Embodiment Construction

[0018] Such as figure 1 , figure 2 As shown, the basic platform 1, the first three-coordinate locator 2, the second three-coordinate locator 3, and the third three-coordinate locator 5; among them, the three three-coordinate locators are installed on the basic platform 1, through Certain configuration and parameter setting are to adapt to the fuselages of different shapes and sizes; The implementation steps of the present invention are:

[0019] a) Select the supporting main frame on the simulated fuselage sample 4 and install the technical ball head;

[0020] b) According to the position of the process ball head on the simulated fuselage sample 4, a three-coordinate positioner is configured, and its Z-direction stroke is set at the lowermost section;

[0021] (c) hoisting the simulated fuselage sample 4 above the three-coordinate locator, within the stroke range of the three three-coordinate locators;

[0022] d) Measure and calculate the relative position of the process ...

Abstract

The invention relates to a method for positioning airframes by three-point floating. Devices which need to be used in the method comprise a base platform 1, a fist 3-axis localizer, a second 3-axis localizer and a third 3-axis localizer, wherein the three localizers are installed on the base platform, and are provided with certain configuration and parameter setting so as to adapt to the airframes with different shapes and sizes. The method has the advantages of: (1) repeated point-moving feeding for searching accurate supporting positions; (2) stable and reliable positioning; (3) high efficiency of positioning operation; and (4) capability of realizing the true unstressing positioning.

Description

technical field [0001] The invention relates to a three-point floating-in-position method of a fuselage during aircraft assembly. Background technique [0002] In the field of aviation manufacturing, the problem of docking assembly of large parts cannot be avoided. In order to realize the docking assembly of parts, it is necessary to adjust the pose of large rigid body parts such as aircraft fuselage. Aircraft fuselage parts are a unique operating object. It is not allowed to adjust the tooling to cause damage to the fuselage surface or internal components. . In the traditional assembly process based on a fixed frame, large parts are positioned and clamped by the frame. Due to the existence of manufacturing and assembly errors between the tooling and the fuselage, a certain amount of internal force will cause the fuselage to deform, which will affect the connection after the docking is completed. aerodynamic shape of the aircraft. In the aircraft digital assembly process,...
