Scanning detection device for portable cylindrical ferromagnetic components

Abstract

The invention provides a scan detection apparatus for portable cylindrical ferromagnetic members. The apparatus comprises a supporting leg mechanism, a support chassis mechanism, a rotating platform mechanism, a telescopic arm mechanism and a probe array mechanism, wherein the supporting leg mechanism comprise a plurality of supporting legs, top of the supporting legs can be detachably fixed under the support chassis mechanism; an annular chassis of the support chassis mechanism is fixed with a plurality of support columns on the surface, a central position is fixed with a motor, tops of the support columns movably support an annular platform of the rotating platform mechanism; a lower surface of the annular platform of the rotating platform mechanism is provided with an annular groove corresponding to the support columns, a rotating shaft top of the motor is in a fixed pin connection with the center of the annular platform, an upper surface of the annular platformis fixed with one end of the telescopic arm mechanism; an end of the connecting arm of the telescopic arm mechanism is connected with a probe connecting rod, a bottom end of the probe connecting rod is fixedly connected with the probe array mechanism; the probe array mechanism comprises a probe body, and inside of the probe body is provided with a sensor groove. Therefore, the detection of cylindrical ferromagnetic members is relatively accurate and rapid.

Description

technical field [0001] The invention proposes a non-destructive testing device, in particular relates to a scanning detection device for a portable cylindrical ferromagnetic component which belongs to the technical field of mechanical engineering and is mainly used for external stress concentration or micro-crack detection of a large cylindrical ferromagnetic component . Background technique [0002] In the 1990s, Russian scholar Dubov proposed a metal magnetic memory detection technology. The physical basis is spontaneous magnetization, magnetomechanical effect, magnetostrictive effect, etc. The basic principle is based on the distribution of magnetic field leakage on the surface of metal components under the action of the geomagnetic field. The information determines the stress distribution of the metal components, thereby judging the early damage of the metal components. It has been proved that the magnetic memory detection technology is an effective new non-destructive ...
