[0034] When the drilling machine 5 gradually approaches the drilling platform 1 , the positioning plate 61 is pressed against the PCB board, and then the drill bit 51 passes through the sleeve hole 62 to drill the PCB board.

[0035] The utility model provides a PCB drilling machine. When drilling, the PCB board is placed on a drilling platform, and a lifting mechanism drives a drill sleeve mechanism and a drilling machine to descend. The drill first passes through the sleeve hole, then contacts the PCB board, and finally completes the drilling.

PCB boards of different sizes can be supported, and the supporting force is uniform to avoid crushing the PCB board. At the same time, it can also prevent the drilling platform from being damaged.

[0037] Furthermore, as a preferred implementation mode of the present invention but not a limitation, the lifting mechanism 4 includes a lifting screw 41, a lifting motor 42 for driving the lifting screw 41 to rotate, lifting guide columns 43 arranged on both sides of the lifting screw 41, and a lifting seat 44 cooperating with the lifting screw 41, and the drilling machine 5 is arranged on the lifting seat 44.

[0039] Further, as a preferred implementation of the present solution but not limiting, a spring 63 is provided in the cavity 431 to press against the lifting guide column 43 and the sleeve column 60 respectively to prevent the PCB board from being crushed.

By using the bottom tube, the drill bit can be stabilized in the tube hole at the moment of drilling through, avoiding the drill bit from breaking.
