Description

Motor rotor dismouting workstation

Technical Field

The utility model relates to a motor dismouting equipment field, concretely relates to electric motor rotor dismouting workstation.

Background

The motor mainly comprises a stator, a rotor and other accessories (such as a shell, an end cover, a bearing, a fan and the like); the stator comprises a stator core and a stator winding; the stator core is generally formed by punching and laminating silicon steel sheets with the thickness of 0.35-0.5 mm and insulating layers on the surfaces, and uniformly distributed grooves are punched in the inner circle of the stator core and used for embedding stator windings; the insulating layer covers the whole stator core and the stator winding, and whether the insulating layer is complete or not directly determines the service life of the motor. The rotor is made of the same material as the stator and is formed by punching and laminating silicon steel sheets with the thickness of 0.5 mm, holes which are uniformly distributed are punched on the outer circle of the silicon steel sheets and used for arranging a rotor winding, and an insulating layer is also arranged on the surface of the whole rotor; therefore, the rotor and the stator of the motor need to be aligned very accurately when being installed, and the insulating layer is prevented from being damaged by collision and extrusion between the rotor and the stator.

For a motor maintenance factory, maintenance means that a stator and a rotor of a motor need to be separated and assembled, and the separation is to take the rotor down for maintenance; the assembly is to reassemble the repaired motor. The motor is in the dismouting in-process, and what need paying particular attention to in addition can not damage the silicon steel sheet and cover the insulating layer on the silicon steel sheet, otherwise can cause the secret injury for the motor, and the motor probably appears vibrating too big or the serious problem that generates heat when using, can seriously influence the life of motor finally. At present, for a maintenance factory, the motor rotor can be smoothly disassembled, but when the motor rotor is reassembled, the rotor is generally hoisted through an electric hoist and then inserted into a stator, alignment equipment is not arranged between the rotor and the stator in the inserting and assembling process, the axial direction of the stator is not parallel to the axial direction of the rotor, the stator can collide with the rotor when the motor rotor is installed, a light person knocks off an insulating layer, a heavy person knocks and loses a silicon steel sheet, a technician can only adjust the position of the rotor for multiple times by carefully taking the wing to perform position adjustment, but the problem is still difficult to avoid, the installation is time-consuming, and particularly for the motor maintenance factory, the construction period is seriously slowed down.
