A method and device for determining an orientation of two rotatably mounted machine parts, an alignment of two hollow cylindrical machine parts or for checking a component on straightness along a longitudinal side

摘要

The present invention relates to a method and a corresponding device for determining an orientation of two rotatably mounted machine parts, an orientation of two hollow cylinders - of the cone-shaped machine parts or for testing the components on straightness along a longitudinal side,with a first measuring unit with a light source for emitting a light beam is expanded in a planeand a second measuring unit with an optical detector unit, which comprises two, arranged parallel to one another, there is line sensorswith an evaluating unit, in order to provide a of the flat expanded light beam generated light pattern for determining a misalignment of the axes of the machine parts relative to each other, or, if appropriate, to evaluate a straightness of the component, wherein for determining the impact points of the flat expanded beam of light onto the line sensors are used.
