Embodiment Construction

[0015] as attached figure 1 As shown, a quick-change flexible process connector for aircraft structure connection includes a connecting screw 1 , a bellows 2 , and a high lock nut 3 . The bellows 2 are set on the connecting screw 1, and they are placed in the structural holes to be connected, and the expansion degree of the bellows can be adjusted by tightening the high lock nut 3, so as to achieve the purpose of sealing connection. Changing bellows length, expansion joint geometry, bellows wall thickness or wave pitch can be used for different types of connections.

[0016] The working process of the quick-change flexible process connector is as follows:

[0017] (1) Select the connection parameters according to the shape, size and performance requirements of the parts to be connected.

[0018] 1) First, select the corrugated pipe 2 that meets the performance requirements according to the aperture size, depth and performance requirements of the parts to be connected. The o...

Abstract

The invention provides a flexile technical quick-change adapting piece and a connection method, belonging to the technical field of adapting pieces. The flexile technical quick-change adapting piece comprises a connecting screw rod (1), a corrugated pipe (2) and a high-locking nut (3), wherein the connecting screw rod (1) is successively composed of a bolt head (11), a screw rod (12) and a threaded section (13); the high-locking nut (3) is successively composed of a nut section and a screwing end socket (32), wherein the nut section is composed of an aperture section and a threaded section (31); a compression table (33) is arranged between the aperture section and the threaded section; when the high-locking nut (3) is screwed, one end of the corrugated pipe (2) extends into the aperture section of the high-locking nut (3); and the corrugated pipe (2) is compressed by the compression table (33) on the inner wall of the nut section for radial expansion so as to perform the action of tight coupling. When the adapting piece is damaged and loses efficacy, the adapting piece can be quickly repaired by replacing the corrugated pipe (2).

Description

technical field [0001] The invention is a newly designed quick-change flexible process connector and a connecting method, which are suitable for the connection and sealing of aircraft parts, aircraft composite materials and other products. Background technique [0002] Generally, the aircraft skin and related connections are connected by riveting, screwing and gluing. The riveting method is a non-removable connection, which has the advantages of easy to master the operation process and easy inspection of the quality, but the riveting method has some shortcomings in both structure and production, such as low fatigue performance, poor sealing of riveting seams, poor working conditions, damage Not easy to repair etc. Bolted connection is a kind of detachable connection widely used in aircraft body. It is characterized by simple operation and strict requirements on the control of pre-tightening force. However, traditional bolted connection cannot meet the structural parts with ...
