Abstract:
A head for the linear dimension checking of mechanical pieces, comprising a casing, that defines a longitudinal geometric axis, an arm-set, movable with respect to the casing, a feeler, coupled to movable arm-set, for touching the piece to be checked, a bias device, arranged between the casing and the movable arm-set, a detecting device, coupled to the casing, including a movable element, and a transmission device, between the movable arm-set and the movable element of the detecting device, including a wire, substantially rigid in said longitudinal direction but flexible in the directions perpendicular to the longitudinal direction, the wire having a first end coupled to the movable arm-set and a second end for cooperating with the movable element of the detecting device, the bias device being arranged in such a way that it urges the movable arm-set into contact with the casing and does not apply a compressive stress onto the wire of the transmission device.
