The crossbeam part and the vertical column part are in a mutual lap joint to form the frame of the side wall structure, and then the side wall board is paved.
Description
Technical Field
The utility model relates to a rail vehicle's automobile body overlap joint formula side wall structure specifically adopts laser welding process to implement the overlap joint connection of crossbeam, stand to the side wall of stainless steel automobile body, belongs to the machine-building field.
Background
In order to meet and improve the requirements of installation and appearance design of a vehicle body module structure, a high-quality manufacturing technology which considers both vehicle safety and attractive appearance is generally adopted in the conventional domestic rail vehicles such as motor train units, subways, urban light rails and the like.
At present, the vehicle body of the railway vehicle is generally processed by adopting a welding mode of mainly spot welding and secondarily plug welding or arc welding, spot welding indentations can be remained on an outer wall plate in the welding mode, the indentations can not be completely eliminated, and unevenness of the inner surface and the outer surface of a side wall is directly caused to influence the attractiveness of the whole vehicle body.
The present application is made in view of this feature.
SUMMERY OF THE UTILITY MODEL
Automobile body overlap joint formula side wall structure, its design aim at solve the problem that above-mentioned prior art exists and adopt overlap joint formula frame construction, lay and carry out laser welding again behind the frame construction behind the overlap joint at the side wall board to higher welding strength reduces heat input volume, thereby controls effectively and reduces the holistic deformation degree of side wall.
Another design objective is, optimize the weight of overlap joint formula side wall structure, and bulk strength and security are higher, and easily dismantle, change a stand.
In order to achieve the above design objective, the car body overlap joint type side wall structure mainly comprises:
the door comprises a door upright post, a door upright post reinforcing post, a connecting plate, a beam part, an upright post part and a side wall plate which are connected with each other. Compared with the prior art, the door upright post is a groove-shaped section profile with unequal wing surfaces,
the window is arranged around the side wall, the upright post part comprises upright posts, window side upright posts, window upper upright posts and window lower upright posts, and the beam part comprises an upper side beam, a window upper beam, a window side beam, a window lower beam and a lower beam;
the beam part and the column part are mutually overlapped to form a side wall frame, and the overlapped part is connected by laser welding.
According to the characteristics of the basic scheme, the beam part and the column part are mutually overlapped to form a frame of a side wall structure, and then the side wall plate is paved.
Above-mentioned side wall frame construction is comparatively simple, but bulk strength is higher, easily control and improve the holistic pleasing to the eye emergence in order to avoid the spot welding indentation of side wall outward appearance.
In order to further improve the stability and the safety performance of the side wall structure frame, the improvement measures that the beam part and the column part are both provided with a section profile structure bent into a hat shape are adopted.
The deformation-resistant measure for side wall welding is that the side wall plate, the cross beam part and the upright post part after lap joint adopt a laser welding structure from the inner side of the side wall structure.
The side wall structure adopts laser welding with high welding strength and small heat input, and is easy to reduce deformation and improve the appearance of the whole side wall.
To sum up, the utility model discloses car body overlap joint formula side wall structure has the advantage be:
1. the lap joint type frame structure is adopted and laser welding is used for assisting, heat input quantity is reduced through high welding strength, and therefore the integral deformation degree of the side wall is effectively controlled and reduced.
2. The side wall structure has the advantages of light weight, high overall strength and high safety, and is easy to disassemble and replace the door stand column.
