Abstract
A head for the linear dimension checking of mechanical pieces, including a casing that defines a longitudinal geometric axis, an arm--set movable with respect to the casing, a feeler coupled to the movable arm--set for touching the piece to be checked, a biased device arranged between the casing and the movable arm--set for urging the movable arm--set into contact with the casing, 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. In order to reduce the frictions and improve the repeatability of the head, the transmission device includes a wire substantially rigid in a longitudinal direction but flexible in the direction perpendicular to the longitudinal direction. The wire has a first end coupled to the movable arm--set and a second end for cooperating with the movable element of the detecting device.
