Airbag tool fatigue ray nondestructive detection device and automatic detection method thereof

Abstract

The invention discloses an airbag tool fatigue ray nondestructive detection device and an automatic detection method thereof. The airbag tool fatigue ray nondestructive detection device comprises a ray nondestructive detection box, an in-place cylinder type guide rail and a movable lifting frame; the ray nondestructive detection box comprises a ray emitting module, an image receiving plate, a detection box workbench, a protective shell and an image processing system; the protective shell serves as a carrier of the ray nondestructive detection box and is used for fixing the ray emitting module, the image receiving plate and the detection box workbench; and the ray nondestructive detection box is connected with the in-place cylinder type guide rail or the movable lifting frame, so that an airbag tool is adjusted in a ray range to obtain a state image of a metal material structure of the airbag tool under two working modes of detection or off-line detection, and then fatigue characteristics are extracted to complete nondestructive testing. According to the airbag tool fatigue ray nondestructive detection device and an automatic detection method thereof, the fatigue damage condition of the airbag tool can be qualitatively and accurately detected and analyzed, and visual images can be stored for a long time.

Description

technical field [0001] The invention relates to the field of non-destructive testing of machine tools, in particular to an airbag tool fatigue ray non-destructive testing device and an automatic testing method thereof. Background technique [0002] The key structure of the airbag tool is the spherical crown part, and its "sandwich" structural feature, that is, the inner and outer layers are composed of rubber materials, and the middle is made of metal materials, and it is subjected to repeated tensile and pulsating stress loads during its processing. Therefore, the damage generated during the processing will accumulate and lead to plastic deformation of the metal layer, and the plastic deformation will become more and more serious as time goes by, so the fatigue damage of the airbag tool during the polishing operation only reflects the early stage of traditional fatigue damage. The degradation stage of mechanical properties, the initial and accumulation stages of damage, tha...
