on the workbench. , and then push the motor shaft through the hydraulic press to insert into the iron core. Since the motor shaft and the tight fit are usually in an interference fit state, the motor shaft and the tight fit are connected to complete the pressing work of the rotor. However, for the convenience of the iron core in the mold Normal movement, the positioning accuracy of the mold to the iron core is low. When the motor shaft is press-fitted with the iron core, the deviation distance between the ...
