At the same time, the lifting rod 6 drives the pressing block 7 to descend, so that the pressing block 7 presses against the top surface of the workpiece 32 to prevent the workpiece 32 from jumping during drilling and improve the machining stability.

[0036] Then, the first translation driving member 9 drives the first electric drill bit 8 to move in the X-axis direction to achieve feeding, so that the first electric drill bit 8 passes through the avoidance hole 3 and drills holes in the side surface of the workpiece 32. The waste chips generated by drilling fall onto the inclined plate 4 and then slide along the inclined plate 4 into the chip collection groove 5 for collection. At the same time, the second cylinder 20 drives the third translation driving member 19, the mounting bracket 18 and the second electric drill bit 17 to move in the Z-axis direction to achieve the drilling feed of the second electric drill bit 17, so that the second electric drill bit 17 passes through and drills holes in the middle of the workpiece 32. The air is sucked through the air suction pipe 27 towards the air suction port 26, so that a negative pressure is formed in the cavity of the chip collection box 25 and the chip collection box 25. Then, the waste chips generated by the drilling of the second electric drill bit 17 are sucked into the cavity through the chip suction port 24, and then the waste chips enter the chip collection box 25 from the cavity for collection.
