<p>A checking apparatus, for example a plug gauge, for checking diameters and/or geometrical features of mechanical parts includes a support structure ( 1 ) and checking means ( 20,21 ) coupled to the support structure, with mutually movable feelers ( 36 ) for contacting the surface of the part and transducer means for providing electrical signals. The support structure includes at least two studs ( 11,12 ) that achieve a guide along a longitudinal axis, and the checking means are coupled to the studs in a removable and adjustable way along such longitudinal axis. Several checking means can be coupled to the studs. A particular embodiment foresees three flanked studs and checking means coupled to pairs of adjacent studs. An adapting system allows the feelers to self-center on the part to be checked, for example the surface of a hole.</p> |
