Problems solved by technology

[0002] Most of the sensor detection surfaces used in the prior art are planes, but in practical applications it is often necessary to detect the internal structure of arc-shaped workpieces (such as steel pipes, round steel, etc.). This will cause weak contact and affect the quality of the sound beam so that it cannot meet the requirements of use; and the general method used to detect curved workpieces is to divide the workpiece into multiple "like plane" parts to complete the detection of the entire workpiece, which is not only time-consuming and laborious, but also It is difficult to guarantee the detection accuracy; and the use of dual probes or even multiple probes to detect curved surface workpieces will increase cost and time-consuming

Abstract

The invention discloses an ultrasonic phased array probe for detecting a curved surface workpiece. The probe comprises a flexible array energy converter which is fixed through two splints mutually forming an angle, wherein a coaxial cable is led out from the flexible array energy converter, is arranged in a shell and is connected with a coaxial cable interface; an angle fine tuning device which is used for changing the curvature of the flexible array energy converter is fixed on the splints; the angle fine tuning device comprises a screw rod and a knob; the screw rod is arranged in the shell in the manner of screw-thread fit; the knob is used for driving the screw rod to move forward or backward in the shell through the thread; one end of the screw rod is in contact with the rotatable splints while the other end is in contact with the knob; when the knob rotation is formed, the screw rod can drive the splint in contact with the screw rod to increase or reduce the angle between the two splints; and a spring is connected between the two splints. The ultrasonic phased array probe is simple in structure, is capable of adapting to various arced workpieces and being in full contact with the workpieces, and is high in detection quality. The curvature of the probe is adjustable and can be adjusted correspondingly according to the application requirements and the adaptability is strong.

Description

technical field [0001] The invention relates to an ultrasonic phased array probe, in particular to an ultrasonic phased array probe capable of detecting curved surface workpieces. Background technique [0002] Most of the sensor detection surfaces used in the prior art are planes, but in practical applications, it is often necessary to detect the internal structure of arc-shaped workpieces (such as steel pipes, round steel, etc.). At this time, the plane sensor is in point contact or line contact with the workpiece surface. This will cause weak contact, affect the quality of the sound beam and thus fail to meet the requirements of use; and the general method used to detect curved workpieces is to divide the workpiece into multiple "like plane" parts to complete the detection of the entire workpiece, which is not only time-consuming and laborious, but also It is difficult to guarantee the detection accuracy; and the use of dual probes or even multiple probes to detect curved ...
