Abstract
The invention relates to an angle-adjustable ultrasonic probe. The ultrasonic probe comprises a piezoelectric probe, a wedge block and a coupling agent. A square groove is formed in the upper end face of the wedge block. The bottom face of the square groove is an arc surface. The coupling agent is arranged inside the square groove. The end of the piezoelectric probe stretches into the coupling agent. The piezoelectric probe is rotationally connected with the wedge block. A sliding rail is arranged on the upper surface of the wedge block. A first connecting rod is hinged to a shell of the piezoelectric probe. A second connecting rod is hinged to the first connecting rod. The tail end of the second connecting rod is hinged to a sliding block matched with the sliding rail. The probe slides on the sliding rail through the sliding block, so that the first connecting rod and the second connecting rod rotate, the piezoelectric probe is driven to rotate, the incident angle of the probe is changed, the application range of the probe is enlarged, and the structure is simple.
Description
Technical field
The present invention relates to UT (Ultrasonic Testing) technical field, especially a kind of angle adjustable ultrasonic probe.
Background technology
Ultrasound examination is one of large common detection methods of five in field of non destructive testing, and it possesses the advantages such as environmental pollution is little, is therefore widely used in work efficiency Non-Destructive Testing.For generation of ultrasonic excitation signals with to receive the parts of ultrasonic return signal be ultrasonic probe in ultrasound examination.UT (Ultrasonic Testing) is divided into again impulse type and diffraction type, and general impulsive failure detector mainly make use of the principle of reflection of ultrasound wave in measured workpiece, ultrasound wave is produced by piezoelectric chip resonance, and enter into measured workpiece generation refraction and reflection, and according to reflection and refraction principle, before ultrasound wave enters workpiece, need certain incident angle.
Ultrasonic probe of the prior art is all generally that a kind of workpiece of the corresponding type of probe of model detects, and use limitation comparatively large, and for some unconventional workpiece, the best do not matched is popped one's head in, and makes Detection results undesirable.
Summary of the invention
The technical problem to be solved in the present invention is: fix to solve existing ultrasonic probe incident angle, uses the problem that limitation is larger, provides a kind of angle adjustable ultrasonic probe.
The technical solution adopted for the present invention to solve the technical problems is: a kind of angle adjustable ultrasonic probe, comprise piezoelectric probe, voussoir and couplant, described voussoir upper surface is provided with square groove, described square groove bottom surface is arc surface, described couplant is arranged in square groove, described piezoelectric probe end is stretched in couplant, piezoelectric probe and voussoir are rotationally connected, the upper surface of described voussoir is provided with slide rail, the shell of described piezoelectric probe is hinged with first connecting rod, described first connecting rod is hinged with second connecting rod, the end of described second connecting rod is hinged with the slide block matched with described slide rail.
Piezoelectric probe and voussoir are rotationally connected, promote slide block to slide on slide rail, first connecting rod and second connecting rod are rotated, thus drive piezoelectric probe to rotate, slide block is made to stop when piezoelectric probe goes to the angle of needs mobile, the incident angle of probe can be changed as required, increase the range of application of probe.
As preferably, the cross section of described slide rail is T-shaped, and the slide rail of T section is comparatively common, and cost is lower.
As preferably, described slide rail is provided with block near a section of voussoir edge, and anti-limited slip block skids off slide rail.
The invention has the beneficial effects as follows, this probe is slided on slide rail by slide block, and first connecting rod and second connecting rod are rotated, thus drives piezoelectric probe to rotate, change the incident angle of probe, increase the range of application of probe, structure is simple.
