[0024] To make the above objects, features, and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation manners.

[0025] Refer to Figures 1 to 4 As shown, the present invention provides a clamping device for a wheel, including a support platform 1.

A plurality of sliding mechanisms are slidably provided on the support platform 1, and the sliding mechanisms slide in a direction close to or away from the support mechanism. A clamp is provided on the sliding mechanism for clamping the rim end face of the wheel.

[0026] In a further optimized solution, the support mechanism includes a connecting seat 11. The connecting seat 11 is fixedly connected to the top of the support platform 1. The connecting seat 11 is threadedly connected with a positioning mandrel 12. The positioning mandrel 12 is vertically arranged, and the positioning sleeve 13 is detachably connected to the top end of the positioning mandrel 12.

[0027] When positioning the inner side of the wheel 15, the cover stop of the wheel 15 is docked and positioned through the positioning sleeve 13. When positioning different wheels 15, according to the specific size of the wheel 15, the positioning mandrel 12 is rotated to adjust the different heights of the positioning sleeve 13 to ensure that the height of the positioning sleeve 13 matches the size of the wheel 15.

[0028] In a further optimized solution, the number of sliding mechanisms is four, and two of the sliding mechanisms are symmetrically arranged with respect to the support mechanism with the other two sliding mechanisms.

[0029] In a further optimized solution, a plurality of slide holes 4 are opened on the support platform 1. The sliding mechanisms correspond to the slide holes 4 one by one and are slidably arranged in the slide holes 4.

[0030] For a further optimized solution, the sliding mechanism includes a slider 5 which is slidably arranged in a sliding hole 4. A fixture is arranged on the slider 5, and a driving mechanism is also arranged on the slider 5. The driving mechanism is rotatably connected to the fixture.

[0031] For a further optimized solution, the fixture includes finger claws 7. One end of the finger claw 7 is rotatably connected to the driving mechanism.

[0033] When clamping the wheel 15, according to the outer diameter size of the wheel 15, the position of the slider 5 in the sliding hole 4 is adjusted. After adjustment, the telescopic end of the cylinder 6 extends, and drives the other end of the finger claw 7 to descend through the hinge action of the connecting rod 8, so that the outer side of the wheel 15 can be positioned by the nylon pad 9 and the support block 10.

[0034] For a further optimized solution, both ends at the bottom of the support platform 1 are respectively fixedly connected with support legs 2.
