Abstract

The invention discloses a solid shaft ultrasonic synthetic aperture focusing detection device and an imaging method for high resolution automatic ultrasonic detection imaging of a solid shaft. The detection device includes a probe frame component and a controller assembly, and is used for controlling the automatic positioning and axial movement of a probe. The imaging method is used for synthetic aperture focusing imaging under a polar coordinate system in the shaft. The technical effects of the invention lie in that the detection device can adapt to automatic ultrasonic detection of solid shafts with different diameters, realizes axial and radial positioning of defects, and improves the detection efficiency and scope; and the synthetic aperture focusing imaging method of the polar coordinate system in the shaft provided by the invention can solve the problem of low imaging resolution in traditional single probe ultrasonic detection of the solid shaft, and improves detection precision.

Description

technical field [0001] The invention relates to an ultrasonic detection device and an imaging method, in particular to an automatic ultrasonic detection device of a solid shaft and a synthetic aperture focusing imaging method. Background technique [0002] Solid shafts are widely used as bearing parts in the industrial field. Due to the influence of complex working environments such as high temperature and high pressure during the manufacturing process or during operation, defects such as inclusions, pores, and fatigue cracks will occur inside the solid shaft. If these defects cannot be detected If it goes out, it will cause the solid shaft to break during service and cause a safety accident. [0003] Ultrasonic testing has the advantages of wide detection range, high detection efficiency, high flaw detection sensitivity, low detection cost and harmless to human body, etc. It is widely used in industrial detection. The current conventional detection method for solid shafts ...
