Assembling and positioning device for rivet welding manufacturing of building steel structure

The invention relates to the technical field of steel structure machining, in particular to an assembling and positioning device for building steel structure rivet welding manufacturing, which comprises a base, limiting frames are symmetrically mounted on a top plate of the base, a plurality of mounting grooves are respectively formed in two ends of the top plate of the base, and conveying assemblies are respectively arranged in the plurality of mounting grooves. The conveying assembly comprises rotating shafts and supporting rollers, the rotating shafts are rotatably mounted on the two side faces of the inner wall of the mounting groove, and limiting frames, mounting bases, threaded rods, connecting blocks and limiting plates are arranged and used in cooperation, so that after the two steel structure bodies needing to be welded are placed on the base and located in the corresponding limiting frames correspondingly, the two steel structure bodies need to be welded; the limiting plate can be moved by rotating
