Ultrasonic flaw detector with high detection accuracy

Abstract

The invention relates to an ultrasonic flaw detector with high detection accuracy. The detector comprises a shell, a touch screen, at least two buttons and at least two moving wheels, further comprises a detection mechanism, a clearing mechanism and a central control mechanism, wherein the clearing mechanism comprises a connection port, a pedestal, a polishing block, a switching component, two lifting components and two power components, and the detection mechanism comprises a driving component, a driving shaft, a second gear, a moving block, a transmission bar, a hydraulic cylinder, a connection column and a probe. In the ultrasonic flaw detector with high detection accuracy, with the clearing mechanism, a surface of a workpiece can be processed before detection, thus, the surface of theworkpiece can be kept clean and flat, and detection accuracy of the ultrasonic flaw detector is improved; by the detection mechanism, automatic regulation of a probe angle can be realized, automationdegree of the ultrasonic flaw detector is improved, and detection efficiency of the ultrasonic flaw detector is also improved.

Description

technical field [0001] The invention relates to the field of ultrasonic flaw detection equipment, in particular to an ultrasonic flaw detector with high detection accuracy. Background technique [0002] Ultrasonic flaw detector is a method that uses ultrasonic energy to penetrate deep into metal materials, and when one section enters another section, reflection occurs at the edge of the interface to inspect parts defects. When the ultrasonic beam passes from the surface of the part through the probe, To the inside of the metal, when a defect and the bottom surface of the part are encountered, reflected waves will be generated respectively, and a pulse waveform will be formed on the fluorescent screen, and the position and size of the defect can be judged according to these pulse waveforms. [0003] During the use of general ultrasonic flaw detectors, if there are welding spatter, scale, pits and rust on the surface of the detected workpiece, it will affect the detection resu...

AI Technical Summary

Problems solved by technology

[0003] During the use of general ultrasonic flaw detectors, if there are welding spatter, scale, pits and rust on the surface of the detected workpiece, it will affect the detection results of the ultrasonic flaw detector, thereby reducing the accuracy of the ultrasonic flaw detector. Not only that, when people generally detect the workpiece, they need to use the staff to hold the probe to detect the surface of the workpiece for a long time, which is not only inefficient, but also the staff will hold the probe for a long time, which will cause hand discomfort and reduce the It reduces the experience of the staff and reduces the practicability of the ultrasonic flaw detector
