The invention discloses a tooling system for assembly of a train body of a rail train and auxiliary equipment. A installation structure of an installation tooling is arranged on the auxiliary equipment; the free ends of a first main body and a second main body of the auxiliary equipment can be correspondingly opened to form an opening; after the auxiliary equipment is arranged at the proper location from the side surface of a support structure, the free ends of the first main body and the second main body are correspondingly approached, so that the first main body and the second main body arein contact with the corresponding outer wall of the support structure and are clamped and positioned; finally, the first main body and the second main body are locked at the position by a locking part, so as to realize the positioning of the auxiliary equipment and the support structure. The tooling system has the advantages that under the cooperation function of the first main body as well as thesecond main body and the outer wall of the support structure, the processing of any structure on the support structure is not required; the strength and rigidity in use of the support structure are improved, and the assembly efficiency of the train body is improved; the flexibility in use of the assembly tooling is greatly improved in the assembly process of the train body.
Description
technical field [0001] The invention relates to the technical field of rail train body assembly, in particular to a tooling system and auxiliary equipment for rail train body assembly. Background technique [0002] The assembly of the rail train body usually adopts the reverse assembly process, that is, the assembly support platform is firstly set up. The assembly support platform in the prior art is mainly assembled by a plurality of beams to form a frame body. The press-fitting tool is used to position the side wall panels. [0003] At present, the side wall panels and beams are mainly positioned by the pressing method of the tooling. Since the upper space of the welding tooling is completely occupied, only the two sides of the tooling can be connected with the overall pressing tooling. In the prior art, bolts are used to fix and connect the adjusting pressing member to the crossbeam, which requires machining bolt connection holes on the crossbeam. Usually, according to ...
