[0028] Among them, the water spray pipe 2 is fixedly connected to a first fixed ring 11 located above the second rotating ring 6, and the water spray pipe 2 is fixedly connected to an atomizing fan blade 13. The bottom of the first fixed ring 11 is fixedly connected to multiple fixed rods 12, and the fixed rods 12 cooperate with the limiting slide groove 10 to limit the second rotating ring 6, so that the second rotating ring 6 can rotate within a range, thereby effectively controlling the opening and closing of the water retaining block 9, and preventing the second rotating ring 6 from excessively rotating, thereby affecting the coordination between the multiple water retaining blocks 9 after rotation.

[0029] Among them, the multiple fixed rods 12 are respectively slidably connected to the multiple limiting slide grooves 10 opened below the first fixed ring 11, and the atomizing blades 13 are fixedly connected to the second fixed ring 14. The atomizing blades 13 are fixed to the second fixed ring 14 so that the second fixed ring 14 is in an immovable state, and the second fixed ring 14 is rotatably connected to one end of the multiple water retaining blocks 9, so that when the annular connecting rod 7 drives the water retaining block 9 to move, the water retaining block 9 can be moved along the fixed point between the second fixed ring 14 and the water retaining block 9, so that the water retaining block 9 can be opened and closed to control the atomization state when the water flow is sprayed out.

[0030] Among them, a first water tank 19 is arranged at the bottom of the inside of the CNC machine tool body 1, a second water tank 20 is fixedly connected to one side of the top of the CNC machine tool body 1, a water pipe 17 is fixedly connected to one side of the CNC machine tool body 1, the first water tank 19 and the second water tank 20 are connected to each other through the water pipe 17, the water spray pipe 2 is connected to the second water tank 20, and the first water tank 19 and the second water tank 20 are connected through the water pipe 17, so that the water resources for cooling the workpiece can be recycled through the water pipe 17, thereby realizing water recovery and secondary use, which is easy to cause waste of water resources during use.

[0032] Among them, a filter screen 18 is slidably connected inside the CNC machine tool body 1, and the two sides of the filter screen 18 are slidably matched through I-shaped slots. The filter screen 18 filters the waste chips dropped during processing so that the iron chips cannot fall into the first water tank 19 below and affect the use of the workpiece.

[0033] Among them, a gear ring 16 is fixedly connected to the outer side of the first rotating ring 3, and a gear shaft is meshedly connected to one side of the gear ring 16. A driving motor 15 is fixedly connected to one end of the gear shaft. The driving motor 15 is fixedly connected to the water spray pipe 2. The rotation of the driving motor 15 drives the gear shaft to rotate, and the rotation of the gear shaft drives the gear ring 16 to rotate. The rotation of the gear ring 16 drives the first rotating ring 3 to rotate, thereby controlling the opening and closing of the water retaining block 9.

[0034] Working principle:

[0035] After the workpiece is processed, the first water pump and the second water pump are turned on. The first water pump is started to pump the water in the first water tank 19 to the second water tank 20 through the water pipe 17. The second water pump sprays the water in the second water tank 20 through the water spray pipe 2 to cool the processed workpiece. The water after cooling will pass through the filter 18 and fall into the first water tank 19, so as to circulate and reuse water, thereby reducing the waste of water resources and protecting the ecological environment.

[0036] When the water flows through the water spray pipe 2, the water flows will hit the water retaining block 9 to disperse the water flows, and the water flows that hit and disperse are sprayed out from the water spray pipe 2 again through the dividing point of the atomizing blades 13, so that the atomization degree of the sprayed water flows is further enhanced. When the water flow needs to be concentrated to cool the workpiece, the driving motor 15 is started, and the driving motor 15 rotates with the gear shaft to rotate, and the rotation of the gear shaft drives the gear ring 16 to rotate, and the rotation of the gear ring 16 drives the first rotating ring 3 to rotate, and the rotation of the first rotating ring 3 drives the plurality of connecting rods 5 to rotate, and the rotation of the plurality of connecting rods 5 drives the second rotating ring 6 to rotate, and the rotation of the second rotating ring 6 drives the plurality of annular connecting rods 7 to move, and the movement of the plurality of annular connecting rods 7 drives the plurality of fixed protrusions 8 to move, and the movement of the plurality of fixed protrusions 8 drives the plurality of water retaining blocks 9 to rotate along the fixed points with the second fixed ring 14, and the plurality of water retaining blocks 9 do not cooperate with each other after rotation, so that the water flow has a circular passing area, so that the water flow forms a relatively concentrated water column state when it is sprayed out through the water spray pipe 2, so that the water flow for spraying the water column can be switched;

[0037] After cleaning is completed, the water flow will pass through the filter 18 and fall into the first water tank 19, while the iron filings remaining from processing will remain on the upper end of the filter 18. At this time, the iron filings attached to the inner side wall of the CNC machine tool body 1 will fall onto the surface of the filter 18. The iron filings can be cleaned by pulling out the filter 18, and there is no need to clean them manually, thereby improving cleaning efficiency and reducing cleaning pressure.
