The telescopic cylinder 16 consists of a cylinder body and a rod body with one end penetrating the cylinder body, and the rod body is located at The end of the cylinder body is provided with a limit block, which will not separate from the cylinder body. The extension and retraction of the telescopic cylinder 16 can realize the movement of the clamping wheel 15, which is convenient for clamping with the wheel spoke. The end of the telescopic cylinder 16 is fixedly installed with the clamping wheel 15, which is composed of a U-shaped mounting frame and a rotating wheel. The clamping wheel 15 is elastically connected to the translation plate 12 through a compression spring 14.

The side wall of the translation plate 12 is fixedly installed with a detection light 13, and the detection button 17 is electrically connected to the detection light 13;

[0025] The bottom of the shell 1 is rotatably connected with a turntable 2, and a pneumatic disk 5 is fixedly installed on the upper surface of the turntable 2. A clamping mechanism for clamping the wheel spoke is arranged on the pneumatic disk 5, and the clamping mechanism includes an air cavity 18 opened in the pneumatic disk 5, and an air inlet and an exhaust port are arranged on the air cavity 18. The air inlet is externally connected to an air pump for inflating to achieve the fixation of the wheel spoke, and the exhaust port is used for exhausting air to achieve the resetting of the piston rod 6 and release the restriction of the wheel spoke.

The cooperation of multiple clamping plates 4 clamps and fixes the spoke, and then the lifting cylinder 10 pushes the lifting plate 9 to move down, and the lifting plate 9 drives the driving motor 8 and the docking block 7 to move down. The docking block 7 is inserted into the rectangular docking hole to complete the docking.
