ABSTRACT:
In a multi-coordinate measuring machine, a contact pin is movable relative to an upper part of a measuring head, in the X, Y and Z directions. The contact pin must be mounted so as to be displaceable from its zero position, and blockable in position in each of these directions. To simplify the construction, the mechanism for displacing and blocking the movements of the pin are combined in the form of an electrodynamic transducer for each of the three directions. The transducer is formed of a pair of aligned coils which are each associated with a permanent magnet.
