Automatic assembling device of rotor and end cover of permanent magnet synchronous motor

Abstract

The invention provides an automatic assembling device of a rotor and an end cover of a permanent magnet synchronous motor. The automatic assembling device comprises a fixed platform, a horizontal moving platform, a radical moving platform, a supporting platform, an end cover transferring platform, a rotor and case transferring platform, an end cover gripping assembly, a rotor gripping assembly and an ejector rod assembly, wherein the end cover gripping assembly comprises a pushing cylinder, a pushing rod assembly, an end cover gripper fixing platform and an end cover gripper; and the rotor gripping assembly comprises a rotor gripper fixing platform, a rotor gripper and a bidirectional cylinder. The working process of the device provided by the invention comprises the steps of firstly gripping the end cover of the motor, then gripping the rotor of the motor, and finally completing the assembling of the rotor and the end cover of the motor, so that the problem of rotor displacement generated by magnetic force attraction with the inner wall of a stator in the process that the rotor of the permanent magnet synchronous motor is pressed is solved, and the problems that the end cover is deformed and the cooperation is non-uniform caused by knocking when the end cover of the permanent magnet synchronous motor is mounted are solved.

Description

Technical field [0001] The invention relates to tooling, in particular to an automatic assembly device for a rotor and an end cover of a permanent magnet synchronous motor. Background technique [0002] Because permanent magnet synchronous motors have the advantages of simple structure, small size, fast response, wide speed range, high power factor, etc., they have been increasingly used in the new energy automobile industry, and have been widely used with the rise of the new energy automobile industry. The application also puts forward requirements for the stability of permanent magnet motor operation and noise reduction. [0003] The installation of the rotor and end cover of the permanent magnet synchronous motor is a very important process in the motor assembly process. The existing assembly process uses a cylinder pressure rod to press the rotor into the housing assembly, and then the operator uses a hammer to hit the end cover , To complete the matching of the end cover with...

Problems solved by technology

[0003] The installation of the permanent magnet synchronous motor rotor and end cover is a very important process in the motor assembly process. The existing assembly process is to use the cylinder pressure rod to press the rotor into the casing assembly, and then the operator uses a hammer to hit the end cover , to complete the cooperation between the end cover and the bearing and the casing assembly. This operation method causes several problems: First, because the rotor is plugged with magnetic steel with magnetic force, during the process of pressing the rotor, it is attracted by the inner wall of the stator due to magnetic force. resulting in eccentricity

Second, because the installation of the end cover has two fits, the fit between the end cover bearing chamber and the bearing and the fit between the end cover seam and the casing assembly, it is not easy to install the end cover only by hammering, and the fit It is also uneven, and when the operator is screwing the screw, it often appears that the last screw is difficult to screw in.

The third is that the percussion of the hammer can easily deform the end cap

Due to the above problems, it is easy to cause vibration and abnormal noise when the motor rotates at high speed
