ABSTRACT:
The measuring apparatus comprises a base plate member including a rotatable measuring object receiving station adapted to rotatably receive e.g. a tool to be measured. Besides the receiving station, a guiding column is arranged having a guiding rail along which a measuring carriage is movable upwardly and downwardly. The carriage is provided with a horizontally displaceable measuring rail, an end portion thereof being equipped with a measuring calliper assembly. This assembly includes a measuring calliper with a calliper head which may be brought into contact with the tool to be measured. The calliper head is displaceable with regard to a calliper portion fixed to the end portion of the measuring rail. A force acting on the calliper head in horizontal direction (e.g. towards the right) causes the same displacement of the calliper head as a force acting on the calliper head in vertical direction (e.g. upwardly). The displacement is determined by means of a measuring gauge. With the measuring apparatus of the invention, objects may be measured in three dimensions without the need to constructionally change or readjust the apparatus.
