Multipurpose ultrasonic flaw detection device

Abstract

The invention relates to a multipurpose ultrasonic flaw detection device. The device comprises a body and an upper computer; a conventional ultrasonic probe assembly is arranged on the body; the conventional ultrasonic probe assembly comprises an ultrasonic transmitting probe and an ultrasonic receiving probe; the upper computer is connected with an electric control board in the body in a wired or wireless connection mode; the body is further provided with a composite material probe assembly, and the composite material probe assembly comprises an acoustic impedance probe and a knocking probe; and the ultrasonic transmitting probe, the ultrasonic receiving probe, the acoustic impedance probe and the knocking probe are all connected with the electric control board in the body through wires. The multipurpose ultrasonic flaw detection device disclosed by the invention is high in detection efficiency, low in cost and easy to carry.

Description

technical field [0001] The invention relates to flaw detection, in particular to a multipurpose ultrasonic flaw detection device. Background technique [0002] The use of composite materials in aircraft manufacturing is currently growing dramatically. Major airframe manufacturers such as Boeing and Airbus have greatly increased their use of composite materials in their respective commercial aircraft manufacturing. Almost the entire fuselage of the Boeing 787 is made of composite materials, while the Airbus A380 and A350 also add a lot of composite material structure. Additionally, regional and business jet manufacturers have increased their use of composite materials in the manufacture of their respective aircraft. The same increase in the use of composites has been seen in the manufacture of military aircraft, such as the F22 fighter jet and the A400 transport aircraft. The fuselage and wing parts of these aircraft are all replaced by carbon fiber reinforced laminated co...

AI Technical Summary

Problems solved by technology

Due to the problems of materials, structure, production process, etc., there are many types of defects in composite materials and glued structures, so it is difficult to achieve comprehensive comprehensive detection with one detection method. For this reason, inspectors need to use a variety of different types of detection equipment The materials are tested separately, which makes the operator have to carry a variety of testing equipment when testing, and the size and weight of various testing equipment are not easy, and it is very inconvenient to carry
