DEVICE FOR CONTROL OF SURFACE SHAPE Russian patent published in 1995 - IPC

FIELD: measuring instruments. SUBSTANCE: lasers 1 and 2 with parallel optical axes are installed coaxially in hollow rods 9 and 10 secured with a provision for axial motion in casing 17 which carries three supports 18 two control line retainers 20 and 21, and unit 19 for adjusting the distance between the axes of lasers 1 and 2. The axle of each joint 11 and 12 coincides with reflecting surface of mirrors 15 and 16 on swinging carriages 13 and 14 and is perpendicular to the optical axes of lasers 1 and 2. EFFECT: higher accuracy and efficiency in control of inscribability of mechanization members into wing contour of an aircraft achieved by ensuring unity of bases when controlling various sections of the object with simultaneous control in two or more sections of mechanisms. 2 dwg
