Description

Technical Field

[0001] This utility model belongs to the field of metal welding technology, and specifically relates to an adjustment device for butt welding of steel structures. Background Technology

[0002] During steel structure construction, pipes often need to be welded to the required length on site. When welding, the two pipes being joined must be aligned with the same axis. Since the pipes used in steel structures are generally heavy, handling and adjusting them is very inconvenient for workers, resulting in high labor intensity. Prolonged operation can lead to reduced efficiency and poorer welding quality.

[0003] Chinese patent application CN202321520082.3 discloses a steel structure welding device for adjusting the position of a steel structure. The device includes a base and a welding machine mounted on top of the base. Sliding plates slide on both sides of the top of the base, and centering and fixing components are provided on the sides of both sliding plates. These components are used for automatic centering and clamping of the steel structure tubes. By using these centering and fixing components, the device facilitates the rapid alignment and clamping of the centers of the two steel structure tubes before welding, improving welding quality. Furthermore, clamping the steel structure tubes does not affect their rotation. The drive component facilitates contact between the ends of the two steel structure tubes, simplifying the welding process. However, the centering and fixing components of the aforementioned device are complex. The steel structure needs to be horizontally passed through a circular groove during loading and unloading, requiring specialized equipment, which is time-consuming and labor-intensive. Moreover, the steel structure cannot rotate automatically during welding, making adjustments very inconvenient and affecting welding efficiency. Utility Model Content

[0004] To address the problems mentioned in the background section, this utility model provides a steel structure butt welding adjustment device that can conveniently and quickly clamp steel structure components and automatically adjust the welding position, thereby improving welding efficiency.

It also works with the fixing clamp device 6 to fix the steel part 7 and drive the steel part 7 to rotate, automatically adjusting the welding position and improving welding efficiency.

[0026] like Figure 3 , Figure 4 , Figure 5 As shown, one end of the positioning groove 301 has an installation groove 303, and a drive box device 304 is installed in the installation groove 303. The drive box device 304 is connected to the centering double roller device 8. The centering double roller device 8 consists of two horizontally arranged and symmetrically arranged support rollers. The centering double roller device 8 extends upward out of the positioning groove 301. Vertical lifting cylinders 305 are installed on the left and right sides of the lower end face of the adjustment plate 301. The lower ends of the two lifting cylinders 305 are fixedly connected to a support plate 306, which is located directly below the positioning groove 301.

[0027] The screw device 5 includes a sliding bracket 501, which is fixedly connected to the front and rear sides of the adjustment plate 3. A double-headed screw 502 is rotatably connected inside the sliding bracket 501, and a first motor 503 is connected to one end of the double-headed screw 502.

[0028] like Figure 6As shown, the lower end of the V-shaped positioning block 4 is fixedly connected to the support plate 306. The V-shaped positioning block 4 has an upward-opening V-shaped positioning groove 401. The lower end of the V-shaped positioning groove 401 has an avoidance groove 402. The avoidance groove 402 can prevent the V-shaped positioning block 4 from interfering with the centering double roller device 8.
