DETAILED DESCRIPTION

[0012] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0013] The top of described sliding plate 4 is fixed with a clamping plate 5, and the top of inner cavity of rotating plate 2 is fixed with a rotating shaft 6. The outer wall of rotating shaft 6 is provided with a worm gear 7 that is rotated. The inside of worm gear 7 is provided with an arc groove 8 corresponding to slide rod 4, and the bottom end of slide rod 4 is fixed with a slider 9. The slider 9 is slidably connected with the corresponding arc groove 8. The rotating worm gear 7 can drive the clamping plate 5 to move horizontally through the sliding connection of arc groove 8 and slider 9, so that the four clamping plates 5 can move synchronously. The side wall of rotating plate 2 is integrally formed with a shell 10. The inside of shell 10 is provided with a worm 11 for rotation. The worm 11 is meshed with worm gear 7. The staff can drive the worm gear 7 to rotate and lock it by driving the worm 11.

[0014] Specifically, the splint 5 is designed in a V-shape, and a rubber pad is fixedly provided on the clamping surface of the splint 5. This design prevents the splint 5 from causing damage to the wheel hub when locking and fixing the wheel hub. A limit plate 12 is fixedly provided on the outer wall of the slide rod 4 between the turntable 2 and the worm gear 7. The limit plate 12 is fitted with the turntable 2. This design can prevent the slide rod 4 from moving longitudinally.

[0015] Specifically, the rotating shaft 6 is rotatably arranged inside the mounting plate 1, and a driving motor 13 and a reducer 14 are installed at the bottom of the mounting plate 1. The output end of the driving motor 13 is fixedly connected to the input end of the reducer 14, and the output end of the reducer 14 is fixedly connected to the bottom end of the rotating shaft 6. This design can reduce the output speed of the driving motor 13 through the reducer 14, so that the turntable 2 and the wheel hub can be rotated and adjusted synchronously.

[0016] Specifically, connecting plates 15 are fixedly provided on both sides of the bottom of the mounting plate 1, and mounting seats 16 are rotatably provided on the axial ends of the connecting plates 15. An adjusting motor 17 is installed on one side of one of the mounting seats 16, and the output end of the adjusting motor 17 is fixedly connected to one of the axial ends of the corresponding connecting plate 15. This design can control the angle of the turntable 2 by adjusting the motor 17, so that the turntable 2 can fit with the wheel hub, which is convenient for locking and fixing the wheel hub.

[0017] According to the personnel in this field, all electrical components and parts in this case are universal standard parts or parts known to technical personnel in this field. Their structures and principles can be known to technical personnel through technical manuals or through conventional experimental methods. The models are compatible with this solution and can operate normally. All electrical components in this case are connected to their compatible power supplies through wires, and according to actual conditions, appropriate controllers are selected to meet control requirements. The specific connection and control sequence should refer to the following working principle. The electrical connection is completed in the order of working between the electrical components. The detailed connection means are well known in this field and will not be explained in detail for electrical control.

[0018] Working Principle: To use the disassembler, a worker secures the mounting base 16 to the disassembler with bolts and then activates the adjustment motor 17. This motor, through the connecting plate 15, drives the turntable 2 to adjust its angle, thereby aligning the turntable 2 with the wheel hub. To secure the wheel hub, the user rotates the worm 11 with a handle. The rotating worm 11 rotates the worm wheel 7. Because the arcuate slot 8 is tilted, the arcuate slot 8, through its sliding connection with the slider 9, drives the slide bar 4 toward the wheel hub. This allows the four clamping plates 5 to simultaneously move toward the wheel hub. When the clamping plates 5 press against the wheel hub, the wheel hub is fixed in the center of the turntable 2. The V-shaped clamping plates 5 have four clamping points, providing eight points of contact with the wheel hub, ensuring proper centering. To rotate the turntable 2, a worker activates the drive motor 13. The drive motor 13 reduces the output speed of the countershaft 6 via the reducer 14, which then drives the turntable 2 and wheel hub for rotational adjustment.

In particular, the various technical features described in the various embodiments may be combined in any manner as long as there are no structural conflicts.
