PROBE ASSEMBLY FOR NONDESTRUCTIVE ULTRASONIC TESTING

摘要

A probe assembly for ultrasonic detection is provided to detect an object through an ultrasonic wave even if a test part of the object is vibrated or the position of the test part is not fixed, by using a housing vertically or horizontally pitching or yawing. A probe assembly(100) for ultrasonic detection is composed of an ultrasonic probe; a wedge for transmitting an ultrasonic wave to an object; a housing containing the ultrasonic probe and the wedge; and a housing support unit(20) fixed at the lower side of the housing to elastically support the housing in order to move the housing back and forth in one direction. The housing support unit comprises a base(17); a support shaft(13) settled to the base to hinge-combine one end portion to the lower part of the housing and relatively move the other end portion for the base in one direction; and a spring(15) of which one end is supported to the base and the other end is supported to the support shaft.
