However, only one gripper chuck can be steered into the grab positions in each case, while the other gripper chuck is then located in the parking position outside a grab area on the component.

Abstract: A method and a system for applying a seal to the closure of an opening, in particular to a door of a motor vehicle, is provided. The application takes place in two stages. In a first stage, a seal, which is cut off from a continuous seal strip is placed with a stationary roll-on head on placing and pressing elements of a tensioning plate, which are moved past the roll-on head. In a second stage, the tensioning plate with the seal placed on the placing and pressing elements is guided to the closure of the opening and pressed here by means of the pressing elements on the bonding face of the closure of the opening. In general, this type of application takes place exclusively by mechanical means.

Abstract: A method for producing attached parts for a motor vehicle, for example doors, dampers, mudguards formed by internal (1) and external (2) sheets. The external sheet (2) is inward bent in the visible areas of the door or attached part, the sheet edges being practically parallel to the plane of attached parts in the invisible (not apparently visible) areas of the door or attached part. The internal sheet (1) is pushed against the external sheet (2) in a flanged area in such a way that a small accurately defined gap for laser welding is produced. The internal (1) and external (2) sheets are welded to each other in the form of an overlap joint in the opposite invisible areas, thereby compensating tolerances.

Abstract: A manufacturing plant, in accordance with one embodiment, includes a turntable, interchangeable pick-up, and clamping devices for assemblies at several working locations. The pick-up and clamping devices are assigned at least one processing robot, set up for joining operations, which performs the joining operations on the assemblies held by the pick-up and clamping devices. The turntables 1, 2 are assigned interchange stations, with which the pick-up and clamping devices on turntables can be replaced by others. The interchange stations are preferably designed as turntables with different storage locations for the pickup and clamping devices to be replaced. The different pick-up and clamping devices needed for processing various types of assemblies as well as grippers for the handling robots are introduced exclusively from outside in exactly the same way as the pre-fabricated parts being processed, if a change from one type of assemblies to another type is required.

Abstract: A support arm for a clamping and/or centering element of a gripper frame for holding three-dimensional components includes an adjustment mechanism, such as a ball that can pivot or a cylindrical pin that slide and rotate, held in a clamping and release unit with clamping jaws that can be radially clamped and are configured as shells engaging on opposing halves of the ball or the cylindrical pin and whose separation distance can be set by a means of adjustment. A radially directed compression force can be applied to the clamping jaws by a ring-shaped hydraulic force generator that is arranged about the jaws.

Abstract: A method provides for joining an outer sheet and an inner sheet, in particular of an attachment part of a motor vehicle body. On the visible sides of an attachment part, a welding or brazing seam is produced between a fold of an outer sheet and an inner sheet. The outer sheet is held in a bed, and the inner sheet is pressed against the fold on an inner side thus forming a joining groove. To ensure that during beam welding or beam grazing the inner sheet is held in position on the fold, it is prevented from moving away without clamping by stops on an outer side. These stops are disposed in a row along the welding or brazing seam and in dependence upon the progress of the joining procedure can be moved individually out of a path of a welding or brazing head.
