Machine body positioning and posture adjusting device and method

Abstract

The invention provides a machine body positioning and posture adjusting device, comprising a first positioning device, a second positioning device and a central control device, wherein the first positioning device and the second positioning device are provided with flexible supporting boards for supporting a machine body in an adjusting process; and the central control device is driven in a posture adjusting process and guides the first positioning device and the second positioning device to move. The invention further provides a machine body positioning and posture adjusting method. With the adoption of the machine body positioning and posture adjusting device and method provided by the invention, the structural deformation can be reduced; and the space position posture of the machine body is automatically adjusted for six freedom degrees.

Description

technical field [0001] The invention relates to the field of aircraft assembly. Specifically, the present invention relates to a positioning system for a fuselage barrel section, and relates to a method and process for adjusting the position and attitude of the fuselage barrel section during the docking process. Background technique [0002] The docking assembly of large aircraft components refers to the docking of the fuselage barrel section and the outer wing / fuselage (including the central wing). The quality directly affects the aerodynamics and flight safety of the aircraft. Since the 1990s, the production lines of Airbus and Boeing have generally adopted flexible docking systems based on automatic measurement and positioning. AIT of the United States, M.Torres of Spain, and Baojie Company of Germany have all developed their own products and become mainstream suppliers in the industry. The use of flexible docking equipment greatly speeds up the docking progress and imp...

Problems solved by technology

In addition, the support methods are joint-type, resulting in force concentration near the support joints, resulting in greater stress concentration and resulting deformation

The above method has the following disadvantages: 1. The system structure is complex; 2. The increase in the number of motors, the increase in the performance requirements of the control system, and the increase in the measurement and synchronization of the movement of each axis will undoubtedly increase the system cost; 3. Low reliability, free control The higher the degree, the more the process of motion decoupling is required, which not only increases the complexity of the leveling algorithm, but also increases the problem of destroying the system due to over-constraint caused by algorithm instability or hardware failure; 4. For manufacturing and installation , measurement and foundation requirements are high

[0003] At present, the docking of large parts of domestic aircraft still follows the traditional assembly process in a large number, using a large number of tooling positioning, long cycle, labor-intensive workers, low and unstable assembly quality
