A vertical assembly device for the same groove of the rotor magnets of the permanent magnet motor of the rail transit

Abstract

The invention discloses a vertical assembly device for magnetic steel with the same groove of the rotor of a permanent magnet motor for rail transit, which comprises a magnetic steel assembly guide die and an iron ring. The two sides of the slot are respectively provided with a first auxiliary slot and a second auxiliary slot, the first and second auxiliary slots are connected with the magnetic steel slot, the first auxiliary slot is provided with a first iron block, and the second auxiliary slot is arranged in A second iron block is provided, the widths of the first and second iron blocks in the circumferential direction are different, and the iron ring can be sleeved on the outer circumference of the rotor iron core and fixed with the rotor iron core. The invention combines the iron ring and the first iron block and the second iron block with different widths, so that the magnetic steel is adsorbed and stayed at a specific position under the action of unbalanced magnetic force, so that it can control the magnetic steel after each piece of magnetic steel is inserted into the rotor core. The initial position of the magnetic steel ensures that the adjacent two pieces of magnetic steel will not collide when they are assembled into the iron core, which solves the problem that the initial distance of the magnetic steel into the iron core slot is uncontrollable, causing the collision and damage of the adjacent two pieces of magnetic steel.

Description

technical field [0001] The invention relates to the technical field of manufacture of permanent magnet motors, in particular to a vertical assembly device of a permanent magnet motor rotor magnet steel in the same groove for rail transit. Background technique [0002] During the production process of the rotor of the permanent magnet motor, the main problem facing the assembly of samarium cobalt magnetic steel is that when the magnetic steel is assembled, two adjacent pieces of magnetic steel collide and are damaged. In order to improve the efficiency of the subway permanent magnet motor rotor magnetic steel assembly, the qualified rate of the magnetic steel assembly, and the consistency of the magnetic steel assembly quality, the overall structure of the subway permanent magnet traction motor rotor core is commonly used in the manual magnetic steel assembly scheme: same-slot assembly / same-slot assembly Pole assembly / same layer assembly, the efficiency of the three assembly ...

AI Technical Summary

Problems solved by technology

[0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art, to provide a method that can control the initial position of each piece of magnetic steel after it is inserted into the rotor core, and ensure that two adjacent pieces of magnetic steel will not collide when they are assembled into the iron core. Vertical assembly device for rail permanent magnet motor rotor magnets in the same slot, which solves the problem that the initial distance of the magnets into the rotor core slot is uncontrollable, causing damage to two adjacent pieces of magnets due to collision
