Technical Field

[0001] The utility model relates to the field of welding support tools, in particular to a welding support tool for a rear sill. Background Art

[0002] The rear sill of Dongfeng Honda - Lingxi L is as Figure 2 shown. There is a rear sill lock groove on the rear sill, and a lock cover plate is installed at the rear sill lock groove part.

[0003] Sound - absorbing cotton is welded to the rear sill body to match the rear door trim. During the production and assembly process, due to the parts being of irregular shapes, it is inconvenient for workers to operate during the welding of the sound - absorbing cotton, and it cannot be guaranteed that the welding process of the sound - absorbing cotton will not cause problems such as part deformation.

[0004] Therefore, it is necessary to provide a welding support tool for the rear sill to solve the above - mentioned technical problems. Summary of the Utility Model

[0005] To solve the above - mentioned technical problems, the utility model provides a welding support tool for a rear sill.

[0006] A welding support tool for a rear sill provided by the utility model includes a base. A plurality of profiling seats for supporting the rear sill are fixed on the top of the base. A profiling surface matching the surface of the profiling seat is provided on the top of the profiling seat. A rear sill lock groove support seat is fixed on the top of the base. A profiling part matching the rear sill lock groove is provided on the top of the rear sill lock groove support seat, and a positioning post for limiting the lock cover plate is fixed on the profiling part.

[0007] Preferably, the profiling seats are arranged in parallel.

[0008] Preferably, after the rear sill is placed on this support tool, the part of the rear sill where the sound - absorbing cotton needs to be installed is in an inclined state.

[0009] Preferably, when the rear sill is placed on this support tool for welding and fixing the sound - absorbing cotton, the welding part of the sound - absorbing cotton is arranged opposite to the profiling seat.

[0010] Preferably, after the rear sill is placed on this support tool, the end of the rear sill is flush with the profiling seats at the end of the base.

[0011] Compared with the related technologies, the utility model provides the following beneficial effects: The tooling provides stable support for the rear sill through the profiling seat and the profiling surface, ensuring that it will not shake or shift during the welding operation, thereby improving the welding quality and efficiency. The welding part is facing the profiling seat, making the welding operation more accurate, reducing the possibility of welding deviation, and ensuring the welding quality. The part of the rear sill where the sound-absorbing cotton needs to be installed is designed to be inclined, which makes it more convenient for employees to perform the welding operation, reduces the work intensity, and improves the work efficiency.

[0017] The utility model will be further described below in conjunction with the drawings and embodiments.

[0018] Please refer to Figures 1 to 4 , a welding support tooling for the rear sill, which includes a base 1. A plurality of profiling seats 2 are firmly installed above the base 1, and the function of these profiling seats 2 is to provide stable support for the rear sill 7. A profiling surface 3 that perfectly matches the surface of the profiling seat 2 is designed on the top of each profiling seat 2, so as to better adapt to the shape of the rear sill 7. It is worth mentioning that these profiling seats 2 are arranged in parallel, and this layout not only helps to achieve uniform support for the rear sill 7, but also ensures its stability.

[0019] On the top of the base 1, a rear sill lock groove support seat 4 is also specially provided. There is a profiling part 5 on the top of this support seat that matches the rear sill lock groove 8, so that the rear sill 7 can be placed on the tooling more tightly and stably. To further enhance the stability, a positioning column 6 is fixed on the profiling part 5, and the main function of this positioning column 6 is to limit the lock cover plate 9 to ensure that it will not move during the welding process.

[0020] When the tailgate 7 is placed on the supporting tool, the part where the sound-absorbing cotton needs to be installed will naturally present an inclined state. This design is very user-friendly because it may bring greater convenience to employees when performing welding operations.

[0021] When the sound-absorbing cotton is welded and fixed, the welding part will face the contour seat 2. Such a design can greatly improve the accuracy and stability of welding, thereby effectively preventing the product from being deformed during the welding process.

[0022] In addition, when the tailgate 7 is placed on the tooling, its end will remain flush with the contoured seat 2 at the end of the base 1. This detail design is very critical because it ensures that the positioning of the tailgate 7 on the tooling is accurate, providing a strong guarantee for subsequent welding work.

[0023] Specific rectification measures: Place the tail door sill 7 on the supporting fixture, support it through the contoured seat 2, and weld it to ensure that the tail door sill 7 is convenient to weld the sound-absorbing cotton and does not deform.

[0024] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
