Test device for a plurality of identical workpieces with reference to their dimensional stability at specific reference points

The invention relates to a test device for a plurality of identical workpieces with reference to their dimensional stability at specific reference points. The test device has a guide sleeve with a large, disc-shaped collar which can be moved on all sides free from play in a horizontal plane. Guided free from play in the guide sleeve is a sleeve which can be mounted with its prod on the reference points of the workpiece. Clamped to the sleeve in order to determine the position of the reference point is a first dial gauge, which is supported on the end face of a measurement ring moving along with the guide sleeve. A further dial gauge is pivotably mounted in a horizontal plane and touches the cylindrical reference surface, located on the outer circumference, of the measurement ring. By pivoting this further dial gauge around, the extent of the excentricity of the reference point can be determined with respect to its normal position and, as the case may be, the direction of the excentricity ...
