摘要:
The invention relates to a production unit for components, particularly for body components of motor vehicles. In order to be able to time-effectively work on different component types in said production unit within a small space, different component-typical component holders (8, 9, 10) are stored in a tower stack (1), which can be removed from the tower stack (1) by means of a transfer device (3) and can be fed to a workstation (2). Component holders that are no longer required are taken from the workstation (2) and transferred to the tower stack (1) by means of the transfer device (3). During processing in the workstation (2), the transfer device (3) effects the change of the component-typical component holders (8, 9, 10) such that the changeover time is short. The space requirement is small due to the tower stack (1).

The invention relates to a handling system for components having similar shapes, particularly body components for motor vehicles. In said handling system, a gripper (3) located on the arm (2) of a robot (1) can grip one component and the other component that has a similar shape by means of one and the same clamping device (7, 8) without making any adaptations. In order to be able to do so, each clamping device (7, 8) is provided with two split chucks (11a, 11b, 12a, 12b), only one (11a, 11b or 12a, 12b) of which can be controlled in a gripping position while the other one (12a, 12b or 11a, 11b) is located in a neutral position outside the gripping range on the component.

The invention relates to a gripper frame which is used for holding three-dimensional components, in particular, in the motor vehicle industry, and which is fitted with a plurality of support arms (1) for the clamping and/or centering elements (2). The aim of the invention is to avoid having to exchange all of the support arms (1) with clamping and centering elements (2), in the event of a modification of the geometry of the three-dimensional component. As a result, the support arms (1) are fitted with at least one ball joint (29, 30) and/or a longitudinal extension (31) which can pivot, slide and rotate in the clamping and release unit of an adjusting mechanism which is integrated into the support arm (1). The ball of each ball joint (29, 30) and/or the cylinder journal of each longitudinal extension (31) is held in the vicinity of opposing vertexes of the ball or the cylinder journal by shell-shaped clamping jaws (33) with a separation adjustable actuator means, in order to adjust a predefined geometry for one three-dimensional component to the geometry of a different three-dimensional component in a simple manner. Said clamping jaws can be operated by a radially directed pressure force which is produced by a hydraulic force generator (34 to 36) which is arranged in an annular manner about said clamping jaws.

The invention relates to a method for butt welding metal sheets (1, 2), preferably sheet metal strips or blanks of differing thicknesses by the relative displacement of a laser beam or electron beam in relation to the metal sheets (1, 2), along the line of contact of said sheets (1, 2) or the line of the welding seam that is to be produced, with the aid of tension rollers (4, 5, 10) that are located in pairs at a distance from one another above and below the sheets (1, 2) in the vicinity of the welding seam. The tension rollers (10) that are located above the sheets (1, 2) roll off the latter (1, 2) in a height-adjustable and/or sprung manner. The height of the tension rollers (4, 5) that are located below the sheets (1, 2) on at least one side of the welding seam is adjusted.

Die Erfindung betrifft eine multiflexible Fertigungsanlage für aus mehreren Bauteilen zu fügende Zusammenbauten von Kraftfahrzeug-Karosserien. Die Fertigungsanlage weist an mehreren Arbeitsplätzen 3 bis 8 eines Drehtisches 1, 2 auswechselbare Aufnahme- und Spannvorrichtungen 9 bis 14 für Zusammenbauten auf. Den Aufnahme- und Spannvorrichtungen 9 bis 14 ist mindestens ein für Fügeaufgaben eingerichteter Arbeitsroboter 17, 18 zugeordnet, der Fügeaufgaben an den von den Aufnahme- und Spannvorrichtungen 9 bis 14 gehaltenen Zusammenbauten erledigt. Den Drehtischen 1, 2 sind Wechselstationen 19, 20 zugeordnet, mit denen die Aufnahme und Spannvorrichtungen 9 bis 14 auf den Drehtischen 1, 2 gegen andere ausgewechselt werden können. Die Wechselstationen sind vorzugsweise als Drehtische mit verschiedenen Speicherplätzen für die auszuwechselnden Halte- und Spannvorrichtungen 29 bis 34 ausgebildet. Die für die Bearbeitung verschiedener Typen von Zusammenbauten benötigten verschiedene Halte- und Spannvorrichtungen sowie Greifer für Laderoboter werden genauso wie die zu bearbeitenden Bauteile ausschließlich von außen zugeführt, wenn eine Umstellung von einem Typ auf einen anderen Typ von Zusammenbauten gewünscht wird.
摘要:
The invention relates to a method for laser-cutting (s) structural components (1, 2) to be joined, wherein the laser radiation is guided by means of a computer-controlled handling system in which an ideal trajectory (SB) is defined for every structural component (1, 2). Said desired track corresponds to a joining line that is bent due to an especially three-dimensional structural component (1). The method is further characterized in that the surfaces (TO1, TO2) of the structural components (1, 2) that comprise the joining line are measured. On the basis of the results of measurement thereby obtained an ideal trajectory (SB) that corresponds to a penetration line (D) of the structural components (1, 2) is calculated. On a structural component surface (TO1, TO2) resulting from said measurement a mark (Ma) is attached on said structural component surface (TO1). The joint of the cut produced by cutting a structural component (1) and the mark (Ma) of the structural component surface (TO1) are measured and, if the joint of cut (3) deviates from the ideal trajectory (SB), the handling system is controlled during cutting in order to eliminate said deviation.

The invention relates to a method for cleaning folding rolls (2, 3) arranged on a robot arm and guided along a folding flange during the folding process. According to said method, the folding rolls (2, 3) fixed to the robot arm are rotated in a cleaning station (1) by means of a drive device (4), and the running surfaces (11) of the folding rolls (2, 3) are cleaned. The folding rolls (2, 3) are driven by means of a friction wheel (6) engaging from the outside.
