Abstract
A measuring device including a moveable measuring probe and sensors coupled to the measuring probe for providing position data of the measuring probe. The measuring probe is coupled, by a cord or a wire, to a first sensor for measuring a length or change in length of the cord or wire, and to a second sensor for measuring an angle or angular displacement of the cord or the wire. The obtained position data can be graphically represented and/or used for driving an automatic machining apparatus for producing a product corresponding to the measured data.
Claims20
A measuring device comprising:
- a movable measuring probe;
- and
- first and second sensors, coupled to the measuring probe, configured to provide position data of the measuring probe;
- wherein the measuring probe is coupled, by a cord or a wire, to the first sensor to measure a length or change in length of the cord or the wire, and to the second sensor to measure an angle or angular displacement of the cord or the wire, which second sensor is coupled to an elongate, rotatably supported arm, in a longitudinal direction of which the cord or the wire engages the arm,
- wherein the arm is spatially rotatably supported at a first end by a sphere or ball type bearing, and the second sensor is configured to measure rotation of the arm in two degrees of freedom.
A device for graphically representing measured position data, comprising:
- a measuring device having a movable measuring probe;
- and
- first and second sensors, coupled to the measuring probe, configured to provide position data of the measuring probe,
- wherein the measuring probe is coupled, by a cord or a wire, to the first sensor to measure a length or change in length of the cord or the wire, and to the second sensor to measure an angle or angular displacement of the cord or the wire, which second sensor is coupled to an elongate, rotatably supported arm, in a longitudinal direction of which the cord or the wire engages the arm,
- wherein the arm is spatially rotatably supported at a first end by a sphere or ball type bearing, and the second sensor is configured to measure rotation of the arm in two degrees of freedom.
A machining apparatus for automatically producing objects based on predetermined measuring data, comprising:
- a measuring device including a movable measuring probe and first and second sensors, coupled to the measuring probe, configured to provide position data of the measuring probe,
- wherein the measuring probe is coupled, by a cord or a wire, to the first sensor to measure a length or change in length of the cord or the wire, and to the second sensor to measure an angle or angular displacement of the cord or the wire, which second sensor is coupled to an elongate, rotatably supported arm, in a longitudinal direction of which the cord or the wire engages the arm,
- wherein the arm is spatially rotatably supported at a first end by a sphere or ball type bearing, and the second sensor is configured to measure rotation of the arm in two degrees of freedom.
A method for measuring an object by a measuring device comprising a movable measuring probe that is coupled, by a cord or wire, to first and second sensors configured to provide position data of the measuring probe by measuring a length or change in length of the core or the wire, and an angle or angular displacement of the cord or the wire, wherein the measuring probe is positioned on a circumference of the object to be measured, wherein an angle or angular displacement of the cord or the wire is measured in two degrees of freedom from an elongated arm spatially rotatable supported at a first end by a sphere or ball type bearing, in a longitudinal direction of which the cord or the wire engages the arm.
