Apparatus for checking dimensions and shape of a mechanical piece comprising a stationary support, a movable support connected to the stationary support in a removable way including a mechanical armset connected thereto, and one or more position transducers coupled to power supply and processing electrical circuits. The armset comprises one or more arms, each carrying a feeler, and one or more fulcra enabling movements of the arm(-s) with respect to the movable support. Each transducer includes two parts facing each other and arranged at a predetermined mutual distance. One part is connected to the movable support, more specifically to one of the arms of the mechanical armset, and the other part is connected to the stationary support, only one of the two parts of the transducer being coupled to the electrical circuits. Thanks to the particular configuration of the transducer and the modularity of the mechanical structure of the apparatus, it is possible to remove the movable support without removing also the stationary support and substitute it with a movable support suitable for the dimensions to be checked. According to different embodiments of the apparatus of the invention, it is possible to check internal or external dimensions and shape of a mechanical piece, and determine the position of the central axis of the piece. |
