When the drive shaft rotates, the driven gear is driven to rotate through the drive gear, and the impeller is driven to rotate by the driven gear through the drive shaft, driving the air flow to circulate, so that the air flow blows towards the clutch, dissipating heat from the clutch during drilling, and at the same time blowing off the drilled debris. Please refer to Figures 1-4, including: a drill press 100 and an air-cooling mechanism 200.

[0029] The drill press 100 includes a bed body 110, a spindle box 120, a drive shaft 130, a drill bit 140, and a three-jaw chuck 150. The spindle box 120 is arranged on the right side of the top of the bed body 110, the drive shaft 130 is arranged at the left end of the spindle box 120, the drill bit 140 is arranged at the end of the drive shaft 130, and the three-jaw chuck 150 is arranged on the left side of the top of the bed body 110;

[0030] Among them, the clutch is clamped and fixed by the three-jaw chuck 150, the drive shaft 130 works to drive the drill bit 140 to rotate, and the clutch is drilled.

[0031] The air-cooling mechanism 200 is arranged outside the spindle box 120.

[0032] Among them, when the drive shaft 130 rotates, it synchronously drives the driving gear 210 to rotate. The driving gear 210 meshes with and drives the driven gear 230 to rotate, and the driven gear 230 drives the impeller 240 to rotate through the transmission shaft 220.

[0033] To further improve the cooling effect, a water-cooling mechanism 300 is arranged on the left side of the bed body 110. The water-cooling mechanism 300 includes a water tank 310, a water suction pipe 320, a water trough 330, a drain pipe 340, a pump 350, and a gooseneck pipe 360. The bottom of the water tank 310 is connected to the water trough 330 through the water suction pipe 320, the top of the water tank 310 is connected to the gooseneck pipe 360 through the drain pipe 340, and the pump 350 is arranged on the drain pipe 340;

[0034] Among them, the pump 350 drives the water to flow, so that the water in the water tank 310 is discharged from the gooseneck pipe 360. The water outlet direction is adjusted through the gooseneck pipe 360, so that the water falls on the clutch for cooling, and the fallen water enters the water trough 330.

[0035] Since the water needs to be recycled, a long strip-shaped magnet 370 is arranged inside the water trough 330. The magnets 370 are evenly distributed in the water trough 330. The magnets 370 are used to adsorb the debris, collect the metal debris generated by drilling, and at the same time, prevent the debris from flowing into the water tank 310 along with the water flow.

[0036] To facilitate the control of the water flow, a control valve is arranged on the water suction pipe 320, and the control valve is used to control the flow of the water suction pipe 320.

[0037] For the convenience of observing the water flow margin, a transparent window is provided on the side wall of the water tank 310, and a liquid level identification scale is set on the transparent window. The remaining amount of water in the water tank 310 is observed through the liquid level identification scale and the transparent window.

[0038] For the convenience of taking out the water tank 330, a pipe joint is provided on the side of the water tank 330. The water suction pipe 320 is inserted and connected with the pipe joint. The insertion and embedding structure is adopted to facilitate the installation, disassembly and taking out of the water tank 330.

[0039] During specific use, the clutch is clamped and fixed by the three-jaw chuck 150, the drive shaft 130 works to drive the drill bit 140 to rotate, and the clutch is drilled. When the drive shaft 130 rotates, it synchronously drives the drive gear 210 to rotate. The drive gear 210 meshes with and drives the driven gear 230 to rotate. The driven gear 230 drives the impeller 240 to rotate through the transmission shaft 220, thereby driving the air flow to circulate, so that the air flow blows towards the clutch for heat dissipation. The pump 350 drives the water flow to circulate, so that the water in the water tank 310 is discharged from the gooseneck pipe 360. The water outlet direction is adjusted through the gooseneck pipe 360, so that the water falls on the clutch for cooling. The fallen water enters the water tank 330, and then is pumped into the water tank 310 through the water suction pipe 320 for recycling. The magnet 370 is used to adsorb the debris to collect the metal debris generated by drilling. At the same time, it can prevent the debris from entering the water tank 310 along with the water flow.

[0040] Although the present invention has been described above with reference to the embodiments, various improvements can be made to it and its components can be replaced with equivalents without departing from the scope of the present invention.
