Through the filtering and recycling mechanism, the recycling of the coolant is realized, which not only reduces the production cost, but also improves the processing efficiency and production benefits.

[0033] Further, such as Figures 1 to 4As shown, the liquid collecting assembly includes a baffle 8 fixedly connected to the upper end of the elbow 7, the baffle 8 is inclined, and drainage grooves 12 are provided on both sides of the middle of the upper end surface of the baffle 8, and one end of the two drainage grooves 12 is opened to the inside of the baffle 8, and a circular ring 9 is fixedly connected to the upper end surface of the baffle 8.

[0034] During the cutting operation, the coolant is sprayed onto the drill bit 32 and the processing area under the action of the spray assembly. During processing, the drill bit 32 penetrates the rim and the coolant flows to the inside of the bent pipe 7. Part of the coolant falls to the edge of the rim. The inclined baffle 8 effectively guides the flow of the coolant. The drainage groove 12 thereon guides the coolant into the inside of the circular ring 9. The circular ring 9 is close to the inner diameter of the rim to ensure that the coolant does not overflow. The slide groove 10 on the inner wall of the circular ring 9 is equipped with a filter frame 14. The filter on the filter frame 14 intercepts impurities and particulate matter in the coolant. The operator can easily lift the filter frame 14 by the handle 15 for cleaning or replacement. The coolant that has been initially filtered flows into the curved pipe 7 and is collected through the central groove 11 on the fixed seat 4. Subsequently, the coolant is guided by the inclined drain pipe 6 and uses its gravity to smoothly flow to the liquid storage tank 3. The liquid inlet 5 on the top of the liquid storage tank 3 can be used to add new coolant, and the lower connecting pipe 30 at the lower end is used to re-transport the filtered coolant to the spray assembly to achieve the recycling of the coolant.

[0035] Further, such as Figure 1 , Figures 5 to 7As shown, the spray assembly includes a fixed ring 29 fixedly connected to the end face of the mounting plate 34 away from the servo motor 17, the upper and lower ends of the fixed ring 29 are fixedly connected with nozzles 31, one end of the two nozzles 31 extending out of the fixed ring 29 is fixedly connected to the connecting frame 20, the upper end face of the connecting frame 20 is fixedly connected to the upper connecting pipe 19, the upper connecting pipe 19 is U-shaped, the middle part of the front end face of the fixed frame 16 is fixedly connected with a bracket 18, the front end of the bracket 18 is fixedly connected to the side of the upper connecting pipe 19 away from the connecting frame 20, the end of the upper connecting pipe 19 away from the connecting frame 20 is fixedly connected with a bellows 35, the lower end of the bellows 35 is fixedly connected to the upper end of the lower connecting pipe 30, the upper connecting pipe 19 is connected to the lower connecting pipe 30 through the bellows 35, the outer wall of the drill bit 32 is fixedly connected to the end close to the mounting plate 34 with a driving pulley 25, the driving pulley The outer transmission of the pulley 25 is connected with a belt 26, and the upper end of the belt 26 is connected with a driven pulley 27 for transmission. A rotating rod 28 is fixedly connected to the middle of the end surface of the driven pulley 27 away from the mounting plate 34. One end of the rotating rod 28 extends into the interior of the upper connecting tube 19 and is fixedly connected to a rotating wheel 33. The end of the driven pulley 27 away from the rotating rod 28 is rotatably connected to the upper end of the mounting plate 34. The end surface of the fixed ring 29 away from the mounting plate 34 is fixedly connected to a telescopic sleeve 23. One end of the telescopic sleeve 23 is fixedly connected to a bonding plate 22. The bonding plate 22 is arc-shaped. Both ends of the end surface of the bonding plate 22 close to the mounting plate 34 are fixedly connected to limit springs 21. The ends of the two limit springs 21 away from the bonding plate 22 are fixedly connected to the mounting plate 34. The inner wall of the fixed ring 29 is located on one side of the active pulley 25 and is fixedly connected to a partition plate 24.

[0036] When the servo motor 17 drives the drill bit 32 to rotate for cutting, the active pulley 25 on the outer wall of the drill bit 32 rotates accordingly, and is transmitted to the driven pulley 27 through the belt 26, thereby driving the rotating rod 28 and the rotating wheel 33 at its end to rotate in the upper connecting pipe 19. This rotational movement, through the structural design of the connecting frame 20 and the two nozzles 31, pressurizes the coolant stored in the liquid storage tank 3 and transported to the upper connecting pipe 19 through the lower connecting pipe 30 and the bellows 35, and guides it to the nozzle 31. At the same time, the nozzle 31 is located at the upper and lower ends of the fixing ring 29, and the fixing ring 29 is connected to the bonding plate 22 through the telescopic sleeve 23. The arc-shaped design can fit closely to the processing surface to prevent coolant from splashing. The limit spring 21 provides elastic support for the telescopic sleeve 23, so that it can be fine-tuned according to changes in the processing surface to ensure a close fit. In addition, the setting of the partition 24 effectively prevents the coolant from directly entering the rotating area of ​​the drill bit 32, reducing the interference of the coolant on the movement of the drill bit 32. Therefore, with the rotation of the drill bit 32 and the transmission of the pulley and belt 26, the spray assembly can stably and evenly spray coolant to the drill bit 32 and the processing area, thereby realizing real-time cooling of the drill bit 32, improving processing efficiency and quality, and ensuring the cleanliness and safety of the working environment.
