[0002] The rubber tire inspection clamping device is a device used to fix and clamp the rubber tire so as to perform various inspections and tests.

[0003] A Chinese utility model patent with announcement number CN217518374U discloses a clamping mechanism for a tire wear tester. During the process of lifting and lowering the tire, the pneumatic cylinder operates to cause the pneumatic rod to drive the L-shaped fixing frame to move in the vertical direction, thereby realizing the lifting and lowering function of the tire to be tested and ensuring that the circumferential surface of the tire can contact the circumferential surface of the grinding wheel.

[0004] In view of the above-mentioned technical solutions and the prior art, when a conventional rubber tire testing clamping device is used to clamp a rubber tire, due to the different sizes of rubber tires, direct clamping may result in an unstable clamping effect. At the same time, after the clamping is completed, in order to improve the detection effect, it is necessary to additionally start other driving devices to drive the rubber tire to rotate for detection, which is rather cumbersome. Therefore, we propose a rubber tire testing clamping device that can adapt to rubber tires of different sizes. Utility Model Content

The transmission assembly includes a main shaft, a secondary shaft, a limit shaft and an extrusion shaft, one end of the main shaft is fixedly connected to the grinding wheel, the surfaces of the main shaft and the secondary shaft are both sleeved with meshing gears, and the secondary shaft, the limit shaft, the extrusion shaft and the transmission screw are all connected through a transmission belt.

[0007] As a further improvement of the above solution, one end of the transmission screw is rotatably connected to the workbench, and a groove for the transmission screw to move is provided on the surface of the workbench.
