[0024] The present invention has the following beneficial effects:

[0025] 1. In the present invention, the cooling water is first discharged by the water pump, and then the sealing assembly is opened to connect the chip discharge groove with the liquid storage tank. Then, the output end of the multi-stage electric push rod pushes the through pipe and the rotating nozzle to move to the right to fully flush the inner wall of the liquid storage tank, so that the impurities and oil attached to the inner wall of the liquid storage tank flow into the inside of the chip discharge groove. Finally, the reduction motor is started, and the output end of the reduction motor drives the spiral conveying rod to discharge the impurities and sewage, thereby achieving the effect of quickly and comprehensively cleaning the inner wall of the liquid storage tank.

[0026] 2. In the present invention, the oil suction pump extracts the oil floating on the surface of the cooling water through the oil suction pipe and the oil suction head, so that the oil is separated from the cooling water, avoiding the problem of the cooling water and the oil being discharged together and being inconvenient to handle.

[0042] Reference Figure 1-7 The present invention also provides an embodiment: a method for using a cooling device for a CNC machine tool, comprising the following steps:

[0043] S1: First, add an appropriate amount of cooling water to the interior of the liquid storage tank 3. The cooling water passes through the filter plate 7 and the square hose 4 and enters the interior of the pump box 5. The cooling water is then pumped out by the water pump 6 to cool the processed parts inside the CNC machine tool. The cooling water then passes through the CNC machine tool to coarsely filter out debris and then flows back to the interior of the liquid storage tank 3. When the liquid storage tank 3 is used for a long time, the cooling water inside it will deteriorate and its cooling effect will be greatly reduced. When the liquid storage tank 3 needs to be cleaned regularly, execute S2;

[0044] S2: The water pump 6 pumps out the cooling water inside the pump box 5 and the liquid storage tank 3, so that it cannot flow back into the liquid storage tank 3, and then rotates the adjusting screw 22 counterclockwise. The adjusting screw 22 drives the slider 21 to move upward, and the slider 21 drives the square plate 18 and the sealing gasket 19 to rotate along the hinge through the connecting frame 20. At this time, the chip discharge groove 8 is connected with the liquid storage tank 3, and then the multi-stage electric push rod 14 is started and the telescopic hose 17 is opened. The output end of the multi-stage electric push rod 14 pushes the through pipe 15 and the rotating nozzle 16 to move to the right. The through pipe 15 stretches the telescopic hose 17. After the telescopic hose 17 is opened, the cleaning water inside is sprayed out through the rotating nozzle 16 to flush the impurities and oil attached to the inner wall of the liquid storage tank 3. The impurities and sewage after flushing enter the interior of the chip discharge groove 8, and then the butterfly valve is opened to start the reduction motor 9. The output end of the reduction motor 9 drives the spiral conveying rod 10 to discharge the impurities and sewage. After flushing, the rotating nozzle 16 and the square plate 18 are restored to their original positions and new cooling water can be added for use.

[0045] Working principle: First, add cooling water to the inside of the liquid storage tank 3. When the cooling water triggers the liquid level sensor 34, the liquid level sensor 34 will send a signal to the liquid level display panel 35. At this time, you can stop adding cooling water. The cooling water passes through the filter plate 7 and the square hose 4 and enters the inside of the pump box 5. Then the water pump 6 pumps the cooling water out to cool the processed parts inside the CNC machine tool. Then the cooling water passes through the CNC machine tool to coarsely filter the debris and then flows back to the inside of the liquid storage tank 3. When the liquid storage tank 3 is used for a long time, its interior The cooling water will deteriorate and its cooling effect will be greatly reduced. When the liquid storage tank 3 needs to be cleaned regularly, the float 26 will drive the cross plate 25 and the oil pumping head 27 to float on the surface of the cooling water. The grease flushed from the inside of the CNC machine tool and followed by the reflux will also float on the surface of the cooling water. The oil suction pump 23 is started, and the oil suction pump 23 extracts the grease floating on the surface of the cooling water through the oil suction pipe 24 and the oil pumping head 27. After the grease is extracted, the oil suction pump 23 is turned off and the water pump 6 is started. The water pump 6 pumps the pump box 5 and the storage tank 3. The cooling water inside the liquid tank 3 is extracted, so that it cannot flow back into the interior of the liquid storage tank 3, and then the adjusting screw 22 is rotated counterclockwise, and the adjusting screw 22 drives the slider 21 to move upward, and the slider 21 drives the square plate 18 and the sealing gasket 19 to rotate along the hinge through the connecting frame 20. At this time, the chip discharge groove 8 is connected with the liquid storage tank 3, and then the multi-stage electric push rod 14 is started and the telescopic hose 17 is opened. The output end of the multi-stage electric push rod 14 pushes the through pipe 15 and the rotating nozzle 16 to move to the right, and the through pipe 15 stretches the telescopic hose 17. After the telescopic hose 17 is opened, the cleaning water inside is sprayed out through the rotating nozzle 16 to flush the impurities and oil attached to the inner wall of the liquid storage tank 3. The impurities and sewage after flushing enter the interior of the chip discharge groove 8 through the guidance of the guide plate 30, and then the butterfly valve is opened to start the reduction motor 9. The output end of the reduction motor 9 drives the spiral conveying rod 10 to discharge the impurities and sewage. After flushing, the rotating nozzle 16 and the square plate 18 are restored to their original positions and new cooling water can be added for use.

After the telescopic hose (17) is opened, the cleaning water inside is sprayed out through the rotating nozzle (16) to wash the impurities and oil stains attached to the inner wall of the liquid storage tank (3). The impurities and sewage after washing enter the inside of the chip discharge groove (8), and then the butterfly valve is opened to start the reduction motor (9). The output end of the reduction motor (9) drives the spiral conveying rod (10) to discharge the impurities and sewage. After the washing is completed, the rotating nozzle (16) and the square plate (18) are restored to their original positions and new cooling water can be added for use.
