Abstract

The invention discloses an ultrasonic automatic detection system and detection method of a workpiece with clearance gridding-shaped multi-slope curve surfaces. The system comprises an ultrasonic wave flaw detector, a scanner as well as an industrial control computer, wherein a probe of the ultrasonic wave flaw detector is installed on a five-freedom-degree scanning support. Aiming at the problems that in the prior art, only the single curve surface can be detected, and the detection difficulty is high, an ultrasonic technique and a modeling technique are fused, and the automatic detection of a module with clearance gridding-shaped multi-slope curve surfaces is realized; the boundaries of the gridding-shaped multi-slope curve surfaces are recognized automatically by utilizing the ultrasonic detection and online real-time regulating technique on the basis of modeling, so that the probe is always vertical to the surface of the workpiece, thereby guaranteeing the authenticity, precision and reliability of the ultrasonic detection result; due to the integration of the ultrasonic wave technique, the modeling technique, the ultrasonic imaging technique and the ultrasonic wave automatic detection technique, the boundary recognition of a curve surface module is clear, the detection result is precise and reliable, the automation degree is high, and the man-machine interaction interface is friendly.

Description

technical field [0001] The invention relates to the inspection field of shielded-clad beryllium-copper welded parts, in particular to an ultrasonic automatic detection system and a detection method for workpieces with a grid-shaped multi-slope curved surface with gaps. Background technique [0002] In the field of automatic ultrasonic flaw detection, the relatively advanced technology in the prior art can only perform ultrasonic testing on non-grid multi-curved workpieces.
