Embodiment 1

[0018] follow the next figure 2 Clamp the part blank in the same way, after the first surface is completely finished, on the processed surface (see figure 1 ) to cover the effective area of ​​the part (exposed area on the surface of the part, except the blank surface) as much as possible to prevent corrosion after pouring plaster. Then pour gypsum into it, and after the gypsum is completely hardened, perform super-flat treatment on the side where the gypsum is laid (injecting gypsum makes the processed curved surface no longer suspended, completely eliminating the out-of-tolerance of parts caused by vibration). After super-flatness is required, the plaster surface is consistent with the rough surface. Then turn the part upside down and fasten it on the fixture, and tighten it with bolts. Roughing and finishing are performed on the other side. This kind of operation can completely avoid the out-of-tolerance caused by the vibration of the part due to hollowness after one sid...

Abstract

The invention belongs to a numerical control processing technology of an airplane, and provides a machining method of a thin-wall curved surface type part. The machining method comprises the following steps: laying a soft leather cushion on a curved surface of a machined part; filling gypsum into the region on one side of the machined part on which the leather cushion is laid; after uniformly hardening the gypsum, performing super-flat machining on the region, in which the gypsum is filled, on a numerical control machine tool to guarantee that the super-flat region of the gypsum is flush with the bottom surface of a tool.

Description

technical field [0001] The invention belongs to aircraft numerical control processing technology, and relates to a processing method of thin-walled curved surface parts. Background technique [0002] Nowadays, the processing of many thin-walled and large curved surface parts will lead to poor processing quality, deformation, out-of-tolerance, or even scrapping of parts due to parts vibration during processing. The vibration of parts during processing is sometimes unavoidable, how to minimize the vibration during processing is an urgent problem to be solved. Contents of the invention [0003] The purpose of the present invention is to provide a processing method for thin-wall curved surface parts, and improve the processing quality of thin-wall large curved surface parts. [0004] The technical solution of the present invention: a method for processing thin-walled curved surface parts, comprising: [0005] Lay a soft leather pad on the curved surface of the finished part;...
