Device for assembling built-in rotor permanent magnets of permanent magnet motor with long iron core

Abstract

The invention relates to a device for assembling built-in rotor permanent magnets of a permanent magnet motor with a long iron core. The device comprises a permanent magnet tool groove, a push plate,an ejector block, an oil hydraulic cylinder and a wooden support. The permanent magnet tool groove is formed in the wooden support. The front end of the permanent magnet tool groove is arranged on anassembling end face of a rotor. The push plate is arranged in the permanent magnet tool groove, and is connected with the permanent magnet tool groove in a sliding manner. The rear end of the push plate is in contact connection with the front end of an ejector block arranged in the permanent magnet tool groove, the rear end of the ejector block is connected with the oil hydraulic cylinder, and theoil hydraulic cylinder drives the push plate through the ejector block to push permanent magnets placed in the front portion of the permanent magnet tool groove into an iron core of the rotor along the permanent magnet tool groove. The push plate is pushed through the oil hydraulic cylinder to install the permanent magnets, repulsive force between the permanent magnets is easily overcome, and whole assembly is achieved. Because of the permanent magnet tool groove, the permanent magnets can be conveniently stored and directionally pushed, and a guiding effect on assembly of the permanent magnets is achieved.

Description

technical field [0001] The invention relates to an assembly device, in particular to a device for assembling a permanent magnet of a built-in rotor of a long iron core permanent magnet motor. Background technique [0002] When assembling the permanent magnet of the built-in rotor of the long-core permanent magnet motor, the existing method of manually holding the magnetic steel for assembly cannot guarantee the accuracy of the assembly when assembling the permanent magnet far from the assembly end, and there are also problems. greater safety hazard. At the same time, the magnetic steel used in large and medium-sized high-speed permanent magnet motors is relatively large, and the magnetic force between the permanent magnet and the permanent magnet and the ferromagnetic material is relatively large. The permanent magnet is easily broken during assembly, and the labor intensity of the assembly operator is relatively high. It is necessary to specially design the permanent magne...

[0002] When assembling the permanent magnet of the built-in rotor of the long-core permanent magnet motor, the existing method of manually holding the magnetic steel for assembly cannot guarantee the accuracy of the assembly when assembling the permanent magnet far from the assembly end, and there are also problems. Bigger security risk

At the same time, the magnetic steel used in large and medium-sized high-speed permanent magnet motors is relatively large, and the magnetic force between the permanent magnet and the permanent magnet and the ferromagnetic material is relatively large. The permanent magnet is easily broken during assembly, and the labor intensity of the assembly operator is relatively high. It is necessary to specially design the permanent magnet assembly device for the built-in rotor of long iron core permanent magnet motors to ensure accurate, safe and efficient assembly of permanent magnets
