The invention is high in efficiency, good in reliability and easy in usage, and has many measurement functions, uses one measurement method to replace various measurement methods and multiple times of measurement, and improves the quality of the airplane covering-riveting assembly surface and production efficiency.

Description

technical field [0001] The invention relates to the technical field of aviation manufacturing, in particular to a method for detecting the surface quality of aircraft skin riveted assembly. Background technique [0002] The role of the aircraft skin is to maintain the shape of the aircraft so that it has good aerodynamic characteristics. After the skin is subjected to aerodynamic action, the force is transmitted to the connected fuselage and wing frame. The force is complex, and the skin is in direct contact with the outside world. Therefore, not only the skin material is required to have high strength and good plasticity, but also a smooth surface. It has high corrosion resistance. [0003] In the modern aircraft riveting assembly process, aircraft skin surface quality control is an important technical index that affects riveting quality. The aircraft skin surface quality mainly includes the height of the rivet head relative to the aircraft skin, and the local deformation ...

Problems solved by technology

[0004] At the present stage, there is no detection method that can effectively detect various technical indicators of the riveted surface quality at the same time. The height of the riveted nail head relative to the aircraft skin is measured by using a triangular meter or online by using a contact sensor. The height value is calculated by side measurement; the width and step difference of the aircraft skin butt joint gap are obtained by manual measurement respectively, and the above measurement methods are all contact measurements; the local deformation of the aircraft skin around the rivet relies on manual visual inspection
