ABSTRACT:
A gauge for the dimensional checking of mechanical pieces comprises an outer casing, an armset fixed to the casing and having a gauging arm movable along two opposite directions, a feeler carried by the gauging arm for contacting the piece to be checked, a limiting device for adjustably limiting the displacements of the gauging arm along the directions, a spring cooperating with the gauging arm for urging the feeler against the piece, and a device for adjusting the force applied by the spring. The limiting device includes a member, fixed to the casing, which defines a first abutment surface for limiting the displacements of the gauging arm along one of the directions, and a screw passing through the hole of the gauging arm. The screw is coupled to the member and defines a second abutment surface, adjustable with respect to the first abutment surface. The device for adjusting the force applied by the spring has a movable element cooperating with the member for permitting adjustment of the force applied by the spring while preventing torsion of the spring.
