Abstract:
An axial movement linear gauge includes a support and protection structure (21) that defines a longitudinal axis, a spindle (11) movable along the longitudinal axis with an external surface on which a longitudinal groove (12) is achieved, a feeler (14), a position transducer (32), a thrust device (36) for thrusting the spindle with respect to the support and protection structure, guide devices (22) for guiding movements of the spindle along the longitudinal axis with respect to the support and protection structure, and an antirotation system for preventing rotations of the spindle about the longitudinal axis that includes antirotation elements (50,51), stationary with respect to the support and protection structure, cooperating with the longitudinal groove. The guide devices can be integrally embodied with a locking element that cooperates with the support and protection structure for defining an operative position of the guide devices with respect to the support and protection structure.
Abstract:
A plug gauge (1) includes a support and protection system that defines a longitudinal axis with a handle (2) closed by a cap (13) that includes electronic devices for the wireless transmission of electrical signals representative of a dimension to be checked, and a probe (6) including a measuring armset coupled with a transducer for generating electrical signals. The probe is connected to the cap of the handle by means of an interface element (8) that includes mechanical references to prevent rotations of the probe with respect to the handle about the longitudinal axis.
