Universal device for determining the stiffness characteristics of the blades for bending in the thrust plane

摘要

FIELD: machine building.SUBSTANCE: invention relates to determining the stiffness characteristics of a blade for the purpose of controlling the quality of blades in a batch production and can be used to determine the stiffness characteristics of complex parts in various industries. Universal device for determining the stiffness characteristics of blades for bending in the plane of traction contains a curvature meter, consisting of a rigid beam with fixed and one movable measuring supports, measuring wheel, an electronic digital indicator, a bracket connecting the rigid beam by means of rollers with a frontal base surface of the blade, an information transfer unit from the measuring wheel and the electronic digital indicator to the computer device.EFFECT: technical result: increasing the accuracy of measurements by ensuring the repeatability of the trajectory of the movement of a rigid beam.1 cl, 2 dwg
