DEVICE FOR PERFORMING VISUAL AMD MEASUREMENT INSPECTION OF INTERNAL CAVITIES

摘要

FIELD: non-destructive inspection. ^ SUBSTANCE: device has standard side-view endoscope, which has system for illuminating object and system for observing object provided with measuring scale. Device is additionally provided with bushing having linear and angular scales, which bushing is capable of translation and rotation about axis of symmetry of flange fastened to input opening of cavity to be controlled. Tube with optical system for laser illumination of object is mounted inside bushing; tube has microscopic laser and mirror. Tube is mounted in bushing for linear movement relatively endoscope in parallel to its longitudinal axis. Precision of measurement of sizes of objects disposed at long distances to surfaces to be controlled is improved. Measurement of coordinates of defect location on surfaces of object can be made with higher precision. ^ EFFECT: improved precision of measurement. ^ 3 dwg
