Description

Technical Field

[0001] The utility model relates to the technical field related to steel structure welding brackets, in particular to a conveniently clamped steel structure welding bracket. Background Art

[0002] With the development of science and technology, the application of steel structures in construction projects in the world is becoming more and more extensive. Welding is a very important processing technology in steel structure manufacturing. According to statistics from industrially developed countries, steel that needs to be used only after welding accounts for about 45% of steel production each year. The steel structure welding bracket is used as equipment for steel structure welding processing, which also plays a very important role in steel structure welding.

[0003] Prior art publication number CN216370825U discloses a steel structure welding bracket, which belongs to the technical field of steel structure welding brackets, and includes a workbench. When a circular steel structure needs to be welded, two cylinders push two movable plates according to the diameter of the circular steel structure, and the two movable plates move closer or farther away from each other, thereby clamping the circular steel structure, thereby realizing flexible clamping of circular steel structures of different diameters, thereby facilitating subsequent welding. When a square steel structure needs to be welded, the square steel structure is located between a fixed clamping plate and a movable clamping plate, and a motor drives the lead screw to rotate, causing the movable clamping plate to move back and forth under the action of a slider, until the distance between the movable clamping plate and the fixed clamping plate is just enough to limit and fix the square steel structure, thereby realizing the effect of clamping and fixing square steel structures of different diameters, thereby achieving the goal of one device being able to simultaneously weld two different steel structures.

[0004] Although the above-mentioned method has certain advantages in flexible clamping and fixing of square steel structures of different diameters, it still has certain disadvantages;

[0005] 1. When welding steel structures, it is often necessary to adjust the welding distance between the steel structures in advance before fixing them, and quick and efficient micro-adjustments cannot be made after they are fixed.

[0006] 2. When the welding angle needs to be adjusted, the angle cannot be adjusted manually after the equipment is fixed to the steel structure. It is relatively troublesome to release the fixation before adjustment. Utility Model Content
