Fig. 1 is a schematic perspective view of an embodiment of the present utility model.

Detailed Description

Specific embodiments of the present utility model will be described below with reference to the accompanying drawings. As shown in fig. 1: the motor rotor centering dismounting device comprises a frame 1 as a foundation, a workbench 2 is arranged at the top of the frame 1, two slide rails 3 are symmetrically arranged on the workbench 2, a sliding platform 4 is connected onto the slide rails 3 in a sliding manner, the sliding platform 4 is connected with a tooling platform 5 through a locating pin, a plurality of tooling clamps 6 are arranged on the tooling platform 5, a quick clamp 7, a buffer 8 and a limiting block 9 which are matched with the sliding platform 4 are also arranged on the workbench 2,

The working process of the motor rotor centering dismounting device provided by the embodiment of the utility model is as follows: firstly, pulling out the sliding platform 4, enabling the sliding platform 4 to move from the lower part of the top plate 14 to the outer loading position, installing a tooling platform 5 on the sliding platform 4 by using a mechanism such as a locating pin, arranging corresponding tooling clamps 6 on the tooling platform 5 according to the specification and the model of a motor which is required to be disassembled and assembled, fixedly connecting the motor on the tooling platform 5 by using the tooling clamps, after the motor is fixed on the tooling platform 5, inserting the bottom end of a rotor part of the motor into a guide sleeve 25, pushing the sliding platform 4, the tooling platform 5 and the motor on the sliding platform back to the disassembling and assembling station together, wherein the motor is positioned under the top plate 14 at the moment, stopping moving after the sliding platform 4 contacts a limiting block 9, and limiting the sliding platform 4 by using a quick clamp 7;

the hydraulic cylinder 16 sends instructions to the hydraulic cylinder 16 through the control system, the hydraulic cylinder 16 drives the top plate 14 to ascend, and because the top plate 14 is connected with the bottom plate 15 through the four first guide posts 13, when the top plate 14 ascends, the frame formed by the top plate 14, the first guide posts 13 and the bottom plate 15 ascends integrally, so that the rotating shaft 24 supported on the bottom plate 15 and the lower center at the top end of the rotating shaft rotate to ascend relative to the motor until the lower center contacts with the bottom end of the rotor, at the moment, the rotor of the motor is clamped between the upper center 20 and the lower center,

then an operator drives the screw 17 to rotate through the hand wheel 18, the rotation of the screw 17 is finally converted into the longitudinal movement of the tip holder 19, and all the second guide posts 21 slide in the third guide sleeve 22 in the process of the movement of the tip holder 19 so as to ensure that the movement can be stably performed; the top bracket 19 drives the upper top 20 to move downwards until the upper top 20 contacts with the top end of the rotor part of the motor to be disassembled and assembled;

so far, the rotor part of the motor is clamped between the upper center 20 and the lower center, and the preparation work is completed;

then, the worker controls the hydraulic cylinder 16 to ascend through the control system again, the upper center 20 and the lower center drive the rotor part to ascend together, but the rotor part ascends relative to the stator part due to the fact that the shell (namely the stator part) of the motor is still fixed on the tooling platform 5, so that the rotor part is pulled out of the shell of the motor, and the motor rotor is detached;

when the motor rotor is required to be installed, only the motor shell is required to be installed on the tooling platform 5, then the hydraulic cylinder 16 is controlled to drive the top plate 14 to ascend, the lower tip penetrates out of the guide sleeve 25 until the lower tip moves to the upper side of the motor shell, then the motor rotor is clamped by the upper tip 20 and the lower tip, finally the hydraulic cylinder 16 is controlled to recover, the upper tip 20 and the lower tip drive the rotor to descend relative to the motor shell, and the installation of the rotor is completed.
