Description

Technical Field

[0001] The utility model relates to the technical field of automobile manufacturing, in particular to a longitudinal beam assembly positioning and beam-joining system. Background Art

[0002] In the production process of heavy truck frames, the beam-joining system is used to position and assemble the inner and outer longitudinal beams transmitted from the warehouse, and transport the longitudinal beam assembly to the frame assembly line; according to different loads, the frame longitudinal beam assembly is generally a three-layer beam, double-layer beam, or single-layer beam structure; the three-layer beam and double-layer beam structure require precise positioning of the relative size between the inner and outer beams, and the single-layer beam generally has an inner reinforcement plate and a short U-shaped beam, which need to be assembled at the beam-joining station. Therefore, the beam-joining system needs to simultaneously meet the positioning of the multi-layer beam and the assembly of the inner reinforcement beam of the single-layer beam;

[0003] Traditionally, the inner and outer longitudinal beams are joined by bolts. However, when the longitudinal beams are manually assembled, the inner and outer beams cannot be hung accurately according to the assembly position, and the holes need to be moved multiple times, with one person hanging and one person installing the bolts. When assembling reinforcement plates on single-layer beam frames, there are no positioning points. One person holds the reinforcement plate in position by hand while another person assembles the bolts. When assembling long reinforcement plates, more people are required. The labor intensity is high, the efficiency is low, and the operation is inconvenient. Utility Model Content
