摘要： A method for supplying, positioning and processing fixing elements using a transport means which moves the fixing elements from a starting position to a processing position whereby the individual fixing elements are introduced into a chuck provided with two clamping jaws, are held by the clamping jaws in an engaging position and, once the chuck has been positioned, are taken up from this position by a driving element and the chuck presses them against a locating device and a connection is made to a component part by the driving element when the chuck is opened, wherein the upward motion of the chuck, while feeding the fixing element to the locating device, prevents the supply of further fixing elements to the chuck.

摘要： 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). The invention is distinguished in that the coupling unit (17, 48) comprises a blocking unit (18, 56), which, starting from a predefined axial blocking position, prevents motion of the pressure piece (26, 50) relative to the advancing unit (13, 46) against the setting direction so long as the advancing force is less than the set blocking force. The blocking unit comprises a release device (20, 62), by means of which the relative motion of the pressure piece (26, 50) against the setting direction is enabled.

摘要： The invention relates to a connecting element (10, 20, 30, 50) for producing a component connection (70) of two components (72, 74; 92) lying against each other by means of the connecting element (10, 20, 30, 50), which is welded to the lower layer (74)—the base layer—by friction, wherein the connecting element (10, 20, 30, 50) has a shaft (18), which has a shaft segment (14) and a head (12) having a flat surface (20) lying on the top side of the head for transmitting the axial force, wherein a drive cutout (22, 32) is introduced into the flat surface (20) in order to transmit a torque. The invention is characterized in that a continuous diameter increase starting at an ascent level (A) on the shaft segment (18) to the bottom side of the head results, wherein the distance from the ascent level (A) to a head bottom-side level (K), which has the greatest distance from the shaft end, is less than half the difference between the head outside diameter and the shaft diameter at the ascent level (DA−DS)/2 (D2) and greater than a quarter of the difference between the head outside diameter and the shaft diameter at the ascent level (DA−DS)/4 (D1).

摘要： A switch arrangement for the selection of joining elements, which comprises a switch that comprises at least three supply points in which joining elements can be supplied to the switch in a position-oriented manner. Furthermore, an output point is provided where joining elements can be output in a position-oriented manner, the switch comprising a conveying element which has at least three receiving compartments each being adapted to receive a supplied joining element each at the supply point. A conveying element can convey the joining elements from a receiving position to an output position from the supply point to an output point, which is fixed relative to the supply points, and output.
