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:
Plug gauge (1;61) and checking system for checking dimensions and/or form deviation of a hole including: a main body (2; 62) which has a longitudinal axis and is adapted to be inserted into the hole; at least a feeler (7; 7', -67) which is mounted on the main body so as to be radially movable and is adapted for touching a surface of the hole to be checked; and at least a position transducer (4; 64) which is adapted for detecting the radial position of the feeler and has components that are independently supported by the main body, in particular a movable component (5; 65) mechanically connected to the feeler and a stationary component (6; 66) carried by the main body and coupled to the movable component.
