Abstract
(B3) Die vorliegende Erfindung betrifft ein Verfahren zum Erkennen einer fehlerhaften kraft- oder formschluessigen Verbindung, insbesondere einer Schraubverbindung, wobei zumindest zwei Elemente, die anfangs in einem kraft- oder formschluessigen Eingriff miteinander stehen, relativ zueinander derart bewegt werden, dass die Verbindung kraftentlastet wird und/oder der Formschluss zumindest teilweise geloest wird, wobei zumindest ein die Verbindung charakterisierender Parameter waehrend der Bewegung gemessen wird und mit einem Sollparameter verglichen wird, sowie eine derartige Vorrichtung zum Erkennen einer fehlerhaften kraft- oder formschluessigen Verbindung.
DE 102006047683 B3 UPAB: 20080421 NOVELTY - The method involves moving a screw (3) and a clamping section (1), and/or a counter piece (2) relative to each other and provided in force or form-fitting contact such that a screw connection is force-balanced and/or a form-fit is partially released. A torque or force characterizing the connection is measured as a parameter during a relative movement between the screw and the section, and/or the piece and is compared with a reference parameter. A friction force path or a friction moment path is determined between the screw and the clamping section, and/or the counter piece. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a device for recognizing a defective force or form-fitting connection i.e. screw connection. USE - Method for recognizing a defective force or form-fitting connection i.e. screw connection, by an on-screwing device. ADVANTAGE - The torque or force characterizing the screw connection is measured as the parameter during relative movement between the screw and the clamping section, and/or the counter piece and is compared with the reference parameter, thus automatically recognizing the defective force or form-fitting screw connection in a reliable manner during disassembling of the connection.
