Example Embodiment

[0022] The present invention will be further described below in conjunction with the drawings.

[0023] According to the structural characteristics of the side-bearing air duct beam, the tooling of the present invention uses the three elements of "supporting, positioning and clamping" of the welding tooling and the principle of supporting, positioning and clamping the object at six points in space to enable the side-bearing air duct beam to be positioned Welding is carried out at the appropriate position to ensure that qualified products are manufactured. Such as figure 2 As shown, with the bracket 6 as the supporting reference, the side bolster assembly etc. are assembled to one place through it and the positioning seat 7 etc., and then the positioning and clamping devices are installed in the corresponding position of the upper plane of the positioning seat 7 Clamp the components of the side bearing air duct beam.

[0024] The bracket 6 is bent from a plate into channel steel, ...

Abstract

The invention discloses a welding-efficient tool for welding a side bearing air duct beam. The tool comprises brackets and positioning seats supported by the brackets; every mutually connected brackets and positioning seats are a group; the positioning seats are fixedly connected with the brackets; the brackets are fixed on a base; at least two groups of brackets and positioning seats are fixed on the base; and the upper surface of each positioning seat is a positioning surface and matched with the side bearing air duct beam. With the adoption of the tool, each weld joint of the side bearing air duct beam is positioned in an appropriate place, so that the weld joint quality is improved, the assembly precision is ensured, the deformation is controlled, the labor intensity is reduced, the processing efficiency is improved, and the tool is applicable to the welding work of the side bearing air duct beam.

Description

technical field [0001] The invention relates to the technical field of side bearing duct beam processing. Background technique [0002] The side bearing duct beam is an important part of the locomotive, its function is to connect the chassis and the center beam, and it is also an important part to connect the bogie. Such as figure 1 As shown, the side bearing air channel beam is composed of two side bearing beam assemblies, one beam assembly, two air channel beam assemblies, several channel steel and other components. After side bolsters, air duct beams, channel steel, etc. are welded into an integrated structure, they are integrally welded with the underframe. [0003] Practice has proved that the welds welded at positions with good accessibility have good shape and few process defects. With the platform at the present stage, the outdated method of using a crane to flip and weld the side bearing duct beam is difficult to ensure the accessibility of the weld position to b...
