Measurement probe for use in coordinate measuring machines
A measurement probe for use in coordinate measuring machines, which measurement probe includes a base ( 1 ) connected with a coordinate measuring machine, a measurement tip ( 4 ) and a ball ( 5 ) arranged at the first end of the measurement tip ( 4 ). The measurement tip ( 4 ) is supported at its other end with the aid of at least three rigid supports ( 2 ) supported by the base ( 1 ), whereby the supports ( 2 ) are connected with the measurement tip by way of spherical connections and where the supports ( 2 ) can be displaced along their longitudinal directions relative to the base ( 1 ).
1. A measurement probe for use in coordinate measuring machines, said measurement probe comprises a base ( 1 ) connected with a coordinate measuring machine, a measurement tip holder ( 3 ) and a measurement tip ( 4 ) supported by this holder, characterized in that the measurement tip holder ( 3 ) is supported by the base ( 1 ) with the aid of at least three rigid supports ( 2 ), whereby the supports ( 2 ) are connected with the measurement tip holder ( 3 ) by means of spherical connections and where the supports ( 2 ) can be displaced along their longitudinal directions relative to the base ( 1 ) such that the angle of the measurement tip holder ( 3 ) relative to the base ( 1 ) can be changed, and in that the supports ( 2 ) are connected with the base by means of leaf springs ( 6 ) that are directed radially outwards from the base ( 1 ).
2. The measurement probe according to claim 1 , characterized in that driving means ( 8 ) are connected with the base ( 1 ) in order to interact with the supports ( 2 ) for maneuvering of the measuring tip holder ( 3 ).
3. The measurement probe according to claim 2 , characterized in that the driving means ( 8 ) comprises a coil ( 9 ) and an element ( 11 ) that can be moved within the coil, said element ( 11 ) is arranged to influence the outermost end of the leaf springs ( 6 ) and in this way the supports ( 2 ).
4. The measurement probe according to claim 3 , characterized in that the measurement tip ( 4 ) comprises a physical measuring tip ( 4 ) with a ball ( 5 ) arranged in the end of it.
5. The measurement probe according to claim 2 , characterized in that the measurement tip ( 4 ) comprises a physical measuring tip ( 4 ) with a ball ( 5 ) arranged in the end of it.
6. The measurement probe according to claim 1 , characterized in that the measurement tip ( 4 ) comprises a physical measuring tip ( 4 ) with a ball ( 5 ) arranged in the end of it.
