A method for regulating a device used for fixing aircraft airframe pieces in connection with assembly of airframe parts, where the device consists of a rig comprising a matrix of rails that can slide in such a way that a number of fixing elements attached to the rails can be positioned freely along three co-ordinates x, y, z in space within a given volume, where a manipulator grasps a fixing element after which the fixing element is moved by the manipulator to the given co-ordinate, and where the rails on which a fixing element is arranged is locked in relation to the rig by an automatic locking function initiated by the manipulator, thereby fixing the fixing element's position in space and the setting procedure is repeated for a predetermined number of fixing elements on the rig.
A method for regulating a device used for assembling aircraft airframe pieces, where the device comprises a rig comprising main rails that can slide parallel to each other alongside the rig along a first co ordinate x, and on each main rail a number of guide rails which can both slide parallel to each other along the main rail along a second co ordinate y, and axially along a third co-ordinate z, and with a fixing element at the end of the guide rail, where the method involves the following steps:
A device used for assembling aircraft airframe pieces, wherein the device comprises a rig comprising main rails that can slide parallel to each other alongside the rig along a first co-ordinate x, and on each main rail a number of guide rails which can both slide parallel to each other along the main rail along a second co-ordinate y, and axially along a third co-ordinate z, and at the end of the guide rail there is a fixing element, and wherein the guide rails are arranged in a carriage, where the carriage slides along the main rail by means of guides.
