[0024] During operation, in the tire inner cavity grinding machine for tire production in the above technology, when the aircraft tire is driven to rotate by the electric roller, since there is no corresponding clamping structure, when the rotation speed is too fast, the aircraft tire cannot rotate stably. The structural design of the clamping mechanism realizes the function of clamping and fixing the tire body 20 during the rotation process. When the tire body 20 is to be clamped and fixed, the tire body 20 is first placed between the two sets of fixing rods 29, and the two sides of the tire body 20 will contact the fixing rods 29 and push The fixing rod 29 moves to both sides until it moves to the maximum position, and the bottom end of the fixing rod 29 is fixed on the supporting rod 28, and the bottom end of the supporting rod 28 is connected together through the connecting block 24 and the connecting rod 23. Since the connecting rod 23 is rotatably connected with the connecting block 24 and the rotating disk 22, the rotating disk 22 will rotate in the fixing box 38, wherein the connecting block 24 is fixed with a clamping block 25 on both sides, and the connecting block 25 slides in the clamping groove 26, so that the connecting block 24 can only move in the horizontal direction, thereby ensuring that the supporting rod 28 can move stably.

[0025] Furthermore, two sets of pulleys 36 are welded and fixed to the bottom end of the support rod 28, and the pulleys 36 are slidably connected to the slide grooves 37, and the slide grooves 37 are opened at the top of the fixed box 38;

[0026] During operation, the pulley 36 is fixed to the bottom end of the support rod 28 to assist in supporting the bottom end of the support rod 28 so that the support rod 28 can move more smoothly.

[0027] Furthermore, a screw 35 is threadedly connected to the middle of the fixing box 38, and the bottom end of the screw 35 abuts against the rubber pad 34, and the rubber pad 34 is glued and fixed to the top of the rotating disk 22;

[0029] Furthermore, a gasket 33 is glued and fixed on the inner wall of one side of the through groove 27, and the gasket 33 is made of rubber material;

[0030] During operation, the gasket 33 is made of rubber material and is used to provide a buffer between the connecting block 24 and the inner wall of the through slot 27 to prevent the connecting block 24 from directly abutting against the inner wall of the through slot 27 .

[0031] Furthermore, a plurality of first rollers 30 are rotatably connected inside the fixing rod 29, and the first rollers 30 are in contact with both sides of the tire body 20;

[0032] During operation, the first roller 30 contacts both sides of the tire body 20 so as to clamp and fix the tire body 20 while reducing the friction between the tire body 20 and the fixing rod 29 .

[0033] Furthermore, a long rod 31 is welded and fixed on one side of the fixing rod 29 close to the tire body 20, and a second roller 32 is rotatably connected to the long rod 31, and the second roller 32 is in contact with the tire body 20;

[0034] During operation, the second roller 32 contacts the tire body 20 and can fix the tire body 20 . At the same time, the second roller 32 rotates on the long rod 31 and can rotate along with the rotation of the tire body 20 .

[0035] Working principle: In the prior art, a tire inner cavity grinder for tire production has no corresponding clamping structure when the aircraft tire is rotated by an electric roller. When the rotation speed is too fast, the aircraft tire cannot rotate stably. In this case, the inner cavity grinder for aircraft tire production realizes the function of clamping and fixing the tire body 20 during the rotation process through the structural design of the clamping mechanism. When the tire body 20 is to be clamped and fixed, the tire body 20 is first placed between the two sets of fixing rods 29, and the two sides of the tire body 20 will be fixed with the fixing rods 29. The fixed rod 29 contacts and pushes the fixed rod 29 to move to both sides until it moves to the maximum position. The bottom end of the fixed rod 29 is fixed on the support rod 28. The bottom end of the support rod 28 is connected together through the connecting block 24 and the connecting rod 23. Since the connecting rod 23 is rotatably connected to the connecting block 24 and the rotating disk 22, the rotating disk 22 will rotate in the fixed box 38. The connecting block 24 is fixed with a card block 25 on both sides. The card block 25 slides in the card slot 26, so that the connecting block 24 can only move in the horizontal direction, thereby ensuring that the support rod 28 can move stably.
