Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of profile steel welding fixture, more particularly, the utility model relates to profile steel auxiliary butt welding device. BACKGROUND

[0002] The profile steel needs to be welded for many reasons. Firstly, when building large structures such as bridges and high-rise building frames, a single profile steel cannot meet the demand, and welding can connect multiple profile steels to achieve the required length and shape. Secondly, to change the structure form to adapt to specific layout and mechanical properties, such as building different frame structures, welding is required to form a specific combination. Thirdly, it can be used to repair and reinforce locally damaged or defective profile steels to restore their performance. Fourthly, it can improve material utilization and reduce waste by splicing remaining short materials.

[0003] After searching, the patent with publication number CN215091602U discloses a welding device for profile steel structure. The welding device is used to place the butt joint end of two profile steels on two movable plates, then start the clamping motor to drive the adjusting rod to rotate, and then move the movable baffle towards the fixed baffle to clamp and fix the profile steel. Then control the two moving devices to move towards each other to butt joint the two profile steels together, then start the telescopic rod to move down to make the welding device clamp the electrode in contact with the butt joint seam of the two profile steels.

[0004] However, the above-mentioned device has the following defects: the above-mentioned device can fix the profile steel through clamping to facilitate subsequent welding work, but the clamping device of the device can only ensure welding on one face. When one-turn welding of the profile steel is needed, the profile steel must be taken out for turning operation.
