DETAILED DESCRIPTION

[0045] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

Conventional H-shaped steel needs to be spot welded first and then large-area welded. Therefore, after the H-shaped steel is spot welded, it is in an upright position on the surface of the conveying device 3 to prevent the spot welding structures on both sides from detaching; and after the material receiving device 1 receives the H-shaped steel, it needs to be flipped to a flat position to perform large-area reinforcement welding on the spot welding structures on its sides. There is a welding work position between the material receiving device 1 and the welding mechanism 2. The material receiving device 1 is used to ensure that the welding is completed at the work position after the H-shaped steel is flipped to a flat position. The H-beam is precisely positioned during the entire welding process to ensure its stability while increasing production and processing efficiency.

The first cylinder 151 is connected to one end of the first tilt arm 15, and the second cylinder 152 is connected to one end of the second tilt arm 16.
