Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1 to 5 This utility model provides a technical solution: a cutting fluid return and slag collection device for a CNC machine tool, comprising: a movable frame 1; a top support frame 2 bolted to the top of the movable frame 1, with a first filter screen 3 disposed on the inner side of the top support frame 2; an inner support frame 10 fixedly connected to the inner side of the movable frame 1, with a fluid tank 4 fixedly connected inside the inner support frame 10; a second filter screen 5 disposed inside the fluid tank 4, with a slag discharge port 6 opened inside the fluid tank 4; and a sealing plate 12 slidably disposed inside the fluid tank 4 to seal it. Plate 12 is matched with slag discharge port 6; inner scraper 7 is slidably set inside liquid tank 4; recovery box 15 is installed inside moving frame 1 by bolts, and a mounting cover 24 is installed on the top of recovery box 15, and a second liquid outlet pipe 22 is set on the top of mounting cover 24; bottom drain tee 19 is fixed to the bottom of liquid tank 4, one end of the second liquid outlet pipe 22 is connected to bottom drain tee 19, and a first liquid outlet pipe 21 is set on one end of bottom drain tee 19, and the first liquid outlet pipe 21 is connected to moving frame 1.

[0027] It should be noted that, in this embodiment, when the device is working, the cutting fluid generated by the CNC machine tool first enters the top support frame 2. The first filter screen 3 installed inside the top support frame 2 performs preliminary filtration of the cutting fluid, intercepting larger impurity particles to prevent them from entering subsequent structures and causing blockages or affecting the recovery quality. The cutting fluid that has undergone preliminary filtration flows into the liquid tank 4. After entering the liquid tank 4, the second filter screen 5 installed inside the liquid tank 4 performs secondary filtration of the cutting fluid, further removing smaller impurities and making the cutting fluid purer. The filtered cutting fluid enters the second outlet pipe 22 through the bottom drain tee 19, and then enters the mounting cover 24 and the recovery tank 15 through the second outlet pipe 22. The waste is stored and processed through the recycling bin 15. When a certain amount of impurities accumulates in the liquid tank 4 and slag needs to be discharged, the control valve 20, which is matched with the second liquid outlet pipe 22, is closed, and the control valve 20, which is matched with the first liquid outlet pipe 21, is opened. The external controller controls the cylinder 13 to start, and the output end of the cylinder 13 pushes the sealing plate 12 to slide in the liquid tank 4. Since the sealing plate 12 matches the slag discharge port 6, and the four limit rods 14 symmetrically fixed on one side of the sealing plate 12 are slidably connected to the top fixed support plate 11, the limit rods 14 play a guiding and limiting role, ensuring that the sealing plate 12 moves smoothly and accurately, thereby precisely controlling the opening of the slag discharge port 6. The external controller controls the linear module 8 to start, and the linear... Module 8 includes a bracket for mounting guide rails, a movable slide table that slides on the guide rails, a lead screw system consisting of a lead screw and a nut, and a servo motor that drives the lead screw. The servo motor drives the lead screw to rotate, and the lead screw and nut convert the rotational motion into linear motion, driving the movable slide table to perform linear reciprocating motion on the guide rails. An outer sliding frame 9 is mounted on the movable slide table, and the outer sliding frame 9 is slidably connected to the liquid tank 4. The inner side of the outer sliding frame 9 is fixedly connected to the inner scraper 7. When the linear module 8 moves the outer sliding frame 9, the inner scraper 7 slides within the liquid tank 4 to scrape away impurities on the second filter screen 5. The impurities in the second filter screen 5 are discharged through the slag discharge port 6, and the slag discharge guide frame 23 discharges the impurities. Impurities are accurately guided to the designated location for easy collection and treatment. After the slag is discharged, the cylinder 13 drives the sealing plate 12 to reset and seal the slag discharge port 6 to prevent cutting fluid leakage. When the liquid tank 4 and the second filter screen 5 need to be thoroughly cleaned, the second filter screen 5 is cleaned with cleaning fluid. The cleaning fluid enters the collection bucket 17 and the filter screen 18 through the bottom drain tee 19 and the first outlet pipe 21 for drainage treatment. When the cutting fluid needs to be recovered to the recovery tank 15, the material control valve 20 connected to the second outlet pipe 22 is opened and the material control valve 20 connected to the first outlet pipe 21 is closed. The treated cutting fluid in the liquid tank 4 flows into the recovery tank 15 through the second outlet pipe 22.

[0028] The specific architecture and operation logic of the cylinder 13 and the linear module 8 in this application, which achieve coordinated control through an external controller, are consistent with the existing technology in this field, and will not be discussed in detail here.

[0029] The linear module 8 includes a bracket for mounting guide rails, a movable slide table that slides on the guide rails, a lead screw system consisting of a lead screw and a nut, and a servo motor that drives the lead screw. The nut is connected to the movable slide table, and the servo motor drives the lead screw to rotate. The rotation is converted into linear motion by the lead screw and nut, which drives the slide table to move. It is also equipped with a bellows cloth / protective cover to protect internal components from dust and impurities, extend service life, and ensure operating accuracy. The helical motion of the lead screw and nut can convert rotational motion into linear motion, which drives the lead screw to rotate through the servo motor. The lead screw drives the movable slide table to move on the guide rails.

[0030] In one embodiment, such as Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, a top fixed support plate 11 is bolted to the top of the inner support frame 10. A cylinder 13 is bolted to one side of the top fixed support plate 11. The output end of the cylinder 13 is fixedly connected to the sealing plate 12. Four limiting rods 14 are symmetrically fixed to one side of the sealing plate 12. The limiting rods 14 are slidably connected to the top fixed support plate 11.

[0031] It should be noted that in this embodiment, by setting a top fixed support plate 11 on the top of the inner support frame 10 and installing a cylinder 13 on it, the output end of the cylinder 13 is fixedly connected to the sealing plate 12. The cylinder 13 can be used to precisely control the movement of the sealing plate 12, thereby controlling the opening and closing of the slag discharge port 6, facilitating slag discharge and avoiding cutting fluid leakage and impurity residue.

[0032] In one embodiment, such as Figures 1 to 5 As shown, linear modules 8 are bolted to both sides of the liquid tank 4. An outer sliding frame 9 is mounted on the moving slide of the linear module 8. The outer sliding frame 9 is slidably connected to the liquid tank 4, and the inner side of the outer sliding frame 9 is fixedly connected to the inner scraper 7.

[0033] It should be noted that in this embodiment, linear modules 8 are installed on both sides of the liquid tank 4, and an outer sliding frame 9 is installed on its moving slide. The inner side of the outer sliding frame 9 is fixedly connected to the inner scraper 7. The linear modules 8 can drive the outer sliding frame 9 to make linear reciprocating motion along the liquid tank 4, thereby causing the inner scraper 7 to slide on the inner wall of the liquid tank 4, effectively scraping off the cutting fluid residue and impurities attached to the inner wall, improving the cleanliness of the liquid tank 4, and ensuring the quality of cutting fluid recovery.

[0034] In one embodiment, such as Figures 1 to 4 As shown, a collection bucket 17 is provided on the mobile frame 1. A filter screen 18 is provided inside the collection bucket 17. A drain pipe is provided at the bottom of the collection bucket 17. The first drain pipe 21 is matched with the collection bucket 17.

[0035] It should be noted that in this embodiment, the liquid used for cleaning the second filter screen 5 and the liquid tank 4 is discharged through the first liquid outlet pipe 21, and the liquid used for cleaning and maintenance can be filtered through the filter screen 18.

[0036] In one embodiment, such as Figures 1 to 5 As shown, a drain valve 25 is provided on one side of the recovery tank 15, and a liquid guide frame 16 that cooperates with the drain valve 25 is fixedly connected to one side of the recovery tank 15. A slag discharge guide frame 23 that cooperates with the slag discharge port 6 is fixedly connected to the bottom of the liquid tank 4.

[0037] It should be noted that, in this embodiment, a drain valve 25 and a liquid guide frame 16 are provided on one side of the recovery tank 15. By controlling the opening and closing of the drain valve 25, the treated cutting fluid in the recovery tank 15 can be discharged in an orderly manner. The liquid guide frame 16 can guide the cutting fluid to be discharged accurately, avoid cutting fluid leakage, and keep the working environment clean.

[0038] In one embodiment, such as Figures 1 to 4 As shown, two control valves 20 are symmetrically installed on the bottom drain tee 19, and four casters are provided at the bottom of the moving frame 1.

[0039] It should be noted that in this embodiment, two control valves 20 are symmetrically installed on the bottom drain tee 19. By controlling the opening and closing of the two control valves 20, the flow direction of the cutting fluid between the first outlet pipe 21 and the second outlet pipe 22 can be flexibly adjusted.
