[0002] Box girder is a common structural form, consisting of two parallel steel plates (usually rectangular or trapezoidal), connected together by longitudinal and transverse connectors. Box girders are commonly used in bridges, building structures, mechanical equipment and other fields, and are characterized by high strength and rigidity. Steel plates are one of the important components of box girders. They are usually made of high-strength steel to ensure the bearing capacity and stability of the box girder. Steel plates can be customized and processed according to specific design requirements and application scenarios, such as cutting, bending, welding, etc.

[0003] During the manufacturing process of the box girder, the steel plates need to be welded to achieve connection and fixation. When welding the box girder steel plates, the two steel plates need to be aligned for welding. The existing alignment method requires welders to manually align the two steel plates. This alignment method is too cumbersome and time-consuming. In addition, manual alignment is also prone to introduce errors, thereby affecting the welding quality. Utility Model Content

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Reference Figure 1 , Figure 2 and Figure 5 , the utility model provides an embodiment: an auxiliary device for welding box girder steel plates, including a welding table 1, a motor 5 is arranged at the lower part of the welding table 1, a rotating shaft 6 is fixedly connected to the output end of the motor 5, a gear 7 is fixedly connected to the outside of the rotating shaft 6, rack plates 8 are fixedly connected to the outside of the gear 7 on both sides, the lower parts of the two rack plates 8 are fixedly connected to sliders 9, the upper parts of the two rack plates 8 are fixedly connected to mounting rods 11, the tops of the two mounting rods 11 are fixedly connected to cross plates 12, the lower parts of the two cross plates 12 are fixedly connected to guide rings 13, the upper parts of the two cross plates 12 are fixedly connected to fixed plates 15 on both sides, and the outer parts of the plurality of fixed plates 15 are provided with fixing components 16, the lower part of the welding table 1 is fixedly connected to an L-shaped plate 4, the motor 5 is fixedly connected to the upper part of the L-shaped plate 4, slide grooves 10 are opened on both sides of the upper part of the welding table 1, two slide blocks 9 are slidably connected to the inside of the two slide grooves 10, the upper parts of the welding table 1 are fixedly connected to guide rods 14, and the two guide rings 13 are slidably connected to the outside of the two guide rods 14.

[0026] When two steel plates need to be aligned, first fix the two steel plates in the middle of four positioning plates 1606. These positioning plates 1606 are made of high-strength materials to ensure the stability of the steel plates during welding. Next, start the motor 5. Its output end is fixedly connected to the rotating shaft 6. When the motor 5 is started, the rotating shaft 6 starts to rotate, driving the external fixed gear 7 to rotate. The rotation of the gear 7 realizes the transmission of power through the rack plates 8 on both sides thereof. Since the rack plate 8 is meshed and connected with the gear 7, the rotation of the gear 7 will drive the relative movement of the rack plate 8. The movement of the two rack plates 8 further drives the relative movement of the two mounting rods 11 fixedly connected at the upper part. These two mounting rods 11 are one of the key components of the entire device, and their movement trajectory determines the alignment accuracy of the steel plates. The movement of the mounting rod 11 is transmitted through the cross plate 12, and four fixed plates 15 are fixedly connected on both sides of the upper part of the cross plate 12. During the movement of these fixed plates 15, the two steel plates fixed in the middle are driven to move relative to each other, so that the two steel plates to be welded gradually contact and align, thereby realizing automatic alignment of the steel plates to be welded without the need for manual alignment by welders. This alignment method is simple and convenient to operate, saves time and effort, and improves the welding efficiency of the steel plates.

[0027] Reference Figure 3 and Figure 4The fixed component 16 includes an electric push rod 1601, which is fixedly connected to the outside of multiple fixed plates 15. A moving block 1602 is fixedly connected to the output end of the electric push rod 1601. Adjustment rods 1603 are rotatably connected to both sides of the outside of the moving block 1602. Through holes 1608 are opened on both sides of the inside of the fixed plate 15. Fixed rods 1607 are fixedly connected to the inside of the two through holes 1608. Sliding blocks 1604 are slidably connected to the outside of the two fixed rods 1607. Connecting rods 1605 are fixedly connected to the outside of the two sliding blocks 1604. Positioning plates 1606 are fixedly connected to the outside of the two connecting rods 1605. Protective pads 17 are arranged inside the two positioning plates 1606. The material of the protective pads 17 is rubber.

[0028] During the process of fixing the steel plate, first, the steel plate to be fixed is placed in the middle of the four positioning plates 1606. Next, the two electric push rods 1601 are started, and the output ends of the two electric push rods 1601 are fixedly connected to the two moving blocks 1602. When the electric push rods 1601 are started, the moving blocks 1602 will move accordingly. The outer ends of the moving blocks 1602 are connected to four adjustment rods 1603 by rotation, so when the moving blocks 1602 move, the four adjustment rods 1603 will also move accordingly. The other ends of these adjustment rods 1603 are connected to four sliding blocks 1604 by rotation, and the four sliding blocks 1604 move relatively outside the four fixed rods 1607. This design allows us to make fine adjustments according to the size and shape of the steel plate to ensure that the steel plate can be firmly fixed in place. When the two sliding blocks 1604 move relative to each other, they will drive the four connecting rods 1605 fixedly connected to the outside to move relative to each other. The other ends of the four connecting rods 1605 are fixedly connected to four positioning plates 1606, so when the connecting rods 1605 move, the positioning plates 1606 will also move accordingly. This chain reaction design allows us to accurately adjust the position of the positioning plates 1606 to adapt to steel plates of different sizes and shapes. During the relative movement of the four positioning plates 1606, they will move relative to each other with the four external protective pads 17 to fix the steel plates. The protective pads 17 are made of rubber material, which can not only protect the surface of the steel plate from damage, but also provide sufficient friction to ensure that the steel plate will not slide or shake during the fixing process. For another steel plate that needs to be fixed, repeat the above operation, so that it is easy to fix the steel plate that needs to be welded. Fixing the steel plate can ensure the stability of the steel plate during welding and reduce welding defects caused by movement or shaking. Stable workpieces can provide better welding conditions, making the weld more uniform and firm, thereby improving welding quality.
