Patent number: 7854361Abstract: The assembly of body components using a geometry box (1) and clamping frames (7, 8) is described. At least for the larger components (9, 10), in particular the side wall parts of the body, a multipart clamping frame (8a, 8b) is used. The component (9, 10) is grasped and fed to the geometry box (1) using one clamping frame part, while the other clamping frame part is fed empty. Using both clamping frame parts, the component (9, 10) is then fixed precisely in position using positioning and fixing units acting between the geometry box (1) and the clamping frame (7, 8) in such a way that the components (6, 9, 10) to be connected to one another may be connected to one another, in particular welded.Type: GrantFiled: April 24, 2006Date of Patent: December 21, 2010Assignee: ThyssenKrupp Drauz Nothelfer GmbHInventor: Gerd Gauggel

Patent number: 7837084Abstract: Adjustable, elongate, beam-offset jig structure for assisting in welding a pair of beam-end, column-interface components to the opposite ends of an elongate beam. The jig structure includes spaced, adjustable head-stock and tail-stock structures, each capable of holding such a component adjacent a beam end for adjustment to an infinite number of different, pre-weld angular-offset dispositions relative to such a beam end in order to accommodate planned horizontal and vertical beam offsets which will be encountered when such beams are installed in a building frame. A computer-controlled, robotic welder is preferably provided adjacent each end of the jig structure to implement appropriate welding when any and all offset angles have been jig-established.Type: GrantFiled: May 30, 2008Date of Patent: November 23, 2010Assignee: ConXtech, Inc.Inventor: Robert J.

Patent number: 7828194Abstract: Plate members 17 are respectively rested on first and second tables IA and IB relatively movable toward and away from each other. The plate members 17 are caused to abut against reference positioning members 16a and 16b of reference positioning devices protruded ahead of and over opposing ends 1? of the tables IA and IB so that opposing ends of the plate members 17 are positioned in protrusion ahead of the opposing ends 1? of the tables IA and IB, and the plate members 17 are positioned laterally. Then, the positioned plate members 17 are locked on the tables IA and IB. After the reference positioning devices are retracted, the tables IA and IB are relatively moved toward each other to cause the opposing ends of the plate members 17 to abut together for formation of weld line X.Type: GrantFiled: March 4, 2010Date of Patent: November 9, 2010Assignee: IHI CorporationInventors: Kenji Iimura, Tomoo Mizuno, Katsura Oowaki, Hirotaka Kanazawa, Chikamasa Iwamoto, Toshikazu Yagi, Hirotaka Shirai
