Abstract

The invention relates to an ultrasound A / B shaft detection device used for a complex structure, which can realize five-axle linkage of an ultrasound detection device and is used for ultrasound detection of various complex surfaces. The conventional three-axle linear motion can not satisfy the requirement that a central axis of a sensor is vertical to the surface of a to-be-detected material when the detection is carried out. Through the A / B shaft device, the rotation at any angle can be realized, as a result, the requirement is satisfied and the accuracy and the reliability of the detection are improved. The A / B shaft provided by the invention is particularly suitable for detecting the complex surfaces, such as inclined surfaces, canal surfaces and grooves.

Description

1. Technical field: [0001] The invention relates to the addition of an A / B axis structure on the basis of a conventional three-axis linkage ultrasonic detection device to realize five-axis linkage of the ultrasonic detection device, which is used for ultrasonic scanning of various components with complex shapes. 2. Background technology: [0002] As an important method of non-destructive testing, ultrasonic testing is widely used in the non-destructive testing of metal or composite materials such as engine cylinders, space shuttle impeller blades, impeller disc parts, shells, etc. . [0003] Conventional liquid immersion ultrasonic testing methods are generally divided into reflection type and transmission type. Both methods require the central axis of the probe to be perpendicular to the surface of the material to be tested. Usually, the X, Y, Z three-axis linear motion detection is to place the test piece in the water tank (water is the most common as the coupling agent),...
