A slide column 22 is slidably connected inside the hole groove 21, and a plurality of clamps 23 are equidistantly installed on the outside of the slide column 22, and a clamping block 24 is installed above the clamping plate 23. This solves the problem that when drilling a flywheel disc, the traditional clamp only clamps the edge of the flywheel disc. Since the drill bit rotates at high speed during drilling, it will inevitably vibrate slightly when it comes into contact with the flywheel disc, causing the flywheel disc to slightly move up and down. After the drilling is completed, it is easy to have problems such as insufficient hole accuracy and unevenness inside the hole.

[0032] In this embodiment, the locking unit 3 includes:

[0033] The rotating assembly 31 is installed on the surface of the sliding column 22 to push the clamping plate 23 to slide. The rotating assembly 31 includes a plurality of connecting blocks 311. The connecting blocks 311 are located on the opposite sides of the clamping plate 23 and the sliding column 22. The surfaces of the connecting blocks 311 and the sliding column 22 are provided with a plurality of grooves 312. The two ends of the connecting blocks 311 are respectively rotated in the corresponding grooves 312 through connecting pins.

[0039] In this embodiment, the limiting assembly 34 includes a clamping block 341 that slides inside the through groove 332. The surface of the clamping block 341 is rotatably connected to a threaded rod 342. The threaded rod 342 penetrates the surface of the clamping block 24 and extends, and the threaded rod 342 is threadedly connected to the clamping block 24.

[0040] The top of the piston rod 6 is fixedly connected to the bottom end of the sliding column 22 by opening a through groove 332 on the surface of the clamping block 24, and the clamping plate 331 slides inside the through groove 332. The surface of the clamping block 341 is rotatably connected to the threaded rod 342, and the threaded rod 342 penetrates the surface of the clamping block 24 and extends. When the flywheel disc is fixed, the thickness of the flywheel disc will be different due to the model, purpose and other reasons. The fixing structure can be fixed above the flywheel disc according to the thickness of the flywheel disc, so as to prevent the flywheel disc from being slightly displaced during drilling, thereby improving the accuracy and stability of drilling.

[0041] During operation, the flywheel disc is placed on the surface of the operating table 1, the hole in the center of the flywheel disc is aligned with the hole groove 21, and then the cylinder 5 is started. The cylinder 5 pushes the sliding column 22 to slide upward through the internal sliding piston rod 6. The sliding column 22 slides and drives the connecting block 311 to rotate through the connecting pin. The connecting block 311 rotates to make the clamping plate 23 slide on the surface of the sliding rod 322. The clamping plate 23 slides to complete the expansion so that the clamping plate 23 fixes the flywheel disc from the inside. Then the clamping block 24 slides downward, and the clamping block 24 slides on the surface of the clamping plate 331 until it fits with the clamping disc. Then the threaded rod 342 is rotated, and the threaded rod 342 pushes the clamping block 341 to squeeze and fix the clamping plate 331 to complete the clamping of the flywheel disc. When disassembling, the top of the flywheel disc is disassembled by rotating the threaded rod 342, and then the cylinder 5 drives the piston rod 6 to slide downward.
