[0002] With the development of industrial production, the requirements for the internal quality of pipelines are getting higher and higher. Seamless steel pipes, as an important pipe material, are widely used in the fields of petroleum, chemical industry, electric power, etc. However, due to the production process, the inner wall of seamless steel pipes often has problems such as unevenness and burrs, which not only affect the fluid transportation efficiency, but also may cause safety hazards.

[0003] In the prior art, there are usually manual grinding, turntable grinders and pneumatic grinding heads. The turntable grinder grinds the inner wall of the pipe with a rotating grinding wheel and has a high working efficiency. However, this equipment can usually only be used for pipes with smaller diameters, and its application to large seamless steel pipes is limited. The pneumatic grinding head can be inserted into the interior of a seamless steel pipe with a larger diameter for grinding, and vibration will be generated during the working process. Especially when running at high speed, the vibration will easily cause uneven pressure distribution of the grinding head, resulting in unstable grinding force and affecting the polishing effect.

[0034] Please refer to Figure 1 , Figure 6 The distance adjustment mechanism 3 includes a support plate 1 31 and a support plate 2 32 fixedly connected to the top surface of the support frame 1. The top surfaces of the support plate 1 31 and the support plate 2 32 are both provided with a slide groove 1 33. A screw rod 1 34 is rotatably arranged in the slide groove 1 33 on the top surface of the support plate 1 31. Two connecting blocks 35 are fixedly connected to both ends of the bottom surfaces of the two mounting plates 21. The two connecting blocks 35 are respectively arranged in the slide groove 1 33 on the top surfaces of the support plate 1 31 and the support plate 2 32, and the two connecting blocks 35 are slidably connected to the slide groove 1 33. The screw rod A 34 passes through the adjacent connecting block 35 and is threadedly connected thereto. The screw rod 34 is a bidirectional screw rod. The screw rod 34 is fixedly connected to a bevel gear 14. The top surface of the support plate 31 is rotatably connected to a rotating shaft 16. A rotating assembly 17 is provided at the top of the rotating shaft 16. The rotating assembly 17 includes a rotating plate fixedly connected to the top of the rotating shaft 16, and a rotating handle is fixedly connected to the top surface of the rotating plate. The outer periphery of the rotating handle is provided with anti-slip grooves. A bevel gear 2 15 is fixedly connected to the bottom end of the rotating shaft 16, and the bevel gear 2 15 is meshingly connected to the bevel gear 14.

[0035] Specifically, rotating the handle drives the rotating plate and the rotating shaft 16 to rotate, making it easier to rotate the screw rod 34 and easier to adjust the spacing of the mounting plate 21. The rotating shaft 16 rotates, driving the bevel gear 14 and the bevel gear 2 15 to rotate, thereby rotating the screw rod 34. Since the screw rod 34 is a bidirectional screw rod, it can drive the two connecting blocks 35 to move closer to or away from each other, thereby making the mounting plates 21 closer to or away from each other. The mounting plates 21 are closer to each other to adapt to seamless steel pipes with smaller diameters, and vice versa, they are adapted to seamless steel pipes with larger diameters, thereby solving the problem of poor adaptability to seamless steel pipes of different specifications.

[0036] Please refer to Figure 4 The limiting mechanism 4 includes a mounting frame 41 fixedly connected to the top surface of the support frame 1, a cylinder 42 is fixedly connected to the top surface of the mounting frame 41, and the output end of the cylinder 42 passes through the mounting frame 41 and is fixedly connected to a mounting seat 43, and a turntable 44 is rotatably connected to the side wall of the mounting seat 43.

[0037] Specifically, the mounting seat 43 is driven to rise and fall by the cylinder 42, so that the turntable 44 contacts the top surface of the seamless steel pipe. The turntable 44 can rotate, which can limit the seamless steel pipe and prevent the seamless steel pipe from bouncing up, which is beneficial to the stability of the seamless steel pipe during rotation.

[0038] Please refer to Figure 1 , Figure 2 The moving mechanism 5 includes slide rails 51 fixedly connected to both sides of the support frame 1, wherein a screw rod 2 53 is rotatably arranged in one of the slide rails 51, and a motor 1 52 is also installed on the side wall of the slide rail 51, and the output end of the motor 1 52 is fixedly connected to the screw rod 2 53, and a vertical rod 54 is slidably connected in both slide rails 51, and the screw rod 2 53 penetrates the vertical rod 54 and is threadedly connected thereto, and the adjustment mechanism 6 is arranged between the two vertical rods 54, and the lateral adjustment component 61 includes a moving platform 611 fixedly connected between the two vertical rods 54, and a motor 2 612 is fixedly connected to the side wall of the moving platform 611, and the moving platform 611 A second slide groove 613 is provided inside, a screw rod 3 614 is rotatably provided inside the second slide groove 613, and the screw rod 3 614 is fixedly connected to the output end of the second motor 612, a mounting block 615 is threadedly connected to the screw rod 3 614, and a longitudinal adjustment component 62 is provided on the mounting block 615. The longitudinal adjustment component 62 includes a fourth slide groove 621 provided on the side of the mounting block 615, a second cylinder 622 is fixedly connected to the top surface of the mounting block 615, a lifting block 623 is fixedly connected to the output end of the second cylinder 622, the lifting block 623 is slidably connected to the fourth slide groove 621, and the connecting rod 7 is fixedly connected to the lifting block 623.

[0039] Specifically, when the grinding head 8 needs to be moved, the driving motor 1 52 drives the screw rod 2 53 to rotate, thereby driving the vertical rod 54 to move, and the adjusting mechanism 6 and the grinding head 8 can move with the movement of the vertical rod 54. When the grinding head 8 needs to be adjusted to move laterally, the driving motor 2 612 drives the screw rod 3 614 to rotate, so that the mounting block 615 moves in the slide groove 2 613. The mounting block 615 can drive the longitudinal adjustment component 62 and the grinding head 8 to move, so that the grinding head 8 can be adjusted to move laterally. When the grinding head 8 needs to be adjusted to move longitudinally, the driving cylinder 2 622 drives the lifting block 623 to move in the slide groove 4 621, so that the grinding head 8 can be adjusted to move longitudinally.

[0040] How it works In the initial state, the receiving plate 10 is located at the center line of the top surface of the support frame 1. The spacing between the two mounting plates 21 is adjusted according to the seamless steel pipe. The rotating handle drives the rotating plate and the rotating shaft 16 to rotate, so that the screw rod 34 can rotate more conveniently, and the spacing adjustment of the mounting plate 21 is more convenient. The rotating shaft 16 rotates, driving the bevel gear 14 and the bevel gear 2 15 to rotate, thereby rotating the screw rod 34. Since the screw rod 34 is a bidirectional screw rod, it can drive the two connecting blocks 35 to move closer to or away from each other, so that the mounting plates 21 can move closer to or away from each other. The mounting plates 21 move closer to each other to adapt to seamless steel pipes with smaller diameters, and vice versa to adapt to seamless steel pipes with larger diameters, which solves the problem of poor adaptability to seamless steel pipes of different specifications. The mounting seat 43 is driven to rise and fall by the cylinder 1 42, so that the turntable 44 contacts the top surface of the seamless steel pipe. The turntable 44 can rotate, which can limit the seamless steel pipe and prevent the seamless steel pipe from bouncing up, which is beneficial to the stability of the seamless steel pipe during rotation. Next, move the receiving plate 10 so that it is not located at the center line of the top surface of the support frame 1, and then place the seamless steel pipe on the two rollers 23, use a caliper to measure the height between the center of the seamless steel pipe and the top surface of the support frame 1, adjust the telescopic rod 11, there is a height mark on the receiving plate 10, make the center point of the receiving plate 10 level with the center of the seamless steel pipe, and then replace the grinding head 8 according to the size of the seamless steel pipe; The stepper motor in the driving support frame 1 drives the driving gear and the driven gear to rotate, which can drive the two rollers 23 to rotate in the same direction. When the two rollers 23 rotate in the same direction, the seamless steel pipes thereon can continue to rotate in the opposite direction. When it is necessary to move the grinding head 8, the driving motor 1 52 drives the screw 2 53 to rotate, thereby driving the vertical rod 54 to move. The adjusting mechanism 6 and the grinding head 8 can move with the movement of the vertical rod 54. During the grinding process, if the seamless steel pipe rotates, the vibration of the grinding head 8 will be slightly offset, and the light irradiated by the infrared emitting lamp 9 will move in the projection of the receiving plate 10, and the deviation distance and deviation direction can be intuitively seen. The position of the grinding head 8 can be adjusted in time according to the movement of the projection through the adjusting mechanism 6, and the position of the grinding head 8 can be dynamically adjusted to ensure that the grinding force is constant, thereby solving the vibration of the seamless steel pipe. The vibration generated during movement causes the grinding head 8 to shift, resulting in uneven pressure distribution of the grinding head 8 and unstable grinding force. When the grinding head 8 needs to be adjusted for lateral movement, the driving motor 2 612 drives the screw rod 3 614 to rotate, so that the mounting block 615 moves in the slide groove 2 613. The mounting block 615 can drive the longitudinal adjustment component 62 and the grinding head 8 to move, thereby enabling the grinding head 8 to be adjusted for lateral movement. When the grinding head 8 needs to be adjusted for longitudinal movement, the driving cylinder 2 622 drives the lifting block 623 to move in the slide groove 4 621, thereby enabling the grinding head 8 to be adjusted for longitudinal movement.
