The output end of the first motor 11 drives the fixed plate 43 to rotate, and the fixed plate 43 drives the first support rod 37 and the second support rod 38 to rotate in a circle. The first support rod 37 and the second support rod 38 are connected to the first derivative rod 36 and the second derivative rod 39 by limiting rotation, so that the grinding disc 32 can be driven to rotate. The grinding disc 31 on the grinding disc 32 is used to grind the burrs or damage generated at the punching part or around the punching part on the metal pipe 10. According to the metal pipe 10 with different diameters, the second screw 3 can be rotated to grind the burrs or damage generated at the punching part or around the punching part. 4. A third rotating handle 44 is provided on the second screw rod 34, and the second screw rod 34 is driven to rotate by the third rotating handle 44. During the rotation process, the threads at both ends of the second screw rod 34 respectively cooperate with the threads on the inner walls of the first slider 33 and the second slider 35 to drive the first slider 33 and the second slider 35 to slide toward each other, thereby changing the angle between the first support rod 37 and the first derivative rod 36, the second support rod 38 and the second derivative rod 39, thereby controlling the movement of the grinding disc 32, making the grinding disc 32 fit on the wall of the metal pipe 10, and using the grinding sheet 31 on the grinding disc 32 to grind the punching part.

The output end of the third motor 29 drives the drill rod 30 to rotate, and the drill rod 30 is used to drill holes in the metal pipe 10. While drilling, the hydraulic cylinder 28 is controlled to work. The output end of the hydraulic cylinder 28 drives the third motor 29 to move. Both ends of the third motor 29 are respectively provided with second sliding pins 42 slidably connected to the inner wall of the second mounting block 27. The third motor 29 drives the drill rod 30 to move, and the metal pipe 10 is drilled by the self-rotation and drive of the drill rod 30.

[0039] The clamping structure also includes a first screw barrel 14 fixedly connected to the inner wall of the first support plate 2, the first screw barrel 14 has an internal thread that is matched with a first screw rod 13 rotatably connected to the first support plate 2, one end of the first screw rod 13 is fixedly connected to the first fixed plate 9, one end of the transmission rod 21 is rotatably connected to the second fixed plate 17, and the first fixed plate 9 and the second fixed plate 17 are on the same axial line.

[0040] like Figure 1 and 9 As shown, a first rotating handle 12 is provided at one end of the first screw 13, and the first rotating handle 12 is used to drive the first screw 13 to rotate. During the rotation of the first screw 13, the first screw 13 is threadedly engaged with the first screw barrel 14, thereby driving the first screw 13 to move axially along the first screw barrel 14. The first screw 13 drives the first fixed plate 9 to move. Since the position of the second fixed plate 17 at one end of the transmission rod 21 is fixed, the metal pipe 10 is clamped and fixed by the first fixed plate 9 and the second fixed plate 17 by changing the distance between the first fixed plate 9 and the second fixed plate 17.

[0042] like Fig.10 and 11As shown, when the swivel 6 is deflected, the swivel 6 drives the rocker arm 40 to deflect, and the rocker arm 40 can drive the storage box 5 to slide along the slide plate 4 under the limitation of the first sliding pin 41, and the deflection angle of the swivel 6 can affect the axial position of the drill rod 30 and the grinding disc 32 on the metal pipe 10, thereby ensuring that the storage box 5 corresponds to the position of the drill rod 30 and the grinding disc 32, so as to facilitate the collection of powder generated by grinding the grinding disc 32.

[0043] The working process of the present invention is as follows: when the present invention is in use, the first support plate 2 and the second support plate 3 are symmetrically arranged at the two ends of the base 1, and the metal pipe fitting 10 is placed between the first fixed plate 9 and the second fixed plate 17. The first handle 12 drives the first screw 13 to rotate. During the rotation of the first screw 13, it cooperates with the first screw barrel 14 threadedly, thereby driving the first screw 13 to move axially along the first screw barrel 14. The first screw 13 drives the first fixed plate 9 to move. Since the position of the second fixed plate 17 at one end of the transmission rod 21 is fixed, the metal pipe fitting 10 is clamped and fixed by using the first fixed plate 9 and the second fixed plate 17 by changing the distance between the first fixed plate 9 and the second fixed plate 17.

[0044] The second rotating handle 16 drives the worm 20 to rotate, and the worm 20 drives the worm wheel 19 to rotate. The worm wheel 19 drives the swivel 6 to deflect through the rotating column 18. When the transmission rod 21 drives the sliding fixed plate 8 to rotate, it drives the first sliding column 24 and the second sliding column 25 to rotate circumferentially respectively, and the first sliding column 24 and the second sliding column 25 can be limited by the deflection angle of the swivel 6 to adjust the position along the axial direction of the metal pipe fitting 10, which effectively increases the processing surface.

The first sliding column 24 and the second sliding column 25 respectively drive the drill rod 30 and the grinding disc 32 to adjust the position along the axial direction of the metal pipe fitting 10, and the position of the drill rod 30 and the grinding disc 32 along the axial direction of the metal pipe fitting 10 is limited by the deflection angle of the swivel 6.

[0045] The output end of the first motor 11 drives the fixed plate 43 to rotate, and the fixed plate 43 drives the first support rod 37 and the second support rod 38 to rotate in a circle. The first support rod 37 and the second support rod 38 are connected to the first deflector rod 36 and the second deflector rod 39 by limiting rotation, so that the grinding disc 32 can be driven to rotate, and the grinding disc 31 on the grinding disc 32 is used to grind the burrs or damage generated at the punching part or around the punching part on the metal pipe 10. According to the metal pipe 10 with different diameters, the second screw 34 can be rotated, and the second screw 34 is provided with a third rotating The handle 44 drives the second screw rod 34 to rotate through the third rotating handle 44. During the rotation process, the threads at both ends of the second screw rod 34 cooperate with the inner wall threads of the first slider 33 and the second slider 35 respectively to drive the first slider 33 and the second slider 35 to slide toward each other, thereby changing the angle between the first support rod 37 and the first derivative rod 36, the second support rod 38 and the second derivative rod 39 at the rotating shaft rod, thereby controlling the movement of the grinding disc 32, fitting the grinding disc 32 on the wall of the metal pipe 10, and using the grinding disc 31 on the grinding disc 32 to grind the punching part.

[0046] The third motor 29 is working, and the output end of the third motor 29 drives the drill rod 30 to rotate, and the metal pipe 10 is drilled by the drill rod 30. While drilling, the hydraulic cylinder 28 is controlled to work, and the output end of the hydraulic cylinder 28 drives the third motor 29 to move. The two ends of the third motor 29 are respectively provided with a second sliding pin 42 which is slidably connected to the inner wall of the second mounting block 27. The third motor 29 drives the drill rod 30 to move, and the metal pipe 10 is drilled by the self-rotation and drive of the drill rod 30. The circumferential rotation trajectories of the drill rod 30 and the grinding disc 32 are the same, so that after drilling the required part of the metal pipe 10, the grinding disc 32 is used to grind the burrs or damage generated at the drilling part or around the drilling, without the need for repositioning, which effectively saves time and improves work efficiency.

[0047] When the swivel 6 is deflected, the swivel 6 drives the rocker arm 40 to deflect, and the rocker arm 40 can drive the storage box 5 to slide along the slide plate 4 under the limitation of the first sliding pin 41, and the deflection angle of the swivel 6 can affect the axial position of the drill rod 30 and the grinding disc 32 on the metal pipe 10, thereby ensuring that the storage box 5 corresponds to the position of the drill rod 30 and the grinding disc 32, so as to facilitate the collection of powder generated by grinding.
