Problems solved by technology

The traditional aircraft assembly method uses a large number of assembly jigs to clamp, position and support the various parts of the aircraft, and then carries out docking assembly through manual assistance. The degree of automation is low, resulting in low production efficiency and unstable quality.
Moreover, different types of aircraft need to be customized with special tooling, with many types and quantities, long manufacturing cycle, high cost and low efficiency
It can be seen that there is still a big gap between domestic and foreign countries in the application of flexible assembly technology and frameless assembly technology.

Embodiment Construction

[0056] like figure 1 As shown, the cylinder 16 is fixed on the y-direction slider 15 , and the z-direction moving cylinder 17 can move up and down in the cylinder 16 in the axial direction. The end effector 18 is a spherical hinge structure, which is connected with the wing components by vacuum adsorption. During attitude adjustment, the x- and y-direction moving sliders and the z-direction moving cylinder are driven by servo motors, and the position and posture of wing components required for attitude adjustment can be measured by a laser tracking measurement system.

[0057] like figure 2 As shown, the ball seat is fixed on the top of the z-direction moving cylinder through a threaded connection, and the ball head is fastened by a tension spring 12 and a pin 13 . The ball head 5 can rotate around the center of the ball in the ball seat 11, on which a vacuum suction cup and a nylon washer are installed. When adjusting the attitude, the vacuum generator draws a vacuum from...

Abstract

The invention discloses a three 3-axis localizer-based method for safely (stably) adjusting the pose of airfoil member. The mode for flexibly adjusting the pose of the airfoil member, which is based on 3-axis vac-sorb localizers, is adopted; by analyzing the dynamical property of an actuator on the vac-sorb terminal of each localizer and establishing the pose adjusting dynamic model of the airfoil member, the evaluation index of the firm holding stability of the pose adjustment is defined; and according to the evaluation index, factors which influence the firm holding stability are analyzed, and the following measures are adopted to ensure the firm holding stability during pose adjustment: when the airfoil member needs to be laid on a supporting point, a much more horizontal position needs to be selected; the pose accuracy of positioning needs to be increased as much as possible during hoisting positioning, and the rotational angle of the spherical head of the terminal actuator is reduced; and under the premise that the efficiency of pose adjustment is ensured, the speed and the accelerated speed of the pose adjustment are reduced as as much as possible.

Description

technical field [0001] The invention relates to a method for adjusting attitude by using a three-coordinate locator to support wing components. Background technique [0002] In the modern aircraft assembly production process, due to the large size of each assembly component, complex structure, and a large number of parts and connectors, the aircraft assembly task has become a comprehensive system engineering with a long cycle, high technical difficulty, and many disciplines. At the same time, it largely determines the final quality and cost of the aircraft. Developed countries attach great importance to the research and development of aircraft assembly technology. The European Union clearly stated in 1994 that it is necessary to study the flexible assembly system of aviation products based on collaborative multi-functional operating robots. The long-term goal is to develop frameless airframe assembly technology. . Airbus, Boeing and other companies take this technology as ...
