Embodiment Construction
[0023] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0024] Such as Figure 4 to Figure 9 As shown, the general-purpose assembly welding positioning device for various side wall frameworks of the present invention includes: multiple base T-shaped groove guide rails 1, multiple height-adjustable bases 2, table tops 3, four pressing mechanisms 4, A plurality of ball head mechanisms 5 , a plurality of pivots 6 , four upper positioning blocks 7 , two lower positioning blocks 8 , a plurality of spacers 9 and two three-sided right-angled positioning blocks 10 . The T-shaped bolt can slide in the T-shaped groove guide rail, and can be locked and positioned at the required fixed position by the nut.
[0025] A plurality of base T-slot guide rails 1 are fixed on the ground in parallel, the bottoms of multiple height-adjustable bases 2 are fixedly connected to the base T-slot guide rails 1 through T-shaped bolts, and th...

The general-purpose assembly welding positioning device for various side wall frames relates to the field of railway car side wall frame welding technology, which includes multiple base T-slot guide rails, multiple height-adjustable bases, table tops, and four pressing mechanisms , multiple ball head mechanisms, multiple pivots, multiple upper positioning blocks, multiple lower positioning blocks, multiple pads and two three-sided right-angle positioning blocks. Through the cooperation of the height-adjustable base, the ball head mechanism and the pivot, the present invention realizes that the supporting end faces of the table have different angles, and can support a plurality of side wall skeletons with different structures; through the height-adjustable base and the base T-shaped The cooperation of the groove guide rail not only reduces the production cost, but also can safely and reliably support the side wall framework of various structures; through the cooperation of the upper and lower positioning blocks, the rapid positioning and pairing of the side wall framework of various structures can be realized . The device is convenient to assemble and disassemble, simple to operate, and has strong versatility, which reduces the workload of the operator, reduces the production cost, and improves the 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...
