Description

Technical Field

[0001] This utility model relates to the field of cooling device technology, specifically a cooling device for a CNC lathe. Background Technology

[0002] A CNC lathe is an automated machine tool controlled by a computer program. It uses pre-programmed G-code instructions to drive cutting tools to perform precision machining on rotating workpieces. It can efficiently complete complex processes such as turning, drilling, and threading, and is characterized by high precision, high repeatability, and flexible production. It is widely used in machinery manufacturing, automotive, aerospace, and other fields. Its core consists of a CNC system, spindle, turret, and bed. Functionally, it can be divided into ordinary CNC lathes, turning-milling centers, etc., significantly improving production efficiency and machining quality.

[0003] When machining workpieces on a CNC lathe, the cutting tool generates high temperatures during continuous machining, requiring coolant for cooling. However, waste debris is mixed into the coolant during machining, rendering it unusable. Existing cooling devices cannot directly recover the coolant and separate the waste debris.

[0004] In view of this, we propose a cooling device for CNC lathes. Utility Model Content

[0005] The purpose of this utility model is to provide a cooling device for CNC lathes, which solves the problem that the cooling device cannot recycle and separate internal waste.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A cooling device for a CNC lathe includes a connecting platform and a fixture platform. The fixture platform is fixedly connected to the connecting platform via a connector. A cooling box is provided at the bottom of the connecting platform, and the cooling box is fixedly connected to the connecting platform via bolts. The device also includes a recovery section for recovering and filtering coolant, and a cooling section for repeatedly spraying and cooling the coolant recovered by the recovery section. The recovery section includes a semi-gear ring located inside the connecting platform and rotatably connected to it. A rotating shaft passes through and is rotatably connected to the inner side of the connecting platform. A connecting rod is fixedly connected to the surface of the rotating shaft. The end of the connecting rod away from the rotating shaft is fixedly connected to the inner side of the semi-gear ring. A brush is fixedly connected to the bottom surface of the connecting rod. A turntable is fixedly connected to the top of the rotating shaft. A brush rod is fixedly connected to the side of the turntable. A recovery groove is formed on the top surface of the connecting platform, and a recovery hole is formed on the inner side of the recovery groove.

[0008] Preferably, a motor is fixedly connected to the surface of the connecting platform, and a half-tooth pinion is fixedly connected to the output shaft of the motor, the half-tooth pinion meshing with a half-gear ring.

[0009] Preferably, a fixing box is fixedly connected to the inner wall of the connecting platform, and the rotating shaft passes through the fixing box and is rotatably connected.

[0010] Preferably, a spiral spring is fixedly connected between the surface of the rotating shaft and the inner wall of the fixed box.

[0011] Preferably, a screen is fixedly connected to the inside of the cooling box, and the bottom end of the brush is in contact with the top surface of the screen.

[0012] Preferably, the cooling section includes an electric push rod, the bottom end of which is fixedly connected to the top surface of the connecting platform, the output end of which is fixedly connected to a high-pressure spray gun, and the top surface of the connecting platform is fixedly connected to a water pump.

[0013] Preferably, the top end of the water pump is connected to the high-pressure spray gun via a connecting pipe, and the bottom end of the water pump is connected to the cooling tank via a connecting pipe.

[0014] By employing the above technical solution, this utility model provides a cooling device for CNC lathes. It possesses at least the following beneficial effects:

[0015] 1. This utility model utilizes a semi-gear pinion to drive a meshing semi-gear ring to rotate. When the semi-gear ring rotates, it drives a rotating shaft to rotate via a connecting rod. When the rotating shaft rotates, it coils a spiral spring, which in turn drives a turntable to rotate. As the turntable rotates, it causes a brush rod to scrape within the recovery tank, drawing coolant through the recovery tank and recovery holes into a screen, where it is then recycled back into the cooling tank. After the semi-gear pinion drives the semi-gear ring to rotate to a certain extent, the semi-gear ring no longer meshes with the pinion. The coiled spiral spring then drives the rotating shaft to reverse, allowing the brush rod to swing back and forth to clean the recovery tank. This cooling system allows for the repeated use of coolant, preventing resource waste.

[0016] 2. In this utility model, after the half-gear ring rotates to a certain extent driven by the half-gear pinion, the half-gear ring no longer meshes with the half-gear pinion. Then, the coiled spiral spring will drive the rotating shaft to reverse, so that the brush rod can swing back and forth to clean the recycling tank. At the same time, the brush at the bottom of the connecting rod can also repeatedly move the waste on the screen to avoid screen blockage and affect the flow of coolant. Attached Figure Description

[0024] 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.

[0025] A cooling device for a CNC lathe, such as Figures 1-5As shown, the system includes a connecting platform 1 and a clamping platform 4. The clamping platform 4 is fixedly connected to the connecting platform 1 via a connector. A cooling box 5 is provided at the bottom of the connecting platform 1 and is fixedly connected to the connecting platform 1 via bolts. It also includes a recovery section 2 for recovering and filtering the coolant; and a cooling section 3 for repeatedly spraying and cooling the coolant recovered by the recovery section 2. The recovery section 2 includes a half-gear ring 23, which is located inside the connecting platform 1 and rotatably connected to it. A rotating shaft 26 passes through and rotatably connects to the inner side of the connecting platform 1. A connecting rod 24 is fixedly connected to the surface of the rotating shaft 26. The end of the connecting rod 24 away from the rotating shaft 26 is fixedly connected to the inner side of the half-gear ring 23. A brush 25 is fixedly connected to the bottom surface of the connecting rod 24, and a turntable 27 is fixedly connected to the top of the rotating shaft 26. A brush rod 28 is fixedly connected to the side of the turntable 27. After the half-tooth pinion 22 drives the half-gear ring 23 to rotate to a certain extent, the half-gear ring 23 no longer meshes with the half-tooth pinion 22. Then, the coiled spiral spring 212 will drive the rotating shaft 26 to reverse, so that the brush rod 28 can swing back and forth to clean the recycling tank 29. At the same time, the brush 25 at the bottom of the connecting rod 24 can also repeatedly agitate the waste on the screen 213 to prevent the screen 213 from clogging and affecting the flow of coolant. A recycling tank 29 is provided on the top surface of the connecting platform 1, and a recycling hole 210 is provided on the inner side of the recycling tank 29. A motor 21 is fixedly connected to the surface of the connecting platform 1, and a half-tooth pinion 22 is fixedly connected to the output shaft of the motor 21. The half-tooth pinion 22 meshes with the half-gear ring 23. A fixed box 211 is fixedly connected to the inner wall of the cavity of the connecting platform 1, and a rotating shaft 26 passes through the fixed box 211 and is rotatably connected thereto. A spiral spring 212 is fixedly connected between the surface of the rotating shaft 26 and the inner wall of the fixed box 211. When the motor 21 is started, the output shaft of the motor 21 drives the half-tooth pinion 22 to rotate. The half-tooth pinion 22 drives the half-gear ring 23 that meshes with it to rotate as well. When the half-gear ring 23 rotates, it drives the rotating shaft 26 to rotate through the connecting rod 24. When the rotating shaft 26 rotates, it will coil the spiral spring 212. A screen 213 is fixedly connected to the inside of the cooling box 5. When the rotating shaft 26 rotates, it will rewind the spiral spring 212. At the same time, the rotating shaft 26 will drive the turntable 27 to rotate together. When the turntable 27 rotates, it will drive the brush rod 28 to scrape in the recovery tank 29. The coolant will fall into the screen 213 through the recovery tank 29 and the recovery hole 210 and be recycled back into the cooling box 5 through the screen 213. The bottom end of the brush 25 is in contact with the top surface of the screen 213.

[0026] The cooling unit 3 includes an electric push rod 31. The bottom end of the electric push rod 31 is fixedly connected to the top surface of the connecting platform 1. A high-pressure spray gun 32 is fixedly connected to the output end of the electric push rod 31. A water pump 33 is fixedly connected to the top surface of the connecting platform 1. The top end of the water pump 33 is connected to the high-pressure spray gun 32 through a connecting pipe, and the bottom end of the water pump 33 is connected to the cooling tank 5 through a connecting pipe. When the water pump 33 is started, it draws coolant from the cooling tank 5 through the connecting pipe and sprays it out through the high-pressure spray gun 32. The height and position of the high-pressure spray gun 32 can be adjusted by starting the electric push rod 31 to adapt to the workpiece being processed.

[0027] In use, the cooling device for a CNC lathe of this utility model involves first injecting coolant into the cooling tank 5, then connecting the cooling tank 5 to the connecting platform 1 with bolts, and finally fixing the connecting platform 1 to the inner side of the CNC lathe. When machining the workpiece on the fixture table 4, the water pump 33 is started, which draws the coolant from the cooling tank 5 through the connecting pipe and sprays it out through the high-pressure spray gun 32. The height and position of the high-pressure spray gun 32 can be adjusted by activating the electric push rod 31 to adapt to the workpiece being machined. After the coolant is sprayed out by the high-pressure spray gun 32, it falls into the recovery tank 29. Then, the motor 21 is started, and the output shaft of the motor 21 drives the half-tooth pinion 22 to rotate. The half-tooth pinion 22 drives the half-gear ring 23 that meshes with it to rotate as well. When rotating, the connecting rod 24 drives the rotating shaft 26 to rotate. When the rotating shaft 26 rotates, it will coil the scroll spring 212. At the same time, the rotating shaft 26 will drive the turntable 27 to rotate as well. When the turntable 27 rotates, it will drive the brush rod 28 to scrape in the recovery tank 29, so that the coolant falls into the screen 213 through the recovery tank 29 and the recovery hole 210 and is recycled back into the cooling box 5 through the screen 213. After the half-tooth pinion 22 drives the half-gear ring 23 to rotate to a certain extent, the half-gear ring 23 no longer meshes with the half-tooth pinion 22. Then the coiled scroll spring 212 will drive the rotating shaft 26 to reverse, so that the brush rod 28 can swing back and forth to clean the recovery tank 29. At the same time, the brush 25 at the bottom of the connecting rod 24 can also repeatedly move the waste on the screen 213 to prevent the screen 213 from being blocked and affecting the passage of coolant.
