[0026] Specific implementation and principle:

[0027] In actual application of the present invention, the flywheel 8 to be drilled is placed in the mounting groove 31 of the fixed plate 3, and then the worker pulls the pull rod 492 of the limit assembly 49 outward with one hand, and the spring 494 on the pull rod 492 is compressed. The worker holds the vertical plate 44 with the other hand and presses the connecting plate 41 downward. The connecting plate 41 moves along the guide rod 461, and the spring 47 on the guide rod 461 is compressed. When the connecting plate 41 moves downward, the insertion rod 43 on the support block 431 passes through the arc-shaped driving groove on the pressure plate 42. 421 drives the pressure plate 42 to press against the flywheel 8. When the limit plate 48 contacts the support plate 481, the pressure plate 42 presses the flywheel 8 tightly. At this time, the pull rod 492 is released. Under the elastic force of the spring 494, the plug block 493 moves and inserts into the slot of the limit plate 48 to limit the limit plate 48. Then, the cylinder 65 and the drilling motor 63 are started. The piston rod of the cylinder 65 drives the drilling motor 63 to move down along the slide rail on the guide plate 61. The drill bit on the drilling motor 63 punches the flywheel 8. After the drilling of one hole is completed, the piston rod of the control cylinder 65 drives the drilling motor 63 to move up along the slide rail of the guide plate 61, and then the drive motor 51 is started. The pulley 1 52 on the output shaft of the drive motor 51 drives the pulley 2 54 and the rotating shaft 2 to rotate through the belt 53, and the fixed plate 3 and the flywheel 8 thereon rotate to the next position. Then the piston rod of the control cylinder 65 drives the drilling motor 63 to move down along the slide rail of the guide plate 61 to drill another position of the flywheel 8. After completion, the piston rod of the control cylinder 65 drives the drilling motor 63 to move up along the slide rail of the guide plate 61, and the drilling motor 63 is turned off. Then the pull rod 492 is pulled outward, and the plug block 493 on the pull rod 492 disengages from the limit plate 48. Under the elastic force of the spring 47 on the guide rod 461, the connecting plate 41 moves up, and the plug rod 43 on the support block 431 drives the pressure plate 42 to release the flywheel 8 through the arc-shaped driving groove 421 on the pressure plate 42, and then the processed flywheel 8 can be removed from the fixed disk 3.

[0028] To sum up, when limiting the flywheel 8, the present invention uses the pressure plates 42 on both sides of the connecting plate 41 to press and limit the flywheel 8, and uses the plug block 493 of the limiting assembly 49 to position the pressure plate 42. When releasing the flywheel 8, it is only necessary to pull the pull rod 492 to make the plug block 493 on the pull rod 492 separate from the limiting plate 48. Under the elastic force of the spring 47 on the guide rod 461, the connecting plate 41 moves up to make the pressure plates 42 on both sides release the flywheel 8. Then the flywheel 8 can be removed from the fixed disk 3. The whole process of pressing and releasing the flywheel 8 is very convenient.

[0029] The present invention is described above by way of example in conjunction with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the concept and technical solution of the present invention, or the practical invention and technical solution are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
