The rear of one of the columns is provided with a vertical guide rail and a sliding seat that can be raised and lowered along the vertical guide rail. Above the vertical guide rail A motor connected with a screw mechanism is provided, and the sliding seat is driven vertically by the motor through the screw mechanism. Welding torches located on both sides of the two C-shaped steels are installed on the sliding seat, and the welding torches can be aimed at the weld seams of the two C-shaped steels for welding.

A horizontal guide rail is installed on the sliding seat, and a welding torch seat capable of moving horizontally is installed on the horizontal guide rail. The welding torch is placed on the welding torch seat, and the welding torch can be positioned on different positions of the horizontal guide rail through the welding torch seat.

There is a crank arm connected by a hinge shaft on the welding torch seat, and the welding torch is installed on the crank arm and can change the angle of welding by adjusting the angle of the crank arm.

The upper part of the welding torch is provided with a shading plate capable of blocking the outside and top of the welding torch, and the shading plate is fixedly installed on the sliding seat.

The pressing mechanism includes a cylinder-driven and horizontally telescopic pressing block installed on one side of a column and a positioning module installed on the other column.

After adopting the above-mentioned structure, due to the welding torch that can be raised and lowered on the vertical guide rail and the pressing mechanism for pressing the end faces of the two C-shaped steels, it can be directly positioned reliably by the pressing mechanism during the welding process. The welding torch can be directly aimed at the weld seam of two C-shaped steels for welding. At the same time, due to the horizontal guide rail installed on the sliding seat, the welding torch can also be positioned on different positions of the horizontal guide rail through the welding torch seat, so that the welding position can be effectively and precisely Adjustment, its positioning is reliable during the welding process, the positioning stability is good, no displacement will occur, the welding accuracy is guaranteed, and its high degree of automation greatly improves the welding efficiency.
