Embodiment 1

[0032] This embodiment proposes an ultrasonic testing device 1 for testing aviation rivets, such as Figure 1-Figure 3 As shown, it includes an ultrasonic transducer 11 and a base 12. The lower surface of the base 12 is provided with an assembly port 132 and several couplant spray ports 122. The port 122 communicates with a couplant channel 123 , and the couplant channel 123 also has a couplant replenishment port 124 .

[0033] Ultrasonic transducer 11 utilizes the propagation characteristics determined by the high frequency and short wavelength of ultrasonic waves, the uniform propagation of ultrasonic waves in parts, and the characteristics of reflection and refraction when encountering interfaces during propagation, so that defects in workpieces can be found. When there is no damage in the workpiece, the sound wave goes directly to the bottom surface of the workpiece, and is fully reflected back when it meets the interface. When there is a flaw in the workpiece perpendicul...

Abstract

The invention discloses an ultrasonic detection device for detecting an aviation rivet. The ultrasonic detection device comprises an ultrasonic transducer; and a base, wherein an assembling opening and a plurality of coupling agent spraying openings are formed in the lower surface of the base, the ultrasonic transducer is arranged in the assembling opening, a coupling agent flow channel communicated with the coupling agent spraying openings is formed in the base, and the coupling agent flow channel is further provided with a coupling agent supplementing opening. According to the ultrasonic detection device for detecting the aviation rivets, the coupling agent flow channel is formed in the base and the coupling agent supplementing opening is used for being connected with an external coupling agent source, so that a coupling agent can be sprayed out of the coupling agent spraying opening and automatically guided into the surface of a detected object, and detection can be completed only by operating the ultrasonic detection device by one person; and the detection efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of ultrasonic detection, and in particular relates to an ultrasonic detection device for detecting aviation rivets. Background technique [0002] At present, the fuselage and wing structures of an aircraft are measured in tens of meters, and the internal structure is also extremely complex, which cannot be integrally formed like a car body. Rivets are required to join the loose parts into an aircraft structure. For an aircraft, due to its large size, tens of thousands of connecting rivets are required at least, and millions of rivets are required at most. [0003] Every nail and rivet on an aircraft is related to flight safety, and the reliability of connecting rivets is an important part of flight safety testing. The most important thing in the aviation industry is quality consistency. It is required that the quality of the first rivet produced must be consistent with that of tens of millions of rivets af...
