Tight multidirectional measuring probe

Abstract

Abstract 1. A sealed multi-directional dimensional measuring probe comprising a probe rod (4) bearing at its free end a probe element (5) and continued at its other end by a transmission rod (6) which cooperates with a dimensional measuring pick-up element (12), and a casing (1), the probe rod (4) being situated solely outside the casing (1), characterised in that the wall of the casing (1) situated adjacent the probe rod (4) comprises an elastically deformable diaphragm (2) fixed in sealing-tight relationship to the body of the casing (1) and in that said diaphragm (2) forms the support for the system formed by the probe rod (4) and the transmission rod (6) so that any movement of the probe element (5) at the end of the probe rod (4) produces a displacement of the transmission rod (6), in that the co-operation elements between the transmission rod (6) and the pick-up element (12) comprise a spherical ball (11; 11a) and a corresponding seat (10; 10a) having a curved surface so shaped that the longitudinal movements of the pick-up element (12) linearly reproduce the multi-directional movements of the probe (5) at the free end of the probe rod (4).
