Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technical personnel in this field without creative work are within the scope of protection of the utility model.

Since the plurality of second driven gears 6 are respectively meshed with the plurality of racks 9, when the plurality of second driven gears 6 rotate, the rack 9 can drive the plurality of clamping plates 10 to slide toward the middle of the top of the machine table 1 at the same time under the limiting action of the limiting groove 7 and the limiting block 8 to clamp and fix the motor housing, thereby realizing the fixation of the circular motor housing, solving the problem. In actual use, the punching device of the prior art can only fix a square motor casing. When fixing a circular motor casing, its fixing effect is poor and the stability is poor. A frame 11 is arranged on the top of the machine platform 1, and an electric push rod 12 is fixedly inserted in the middle of the frame 11. A second motor 13 is arranged at the output end of the electric push rod 12, and a drill bit 14 is fixedly connected to the output end of the second motor 13. The second motor 13 and the drill bit 14 are pushed downward by the electric push rod 12 to achieve the punching operation of the motor casing. A cleaning component is arranged at the bottom end of the second motor 13, and the cleaning component is sleeved on the outside of the drill bit 14. Through the setting of the cleaning component, the lifting plate 17 can drive the bristles 18 to slide downward quickly after the drill bit 14 is separated from the motor casing after drilling, so that the bristles 18 clean the outer wall of the drill bit 14 to avoid a large amount of debris remaining on the outer wall of the drill bit 14.

[0027] In this embodiment, the limit assembly includes a limit slot 7 and a limit block 8. The limit slot 7 is opened at the top of the inner cavity of the machine 1. The limit block 8 can be slidably embedded in the inner cavity of the limit slot 7 and is fixedly connected to the bottom end of the rack 9. When the rack 9 slides, the limit block 8 can slide synchronously in the inner cavity of the limit slot 7. Under the joint action of the limit block 8 and the limit slot 7, the rack 9 can always slide along a straight line, thereby improving the stability of the device during use.

[0028] In this embodiment, the inner cavity of the limit groove 7 is matched with the outer wall of the limit block 8 and both are in a "T" shape, so that one end of the limit block 8 can always remain embedded in the inner cavity of the limit groove 7, thereby improving the stability of the limit assembly during use, preventing the limit block 8 from escaping from the inner cavity of the limit groove 7 and causing the rack 9 to disengage from the second driven gear 6, thereby improving the stability of the device during use.

[0029] In this embodiment, the driving assembly includes a first motor 2, a driving gear 3, a rotating column 4, and a first driven gear 5.

Since the multiple second driven gears 6 are respectively meshed with the multiple racks 9, when the multiple second driven gears 6 rotate, the racks 9 can drive the multiple clamping plates 10 to slide toward the middle of the top of the machine table 1 at the same time under the limiting action of the limiting grooves 7 and the limiting blocks 8 to clamp and fix the motor housing, thereby realizing the fixation of the circular motor housing, solving the problem that the punching device of the prior art can only fix the square motor housing during actual use, and its fixing effect and stability are poor when fixing the circular motor housing.

[0033] In this embodiment, the telescopic assembly includes a telescopic cylinder 15, a telescopic rod 16 and a connecting assembly. The telescopic cylinder 15 is arranged at the top end of the lifting plate 17. The telescopic rod 16 can be slidably inserted in the inner cavity of the telescopic cylinder 15 and is fixedly connected to the output end of the second motor 13. The connecting assembly is arranged in the inner cavity of the telescopic cylinder 15 and is fixedly connected to the outer wall of the telescopic rod 16. When the lifting plate 17 slides up and down, the telescopic rod 16 slides synchronously in the inner cavity of the telescopic cylinder 15. The outer wall of the telescopic rod 16 is in close contact with the inner wall of the telescopic cylinder 15, so that the lifting plate 17 can always slide up and down along a straight line.

[0034] In this embodiment, the connecting assembly includes a connecting groove 20 and a connecting block 21. The connecting groove 20 is opened on one side of the inner wall of the telescopic tube 15. The connecting block 21 can be slidably embedded in the inner cavity of the connecting groove 20 and fixedly connected to the outer wall of the telescopic rod 16. Under the joint action of the connecting block 21 and the connecting groove 20, one end of the telescopic rod 16 can always be kept inserted in the inner cavity of the telescopic tube 15 to prevent the telescopic rod 16 from escaping from the inner cavity of the telescopic tube 15.
