Abstract
A gauge for checking linear sizes of mechanical parts including a handle, a nose-piece, an integral body defining two movable arms and fulcrum devices for rotational displacements of the arms, and a support plate coupled to the handle, the nose-piece and the integral body. The support plate has the form of a ring plate with two parts protruding towards the interior for defining two reference surfaces adapted to limit the opening stroke of the movable arm.
Claims12
A gauge for checking linear sizes of mechanical parts, comprising:
- a support;
- an integral member including a first section coupled to the support, two resiliently flexible sections connected to the first section and defining relevant fulcrum devices;
- two further sections, each defining a relevant movable arm, connected to the flexible sections for rotation movement about the relevant fulcrum devices;
- two feelers coupled to the movable arms, respectively, for contacting the part to be checked;
- and transducer means coupled to the movable arms for providing a signal responsive to the mutual position of the movable arms, the transducer means including two transducer parts coupled to the movable arms, respectively, each transducer part and each feeler being coupled to the relevant movable arm on the same side with respect to the relevant fulcrum device, wherein the gauge further includes a protective nose-piece substantially housing the movable arms, said support being substantially a plate defining first and second sides and at least a through hole, the moving arms passing through the plate.
