Abstract

An aircraft fuel system catheter positioning structure and positioning method. The positioning structure contains clamping card holes, end -facial positioning boards, and axial connectors.The device is used to connect the positioning between the upper ring of the holding card and the end -facial positioning plate according to the scheduled gap. The outer side of the end -facial positioning plate is provided with a ring positioning line that matches the outer diameter of the connected duct.The duct limit, adjust the gap between the upper ring and the end surface positioning plate, and press the tube of the right duct to fix the ring positioning line on the outside of the end surface positioning plate.

Description

technical field [0001] The present application belongs to an assembly and production technology of an aircraft fuel system conduit, in particular to a positioning structure and a positioning method of an aircraft fuel system conduit. Background technique [0002] Most of the pipeline connections in the aircraft fuel system use flexible connections, that is, the pipes with pipe joints, pipe sleeves, seals and clamps are assembled together, and then fixed by brackets and pipe clamps on the wall in the engine room. The reserved gap for butt joint docking is 3-6mm, and the axis deviation is not more than 3°. In the process of aircraft assembly and production, the fuel system pipes are connected in sections when they are installed and connected in the cabin. First, assemble the flexible joints and seals of each section of pipes, and then fasten them with clamps. After all the system pipes are connected, airtight or In the pressure test, it is necessary to ensure that the joints ...
