Abstract: The invention relates to a joining unit (10, 40) for an articulated arm robot (12, 44) for joining a component (24, 58) with a joining element (28, 60) by applying an axial force. The joining unit (10, 40) comprises a base element (14, 42) for connecting to an articulated arm robot (12, 44). The base element (12, 42) is connected to an advancing unit (13, 46), which can be moved relative to the base element (14, 42) in an axial direction in and against a setting direction. The advancing unit (13, 46) is connected to a setting device (16, 54), which can be moved together with the advancing unit (13, 46). Furthermore, a pressure piece (26, 50) mounted for movement relative to the advancing unit (13, 46) in and against the setting direction is connected to the advancing unit (13, 46) by means of a coupling unit (17, 48).

Abstract: A device for supplying and positioning fixing elements which includes, a chuck provided with two spring loaded clamping jaws that hold one fixing element therebetween for further processing, wherein the clamping jaws are operatively associated with an actuating element that extends between the clamping jaws, the actuating element being provided in an axial direction with a narrow section and two neighboring extension sections. The actuation element is connected to an axial slide for axially moving the actuation element and to open and close the chuck by forcing the camping jaws apart, releasing the fixing element for processing when the chuck is opened.

Abstract: The invention relates to a connecting element (1) for a friction-welded connection for connecting at least two panel-like components (8,9), comprising a rotating and pressurised mandrel (2, 13), the length of which is adapted to the thickness of the upper component(s) (7, 8) in order to penetrate the upper components(s) (7, 8), and which has a polygonal noncircular profile having rounded corner regions (5a, 5b). The noncircular profile has a thread-like design and has a pitch, the length of which is shorter than a complete thread turn.
