High-precision ultrasonic detection equipment for flaw detection of workpiece

Abstract

The invention relates to high-precision ultrasonic detection equipment for workpiece flaw detection. The high-precision ultrasonic detection equipment comprises a host, wires, a connecting rod and a probe; one end of the connecting rod is arranged on the main machine through a wire. The probe is arranged on the connecting rod; the probe is electrically connected with the host through a wire. A cleaning mechanism and an auxiliary mechanism are arranged at the end, away from the wire, of the connecting rod. The auxiliary mechanism comprises a power assembly, a rotating rod, a rotating shaft, a grinding assembly, two first bearings and two supporting rods. The grinding assembly comprises a rotating pipe, a second bearing, a grinding disc and a driving unit. The cleaning mechanism is positioned between the probe and the connecting rod; the cleaning mechanism comprises a first motor, a driving disc, a cleaning disc, an electromagnet and two transmission assemblies, the high-precision ultrasonic detection equipment for workpiece flaw detection achieves the function of removing impurities on a probe through the cleaning mechanism, and in addition, the function of polishing a workpiece isachieved through an auxiliary mechanism.

Description

technical field [0001] The invention relates to the field of ultrasonic detection, in particular to a high-precision ultrasonic detection device for flaw detection of workpieces. Background technique [0002] Ultrasonic testing is also called ultrasonic testing. It uses ultrasonic technology for testing. It is one of the five conventional nondestructive testing methods. Ultrasonic flaw detector is a kind of ultrasonic testing instrument. Ultrasonic flaw detection uses ultrasonic energy to penetrate metal materials. Deep, and from one section into another section, the reflection occurs at the edge of the interface to check the defect of the part. When the ultrasonic beam passes from the surface of the part from the probe to the inside of the metal, when it encounters the defect and the bottom surface of the part, it will Reflected waves are generated separately to form pulse waveforms on the fluorescent screen, and the position and size of defects are judged based on these pu...

AI Technical Summary

Problems solved by technology

[0003] During the use of existing ultrasonic flaw detectors, when the surface roughness of the workpiece is too large, the coupling effect between the probe and the contact surface will be poor, the reflected echo will be low, and the echo signal cannot even be received. After the workpiece is in contact, more impurities will be generated on the surface, and impurities will reduce the detection accuracy
