Embodiment Construction

[0020] As shown in 1, 2, 3, and 4 accompanying drawings, the large-opening shape-preserving device used for large-scale aircraft assembly includes an upper-level shape-keeping frame and a lower-level shape-keeping frame.

[0021] The upper layer retaining frame includes the first positioning joint 1, the second positioning joint 2, the third positioning joint 3, the fourth positioning joint 4, the first positioning pin 5, the guide rail 6, the upper layer retaining frame 7, the lifting ring 8, four process Ball head 9, second positioning pin 10.

[0022] The first locating joint 1, the second locating joint 2, the third locating joint 3, and the fourth locating joint 4 are respectively connected with the slide block of the guide rail 6 installed on the upper layer shape-preserving frame 7, and move along the course, and pass through the first positioning pin 5. The second positioning pin 10 is used for positioning, and two suspension rings 8 and four technical ball heads 9 are...

Abstract

The invention discloses a large-opening shape-preserving device used for large-scale airplane assembly. The large-opening shape-preserving device comprises an upper layer shape-preserving rack and a lower layer shape-preserving rack, wherein the upper layer shape-preserving rack comprises a first locator joint, a second locator joint, a third locator joint, a fourth locator joint, and an upper layer shape-preserving frame, and the like. The lower layer shape-preserving rack comprises a lower layer shape-preserving frame, a first frame fixing support, a second frame fixing support, a third frame fixing support, and a fourth frame fixing support, and the like. According to the invention, by utilizing the upper layer shape-preserving rack in coordination with an attitude-adjusting positioner, accurate positioning and installation of a wing body butt joint frame are realized on an airplane body; rigidity of large-opening portions is ensured by the upper and lower layer shape-preserving racks when the airplane body is hoisted and transported; when grand cross butting of an aircraft wing body is carried out, an aircraft body and wings of an aircraft can be butted in place with a stable attitude under the circumstance of non-dismounting the lower layer shape-preserving racks; connection positions of four wing body butt joint frames of the lower layer shape-preserving rack are adjustable in a heading direction and a spanwise direction to ensure design clearance when grand cross butting of the aircraft wing body is carried out.

Description

technical field [0001] The invention relates to a large-opening shape-preserving device used for large-scale aircraft assembly, and belongs to the technical field of aircraft digital assembly. Background technique [0002] The traditional wing and fuselage docking assembly method generally completes the assembly of the middle fuselage and the central wing first, then completes the assembly of the central wing and the left and right outer wings, and then completes the assembly of the front fuselage, rear fuselage and tail section. The docking assembly is the so-called "small cross docking" scheme. However, considering the large size and high manufacturing requirements of large aircraft, after the assembly of the central wing and the fuselage is completed, since the separation surface of the central wing and the outer wing is very close to the fuselage, it can be used when assembling with the left and right outer wings. The assembly space is strictly limited, which makes ...
