Glue filling equipment for rotor magnetic steel

Abstract

The invention discloses glue filling equipment for rotor magnetic steel. The glue filling equipment comprises a base, a fixing ring, a glue port plate, a flow channel plate and a covering plate; the fixing ring is used for fixing magnetic steel and placed on the base together with the magnetic steel; the fixing ring is covered with the glue port plate, and a plurality of penetrating first throughholes are formed in the glue port plate; the glue port plate is covered with the flow channel plate, a plurality of flow channels are formed on the flow channel plate, second through holes are formedin the tail ends of the flow channels, and the positions of the second through holes correspond to the positions of the first through holes; the glue port plate is covered with the covering plate, anda glue injection hole which communicates with the flow channels is formed in the covering plate. According to the glue filling equipment for the rotor magnetic steel, the glue port plate is matched with the flow channel plate, the periphery of the magnetic steel is subjected to glue filling in a targeted mode, glue flows to an appointed position of the glue port plate on the periphery of the magnetic steel along the flow channel plate, the operation is easy and convenient, additional treatment is not needed, the glue filing efficiency is improved, and the using cost of the glue is reduced.

Description

technical field [0001] The invention relates to a rotor magnetic steel glue filling equipment. Background technique [0002] In today's society, new energy vehicles are developing rapidly, among which pure electric vehicles and hybrid vehicles are the two major directions for the development of new energy vehicles. The application of motors in new energy vehicles is also becoming more and more mature. At present, the electric drive part of the hybrid vehicle mainly uses the permanent magnet synchronous motor as the power source. In the manufacturing process of this kind of motor, the manufacturing process of the permanent magnet motor rotor is very important. [0003] The permanent magnet rotor of the motor needs to insert the magnetic steel into the iron core slot. In order to prevent the magnetic steel from falling off, it needs to be filled with glue to fix the magnetic steel. It is necessary to control the temperature, time and pressure through the equipment, and use th...

AI Technical Summary

Problems solved by technology

[0004] At present, there is no special tooling for glue filling, and it is necessary to coat a large amount of glue on the outer ring of the overall magnetic steel before trimming. This method is cumbersome and wastes glue, and the subsequent processing is complicated.
