Problems solved by technology

It is relatively easy to realize the ultrasonic automatic detection of workpieces with simple shapes, such as planes, rotating bodies, and open curved surface components, but it is difficult to realize automatic detection of workpieces with complex curved surfaces (such as special components containing grooves, corners, etc.), because There is not enough space for the manipulator to enter the surface of such components to inspect the workpiece

Embodiment Construction

[0038] figure 1 and figure 2 It is an ultrasonic detection device, which includes a waveguide 15, a spray head 11, a liquid storage chamber 12, an ultrasonic transducer gland 16, and an ultrasonic transducer bracket 13, which are sequentially connected by bolts and nuts and arranged hollow along the connection direction. One end of the step 31 on the ultrasonic transducer 3 is pressed on the end face of the liquid storage bin 12, and the other end is pressed in the circular groove on the ultrasonic transducer gland 16, so that the ultrasonic transducer 3 is in the ultrasonic detection device The front and rear positions of the ultrasonic transducer are limited so that the ultrasonic transducer 3 cannot move forward and backward in the ultrasonic testing device. In addition, the ultrasonic transducer gland 16 tightly presses the step 31 of the ultrasonic transducer against the end face of the liquid storage bin 12, and the step 31 blocks the through hole 123 of the liquid sto...

Abstract

The invention discloses an ultrasonic testing device. The ultrasonic testing device is provided with a waveguide, which can replace a manipulator testing system to detect the surface quality of complex curved composite material workpieces that are difficult to reach, and can pump coupling liquid into the device. The coupling liquid enters the waveguide and is sprayed onto the surface of the workpiece. Ultrasonic waves can propagate in the waveguide to reach the surface of the workpiece and penetrate the workpiece to detect the quality of the workpiece. In addition, a method for detecting the quality of workpieces on complex curved surfaces is proposed using the ultrasonic testing device. , set up an ultrasonic testing device on both sides of the workpiece, and connect a waveguide to the ultrasonic testing device on one side or both sides, so that the ultrasonic energy can be transmitted to the workpiece surface or received from the workpiece surface, so that complex curved surface composite materials can be tested The quality of the workpiece is inspected.

Description

technical field [0001] The invention belongs to the technical field of non-destructive ultrasonic testing, in particular to an ultrasonic testing device and method. Background technique [0002] With the maturation of material science and manufacturing technology, more and more components with complex shapes, especially composite components with advantages such as high strength, high rigidity, high temperature and high pressure resistance, fatigue resistance and corrosion resistance, have been applied. In aerospace, military industry, automobile and other fields, the tooling consumption and application level of composite materials have become one of the important symbols of the advancement of modern aviation equipment. [0003] Due to the complex manufacturing process of the composite material structure, defects such as cracks, holes, and delamination inevitably exist during the manufacturing process and use, which will have a direct impact on the quality of the workpiece. ...
