Pneumatic inner support device for thin-walled cabin

Abstract

A pneumatic internal support device for a thin-walled cabin, including a positioning seat, four pneumatic claws, a support plate, and a manual switch valve, the pneumatic internal support device is positioned on the foundation plane through the positioning seat, and the manual switch The control of the compressed air by the valve makes the struts of the pneumatic four-jaw retractably stretch out to support the thin-walled cabin body. According to the pneumatic inner support device of the thin-walled cabin body of the present invention, when milling the thin-walled cabin body, the cutting force is relatively large during milling, and the thin-walled cabin body is caused by poor system rigidity, vibration and elastic deformation. It is difficult to guarantee the processing accuracy of blind slots and mouth frames, which solves the problem of unsupported milling tooling in the cabin cavity that was commonly used in the past.

Description

technical field [0001] The invention relates to the processing of a thin-walled cabin body, especially a titanium alloy cabin body with a complex inner cavity structure. Background technique [0002] Cabin processing is particularly important in tactical missiles. As we all know, the structural parts of the missile are composed of multiple cabins plus a body, wing surface, rudder surface, and seeker. With the increase of the range, the speed of the missile is getting higher and higher, and the wall thickness of the cabin is required to be thinner and thinner. More and more heat-resistant, high-strength and lightweight materials are used. Titanium alloy materials have been widely used in the cabin of air-to-air missiles. There are more and more holes, slots, notches, and mouth frames required to be processed on the cabin body. When processing the above-mentioned mouth frames and holes, the cabin body needs to be positioned and fixed on the machine tool table. In the past, th...
