OPTOELECTRONIC DEVICE FOR MEASURING PARAMETERS OF BLADES

FIELD: measuring arrangements. ^ SUBSTANCE: device comprises unmovable base provided with the first cantilever, two carriages provided with drives controllable with a computer, pickup of linear movements, arrangement for mounting blade and first measuring channel connected with the computer. The first carriage is mounted on the unmovable base and is made for permitting movement parallel to the X-axis. The first measuring passage is defined by the optoelectronic head and units secured to the unmovable base, third carriage provided with an actuator controlled by a computer and pickup of linear displacements, second measuring channel, first and scone markers of the blade with actuating members controlled by a computer, arrangement setting the blade mounted on the first carriage and made for permitting rigid orientation of the blade in the vertical plane, second and third carriages arranged on the first and second cantilevers, respectively, and made for permitting movement parallel to the Z-axis, first and second markers of the blade, fiber optic heads of the first and second measuring channels arranged on the second and third carriages from the both sides of the study blade. The objectives of the fiber optic heads are mounted for permitting triangulation link of the photodetector with the sourced through the blade surface of the blade to be tested. ^ EFFECT: enhanced efficiency. ^ 6 cl, 7 dwg
