The output end of the third motor 7010 is fixedly connected to a drill bit 7011 through a standardized chuck.

[0025] Furthermore, the transverse guide rail 701 is used to provide support for lateral movement. By driving the first lead screw 702 with the first motor 703, the lateral movement of the first sliding seat 704 can be controlled. The longitudinal guide rail 705 is used to provide support for longitudinal movement. By driving the second lead screw 706 with the second motor 7061, the longitudinal movement of the second sliding seat 707 can be controlled. The third motor 7010 is used to drive the operation of the drill bit 7011 to perform the punching operation.

Drive the second bidirectional threaded rod 13 and the fifth motor 19 to rotate through the fourth motor 18 and the fifth motor 19, adjust the distance between the four adjusting seats 15, so that the inner sides of the four adjusting seats 15 are in contact with the four corners of the bottom end of the sheet metal housing. Then, set the punching position through the numerical control device, and drive the first lead screw 702 through the first motor 703 to control the lateral movement of the first sliding seat 704. Drive the second lead screw 706 through the second motor 7061 to control the longitudinal movement of the second sliding seat 707, and move the drill bit 7011 to the pre-punching position. Then, drive the operation of the drill bit 7011 through the third motor 7010, and drive the drill bit 7011 to approach the surface of the sheet metal housing to perform the punching operation by using the electric push rod 708. Among them, multiple punching assemblies 7 will perform punching operations on different surfaces of the sheet metal housing at the same time, improving the production efficiency. The waste generated during the punching process falls into the chip collection box 6 through the chip collection groove 4, keeping the workbench 1 clean and facilitating the subsequent treatment of the waste.
