Verfahren für das automatische Verschrauben von zwei Bauteilen und Stiftschraube und Überwurfmutter zur Durchführung des Verfahrens

摘要

The method for automatic screwing together of two components (2) uses a torque controlled pulling technique. It has an assembly apparatus (1) and a screwed connecting element (4) for joining the components. The connecting element is first tightened by the controlled rotation of the screws. The element is then pulled tight up to a pre-determined end torque value. The connecting element has two threaded sections (5,6) which have different pitches to each other. Each threaded section engages with one of the components to be screwed together.
