[0032] See also Figure 1 An embodiment of the utility model provides a cooling water ring, including: a base 10 and at least two cooling mechanisms 20.

[0033] The base 10 is provided with a mounting hole 11 for the CNC machine tool to pass through; the cooling mechanism 20 includes a plurality of water spray assemblies 21 disposed on the base 10 , and the plurality of water spray assemblies 21 are evenly arranged around the mounting hole 11 .

[0034] The spraying directions of the water spraying components 21 of different cooling mechanisms 20 are oriented toward different preset areas, and different preset areas correspond to different tools.

[0035] The preset area is actually designed according to the shape and size of the tool, and the preset area is usually located at the edge of the contact structure between the tool and the part. For example, the bottom of the tool contacts the part, and the water spray components 21 of the same cooling structure are all facing the bottom edge of the tool. Multiple water spray components 21 of the same cooling structure can cover all angles of the tool as much as possible, so that the sprayed cooling water can cover the position that needs cooling, thereby improving the cooling efficiency.

[0036] For the convenience of explanation, in this embodiment, the cooling water ring includes two cooling mechanisms 20, and the two cooling mechanisms 20 respectively cool the large tool 41 and the small tool 42, and the two preset areas respectively correspond to the bottom edges of the large tool 41 and the small tool 42. Each cooling mechanism 20 includes four water spraying components 21. When the large tool 41 is processed, the cooling mechanism 20 corresponding to the large tool 41 is started, and the four water spraying components 21 spray cooling water in four directions to the position where the large tool 41 contacts the part, while the cooling mechanism 20 corresponding to the small tool 42 is stopped; similarly, when the small tool 42 is processed, the cooling mechanism 20 corresponding to the large tool 41 is stopped, and the cooling mechanism 20 corresponding to the small tool 42 is started, and the four water spraying components 21 spray cooling water in four directions to the position where the small tool 42 contacts the part. By controlling the cooling water spraying separately, precise cooling is achieved, the water spraying flow is concentrated, the cooling efficiency is high, and the cooling effect is good.

The water inlet joint 25 is connected with the lower joint 24 through the water hole 12. The water inlet joint 25 can be connected to the water supply pipeline, and the cooling water passes through the water inlet joint 25, the water hole 12, the lower joint 24 and the regulating head 22 in sequence, and then is sprayed out from the nozzle 23.

[0042] In some optional embodiments, a second ball joint 221 is provided on the adjusting head 22, and the adjusting head 22 is rotatably matched with the spray head 23 via the second ball joint 221.
