  • Patent number: 11273896
    Abstract: To simplify the structure of a holding fixture which holds the shape of the aircraft panel and conveys the aircraft panel, an object is to ensure shape accuracy required in the manufacturing process and hold an aircraft panel in an appropriate shape, in combination with a holding fixture. A shape holding fixture includes: a plurality of support units configured to be positioned on a lower surface side of an aircraft panel, and provided at intervals along a one-axis direction, the aircraft panel being held by a holding fixture configured to grip an edge portion of the aircraft panel; and a shape holding unit provided to each of the plurality of support units, including a rod which supports the aircraft panel from the lower surface side of the aircraft panel, and configured to adjust a position where the rod comes into contact with the aircraft panel to support the aircraft panel, corresponding to the shape of the aircraft panel.

  • Patent number: 10843820
    Abstract: An object is to simplify a structure of a holding fixture which holds the shape of an aircraft panel, and to hold the aircraft panel in an appropriate shape. A holding fixture includes: a plurality of gripping units configured to grip edge portions on two opposite sides of a fuselage panel including a skin; and a support body configured to integrally support the plurality of gripping units, the support body being provided corresponding to the fuselage panel to be gripped by the plurality of gripping units, wherein the plurality of gripping units hold the fuselage panel such that the gripping units grip the edge portions of the fuselage panel, and the fuselage panel has a curved shape in cross section taken in a direction perpendicular to a one axis direction, and the holding fixture is configured to be conveyable in a state of holding the fuselage panel.

  • Patent number: 9597781
    Abstract: An assembly jig includes an upper jig frame that is provided above a longitudinal outer edge of a large structure, a lower jig frame that is provided below a longitudinal outer edge of the large structure, a connecting jig frame that connects the upper jig frame and the lower jig frame to each other, three supporting parts for supporting the lower jig frame from below, and a jig leg portion that is provided perpendicular to the direction in which the lower jig frame extends and parallel to a ground surface. The supporting parts are provided at three portions that are respectively located under two end portions of the jig leg portion and under the lower jig frame, and arrangement positions of the supporting parts provided at the three portions form a substantially triangular shape when seen from above.
