[0022] The embodiment of the present application discloses a cutting fluid spraying mechanism with adjustable angle.

[0023] The angle adjustment mechanism includes a worm 16 which is rotatably connected to the outer wall of the middle section of the top of the lower connecting member 7 through a shaft seat 15. A servo motor 17 is fixedly installed on the outer wall of one side of the shaft seat 15. The end of the output shaft of the servo motor 17 is fixedly connected to one end of the worm 16. A worm gear 18 is fixedly connected to the outer wall of the middle section of the rotating shaft 8, and the worm gear 18 is meshed with the worm 16.

[0024] A stepper motor 13 is fixedly mounted on the top inner wall of the bearing seat 4 , and a gear 14 is fixedly connected to the end of the output shaft of the stepper motor 13 , and the gear 14 is meshed with the inner gear ring 6 .

[0025] The clamping mechanism includes a plurality of limit frames 19 fixedly connected to the bottom outer wall of the upper connecting member 9 , and the outer walls of every two adjacent limit frames 19 are slidably connected with a fixing member 20 , and the top inner wall of the fixing member 20 fits with the top outer wall of the base 10 .

[0026] A plurality of positioning holes 12 are formed on the outer wall of the base 10 , and two positioning blocks 24 are fixedly connected to the top inner wall of the fixing member 20 . The positioning blocks 24 are adapted to be plugged into the positioning holes 12 .

[0027] The clamping mechanism also includes two threaded rods 21 rotatably connected to the bottom outer wall of the upper connecting member 9. The bottom outer walls of the two fixing members 20 are provided with nut rings 22, which are meshed with the threaded rods 21. The bottom end of the threaded rod 21 is fixedly connected to a knob 23.

[0028] The outer wall of the fixing base 1 is provided with a plurality of fixing holes 2 , which are evenly distributed at the four corner edges of the fixing base 1 .

[0029] The implementation principle of the angle-adjustable cutting fluid spraying mechanism of the embodiment of the present application is as follows: when in use, the fixing base 1 is fixed to a suitable position of the machine tool through the multiple fixing holes 2. When the spraying angle of the nozzle assembly 11 needs to be adjusted, the stepping motor 13 is first started. The output shaft of the stepping motor 13 drives the gear 14 to rotate. At this time, the gear 14 drives the inner ring gear 6 meshing with it to rotate. The inner ring gear 6 rotates in the bearing seat 4 through the shaft cylinder 5. The inner ring gear 6 drives the lower connecting member 7 and the nozzle assembly 11 above it to rotate horizontally, thereby adjusting the horizontal angle of the nozzle assembly 11;

[0030] Then the servo motor 17 is started, and the output shaft of the servo motor 17 drives the worm 16 to rotate in the shaft seat 15, and then drives the worm wheel 18 to rotate through the engagement of the worm 16 and the worm wheel 18. At this time, the worm wheel 18 will drive the rotating shaft 8 to rotate at the top of the lower connecting member 7, and the rotating shaft 8 will drive the upper connecting member 9 to rotate around the top of the lower connecting member 7, thereby adjusting the pitch angle of the nozzle assembly 11 above the upper connecting member 9, and realizing the angle adjustment of the nozzle assembly 11 in the horizontal or vertical direction. During the adjustment process, the spray range of the cutting fluid can be observed to ensure that it covers the entire processing area;

[0031] Secondly, the knob 23 can be turned through the clamping mechanism so that the knob 23 drives the threaded rod 21 to rotate on the bottom outer wall of the upper connecting member 9. At this time, the threaded rod 21 rotates on the inner surface of the nut ring 22, driving the nut ring 22 to move up and down on the outer wall of the knob 23. The nut ring 22 drives the fixing member 20 to move up and down on the outer wall of the limit frame 19. When the fixing member 20 moves up, it will drive the positioning block 24 out of the positioning hole 12, thereby releasing the lock on the base 10. Then the base 10 can be pulled out from between the two fixing members 20 and the upper connecting member 9, and the fixing member 20 can be The nozzle assembly 11 can be disassembled and replaced to facilitate the replacement of nozzles of different diameters or shapes, thereby expanding the scope of application of the device. When the replacement is completed and needs to be installed, the base 10 is re-placed between the two fixing parts 20 and the upper connecting part 9, and the positioning hole 12 on the outer wall of the base 10 is aligned with the positioning block 24. Similarly, the knob 23 is turned to move the fixing part 20 downward. When the fixing part 20 moves downward, it contacts the base 10 and clamps the base 10. At the same time, the positioning block 24 is re-inserted into the positioning hole 12 to position the base 10 to prevent displacement and improve the firmness of the installation.
