[0035] Reference Figure 3 And Figure 4The outer wall of the processing box 7 is fixedly connected with a metal chip falling channel 18 on both sides. The metal chip falling channel 18 is a transmission channel for metal chips, and is made of stainless steel to ensure that it will not be damaged due to wear or corrosion of metal chips during long-term use. The metal chip falling channel 18 is L-shaped, and the inner wall thereof is finely polished to enable metal chips to be quickly and unobstructively transmitted therein. The inner wall of the chute 10 is provided with a chip inlet 11. The chip inlet 11 is the first entrance for metal chips to enter the cleaning system, and is rectangular in shape. The edges thereof are rounded to prevent metal chips from being scraped and retained when entering. The inner wall of the chip inlet 11 is smooth, which can effectively reduce the friction of metal chips when entering, so that they can flow in smoothly. The chip inlet 11 is in communication with the metal chip falling channel 18. The bottom surface of the table plate 1 is fixedly connected with a connecting block 28. The bottom of the connecting block 28 is fixedly connected with a negative pressure machine 20. The negative pressure machine 20 is the power core of the entire metal chip cleaning system. A high-performance centrifugal fan structure is arranged in the negative pressure machine 20. The impeller is driven by a motor to rotate at a high speed, thereby forming a strong negative pressure suction at the air inlet. The negative pressure machine 20 has a regular cuboid shape. The two sides of the negative pressure machine 20 are fixedly connected with filter screen plates 21. The filter screen plates 21 are components for intercepting and collecting metal chips. They can effectively block most metal chips to prevent them from entering the negative pressure machine 20, thereby protecting the normal operation of the negative pressure machine 20. The filter screen plates 21 are rectangular plates, and the size thereof is adapted to the size of the side surface of the negative pressure machine 20. The filter screen plates 21 are fixed on the two sides of the negative pressure machine 20 by bolts to ensure that they will not be loosened or displaced during the adsorption of metal chips. The bottom of the negative pressure machine 20 is slidably connected with a chip collecting box 22. The chip collecting box 22 is a container for collecting scraped metal chips. It has a cuboid shape, and a slide rail matching the bottom of the negative pressure machine 20 is arranged at the top of the chip collecting box 22 to facilitate the extraction and insertion of the chip collecting box 22. The top of the metal chip falling channel 18 is fixedly connected with a protective shell 19. The protective shell 19 is a protective device for accommodating components such as a second driving motor 23 and a rotating shaft 24. The left and right sides of the inner wall of the protective shell 19 are fixedly connected with the second driving motor 23. The output end of the second driving motor 23 is fixedly connected with the rotating shaft 24. The rotating shaft 24 is a component for driving the connection belt 25 to move. The other end of the rotating shaft 24 is rotatably connected to the inner wall of the protective shell 19. The connection belt 25 is arranged between the rotating shafts 24. The connection belt 25 is a transmission component for connecting the rotating shaft 24 and the connecting rod 26. The outer wall of the connection belt 25 is fixedly connected with the connecting rod 26. The bottom of the connecting rod 26 is fixedly connected with a scraper 27. The scraper 27 is a component for directly cleaning metal chips on the filter screen plate 21. It is made of rubber material and has a certain hardness and wear resistance. The surface friction of the filter screen plate 21 is moderate, and it will not scratch the filter screen plate 21.

[0036] Specifically, during the drilling process, as the drilling machine 6 performs accurate drilling operations on the metal plate, a large amount of metal debris will inevitably be generated. If these metal debris are not cleaned in time, not only will it affect the drilling accuracy, but also it may cause many adverse effects on the normal operation of the equipment. Therefore, it is crucial to clean the metal debris inside the equipment efficiently. At this time, the negative pressure machine 20 at the bottom of the table plate 1 starts to work. Under the action of negative pressure, the metal debris will first enter the chip inlet 11 on both sides of the inner wall of the processing box 7. The metal debris enters the chip falling channel 18 through the chip inlet 11 and is finally adsorbed on the surface of the filter screen plate 21 on both sides of the negative pressure machine 20. When there are more metal debris on the surface of the filter screen plate 21, the driving motor 23 in the protective shell 19 on the top of the chip falling channel 18 drives the rotating shaft 24 to rotate. The rotating shaft 24 rotates around its axis. The rotation of the rotating shaft 24 causes the connecting belt 25 to displace and transmit power to the connecting rod 26, which drives the scraper 27 to displace. The moving direction of the scraper 27 is the same as the displacement direction of the connecting rod 26. During the movement, one end of the scraper 27 is in contact with the surface of the filter screen plate 21. Through the friction and pushing force of the scraper 27, the metal debris on the filter screen plate 21 is scraped off. The metal debris will enter the chip collection box 22 through the opening at the bottom under the action of gravity, realizing the collection of metal debris and achieving the effect of efficiently cleaning the metal debris inside the equipment, ensuring the normal operation of the equipment and prolonging the service life of the equipment. At the same time, it also helps to maintain the accuracy and efficiency of the drilling operation.

[0037] Working principle: when using the metal material surface precision drilling assembly, first the staff will be required to place the metal plate in the processing box 7 inside the storage plate 8 above, at this time the drive motor one 14 at the bottom of the processing box 7 drive arm 15 rotation, with the rotation of the drive arm 15 of its two ends of the driven rocker arm 16 also follow the rotation, with the rotation of the driven rocker arm 16, the connecting column 17 in the sliding groove one 9 inner wall sliding displacement, the displacement of the connecting column 17 promotes the activity plate 12 in the sliding groove two 10 inner wall sliding displacement, the displacement of the activity plate 12 promotes the fixture 13 also follow the displacement, the displacement of the fixture 13 makes the metal plate placed above the storage plate 8 is clamped and fixed, so as to achieve the effect of quickly fixing different size metal plate, after the metal plate is fixed, the sliding arm 4 above the support frame 3 on one side of the processing box 7 drive lift 5 horizontal displacement, the lift 5 drive drilling machine 6 up and down displacement, drilling machine 6 on the metal plate precision punching work, a large number of metal chips will be generated in the process of punching, at this time the negative pressure machine 20 at the bottom of the table plate 1 starts to work, produces strong negative pressure, under the action of negative pressure, metal chips will first enter the processing box 7 inner wall both sides of the chip inlet 11, and through the chip inlet 11 into the drop chip channel 18, eventually be adsorbed on the surface of the filter screen plate 21 both sides of the negative pressure machine 20, when there are more metal chips on the surface of the filter screen plate 21, at this time the drive motor two 23 in the protective housing 19 top of the drop chip channel 18 inner wall drive shaft 24 rotation, the rotation of the shaft 24 promotes the connection belt 25 also follow the displacement, the displacement of the connecting belt 25 promotes the connecting rod 26 drive scraper 27 displacement, at this time the scraper 27 one end will be on the surface of the filter screen plate 21 metal chip scraping, metal chips will enter the chip collection box 22 along the bottom of the opening, so as to achieve the effect of high efficiency cleaning equipment inside the metal chip.
