Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model. Example

[0019] Please see Figures 1-5 This utility model provides a technical solution: an automatic double-gun welding device for bridge steel sections, including a workbench 1, a first material platform 2, and a second material platform 3. Three mounting seats are fixedly installed on the top outer wall of the workbench 1. Each of the three mounting seats has a first adjusting handwheel 5 on its outer wall. Each of the three first adjusting handwheels 5, located inside the three mounting seats, has an adjusting screw 7 on its outer wall. Each of the three adjusting screws 7 has an adjusting pressure roller 6 movably installed on its outer wall. Each of the three mounting seats has a main drive guide roller 8 fixedly installed on its inner wall above the adjusting screws 7. Each of the three mounting seats has a second adjusting handwheel 9 on its outer wall above the first adjusting handwheels 5. Each of the three second adjusting handwheels 9, located inside the three mounting seats, has a coupling 11 on its outer wall. The three couplings 11 are respectively connected to the three mounting seats. Connecting shafts 12 are provided between the inner walls of the three mounting bases. Lifting machines 10 are provided on the top outer walls of the three mounting bases and at the couplings 11. Lifting machines 10 are used to adjust the height of the connecting shafts 12. A variable frequency reduction motor 13 is fixedly installed on the outer wall of one of the mounting bases. Support plates are provided on the inner walls of the three mounting bases. Sprockets are fixedly installed on the top outer walls of the three support plates and the output end of the variable frequency reduction motor 13. Chains are provided between the sprockets. Welding guns 15 are provided on both sides of the workbench 1. An electrical cabinet 14 is fixedly installed on the top outer wall of the workbench 1 for intelligent control. The three main drive guide rollers 8 are connected in series through sprockets and chains. The three main drive guide rollers 8 are synchronously driven to rotate by the variable frequency reduction motor 13. The first adjusting handwheel 5 is used to adjust the width of the pressure roller 6 in the left and right directions.

[0020] In this implementation scheme, the workpiece passes through a set of upper and lower guide rollers and a set of left and right guide rollers in the middle, while welding is performed simultaneously by a welding gun on both sides. The workpiece is driven by three sets of upper and lower and left and right guide rollers, which ensures that the workpiece to be welded is pressed tightly, the welding is not deformed, and the welding deformation is reduced by the simultaneous welding of two guns. This improves welding efficiency, simplifies operation, and produces a beautiful weld. For left and right pressing and guiding: three sets of main drive guide rollers 8 are connected in series by sprockets and chains and are synchronously driven to rotate by a variable frequency reduction motor 13; on the other side, three sets of independent adjusting pressure rollers 6 press the workpiece in the width direction and ensure that the workpiece is pressed and driven in the left and right directions, and presses and guides in the up and down directions; three sets of lower guide rollers are fixedly installed and do not require adjustment, and three sets of upper pressure rollers are adjusted by a second adjusting handwheel 9. The left and right sets are connected in series by a coupling 11 to ensure the synchronicity of height adjustment.

[0021] Working principle: The workpiece passes through a set of upper and lower guide rollers and a set of left and right guide rollers in the middle. Welding is performed simultaneously by two welding guns on both sides. The workpiece is driven by three sets of upper and lower, left and right guide rollers, ensuring that the workpiece is pressed firmly, the welding process is deformation-free, and the simultaneous welding by two guns reduces welding deformation. This improves welding efficiency, simplifies operation, and produces aesthetically pleasing welds. Left and right pressing and guiding: Three sets of main drive guide rollers 8 are connected in series via sprockets and chains, and are synchronously driven by a variable frequency reduction motor 13. On the other side, three sets of independent adjusting pressure rollers 6 press the workpiece in the width direction, ensuring left and right pressing and driving the workpiece. Up and down pressing and guiding: Three sets of lower guide rollers are fixedly installed and require no adjustment. Three sets of upper pressure rollers are adjusted via a second adjusting handwheel 9. The left and right sets are connected in series via couplings 11 to ensure synchronous height adjustment.
