The nut pushes the connecting seat and clamping pad to expand radially until the clamping pad is tightly attached to the inner wall of the tire to complete the fixation. This provides radial clamping force and avoids damage to the tire body, achieving automatic centering and fixing of the tire, preventing processing displacement, and protecting the internal structure. The movement trajectory of the clamping components is rigidly constrained to ensure the movement stability of the clamping mechanism. Furthermore, the clamping components are made of elastic rubber material, avoiding direct contact between hard clamping components and the inner wall of the tire, reducing damage to the internal structure of the tire body.

The output shaft of the first motor is started to drive the drive gear to rotate. The drive gear meshes with multiple driven gears, driving all rotating shafts to rotate synchronously. The removal flywheel at the end of the rotating shaft rotates at high speed to cut and remove the flash on the tire surface. Attached Figure Description
