Both ends of the roller shaft of the second pressure roller 4 are connected to the second bearing 41, which is connected to the second mounting block 1211.
[0023] By setting the first bearing 31 and the second bearing 41 as described above, the first pressure roller 3 is rotatably connected on the first mounting block 131, and the second pressure roller 4 is rotatably connected on the second mounting block 1211.
[0024] The drilling assembly 2 includes a lifting cylinder 21, a mounting frame 22, a pushing cylinder 23, a connecting frame 24, a punching motor 25, a connecting block 26, and a punch 27. The lifting cylinder 21 is connected to the first fixed frame 11 and is arranged vertically. The mounting frame 22 is connected to the end of the piston rod of the lifting cylinder 21 that passes through the first fixed frame 11. The mounting frame 22 is a rectangular frame.

[0025] The locking assembly 6 includes a lifting cylinder 61 and a locking block 62. The lifting cylinder 61 is connected to the lower part of the first mounting block 131 and is located in the middle of the two first pressure rollers 3. The locking block 62 is connected to the end of the piston rod of the lifting cylinder 61 that enters the first mounting groove.

[0026] A first limiting ring plate 32 is connected to the first pressure roller 3. The first limiting ring plate 32 is arranged along the circumference of the first pressure roller 3.

This allows for quick positioning of the flywheel and restricts its lateral movement, which helps to improve the stability of the flywheel clamping.

Then, the second mounting block 1211 is lowered by the hydraulic cylinder 121, and the flywheel is clamped by the first pressure roller 3 and the second pressure roller 4. The second pressure roller 4 is driven to rotate by the rotating motor 5. With the cooperation of the second pressure roller 4 and the first pressure roller 3, the flywheel rotates slowly, adjusting the hole position on the flywheel that needs to be punched to the vertical axis. Then, the lifting cylinder 61 pushes the locking block 62 to lock the second pressure roller 4, preventing the flywheel from rotating during subsequent punching operations. Afterwards, the position of the drill bit is adjusted by the lifting cylinder 21. With the cooperation of the pushing cylinder 23 and the punching motor 25, punching operations can be performed on the holes on the center or vertical axis of the flywheel. Due to the cooperation of the first pressure roller 3 and the second pressure roller 4, punching operations can also be performed on flywheels of different diameters, thereby improving the problem of its inconvenience in drilling different positions of the flywheel and improving the clamping effect and production efficiency of the drilling device.
