Embodiment Construction

[0028] This embodiment is a multi-point flexible positioning tool for positioning and supporting the upper left wall of a certain type of wing.

[0029] as attached figure 1 As shown, this embodiment includes a plurality of Cartesian flexible support modules 1 and bases 2 . A plurality of Cartesian coordinate flexible support modules 1 are arranged and fixed on the upper surface of the base 2 . There is a gap of 5-10 mm between the Cartesian coordinate flexible support modules 1 , and in this embodiment, the gap between the Cartesian coordinate flexible support modules 1 is 10 mm.

[0030] The base 2 is square, and its surface size is determined according to the size of the largest projected surface of the part to be clamped, and the surface size of the base 2 is larger than the maximum projected size of the part to be clamped.

[0031] as attached figure 2 As shown, the rectangular coordinate type flexible support module 1 includes an x-direction sliding unit 6 , a y-direct...

Abstract

The invention discloses a multi-point flexible positioning tool which comprises a plurality of rectangular coordinate type flexible support die blocks and a base, wherein the plurality of rectangular coordinate type flexible support die blocks are arranged and fixed on the upper surface of the base; an X-direction sliding panel in each rectangular coordinate type flexible support die block is driven by a driving mechanism to do straight reciprocating motion along an X-direction straight guide track; and a Y-direction sliding panel in each rectangular coordinate type flexible support die block is driven by the driving mechanism to do straight reciprocating motion along a Y-direction straight guide track. The multi-point flexible positioning tool can ensure precise positioning of a thin-walled curved part, rapidly form an optimal support array which is matched with the surface of the part according to three-dimensional information and machining information of the thin-walled curved part to be clamped under the control of a computer control unit, and alleviate the deformation of a workpiece which is stressed and heated in a machining state, thus improving the manufacturing quality and the manufacturing efficiency of the part; and moreover, the tool can also be taken as an assembling tool to assemble the thin-walled curved part, and can effectively improve the machining efficiency and the machining quality of the part.

Description

technical field [0001] The invention relates to the field of aircraft manufacturing, in particular to a multi-point flexible positioning tool for panel processing. Background technique [0002] There are many thin-walled curved surface parts with relatively large geometric dimensions on the aircraft, such as wall panels, which are difficult to accurately position and clamp during the manufacturing and assembly process. The traditional rigid tooling is based on the curved surface of the part to manufacture a solid mold tire or a positioning clamp with the same curved surface to locate and clamp such parts. This type of tooling has poor interchangeability and must be aimed at different parts. Manufacture different special tooling, the design, manufacture, transportation, storage and management of this kind of tooling need to consume huge manpower and material resources and is not conducive to the development of new products and single-piece small batch production, this traditio...
