[0028] Working principle: When a self-repairing tire suffers a minor cut, a grinding device can be used to grind the cut to close it, achieving the effect of rapid repair. When the fixing device in the above tire processing and grinding device is in use, there is a phenomenon that tires of different sizes are not fixed firmly, which will reduce the accuracy of the grinding operation. For grinding tires at different angles, it takes a long time to adjust the tire angle, affecting the efficiency of the grinding operation.

The small motor 410 operates, and the bidirectional screw 405 rotates. The moving block 407 drives the sleeve 409 to move to both sides, so that the sleeve 409 and the rotating roller 412 simultaneously support the inner ring of the tire, achieving the preliminary fixation of the inner ring of the tire. Immediately afterwards, the motor 413 operates, the rotating shaft 411 drives the rotating roller 412 to rotate. With the cooperation of the sleeve 409, the tire rotates to an appropriate angle. The air cylinder 416 operates again, and the clamping plate 417 and the support frame 3 plate stably clamp the tire.
