Technical Field
[0001] This utility model belongs to the field of welded pipe processing technology, specifically relating to a clamping fixture for high-frequency welded pipe processing. Background Technology
[0002] technology High-frequency welded pipe is a straight seam resistance welded steel pipe made from hot-rolled coil as raw material. After being formed by a forming machine, the edge of the pipe blank is melted by the skin effect and proximity effect of high-frequency current, and then pressure welded by extrusion rollers. The product type belongs to steel pipe. The welding process of high-frequency resistance welded steel pipe is different from that of ordinary welded pipe. The weld is formed by melting the base material of the steel strip body. The mechanical strength is better than that of ordinary welded pipe. When performing various processing on the welded pipe, it is often necessary to fix the welded pipe with clamping fixtures.
[0003] Existing clamping fixtures lack auxiliary structures, requiring manual lifting of both sides of the welded pipe before clamping it using the clamping structures on both sides. This is inconvenient to use. Furthermore, existing clamping fixtures cannot flip the welded pipe, often requiring manual flipping, which is time-consuming and labor-intensive. Therefore, we propose a clamping fixture for high-frequency welded pipe processing. Utility Model Content

In addition, the existing clamping fixtures cannot flip the welded pipe, and it is often necessary to manually flip the welded pipe, which is time-consuming and laborious.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0017] Please see Figure 1-5 One embodiment provided by this utility model: A clamping fixture for high-frequency welded pipe processing includes a worktable 1. A first slide groove 11 is formed on the top of the worktable 1, and second slide grooves 12 are formed on both sides of the top of the worktable 1. An auxiliary structure 2 is provided inside the first slide groove 11, including a handle 21. A threaded rod 22 is fixedly connected to the surface of the handle 21. Two sets of limiting rods 23 are fixedly connected inside the first slide groove 11. Two sets of sliders 24 are symmetrically slidably connected to the surfaces of the threaded rods 22 and the limiting rods 23. An auxiliary roller 25 is mounted on the top of each set of sliders 24. A moving structure 3 is provided on both sides of the top of the worktable 1, and the moving structure 3 includes a motor 3. 1. A lead screw 32 is fixedly connected to the output end of motor 31. A linear slide rail 33 is fixedly connected inside the slide groove 12. A sliding plate 34 is slidably connected to the surfaces of the lead screw 32 and the linear slide rail 33. A mounting plate 4 is fixedly connected to the top of the sliding plate 34. Two sets of fixing brackets 41 are fixedly connected to the top of the mounting plate 4. A top plate 42 is fixedly connected to the top of the two sets of fixing brackets 41. An adjustment structure 5 is provided on the top of the mounting plate 4. The adjustment structure 5 includes a motor 51. A lead screw 52 is fixedly connected to the output end of motor 51. A limit rod 53 is fixedly connected to the top of the mounting plate 4. The two sets of fixing brackets 41... The surfaces of the two auxiliary rollers 25 are fixedly connected to linear guide rails 54. Sliding blocks 55 are slidably connected to the surfaces of the lead screw 52 and the limit rod 53. A motor 56 is fixedly connected to one side of the sliding block 55. A rotating disk 57 is fixedly connected to the output end of the motor 56. An anti-slip pad 58 is fixedly connected to the surface of the rotating disk 57. An auxiliary structure 2 is provided. Before clamping the welded pipe, rotating the handle 21 drives the threaded rod 22 to rotate. The two sets of opposite threads on the surface of the threaded rod 22 drive the two sets of sliders 24 to slide within the groove 11, thereby changing the distance between the two sets of auxiliary rollers 25. The welded pipe is then placed on the adjusted two sets of auxiliary rollers 25. The surface of plate 5 is used to clamp the end of the welded pipe. During clamping, there is no need for manual lifting of the welded pipe. At the same time, the spacing of the auxiliary rollers 25 can be adjusted according to the diameter of the welded pipe, which improves adaptability. An adjustment structure 5 is set up. The second motor 51 drives the second lead screw 52 to rotate, so that the sliding block 55 moves up and down along the second lead screw 52. The height of the rotating plate 57 can be adjusted according to the different diameters of the welded pipe, so that the center of the rotating plate 57 is close to the center of the welded pipe during clamping, which increases the stability of rotation during clamping. The third motor 56 can drive the rotating plate 57 to rotate, realizing the automatic flipping of the welded pipe without the need for manual flipping, saving time and effort.
[0018] Furthermore, motor 1 (31), motor 2 (51), and motor 3 (56) are all electrically connected to an external power source, which supplies power to motor 1 (31), motor 2 (51), and motor 3 (56) and controls them uniformly.
[0019] Furthermore, the surface of the threaded rod 22 is provided with two sets of opposite threads, and two sets of sliders 24 are respectively matched with the two sets of threads. The two sets of sliders 24 are slidably connected in the slide groove 11. The surface of the sliders 24 is provided with a circular groove that matches the limiting rod 23. Rotating the handle 21 drives the threaded rod 22 to rotate. The two sets of opposite threads on the surface of the threaded rod 22 drive the two sets of sliders 24 to slide in the slide groove 11, thereby changing the distance between the two sets of auxiliary rollers 25. The movement of the sliders 24 is limited by the cooperation of the limiting rod 23 and the circular groove to prevent rotation.
[0020] Furthermore, the surface of the sliding plate 34 is provided with a threaded groove that matches the lead screw 32, and the two sides of the sliding plate 34 are provided with grooves that match the linear slide rail 33. The motor 31 drives the lead screw 32 to rotate, which cooperates with the threaded groove to adjust the position of the sliding plate 34. The linear slide rail 33 and the grooves limit the sliding plate 34, thereby increasing the stability of the movement of the sliding plate 34.
[0021] Furthermore, the surface of the sliding block 55 is provided with a threaded groove that matches the lead screw 52, and the surface of the sliding block 55 is provided with a circular groove that matches the limiting rod 53. The two sides of the sliding block 55 are provided with grooves that match the linear slide rail 54. The motor 51 drives the lead screw 52 to rotate, which cooperates with the threaded groove to adjust the position of the sliding block 55. The movement of the sliding block 55 is limited by the cooperation of the limiting rod 53 and the circular groove to prevent rotation. The linear slide rail 54 and the groove increase the stability of the sliding block 55 when it moves.
[0022] Furthermore, the output end of motor 3 56 passes through sliding block 55 and is fixedly connected to rotating disk 57. Rotating disk 57 is a rotatable structure on sliding block 55. Motor 3 56 can drive rotating disk 57 to rotate, thereby flipping the clamped welded pipe.
[0023] Furthermore, the anti-slip pad 58 is made of rubber, which increases the friction between the pad and the welded pipe during clamping, while also protecting the surface of the welded pipe.
[0024] Working principle: Before clamping, rotating the handle 21 drives the threaded rod 22 to rotate. The two sets of opposite threads on the surface of the threaded rod 22 drive the two sets of sliders 24 to slide in the groove 11, thereby changing the distance between the two sets of auxiliary rollers 25. The welded pipe is placed on the surface of the two sets of auxiliary rollers 25 after adjustment. The motor 51 drives the lead screw 52 to rotate, causing the sliding block 55 to move up and down along the lead screw 52. The height of the center of the rotating disk 57 is adjusted to be close to the center of the welded pipe, increasing the stability of rotation during clamping. The motor 31 drives the lead screw 32 to rotate, which, in conjunction with the threaded groove, adjusts the position of the sliding plate 34 to clamp the welded pipe from the end. The motor 56 drives the rotating disk 57 to rotate, realizing the automatic flipping of the welded pipe.
