FIELD: physics.
SUBSTANCE: invention relates to means of controlling the accuracy of manufacturing an article, mainly to devices for controlling the displacement of a helicopter rotor blade in the plane of rotation and plane of rotation. Device comprises base with face table and retainer, on faceplate there is housing with lower and upper jaws, on base hollow shaft is mounted on bearings, inside of which there is pin with coupling and a slider configured to transfer the movement from the pneumatic drive to the upper clamping jaw via a lever arranged in the body. Clamping jaws are equipped with pins pressed into their clamping surfaces.
EFFECT: technical result consists in improvement of accuracy of helicopter rotor blade escape measurement, increase of labour productivity and improvement of operating conditions.
