The surface of the platform 18 is used to remove the first fixing pin 110 from the first fixing hole 19, then pull the grinding block 15 to contact the inner wall of the tire, and then insert the first fixing pin 110 into the first fixing hole 19, and then start the electric push rods 16 on both sides to drive the fixing plate 17 to move toward the outer wall of the tire. When the fixing plate 17 contacts the tire, the tire can be clamped and fixed, and then start the motor 11 to drive the rotating shaft 12 to rotate, which can simultaneously drive the connecting block 13 and the grinding block 15 to rotate. At this time, the grinding block 15 can grind the inner cavity of the tire. In this step, the first telescopic rod 14 is set to connect the connecting block 13 and the grinding block 15. Under the cooperation of the first fixing pin 110 and the first fixing hole 19, the electric push rod 16 drives the fixing plate 17 to clamp and fix the tire, which can adapt to grinding tires of different sizes, so as to reduce the need to frequently replace the corresponding fixing structure when grinding tires of different sizes.

[0025] like Figure 2 As shown, a plurality of sliding holes 2 are provided in the middle of the fixing plate 17; a plurality of spring rods 21 are slidably connected to the middle of the fixing plate 17; the sliding holes 2 and the spring rods 21 are aligned; during operation, when the electric push rod 16 drives the fixing plate 17 to contact the outer wall of the tire, the end of the spring rod 21 will first contact the tire, and when the fixing plate 17 clamps and fixes the tire, the end of the spring rod 21 will extend into the pattern gap on the surface of the tire, and at the same time, the spring rod 21 will respectively contract and generate rebound force to clamp and fix the tire. In this step, by setting the fixing plate 17 to connect the plurality of spring rods 21, the spring rod 21 can extend into the gap between the tire pattern when the tire is clamped and fixed, and the contact surface with the tire can be increased to improve the stability of the tire position during grinding.

[0026] like Figure 3As shown, the side wall of the connecting block 13 is fixedly connected to the second telescopic rod 3; a plurality of second fixing holes 31 are opened in the middle of the second telescopic rod 3; a second fixing pin 32 is provided in the middle of the second telescopic rod 3; the second fixing pin 32 is slidably matched with the second fixing hole 31; a connecting plate 33 is fixedly connected to the end of the second telescopic rod 3; a plurality of bristles 34 are fixedly connected to the side wall of the connecting plate 33; when working, after the position of the tire is fixed, the second fixing pin 32 is taken out of the second fixing hole 31 and then the connecting plate 33 is moved toward the inner wall of the tire. When the bristles 34 are in contact with the inner wall of the tire, the second fixing pin 32 is removed from the second fixing hole 31 and then the connecting plate 33 is moved toward the inner wall of the tire. After the wall is contacted, the second fixing pin 32 is inserted into the second fixing hole 31. When the motor 11 drives the connecting block 13 to rotate, the bristles 34 will be driven to rotate at the same time, so that the bristles 34 can clean the inner wall of the tire during grinding. In this step, the second telescopic rod 3 is set to connect the connecting block 13 and the bristles 34, so that the inner wall of the tire can be cleaned during grinding, so as to reduce the situation where debris generated during grinding remains in the inner cavity and causes uneven grinding. The cooperation between the second telescopic rod 3 and the second fixing hole 31 and the second fixing pin 32 can adapt to tires of different sizes to improve the applicability of the structure.

[0027] like Figure 4 As shown, a plurality of collecting holes 4 are provided in the middle of the grinding table 18; a collecting box 41 is fixedly connected to the bottom of the grinding table 18; during operation, part of the debris generated when the tire is ground on the surface of the grinding table 18 will fall from the collecting holes 4 into the collecting box 41 below, and the collecting box 41 can collect the debris at this time. In this step, by setting the collecting holes 4 and the collecting box 41, part of the debris generated during grinding can fall from the surface of the grinding table 18 and be collected, so as to reduce the situation where the debris remains on the surface of the grinding table 18, resulting in an uneven position when the tire is placed, thereby affecting the grinding effect.

[0028] like Figure 4 As shown, a pull-out box 5 is placed inside the collection box 41; the pull-out box 5 is slidably matched with the collection box 41; during operation, when debris enters the collection box 41 from the collection hole 4, the pull-out box 5 is located in the collection box 41, and the debris can enter the pull-out box 5 to be collected. When the collection is completed, the pull-out box 5 can be drawn out of the collection box 41 to pour out the debris therein, and then the pull-out box 5 can be put back into the collection box 41. In this step, the debris can be collected by arranging the pull-out box 5 to be located in the collection box 41, and the extractable and retractable structure of the pull-out box 5 can facilitate the removal of the collected debris to improve the convenience of debris collection.

[0029] like Figure 1As shown, a water pump 6 is fixedly connected to the top of the grinder body 1; a water outlet pipe 61 is connected to the side wall of the water pump 6; when working, an external water source is connected to the water pump 6 and then the water pump 6 is started to send water to the water outlet pipe 61, and the end of the water outlet pipe 61 is inclined toward the inner wall of the tire so that water can be sprayed into the inner cavity of the tire, and the tire can be cleaned and cooled down. In this step, by setting the water pump 6 and the water outlet pipe 61, water can be sprayed into the inner cavity of the tire during grinding, and the tire can be cleaned and cooled down, which can reduce the deformation of the tire caused by high temperature during grinding and improve the cleanliness of the inside of the tire.

[0030] like Figure 2 As shown, the end of the spring rod 21 is fixedly connected to a suction cup 7; during operation, when the end of the spring rod 21 contacts the tire surface, the suction cup 7 will be adsorbed on the tire surface. This step increases the contact area between the spring rod 21 and the tire by arranging the suction cup 7 to be adsorbed on the tire surface, thereby reducing the movement of the tire position when the spring rod 21 is clamped and fixed on the tire.

[0031] Working principle: When grinding the inner cavity of the tire, place the tire on the surface of the grinding table 18, take out the first fixing pin 110 from the first fixing hole 19, pull the grinding block 15 to contact the inner wall of the tire, insert the first fixing pin 110 into the first fixing hole 19, and then start the electric push rods 16 on both sides to drive the fixing plate 17 to move toward the outer wall of the tire. When the fixing plate 17 contacts the tire, the tire can be clamped and fixed, and then start the motor 11 to drive the rotating shaft 12 to rotate, which can simultaneously drive the connecting block 13 and The grinding block 15 rotates and the grinding block 15 can grind the inner cavity of the tire. When the electric push rod 16 drives the fixing plate 17 to contact the outer wall of the tire, the end of the spring rod 21 will first contact the tire. When the fixing plate 17 clamps and fixes the tire, the end of the spring rod 21 will extend into the pattern gap on the tire surface. At the same time, the spring rod 21 will contract and generate rebound force to clamp and fix the tire. After the position of the tire is fixed, the second fixing pin 32 is taken out from the second fixing hole 31 and then the connecting plate 33 is moved toward the tire. When the brush 34 contacts the inner wall of the tire, the second fixing pin 32 is inserted into the second fixing hole 31. When the motor 11 drives the connecting block 13 to rotate, the brush 34 is driven to rotate at the same time, so that the brush 34 can clean the inner wall of the tire during grinding. Part of the debris generated when the tire is ground on the surface of the grinding table 18 will fall from the collecting hole 4 to the collecting box 41 below. At this time, the collecting box 41 can collect the debris. When the debris enters the collecting box 41 from the collecting hole 4, the pull-out box 5 is located in the collecting box 4. 1, at this time, the debris can enter the pull-out box 5 to collect the debris. After the collection is completed, the pull-out box 5 can be pulled out from the collection box 41 to pour out the debris therein and then put the pull-out box 5 back into the collection box 41. The external water source is connected to the water pump 6 and then the water pump 6 is started to send water to the water outlet pipe 61. The end of the water outlet pipe 61 is inclined toward the inner wall of the tire so that the water can be sprayed into the inner cavity of the tire, and the tire can be cleaned and cooled. When the end of the spring rod 21 contacts the tire surface, the suction cup 7 will be adsorbed on the tire surface.
