[0035] The clamping assembly 5 is provided on the workbench 1 and is used to clamp the metal tabletop to be punched. The clamping assembly 5 includes a fixed plate 51, a threaded rod 52, a limit plate 53, and a handwheel 54. The fixed plate 51 is fixed to the top of the workbench 1, and the threaded rod 52 passes through the fixed plate 51 and is threadedly connected to the fixed plate 51. The limit plate 53 is fixed to the end of the threaded rod 52 near the drill bit 33, and the bottom of the limit plate 53 is in contact with the top of the workbench 1. The handwheel 54 is fixed to the other end of the threaded rod 52. There are two fixed plates 51, threaded rod 52, limit plates 53, and handwheel 54, and they are symmetrically arranged with respect to the workbench 1.

[0036] To facilitate the synchronous movement of the dust collection hose 43 with the expansion and contraction of the cylinder 21, a support assembly 6 for supporting the dust collection hose 43 is provided on the vertical plate of the mounting frame 2 on the side near the fan 41. The support assembly 6 includes a swivel seat 61 and a support tube 62. The swivel seat 61 is rotatably connected to the inner wall of the mounting hole 22.

The support tube 62 is provided with an expansion tube 621 at each end. The ends of the expansion tubes 621 facing away from each other are rounded. The provision of the swivel seat 61 facilitates the synchronous movement of the dust collection hose 43 with the expansion and contraction of the cylinder 21. The provision of the support tube 62 helps to improve the stability of the dust collection hose 43 during movement. The provision of the expansion tube 621 helps to reduce the probability of the dust collection hose 43 being compressed and bent, thereby improving the dust collection assembly 4's efficiency in collecting metal dust.

[0037] In order to help reduce the probability of the transparent dust cover 44 pressing against the surface of the workbench 1 during the descent of the drill bit 33 and the influence of the transparent dust cover 44 on the drill bit 33, a connecting ring 441 with a certain deformation ability is provided at the bottom of the transparent dust cover 44, which is conducive to the lower end of the drill bit 33 passing through the through hole 11 and completing the drilling of different depths on the metal table top.

[0038] In order to facilitate the staff to clean the metal dust collected inside the transparent storage box 42, a door is hinged on one side of the transparent storage box 42; in order to reduce the probability of metal dust entering the inside of the fan 41, a filter screen for protecting the fan 41 is provided on the inner bottom wall of the transparent storage box 42 (not shown in the figure, the filter screen is existing technology and will not be described in detail here).

[0039] The working principle of a punching device for metal table production in this embodiment is as follows: the worker first places the metal table board on the workbench 1, and then clamps the metal table board through the clamping assembly 5, which is beneficial to improving the stability of the metal table board during the punching process, thereby ensuring the accuracy of the punching position, and then starts the cylinder 21. After the cylinder 21 works, the worker starts the motor 31. After the motor 31 works, it drives the connecting rod 32 and the drill bit 33 to rotate, and cooperates with the movement of the cylinder 21, which is beneficial for the punching assembly 3 to punch metal table boards of different thicknesses, and at the same time, it is beneficial for the drill bit 33 to complete the punching work of different depths on the metal table board. The setting of the circular hole reduces the damage of the drill bit 33 to the workbench 1. The worker starts the fan 41. After the fan 41 works, negative pressure is generated. Through the vacuum hose 43 and the transparent vacuum hood 44, the light metal dust generated during the punching process of the metal table board is sucked into the transparent storage box 42, which is beneficial to reduce the probability of metal dust flowing with the air and scattering everywhere, thereby improving the cleanliness of the workbench 1.
