Abstract:
1. Multicoordinate sensing measuring device, comprising: a) a housing; b) a sensing lever being spring-pretensioned in a resting position that can be displaced relative to the housing in the direction of a measuring axis and is guided by means of a universal joint such that it can be turned to all sides relative to the housing around a pivoting point located on the measuring axis and having a sensing arm protruding from the housing whose free sensing end defines a sensing reference point located on the measuring axis, in the resting position of the sensing lever; c) a connecting piece guided on a guide surface arrangement of the housing displacably in the direction of the measuring axis; d) a linkage that couples the sensing lever with the connecting piece and carries the connecting piece along in the direction of the measuring axis when the sensing arm is displaced in the direction of the measuring axis as well as when the sensing arm is deflected around the pivoting point; and e) a measuring device which detects the position of the connecting piece relative to the housing and wherein the connecting piece and the guide surface arrangement of the housing have bearing surfaces for balls of a ball bearing-arrangement where the bearing surface of at least one of the connecting piece and the housing can be deflected elastically transversely to the bearing surface and holds the balls clamped between the bearing surfaces without play.
