[0002] Steel tube truss refers to a lattice structure composed of round rods connected at the ends. The truss structure uses economical materials, has a light weight, and is easy to form various shapes to adapt to different uses, such as simply supported trusses, arches, frames and towers. Compared with grid structures, steel structure trusses are important load-bearing components of structures such as bridges, and their firmness and stability are directly related to the safety and quality of the entire project.

[0003] When processing the circular steel tube truss, the existing equipment does not have a good device specifically for fixing and clamping the circular steel tube truss. Basically, each arc steel tube is manually placed, calibrated, connected with each other, and the square support frame is welded and installed, which not only brings great labor intensity to the staff.

The fixed sleeve drives the outer adjustment component, the fixing part and the arc steel pipe to rotate, so that the welding points can reach the welding position in sequence and in an orderly manner, which greatly reduces the moving time of the welding gun in the non-welding area and improves the welding efficiency. The outer side of the fixed sleeve is fixedly connected to a limit plate, and a through hole is opened on the outer side of the limit plate; A welding assembly, the welding assembly is fixedly mounted on a top side of the platform away from the fixing seat; An adjusting component, the adjusting component is fixedly mounted on the outside of the fixing sleeve, there are multiple adjusting components, and the multiple adjusting components are evenly distributed around the fixing sleeve; A fixing part, the fixing part is fixedly installed inside the adjusting component; Among them, the adjusting component includes a fixed frame, and there are multiple fixed frames. The outer side of the fixed frame is fixedly connected with a bending plate, and the bending plate is elastic. The arc steel pipe to be processed is initially clamped by the fixing piece. Since the adjacent fixed frames are connected by the bending plate, the movement of the adjusting roller can control the movement of the adjusting fixed frame, and then drive the bending plate to perform telescopic movement, so that the synchronous control of the adjusting component can be achieved. The position movement of the clamped arc steel pipe can be controlled to control the position between adjacent arc steel pipes, so that the two adjacent butt-jointed arc steel pipes can be accurately butt-jointed and installed together. By setting multiple adjusting components, whether it is a circular or elliptical truss, It can achieve precise positioning and stable fixation, ensuring that the truss will not be displaced or deformed during the welding process, thereby ensuring the quality and accuracy of the welding joint, improving the overall quality of the product, and then being able to adapt to the fixation needs of circular or elliptical trusses of different shapes and sizes, and improving the applicability of the equipment.

During the welding process, the steel pipe will have a tendency to deform due to uneven heating. The three-point clamping can effectively suppress the deformation of the steel pipe through uniform force constraint, so that the welded steel pipe maintains a good shape accuracy, reducing the workload of the subsequent correction process. It is particularly important for some welding structures that have strict requirements on deformation control.

[0019] The third embodiment is based on the first and second embodiments. Figures 7 to 10 As shown, the welding assembly 2 includes a slide rail 21, which is fixedly installed on the top of the platform 1. The top of the slide rail 21 is slidably connected to a moving block 22, and the outer side of the moving block 22 is slidably connected to a slider 23.

[0020] The welding part 27 includes a rotating wheel 271, which is rotatably connected to the positioning block 24, and the rotating wheel 271 is rotatably connected to the transmission belt 26. The end of the rotating wheel 271 away from the positioning block 24 is fixedly connected to the rotating shaft 272, and the end of the rotating shaft 272 away from the rotating wheel 271 is fixedly connected to the limiting block 273. A return spring 275 is arranged on the outer side of the rotating shaft 272, and a sliding block 274 is fixedly connected to the side of the return spring 275 close to the limiting block 273. The sliding block 274 is slidably connected to the outer side of the rotating shaft 272, and the end of the return spring 275 away from the sliding block 274 is fixedly connected to the positioning block 24. The motor 25 is connected to an external power supply to work, and the motor 25 works through the transmission belt 2 6 drives the rotating wheel 271 to rotate, and the rotating wheel 271 drives the rotating shaft 272 and the limit block 273 to rotate. The limit block 273 rotates and squeezes the sliding block 274. The return spring 275 is compressed, so that the sliding block 274 slides on the outside of the rotating shaft 272 in the direction away from the limit block 273, so that the welding piece 27 rotates. Due to the complex structure of the truss, the positions of the welds of the truss are diverse, and there are welds at various angles and positions, including vertical, horizontal, and inclined directions. The welding piece 27 can rotate in the vertical and horizontal directions, so that the welds can be evenly welded at different spatial positions to avoid excessive or insufficient welding in some areas. The situation ensures that the quality of the entire weld is uniform, and the accuracy and quality of welding are improved. The sliding block 274 is meshed with the limiting block 273. After adjusting the angle of the welding part 27, the elastic performance of the reset spring 275 is used to make the limiting block 273 and the sliding block 274 engage with each other, so as to avoid changes in the rotation angle of the welding part 27 during the welding process. The rotation positioning can accurately match the weld of the welding part with the position of the welding equipment or the operator, and can accurately adjust the weld to the optimal welding position, ensuring the docking accuracy between the welds, reducing problems such as misalignment and uneven gaps, thereby improving the quality of the welded joint and the accuracy of the overall structure.

[0021] When in use, the arc-shaped steel pipe to be processed is placed inside the fixing part 9, and extrusion is generated between the arc-shaped steel pipe and the bent plate 910. The force guide rod of the bent plate 910 moves toward the direction close to the fixed rod 91, so that the two ends of the bent plate 910 drive the connecting plates 911 on both sides to move, and the connecting plates 911 pull the arc plate 96 and the round rod 95 to slide inside the sliding hole 94, so that the clamping plates 98 on both sides and the bent plate 910 clamp the arc-shaped steel pipe.

[0022] The arc-shaped steel pipe to be processed is initially clamped by the fixing part 9. Since the adjacent fixing frames 81 are connected by the bending plate 82, the movement of the adjusting roller 83 can control the movement of the adjusting fixing frame 81, thereby driving the bending plate 82 to perform telescopic movement, so that the synchronous control adjustment component 8 can move the clamped arc-shaped steel pipe and control the position between adjacent arc-shaped steel pipes, so that the two adjacent arc-shaped steel pipes can be accurately docked and installed together.

[0023] According to the actual welding situation, the motor 25 is connected to an external power supply, and the motor 25 drives the rotating wheel 271 to rotate through the transmission belt 26. The rotating wheel 271 drives the rotating shaft 272 and the limit block 273 to rotate. The limit block 273 rotates and squeezes the sliding block 274. The reset spring 275 is compressed, so that the sliding block 274 slides on the outside of the rotating shaft 272 away from the limit block 273, so that the welding part 27 rotates, and the weld can be accurately adjusted to the optimal welding position, so that the welding gun 2711 can weld the arc steel pipe.

[0024] The motor 4 is connected to an external power source to work, and the motor 4 drives the fixed sleeve 3 to rotate. The fixed sleeve 3 drives the outer adjustment component 8, the fixing part 9 and the arc-shaped steel pipe to rotate, so that the welding points can reach the welding position in sequence and in an orderly manner, which greatly reduces the moving time of the welding gun in the non-welding area and improves the welding efficiency.
