Technical Field

[0001] The utility model relates to the technical field of welding, in particular to a bracket for welding a steel structure. Background Art

[0002] Welding, also known as fusion, is a manufacturing process and technology that joins metals or other thermoplastic materials such as plastics by heating, high temperature or high pressure. There are many sources of energy for modern welding, including gas flame, arc, laser, electron beam, friction and ultrasound. In addition to being used in factories, welding can also be performed in a variety of environments, such as outdoors, underwater and in space. No matter where it is, welding may be dangerous to the operator, so appropriate protective measures must be taken when welding. The possible harm caused by welding to the human body includes burns, electric shock, visual impairment, inhalation of toxic gases, excessive ultraviolet radiation, etc.

[0003] When welding a square steel pipe, the square steel pipe is generally placed on a welding bracket and clamped and fixed by a limit assembly on the bracket so that the square pipe cannot move. However, when welding is required at other positions of the square pipe, it is either necessary to move it manually or to open the limit assembly and adjust the position before clamping, which is troublesome to operate. Utility Model Content

[0004] In view of the deficiencies in the prior art, the purpose of the utility model is to provide a bracket for steel structure welding, which has the effect of clamping and limiting the square steel pipe while not delaying the horizontal movement of the square steel pipe to adjust the welding position, making it more convenient to use.

[0008] The utility model can be further configured as follows in a preferred example: each group of the clamping mechanism includes a rectangular groove, a bidirectional screw, a motor and two screw nuts, the rectangular groove is opened at the upper end of the mounting plate, the bidirectional screw is rotatably connected to a side wall of the rectangular groove, and the bidirectional screw movably passes through one side of the mounting plate, the motor is fixedly connected to one side of the mounting plate, and the output end of the motor is fixed to the bidirectional screw, the two screw nuts are both threadedly connected to the circumferential side of the bidirectional screw, and the two movable plates are respectively fixedly connected to the upper ends of the two screw nuts.

[0009] By adopting the above technical solution, the clamping mechanism can drive the movable plate, the mounting frame and the rotating wheel to move, and clamp the square steel pipe according to the size of the square steel pipe.

[0010] In a preferred example, the utility model can be further configured as follows: two limit rods are fixedly connected between the side walls of the rectangular groove, and the two screw nuts are slidably connected to the circumferential sides of the two limit rods.

[0011] By adopting the above technical solution, the limiting rod and the screw nut are slidably matched, which can improve the movement stability of the screw nut.

[0013] By adopting the above technical solution, the limiting mechanism can be adjusted and clamped according to the thickness of the square tube.

[0014] In a preferred example, the utility model can be further configured as follows: a plurality of anti-slip grooves are provided on the circumferential sides of the four upper limiting wheels, and a waste material groove is provided on the upper end of the processing box.

[0015] By adopting the above technical solution, the waste trough can collect welding residues.

[0016] In a preferred example, the utility model can be further configured as follows: a splash shield is fixedly connected to one side of the processing box, and an air outlet is installed on one side of the splash shield.

[0017] By adopting the above technical solution, the splash shield can prevent welding slag from splashing, and the air outlet can cool the welding position.
