Description
(1) technical field
The utility model relates to the UT (Ultrasonic Testing) field, relates in particular to be used for the ultrasound wave coupling probe that longitudinal and transverse ripple is united flaw detection.
(2) background technology
Ultrasonic probe claims ultrasonic transducer again, and it is a kind of device of realizing that electric energy and acoustic energy are changed mutually.Because it is made with different processing technologys that tested workpiece is different material, therefore, the shape of workpiece and defective orientation, defects property, the defect type in the workpiece are also had nothing in common with each other, when prior art is implemented ultrasound examination to all kinds of defectives in the workpiece, according to the UT (Ultrasonic Testing) standard-required, method of detection commonly used has longitudinal wave testing method and transverse wave testing method.Longitudinal wave testing method adopts normal probe to survey, and it mainly detects the defective parallel with the metal works test surface, as layering, be mingled with, defective such as shrinkage cavity; Transverse wave testing method adopts angle probe to survey, and it mainly detects the defective that certain angle is arranged with the metal works test surface, as crackle, defective such as folding.Therefore, regulation according to the UT (Ultrasonic Testing) standard that has metal material now, implement the workpiece of compressional wave and detection with transversal waves for same requirement, the flaw detection step is: with normal probe workpiece is carried out the compressional wave flaw detection earlier, and then carry out detection with transversal waves with angle probe, though this method of detection can guarantee the quality of detecting a flaw, the efficient of detecting a flaw is lower, is unfavorable for the flaw detection of workpiece in enormous quantities.
(3) summary of the invention
The purpose of this utility model is to provide a kind of ultrasound wave coupling probe that longitudinal and transverse ripple is united flaw detection that is used for, this coupling probe adopts two groups of wafers to work simultaneously at diverse location, once flaw detection can be finished two kinds of carrying out flaw detection of longitudinal and transverse ripple, can obviously shorten the flaw detection time of workpiece, improve the flaw detection work efficiency.
The utility model is achieved in that a kind of being used to indulge, shear wave is united the ultrasound wave coupling probe of flaw detection, comprise shell, wafer, damping absorbs piece, matched coil, wedge, lead, electrode, it is characterized in that wafer is one group of compressional wave wafer and one group of shear-wave wafer, the compressional wave wafer is parallel with the searching surface of coupling probe, the searching surface of shear-wave wafer and coupling probe has angle, two groups of wafer one ends connect matched coil respectively by lead, the other end is connected with the two arrays of electrodes binding post respectively, two groups of wafers place each self-damping to absorb on the piece respectively, absorb interblock two dampings and be equipped with sound insulating layer, damping absorbs piece, sound insulating layer and matched coil place in the housing, and electrode terminal is housed on the wedge.
The utility model is on two diverse locations of coupling probe two groups of wafers to be installed, it is parallel with the workpiece test surface for one group of wafer, mainly transmit and receive compressional wave, workpiece is implemented the compressional wave flaw detection, and another group wafer and workpiece test surface form certain angle, mainly transmit and receive shear wave, workpiece is implemented detection with transversal waves by oblique incidence.Two groups of wafer one ends are connected with matched coil respectively by line, and the other end is connected with the two arrays of electrodes binding post respectively, and the mode of operation of two groups of wafers is single-shot list receipts and works alone.Because longitudinal and transverse ripple direction difference, therefore, ultrasonic wave acoustic beam can not produce interference between mutually, can realize that longitudinal and transverse ripple detects a flaw synchronously.
Compared with prior art, the utility model adopts two groups of wafers to work simultaneously at diverse location, once flaw detection can be finished the detection of two kinds of methods of detection of longitudinal and transverse ripple, can obviously shorten the flaw detection time of workpiece, improve flaw detection rhythm, for on-line automatic flaw detection improves flaw detection rhythm, effective guarantee is provided, thereby improves the work efficiency of flaw detection.
