[0023] Example 1, referring to Figure 1 , Figure 2 and Figure 3 A cooling device for a CNC machine tool includes a worktable 1, a machining box 2 fixedly connected to the upper surface of the worktable 1, an industrial control host 3 fixedly connected to the left side of the machining box 2, a machining component fixedly connected to the upper surface of the machining box 2, two clamping components fixedly connected to the inner bottom wall of the machining box 2, strip grooves opened on both the left and right sides of the machining box 2, a shielding component slidably connected to the inner wall of the strip groove, a machining component including a strip frame 4, a first motor 5 fixedly connected to the left side of the strip frame 4, a lead screw 6 fixedly connected to the output end of the first motor 5, a movable block 7 slidably connected to the inner top wall of the strip frame 4, the movable block 7 being threadedly connected to the lead screw 6, and a machining tool 8 fixedly connected to the lower surface of the movable block 7.

[0024] The first motor 5 can drive the lead screw 6 to rotate, thereby driving the machining tool 8 to move left and right through the movable block 7, which facilitates machining operations on different positions on the workpiece.

[0025] The clamping assembly includes a positioning platform 9, a through hole on the side of the positioning platform 9, a clamping plate 10 slidably connected to the inner wall of the through hole, and an adjusting screw 11 threadedly connected to the upper surface of the positioning platform 9, with the bottom end of the adjusting screw 11 rotatably connected to the upper surface of the clamping plate 10.

[0026] The workpiece is placed under the two clamping plates 10. Rotating the adjusting screw 11 will cause the two clamping plates 10 to descend, thereby pressing the workpiece and ensuring its stability during processing.

[0027] A circulation pump 12 is fixedly connected to the right side of the workbench 1, and a flow divider 13 is fixedly connected to the back of the processing box 2. The input end of the circulation pump 12 is connected to the inside of the workbench 1, and the output end is connected to the inside of the flow divider 13. Two nozzles 14 are fixedly connected to the front of the flow divider 13.

[0028] The circulating pump 12 can deliver the coolant in the worktable 1 to the inside of the distributor 13 and spray it out through the two nozzles 14 on the front of the distributor 13, so that the nozzles 14 can spray the coolant onto the surface of the machining tool 8 and the workpiece, thereby rapidly cooling the machining tool 8 and the workpiece.

[0029] The shielding assembly includes shielding plates 15, with vertical plates 16 fixedly connected to the front of both shielding plates 15. A limiting groove is formed in the inner top wall of the strip groove, and a limiting rod 17 is fixedly connected to the inner wall of the limiting groove. A limiting block 18 is slidably connected to the inner wall of the limiting groove. The limiting block 18 is slidably connected to the surface of the limiting rod 17, and the lower surface of the limiting block 18 is fixedly connected to the upper surface of the shielding plate 15. A transmission plate 19 is fixedly connected to the back of the shielding plate 15, and a rack plate 20 is fixedly connected to the lower surface of the transmission plate 19. Mounting plates 21 are fixedly connected to the left and right sides of the processing box 2. A second motor 22 is fixedly connected to the front of both mounting plates 21. A gear 23 is fixedly connected to the output end of the second motor 22, and the gear 23 meshes with the rack plate 20.

[0030] The second motor 22 can drive the gear 23 to rotate, thereby driving the two baffles 15 to unfold to both sides through the rack plate 20 and the transmission plate 19, which facilitates the loading and unloading of workpieces by the staff. During normal processing, the two baffles 15 can block the front of the processing box 2 to ensure that the coolant sprayed from the nozzle 14 will not splash everywhere, thereby avoiding the waste of coolant and ensuring a clean and tidy workshop.

[0031] Example 2: Refer to Figure 1 and Figure 3A strip-shaped hole is provided on the right side of the workbench 1. A guide frame 24 is fixedly connected to the inner wall of the strip-shaped hole. A rectangular through hole is provided on the side of the guide frame 24. An insert plate 25 is inserted into the inner wall of the rectangular through hole. A fixing hole is provided on the upper surface of the insert plate 25. A screen 26 is fixedly connected to the inner wall of the fixing hole. A positioning frame 27 is fixedly connected to the inner wall of the workbench 1. A slot is provided on the right side of the positioning frame 27. The slot is compatible with the insert plate 25.

[0032] After the coolant cools the cutting tool 8 and the workpiece, it flows back into the worktable 1. At this time, the coolant first comes into contact with the screen 26. The screen 26 can block and collect the waste material carried by the coolant, ensuring that the waste material will not enter the circulation pump 12 and damage it. It has a good protection effect on the circulation pump 12. In addition, the screen 26 can be pulled out through the insert plate 25 for centralized processing of the waste material.

[0033] Working principle: First, the industrial control host 3 turns on the two second motors 22. After the two second motors 22 start, they drive the gear 23 to rotate, which in turn drives the two blocking plates 15 to unfold to both sides through the rack plate 20 and the transmission plate 19. At this time, the operator places the workpiece to be processed under the two clamping plates 10 and rotates the two adjusting screws 11 to lower the two clamping plates 10 to clamp the workpiece. Then, the second motors 22 are started again to return the blocking plates 15 to their original positions, thus blocking the processing box 2. At this time, the first motor 5 drives the movable block 7 to move left and right through the lead screw 6, which drives the processing tool 8 to process the workpiece. After processing, the circulating pump 12 delivers the coolant in the worktable 1 to the distributor 13. The coolant is sprayed onto the machining tool 8 and the workpiece surface through two nozzles 14, thereby quickly cooling down the machining tool 8 and the workpiece to ensure that the quality of the workpiece is not affected by excessive temperature. During the spraying of coolant, the front of the machining box 2 is blocked by two baffles 15, preventing any liquid splashing and ensuring the cleanliness of the workshop. After cooling is completed, the coolant flows back into the worktable 1. At this time, the coolant will carry some waste into the worktable 1. The coolant is blocked by the screen 26, and the waste can remain above the screen 26, while the coolant continues to remain inside the worktable 1, completing the recycling of the coolant and providing a certain degree of protection for the circulation pump 12.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
