A processing method of thin-walled membrane disc based on soft tire lamination and clamping

Abstract

The invention discloses a thin-wall film disc machining method based on soft base fitted clamping. The method is a novel machining method which applies the soft base clamp fitting technology to turning of thin-wall film disc parts. According to the method, a surface appearance measuring device is adopted to measure the appearance of a machined surface, a precise machining device is adopted to machine a corresponding soft base clamp to be attached to the machined surface, machining errors caused by large stress deformation of a thin-wall part in traditional machining are avoided, machining precision is improved greatly, machining efficiency is improved to a great extent, the thinnest part of a machined thin-wall film disc part can reach 0.3 mm, the dimensional precision is smaller than a standard of + / - 0.008. Aerial thin-wall film discs machined through the method can meet using requirements of aero-engines.

Description

technical field [0001] The invention relates to a processing method, in particular to a thin-walled membrane disk processing method based on soft tire bonding and clamping. Background technique [0002] With the development of science and technology and industrial production, higher requirements are put forward for the machining accuracy and surface quality of mechanical parts. High output, high quality, low consumption, good product technology and long service life are the basic goals pursued by the machinery manufacturing industry, and the basis for the realization of these goals is machining accuracy. And precision thin-walled parts (usually refers to parts with wall thickness <1mm) can reduce the number of parts and the workload of assembly. A thin-walled integral part can replace the original parts composed of dozens or even hundreds of parts, and the assembly takes up The working hours are reduced by more than 30%, and the service life is increased at the same time...

AI Technical Summary

Problems solved by technology

For the thin-walled disc parts that have been processed and deformed during the rough machining process, the rigid clamping fixture, such as figure 2 As shown, clamping stress deformation will occur on thin-walled disc parts, such as figure 2 shown in I; after processing, clamping stress deformation will lead to stress recovery deformation after clamping, such as figure 2 As shown in II, which affects the final machining accuracy of thin-walled disc parts
