[0024] Combination Figure 1-5 As shown, a tire and wheel hub separation device comprises:

[0025] The base 1 is the installation base of the entire splitting device, and is a cylindrical structure with a bearing seat 11 on the top;

[0026] The mounting platform 2 is composed of an upper and lower part, which can be adjusted up and down, and its bottom is connected to the bearing seat 11 on the base 1, and can be flexibly rotated;

[0027] The connecting arm 3 is detachably fixedly connected to the upper half 21 of the mounting platform 2;

[0028] The stripping piece 4 is detachably fixedly mounted on the end of the connecting arm 3, and is inserted between the wheel hub and the tire by cooperating with the rotation and lifting effect of the base 1 and the mounting platform 2, thereby realizing the separation of the wheel hub and the tire;

[0029] The clamping assembly 5 is arranged at the bottom of the base 1 to clamp and fix the center of the hub, thereby ensuring the stability of the entire device.

[0030] Specifically, in order to drive the mounting table 2 to rotate, a driving motor should be arranged inside the base 1 as a power source, and a control button for controlling the driving motor should be arranged on the side wall of the base 1. At the same time, the driving motor is embedded in the base 1, and the output end at the top should be vertically facing upward and fixedly connected to the center of the bottom surface of the mounting table 2.

[0031] The mounting platform 2 adopts a combined structure, that is, it is composed of an upper half 21 and a lower half 22, wherein an electric telescopic rod 23 is embedded in the interior of the lower half 22, and a connecting end is provided at the top of the electric telescopic rod 23, so that it is fixedly connected to the center of the bottom surface of the upper half 21, and a control button for controlling the electric telescopic rod 23 should also be provided on the outer side wall of the lower half 22 of the mounting platform 2 to control its lifting height.

[0032] A pin hole 24 is also provided on the top side wall of the upper half 21, and the connecting arm 3 is slidably inserted into the pin hole 24. At the same time, a positioning hole 25 of the same size as that on the surface of the connecting arm 3 is provided at the center of the top surface of the upper half 21. The two are locked and fixed with pins or bolts. Therefore, based on this structure, the connecting arm 3 can be lengthened to adjust the length that its end can extend, so that it can be used for tires and wheels of various specifications and sizes.

[0033] The stripping piece 4 is divided into two parts, a connecting rod at the top and a conical plug-in block 41 at the bottom, wherein a threaded section is provided on the top side wall of the connecting rod, and the threaded section is locked and fixed to the end of the connecting arm 3 by a nut, and the inner part of the conical plug-in block 41 at the bottom is hollow, and a rectangular opening is provided on the back, and a clamping plate 42 is movably installed inside the rectangular opening, and the top of the clamping plate 42 is arc-shaped and extends toward both ends to form connecting ends, and the connecting end is movably connected to the inner wall of the conical plug-in block 41, so that the clamping plate 42 can be flipped outward to be horizontal, and can also be flipped inward and retracted to the inside of the rectangular opening to make it flush with the back of the conical plug-in block 41.

[0034] A micro motor 43 is also provided inside the conical plug block 41. The micro motor 43 is arranged vertically downward so that its output end is close to the connection end on the side of the card plate 42, and the two are combined with mutually compatible bevel gears to form a driving structure. The wire of the motor is vertically upward through the top end of the connecting rod of the stripping member 4. On the basis of this structure, a control button can be set on the top end face of the stripping member 4 to facilitate its control and adjustment.

[0035] The clamping assembly 5 includes a locking plate 51 movably mounted inside the base 1, and a spiral-shaped limiting groove 52 is provided on the locking plate 51. A positioning plate is fixedly mounted on the bottom surface of the base 1, and three slide grooves 53 are provided on the positioning plate. The three slide grooves 53 are arranged in a circular array with the center of the positioning plate, and a clamping block 54 is movably mounted inside each slide groove 53. The top part of the clamping block 54 extends upward and is slidably inserted into the limiting groove 52. The entire structure is combined to be similar to a three-jaw chuck structure, so it can be firmly clamped at the center of the wheel hub to be locked and fixed to the wheel hub.

[0036] At the same time, in order to drive the above structure for clamping and ensure that it can self-lock, a servo motor 55 should be arranged inside the base 1, and a worm 57 should be connected to the output end of the servo motor 55, and the other end of the worm 57 is connected to the inside of the base 1 for transmission. At the same time, a worm wheel 56 is arranged on the top surface of the locking plate 51, and the worm 57 and the worm wheel 56 are meshed with each other.

[0037] In the above structure, since the base 1 is supported and fixed based on the wheel hub, in actual use, the wheel hub should be placed on a relatively flat bottom surface or a workbench.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solution recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
