However, in actual operation, the adjustment accuracy of the positioning clamps is limited, making it difficult to accurately align the welding points, resulting in low welding accuracy. Furthermore, the existing device requires frequent adjustments to the position of the positioning components when fixing steel structures of different sizes, showing poor adaptability.

Obviously, the specific embodiments described are only a part of the embodiments of this utility model, and not all of them.

[0015] Example: The following is in conjunction with the appendix Figure 1-3 The present invention will be described in further detail below.

[0016] Please see Figure 1-3This utility model provides a technical solution: a welding positioning auxiliary device for large-span irregular steel structures, including a workbench 1, a welding table 2, and a support frame 14. The welding table 2 is horizontally slidably fitted inside the workbench 1, and a drive assembly for controlling the horizontal sliding of the welding table 2 is provided on the workbench 1. Positioning components 3 are provided on the welding table 2, with multiple sets of positioning components 3 symmetrically arranged on the welding table 2. Each positioning component 3 includes a fixing plate 301 vertically welded to the welding table 2. A threaded sleeve 302 is threaded through the fixing plate 301, and a first threaded post 303 is threadedly connected to the threaded sleeve 302. The first threaded post 303 is parallel to the welding table 2. A positioning clamping plate 306 perpendicular to the welding table 2 is provided at the front end of the first threaded post 303. A first bearing 307 is fixedly connected to the side of the positioning clamping plate 306. A first rotating shaft 305 is provided at the front end of the first threaded post 303, and the first rotating shaft 305 passes through the first bearing 307. A handle 304 is fixedly connected to the tail end of the first threaded post 303. By rotating the handle 304, the first threaded post 303 rotates in the threaded sleeve 302, and the threaded transmission pushes the positioning clamp 306 to move inward, thereby clamping the steel structure. Multiple sets of positioning clamps 306 can clamp the irregular steel structure at multiple points, providing a stable clamping force to ensure that the steel structure will not be displaced during welding, thereby improving the welding accuracy and quality. A fixed platform 13 is provided on the side of the workbench 1. An L-shaped upright 14 is vertically fixed on the fixed platform 13. An electric push rod 15 is vertically fixed to the top of the upright 14. A welding head 16 is fixedly connected to the lower output end of the electric push rod 15. By adopting the above technical solution, the up and down movement of the welding head 16 can be precisely controlled by the extension and retraction of the electric push rod 15, so that it can be accurately aligned with the welding point of the steel structure, further improving the welding accuracy and reliability.

[0017] Specifically, the drive assembly includes a motor frame 4 mounted on the outside of the worktable 1, a drive motor 5 mounted on the motor frame 4, a second rotating shaft 6 fixedly connected to the output end of the drive motor 5, a second bearing 7 passing through the worktable 1, the second rotating shaft 6 passing through the second bearing 7, a second threaded post 8 fixedly connected to the front end of the second rotating shaft 6, the second threaded post 8 being parallel to the worktable 1, and a threaded tube 9 threadedly connected to the front end of the second threaded post 8, the front end of the threaded tube 9 being fixedly connected to the side of the welding table 2. By adopting the above technical solution, after the drive motor 5 starts, it drives the second threaded post 8 to rotate via the second rotating shaft 6. The threaded tube 9 moves along the second threaded post 8 under the action of the thread, thereby pushing the welding table 2 to move horizontally along the slide groove 12, realizing the automatic movement and position adjustment of the welding table 2. The operator only needs to start the drive motor 5 to complete the movement operation of the welding table 2.

[0018] Specifically, parallel grooves 12 are symmetrically formed on both sides of the workbench 1. Slider blocks 11 that match the grooves 12 are fixedly connected to both sides of the welding table 2. The welding table 2 is slidably fitted into the grooves 12 by the sliders 11. By adopting the above technical solution, the structural design of the grooves 12 and sliders 11 ensures that the welding table 2 remains stable during movement, avoiding shaking or displacement of the welding table 2.

[0019] Specifically, a slag-removing hole 10 is provided on the side of the workbench 1.

[0020] Specifically, a laser positioning device 17 is installed on the side of the welding head 16. The laser positioning device 17 can be precisely aligned with the welding point of the steel structure to ensure the precise docking of the welding head 16 with the welding point, thereby further improving the accuracy and quality of the welding.

[0021] Specifically, the four corners of the workbench 1 are fixedly connected with fixing ears 18, and the fixing ears 18 are provided with matching fixing bolts 19.

[0022] The working principle of this utility model is as follows: First, the entire device is fixedly installed in the designated position using fixing bolts 19. Then, the steel structure to be welded is placed on the welding table 2. By rotating the handles 304 in each positioning component 3, the first threaded column 303 is driven to rotate, pushing the positioning clamping plate 306 to move inward, thereby clamping the steel structure. Multiple positioning clamping plates 306 can clamp at different positions of the irregular steel structure, providing stable clamping. Next, the drive motor 5 is started. The output end of the drive motor 5 drives the second threaded column 8 to rotate through the second rotating shaft 6 and the second bearing 7. The threaded tube 9 at the front end is fixedly connected to the side of the welding table 2. The rotation of the threaded column pushes the welding table 2 to move horizontally along the slide 12. The sliders 11 on both sides of the welding table 2 match the slides 12 on both sides of the worktable 1 to ensure that the welding table 2 moves smoothly. With the assistance of the laser positioning instrument 17, the position of the steel structure is precisely adjusted so that its welding point is aligned with the welding head 16. Then, the electric push rod 15 is started, and the welding head 16 is lowered to the welding point of the steel structure for welding operation. After welding is completed, the electric push rod 15 lifts the welding head 16 and drives the motor 5 to rotate in the opposite direction to move the welding table 2 back to the initial position.

After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
