Description

Technical Field

[0001] This utility model relates to the technical field of aviation pipeline shaping devices, and more specifically, to an aviation pipeline shaping fixture. Background Technology

[0002] Aviation piping is a type of piping used in aircraft to supply fluids. Aviation piping is mostly irregularly shaped, and certain dimensional deviations are inevitable during the manufacturing process. As a result, when existing aviation piping is connected to corresponding components in the aircraft, after one end of the aviation piping is connected to the interface on one component, the other end of the aviation piping will have assembly tolerances with the interface on another component. This leads to the disadvantage of inconvenient assembly of aviation piping, and the bending of aviation piping during the assembly process can easily cause damage to the aviation piping. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide an aviation pipeline shaping fixture that can pre-shape aviation pipelines so that the shape of the aviation pipelines meets the assembly requirements.

[0004] This utility model provides an aviation pipeline shaping fixture, including a fixture body; a plurality of support blocks for supporting aviation pipelines are fixed on the fixture body, the plurality of support blocks are distributed at intervals along the extension direction of the aviation pipeline, and each support block has a groove at its upper end, each groove being used to fit with a portion of the aviation pipeline at a corresponding position; two support seats are also fixed on the fixture body, and each support seat is connected to a pushing component, the two pushing components being used to abut against one end of the aviation pipeline and push the end of the aviation pipeline to achieve shaping of the end of the aviation pipeline.

[0005] By adopting the above-mentioned structure, this utility model can pre-shape the aviation pipeline after its production is completed and before it leaves the factory, so that the shape of the aviation pipeline meets the assembly requirements. This avoids assembly tolerances when the aviation pipeline is subsequently assembled onto the aircraft, thus facilitating the assembly of the aviation pipeline and preventing the aviation pipeline from being damaged during the assembly process.

[0006] In one possible implementation, each pusher assembly includes a bolt and a pusher pin; the threaded portion of each bolt is horizontally inserted into a support on the corresponding side and threadedly connected to the support; the outer end of the pusher pin is coaxially rotatably connected to the threaded portion of the bolt on the corresponding side; a plug-in post is coaxially provided on the inner end of the pusher pin, which is used to coaxially insert into the end of the aviation pipeline so that the inner end of the pusher pin abuts against the end of the aviation pipeline; when the bolt is tightened, the pusher pin is used to push the end of the aviation pipeline to achieve shaping of the aviation pipeline; by using this pusher assembly, the plug-in post can be pre-loaded... First, it is inserted into the end of the aviation pipeline. When the bolt is tightened so that it gradually pushes the ejector pin, the ejector pin can push the end of the aviation pipeline to achieve the shaping of the aviation pipeline. After the bolt is tightened to the end towards the support seat, the shaping of the aviation pipeline is completed. That is, the travel of the ejector pin pushing the end of the aviation pipeline is controlled by the travel of the bolt relative to the support seat, which makes it easy to control the amount of shaping of the aviation pipeline. In addition, under the action of the ejector pin, rotational friction between the bolt thread and the end of the aviation pipeline can be avoided, that is, wear on the end of the aviation pipeline can be avoided.

[0007] In one possible implementation, a plug is coaxially provided on the outer end of the ejector pin, and a socket is provided on the inner end of the bolt's threaded portion. Each plug is coaxially inserted into the socket on the corresponding side and rotates with the socket. With this structure, after the plug is coaxially inserted into the socket, the outer end of the ejector pin can be reliably connected to the bolt's threaded portion in a coaxial rotational manner.

[0008] In one possible implementation, an annular chamfered surface is provided on the outer peripheral wall of the end of the plug-in pin away from the ejector pin. The annular chamfered surface is used to guide and mate with the inner wall of the end of the aviation pipeline to facilitate the insertion of the plug-in pin into the end of the aviation pipeline. With this structure, when the plug-in pin is inserted into the end of the aviation pipeline, the annular chamfered surface can mate and guide with the inner wall of the end of the aviation pipeline to facilitate the insertion of the plug-in pin into the end of the aviation pipeline, thus facilitating the insertion of the plug-in pin into the end of the aviation pipeline.
