Problems solved by technology

[0006] In order to solve the special structure of the curves or curved surfaces of the four core components of the bird-wing-shaped side beam box frame structure on the existing structure, the clamping and positioning work before assembly and welding is difficult and complicated, and the production efficiency is low. The positioning and welding process of the axle hinge seat is time-consuming and laborious, requiring a lot of surveying, drawing, marking and post-welding repair work. Moreover, the welding posture of the axle hinge seat often deviates due to the deformation during welding and cooling, and the welding quality is difficult to be effectively controlled. To solve the technical problem, the present invention provides a pairing and positioning tool for the welding of side beams

Embodiment Construction

[0045] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0046] like Figure 7 to Figure 9 As shown, the paired positioning tooling for side beam formal welding of the present invention includes a foundation platform 2, two side beam end positioners 3, two axle hinge seat door arch positioners 4 and four side beam upper edge vertical To the compactor 5, each axle hinge seat arch positioner 4 and a corresponding side beam end positioner 3 together form a side beam end positioning device; the two side beam end positioning devices are fixed symmetrically at both ends of the base platform 2.

[0047] The basic platform 2 includes a platform plate, a positioning template 2-1 for the horizontal section of the lower cover plate, and four positioning template pressing blocks 2-2. The middle part is provided with the through hole 2-1-1 of the positioning model, and the horizontal pressing block of the positioning model pr...

Abstract

The invention relates to an assembly positioning tool for side beam dressing welding and belongs to the field of auxiliary clamping devices for welding assembly positioning of track vehicle bogie sidebeam devices. The assembly positioning tool includes a base platform, two side beam end positioners, two axle hinged support gate arch positioners and a plurality of side beam upper edge vertical squeezers. Each axle hinged support gate arch positioner and one corresponding side beam upper edge vertical squeezer jointly form a side beam end positioning device. The lower ends of the plurality of side beam upper edge vertical squeezers are fixedly connected to the middle portion of the base platform, and the two side beam end positioning devices are symmetrically fixedly connected to the two ends of the base platform. The assembly positioning tool for side beam dressing welding can completely omit mapping and scribing operation during the side beam assembly, and a component positioning modeis simple, convenient, accurate and reliable and can effectively restrain welding deformation at each position of a bird wing-shaped side beam, the repair work after the welding is reduced, and thusthe production efficiency and product quality can be greatly improved.

Description

technical field [0001] The invention belongs to the field of auxiliary clamping devices for welding group pair positioning of rail vehicle bogie side beam devices, and in particular relates to a group pair positioning tool for side beam normal assembly welding. Background technique [0002] Such as figure 1 and figure 2 As shown, the bird-wing-shaped side beam 1 on the rail passenger car bogie frame is a kind of bird-wing-shaped vertical plate 1-2 and a bird-wing-shaped vertical plate 1-3 with a central pin shaft and a bird-wing-shaped side beam upper cover. Plate 1-1, bird-wing-shaped side beam lower cover plate 1-4 and other structures are assembled and welded together to form a box-shaped structure. A vertical central pin 1-3-1 is provided in the middle part of the bird-wing-shaped vertical plate 1-3 with the center pin shaft, and the curved surface shape of the bird-wing-shaped side beam upper cover plate 1-1 and the bird-wing-shaped side beam The curved surface shap...
