The invention provides a positioning support device used for vehicle body assembling of a railway vehicle. The positioning support device comprises an extensible rod, detachable clamping pieces and connecting pieces. One end of the extensible rod is connected with the detachable clamping pieces through the connecting pieces; the other end of the extensible rod is used for supporting a side wall or an end wall of the railway vehicle, and the extensible rod can extend along the axis; and the detachable clamping pieces are used for being detachably clamped inside a dovetail groove of a corrugated plate of the railway vehicle. According to the positioning support device used for the vehicle body assembling of the railway vehicle, the detachable clamping pieces connected with the extensible rod through the connecting pieces are used so that the supporting of the extensible rod to the side wall can be achieved conveniently after the detachable clamping pieces are directly mounted and tightly locked in the dovetail groove during the mounting process; in the dismounting process, only unlocking is required for taking out the detachable clamping pieces from the dovetail groove; the corrugated plate is not prone to damage in the whole mounting and dismounting processes; and at the same time, welding dust and noise are not prone to occurring, and the quality of the working environment is improved.
Description
technical field [0001] The invention relates to a positioning support device for rail vehicle body assembly, which belongs to the technical field of rail vehicle manufacturing. Background technique [0002] During the manufacturing and assembly process of the rail vehicle body, it is necessary to assemble end walls and side walls on the chassis. In the assembly process, in order to adjust the inclination of the end wall and side wall, it is necessary to use a positioning support device for positioning and support. [0003] The existing positioning support device includes: a first telescopic rod and a second telescopic rod, the first telescopic rod and the second telescopic rod are connected by a rotating handle, and the connecting length of the first telescopic rod and the second telescopic rod can be adjusted by turning the rotating handle , and then adjust the total length of the positioning support device to adjust the inclination of the end wall or side wall.
