ABSTRACT:
The invention contemplates a pneumatically driven piston as a preloading device, continuously urging the movable part (11) of a probe head into precise seating engagement with its fixed bearing (10), (12) in the housing of the probe head. The piston is movable in a cylinder (4) that is supplied with variable regulated pressure determined by a controlled regulating valve (16). Different contacting forces can be automatically and rapidly adjusted by the control system (18) of a coordinate-measuring machine to which the probe head is mounted, and the probe head can be tared to compensate for the different individual weights of successively different probe pins that are used in a given program of multiple-point coordinate measurements on a workpiece.
