Four isolation plates 6 are vertically fixed at the bottom of the top plate 1 through bolts, only the rear two isolation plates are shown in fig. 1, the four isolation plates 6 are positioned at the periphery of the clamping block 9, and a through hole (not shown in the figure) for the isolation plates 6 to pass through is formed in the workbench 10. The bottom ends of the four isolation plates 6 are all in a wedge shape matched with the top of the clamping block 9, and the isolation plates 6 can drive the clamping block 9 to slide to clamp the workpiece 8. The four isolation plates 6 are all hollow, the inner sides of the four isolation plates 6 are all provided with the suction holes 7, the tops of the outer sides of the four isolation plates 6 are all provided with the chip removal ports 17, and the chip removal ports 17 are rotatably provided with the negative pressure fan 13.

The bottom of the top plate 1 is provided with a plurality of drill bits 5, and a workbench 10 is provided with a drill hole (not shown in the figure) for the drill bits 5 to pass through. In this embodiment, the number of the drill bits 5 is nine (only some of the drill bits 5 are shown in the figure, and the number of the drill bits 5 can be set according to the actual drilling requirement), and the nine drill bits 5 are uniformly distributed on a circle. The top plate 1 is provided with a driving mechanism for driving the drill bits 5 to synchronously rotate, the driving mechanism comprises a driving wheel 15, a plurality of driven wheels 14 (only two driven wheels are shown in fig. 2) are meshed at the periphery of the driving wheel 15, the number of the driven wheels 14 is the same as that of the drill bits 5, and the drill bits 5 are connected with the driven wheels 14 in a one-to-one correspondence manner. The driving shafts of the four driven wheels 14 corresponding to the positions of the negative pressure fans 13 are connected with transmission belts 16, and the four transmission belts 16 are respectively tensioned on the four negative pressure fans 13.

The drilling machine further comprises a cooling mechanism, wherein the cooling mechanism comprises a cooling liquid tank, water pumps (not shown in the figure) and water pipes 18, the cooling liquid tank is fixed on the bottom plate 12 and is communicated with the water pumps, the water pumps are communicated with the water pipes 18, the number of the water pipes 18 is the same as that of the drill bits 5, only a part of the water pipes 18 are shown in the figure, and the water pipes 18 are fixed at the drill holes in a one-to-one correspondence mode.

After clamping, the workbench 10 moves upwards continuously, and the drill 5 drills the workpiece 8 (at this time, the isolation plate 6 abuts against the outer side of the clamping block 9, and the clamping block 9 does not influence the workbench 10 to move upwards continuously). When the driven wheel 14 rotates, the negative pressure fan 13 is driven to rotate through the transmission belt 16, negative pressure is generated at the negative pressure fan 13, and scraps generated during drilling are pumped into the isolation plate 6 from the suction hole 7 and finally discharged from the scrap discharge port 17. Because the partition plate 6 surrounds the drill 5 and the workpiece 8 during drilling, the scraps cannot float out, and the scraps can be sucked into the partition plate 6 to the maximum extent.

During drilling, the water pump is started, the water pump pumps the cooling liquid to the water pipe 18, the water pipe 18 sprays water to the drill bit 5, the drill bit 5 is cooled, damage caused by the fact that the temperature of the drill bit 5 is too high is avoided, and meanwhile, residual scraps on the drill bit 5 can be washed. Sprayed cooling liquid can be collected in the water collecting cover 19 and is finally discharged from the sewage discharge pipe, so that the cooling liquid is prevented from being sprayed to the equipment and the surface of the workbench 10, and the processing environment is protected.
