ABSTRACT:
A gauge for checking linear dimensions of mechanical parts comprises a support, a movable gauging arm, a transducer coupled to the movable arm and the support, and a helical spring defining a longitudinal geometrical axis and having a first end in abutment with the movable arm and the second end in aubtment with a movable element of an adjustment device for adjusting the force applied by the spring to the gauging arm, the device comprising a screw coaxial to the spring and arranged within the spring coils, and a stanchion which controls a translation movement of the movable element along an axis substantially coinciding with the spring axis, translation movement of the movable element changing the axial length of the spring and, consequently, the force it applies to the gauging arm.
