Flexile technical quick-change adapting piece and connection method

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 ...

Problems solved by technology

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.

Bolt connection is a kind of detachable connection widely used on the aircraft body. It is characterized by simple operation and strict requirements on the control of pre-tightening force. However, the traditional bolt connection cannot meet the structural parts with high fatigue resistance requirements, and there are certain gaps in the connection.

The adhesive connection is also not detachable, and it is difficult to meet the requirements for the main load-bearing parts

In combination, these connection methods often have the characteristics of poor reliability, high requirements for connected parts, poor fatigue resistance, poor sealing, etc., which restrict the performance and life of the aircraft
