[0022] Example
[0023] Reference Figure 1-2As shown, the utility model discloses a high-pressure nozzle with adjustable spray angle, including a nozzle body 10, a nozzle rod 20 and a clamping nut 30, the nozzle body 10 is provided with a first pipe 101 passing through both ends, a positioning groove 102 is provided at one end of the nozzle body 10, a ball 202 is arranged at one end of the nozzle rod 20, the nozzle rod 20 is provided with a second pipe 201 passing through both ends, and the clamping nut 30 locks the ball 202 in the positioning groove 102. Specifically, the nozzle body 10 has fixed threads at both ends. When installing, the nozzle body 10 is installed on the machine tool through the threads at one end. The clamping nut 30 has a through hole for the nozzle rod 20 to pass through. The nozzle rod 20 passes through the through hole. The ball 202 at one end of the nozzle rod 20 is locked in the positioning groove 102 by the clamping nut 30. The coolant enters the first pipe 101 of the nozzle body 10 and is sprayed out through the second pipe 201 of the nozzle rod 20. First, compared with the traditional riveting fixing method, the utility model adopts an assembly fixing method, which can withstand high-pressure coolant and eliminate safety hazards; on the other hand, the ball 202 can be rotated to adjust the swing angle of the nozzle rod 20 to match different tools, which has good cooling effect and good flushing effect on chips. Furthermore, the edge of the positioning groove 102 is chamfered, and the ball 202 is in surface contact with the edge of the positioning groove 102, so that the rotation of the ball 202 is more lubricated and the adjustment is smoother.
[0024] Reference Figure 1-2 As shown, one end of the second pipe 201 away from the sphere 202 is bent to form a bent jet 203, and the acute angle between the bent jet 203 and the second pipe 201 is 45°. The inclined bent jet 203 allows the sprayed coolant to be further aligned with the contact position between the tool and the workpiece, thereby achieving better chip flushing and cooling effects.
[0025] In addition, the length of the nozzle rod 20 is X, 34 mm ≤ X ≤ 38 mm. In this embodiment, the length of the nozzle rod 20 is 36 mm, which can prevent the nozzle rod 20 from being too long to affect tool processing or too short to cause the coolant to not be sprayed in place.
