Stator and rotor press-fitting device

Abstract

The invention aims to provide a stator and rotor press-fitting device which is better in press-fitting effect and higher in press-fitting efficiency. The stator and rotor press-fitting device comprises a positioning plate, a limiting plate, a movable rod, a first lifting device, a second lifting device, a linear motion device and a pressing machine, wherein the first lifting device is used for controlling the up-and-down movement of the positioning plate, the second lifting device is used for controlling the up-and-down movement of the movable rod, the linear motion device is used for controlling the back-and-forth movement of the limiting plate, the pressing machine is used for controlling the up-and-down movement of a pressing block, the positioning plate moves upward so as to clamp a stator between the positioning plate and the limiting plate, the positioning plate is provided with a first through hole which vertically runs through so as to enable the movable rod to pass through, the limiting plate is provided with an open slot which vertically runs through and is provided with a forward opening so as to enable an upper end of the movable rod to pass through, the movable rod isprovided with a lower positioning hole matched with the lower end of a rotor shaft, the pressing block is provided with an upper positioning hole matched with the upper end of the rotor shaft, and theupper positioning hole and the lower positioning hole are coaxially arranged.

Description

technical field [0001] The invention relates to a device for assembling a motor, in particular to a press-fitting device for a stator and a rotor. Background technique [0002] Some motors use the stator as the motor casing, which needs to be assembled between the stator, the rotor and the end cover. The magnetic attraction force is very large, and the rotor is often adsorbed on the inner wall of the stator to make the rotor shaft tilt. The press-fitted rotor has problems of difficult rotation and high noise; and in the prior art, the press-fitting at both ends of the rotor shaft is carried out separately However, it takes a long time to press and install, and it is difficult to ensure the coaxiality among the stator, rotor and end cover. Contents of the invention [0003] The purpose of the present invention is to provide a stator and rotor press-fitting device with better press-fit effect and higher press-fit efficiency. [0004] In order to achieve the above object, t...

[0002] Some motors use the stator as the motor casing, which needs to be assembled between the stator, the rotor and the end cover. The two ends of the rotor shaft of the rotor need to be pressed with the stator bearing and the end cover bearing respectively; The magnetic attraction force is very large, and the rotor is often adsorbed on the inner wall of the stator to make the rotor shaft tilt. The press-fitted rotor has problems of difficult rotation and high noise; and in the prior art, the press-fitting at both ends of the rotor shaft is carried out separately It takes a long time to press and install, and it is difficult to ensure the coaxiality among the stator, rotor and end cover
