[0022] In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present utility model, "a plurality of" means two or more unless otherwise specifically defined.

[0023] The present utility model provides a high-pressure central water supply structure for a turret, as Figure 1 shown, including: a water passage shaft 1, a cavity 2 extending axially is provided in the water passage shaft 1, a water channel 3 extending radially is provided on the outer wall of the water passage shaft 1, the water channel 3 is communicated with the cavity 2, a water distribution plate 4 is rotatably connected to the water passage shaft 1, a plurality of water distribution holes 5 extending radially are provided in the water distribution plate 4, one end of the water distribution hole 5 faces the water passage shaft 1, and a water outlet pipe 6 is installed at the other end of the water distribution hole 5. The water distribution plate 4 is connected to the turret and can rotate together with the turret, and the water outlet pipe 6 is aligned with the cutting tool on the turret so as to cool and lower the temperature of the working cutting tool.

[0024] Working principle and beneficial technical effects of the above technical solution: Water is supplied into the cavity 2. Whenever the cutter head rotates to switch the tool, the water distribution plate 4 also rotates together. The corresponding water distribution holes 5 are communicated with the water channel 3, and the cooling water flows out through the water channel 3, the water distribution holes 5 and the water outlet pipe 6, and sprays the cooling water towards the switched tool. Since the cooling water is supplied from the center of the turret outwards, the cooling water sprays outwards, reducing the cooling water from entering the gap of the turret adapter. The internal structure of the turret is not easy to rust, and the service life of the turret is improved.

[0025] In one embodiment, an annular groove 7 is provided on the inner wall of the water distribution plate 4, and a sealing ring 8 is provided in the annular groove 7. The Gleitring is used as a rotary seal, with high pressure resistance, ensuring the transmission of high-pressure cooling water. The water inlet shaft 1 and the water distribution plate 4 adopt a small clearance seal, which can ensure the minimum leakage while rotating.

[0026] In one embodiment, the right end of the water inlet shaft 1 is connected to one end of the housing 9, the other end of the housing 9 is connected to the first high-pressure joint 10, a seamless steel pipe 11 is provided in the housing 9, a cooling water inlet 12 is provided in the first high-pressure joint 10, one end of the seamless steel pipe 11 is communicated with the cooling water inlet 12, and the other end of the seamless steel pipe 11 is communicated with the cavity 2 through the second high-pressure joint 13. The cooling water inlet 12 is used to connect the water outlet of the high-pressure water pump, and high-pressure cooling water is provided in sequence through the first high-pressure joint 10, the seamless steel pipe 11 and the second high-pressure joint 13. The pressure of the cooling water can reach 100 bar, and it is stable and reliable.

[0027] In one embodiment, as Figures 1 - 3 shown, one end of the water outlet pipe 6 away from the water distribution hole 5 is provided with a conical nozzle 14. The conical nozzle is made of an elastic material. The conical nozzle 14 is provided with a plurality of circumferentially distributed openings 15 along the circumferential direction. An adjusting pipe 16 is threadedly connected to the outer wall of the water outlet pipe 6. A limiting ring 17 is provided on the inner wall of the adjusting pipe 16. The conical nozzle 14 is located within the limiting ring 17. When it is necessary to adjust the size of the nozzle water outlet, rotate the adjusting pipe 16 to drive the limiting ring 17 to move along the axial direction of the conical nozzle 14, so that the conical nozzle is tightened or loosened, thereby changing the size of the nozzle and adjusting the water spray volume of the cooling water to meet the cooling requirements of different cutting states of the tool. The openings 15 are evenly spaced circumferentially around the conical nozzle 14 in four, which is convenient for the processing of the conical nozzle openings, saves processing costs and improves processing efficiency. The outer wall of the adjusting pipe 16 is provided with anti-slip lines, which can increase the friction force and facilitate the rotation and adjustment by personnel.
