Patent number: 7163247Abstract: Device at tool holder (10) of the kind comprising an essentially C-shaped frame preferably having a long inner range, which frame at its free shank ends carries said tool, for instance a riveting, a glueing or a welding unit. The holder (10) comprises a truss or frame work, which includes an outer and an inner C-shaped frame (11, 23) and a number of slewing brackets (27–32) connected to these. The frames (11, 23) and the slewing brackets (27–32) are arranged to form a number of connected triangular sections, which connection points (18–22, 37) are designed as intersections or joints. The outer C-shaped frame (11) is arranged only to support thrust forces and the inner frame (23) thrust and tensile forces and the slewing brackets (27–32) substantially tensile forces.Type: GrantFiled: October 21, 2002Date of Patent: January 16, 2007Assignee: C-Power Technologies ABInventors: Karl-Otto Stromberg, Hans Hellman, Dan Holm, Peter Froberg

Patent number: 6609851Abstract: Disclosed is a coupling device having two coupling parts and clamping means for releasably axially clamping both coupling parts. A plurality of circumferentially spaced non parallel grooves are cut into the surface of one of both coupling parts for having a reference in a plane perpendicular to the clamping direction. Pins project from the surface of the other coupling part each pin having two opposing parallel lateral surfaces for obtaining alignment of the grooves with the pins upon clamping. At least one of the lateral surfaces of each pin forms an angle with the associated flank of each groove upon axial alignment of the coupling parts. For improving the repeated precision of the positioning of one of the coupling parts relative to the other coupling part even upon high stress on one of the coupling parts in circumferential direction a clamping plate is provided between the lateral surface and the associated flank which is axially elastic and is mounted to one of the coupling parts.Type: GrantFiled: December 16, 1999Date of Patent: August 26, 2003Assignee: System 3R International ABInventors: Hakon Nordquist, Dan Holm, Hans Hellman, Peter Fröberg

Patent number: 6467826Abstract: An essentially C-shaped tool holder (10), preferably having a long inner edge, which holder at its free shank ends can carry a tool such as a riveting, glueing or welding unit. The holder (10) comprises a truss or frame work which includes an outer and an inner C-shaped frame (11, 23) and a plurality of slewing brackets (27-32) connected to the C-shaped frames. The frames (11, 23) and the slewing brackets (27-32) are arranged to form a number of connected triangular sections, defined by connection points 18-22, 37) which are designed as intersections or joints. The outer C-shaped frame (11) is arranged to support only thrust forces; the inner frame (23) is arranged to support thrust and tensile forces, and the slewing brackets (27-32) are arranged substantially to support tensile forces.Type: GrantFiled: December 8, 2000Date of Patent: October 22, 2002Assignee: C-Power ABInventors: Karl-Otto Strömberg, Hans Hellman, Dan Holm, Peter Fröberg
