Apparatus and method for measuring the geometry of the inner wall of bores

摘要

Apparatus for measuring the geometry of the inner wall of bores, boreholes or passages, possibly with countersinking, in particular for screw, pin or rivet joints of workpieces, comprising at least one measuring against the inner wall optical sensor, via a feed / rotation unit in the Borehole is insertable and rotatable, wherein an auxiliary object is provided with a passage which comes to rest on the surface of the workpiece and through the passage of the sensor immersed in the countersink and / or bore, characterized in that the inner wall of the auxiliary object is structurally dependent and the sensor scans through this structure during its advancing movement through the auxiliary object.
