By removing the excess height and uneven parts of the weld, the inner and outer walls of the steel pipe are smoother and more uniform, thereby improving the quality of the steel pipe; unpolished welds may have sharp edges or protrusions, which may cause stress concentration during use, increasing the risk of breakage or leakage of the steel pipe. By grinding the weld, these safety hazards can be eliminated and the reliability of the steel pipe can be improved. With the continuous development of industrial automation, steel pipe production is also facing the challenges of improving production efficiency and reducing labor costs. The emergence of steel pipe weld grinding device just meets this demand. It can automatically and efficiently complete the grinding of welds, which not only improves production efficiency, but also reduces dependence on manual labor and reduces labor costs.

[0017] like Figure 1 and Figure 3As shown, a steel pipe weld grinding device, the steel pipe weld grinding device specifically includes a grinding workbench 1, a moving component, a grinding component and a limiting component are arranged on the grinding workbench, the moving component includes a moving platform 2, a rotating screw rod 3, a screw block 4, a sliding rail 5 and a driving motor 6, the moving platform 2 is slidingly arranged on the sliding rail 5, one end of the rotating screw rod 3 is rotatably connected to the driving motor 6, the rotating screw rod 3 is rotatably connected to the internal thread of the screw block 4 under the moving platform 2 through a thread, and the other end of the rotating screw rod 3 is rotatably connected to the bearing seat 7, the grinding component includes a first grinding head 8, a second grinding head 9, a first rotating rod 10, a second rotating rod 11, a grinding motor 12, a first connecting frame 13 and a second connecting frame 14, the first connecting frame 13 is rotatably installed with the first rotating rod 10, and the first rotating rod 11 is rotatably connected to the driving motor 6. The first grinding head 8 is sleeved on the movable rod 10, the second rotating rod 11 is rotatably installed in the second connecting frame 14, the second grinding head 9 is sleeved on the second rotating rod 11, the first rotating rod 10 and the second rotating rod 11 are connected to the grinding motor 12 on the outside, the limiting components include a pipe clamp holding platform 15, a hoop 16, a positioning clamp 17 and a pipe clamp cover plate 18, the pipe clamp holding platform 15 is arranged below the hoop 16, the positioning clamp 17 is arranged on the outer wall of the hoop 16, the pipe clamp cover plate 18 is arranged on the positioning clamp 17, one end of the positioning clamp 17 is connected to the pipe clamp holding platform 15, and a debris collection tank 19 is installed at the bottom end of the grinding workbench 1. In specific implementation, the grinding workbench 1 provides a stable working environment, which can support and fix all grinding and moving components to ensure the stability of the grinding process. The movable platform 2 on the movable assembly slides on the sliding rail 5 to realize flexible adjustment of the grinding position to meet the grinding requirements of steel pipes of different lengths. The rotating screw 3 is driven by the driving motor 6 to realize the linear motion of the screw block 4, thereby promoting the sliding of the movable platform 2. It has the advantages of simple structure and smooth movement. The screw block 4 is connected to the rotating screw 3 by a thread, which can convert the rotational motion of the rotating screw into linear motion, thereby driving the movable platform 2 to slide. The sliding rail 5 provides guidance and support for the movable platform 2 to ensure the stability of the movable platform 2 during movement. The driving motor 6 provides power to drive the rotating screw 3 to rotate, thereby controlling the moving speed and position of the movable platform 2. The first rotating rod 10 and the second rotating rod 11 are respectively connected to the first grinding head 8 and the second grinding head 9. The grinding head is rotated by the driving of the grinding motor 12. The grinding motor 12 provides power to drive the first rotating rod 10 and the second rotating rod 11 to rotate, so as to realize the grinding function of the grinding head. The first connecting frame 13 and the second connecting frame 14 respectively fix the first rotating rod 10 and the second rotating rod 11 to ensure the stability of the grinding head during the grinding process. The pipe clamp holding table 15 on the limiting component provides a stable supporting surface for placing the steel pipe to be ground. There are multiple hoops 16, and the spacing gradually increases, which can adapt to steel pipes of different diameters and improve the application range of the device. An arc top is arranged in the positioning clamp 17, which fits tightly with the hoop 16, can firmly fix the steel pipe and prevent the movement of the steel pipe during the grinding process. The pipe clamp cover plate 18 is arranged on the positioning clamp 17.Cooperating with the pipe clamping table 15, a complete clamping structure is formed to ensure the stability of the steel pipe. The debris collection groove 19 can effectively collect the debris generated during the grinding process, keep the working environment clean and tidy, and prevent the debris from interfering with the grinding process.

[0018] like Figure 2 As shown, based on the above method, there are multiple hoops 16, and the distance between the multiple hoops 16 gradually increases in the direction away from the drive motor 6. During implementation, since the distance between the hoops gradually increases, this design can well adapt to steel pipes of different diameters. Since there are multiple hoops and the spacing is adjustable, they can fit the outer wall of the steel pipe more closely and provide stronger clamping force.

[0019] like Figure 2 As shown, on the basis of the above method, an arc-shaped top is further provided in the positioning clamp 17, and the positioning clamp 17 is closely fitted with the hoop 16. In implementation, since the arc-shaped top is provided in the positioning clamp 17, this shape matches the arc surface of the steel pipe, and can provide a more uniform and tighter clamping force. The design of the arc-shaped top makes the contact surface of the positioning clamp and the steel pipe more closely fitted, reducing the damage to the steel pipe surface caused by improper clamping.

[0020] like Figure 3 As shown, on the basis of the above method, a fixed block 20 is further provided at the connection between the rotating screw 3 and the driving motor 6. The fixed block 20 is provided at the connection between the rotating screw 3 and the driving motor 6, which enhances the stability of the connection and prevents loosening due to vibration during the grinding process.

[0021] like Figure 1 As shown, on the basis of the above method, the first grinding head 8 and the second grinding head 9 are respectively a coarse sand grinding head and a fine sand grinding head. During implementation, the coarse sand grinding head can quickly remove the rough parts and large uneven areas on the surface of the steel pipe weld, providing a good foundation for subsequent fine grinding. The fine sand grinding head can further refine the grinding effect on the basis of coarse grinding, making the weld surface smoother, thereby improving the work efficiency of the entire grinding process. The combined use of coarse sand and fine sand can ensure that the weld surface can remove defects and maintain smoothness during the grinding process. The coarse sand grinding head removes large particles of impurities, and the fine sand grinding head further eliminates subtle unevenness, thereby ensuring the improvement of grinding quality.

[0022] like Figure 1 As shown, on the basis of the above method, an adjusting movable handle 21 is further provided under the driving motor 6, and the adjusting movable handle 21 pushes the driving motor 6 to move horizontally left and right on the grinding workbench 1. The adjusting movable handle 21 facilitates the operator to adjust the position of the driving motor 6, thereby adjusting the distance between the grinding head and the steel pipe to meet different grinding requirements.

[0023] In the specific working process of the new steel pipe weld grinding device, first, the operator selects a suitable hoop 16 according to the diameter of the steel pipe to be ground, and places the steel pipe on the pipe clamp holding platform 15. Subsequently, the operator puts the hoop 16 on the steel pipe and adjusts the position of the hoop as needed to ensure that the steel pipe is firmly clamped. At this time, the arc top in the positioning clamp 17 fits tightly with the outer wall of the steel pipe, providing additional fixing force to prevent the steel pipe from moving during the grinding process. Next, the operator adjusts the position of the drive motor 6 by adjusting the moving handle 21, thereby controlling the position of the rotating screw 3 and the screw block 4, and then determining the specific position of the moving platform 2 on the sliding rail 5. This step ensures that the grinding head can be accurately positioned at the steel pipe weld. Then, the operator starts the drive motor 6, and the drive motor 6 drives the rotating screw 3 to rotate. Since the screw block 4 is connected to the rotating screw 3 by threads, the rotational motion of the rotating screw 3 is converted into the linear motion of the screw block 4, thereby pushing the moving platform 2 to slide on the sliding rail 5. In this way, the grinding assembly (including the first grinding head 8 and the second grinding head 9) is moved to a suitable position and is ready for grinding. When the moving platform 2 reaches the predetermined position, the operator starts the grinding motor 12. The grinding motor 12 drives the first rotating rod 10 and the second rotating rod 11 to rotate, thereby driving the first grinding head 8 and the second grinding head 9 to rotate. The two grinding heads begin to grind the steel pipe weld. The coarse sand grinding head first removes the rough parts and uneven areas on the weld surface, and then the fine sand grinding head further refines the grinding effect to make the weld surface smooth. During the grinding process, the generated debris will be effectively collected by the debris collection tank 19 to keep the working environment clean. The operator can adjust the position, angle or speed of the grinding head at any time by observing the grinding effect to meet different grinding requirements. Finally, when the grinding is completed, the operator turns off the drive motor 6 and the grinding motor 12, removes the polished steel pipe, and then prepares for the next round of grinding. During the whole process, the new steel pipe weld grinding device realizes efficient and precise grinding of the steel pipe weld through its stable structure, flexible moving components and efficient grinding components, thereby improving work efficiency and grinding quality.
