Starting the motor 3 to drive the transmission rod 4 to rotate, the grinding head 6 will chamfer the hydraulic pipe joint. At the same time, the first bevel gear 5 will drive the second bevel gear 8 to rotate, and then the rotating rod 7 drives the cam 9 to push the sliding rod 12 to slide. The elastic force of the first spring 14 will cause the sliding rod 12 to reset. In this way, the piston 13 will reciprocate, causing the inside of the air cylinder 11 to continuously intake air and then discharge it through the outlet pipe 15, blowing air at the chamfering position of the hydraulic pipe joint to blow off metal debris and avoid affecting the chamfering effect.

[0023] Referring to Figures 1 - 3, the switching component includes an electric push rod 18. One end of the electric push rod 18 is installed on the outer side of the movable frame 17. The output end of the electric push rod 18 is fixedly connected with an assembly block 19. An ear plate 20 is fixedly connected to the outer side of the assembly block 19. A clamping hole 21 is opened inside the ear plate 20. A clamping block 22 is slidably connected to the outer side of the assembly block 19. A fixing block 23 is fixedly connected to the outer side of the clamping block 22. A cavity is opened inside the fixing block 23. A locking rod 24 is slidably connected at the through hole of the cavity. A second spring 26 is sleeved on the outer side of the locking rod 24. A sliding plate 25 is fixedly connected to the outer side of the locking rod 24. One end of the second spring 26 is fixedly connected to the inner wall of the cavity, and the other end of the second spring 26 is fixedly connected to the outer side of the sliding plate 25. One end of the locking rod 24 is clamped inside the clamping hole 21. A pull ring is arranged at one end of the locking rod 24.

Then start the motor 3 to drive the transmission rod 4 to rotate, so that the grinding head 6 rotates to chamfer the hydraulic pipe joint. At this time, the first bevel gear 5 will drive the second bevel gear 8 to rotate, so that the rotating rod 7 drives the cam 9 to rotate, and then pushes the sliding rod 12 to slide. The elastic force of the first spring 14 will make the sliding rod 12 reset. In this way, the piston 13 will reciprocate, and the inside of the air cylinder 11 will continuously intake air and then discharge it through the air outlet pipe 15, blowing air at the chamfered position of the hydraulic pipe joint to blow off the metal chips and avoid affecting the chamfering effect. In addition, a pull ring is arranged at one end of the locking rod 24. Pulling the pull ring can pull the locking rod 24 out of the clamping hole 21. In this way, the clamping block 22 can be easily removed from the outside of the assembly block 19, and different clamping blocks 22 can be replaced to adapt to other models of hydraulic pipe joints.
