Aircraft pod milling tooling and machining manufacturing method

Abstract

A milling tool for an aircraft air pod, the milling tool includes a milling positioning tool inside a shell and a milling positioning tool outside the shell, which realizes the positioning and clamping of the internal and external milling of the castings of the aircraft air pod, which avoids over-positioning and makes the special-shaped thin-walled The window part is reliably supported and positioned to ensure the flatness of the special-shaped thin-walled window part, so that the sapphire glass is reliably sealed. The invention also discloses a machining and manufacturing method of an aircraft air pod, by adjusting the pressure contact of the screw to the aircraft air pod casting, the support strength and rigidity of the aircraft air pod casting are enhanced, and the impact of the milling force on the aircraft air pod is reduced. The amount of deformation produced by the casting of the pod. The invention abandons the traditional positioning method, adopts the adjustable support positioning for the air pod of the aircraft, combines the process through hole, and can accurately grasp the same processing coordinate when milling inside and outside the shell, reducing the processing inside and outside the shell The overturn error at the time can ensure the internal and external dimension requirements of the air pod of the aircraft.

Description

technical field [0001] The invention relates to the technical field of machining, in particular to an aircraft air pod milling tool and a machining manufacturing method. Background technique [0002] The air pod of the aircraft is installed outside the aircraft, and various sensors are installed inside it, and various sensors detect external information through the sapphire glass window on the pod. like figure 1 As shown, the air pod of an aircraft has a complex shape, including a mounting part, a side window part and a roof window part. Among them, the installation part is connected to the aircraft body, and sapphire glass is installed on the side window part and the roof window part. [0003] In terms of materials, the aircraft air pod is required to be light in weight and have sufficient strength. Therefore, the manufacture of aircraft air pods uses titanium alloy castings, which are realized by milling. Titanium alloy has high specific strength and high thermal stren...

AI Technical Summary

Problems solved by technology

Since the air pod of the aircraft is a large-area hollow shell, deformation and out-of-tolerance are prone to occur at the special-shaped thin-walled window during processing, resulting in scrapping

[0006] Only a five-axis machining center can process this complex shape of the aircraft air pod, but due to the above reasons, the usual machining manufacturing methods are difficult to achieve processing, so the processing pass rate of the aircraft air pod is very low
