Abstract: The disclosure relates to a method for checking a rivet, the rivet being transported from a rivet filling station along a transporting path in the direction of a riveting machine during operation of the riveting machine. The method is characterized in that the rivet is measured on the transporting path for determining a rivet geometry of the rivet. The disclosure similarly relates to a corresponding measuring arrangement for checking a rivet.

Abstract: A manufacturing system for producing airplane structural components, including a drilling unit for producing bores in a material assembly made of at least two material plies for the purposes of inserting fastening elements and having a measuring unit for ascertaining geometry parameters for a previously produced bore. The measuring unit includes measuring electronics with an optical sensor element, a measuring optical unit and a measuring lance. The measuring unit produces an optical measurement beam that emerges from the measuring lance via the measuring optical unit and that is incident on a measurement point on the respective bore inner surface. A measurement movement between measuring lance and material assembly is provided in a measurement cycle and the measuring unit cyclically ascertains distance values to various measurement points at a scanning rate during the measurement movement and ascertains at least one geometry parameter for the respective bore from the distance values.

Abstract: The invention relates to a manufacturing system for producing airplane structural components, comprising a drilling unit (2) for producing bores (3) in a material assembly (4) made of at least two material plies (4a, 4b) for the purposes of inserting fastening elements, in particular rivet elements, and comprising a measuring unit (5) for ascertaining geometry parameters for a previously produced bore (3).

Abstract: The invention relates to a method for checking a rivet (1), the rivet (1) being transported from a rivet filling station (2) along a transporting path (3) in the direction of a riveting machine (4) during operation of the riveting machine (4). The method is characterized in that the rivet (1) is measured on the transporting path (3) for determining a rivet geometry of the rivet (1). The invention similarly relates to a corresponding measuring arrangement for checking a rivet (1).
