  • Patent number: 8402806
    Abstract: Installation/processing tools may be used to install one or more expandable structures in a workpiece. An installation/processing tool may include an expansion mandrel, a processing tool, and an expansion assembly having an expansion jaw movable between a collapsed configuration and an expanded configuration. An expandable portion of the expansion jaw is sized to fit within a passageway of an expandable member. When the mandrel is moved through the expansion assembly, the expansion jaw is moved between the collapsed and expanded configurations to cause expansion of the expandable member. The installation/processing tool can also be used to cold work a workpiece.

  • Patent number: 8387436
    Abstract: An alignment device is located on a mandrel of an installation tool and is used to align a structural member in an opening of a workpiece while seating a radial flange of the structural member against a first surface of the workpiece. The alignment device comprises a disk-shaped device having an outer surface, an inner surface forming an opening through the alignment device, and where the opening is sized to be at least slightly smaller than a major diameter of an expansion portion of the mandrel. In one embodiment, the alignment is nylon to allow the inner surface of the alignment device to be repeatedly, radially expanded and yet the opening formed by the inner surface returns to its original size.

  • Patent number: 8117885
    Abstract: Self-aligning tools may be used to install and reposition an expandable structure in a workpiece. A self-aligning installation system may include an expansion mandrel, self-aligning nose cap assembly, and an installation tool for driving the mandrel. The expansion mandrel is sized to fit within a passageway of an expandable member such that the expandable member radially expands when the expansion mandrel is moved through the passageway. The self-aligning nose cap assembly moves relative to the installation tool and mandrel. A self-aligning seating system can be used to move the installed expandable member. The self-aligning seating system includes a seat backing, a seat base, and a pull rod coupled to the seat backing and extending through the seat base. The seat backing slidably engages the seat base to permit rotation of the pull rod.
