Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of planar ultrasonic testing, and more specifically, particularly relates to a planar ultrasonic oblique opposite shooting device. Background Technique
[0002] Currently, in the ultrasonic testing of certain planes, two ultrasonic probes are required to work in a form of one transmitting and one receiving. The two ultrasonic probes are arranged oppositely on the flat plate at the same incident angle. After the ultrasonic wave is emitted from the transmitting probe, it obliquely enters the workpiece and is received by the receiving probe after being reflected by the bottom surface. During the testing process, the distances and angles of the two probes need to be adjusted. However, the existing devices need to be manually adjusted throughout the process, which cannot ensure that the adjusted angles of the two ultrasonic probes are consistent, resulting in low detection accuracy. Moreover, the adjusted angles cannot be observed in real time, and the ultrasonic probes cannot be accurately controlled, so the obtained experimental data is not accurate enough.
