Abstract

The micrometer comprises a body (1) and a measurement head held for the purpose of measurement at the end of an arm (6). Three moving keys (23), composed of an end feeler (24), an elongate core (25) and a support piece (26) are inserted in longitudinal grooves made in the arm (6) and the body (1). Each key (24) is displaced radially by the combined translational and rotational movements of a smooth cone (27) and a helicoid conical slope (28) which are mounted coaxially on a rod (10), and on which the said key is held pressed by a circular spring (22). The rod (10) is controlled by a shaft (2) to which it is connected via a micrometric measurement screw (29) engaged in an internal thread of the body (1). By virtue of the use of the smooth cone for controlling the displacement of the feelers, the micrometer benefits from a large measurement capacity. This micrometer may be used for measuring bores of small diameter. <IMAGE>
