Abstract

The invention provides a sky train body welding fixture and a welding method thereof. The sky train body welding fixture comprises a foundation fixture, a cross beam, a boundary beam clamping device,a boundary beam type block and an assistant support rod for assembly of a train body. The cross beam is installed across the foundation fixture. The boundary beam clamping device is positioned at twoends of the cross beam. The boundary beam type block is connected with the boundary beam clamping device. The foundation fixture comprises a longitudinal I beam, a horizontal I beam, a bottom plate, an adjusting bolt, a support rod component and a longitudinal reinforcing rib. The boundary beam clamping device comprises a cantilever mechanism, an upright structure and a bottom base. The upright structure is vertically installed on the bottom base. The cantilever mechanism is connected with the upright structure. The provided welding fixture has the characteristics of simple structure, novel design, convenient operation, and strong universality and is capable of effectively controlling the welding deformation, realizing the double functions of positioning and welding deformation resistance,guaranteeing the quality, reducing the labor intensity and improving the production efficiency.

Description

technical field [0001] The invention relates to the technical field of aerial rail trains, in particular to a welding tool for an aerial rail train body and a welding method thereof. Background technique [0002] The sky rail train is a kind of rail vehicle suspended on the sky rail, and it is a new type of public transportation with light weight, medium speed and medium capacity. Compared with the urban rail subway, the biggest difference is that the suspension method is different, and the sky rail train is suspended from the top cover. Compared with traditional subway vehicles, the structure of the top cover is quite different, making it more difficult to manufacture. The main structure of the aerial rail train body is generally made of aluminum alloy, which has many advantages such as light weight, corrosion resistance, easy processing and high strength. However, at present, when aluminum alloy is welded, the temperature is high, and the section direction of the profile...
