Airplane pneumatic riveting operation qualification determination device and method

Abstract

The invention provides an airplane pneumatic riveting operation qualification determination device and method and relates to the aerospace assembly manufacturing field. The device comprises a top iron housing, a mounting foundation, a combined selection board, a rigid spring, an embedded module and a sensor. According to the determination method, through measuring mechanics and vibration signals during riveting of different materials and thick boards, comparison with reasonable process test determination indexes and curves inputted to an embedded system is carried out, and objective determination of riveting operation qualification is carried out. The device and the method are advantaged in that operation is simple, a determination result is rapid and accurate and has strong in-linearity, riveting detection efficiency can be effectively improved, and an auxiliary method can be provided for quality determination of morphological detection.

Description

technical field [0001] The invention relates to the fields of assembly and manufacture of automobiles, ships, aerospace components and components, in particular to a device and method for judging the qualification of aircraft pneumatic riveting operations. Background technique [0002] Aircraft safety issues mainly stem from the assembly quality of aircraft. As the main technology of aircraft assembly, riveting quality directly determines the safety performance of aircraft. Therefore, the riveting quality must be strictly controlled in aircraft assembly. At present, in order to ensure the consistency of riveting quality, foreign countries have developed automatic drilling and riveting equipment, using the method of pressure riveting, but because it can only be used for open parts and inaccurate detection of the normal direction, its use is greatly restricted, and it is often used It is connected to the barrel section of straight sections such as airplanes. Therefore, the no...

Problems solved by technology

[0003] The manual riveting quality inspection of aircraft is an important issue. At present, the domestic riveting inspection method is mainly to judge the riveting quality through the rivet appearance inspection after the riveting is completed, and the operation in the riveting process cannot be objectively evaluated.

[0004] Therefore, those skilled in the art are committed to developing a device and method for judging the qualifiedness of aircraft pneumatic riveting operation, which can solve the problem of high cost of interference detection in riveting detection in the process of aircraft riveting, complicated process, and excessive reliance on subjective detection methods in shape detection.
