Description

Technical Field

[0001] The invention relates to the technical field of manufacturing equipment, in particular to a large side beam composed assembled tire. Background Art

[0002] A certain type of flat car is different from a traditional single-layer flat car in terms of car body structure. The car body has no center beam behind the pillow, and is a curved side wall load-bearing structure. The side beam assembly is nearly 16 meters long and is welded together by a first lower side beam 91, a second lower side beam 92, a web 93, an upper side beam 94, a small side column 95, a large side column 96, a middle side column 97, an end plate 98, and a side beam 99. The first lower side beam 91 is a rounded bent plate, the second lower side beam 92 is an L-shaped bent plate, the web 93 is a large plate with folded edges, the upper side beam 94 is a square steel structure, and the small side column 95 is a channel steel structure with grooves. The web 93 is assembled on the outside of the side pillar and is streamlined. During the manufacturing process, the assembly dimension control of the side beam component is the key to the vehicle body assembly. Therefore, it is particularly important to control the side beam component as a key process. However, the existing tooling equipment is difficult to meet the batch operation of the side beam component assembly. Batches of assembly parts are piled up on site, and simple tooling causes hidden dangers in the quality of vehicle body assembly and poor production process flow.

[0003] In the early stage of production, the side beam components were generally made on the platform, and the side beam components were assembled by measuring and positioning with a backrest and a tape measure. The assembly sequence is as follows: web 93 → first lower side beam 91 → second lower side beam 92 → end plate 98 → upper side beam 94 → large side column 96 → side beam 99 → small side column 95, middle side column 97. However, the side beam components are mainly welded by plates, bent parts, profiles, etc. of different thicknesses. Due to the curved design, long length, large lateral area of ​​the side beam components, and the influence of blanking deformation and bending accuracy, it is difficult to keep the assembly accuracy of the side beam components assembled on the platform consistent with the design. In addition, due to the curved structure, it is difficult to detect and correct it. There is a lack of large-scale clamping devices, and the welding deformation is large. It is difficult to control the size of the side beam components after assembly and welding. Summary of the invention

[0004] In order to overcome the above-mentioned shortcomings of the prior art, the present invention provides a large-sized side beam assembly tire.

[0011] By setting up two sets of pressing devices and two sets of automatic welding units, the welding positions of the two welds can be pressed and automatically welded at the same time. The two gantries move alternately to complete the welding along the entire length, thereby improving the welding efficiency and quality.

[0012] According to another embodiment of the present invention, further including, the positioning support assembly comprises a plurality of first bases and second bases arranged in parallel and spaced apart along the width direction of the platform, the first base being provided with a first supporting surface, a second supporting surface, a first backrest and a second backrest, the second base being provided with a third supporting surface, a fourth supporting surface, a fifth supporting surface, a third backrest, a fourth backrest and a fifth backrest.
