A frame flexible assembly and welding tool

Abstract

The invention discloses a flexible assembling and welding tool for frames. The flexible assembling and welding tool comprises a platform, side beam compressing devices (2), cross beam positioning devices (3) and cross beam jacking devices (4), wherein the side beam compressing devices (2), the cross beam positioning devices (3) and the cross beam jacking devices (4) are arranged on the platform. The platform (1) is provided with first sliding grooves (11), and the side beam compressing devices (2) are arranged in the first sliding grooves (11) correspondingly through connecting pieces. Second sliding grooves (12) are formed in the middle portion of the platform (1), and the cross beam positioning devices (3) are arranged in the second sliding grooves (12) correspondingly. The cross beam jacking devices (4) are arranged between the cross beam positioning devices (3) side by side in the Y direction. The assembling and welding tool has extremely high universality and applicability; and when the tool is used for assembling and welding truck frames of different types, it is not required to change the tool, only appropriate adjustment is needed, the product preparation period is short, the product exchanging efficiency is high, the output capacity of a workshop of unit area will not be affected, and too large pressure will not be brought to the workshop for storing the tool.

Description

Technical field [0001] The invention relates to the technical field of frame assembly processing of rail vehicles, and particularly relates to a processing tool for positioning and tightening the frame during assembly and welding of the frame during the production process of the rail vehicle. Background technique [0002] The bogie frame of rail vehicles is generally welded into an H-shaped box structure by two side beams, two cross beams and two longitudinal beams. The side beams are welded by steel plates into a concave U-shaped structure, and the side beams are welded with rotating arms. Positioning seat, primary vertical shock absorber seat, primary spring positioning seat, secondary air spring positioning seat, anti-rolling torsion rod seat, anti-snake shock absorber, bogie hoisting hanger, brake hanger, etc. , The beam is welded with traction rod seat, gear box hanger, traction motor hanger hanger, etc. [0003] At present, there are more and more varieties of subway and EMU...

AI Technical Summary

Problems solved by technology

[0003] At present, there are more and more varieties of subway and EMU products, forming a series of products such as EMU, 80 subway and A-type subway. The structure of each type of product is similar, but there are small differences. Versatility, applicability) are poor, in the case of slight changes in product structure, tooling needs to be changed, the product preparation cycle is long, and the efficiency of production change is low, which affects the output rate of the plant per unit area

[0004] And with more and more product types and structural differentiation, more and more tooling is required on site, and the pressure of tooling storage on the warehouse is increasing
