The second clamping member includes a slider 43, which is slidably arranged inside the slide groove 42. The outer surfaces of the four slides 21 are provided with movable grooves 24. The inner surfaces of the four movable grooves 24 are slidably connected with clamping plates 21. The lower surfaces of the four clamping plates 21 are fixedly connected with connecting blocks 1 44. The outer surface of the slider 43 is fixedly connected with four connecting blocks 2 45. A rotating plate 46 is rotatably connected between the connecting blocks 1 44 and 2 45 through a rotating shaft. The rotating plate 46 is movably arranged inside the movable groove 1 2. An installation groove 3 47 is provided inside the disassembly platform 1 below the slide groove 42. The inner bottom surface of the installation groove 3 47 is rotatably connected with a threaded rod 48. The threaded rod 48 is rotatably connected to the inner top surface of the slide groove 42, and the threaded rod 48 is threadedly connected to the slider 43. Inside the disassembly platform 1, a fourth mounting slot 5 is defined above the third mounting slot 47. A second motor 51 is fixedly connected to the inner bottom surface of the fourth mounting slot 5. The output end of the second motor 51 extends into the interior of the third mounting slot 47 and is fixedly connected to a second gear 52. The outer surface of the threaded rod 48, located within the third mounting slot 47, is fixedly connected to a third gear 53. Second gear 52 and third gear 53 are meshed and connected. Four mounting plates 11 are fixedly connected to the underside of the outer surface of the disassembly platform 1. Each of the four mounting plates 11 has mounting holes 12 defined on their outer surfaces.

[0044] Implementation process: Fix the device on the platform of the tire changer through the mounting hole 12, then place the tire on the upper surface of the disassembly table 1, and the motor 2 51 starts working to drive the gear 2 52 to rotate, thereby driving the gear 3 53 and the threaded rod 48 to rotate. The rotation of the threaded rod 48 drives the slider 43 and the connecting block 2 45 to slide downward inside the slide groove 42. The sliding of the connecting block 2 45 drives the rotating plate 46 to rotate. At the same time, the connecting block 1 44 drives the clamping plate 2 41 to slide inside the movable groove 2 4 toward the direction of the wheel hub, so that the four anti-slip pads 2 61 are in contact and fixed with the outer ring of the wheel hub. When the fixation needs to be released, the reverse operation can be performed.

[0045] Implementation benefits: The outer ring of the wheel hub is fixed.

[0046] Example 2

[0047] The first clamping member includes four slides 21, each of which slides inside the four movable slots 2. A clamping plate 22 is fixedly connected to the top surface of each of the four slides 21. A mounting slot 23 is defined on the upper side of the interior of the disassembly platform 1. A turntable 24 is rotatably connected to the inner surface of the mounting slot 23. Four arcuate slots 25 are defined on the outer surface of the turntable 24. Slide rods 26 are fixedly connected to one end of the lower surface of each of the four slides 21. The four slide rods 26 slide inside the four arcuate slots 25. A mounting slot 23 is defined within the disassembly platform 1, located below the mounting slot 23. A motor 31 is fixedly connected to the inner top surface of the mounting slot 23. The output end of the motor 31 extends into the interior of the mounting slot 23 and is fixedly connected to a gear 32. A tooth groove 33 is defined on the outer surface of the turntable 24. The gear 32 and the tooth groove 33 are meshed and connected. The protective member includes an anti-skid pad 1 6 and an anti-skid pad 2 61 . The anti-skid pad 1 6 is fixedly connected to the outer surface of the clamping plate 1 22 , and the anti-skid pad 2 61 is fixedly connected to the outer surface of the clamping plate 2 41 .

[0048] Implementation process: After the outer ring of the wheel hub is fixed, the motor 31 starts working to drive the gear 32 to rotate, thereby driving the turntable 24 to rotate. The rotation of the turntable 24 drives the slide bar 26 to slide inside the arc groove 25, while driving the four slide plates 21 and the clamping plate 22 to slide outward inside the movable groove 2, so that the four anti-slip pads 6 contact the inner ring of the wheel hub for fixation. The arrangement of the anti-slip pad 1 6 and the anti-slip pad 2 61 can not only prevent the wheel hub from wearing, but also prevent the wheel hub from loosening, thereby enhancing the fixing effect. When the fixation needs to be released, the reverse operation can be performed.

[0049] Implementation benefits: The inner ring of the wheel hub is fixed.
