Description
Technical Field
The invention relates to an assembly technology of a permanent magnet synchronous traction motor for rail transit, in particular to a device and a method for assembling magnetic steel of a rotor of the permanent magnet synchronous traction motor for rail transit.
Background
The rail transit permanent magnet synchronous traction motor meets the current situation requirements of environmental protection and energy conservation, the application prospect is more and more clear, and the application is expected to be more and more popularized, so the requirement of industrial production of rail transit permanent magnet synchronous traction motor manufacturing is urgent, the automation of magnetic steel assembly in permanent magnet rotor manufacturing is one of key process technologies, and the development of magnetic steel assembly equipment suitable for the rail transit permanent magnet synchronous traction motor becomes the urgent need of technicians in the field.
The structure of the rotor core without the magnetic steel is shown in the attached drawing 1, and the permanent magnet rotor formed after the rotor core is assembled with the magnetic steel is shown in the attached drawings 2 and 3. The magnet steel material is neodymium iron boron and samarium cobalt generally, and if the magnet steel is samarium cobalt material, has certain compressive strength, but can not bear the impact force. Because the magnet steel is generally in a magnetizing state before being assembled, certain magnetic attraction force exists between the magnet steel and the magnetic conductive material in contact with the magnet steel during the assembling process, the influence of the magnetic attraction force needs to be overcome, and the magnet steel is ensured not to be damaged. The magnetic steel and the iron core slot (or called magnetic steel assembling slot) are in clearance fit, the magnetic steel has polarity distribution in the iron core, two slots form one group to form one magnetic pole, the magnetic poles N, S are distributed around the rotating shaft at intervals, and the initial position of each motor magnetic pole is the same.
The rotor core structure of the conventional permanent magnet motor is greatly different from the permanent magnet rotor of the rail transit permanent magnet synchronous traction motor, the assembly process flow is also greatly different, the rotor core of the conventional permanent magnet motor is divided into multiple sections, the rotor is assembled with a rotating shaft after single-section assembly magnetic steel is packaged to form the rotor, the volume and the weight of the rotor of the rail transit permanent magnet synchronous traction motor are large, the structure that the whole iron core is provided with the rotating shaft is generally adopted before the rotor magnetic steel is assembled, one end of an iron core groove is shielded by an end plate, and the iron core at the assembly end is in a free state and has a spring-. The main differences between the single-section iron core assembly magnetic steel and the rotor iron core assembly magnetic steel with the shaft are as follows: the iron cores are positioned differently, the single-section rotor iron core is centered by the shaft hole and is oriented by the iron core slot, while the rotor with the shaft is centered by the shaft, and the orientation by the iron core slot is difficult and needs to convert the positioning reference for many times; the layers of the magnetic steel are different: the number of layers of the magnetic steel to be assembled on the single-section rotor core is 1-3, the magnetic steel can be assembled in place after one-time assembly, the magnetic steel is assembled on the rotor with the shaft by a plurality of layers of reciprocating assembly and press mounting, and the press mounting stroke is large and variable; the iron cores have different weights: the single-section rotor core has small mass, the upper station and the lower station are convenient, the rotor core with the shaft has large mass, and the upper station and the lower station are difficult. Due to the differences in the aspects, the magnetic steel assembling equipment of the conventional permanent magnet motor cannot be applied to the assembling process of the permanent magnet rotor of the rail transit permanent magnet synchronous traction motor, the magnetic steel is generally assembled by a guide die manually at present, the guide die is fixed after being aligned with the rotor core slot, the magnetic steel is assembled by manually dividing the slot to ensure that the magnetic steel assembling polarity is correct, but the phenomenon of samarium-cobalt magnetic steel breakage is easy to occur, and the assembling efficiency is low; if the magnetic steel is manually assembled by adopting a same-layer assembly method, the problem that the samarium-cobalt magnetic steel is damaged can be solved, but the assembly polarity is easy to make mistakes.
