When the cut on the aircraft tire is at different positions, it is necessary to adjust the placement of the aircraft tire according to the position of the cut during the repair process, which is quite laborious. In this case, a cut repair device for aircraft tire processing realizes the function of flipping the backing plate 21 to adjust the position of the tire body 20 through the structural design of the backing plate 21. First, the tire body 20 is placed on the backing plate 21, and the rear end of the backing plate 21 is clamped by two sets of rotating rods 22 and fixed rods 37 to facilitate the rotation of the tire body 20. When the backing plate 21 is in a horizontal state, the tire body 2 0 to repair the incisions on the front and rear sides of the tire body 20, and after the threaded connection between the fixing bolts 30 and the rotating shaft 28 is released by rotating the fixing bolts 30, the pad 21 can be rotated and turned over to make it in a vertical state. In this process, the bottom end of the rotating plate 34 will contact the supporting plate 32 and finally be supported and fixed by the supporting plate 32, and the protrusions 35 on the rotating plate 34 can support the bottom end of the tire body 20. At this time, it is convenient to repair the incisions on the side and inner wall of the tire body 20, and finally the fixing bolts 30 are screwed on to fix the position of the rotating shaft 28 to prevent it from rotating again, wherein the bottom end of the rotating plate 34 is supported by the supporting block 36 to prevent the rotating plate 34 from rotating downward.
