General type assembly welding and positioning device used for various side wall frameworks

Abstract

The invention discloses a general type assembly welding and positioning device used for various side wall frameworks, and relates to the technical field of railway vehicle side wall framework welding.The general type assembly welding and positioning device comprises a plurality of foundation T-shaped slot guide rails, a plurality of height adjustable foundation beds, a table board, four pressingmechanisms, a plurality of ball head mechanisms, a plurality of pivotal shafts, a plurality of upper positioning blocks, a plurality of lower positioning blocks, a plurality of cushion blocks and twothree-sided right-angled positioning blocks. The height adjustable foundation beds, the ball head mechanisms and the pivotal shafts are matched, so that the supporting end surface of the table board has different angles, and therefore, side wall frameworks of different structures can be supported; the height adjustable foundation beds are matched with the foundation T-shaped slot guide rails, so that production cost is reduced, and support for side wall frameworks of various structures can be safely and reliably realized; and the upper and lower positioning blocks are matched, so that quick positioning and assembly for the side wall frameworks of various structures is realized. The device is convenient in dismounting, is simple in operation, is strong in generality, reduces workload of anoperator, reduces the production cost, and improves production efficiency.

Description

technical field [0001] The invention relates to the technical field of rail passenger car side wall frame welding, in particular to a general welding positioning device for various side wall frames. Background technique [0002] At present, in the multi-project production process of the car body structure, due to the limitation of the production site and spot welding equipment, the side wall skeleton process of each project can only be produced in series. Such as Figure 1 to Figure 3 As shown, the side wall frame 11 is welded by two door frames 11-1, a skirt frame 11-2, a window frame 11-3 and a frame upper beam 11-4. Since the two door frames 11- 1 and the upper part of the window frame 11-3 are arc-shaped structures, and the arc angles at different compartment positions are slightly different, and the number of openings of the skirt panel frame 11-2 and the window frame 11-3 at different compartment positions and The positions of the openings are different, and the diffe...
