The liquid outlet end of the liquid delivery pump 10 is fixedly connected to a first hose 11, and the end of the first hose 11 away from the liquid delivery pump 10 passes through the lower shell 6 and extends to the inside of the lower shell 6. A water suction pump 12 is fixedly connected to the right side of the liquid storage tank 8, and the liquid outlet end of the water suction pump 12 passes through the liquid storage tank 8 and extends to the top of the filter cotton plate 9. The water outlet end of the water suction pump 12 is fixedly connected to a second hose 13, and the end of the second hose 13 away from the water suction pump 12 passes through the lower shell 6 and extends to the inside of the lower shell 6.

[0024] By utilizing the rotation of the bearing 4, the softness of the rubber tube 5 and the elastic force of the compression spring 7, the lower shell 6 can be allowed to contact the aluminum alloy door and window profile to cover the drilling position of the drill bit 2 and the aluminum alloy door and window profile without affecting the normal rotation of the drill bit 2. At this time, the liquid delivery pump 10 draws out the coolant in the liquid storage tank 8 and sends it into the lower shell 6 through the first hose 11 to directly contact the drill bit 2 being drilled, thereby quickly cooling the drill bit 2 to reduce thermal wear. The water suction pump 12 cooperates with the second hose 13 to suck the coolant that has completed the heat exchange in the lower shell 6 together with the debris into the liquid storage tank 8, and puts it back into use after filtering the aluminum chips through the filter cotton plate 9.

[0025] Furthermore, the bottom surface of the workbench 1 is fixedly connected to two supporting legs 14, and the bottom surface of each supporting leg 14 is fixedly connected to two mounting plates 15.

The upper surface of each stabilizing plate 20 is fixedly connected to the bottom surface of the fixed plate 18. The power provided by the hydraulic rod 17 cooperates with the support frame 16 to drive the fixed plate 18 to move downward, and then drive the rotating motor 19 and the drill bit 2 to move downward. At this time, the rotating motor 19 is used to drive the drill bit 2 to rotate, so as to perform drilling processing on the aluminum alloy door and window profiles, thereby ensuring the smooth drilling work of the aluminum alloy door and window production drilling machine. The stabilizing plate 20 can fix the position of the upper shell 3.

[0027] Furthermore, the front and back sides of the support frame 16 are fixedly connected with two reinforcing ribs 21, and the bottom surface of each reinforcing rib 21 is fixedly connected to the upper surface of the workbench 1. The reinforcing ribs 21 can increase the connection firmness between the support frame 16 and the workbench 1, making the support frame 16 less likely to loosen, thereby improving the matching reliability of the support frame 16 and the workbench 1.

[0032] Working principle: When in use, first use the support legs 14 to cooperate with the mounting plate 15 to set the workbench 1 at the required position for the work. When it is necessary to punch holes in the aluminum alloy door and window profiles, the power provided by the hydraulic rod 17 and the support frame 16 can drive the fixed plate 18 to move downward with the assistance of the sliding block 23 and the sliding groove 22, thereby driving the rotating motor 19 and the drill bit 2 to move downward. At this time, the rotating motor 19 is used to drive the drill bit 2 to rotate, so that the aluminum alloy door and window profiles can be punched. At this time, the upper shell 3 is used to cooperate with the bearing 4 and the rubber tube 5. When the drill bit 2 moves downward to punch holes in the aluminum alloy door and window profiles, the rotation of the bearing 4 and the softness of the rubber tube 5 and the elastic force of the compression spring 7 can be used to allow the lower shell 6 to contact the aluminum alloy door and window profiles without affecting the normal rotation of the drill bit 2, covering the drill bit 2 and the aluminum alloy door and window profiles. At the drilling position of the material, the suction provided by the liquid feeding pump 10 can be used to draw the coolant in the liquid storage tank 8 outward, and sent into the lower shell 6 through the first hose 11 to directly contact the drill bit 2 being punched, thereby quickly cooling the drill bit 2, so that the drilling machine for the production of aluminum alloy doors and windows has a good drill bit 2 cooling function when in use, effectively reducing the thermal wear of the drill bit 2 and increasing the service life of the drill bit 2. At the same time, the suction provided by the water suction pump 12 is used in conjunction with the second hose 13 to suck the coolant that has completed the heat exchange inside the lower shell 6 together with the debris into the liquid storage tank 8, and the aluminum chips are filtered through the filter cotton plate 9 in the liquid storage tank 8 and then put into use again, so that the coolant in the lower shell 6 always maintains a relatively low temperature and can be recycled, thereby ensuring the cooling efficiency of the drill bit 2 while further reducing the thermal wear of the drill bit 2 and reducing the waste of coolant.
