Apparatus for measuring geometrical dimensions and/or errors on a mechanical part

摘要

Apparatus for measuring geometrical dimensions and/or errors on a mechanical part which includes a base, first and second supports, measuring devices, a first activating device coupled with the second support to control relative displacement between the two supports in order to cause feelers to cooperate with respective portions of the part, a locking device supported by the base to lock the part during measurement, a second activating device adapted to cause relative movement between the part and the measuring devices to permit feelers to explore respective portions of the part, a processing device to process signals supplied by transducers during the exploration of feelers on the part, thrust arms associated with the first support to support the part, first reference elements associated with the second support to cooperate mechanically with the part and push it towards the first support after the action of the first activating device overcomes the action of the thrust arms, second reference elements associated with the second support to cause the stopping of the first activating device at a first relative position of the supports, a micro switch and a control solenoid valve connected to the locking device to control the locking of the part when the first relative position of the two supports is reached and a seat and piston adapted to cause the loosening of the first reference elements from the part to permit relative movement between the part and the measuring devices and the consequent effecting of the measurements.
