The invention discloses an insulating bearing ceramic coating defect detection device and detection method, and belongs to the field of optical scattering defect detection. According to the invention, a plurality of receivers and photoelectric detectors are adopted to simultaneously carry out defect surface scattering light intensity detection, under the cooperative control of a stepping motor and a mobile workbench, complete scanning detection of a ceramic coating of an insulating bearing is realized, and final detection signals are transmitted to a control terminal for analysis and a detection result is generated. Compared with the prior art, various defects such as cracks, holes and loose area collapse pits of the ceramic coating of the insulating bearing can be effectively detected, the detection precision is high, the device is simple, the detection efficiency is high, and the method is suitable for occasions needing rapid detection of surface defects of an insulating bearing.
Description
technical field [0001] The invention belongs to the field of optical scattering defect detection, and in particular relates to a detection device and a detection method for ceramic coating defects of insulating bearings. Background technique [0002] The insulated bearing adopts a special spraying process, and the outer surface of the insulated bearing is sprayed with high-quality ceramic coating, which has good insulation performance, can avoid the electric corrosion effect of the induced current on the bearing, and improve the service life of the bearing. During the preparation of insulated bearings, due to factors such as spraying process defects, environmental changes, and process parameter fluctuations, various defects such as coating cracks, holes, and collapse pits in loose areas may occur in the ceramic coating. [0003] At present, there are few detection methods for ceramic coating defects of insulated bearings. Most of them are surface defect detection methods for...
