Description

Technical Field

[0001] This invention relates to the field of pipe welding technology, and more specifically, to an automated pipe welding device. Background Technology

[0002] Circular pipe fittings are used in various facilities such as industrial production, construction, and transportation. Considering factors such as economy, flexibility, maintainability, and technical feasibility in engineering practice, circular pipe fittings need to be spliced ​​together through welding.

[0003] During the pipe welding process, the specific mechanical constraint structure of the welding fixture is used to position and clamp the pipe, so as to achieve precise positioning and stable clamping of the pipe. This ensures that the pipe is always in the preset position without displacement deviation during the welding process, thereby effectively controlling the pipe welding deformation and meeting the dimensional and positional tolerance requirements of pipe welding.

[0004] In existing technologies, a seamless, high-strength connection is achieved by heating two or more pipe materials to their melting point and joining them together. Heat fuses the two pipe materials into a single unit. Since pipes are typically circular, they need to be clamped and fixed before welding can be performed efficiently. However, during the welding process, the high-temperature heat source causes volume changes in the weld joint material, resulting in deformation. This deformation leads to stress concentration, making the weld joint prone to stress concentration phenomena. Furthermore, when the weld joint is subjected to external loads, the stress concentration area bears even greater stress, thus reducing the strength and durability of the weld joint. How to invent an automated pipe welding device to solve these problems has become an urgent issue for those skilled in the art. Summary of the Invention

[0020] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Example 1, refer to Figures 1-15 An automated pipe welding device includes a processing table 1. The upper end of the processing table 1 is provided with a Y-axis adjustment assembly 2, a support assembly 3, and an X-axis adjustment assembly 4. The support assembly 3 includes a processing plate 31, which is connected to a slide rail 32. Above the processing plate 31 are a fixing assembly 5, a welding gun 7, and a Z-axis adjustment assembly 8. The fixing assembly 5 is fixedly connected to a pipe 10. The device also includes: Vibration assembly 6 is located above processing plate 31. Vibration assembly 6 uses reciprocating hammering vibration to reduce the mechanical stress generated in pipe 10 during welding. Heating component 9 is fixedly connected to vibration component 6. Heating component 9 reduces temperature difference by heating pipe 10 to improve welding quality.

[0022] Furthermore; one end of the processing table 1 is fixedly connected to the Y-axis adjustment component 2, the upper end of the Y-axis adjustment component 2 is movably connected to the X-axis adjustment component 4, the other end of the processing table 1 is fixedly connected to the Z-axis adjustment component 8, and the Z-axis adjustment component 8 is fixedly connected to the welding gun 7; the processing plate 31 is fixedly connected to the X-axis adjustment component 4, the upper surface of the processing plate 31 is fixedly connected to the slide rail 32, and the upper side wall of the processing plate 31 is provided with a slide groove 33; the fixing component 5 includes a motor 51, a positioning chuck 52 and a top seat 53, one end of the motor 51 is fixedly connected to the positioning chuck 52, the side wall of the positioning chuck 52 away from the motor 51 is provided with a slot 521, the motor 51 is located on one side of the slide rail 32, the top seat 53 is rotatably connected to a bearing seat 54, one end of the bearing seat 54 is fixedly connected to an electric sliding plate 55, the electric sliding plate 55 is slidably connected to the slide rail 32, and the side wall of the bearing seat 54 is provided with a mating hole 541.

[0023] It should be noted that: the Y-axis adjustment component 2 is located on the upper side of one end of the processing table 1. The main function of the Y-axis adjustment component 2 is to adjust the front and back position of the processing plate 31, and to control the front and back movement of the X-axis adjustment component 4 through the drive device and the threaded rod, so as to better move the pipe 10 directly below the welding gun 7. The Z-axis adjustment component 8 drives the plate to move through the drive device and the threaded rod, so as to realize the up and down adjustment of the welding gun 7 on the plate, thereby facilitating the control of the welding gun 7 to weld the welding end. In addition, in order to adjust according to the position of different welding points, the drive device and the threaded rod on the X-axis adjustment component 4 can drive the processing plate 31 to move left and right above the Y-axis adjustment component 2, thereby improving the adaptability of the welding process and expanding the application range. In addition, before welding, one end of the pipe 10 is passed through the vibration assembly 6 and fixed by the positioning chuck 52. After the other end of the other pipe 10 to be welded is joined at the welding end, the top seat 53 is controlled by the electric sliding plate 55 to press and fix the two sections of pipe 10, thereby achieving the positioning of the pipe 10. The inner diameter of the mating hole 541 is larger than the outer diameter of one end of the limiting slide rod 93. This ensures that when welding shorter pipes 10, the movement of the top seat 53 will not be affected by the mutual limiting between the limiting slide rod 93 and the bearing seat 54. After the limiting slide rod 93 passes through the mating hole 541, it is slidably connected to the slide groove 33 through the support bar 94 and the thrust of the electric sliding plate 55, thereby adjusting the position of the support bar 94 on the limiting slide rod 93. This controls the movement range of the limiting moving plate 92. The advantage of this is that it avoids the electric heating tube 921 from exceeding the length of the pipe 10 and doing useless work, and it can also improve the heating speed and efficiency.

[0024] Reference Figures 8-10 Furthermore, the vibration assembly 6 includes a rotating ring 61, a fixed ring 62, and a second electric sliding plate 63. The lower end of the second electric sliding plate 63 is slidably connected to the slide rail 32. A support block 621 is fixedly connected to the upper side wall of the second electric sliding plate 63. The upper end of the support block 621 is fixedly connected to the outer wall of the fixed ring 62. The rotating ring 61 is located on one side of the fixed ring 62. A pressing plate 611 and a magnet 612 are fixedly connected to the inner wall of the rotating ring 61. A support rod 613 is fixedly connected to the rotating ring 61. An extension ring 66 is provided on the side of the fixed ring 62 near the positioning chuck 52. The outer wall of the 6 is fixedly connected with a retaining ring 661. A connecting rod 662 is provided between the extension ring 66 and the fixed ring 62. Several connecting rods 662 are provided. The two ends of the connecting rod 662 are fixedly connected to the side walls of the extension ring 66 and the fixed ring 62, respectively. The vibration assembly 6 also includes a docking ring 65. A groove 652 is opened on the inner side wall of the docking ring 65. A plug rod 651 corresponding to the slot 521 is fixedly connected to one side of the docking ring 65. The groove 652 and the retaining ring 661 limit the sliding. The outer wall of the docking ring 65 is fixedly connected to the end of the support rod 613 away from the rotating ring 61.

[0025] It should be noted that after the two pipes 10 to be welded are fixed, the electric sliding plate 63 moves and positions itself on the slide rail 32, causing the insertion rod 651 to be inserted into the slot 521, thereby positioning the fixing ring 62. The purpose of this is to enable the docking ring 65 and the rotating ring 61 to rotate simultaneously with the rotation of the positioning chuck 52 and the pipe 10 driven by the motor 51. The rotation of the two is ensured by the mutual limiting sliding of the slot 652 and the retaining ring 661. The positioning of the electric sliding plate 63 can prevent the insertion rod 651 from falling out of the slot 521 during processing, thus ensuring the safety of processing. In addition, in the initial state, the positions of magnet 612 and magnet 642 are misaligned in space, and the magnetic field effect between them is weak in the initial position and will not drive the rotating ring 61 to rotate actively. Furthermore, the end of magnet 612 located inside the rotating ring 61 has a different polarity from the upper end of magnet 642.

[0026] Support rod 613: The two ends of the support rod 613 are fixedly connected to the rotating ring 61 and the docking ring 65 respectively. The main advantage of doing so is to provide external force support for the rotating ring 61 and fix it. At the same time, the synchronous rotation of the rotating ring 61 and the docking ring 65 can be achieved through the connection of the support rod 613, so as to ensure the periodic operation of the hammer rod 68.

[0027] Reference Figures 11-14 Furthermore, the vibration assembly 6 also includes a fixed column 64, one end of which is fixedly connected to the outer wall of the fixed ring 62. The fixed column 64 has a movable groove 647 inside, which is cylindrical. The movable groove 647 has limit grooves 646 on its two inner walls that are symmetrical about the central axis. The limit grooves 646 are elongated. The upper inner wall of the movable groove 647 has a pressing groove 645, which is an isosceles trapezoid. The cross-section of the movable groove 647 is stepped. The movable groove 647 has a hammer rod 68 and a buffer spring 69 inside. The hammer rod 68 is T-shaped. A T-shaped block 681 is fixedly connected to the upper end of the hammer rod 68. The buffer spring 69 is sleeved on the outer wall of the hammer rod 68. The two ends of the buffer spring 69 are fixedly connected to the side wall of the hammer rod 68 and the inner wall of the movable groove 647, respectively. The hammer rod 68 is slidably connected to the inner wall of the movable groove 647. The movable groove 647 is internally equipped with a lifting assembly 67, which includes a limiting seat 671 and locking rods 673. A pair of locking rods 673 are provided, with one end of each rod 673 rotatably connected to the limiting seat 671. A return spring 672 is provided between the two locking rods 673, with both ends of the return spring 672 fixedly connected to the opposite sidewalls of the two locking rods 673. The locking rods 673 are slidably connected to the limiting groove 646, and the limiting seat 671 is slidably connected to the inner wall of the movable groove 647. A movable rod 644 is fixedly connected to the upper end of the seat 671. One end of the movable rod 644 vertically penetrates the inner wall of the movable groove 647. A telescopic spring 643 is sleeved on the end of the movable rod 644 located outside the fixed column 64. A pressing block 641 is fixedly connected to the end of the movable rod 644 away from the limiting seat 671. A magnet 642 is fixedly connected to the pressing block 641. The two ends of the telescopic spring 643 are fixedly connected to the side wall of the fixed column 64 and the side wall of the pressing block 641, respectively. It should be noted that during the rotation of the rotating ring 61, magnet 612 attracts magnet 642 closer. At this time, due to the upward movement of the pressing block 641, the telescopic spring 643 is stretched, and through the connection of the movable rod 644, the lifting assembly 67 is moved upward as a whole. When magnet 612 and magnet 642 are in contact, the hammer rod 68 loses its limiting function. And when the hammer rod 68 is limited, the buffer spring 69 is in a stretched state. Therefore, after the hammer rod 68 loses its limiting function, its own weight and the action of the buffer spring 69 will cause the lower end of the hammer rod 68 to punch out of the movable groove 647 and strike and vibrate the outer wall of the pipe 10, thereby releasing the residual stress of the pipe 10 during the welding process. The force generated by the hammering is reduced, thereby reducing stress concentration, improving the stability and durability of the welded structure, and making the weld joint more tightly bonded, increasing the bonding area between the weld and the base material, thereby improving the effective load-bearing capacity and fatigue resistance of the weld joint. At the same time, the hammering can make the weld surface more uniform, eliminate possible depressions or protrusions, make the weld shape regular and beautiful, and improve its mechanical properties. In addition, the force generated by each hammering vibration is within a controllable range, and will not cause misalignment at the weld due to vibration. Therefore, in the process of welding pipe 10, appropriate hammering can not only eliminate residual stress, improve weld formation, and enhance the strength of the weld joint, but also improve the mechanical properties of the material. Furthermore, during the impact vibration process, the impact potential energy of the hammer rod 68 gradually decreases due to the resistance, eventually causing the hammer rod 68 and the buffer spring 69 to be in a relatively static state. During this process, the continuous rotation of the rotating ring 61 causes the magnet 612 and magnet 642 to separate, and also causes the arc-shaped surface of the extrusion plate 611 to press against the extrusion block 641, compressing the telescopic spring 643. This process also causes the lifting assembly 67 to move down through the movable rod 644, thereby re-clamping the hammer rod 68. The elasticity of the two telescopic springs 643 is greater than that of the buffer spring 69. After the lowest point of the extrusion plate 611 passes the extrusion block 641, the elastic recovery of the telescopic springs 643 causes the hammer rod 68 to move to the initial position to await the next release impact. This periodic vibration is used to improve the welding quality of the pipe 10.

[0028] Lifting Component 67: The lifting component 67 is crucial for achieving the striking vibration. It consists of a limiting seat 671, a return spring 672, and a locking rod 673 because each component has a specific function. The limiting seat 671 primarily ensures the stability of the locking rod 673 during operation. Simultaneously, it ensures the locking rod 673 rotates by sliding its curved end against the inner wall of the pressing groove 645 during its upward movement. This rotation compresses the return spring 672, and the locking rod 673 no longer clamps the T-block 681, thus causing the hammer rod 68 to lose its grip. The limiting seat 671 not only limits the movement of the clamping rod 673 during its operation but also provides sufficient space to ensure the movement of the clamping rod 673. As the limiting seat 671 moves downward, the clamping rod 673 separates from the extrusion groove 645. At this time, the clamping rod 673 is reset by the elastic recovery of the return spring 672. The chamfer at the lower corner of the clamping rod 673 is designed to allow the clamping rod 673 and the T-shaped block 681 to slide against each other, ensuring that the clamping opening of the clamping rod 673 opens and works with the return spring 672 to clamp the T-shaped block 681, ultimately resetting the hammer rod 68.

[0029] Example 2, refer to Figures 5-7 Furthermore, the heating assembly 9 includes a second telescopic spring 91, a limiting moving plate 92, and a limiting slide rod 93. The second telescopic spring 91 and the limiting moving plate 92 are both sleeved on the outer wall of the limiting slide rod 93. The limiting moving plate 92 is slidably connected to the limiting slide rod 93. One end of the limiting slide rod 93 is fixedly connected to the side wall of the fixing ring 62. Both ends of the second telescopic spring 91 are fixedly connected to the side wall of the fixing ring 62 and the side wall of the limiting moving plate 92, respectively. A support bar 94 is slidably connected to the outer wall of the limiting slide rod 93. The lower end of the support bar 94 is slidably connected to the slide groove 33. An electric heating tube 921 is provided at the upper end of the limiting moving plate 92. A magnet 922 is fixedly connected to the lower end of the limiting moving plate 92 near the fixing ring 62.

[0030] It should be noted that during the rotation of the rotating ring 61, magnet 612 will gradually approach magnet 922. Since the end of magnet 612 approaching magnet 922 has the same polarity as the end of magnet 922, the distance between magnet 612 and magnet 922 is closest when magnet 612 is at the lowest point of the rotating ring 61. During this process, due to the repulsion of like poles, the limiting moving plate 92 will move away from the fixed ring 62 and stretch the second telescopic spring 91. Furthermore, while the welding gun 7 is used to rotate and weld the pipe 10, the electric heating element 921 is turned on. Therefore, when magnet 612... When the extension spring 91 moves away from the magnet 922, the elastic recovery of the extension spring 91 causes the limiting moving plate 92 to move closer to the fixed ring 62. Due to inertia, the extension spring 91 is also compressed, thereby expanding the heating area and achieving heating treatment of the pipe 10 during welding. The multiple magnets 612 can achieve multiple reciprocating movements of the limiting moving plate 92 to ensure the heating effect. The welding gun 7 can also be retracted after welding to heat the pipe, thereby reducing the temperature difference between the welding area and the overall temperature of the workpiece, reducing welding stress and strain rate, and thus reducing the risk of welding deformation and cracks.

[0031] It should be noted that the specific model and specifications of the motor need to be selected and determined based on the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be described in detail here.
