[0034] In the present invention, the oil pumping mechanism includes an oil pump 24 arranged on one side of the bottom surface of the oil chamber and an oil inlet pipe 23 arranged at the oil outlet end of the oil pump 24. A rectangular cavity 37 is opened in the scraper 3, and a plurality of nozzles 38 connected to the rectangular cavity 37 are evenly provided at the bottom of one side of the scraper 3.

[0035] Working principle: When the present invention is used, it includes the following steps:

[0036] Step 1: When the CNC machine tool body 1 is working, the air pump 6 and the oil pump 24 are turned on at the same time. The air in the CNC machine tool body 1 is pumped into the air outlet pipe 5 by the air pump 6, and then enters the dispersion pipe 39 through the air outlet pipe 5. Finally, the air is dispersed in the purification liquid through the air outlet holes on the outer wall of the dispersion pipe 39, thereby removing a large amount of chemical components and powder components in the air in the CNC machine tool body 1, avoiding the air in the CNC machine tool body 1 from being directly discharged into the atmosphere, thereby facilitating the protection of the atmospheric environment;

[0037] Step 2: The oil in the oil chamber is pumped into the oil inlet pipe 23 through the operation of the oil pump 24, and then enters the rectangular cavity 37 in the scraper 3 through the bellows 2. Finally, the oil is sprayed out through the multiple nozzles 38 on one side of the scraper 3, thereby flushing the debris generated on the bottom surface of the CNC machine tool body 1, preventing the debris from affecting the processing of the workpiece, thereby facilitating the improvement of the workpiece processing quality;

[0038] Step 3: As the gas in the filter chamber increases, the gas in the filter chamber passes through the outer mesh frame 10 and the desiccant 9 and enters the inner mesh frame 8, and then enters the sealed cavity 7 through the air guide pipe 11. The air passes through the desiccant 9 and absorbs moisture in the air, preventing the moisture in the air from corroding the CNC machine tool body 1, thereby facilitating the protection of the CNC machine tool body 1 and extending the service life of the CNC machine tool body 1.

[0039] Step 4: When the air in the sealed chamber 7 becomes larger and larger, the pressure at one end of the sealed chamber 7 is greater than the external pressure, causing the piston 12 to move, thereby driving the connecting rod 13, thereby driving the scraper 3 to move. The movement of the scraper 3 facilitates the oil on the bottom surface of the CNC machine tool body 1 to be pushed into the oil chamber, thereby achieving oil cleaning; then the movement of the scraper 3 drives the telescopic rod 16 to move, thereby driving one end of the bending rod A17 to move and rotate, thereby rotating the bending rod B18, and the bending of the bending rod A17 and the bending rod B18 will drive the U-shaped plate 35 and the abutment plate 36 to move downward, thereby bringing The dynamic filter screen 19 moves downward. When the piston 12 moves to the side of the air outlet groove 15, the air outlet groove 15 is located on the side of the piston 12 away from the extrusion spring 14. At this time, the pressure in the sealing chamber 7 is relieved and then reset under the action of the extrusion spring 14, thereby resetting the bent rods A17 and B18, further separating the bent rods A17 and B18 from the U-shaped plate 35 and the abutting plate 36. Then, the filter screen 19 moves up and down under the action of the buffer spring 21, preventing the mesh of the filter screen 19 from being blocked by debris in the oil, thereby improving the working efficiency of the oil filtration.

[0040] Step 5: When the filter screen plate 19 moves downward, the rectangular box 31 will move outward under the action of the wire rope 29, thereby driving the strip brush 33 to move, so as to clean the debris on the filter screen plate 19, thereby facilitating the collection of debris. When the filter screen plate 19 drops to the lowest point, the strip brush 33 just reaches the edges of both sides of the filter screen plate 19, thereby cleaning the debris on the filter screen plate 19; when the filter screen plate 19 moves upward, the rectangular box 31 is reset under the action of the elastic belt 25, thereby cleaning the debris on the filter screen plate 19 into the discharge port A34, and then the debris enters the guide pipe B26 through the guide pipe C27, and finally enters the collection chamber, thereby realizing the collection of debris.

[0041] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
