One end of the rotating shaft 2 is connected to the driving end of the corresponding rim clamping claw flipping driving component, and the clamping claw seat 3 is installed at the other end of the rotating shaft 2. The two clamping cylinders 4 are respectively rotatably installed at the two ends of the clamping claw seat 3 away from the rotating shaft 2. The outer periphery of the clamping cylinder 4 is provided with a bearing groove 5.

[0025] When the device is in use, first install the device on the frame (a connecting piece is installed on the top of the device, and the connecting piece can be connected to the frame), and then control the horizontal movement of the two sets of rim clamping arm assemblies through the rim centering and tightening driving components, so that the four clamping cylinders 4 clamp and fix the wheels, and each clamping cylinder 4 adopts a contoured structure (the design of the bearing groove 5), which can fit well with the wheel rim and will not contact other parts of the wheel, thereby greatly reducing the possibility of wheel damage. When flipping is required, the wheel can be flipped by rotating the two sets of rim clamping assemblies through the two sets of rim clamping claw flipping driving components.

[0026] In this embodiment, an anti-damage layer is provided on the outer side of the clamping tube 4, and the material of the anti-damage layer is brass. Brass is softer than the wheel tread, which can further effectively prevent the clamping point from causing damage to the wheel.
