Abstract
A device for measuring edge and rounding features on a piston ring includes a planar support element for the piston ring, a stop operatively connected thereto for bearing defined piston ring sections thereon, and a measuring unit, which is disposed at a predefinable angle with respect to the support element or the stop.
Claims7
A device for measuring edge and rounding features on a piston ring, comprising:
- a planar support element having an outer planar surface configured to support a piston ring lying flat on said outer planar surface at a first ring side face;
- a stop operatively connected to the planar support element to bear against a running surface of the piston ring, the running surface being different from the first ring side surface;
- a measuring unit which is disposed at a predefinable angle with respect to the support element or the stop;
- wherein the measuring unit is disposed beneath the outer planar surface of the planar support element;
- and
- wherein, on the stop side, the support element has a recess via which running-surface edge features and rounding features of the piston ring lying on said outer planar surface are measured;
- and
- wherein the measuring unit is arranged beneath the support element at an angle of 45% relative to the plane of the support.
