Rapid coupling and positioning fixture for side vertical plates of bogie

Abstract

The invention discloses a rapid coupling and positioning fixture for side vertical plates of a bogie, belonging to the field of welding positioning assistant devices for the side vertical plates of the rail car bogie. The rapid coupling and positioning fixture comprises compression components, component connection shafts, hydraulic devices, adjustment crankshafts, banking pins, bases, self-opening-and-closing adjustment blocks, positioning support racks, limiting pins, support components and a substrate, wherein two compression components, one component connection shaft, one hydraulic device, two adjustment crankshafts, one banking pin, one base, one self-opening-and-closing adjustment block, one positioning support rack, one limiting pin and one support component jointly form one small-angle self-opening-and-closing clamping and positioning device. According to the rapid coupling and positioning fixture, by utilizing cooperative work of the multiple groups of small-angle self-opening-and-closing clamping and positioning devices, multiple side beam vertical plates can be precisely positioned synchronously, so that working efficiency and positioning precision of welding coupling operation are improved, and an inhibition effect of welding anti-deformation is realized.

Description

technical field [0001] The invention belongs to the field of welding and positioning auxiliary devices for side beam vertical plates of rail vehicle bogies, and in particular relates to a quick assembly and positioning tool for side vertical plates of a bogie. Background technique [0002] The frame and other mechanisms of rail cars use a large number of large parts with box-shaped cross-sections that are spliced ​​and welded by multiple plates. Under many specific process design conditions, the production sequence of some of these parts is to place them vertically first. The vertical plate is then welded to the upper and lower end faces of the vertical plate or the bottom plate to finally form the required box-shaped large component structure. [0003] Such as figure 1 and figure 2 As shown, the side beam on the train frame is a box-shaped structure formed by joint welding of two bird-wing-shaped vertical plates 12 and other upper and lower cover plates. According to the...

Problems solved by technology

[0006] In order to solve the existing special operation process of first positioning the vertical vertical plate, multiple sets of horizontal or vertical clamps used in pairs, horizontal or vertical screw positioning tools and other auxiliary positioning tools are usually used in conjunction with the use, and the number of layouts is large, The positioning and unlocking efficiency is low, the operation is cumbersome, and it is not conducive to classified inventory management; and the vertical plate positioning method of prefabricated various slot tooling with different widths is poor in versatility, which is not conducive to saving production costs. The invention provides a bogie side Rapid assembly and positioning tooling for vertical panels
