[0028] Such as Figures 1 to 11As shown, the utility model is an aircraft tire sidewall damage repair machine. When it is working, the tire is first placed on the arc segment surface of the bracket 12, and then the hydraulic cylinder 23 pushes the bracket 7 35 to enter the inside of the tire, and then the hydraulic cylinder 36 pushes the hot pressing head 1 38 to make the hot pressing head 1 38 close to the inner surface of the tire, and then the rotating joint 1 21 is opened to rotate the bracket 2 22 to be close to the side of the bracket 12, so that the remaining parts are inserted into the tire, and then the rotating joint 23 is opened to rotate the bracket 3 24 to make the roller 29 parallel to the sidewall, and then the hydraulic cylinder 1 25 is opened to pull the bracket 4 26 to make the roller 29 close to the sidewall, and then the motor 28 is turned on to rotate the roller 29, and the rotation of the roller 29 drives the tire to rotate to the processing position. When the clamping operation is performed, multiple groups The tire holding claws 02 always start the hydraulic cylinder 25 synchronously, and after the hydraulic cylinder 25 stops moving, the multiple sets of tire holding claws 02 on one side are always tightened first and then the multiple sets of tire holding claws 02 on the other side. Then the tire is trimmed. During trimming, the linear motor 2 51 pushes the linear motor 3 56 close to the processing position, and the linear motor 3 56 pushes the rough grinding head 71 close to the processing position. Then the telescopic electric spindle 60 drives the rough grinding head 71 to rotate and feed. The linear motor 2 51 and the linear motor 3 56 cooperate to move the rough grinding head 71 to rough grind the damaged area of the tire to remove the surface pattern and the damaged layer.

The linear motor 2 51 and the linear motor 3 56 cooperate to move the cleaning head 73 to clean the damaged area of the tire to remove processing debris and improve the bonding force of the tire to the raw rubber. Then, the telescopic electric spindle 60 drives the cleaning head 73 to retract, and then the tire is injected with glue.

During vulcanization, the hydraulic cylinder 3 36 is opened to push the hot pressing head 1 38 to squeeze the tire, and the linear motor 1 41 pushes the bracket 9 45 close to the tire, and then the hydraulic cylinder 4 46 is opened to push the hot pressing head 2 48 to fit with the outer surface of the tire.

After the damage on one side of the tire is repaired, loosen the hydraulic cylinder 1 25, and then turn on the rotating joint 2 23 and the rotating joint 1 21 in sequence. When performing the loosening operation, multiple groups of tire clamping claws 02 always synchronously start the hydraulic cylinder 1 25, and after the action of the hydraulic cylinder 1 25 stops, multiple groups of tire clamping claws 02 on one side are always opened first, and then multiple groups of tire clamping claws 02 on the other side are opened, so that the tire clamping claws 02 return to the open state, and then the tire can be removed.
