Ultrasonic flaw detector with high detection efficiency and pretreatment function

Abstract

The invention relates to an ultrasonic flaw detector with high detection efficiency and a pretreatment function. The ultrasonic flaw detector comprises a main body, a display screen, at least two control buttons and at least two moving wheels. The ultrasonic flaw detector also comprises a detecting mechanism, a cleaning mechanism and a central control mechanism. The cleaning mechanism comprises anopening, a base, a cleaning brush, a switching assembly, two lifting assemblies and two power components. The detecting mechanism comprises a driving component, a rotating shaft, a second gear, a second lifting block, a transmission rod, a cylinder, a fixing rod and a probe. In the ultrasonic flaw detector with high detection efficiency and a pretreatment function, through the cleaning mechanism,the surface of a workpiece can be processed before the inspection so that the surface of the workpiece is clean and flat and the accuracy of the ultrasonic flaw detector is improved. Through the detecting mechanism, the probe angle can be automatically adjusted so that the automation degree of the ultrasonic flaw detector is improved and the detection efficiency of the ultrasonic flaw detector isimproved.

Description

technical field [0001] The invention relates to the field of ultrasonic flaw detection equipment, in particular to an ultrasonic flaw detector with a preprocessing function and high detection efficiency. 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...

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
