Description
Technical field
The utility model is related to rail traffic vehicles body construction, particularly a kind of side wall of stainless steel body for mass transit vehicles
Structure.
Background technology
Current stainless steel rail vehicle side wall covering is generally using horse leg formula overlap joint spot-welded structures, resistance electric welding connection side
Formula, step is exposed on the outside of car body or step is exposed on the outside of car body in body inner side pit, and this structure is applied to exempt from application
Car body, it is difficult to eliminate step or pit, it is unfavorable to car body pad pasting, influence car body it is attractive in appearance.In addition, using grafting between side wall skeleton
Formula structure, it is impossible to which regulation is not suitable for batch production, welding performance is bad.Sidewall window angle is the place that stress is easily concentrated, most of
Using 3 layers（Or even multilayer）Reinforcing plate resistance spot welding, first will wherein 2 layers spot welding, then with another laminate spot welding, solder joint arrangement by
Limit, may unsightly, during manufacture occur quick-fried situation, it is difficult to repair.
Utility model content
Technical problem to be solved in the utility model is, in view of the shortcomings of the prior art, providing a kind of surfacing, to be beneficial to
Vehicle surface mask, improves vehicle stainless steel car body sidewall structure attractive in appearance.
In order to solve the above technical problems, the technical solution adopted in the utility model is：A kind of stainless steel car body sidewall structure,
Side wall skeleton including side wall covering and on the inside of side wall covering, side wall skeleton includes being equipped with crossbeam and column, column
Groove, crossbeam is inserted in the groove of column, and the junction of crossbeam and column is connected by arc-welding, side wall covering by upper covering and
Lower covering is formed by the weldering of Laser Welding group.
Open up waist-shaped hole on the crossbeam, and the mounting hole of crossbeam is located at the junction of crossbeam and column.
Window frame is additionally provided with the stainless steel car body sidewall structure, window frame is enclosed to set by column and crossbeam to be formed, and window frame
Both sides set window frame to strengthen column, and window frame is strengthened column and is connected by resistance spot welding with upper and lower covering, and window frame is strengthened column and passed through
Two-ply is connected with side wall skeleton arc-welding.
The two ends bending that the window frame strengthens column forms arc.
The utility model side wall covering is attached by upper covering and lower covering by way of laser welding, laser soldering set
There is the characteristics of higher weld strength and less heat are inputted, the welding applied to stainless steel plate can largely reduce weldering
Deformation is connect, so as to effectively control and reduce the overall deformation extent of side wall, side wall covering overlap joint platform of the prior art is eliminated
Rank, realizes that side wall outer surface is smooth, beneficial to Vehicle surface mask, vehicle aesthetic property is improved, while the close of car body can be improved
Feng Xing, weld seam docking location is more flexible, without architectural limitation, can effectively utilize raw material.Plug-in type side wall skeleton is layed in
On side wall covering, it is connected by resistance spot welding with side wall covering.Side wall skeleton section is the crossbeam and column grafting arc of shape for hat
Weldering is formed, and crossbeam opens waist-shaped hole with longeron splicing position, and crossbeam is embedded in corresponding groove, can be by extruding waist-shaped hole to crossbeam
Width carries out fine tune, beneficial to grafting operating process, improves operating efficiency, while ensureing angle welding at the T junction of column
Gap is sufficiently small, it is ensured that welding quality.Also groove is opened up on the left and right longeron of window and plugs crossbeam formation window frame, window frame both sides are adopted
Strengthen column with integral type bending welding window frame, it is ensured that car body strength and rigidity, window frame are strengthened column and passed through with upper and lower covering
Two layers of sheet material carries out resistance spot welding connection, simplifies design and technical process, and solder joint arrangement is uniform, and weld indentation is smaller, improves
The aesthetic property of vehicle.

Embodiment
As Figure 1-Figure 5, the side wall covering of the utility model stainless steel car body sidewall structure is by upper covering 1 and lower covering
2 are formed by the weldering of Laser Welding group.Side wall skeleton 3 is formed by opening up the crossbeam 4 of waist-shaped hole 7 and the grafting of column 5 of recessing, crossbeam
The groove link position for opening up position just for crossbeam 4 and column 5 of 4 mounting hole 7, and the junction of crossbeam 4 and column 5 is logical
Cross arc-welding connection.Window frame is strengthened column 6 and is connected by resistance spot welding with upper covering 1 and lower covering 2.
