[0019] The gear disassembly device for the Lenze motor includes a guide support 1, an impact hammer 10, a lifting platform 3, a support frame 5, an extrusion gear ring 6, a pushing rack 8 and a pushing hydraulic cylinder 7 (see the attached Figure 1 ) of the specification.

[0020] The lifting platform 3 is installed on the guide support 1 through the guide rod 2; a lifting oil cylinder 4 is installed below the lifting platform 3; the lifting oil cylinder 4 is connected to the lifting platform 3. When the lifting oil cylinder 4 works, it can drive the lifting platform 3 to move up and down.

[0021] One end of the lifting platform 3 is hinged with a feeding plate 13; support rollers 14 are installed at the lower end of the feeding plate 13 (see the attachedFigure 1 ). The supporting roller 14 is in rolling connection with the ground. During operation, the workpiece can be pushed onto the lifting platform 3 through the loading plate 13.

[0022] One side of the lifting platform 3 is equipped with an extrusion gear ring 6 through a support frame 5; on the support frame 5 above the extrusion gear ring 6, a push rack 8 is installed through a push hydraulic cylinder 7; the push rack 8 is in meshing connection with the extrusion gear ring 6. When the push hydraulic cylinder 7 drives the push rack 8 to move back and forth, the push rack 8 can drive the extrusion gear ring 6 to rotate.

[0023] On the support frame 5 inside the extrusion gear ring 6, a plurality of impact hammers 10 are installed in a divergent shape through guide blocks 9 (see the attached Figure 4 ).

[0024] The impact hammer 10 includes a sliding pin 16, a pressure-receiving block 17, and an impact rod 18; the sliding pin 16 is slidably installed on the guide block 9; the pressure-receiving block 17 is installed at the upper end of the sliding pin 16; the impact rod 18 is installed at the lower end of the sliding pin 16. A return spring 11 is installed on the sliding pin 16 of the impact hammer 10 above the guide block 9.

[0025] During operation, when the impact hammer 10 is pressed and moves inward, it will quickly reset under the action of the elastic force of the return spring 11.

[0026] A through hole 12 is provided on the support frame 5 inside the impact hammer 10 (see the attached Figure 2 ). During operation, the Lenze motor to be disassembled will pass through the through hole 12, and its gear will correspond to the impact hammer 10.

[0027] A plurality of arc-shaped extrusion blocks 15 are provided on the inner ring of the extrusion gear ring 6; the arc-shaped extrusion blocks 15 are in sliding contact connection with the corresponding impact hammers 10. An extrusion inclined surface 19 is provided on the bottom side of the impact rod 18; a pressure-receiving arc surface 20 is provided at the upper end of the pressure-receiving block 17 (see the attached Figure 3 ).

[0028] When the extrusion gear ring 6 rotates clockwise, it will squeeze the impact hammer 10 through the arc-shaped extrusion block 15 and the pressure-receiving arc surface 20 to make the impact hammer 10 move inward.

[0029] One side of the support frame 5 is equipped with a positioning center point 22 through a sliding bracket 21. The positioning center point 22 corresponds to the center point of the through hole 12. During operation, pushing the sliding bracket 21 can drive the positioning center point 22 to move back and forth.

[0030] For the gear disassembly device of the Lenze motor, during operation, first push the workpiece onto the lifting platform 3 through the loading plate 13, and then push the sliding bracket 21 to insert the positioning center point 22 into the inside of the through hole 12.

[0031] After the positioning center point 22 is inserted into the inside of the through hole 12, the height of the lifting platform 3 is adjusted by the lifting oil cylinder 4 so that the center of the motor shaft of the workpiece corresponds to the positioning center point 22. Subsequently, the workpiece is moved so that the center of its motor shaft contacts the positioning center point 22, and the workpiece and the positioning center point 22 are on the same straight line. Subsequently, the workpiece is pushed so that after it passes through the through hole 12, the position between the inner side of its gear and the workpiece socket corresponds to the impact rod 18 of the impact hammer 10.

[0032] After the above work is completed, the hydraulic cylinder 7 is pushed to drive the push rack 8 to move; during the movement of the push rack 8, the extrusion gear ring 6 is pushed to rotate clockwise. During the clockwise rotation of the extrusion gear ring 6, the impact hammer 10 will be extruded through the arc-shaped extrusion block 15 and the pressure receiving arc surface 20, causing the impact hammer 10 to move inward. During the inward movement of the impact hammer 10, it is inserted between the inner side of the gear of the workpiece and the workpiece socket through the extrusion inclined surface 19, and finally, by the way of extrusion and expansion, the gear is disassembled from the Lenze motor.

[0033] Subsequently, the hydraulic cylinder 7 is pushed to drive the push rack 8 to reset. During this process, the impact hammer 10 will be reset under the action of the reset spring 11. During the reset process of the impact hammer 10, the extrusion gear ring 6 will be pushed to reset through the arc-shaped extrusion block 15. So far, the gear disassembly device of the Lenze motor has completed all the gear disassembly work, and the disassembly device can enter the next working cycle.

[0034] The gear disassembly device of the Lenze motor has a compact structure and ingenious design, and can adapt to the disassembly work of gears of different models of Lenze motors, thus solving the problem that the existing disassembly tools can only disassemble the gears of a single model of Lenze motor, and is particularly suitable for the needs of disassembling the gears of Lenze motors.
