An aluminum alloy passenger car body framework comprises an upper framework structure assembly and a lower framework structure assembly; the upper framework structure assembly is fixedly connected into a whole by aluminum alloy rod pieces, an upper connecting cross beam is arranged at the bottom of the upper framework structure assembly, and a door front upper upright post and a door rear lower upright post are arranged at a right door opening; the lower framework structure assembly is fixedly connected into a whole by aluminum alloy rod pieces, a lower connecting beam is arranged at the top of the lower framework structure assembly, and a front lower upright post and a rear lower upright post of the door are arranged at the right doorway; an upper connecting beam in the upper framework structure assembly is in threaded connection with a lower connecting beam in the lower framework structure assembly; the upper door front upright post in the upper framework structure assembly is welded with the lower door front upright post in the lower framework structure assembly; and the upper upright post behind the door in the upper framework structure assembly is welded with the lower upright post behind the door in the lower framework structure assembly.
Furthermore, the mounting hole for the screw connection of the upper connecting beam and the lower connecting beam is formed in the upper surface of the upper connecting beam.
Furthermore, the lower surface of the upper connecting beam is provided with a through hole which corresponds to the upper connecting beam in a threaded manner and is used for bolt connection.
Furthermore, the upper surface of the lower connecting beam is provided with a riveting nut corresponding to the upper connecting beam in a threaded manner.
Further, the upper connecting beam is screwed with a riveting nut arranged on the lower connecting beam through a bolt.
Further, the door front upper upright post and the door front lower upright post are welded together through Tig welding; the upper post and the lower post are welded together by Tig welding.
The utility model has the advantages of it is following:
1. the passenger car body framework structure is divided into an upper framework structure and a lower framework structure, and compared with the production process of six-piece sub-assemblies of the traditional passenger car framework, the number of the sub-assembly production and manufacturing clamps can be reduced, and the production cost is reduced.
2. The bus body framework structure is formed by splicing an upper framework structure and a lower framework structure, and compared with the splicing process of the existing bus framework six-piece subassembly, the splicing efficiency of the whole bus can be improved.
3. The assembling process of the six-piece sub-assembly of the passenger car frame needs the left side and the right side to enclose the tool clamp, the bottom frame tool clamp and the top cover and the front and back to enclose the tool clamp. Compared with the traditional six-piece framework assembling process, the number of the tool fixtures is reduced, and the production cost is saved.
4. The upper connecting beam and the lower connecting beam are connected through the bolts to realize the assembly of the whole vehicle, the height of the bolt connection position is appropriate, operators do not need to work high above the ground, and the production efficiency is improved. When six large piece subassemblies of passenger train skeleton are assembled production at present, when top cap and side wall and front and back enclose the amalgamation, the workman need carry out high altitude construction, and production efficiency is low.
5. The upper framework structure and the lower framework structure of the passenger car body framework structure are respectively two independent closed structures, and the passenger car body framework structure is easy to produce and manufacture.
