Abstract

The invention relates to a manufacturing method for an aircraft steering engine body. The manufacturing method comprises the steps that firstly, a gas pipeline of a casting for manufacturing the aircraft steering engine body is filled with pasty wax, and cooling is conducted; and secondly, rough machining treatment, fine machining treatment and dewaxing treatment are sequentially conducted on thecasting filled with the wax, and the aircraft steering engine body is obtained. According to the manufacturing method for the aircraft steering engine body, the technological method of sequentially conducting plugging, machining and dredging is innovatively proposed, the gas pipeline is filled with the wax before machining is conducted, therefore, gas outlet pipeline cutting contamination can be effectively prevented, the product quality is guaranteed, and the machining cost is greatly reduced.

Description

technical field [0001] The invention relates to a method for manufacturing an aircraft steering gear body, which belongs to the field of mechanical processing. Background technique [0002] The body of the aircraft steering gear is made of high-strength aluminum alloy precision casting. During the processing, the air outlet pipe is easily polluted by cuttings. The pollutants stick to the inner wall of the stainless pipe, making cleaning very difficult, which seriously affects the normal production of the steering gear body. The original cleaning process is to use high-pressure air gun or high-pressure water gun to wash after each processing procedure, and then clean with cleaning liquid. The cleaning effect is very unsatisfactory, and the cuttings are often blocked and the product is scrapped. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the invention provides a method for manufacturing the steering gear body of an aircraft to solve the p...
