[0049] Install the motor 1, separate the two sliding wheels 76 of the movable end 73 of the moving trolley 7 from one of the movable guide rails 6, and rotate the movable end 73 of the moving trolley 7 so that it folds onto the other movable guide rail 6. Raise the third lifting screw 5 to disengage the support wheels 622 of the sliding rails 62 of the two movable guide rails 6 from the second guide rail transverse platform 4. Push one end of the sliding rail 62 of the two movable guide rails 6, causing it to rotate about the rotation axis. The space between the two movable guide rails 6 is now open, and the motor 1 is moved to the boss 91 of the workbench 9. After the jacking is completed, the jacking rod 8 is tightened, and the jacking rod 8 is tightened, so that the jacking rod 8 is tightened and the jacking rod 8 is tightened.

[0050] To remove the rotor 11, first simultaneously adjust the first and second lifting screws 21, 22 to raise and lower the lifting platform 2, thereby raising and lowering one end of the rotor 11 of the motor 1. Rotate the adjusting nut 714 on the hook 71 to raise and lower the other end of the rotor 11, thereby adjusting the vertical position of the rotor 11 of the motor 1 and disengaging the rotor 11 from the stator 12. Rotate the ejection screw 8 to push the rotor 11 out of the stator 12.

[0051] The rotor 11 is transferred, and the moving end 73 of the moving trolley 7 is taken out from the movable clamp of the sliding guide rail 62, and the moving end 73 of the moving trolley 7 is rotated so that the moving end 73 of the moving trolley 7 is folded on the other moving guide rail 6. The third lifting screw 5 is adjusted to rise, so that the support wheels 622 of the sliding guide rails 62 of the two moving guide rails 6 are separated from the second guide rail transverse platform 4, and one end of the sliding guide rails 62 of the two moving guide rails 6 is pushed to open to both sides (such as Figure 11 The first positioning pin 623 passes through the first pin hole and the second pin hole to position the upper section 612 and the lower section 613, restricting the rotation of the movable guide rail 6, and then moving the rotor 11.

[0052] The rotor 11 is installed in reverse operation.

[0053] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0054] A frame-type motor 1 rotor 11 disassembly and assembly device includes a workbench 9, a first lifting screw 21, a second lifting screw 22, two guide rods 24, a lifting platform 2, a movable guide rail 6, a movable trolley 7, a hook 71, and a top-taking screw 8. The motor 1 is placed on the workbench 9. The device can adjust the height of the rotor 11 by raising and lowering the lifting platform 2 and the lifting and lowering rod 713 of the hook 71. The guide rail transverse screw 52 adjusts the distance between the two movable guide rails 6, thereby adjusting the telescopic amount of the movable trolley 7 to accommodate motors 1 of different specifications. The rotor is disassembled by the top-taking screw 8, so that the height and level of the rotor 11 of the motor 1 can be well maintained during the disassembly process, thereby preventing the rotor 11 from scratching the coils inside the stator 12. The technical solution of the present invention is easy to install, reduces the difficulty of operation, improves work efficiency, and greatly reduces the time and work intensity of replacing the rotor 11.
