[0005] The beneficial effects of the utility model are as follows: the device has the function of automatically disassembling the iron core, which saves manpower.

At the same time, the inner support rod can be quickly adjusted according to the inner diameter of the stator core, and the bottom support plate can automatically buckle and fix the bottom of the stator core after the inner support rod is inserted into place, and at the same time it also serves as a reminder that the insertion is in place, and can automatically transfer and place the stator core removed from the motor, which greatly facilitates the disassembly and maintenance of the stator core.
[0006] In order to stably separate the stator core from the motor housing:
[0007] As a further improvement of the above technical solution: the clamp includes a mounting plate installed on the top of the machine platform, a cylinder is installed on the side of the mounting plate, and a piston rod of the cylinder is connected to the clamping plate.
[0008] The beneficial effect of this improvement is: the motor end cover and rotor with the iron core to be removed are removed and placed on the machine table with the mouth facing upward, and the cylinder is controlled to drive the clamping plate to move to clamp the motor.

[0027] The inner support rod 23 and the bottom support plate 24 of the device can be suitable for stator cores of different sizes and specifications. At the same time, the inner support rod 23 can be quickly adjusted according to the inner diameter of the stator core, and the bottom support plate 24 can automatically buckle and fix the bottom of the stator core after the inner support rod 23 is inserted into place, and it also serves as a reminder that the insertion is in place, and can automatically transfer and place the stator core removed from the motor, which greatly facilitates the disassembly and maintenance of the stator core.
[0028] The clamp 2 includes a mounting plate 3 mounted on the top of the machine platform 1 , a cylinder 4 is mounted on the side of the mounting plate 3 , and a piston rod of the cylinder 4 is connected to a clamping plate 5 .
[0029] After the motor end cover and rotor with the core to be removed are removed, they are placed on the machine table 1 with the mouth facing upwards, and the cylinder 4 is controlled to drive the clamping plate 5 to move to clamp the motor. Since the motor housing is clamped by the clamping plate 5, the stator core can be stably separated from the motor housing.
[0030] The inner support fixing structure includes a first rotating connecting seat 20 installed on the outside of the sliding sleeve 18 and the fixed sleeve 19. The first rotating connecting seat 20 is rotatably connected to the rotating arm 21. The other end of the rotating arm 21 is rotatably connected to the second rotating connecting seat 22. The side surface of the second rotating connecting seat 22 is connected to the inner support rod 23. The bottom of the inner support rod 23 is provided with an integrally formed bottom support plate 24.
[0031] The inner support rod 23 is squeezed to drive the rotating arm 21 to rotate, thereby pushing the sliding sleeve 18 to rise. While the inner support rods 23 are brought close to each other, the spring 25 is compressed. After the inner support rods 23 are squeezed close to each other, they can be inserted into the interior of the stator core. When the inner support rod 23 is inserted into the interior of the stator core, you can let go. Through the elastic force of the spring 25, the inner support rod 23 keeps in contact with the inner side of the stator core, and after the bottom support plate 24 moves to a height below the bottom of the stator core, the bottom support plate 24 is automatically buckled into the bottom of the stator core through the elastic force of the spring 25. At this time, the screw motor 10 can be controlled to run in reverse, driving the screw 11 and the core fixing mechanism mounting plate 12 to lift upward, thereby driving the stator core to lift upward.
[0032] The bottom of the bottom supporting plate 24 is an inclined surface, and one end of the bottom supporting plate 24 is a rounded shape.
[0033] The bottom of the bottom support plate 24 is an inclined surface, which is convenient for sliding from the top inner edge of the stator core into the inner side of the stator core. One end of the bottom support plate 24 is a rounded shape to prevent the bottom support plate 24 from scratching the coil when sliding inside the stator core.
[0034] The slider 14 is inserted into and slidably connected to the lifting guide rail 8 .
[0035] The slider 14 is inserted into and slidably connected to the lifting guide rail 8 to play a limiting role, thereby preventing the screw rod 11 from rotating as the screw motor 10 runs.
[0036] Working principle and use process of the utility model: When the device is used, the end cover and rotor of the motor whose core is to be taken out are removed and placed on the machine table 1 with the mouth facing upward, and the cylinder 4 is controlled to drive the clamping plate 5 to move to clamp the motor, and then the screw motor 10 is controlled to operate. The operation of the screw motor 10 and the transmission of the screw 11 drive the screw 11 together with the core fixing mechanism mounting plate 12 to descend through the guiding effect of the slider 14 and the lifting guide rail 8. The slider 14 and the lifting guide rail 8 are slidably connected to play a limiting role to prevent the screw 11 from rotating with the operation of the screw motor 10. As the core fixing mechanism mounting plate 12 descends, the inner support rod 23 gradually When the inner support rod 23 is close to the motor, the inner support rod 23 is squeezed to drive the rotating arm 21 to rotate, thereby pushing the sliding sleeve 18 to rise. While the inner support rods 23 are brought close to each other, the spring 25 is compressed. After the inner support rods 23 are squeezed close to each other, they can be inserted into the interior of the stator core. When the inner support rod 23 is inserted into the interior of the stator core, you can let go. Through the elastic force of the spring 25, the inner support rod 23 keeps in contact with the inner side of the stator core, and after the bottom support plate 24 moves to a height below the bottom of the stator core, through the elastic force of the spring 25 rebounding, the bottom support plate 24 automatically buckles into the bottom of the stator core. At this time, the screw motor 10 can be controlled to run in the reverse direction, driving the screw rod 11 together with the core The fixing mechanism mounting plate 12 is lifted upward, thereby driving the stator core to be lifted upward. Since the motor housing is clamped by the clamping plate 5, the stator core can be stably separated from the motor housing, and since the inner support rod 23 can be adjusted, the device can also be applied to the removal of the stator core of motors of different sizes. After the stator core is separated from the motor, the motor 7 can be controlled to drive the lifting guide rail 8 to rotate and then drive the removed stator core to move away from directly above the motor. After the lifting guide rail 8 rotates 180 degrees, the screw motor 10 can be controlled to drive the screw 11, the core fixing mechanism mounting plate 12 and the stator core to descend, and the manual pressure is pressed. The inner support rod 23 allows the bottom support plate 24 to leave the support on the bottom of the stator core, so that the stator core can be placed on the top of the machine table 1, which is convenient for the subsequent inspection and maintenance of the stator core. In summary, the inner support rod 23 and the bottom support plate 24 of the device can be suitable for stator cores of different sizes and specifications, and the inner support rod 23 can be quickly adjusted according to the inner diameter of the stator core. The bottom support plate 24 can automatically buckle and fix the bottom of the stator core after the inner support rod 23 is inserted into place, and it also serves as a reminder that the insertion is in place, and can automatically transfer and place the stator core removed from the motor, which greatly facilitates the disassembly and maintenance of the stator core.
