Description

Technical Field

[0001] The utility model relates to the technical field of aircraft assembly, and particularly relates to a flexible positioning and supporting device for a bulging alignment plate. Background Art

[0002] In the current docking and assembly work of aircraft parts, the insert docking and assembly for shape retention is an important part of the whole aircraft assembly. The characteristics of part fitting and riveting are that the parts have large stresses and there are certain step differences. It requires coordination of manual labor, and has high requirements for interchangeability and the quick operation of workers' experience. In the insert docking and assembly, the docking and matching of the bulging alignment plate is more difficult. The docking of the bulging alignment plate requires ensuring that one end of the two alignment plates is fitted and riveted, and the other end has a certain distance. Most of the existing riveting and shape retention assemblies are mechanical and single, and mostly manual operations. Assembly mostly relies on the work experience of workers, and one section corresponds to one part, resulting in a large number of tools involved in the assembly work, making the tool recognition extremely low, time-consuming and laborious in operation, and unable to improve the assembly efficiency and accuracy.

[0003] In order to solve the problems of single and insufficient fixed surfaces of various aircraft part assembly tools, especially for the riveting assembly of the bulging alignment plate, and the problems that most are manual or vise operations and overly rely on manual experience. The utility model provides a flexible positioning and supporting device for a bulging alignment plate for riveting assembly, which can greatly reduce the manual error tolerance rate. Summary of the Utility Model

One ends of the two threaded guide rods are respectively threadedly connected to both ends of the double-threaded guide cylinder, and the other ends of the threaded guide rods are fixedly connected to the triangular bracket assemblies. The side of the triangular bracket assembly away from the threaded guide rod is in contact with the bulging alignment plate.

[0007] As a preferred technical solution, the triangular support assembly includes a circular ring, a plurality of support rods and a disc. The diameter of the circular ring is larger than that of the disc. The support rods are inclined. One end of the support rod is fixedly connected to the circular ring, and the other end of the support rod is fixedly connected to the disc.

[0019] Embodiment

[0020] As Figure 1-2 shown, a flexible positioning and supporting device for a bulging mating plate includes two triangular bracket assemblies and a telescopic assembly. The telescopic assembly includes two threaded guide rods 5 and a double-threaded guide cylinder 6. Threads are provided at both ends of the inner wall of the double-threaded guide cylinder 6, and the thread directions at both ends of the double-threaded guide cylinder 6 are opposite. One ends of the two threaded guide rods 5 are respectively threadedly connected to both ends of the double-threaded guide cylinder 6, and the other ends of the threaded guide rods 5 are fixedly connected to the triangular bracket assemblies. The sides of the triangular bracket assemblies away from the threaded guide rods 5 are in contact with the bulging mating plate 1.

[0021] It should be noted that by setting the triangular support assembly as the main load-bearing body of the entire structure, the bulging mating plate 1 to be riveted is supported, ensuring the stability of the assembly work. By setting the telescopic assembly, the distance between the two triangular support assemblies is adjusted to meet the riveting requirements for different thicknesses of insert-like parts. Specifically, the two threaded guide rods 5 are respectively threadedly connected to the left- and right-handed threads in the threaded guide cylinder. By rotating the threaded guide cylinder, the two threaded guide rods 5 are simultaneously extended or contracted, so as to adjust the distance between the two triangular support assemblies and adapt to the installation spacing between different insert parts.

[0022] In some feasible embodiments, the triangular support assembly includes a ring 2, a plurality of support rods 3 and a disc 4. The diameter of the ring 2 is larger than that of the disc 4. The support rods 3 are inclined. One end of the support rod 3 is fixedly connected to the ring 2, and the other end of the support rod 3 is fixedly connected to the disc 4. The side of the disc 4 away from the support rod 3 is fixedly connected to the threaded guide rod 5, and the side of the ring 2 away from the support rod 3 is attached to the bulging mating plate 1. The structure of the triangular support assembly is based on the stability principle of a triangle, so the triangular support assembly has good stability.

[0023] During use, first rotate the threaded guide cylinder so that the length of the entire support device meets the installation distance between the two bulging mating plates 1. Then, place the two bulging mating plates 1 to be riveted on the ring 2 of the triangular support assembly respectively. After adjusting the corresponding positions, use a C-clamp to clamp and fix them, and then perform the riveting operation.

[0024] In addition, it should be understood that although this specification is described according to embodiments, not every embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art. So far, the embodiments of the present disclosure have been described in detail. In order to avoid obscuring the concept of the present disclosure, some details well known in the art have not been described. Those skilled in the art can clearly understand how to implement the technical solutions disclosed here based on the above description. The scope of the present disclosure is defined by the appended claims.
