Embodiment Construction

[0013] As shown in the figure, a probe base 2 is installed on one side of the housing 1, and an oblique probe is connected to the probe base. A sound-absorbing module 4 is installed in the probe wedge 5, and piezoelectric ceramic crystals 3 are installed on both sides thereof.

[0014] The piezoelectric ceramic crystal is lead zirconate titanate.

[0015] The probe wedge is a plexiglass wedge.

[0016] The probe wedge is composed of three sub-wedges with different angles, and a fourth piezoelectric ceramic wafer is pasted on the other side of the wedge, which is pasted with three piezoelectric ceramic wafers, to receive the ultrasonic energy returned in the circumferential direction. The combination angle of the wedges is determined according to the wall thickness of the detected workpiece, and there are many combinations.

Abstract

The invention provides a multi-angle circumferential detection ultrasonic wave angle probe. The multi-angle circumferential detection ultrasonic wave angle probe is characterized in that: a probe baseis arranged on one side of a shell; the probe base is connected with an angle probe body; a sound-absorbing module is arranged in a probe wedge block; and piezoelectric ceramic crystals are arrangedon two sides of the sound-absorbing module; the piezoelectric ceramic crystals are made from lead zirconate titanate; the probe wedge block is made of organic glass; the probe wedge block consists ofthree sub-wedge blocks of different angles; a fourth piezoelectric ceramic wafer is attached to the other side opposite to one side to which three piezoelectric ceramic wafers are attached of the wedge block in order to receive ultrasonic wave energy returned along the circumferential direction. The combination angle of the wedge block is determined according to the wall thickness of a detected workpiece. By adopting the angle probe provided by the invention, ultrasonic wave flaw detection on radial defect of locomotive wheels, vehicle wheels and a middle diameter pipeline and circumferentialflaw with a certain reflection area can be finished well. The multi-angle circumferential detection ultrasonic wave angle probe is suitable for performing multi-angle circumferential detection.

Description

technical field [0001] The invention relates to a multi-angle circumferential detection ultrasonic oblique probe used in the technical field of ultrasonic flaw detection. technical background [0002] In the detection of radial defects of locomotive wheels, vehicle wheels, and large and medium-diameter pipes with a certain thickness, the ultrasonic energy generated by the ultrasonic transducer cannot fully Inside this ring-shaped workpiece, a flaw detection blind zone is formed where the ultrasonic energy cannot cover, and it is impossible to effectively detect radial defects inside the workpiece and circumferential defects with a certain reflection area. For this purpose, a special multi-angle circumferential ultrasonic oblique probe is designed. Contents of the invention [0003] The object of the present invention is to provide a multi-angle circumferential detection ultrasonic oblique probe. The angle probe solves the technical problem of angle probe detection throug...
