Abstract
A device for measuring the straightness of a rod-like work piece includes a support for the rod-like work piece. The support has multiple sections, each of which has a support surface. At least one force sensor is provided to measure the force applied by the work piece onto the support surface in a direction that extends essentially transverse to gravitational acceleration.
Claims20
A device for measuring a straightness of a rod-like work piece comprising:
- a beam;
- at least two support sections attached at different points of the beam, each of said at least two support sections including:
- a support surface configured to support a portion of the rod-like work piece;
- and a first sensor configured to measure a force that is applied by the rod-like work piece onto the respective support surface in a direction essentially transverse to a direction of gravitational acceleration;
- wherein the support surface of each of said at least two support sections is disposed on a piston rod within a cylinder, wherein the piston rod is configured to be displaced in a direction essentially opposite to the direction of gravitational acceleration by provision of compressed air to the cylinder.

A method for measuring a straightness of a rod-like work piece, comprising:
- placing the rod-like work piece onto at least two support surfaces of at least two support sections attached at different points to a beam;
- measuring, by a first sensor coupled to each of the at least two support surfaces, a force applied by the rod-like work piece to each of the at least two support surfaces in a direction essentially transverse to gravitational acceleration;
- wherein measuring the force applied by the rod-like work piece to each of the at least two support surfaces comprises measuring the force applied by the rod-like work piece to each of the at least two support surfaces in the direction essentially transverse to the direction of gravitational acceleration and unequal to the longitudinal direction of the rod-like work piece.
