Abstract

The invention relates to the technical field of machining clamping devices, in particular to a clamping device and method for surface machining of a high-gradient conformal bow cap. The clamping device and method for surface machining of the high-gradient conformal bow cap aim to solve the problems of difficult precision safety clamping and difficult detachment after conventional machining during outer surface machining of the high-gradient conformal bow cap at present. The clamping device comprises a clamp base, a positioning component and a fixing mechanism, wherein the positioning component is fixedly connected to the upper end surface of the clamp base; a plurality of curved lug bosses are uniformly distributed on the outer side wall of the positioning component in the axial direction; each curved lug boss is arranged in the outer circumferential direction; a curvilinear equation formed by the outer surfaces of the curved lug bosses is the same as that of the inner surface of the bow cap; and the positioning component comprises a plurality of clamp base bodies which are uniformly distributed in the circumferential direction to form the conical positioning component and are fixedly connected through the fixing mechanism. The clamping method comprises the following steps of painting of low-stress glue; bonding molding; dismounting of the clamping device; and removal of the bow cap. The clamping device and the clamping method are used for surface machining of the bow cap.

Description

technical field [0001] The invention relates to a clamping device and a clamping method for surface processing of a high-steep conformal hood. Background technique [0002] In order to adapt to the development of high-speed aircraft and balance the aerodynamic requirements of the aircraft, the contradiction between stealth and optical performance, conformal optical components came into being, that is, to smoothly adapt to the external shape of the system platform for the purpose of improving the aerodynamic performance of the system optical window. The primary key element in the application of conformal optical components is the aircraft's hood. Compared with the traditional hemispherical hood, the high-steep conformal hood can significantly reduce the flight resistance of the aircraft, improve the air flow field around the aircraft, and reduce the Effects of small aero-optical effects on image quality inside aircraft. [0003] Compared with the traditional hemispherical h...
