Abstract

The invention provides a welding tool and a welding method applied to a body skeleton of a railway vehicle. The welding tool comprises a supporting frame, longitudinal beams, cross beams and holding devices. The longitudinal beams, parallel to one another, are arranged on the supporting frame. A plurality of mounting gaps are formed on the longitudinal beams in the length direction. The cross beams span the longitudinal beams, and are arranged on the correspondingly mounting gaps. The holding devices are arranged on each cross beam. The generality of the welding tool applied to the body skeleton of the railway vehicle is improved, and the welding quality of the body skeleton is improved.

Description

technical field [0001] The invention relates to a rail vehicle, in particular to a welding tool and a welding method applied to the frame of a rail vehicle body. Background technique [0002] The welding of the rail vehicle body is one of the main processes in the manufacture of the rail vehicle body. In the past, the welding device of the project used a profiling design, that is, the positioning surface of the welding tool was designed to imitate the cross-sectional shape of the car body to realize its positioning and clamping. However, due to the variety of rail vehicle body structures and shapes, the welding tooling needs to adopt special welding tooling for different car body designs, resulting in many welding tools and poor versatility of welding tools; moreover, the skeleton often adopts welding Manufactured by advanced technology, the heat input is large, and it is easy to deform after welding and affect the quality of the product. Contents of the invention [0003...
