Track plate body positioning and welding tool and welding process thereof

Abstract

The invention discloses a track plate body positioning and welding tool and a welding process thereof, and belongs to the technical field of track plate body positioning and welding; and through accurate positioning of two track plates, the welding precision of track plate bodies is improved, and the assembly and use requirements of the track plate bodies are met. The welding tool comprises two parts including a base and a positioning piece. The welding process realizes association of two parts of the track plate bodies through the positioning piece to guarantee related size requirements so asto realize positioning and welding of the track plate bodies. The precise positioning of the track plate bodies can be realized; the reliable support is provided for assembly of the track plate bodies; and the excellent foundation guarantee is provided for the performances of an action part of an armored car body.

Description

technical field [0001] The invention belongs to the technical field of positioning welding of armored car body track plates, and relates to a positioning welding tool for armored car body track plates. Background technique [0002] Armored car body The crawler body is a component of the entire track, and the track part is an important part of the vehicle's walking part. [0003] The track shoe body is formed by butt welding of two track shoes, requiring certain coaxiality and position requirements. See attached figure 1 . [0004] The original welding scheme is to place two track shoes on a (horizontal) platform, and align and fix them according to the symmetrical position of the center. Since there is no effective alignment and clamping device to ensure the coaxiality and position, there will be differences after welding. The position on the axis and the longitudinal direction is out of tolerance. [0005] The result is that the two track shoes are uneven and uneven in ...

Problems solved by technology

[0004] The original welding scheme is to place two track shoes on a (horizontal) platform, and align and fix them according to the symmetrical position of the center. Since there is no effective alignment and clamping device to ensure the coaxiality and position, there will be differences after welding. Axis and longitudinal position out of tolerance

[0005] The result is that the two track shoes are uneven and uneven in the width direction, which will make it difficult to assemble the whole track. After loading, it will affect the stability of the vehicle, and it will also cause a sharp increase in local pressure, resulting in a decrease in the stability of the vehicle. Partial acceleration fails, reducing vehicle reliability
