Abstract: The invention relates to a method and a device for installing door hinges on car bodies, whereby the actual opening width of the car door on the side frame receiving one or two car doors in the longitudinal car axis is touch-sensitively determined by means of a sensor in a direction X and the arrangement of the door hinges is adjusted in said direction X using a positioning system connected to the sensor by a cranking device, depending on the tolerance margin, which should be calculated so as to have at least vertically (direction Z) as uniform a slot width as possible once the car door is mounted.

Abstract: An edging device or hemming device is disclosed with a machine frame (1), an edging bed (2) which is positioned inside said frame where it is raised and lowered with an edging lift and/or a displacement lift. A plurality of edging jaws are provided, which can be moved into the working area of the edging bed (2). Drive mechanisms are provided for the edging bed (2) and the edging jaws (3). The drive mechanisms for the edging lift and the displacement lift are configured as electromechanical drive mechanisms (7) which move the edging bed (2) using driven eccentric cams (12) or cranks. This simplifies the control of the drive mechanisms and reduces the masses of the structural parts being moved.

Abstract: An installation for positioning and welding body parts of different types of motor vehicles. The installation includes a mounting frame (5) which is guided on a conveyor line and which has receiving elements for at least some vehicle body parts. Positioning devices (8) are provided for the vehicle body parts (6) and at least one robot is provided for carrying out welding work. The invention is very flexible in terms of product modifications. The mounting frame (5) has positioning devices for at least some vehicle body parts (6) and clamping devices for the vehicle body parts. An additional (lower) conveyor line (10) is located under the first conveyor (2). One of several auxiliary mounting frames (12) is guided on the additional conveyor line. Parking positions (13) for the auxiliary mounting frames (12) are provided next to the lower conveyor line (10).
