[0038] The protection component 001 for plugging the balancing hole includes a protection plate 100. A first chute 110 for limiting the control box 200 is provided in the middle of the protection plate 100. When the control box 200 slides in the cavity of the first chute 110, it drives the adjusting block 300 to move away from or close to the two first rotating blocks 130, thereby adjusting the distance between the adjusting block 300 and the first rotating block 130 according to the size of the balancing hole.

[0039] A first limiting block 120 is fixedly installed at the upper end of the protection plate 100. There are two first limiting blocks 120, symmetrically arranged on both sides of the protection plate 100. A limiting groove 121 is provided at the lower end of the first limiting block 120, and the baffle 230 slides in the cavity of the limiting groove 121. A second chute 122 is provided at the upper end of the first limiting block 120, and a clamping groove 123 for locking the adjustment component 002 is provided at the upper end of the cavity of the second chute 122. Two first rotating blocks 130 are movably installed at the lower end of the protection plate 100. A first limiting post 131 for limiting the first rotating block 130 is installed in the middle of the first rotating block 130, and the first limiting post 131 is fixedly installed at the bottom of the protection plate 100. By the first rotating block 130 being movably sleeved on the first limiting post 131, the first rotating block 130 can rotate on the inner wall of the balancing hole, so as to facilitate shot peening of the balancing hole.

[0040] In the middle of the protection component 001, an adjustment component 002 is installed for facilitating adjustment according to the size of the balance hole. At the upper end of the adjustment block 300, a control box 200 is installed for limiting the adjustment block 300. On one side of the control box 200, a baffle 230 is fixedly installed for blocking the first chute 110. The control box 200 includes a box body 210, and the baffle 230 is installed on one side of the box body 210, so that when adjusting the distance between the adjustment block 300 and the first rotating block 130 according to the size of the balance hole, the baffle 230 blocks the first chute 110.

[0041] An elastic plate 211 is installed inside the box body 210. The elastic plate 211 is in the shape of a V-shaped block. The elastic plate 211 abuts against the bottoms of two arc-shaped plates 420, facilitating pushing the lower ends of the arc-shaped plates 420 to both sides, so that the clamping blocks 412 are engaged with the card slots 123. At the upper end of the box body 210, a handle 212 for limiting the arc-shaped plate 420 is fixedly installed. A convex block is installed at the upper end of the handle 212. A cavity is formed at the upper end of the arc-shaped plate 420, and the convex block is located in the cavity at the upper end of the arc-shaped plate 420, so that when the lower end of the arc-shaped plate 420 moves to both sides, the upper end of the arc-shaped plate 420 is limited by the convex block, and the arc-shaped plate 420 is inclined.

[0042] At the lower end of the box body 210, a second limiting post 220 for limiting the adjustment block 300 is fixedly installed. A gear 221 for controlling the rotation of the adjustment block 300 is installed in the middle of the second limiting post 220. A rotating rod 222 is fixedly installed at the upper end of the gear 221. At the upper end of the rotating rod 222, a motor 223 for cooperating with the rotating rod 222 to control the rotation of the gear 221 is installed, and the motor 223 is installed inside the box body 210.

[0043] During shot peening, by starting the motor 223, the rotating rod 222 is driven to rotate, so that the gear 221 cooperates with the tooth block 311 to drive the second rotating block 310 to rotate in the balance hole, so that the second rotating block 310 and the two first rotating blocks 130 rotate on one side of the balance hole, and the second rotating block 310 and the two first rotating blocks 130 always fit against the inner wall of the balance hole, so as to facilitate shot peening of the balance hole.

[0044] The adjustment component 002 includes an adjustment block 300 for cooperating with the two first rotating blocks 130 and the balance hole to limit the protection plate 100. The adjustment block 300 includes a second rotating block 310. The second rotating block 310 is sleeved on the second limiting post 220. A tooth block 311 for cooperating with the gear 221 to control the rotation of the second rotating block 310 is fixedly installed inside the second rotating block 310. Anti-slip pads 320 are fixedly installed on the outer walls of the upper and lower ends of the second rotating block 310 to prevent the second rotating block 310 from moving out of the balance hole.

[0045] A clamping assembly 400 for locking the control box 200 in cooperation with the card slot 123 is installed in the middle of the control box 200. The clamping assembly 400 includes two fixing blocks 410. The two fixing blocks 410 are on both sides of the handle 212. One end of the fixing block 410 is fixedly installed with a slider 411 for sliding in the cavity of the second chute 122, and one end of the fixing block 410 is fixedly installed with a clamping block 412 for engaging with the card slot 123. One end of the fixing block 410 is movably installed with an arc-shaped plate 420 for controlling the telescopic movement of the fixing block 410 inside the box body 210. One end of the arc-shaped plate 420 is fixedly installed with a second limiting block 421 for limiting the fixing block 410.

[0046] When adjusting the distance between the second rotating block 310 and the first rotating block 130 according to the size of the balance hole, by holding the arc-shaped plates 420 on both sides of the handle 212, driving the two arc-shaped plates 420 to squeeze the elastic plate 211, and at the same time driving the two fixing blocks 410 to move towards the inside of the box body 210, so that the clamping block 412 cancels the engagement with the card slot 123, then the control box 200 can move in the cavity of the first chute 110. When the second rotating block 310 cooperates with the two first rotating blocks 130 to abut against the inner wall of the balance hole, release the arc-shaped plate 420. When the elastic plate 211 resets, it pushes the lower ends of the two arc-shaped plates 420, so that the arc-shaped plates 420 drive the fixing blocks 410 to move towards the cavity direction of the second chute 122, so that the clamping block 412 and the card slot 123 are engaged, completing the position locking of the second rotating block 310, and making the second rotating block 310 rotate more stably in the balance hole.
