[0025] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0026] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0027] Example 1

[0028] like Figures 1-6As shown, a water spray cooling device for a CNC machine tool includes: a CNC machine tool body 1, a water tank 11 is provided at the bottom of the machining area of ​​the CNC machine tool body 1, a filter screen 12 is fixedly connected to the inner wall of the water tank 11, and two equipment doors 13 are provided on the front side of the CNC machine tool body 1; a cleaning component is provided on the inner wall of the water tank 11 for cleaning debris from the top of the filter screen 12; and a cooling component is provided at the bottom of the water tank 11 for cooling the water inside the water tank 11.

[0029] The CNC machine tool body 1 has two tracks 4 fixedly connected to the bottom of the machining area. The two tracks 4 are respectively equipped with a cutting tool 41 and a top tool 42. The cutting tool 41 is fixedly connected with a mounting rod 43. The bottom of the water tank 11 is equipped with a water pump 44. A water supply pipe 45 is fixedly connected to one side of the water pump 44. A drag chain 46 is fixedly installed on the top of the machining area of ​​the CNC machine tool body 1. A water outlet 47 is installed on the mounting rod 43. One end of the water supply pipe 45 passes through the drag chain 46 and is connected to one end of the water outlet 47.

[0030] When processing a workpiece, the workpiece is placed in the processing area of ​​the CNC machine tool body 1. The workpiece is fixed by a fixture and an ejector tool 42. The workpiece is processed by a cutting tool 41. During processing, a water pump 44 is turned on, pumping water from the water tank 11 into a water delivery pipe 45. The water is then delivered to a water outlet 47 through the water delivery pipe 45, where it is sprayed out to cool the workpiece. The drag chain 46 facilitates the movement of the water delivery pipe 45, and the outflowing water flows back into the water tank 11. The filter screen 12 filters the water and intercepts debris generated during processing. The cleaning component cleans the debris from the filter screen 12, collecting the debris and preventing it from clogging the mesh of the filter screen 12, which would affect filtration and cause water to overflow from the water tank 11. Furthermore, the cooling component cools the water, preventing the cooling water temperature from becoming too high and affecting the cooling effect.

[0031] Example 2

[0032] Based on Embodiment 1, the cleaning assembly includes: mounting groove 2, roller 21, transmission belt 22, connecting rod 23, scraper 24 and drive motor 25. Mounting groove 2 is provided on the inner walls of opposite sides of the water tank 11 near the top of the filter screen 12. Rollers 21 are rotatably connected to the inner walls of the mounting groove 2 near the opposite ends, and transmission belt 22 is connected between the two rollers 21. Connecting rod 23 is connected between the two opposite rollers 21. Multiple scrapers 24 are fixedly connected between the two transmission belts 22 and are evenly distributed on the transmission belts 22. Drive motor 25 is fixedly installed inside one of the mounting grooves 2. One end of the drive shaft of drive motor 25 is connected to one of the rollers 21. A collection chamber 26 is provided inside the CNC machine tool body 1. A loading frame 27 is provided inside the collection chamber 26. A feed inlet 28 is provided between the collection chamber 26 and the water tank 11.

[0033] When cleaning debris from the filter screen 12, the drive motor 25 is started to drive the connected roller 21 to rotate, which in turn drives the transmission belt 22 to move. The connecting rod 23 can drive the two opposing rollers 21 to rotate synchronously, and then the two transmission belts 22 drive the scraper 24 to move smoothly. When the scraper 24 moves, it scrapes the debris on the filter screen 12 towards the feed inlet 28. The debris enters the collection chamber 26 through the feed inlet 28 and falls into the loading frame 27 to collect the debris. This avoids the debris from clogging the mesh of the filter screen 12 and makes it easier to collect the debris.

[0034] Example 3

[0035] Based on Embodiment 1, the cooling component includes: a support frame 3, a heat absorption plate 31, an air duct 32, an equipment cavity 33, and an exhaust fan 34. Two support frames 3 are fixedly installed at the bottom of the water tank 11. Several heat absorption plates 31 are evenly distributed between the two support frames 3. Air ducts 32 are connected to the heat absorption plates 31. An equipment cavity 33 is opened inside the CNC machine tool body 1 near the water tank 11. An exhaust fan 34 is fixedly installed inside the equipment cavity 33. An exhaust pipe 35 is fixedly connected to the input end of the exhaust fan 34. One end of the exhaust pipe 35 extends into the water tank 11 and is connected to the output end of the air duct 32. An air inlet pipe 36 is provided inside the equipment cavity 33. One end of the air inlet pipe 36 extends into the water tank 11 and is connected to the input end of the air duct 32. The other end of the air inlet pipe 36 is connected to the outside.

[0036] During use, the heat absorption plate 31 absorbs the heat from the water and transfers it to the air duct 32. The exhaust fan 34 is started to draw out the air. Fresh air enters from the air inlet pipe 36 and flows along the air duct 32. One end of the air inlet pipe 36 is connected to the outside of the back of the CNC machine tool body 1. Fresh air enters the air inlet pipe 36 from the back. The flowing air carries away the heat from the air duct 32 and then exits from the exhaust pipe 35 into the exhaust fan 34. The hot air is then discharged from the output end of the exhaust fan 34. The hot air is sprayed out from the front to avoid the coolant temperature from being too high and affecting the processing efficiency.
