Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of motor disassembly and separation equipment, in particular to a stator-rotor separation workbench. BACKGROUND

[0002] In the repair disassembly of the stator and rotor of the motor, the stator and rotor need to be positioned independently, and the relative movement of the stator and rotor is made from the axial direction to realize the disassembly and separation of the two.

[0003] At present, the stator-rotor disassembly and separation mechanism mostly adopts the mode of fixing the stator and moving the rotor assembly to separate the two, which has the following defects:

[0004] Firstly, it needs to use a C-shaped mechanism to clamp the upper and lower centers of the rotor, which requires a lot of force to clamp the rotor, has high precision and strength requirements for the structure, is bulky, and needs to overcome gravity to lift it up, so it cannot be simple and convenient, and the cost is high.

[0005] Secondly, since the magnetic attraction between the stator and rotor is very large, a lot of magnetic attraction needs to be overcome during the disassembly and separation of the stator and rotor, and since the C-shaped mechanism itself is bulky, a lot of lifting force is needed to lift the rotor together with the C-shaped mechanism, so manual speed reducer is generally needed to assist lifting during disassembly, which is high in use cost; and during the lifting of the C-shaped mechanism and the rotor, the C-shaped mechanism is bulky, which easily causes the clamped rotor to be radially offset from the stator, making the stator and rotor more likely to be attracted together and increasing the difficulty of disassembly, and the radial offset of the stator and rotor easily scratches each other, increasing the disassembly failure rate.

[0006] Thirdly, maintenance personnel need to regularly maintain the manual speed reducer, which affects subsequent disassembly work; at the same time, during the maintenance of the manual speed reducer, the bolts need to be disassembled and then the coaxiality and perpendicularity of the equipment are re-tightened, which consumes a lot of time, effort and manpower, and the efficiency is very low, and there is also the safety problem of missing bolts.

[0049] Then the stator clamping mechanism is started, the stator lifting plate 27 is pressed on the lifting slide 41 by two first pressing assemblies, so that the stator lifting plate 27 is fixed with the lifting slide 41. Then the rocker wheel 42 of the lifting driving mechanism is rotated, the lifting slide 41 is lowered, so that the stator lifting plate 27 fixed with the lifting slide 41 is lowered together, until the multiple clamping block assemblies 33 at the bottom of the stator lifting plate 27 are lowered to the flange 38 of the stator 51, at this time the mounting rod 34 is embedded into the screw through hole 39 of the flange 38 of the stator 51, each clamping block 35 is turned over, so that the clamping groove 37 of the clamping block 35 is clamped on the flange 38 of the stator 51, and then the locking of the clamping block 35 on the mounting rod 34 is realized through the locking structure 40, that is, the clamping of each clamping block assembly 33 on the stator 51 is completed.

The pressing plate 25 of each second pressing assembly 24 is opened, and the flywheel housing 2 is released.
