Description

Probe grinding machine for ultrasonic detection

Technical Field

The utility model relates to an ultrasonic inspection technical field relates to a be used for ultrasonic testing to examine coping machine with probe particularly.

Background

Generally, in a uniform material, the existence of defects will cause discontinuity of the material, which often causes inconsistency of acoustic impedance, and as known from reflection theorem, ultrasonic waves will be reflected on an interface between two media with different acoustic impedances, and the magnitude of the reflected energy is related to the difference of the acoustic impedances of the media on both sides of the interface and the orientation and the magnitude of the interface. An ultrasonic transmitting and receiving device with certain characteristics, which is assembled by taking a transducer as a main element, is often called a probe. The ultrasonic probe is one of the most important components forming an ultrasonic detection system, and the performance of the probe directly influences the ultrasonic detection capability and effect.

At present, a piezoelectric transducer probe is commonly used, and generally comprises a piezoelectric wafer, a damping block, a joint, a cable, a protective film and a shell. The tilt probe also typically includes a tilt wedge that angles the wafer to the plane of incidence. The wedge is a wedge attached to the front surface of the wafer in order to make ultrasonic waves incident obliquely on the detection surface in the oblique probe. The wedge makes the wafer of the probe and the surface of the workpiece form a strict included angle to ensure that the ultrasonic wave emitted by the wafer is obliquely incident to the interface of the wedge and the workpiece according to a set inclined angle, so that the required mode conversion can be generated at the interface to form the acoustic beam with a specific mode and an angle in the workpiece.

In the long-term use process of the existing in-service probe, due to the influence of factors such as uneven surface, poor finish, uneven pressure and the like of a workpiece, the detection surface of the probe is seriously abraded, the refraction angle of the probe is changed, and the flaw detection quality is influenced. Specifically speaking, when the front part of the probe is seriously worn (when the gripping force of the oblique probe is not uniform front and back, the front end of the oblique probe is worn more than the rear end of the oblique probe after long-time use), the refraction angle of the probe is reduced, the refraction angle of the probe is increased when the rear part of the oblique probe is worn, and when the left part and the right part of the probe are worn unevenly, the deflection angle of the main sound beam of the probe can exceed the standard, so that the main sound beam of the probe deviates from a detection part to cause missed detection, the worn probe needs to be repaired, and the detection surface is kept horizontal.
