Automatic welding device of box-type steel member

Abstract

The invention discloses an automatic welding device of a box-type steel member. The automatic welding device of the box-type steel member is characterized in that the upper end of a support is connected with the lower end of a cantilever seat in a rotating mode; a movable seat arranged in the middle of the support is longitudinally connected with a welding gun; an outer side support of the welding gun is transversely connected with a walking wheel; an inner side support of the welding gun is transversely connected with a soldering flux stop plate; the support below the soldering flux stop plate is longitudinally connected with a guide wheel; a rotating center of the walking wheel is perpendicular to the center of the welding gun; a rotating center of the guide wheel is parallel to the center of the welding gun. The walking wheel and the guide wheel on the support are driven to correspondingly move on the top face and side faces of the box-type steel member by controlling over the welding device, and meanwhile welding bars in a middle hole of the welding gun are driven to automatically perform even and dense welding along a welding seam in the length direction of the box-type steel member. Soldering flux fluid generated by welding can be blocked stopped by the soldering flux stop plate and be prevented from flowing outwards. The automatic welding device of the box-type steel member obviously improves the working efficiency and machining quality of welding and effectively lowers production and machining costs.

Description

technical field [0001] The invention relates to welding processing equipment; in particular to an automatic welding device for box-type steel components. Background technique [0002] The processing equipment for welding large and medium-sized steel components in the prior art, such as gantry welding equipment, can only automatically weld the right-angle welds on the inner surface of the "I"-shaped steel components, but the outer surface of the box-shaped steel components The welding seam cannot be automatically welded due to the limitation of the welding equipment. In production operations, people usually can only weld by hand. There are deficiencies: one is that the efficiency of manual welding is low. The second is that different skilled workers have a large gap in the quality of manual welding. During work, sometimes the welds on the outer surface of the box-type steel members need to be reworked and re-welded due to quality problems such as pores and slag inclusions d...

There are deficiencies: First, the efficiency of manual welding is low

The second is that different skilled workers have a large gap in the quality of manual welding. During work, sometimes the welds on the outer surface of the box-type steel members need to be reworked and re-welded due to quality problems such as pores and slag inclusions during welding. Increased production and processing costs
