Device for assembling stator and rotor of motor

Abstract

The invention discloses a device for assembling a stator and a rotor of a motor. The device comprises a sliding plate and a lifting platform, wherein the sliding plate and the lifting platform are arranged in parallel; the sliding plate is fixed, the lifting platform moves in a direction vertical to the sliding plate to be close to or far away from the sliding plate; the sliding plate is provided with a mounting hole a; and the lifting platform is provided with a mounting hole b, and the center line of the mounting hole b and the center line of the mounting hole a are coincided. By applying the device for assembling the stator and the rotor of the motor in the scheme of the invention, the stator and the rotor are easy and convenient to assemble, and a bearing can accurately enter into a bearing room; and assembling is convenient and accurate, the winding of the stator can not be impacted, and parts of the motor can be prevented from being damaged by attractive force of the stator and the rotor when a permanent magnet motor is assembled, thus the motor production efficiency and the motor production quality are effectively improved.

Description

technical field [0001] The invention relates to a device for assisting motor assembly, in particular to a motor stator and rotor assembly device, which belongs to the technical field of motor assembly devices. Background technique [0002] In the motor production industry, the assembly of motor stator and rotor is a headache for every manufacturer and assembler. This is because the air gap between the inner wall of the motor stator and the outer wall of the rotor is relatively small. During assembly, if you do not pay attention to it, the winding of the stator will be damaged, resulting in the assembled motor not being used normally, increasing the rework rate and The scrap rate affects the production schedule. Moreover, with the development of the motor industry, the application of permanent magnet motors has become more extensive, but the magnetic steel of permanent magnet motors has a strong suction force. When assembling the stator and rotor, the permanent magnet rotor ...

AI Technical Summary

Problems solved by technology

This is because the air gap between the inner wall of the motor stator and the outer wall of the rotor is relatively small. During assembly, if you do not pay attention to it, the winding of the stator will be damaged, resulting in the assembled motor not being used normally, increasing the rework rate and Scrap rate, affecting production progress

Moreover, with the development of the motor industry, the application of permanent magnet motors has become more extensive, but the magnetic steel of permanent magnet motors has a strong suction force. When assembling the stator and rotor, the permanent magnet rotor will be attracted as soon as it approaches the stator. It is very difficult to assemble the stator and rotor if you do not pay attention to it. At the same time, it also reduces the production efficiency and production quality to a large extent.
