Description

Technical Field

[0001] The utility model relates to the technical field of butt welding devices, in particular to a butt welding device for square tube argon arc welding. Background Art

[0002] When using an argon arc welding device to weld two sets of square tubes, a docking device is required. The docking device can accurately dock the two sets of square tubes so that the connecting ends of the two sets of square tubes can be accurately docked to prevent deviation during docking.

[0003] The existing docking device includes a side plate installed on the top of the docking platform, and a clamping piece is installed on the inner wall of the side plate. The clamping pieces on both sides can respectively clamp and fix the ends of the two sets of square tubes that are far away from each other. Then, by bringing the side plates on both sides closer to each other, the ends of the square tubes clamped on both sides that are close to each other are accurately docked, which facilitates the welding operation of the connection ends of the two sets of square tubes.

[0004] In actual use, since the length of the two sets of square tubes after butt-joining is relatively long, and although the butt ends of the two sets of square tubes are in a clamped and supported state, the two sets of square tubes are in a horizontal state after butt-joining, but during welding, the welding head will exert a certain force on the butt ends of the two sets of square tubes. In the absence of support for the butt ends of the two sets of square tubes, it is easy for the butt ends of the two sets of square tubes to tilt downward, thereby affecting the quality of the butt welding of the two sets of square tubes. In view of the shortcomings of the existing technology, we propose a butt joint device for square tube argon arc welding to solve the above problems. Utility Model Content
