However, at present, eddy current testing is mainly manual testing, and the testing personnel hold probes to detect cracks, which are only aimed at static cracks
As researchers have higher and higher requirements for monitoring cracks that are expanding, this kind of manual static crack detection can no longer meet the requirements

The invention relates to an automatic tracking system for cracks, and particularly relates to an automatic tracking system and an automatic tracking method for cracks generated on the surface of a metal material. The automatic tracking method disclosed by the invention comprises the following steps of: detecting the cracks by virtue of a detection coil installed on a combined manipulator which is controlled by a computer, judging whether the cracks exist on a detection route by the computer according to a signal fed back by the detection coil, performing scanning, expanding and extending detection according to detection information, keeping the detection coil always pointing to the tips of the cracks, and then realizing the automatic tracking on the crack expanding on the surface of metal. Via the automatic tracking method disclosed by the invention, the eddy-current detection is not limited to be within the range of detection on static cracks any more, and reliable detection data are provided for scientific research personnel; and the detection on the cracks can be automatically finished by a machine in dynamic crack monitoring with a certain risk, so that the safety of the personnel is protected.
Description
technical field [0001] The invention relates to an automatic tracking system for cracks, in particular to an automatic tracking system and tracking method for cracks on the surface of metal materials. Background technique [0002] At present, eddy current testing is one of the commonly used non-destructive testing methods for crack detection on the surface of metal materials and parts. This detection has the advantages of high sensitivity. However, at present, eddy current testing is mainly manual testing, and testing personnel hold probes to detect cracks, which are only aimed at static cracks. As researchers have higher and higher requirements for monitoring cracks that are expanding, this kind of manual static crack detection can no longer meet the requirements. Contents of the invention [0003] The purpose of the present invention is to provide a system for automatically tracking the cracks in the expanding state on the metal surface in view of the deficiencies in th...
