Patent ID: 8601704

Claim:
An apparatus for measuring and checking a mechanical piece comprising: a support and protection frame with a hollow handle defining a longitudinal axis; a position transducer with a stationary part that is housed in the handle and is stationary with respect to the handle and a movable part that is movable along a substantially longitudinal direction; a probe, connected to the support and protection frame, which includes at least one movable feeler adapted for contacting the mechanical piece to be checked, and a transmission mechanism having a stem and a transmission system adapted to transform movements of said movable feeler into longitudinal movements of the stem, the stem being adapted to cooperate with the movable part of the position transducer and to transmit said longitudinal movements to said movable part of the position transducer; and a coupling mechanism for connecting the probe to the handle with transversal reference surfaces adapted to cooperate with reference surfaces of the probe for defining the longitudinal position of the probe with respect to the handle, said coupling mechanism being fixed to the support and protection frame and including locking portions with a modifiable radial arrangement adapted to cooperate with the probe and a clamping element adapted to control the radial arrangement of said locking portions for locking and unlocking the probe to the coupling mechanism.
