Self-coupling ultrasonic detection probe device

Abstract

The invention relates to a self-coupling ultrasonic detection probe device. The device comprises a supporting component and a rolling component, wherein the supporting component comprises a support, a water tank, a hollow shaft and nuts, the water tank is installed above the support, the hollow shaft penetrates through the lower end of the support, and two ends of the hollow shaft are fastened through the nuts; the rolling component comprises a probe, two sealing bearings, round plates and a rubber membrane, the probe is installed on the hollow shaft and located between the two sealing bearings, the sealing bearings are embedded in circle centers of the round plates and installed on the hollow shaft, a position between the two round plates is coated with the rubber membrane, a sealed space is formed between the two round plates, and the probe is connected with an ultrasonic detector through a lead. The self-coupling ultrasonic detection probe device is simple in structure, convenient to operate and high in detection efficiency.

Description

Technical field: [0001] The invention relates to the field of ultrasonic detection equipment, in particular to a self-coupling ultrasonic detection probe device. Background technique: [0002] Ultrasonic testing technology is one of the commonly used non-destructive testing techniques. With the development of nondestructive testing technology, ultrasonic testing technology is widely used in the quality testing of pressure vessels, oil pipelines, mechanical parts and other fields due to its high sensitivity, fast speed, low cost, and harmlessness to the human body. An ultrasonic probe is a device that emits and receives ultrasonic signals. During ultrasonic testing, the air between the probe and the workpiece will interfere with signal transmission and reduce the accuracy of the test. Therefore, it is necessary to moisten the probe and the workpiece with water to remove the air between the two to have a better coupling effect. During the detection process, the staff holds t...

AI Technical Summary

Problems solved by technology

During the detection process, the staff holds the probe and moves on the surface of the workpiece. The force applied to the probe should be uniform and stable. Too little force will easily cause poor coupling effect and affect the accuracy of detection, and even cause some minor defects to be missed. If the force is too large It will cause accelerated wear of the plexiglass on the surface of the probe and shorten the service life of the probe

The above process is inconvenient to operate, the efficiency is low, and the detection accuracy is easily affected
