Three dimensional coordinate measuring sensor for machines, has active portion remote from fixed portion and connection component between active and connection portions forming mechanical joint with one degree of freedom

摘要

The sensor has a portion fixed to an end (2,3) of a moving arm (1) and an active portion, remote from the fixing portion. A connection component exists between the active portion and the connection portion leading to the formation of a mechanical joint having one degree of freedom. The degree of freedom of the joint is either a degree of freedom in translation or rotation.
