Probe deployment mechanism of measuring machine with isolated locator coupling

摘要

A probe deployment mechanism of a coordinate measuring machine provides for extending and retracting a probe. The probe is displaceable with respect to the actuator body connected to the measuring machine. A locator coupling secures the probe to the actuator body at the extended position for taking measurements. A drive coupled to the probe displaces the probe between the extended and retracted positions but at the extended position, the drive is releasable from the probe for kinetically isolating the locator coupling.

1. A probe deployment mechanism for a coordinate measuring machine comprising:
an actuator body arranged for connection to a measuring machine; a probe being displaceable with respect to the actuator body between extended and retracted positions; a locator coupling that is engageable in the extended position of the probe for constraining movement of the probe with respect to the actuator body; and a drive releasably coupled to the probe for displacing the probe between the extended and retracted positions so that in the extended position, the drive is kinetically isolated from the probe.
