Ultrasonic head for pulse-echo multichannel inspection

摘要

Ultrasonic head for pulse-echo multichannel inspection applied to flat and curved surfaces, which is connected to a displacement system (3), and which comprises a chassis (1) housing a tilting frame (4) joined to said chassis via a first point of rotation (1a) and a second point of rotation (1b) which define a main tilting axis (1c) around which the tilting frame (4) rotates, said tilting frame (4) presenting a set of feeler-carriers (2) in its central opening (4h) which carry an array of ultrasonic feelers (12), said array of feel-carriers (2) being able to rotate around at least one axis of rotation (5, 5a, 5b) transverse to the main tilting axis (1c) in an independent movement to that made by the tilting frame (4), the tilting frame (4) being able to be divided into two secondary frames (6, 8) which rotate independently of the rotation of the tilting frame (4).
