[0033] The correction structure 3 includes two lifting plates 31, which are located on the surface of the support rod 13. The two ends of the lifting plates 31 extend into the limit groove 26 of the support rod 13 for slidable limit connection. The internal transmission screw 25 passes through the lifting plates 31, and the transmission screw 25 is threadedly connected to the lifting plates 31. The top surfaces of the lifting plates 31 on both sides are rotatably provided with auxiliary rollers 32. The direction of the auxiliary rollers 32 is parallel to the buffer roller 14 on one side, and the top surfaces of the auxiliary rollers 32 and the buffer roller 14 are located in the same horizontal plane. The outer surfaces of the lifting plates 31 on both sides are fixedly connected with electric telescopic rods 33. The output ends of the electric telescopic rods 33 pass through the lifting plates 31 and extend above the conveying roller 12. The output ends of the electric telescopic rods 33 are fixedly connected with the setting plates 34, and the sides of the setting plates 34 on both sides are rotatably provided with magnetic rollers 35. The setting plates 34 are provided with electric control equipment inside, which can drive the magnetic rollers 35 to rotate and give them magnetism.

[0034] The bottom surface of the top plate 15 is provided with an auxiliary structure 4, and a fixing rod 41 of the auxiliary structure 4 is fixedly connected to the bottom surface of the top plate 15. The bottom end of the fixing rod 41 is fixedly connected with a double-headed cylinder 42, which is square in shape, and a gap is left between the bottom end of the double-headed cylinder 42 and the conveying roller 12, and the gap between them is adapted to the height of the box-shaped steel connecting plate 6. The output ends of the double-headed cylinder 42 on both sides extend in the direction of the lifting plates 31 on both sides, and the output ends of the double-headed cylinder 42 are fixedly connected with a push plate 43, and the push plates 43 on both sides are rotatably provided with support rollers 44 on one side close to the correction structure 3.

[0035] The surfaces of the two support rods 13 away from the transmission motor 21 are fixedly connected with the welding structure 5, and the mounting frame 51 of the welding structure 5 is fixedly connected to the opposite side of the two support rods 13. The surface of the mounting frame 51 is fixedly connected with a hydraulic cylinder 52, and the output ends of the two hydraulic cylinders 52 are arranged along the direction close to the fixed rod 41. The output ends of the two hydraulic cylinders 52 are fixedly connected with welding pens 53, and the welding pens 53 on both sides are arranged toward the central vertical plane of the support structure 1.

[0036] When using this box-shaped steel component welding, assembly and correction equipment, the box-shaped steel connecting plate 6 is placed on the top surface of several conveying rollers 12, and the bottom of the double-headed cylinder 42 fixes the position of the box-shaped steel connecting plate 6. Then, the two box-shaped steel side plates 7 to be welded are moved to the top surface of the buffer roller 14 and the auxiliary roller 32 through an external driving device, and the box-shaped steel side plates 7 are moved to both sides of the top surface of the box-shaped steel connecting plate 6. Then, the transmission is carried out through the transmission structure 2, and the output end of the transmission motor 21 of the transmission structure 2 drives the rotating shaft 22 to rotate. During the rotation of the rotating shaft 22, the active bevel gear 23 on the surface is driven to rotate, thereby driving the meshing driven bevel gear to rotate. When the driven bevel gear rotates, it drives the four transmission screws 25 connected to rotate. The lifting plate 31 with threads passing through the surface of the transmission screw 25 is subjected to the thread force and the limiting effect of the limiting groove 26, and begins to lift on the outside of the two support rods 13. During the process of the lifting plate 31 rising, the auxiliary roller 32 on the top surface of the lifting plate 31 and the bottom surface of the box-shaped steel side plate 7 rotate relative to each other around the buffer roller 14, so that the box-shaped steel side plates 7 on both sides rotate and tilt in the direction close to the box-shaped steel connecting plate 6. During the rotation of the box-shaped steel side plates 7, the box-shaped steel side plates 7 may fall down at an accelerated speed due to their own gravity. At this time, the double-headed cylinder 42 of the auxiliary structure 4 is started, and the output end of the double-headed cylinder 42 drives the push plate 43 to move, so that the support roller 44 on the surface of the push plate 43 moves to the side close to the box-shaped steel side plate 7. When the box-shaped steel side plate 7 falls down at an accelerated speed, it will contact the surface of the support roller 44. With the subsequent rotation driven by the lifting plate 31 and the rotation of the support roller 44 itself, the box-shaped steel side plate 7 slowly rotates to the top surface of the box-shaped steel connecting plate 6, avoiding the box-shaped steel top surface from being bumped due to excessive speed during the rotation process. During the process of the lifting plate 31 rising, the box-shaped steel side plates 7 may rotate excessively and exceed the originally set vertical direction. When the lifting plate 31 rises to a certain extent, the electric telescopic rod 33 on the surface of the lifting plate 31 is started, and the output end of the electric telescopic rod 33 drives the setting plate 34 and the magnetic roller 35 to contact the outer surface of the box-shaped steel side plate 7. The electric control device inside the setting plate 34 makes the magnetic roller 35 itself adhere to magnetism, so that the magnetic roller 35 and the surface of the box-shaped steel side plate 7 are mutually adsorbed. Since the magnetic roller 35 itself adheres to magnetic force and can rotate, the lifting plate 31 is in a continuous rising stage at this time. As the setting plate 34 rises, the magnetic roller 35 rotates with it and is always magnetically adsorbed with the surface of the box-shaped steel side plate 7, preventing the box-shaped steel side plate 7 from rotating excessively beyond the originally set vertical plane. When the lifting plate 31 rises, the auxiliary roller 32 provides the box-shaped steel side plate 7 with an upward rotation force, and the horizontal magnetic roller 35 provides the box-shaped steel side plate 7 with a horizontal force, so that the box-shaped steel side plate 7 can rotate smoothly. At the same time, the magnetic roller 35 itself can prevent the box-shaped steel side plate 7 from rotating excessively.By starting the double-headed cylinder 42 of the auxiliary structure 4, the output end of the double-headed cylinder 42 drives the push plate 43 and the support roller 44 to move back and forth, pushes the bottom end of the box-shaped steel side plate 7, and moves the bottom end of the box-shaped steel side plate 7 to the designated welding position. When the lifting structure drives the box-shaped steel side plate 7 to rotate to the vertical direction on both sides of the box-shaped steel connecting plate 6, the auxiliary structure 4 adjusts the position of the box-shaped steel side plate 7 and assists in the rotation. Then, the welding of the box-shaped steel connecting plate 6 and the box-shaped steel side plate 7 is completed through the welding structure 5, and the hydraulic cylinders 52 on both sides are started. The output end of the hydraulic cylinder 52 drives the welding pen 53 to move, and the welding pen 53 moves to the welding position of the box-shaped steel side plate 7 and the box-shaped steel connecting plate 6, and the welding pen 53 is started at this time for welding. During the welding process, the hydraulic cylinder 52 is continuously started, so that the welding pen 53 welds the box-shaped steel side plate 7 and the box-shaped steel connecting plate 6 to form a straight weld, thereby allowing the box-shaped steel side plate 7 and the box-shaped steel connecting plate 6 to be initially stabilized. Then the output end of the hydraulic cylinder 52 drives the welding pen 53 to retract, and starts several conveying rollers 12 inside the bottom plate 11, and the conveying rollers 12 move the box-shaped steel connecting plate 6 and the box-shaped steel side plate 7 that have been initially fixed. At this time, the welding pen 53 on both sides is started, and the initially fixed box-shaped steel moves relative to the welding pen 53 on both sides during the movement process, so that the welding pen 53 on both sides welds the remaining unwelded parts. In this way, the welding and fixing between the box-shaped steel side plate 7 and the box-shaped steel connecting plate 6 are completed. After the welding and fixing are completed, it is taken out. At this time, the partial correction welding of the box-shaped steel has been completed. The box-shaped steel sheets are directly positioned and welded on the top surface of the box-shaped steel side plates 7 on both sides, and the standardized welding and forming of the box-shaped steel is completed.

[0037] Working principle of the present invention: A box-shaped steel member welding assembly correction device of the present invention is provided with a support structure 1 and a correction structure 3. The box-shaped steel side panels 7 on both sides are moved to the top surface of the box-shaped steel connecting plate 6 by the auxiliary rollers 32 of the correction structure 3. Then, the lifting plates 31 on both sides are lifted, and the box-shaped steel side panels 7 are driven to rotate around the buffer rollers 14 by the auxiliary rollers 32 on the top surface; the setting plate 34 and the magnetic roller 35 connected to the lifting plate 31 can adsorb the surface of the box-shaped steel side panels 7, and avoid excessive rotation beyond the vertical plane during the rotation process, and at the same time, the electric telescopic rod 33 is extended and retracted to drive the box-shaped steel side panels 7 outward Pull; by setting up an auxiliary structure 4, the double-headed cylinder 42 of the auxiliary structure 4 can drive the push plate 43 to extend and retract, and the support roller 44 on the surface of the push plate 43 can push the bottom of the box-shaped steel side panel 7 back and forth, thereby moving the bottom end of the box-shaped steel side panel 7 to the designated installation position; the box-shaped steel side panel 7 will suddenly fall due to the action of gravity during the rotation process, and by moving the position of the push plate 43, the box-shaped steel side panel 7 can directly fall on the surface of the support roller 44 when it falls, and then as the push plate 43 moves, the support roller 44 is driven to rotate, allowing the box-shaped steel side panel 7 to slowly rotate to the two sides of the box-shaped steel top plate 15 for buffering. By setting up a welding mechanism, the welding pen 53 of the welding mechanism is moved by the hydraulic cylinder 52, and the welding pen 53 will first perform linear welding on both sides of the box-shaped steel side plate 7 and the box-shaped steel connecting plate 6, so as to preliminarily fix them; then the hydraulic cylinder 52 drives the welding pen 53 to retract, and the conveying roller 12 below drives the preliminarily welded box-shaped steel to move, and the box-shaped steel and the welding pen 53 move relative to each other to complete the welding of the remaining positions, thereby completing the positioning welding of the three sides of the box-shaped steel, and welding the steel plates on the remaining surfaces to complete the standardized production of the box-shaped steel.
