ABSTRACT:
A probe head for coordinate-measuring instruments has a torsionally rigid, play-free and friction-free probe-suspension system which defines a three-dimensional coordinate system, wherein a probe pin is deflectable in all three directions in space. In order to be able to use the probe pin completely independent of its orientation, a separate taring device provides taring adjustment for each of the three coordinate axes in space. The taring device automatically sets the zero position of the suspension system in any orientation of the probe head, and for any change in orientation. In this connection, it is particularly advantageous to develop each taring device from two springs which are preloaded to act in opposition upon an element which is gravitationally deflected upon any change in probe-head orientation; to reach the zero position detected by an indicator, i.e., to effect the taring adjustment, provision is made for adjustment of the preload force of at least one of these springs.
