The invention discloses an automatic flaw detection device and method based on ultrasonic technology, comprising a scanning frame, a moving base and an ultrasonic flaw detector, the moving base is located at the upper end of the scanning frame, the ultrasonic flaw detector is located at the upper end of the moving base, and the scanning frame There are tooth grooves on the side wall, and connecting seats are provided on both sides of the lower surface of the mobile base, and a rotating rod is rotatably connected to the connecting seats, and a rotating gear matching the tooth grooves is fixedly set on the rotating rod. In the present invention, by setting the ultrasonic flaw detector on the mobile base and movably connecting the mobile base to the scanning frame, the first motor can be used to rotate, and the first bevel gear to mesh with the second bevel gear to rotate, so that it is fixedly connected with the rotating rod The rotating gear rotates and meshes with the tooth grooves to move linearly along the scanning frame. At the same time, the mobile base is used to perform automatic scanning flaw detection. The scanning flaw detection effect is good. By setting the cleaning component and the coupling agent application component, the flaw detection effect is guaranteed.
Description
technical field [0001] The invention relates to the technical field related to ultrasonic flaw detection, in particular to an automatic flaw detection device and method based on ultrasonic technology. Background technique [0002] Ultrasonic flaw detection is a method for inspecting parts defects by using ultrasonic energy to penetrate deep into the metal material and pass from one section to another section, reflecting at the edge of the interface to inspect parts defects. Inside 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. According to these pulse waveforms, the position and size of the defect can be judged. , without damage, and accurately detect, locate, evaluate and diagnose various defects (cracks, inclusions, folds, pores, sand holes, etc.) inside the workpiece, and are widely used in manufacturing, iron and steel metallurgy, m...
