[0001] The utility model belongs to the technical field of vehicle body folding auxiliary installation, and in particular relates to a folding positioning tool for a side door. Background Art

[0002] Railway freight cars are vehicles used for rail freight transport. The main types include open wagons, covered wagons, and flatbed wagons. Each type has its own unique characteristics and uses. For example, open wagons are suitable for transporting large equipment and bulk cargo, covered wagons are suitable for transporting goods that need to be protected from moisture and sunlight, and flatbed wagons are convenient for loading and unloading large and heavy cargo. The main feature of open wagons is that they have no roof and have side panels on all four sides, two of which can be opened to facilitate unloading.

[0026] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0027] Please also refer to Figure 1 and Figure 2 The side-opening door hinge positioning tool provided by the present invention is now described. The side-opening door hinge positioning tool includes a support rod 10 and a hinge positioning seat 20. The support rod 10 and the hinge positioning seat 20 are provided in pairs. The two hinge positioning seats 20 are spaced apart on the support rod 10, and each hinge positioning seat 20 has a hinge portion arranged parallel to the central axis of the support rod 10.

[0028] Among them, the combination of the support rod 10 and the positioning hinge seat 20 is used to be clamped on the car body and the side door in turn, by simulating the position of the hinge seat on the open car body, and through the hinge part, the hinge on the side door is positioned and welded.

[0029] Compared to the prior art, the side door hinge positioning fixture provided in this embodiment incorporates a support rod 10 that secures the position of two hinge positioning seats 20. These two hinge positioning seats 20 mimic the position of hinge seats on a gondola body and can be sequentially mounted on the carriage and then on the side door to perform position welding on the hinges. This prevents deviation of the side door hinges during assembly, simplifies welding, and offers high mass versatility, excellent adaptability, and enhanced practicality.

[0030] In some embodiments, the positioning folding seat 20 can be used as follows Figure 1 、 Figure 2 The structure shown. Figure 1 、 Figure 2Each positioning folding seat 20 includes a positioning plate 21 and a partition 22. Two positioning plates 21 are provided, and are fixed to the support rod 10 in parallel and spaced apart along the extension direction of the support rod 10. Each positioning plate 21 has a through hole for the support rod 10 to pass through. Multiple partitions 22 are provided, and each partition 22 is evenly distributed between the two positioning plates 21 and connected to the two positioning plates 21 to support and secure the two positioning plates 21.

[0031] The two positioning plates 21 can be supported and fixed by vertically setting a partition 22 between them. The positioning plates 21 can allow the support rod 10 to pass through the through holes thereon. When multiple partitions 22 are fixedly installed, they avoid the through holes to avoid interference when installing the side door hinge.

[0032] It should be noted that the partition plate 22 and the positioning plate 21 can be integrally welded. Integrated welding is an advanced manufacturing process that joins multiple components or materials together in a single welding process to form a single, integrated structure. This process can significantly improve production efficiency, reduce costs, and enhance product quality and performance. Integrated welding is a well-known technique and will not be elaborated upon here.
