Abstract

The invention provides a support device for processing a thin-wall part and a method for processing the thin-wall part. The support device comprises a mounting base, a plurality of buffering devices and a plurality of support parts, wherein the buffering devices are arranged on the mounting base and arrayed along the peripheral direction of the mounting base at intervals; the support parts are respectively connected with the buffering devices; each support part is equipped with a support surface for supporting the thin-wall part; the buffering devices are used for buffering the thin-wall part supported by the support parts. The method for processing the thin-wall part comprises the following steps: mounting the thin-wall part on a flexible multi-point mold and shaping; adopting a flexible clamp for clamping the periphery of the thin-wall part and utilizing an overturning assembly to overturn the thin-wall part from the horizontal position to the vertical position; utilizing a moving assembly to convey the thin-wall part to a processing area of a five-coordinate numerical control milling device; supporting the thin-wall part by the supporting device connected with a swinging head of a five-coordinate numerical control milling system; milling the thin-wall part by the milling device. The support device and method for processing the thin-wall part, provided by the invention, are used for solving the deforming problem of the thin-wall part in the processing process.

Description

technical field [0001] The invention relates to the technical field of processing thin-walled parts, in particular to a support device for processing thin-walled parts used in the milling process of thin-walled parts and a processing method for thin-walled parts. Background technique [0002] Thin-walled structural parts include aircraft skins, automobile covers, etc. The skin is the cover of the aircraft wing and fuselage, and is a key part that constitutes the aerodynamic shape of the aircraft. It has large size, many varieties, complex shapes, and small batches. features. The original processing method mainly adopts the process of mold tooling drawing, edge trimming and multi-step chemical milling. The advanced degree is an important symbol to measure a country's aircraft manufacturing capability and level. [0003] In the traditional production mode of my country's aviation factories, each skin part requires a set of special solid mold tooling for drawing, trimming and ...
