Embodiment Construction

[0014] Such as figure 1 As shown in the figure, after the chassis skeleton is prefabricated, it is directly sent to the chassis assembly station for suspension, bridge and tire assembly. In order to avoid heavy deformation, the engine, gearbox and other chassis components are not assembled here. Then, the five prefabricated car body skeletons and the assembled underframe are welded together at the hexahedron assembly welding station described in prior art 1. Afterwards, operations such as shaping, outer skinning, and painting can be carried out according to the flow described in the existing process 1. Finally, the engine, gearbox, steering system, braking system and other chassis parts are scattered on the vehicle assembly line for vehicle assembly.

[0015] The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention. Any minor modifications, equivalent replacements and improvements made to the above embodiments acc...

Abstract

The invention discloses a skeleton assembly process of a full-loading passenger car, which is characterized by comprising: after prefabricating the chassis skeleton, directly assembling a suspension rack, a bridge and tires, then welding and merging the prefabricated five skeletons of the car body with the assembled suspension rack, bridge and tires; and assembling the whole car and the chassis accessories via welded seam polishing, skeleton calibration, external covering and painting. Compared with the existing skeleton assembly process of the full-loading passenger car, the assembly process can be matched with the existing work position procedures without increasing apparatus investment in the prior art; and the difficulty in assembling the suspension and the bridge due to a small operation space in the prior art is reduced, the deformation of the chassis caused by non-uniform stress can be avoided, the precision of the sizes of the skeleton parts can be ensured, the assembly cost is lowered and the assembly efficiency the improved.

Description

technical field [0001] The invention relates to a general assembly process of a full load-bearing automobile, in particular to a general assembly process of a full load-bearing highway passenger car skeleton. Background technique [0002] At present, the frame structure of domestic passenger cars is dominated by semi-load-bearing frame structures, and full-load frame structures are the development trend. In addition to new construction, the workshops and workstations of the bus factory are mostly designed according to the semi-load-bearing skeleton structure. How to make the existing semi-load-bearing factory buildings and work stations suitable for the production of full-load-bearing skeleton structure buses, or transform the existing full-load-bearing factory buildings and work stations to improve their overall assembly efficiency is a problem that some bus manufacturers need to solve . [0003] At present, there are two general assembly processes for full load-bearing b...
