Abstract

The invention relates to a flexible structure machining and finishing auxiliary supporting device and an adjustment method, and discloses an auxiliary supporting device and an adjustment method which are applied in the machining and finishing process of a cantilever flexible structure in the field of spaceflight. The flexible structure machining and finishing auxiliary supporting device comprises an upright column, transverse fixed rods, rubber gaskets, rotating rods, supporting rods, nuts and oblique fixed rods; the transverse fixed rods are located on the top surface of the upright column, are connected with the upright column and are used for mounting the supporting rods; the oblique fixed rods are connected with the upright column and the transverse fixed rods; the rotating rods penetrate through the supporting rods transversely, are welded firmly and are used for rotating the supporting rods to adjust the heights of the supporting rods; and the rubber gaskets are pasted at the tops of the supporting rods through glue and are used for protecting supporting surfaces and reducing impact force in the machining process. Flutter in the machining and finishing process of the cantilever flexible structure can be eliminated to the greatest extent, and the machining precision of a spacecraft payload mounting surface can be improved.

Description

technical field [0001] The invention relates to an auxiliary support device and adjustment method for processing and trimming of flexible structures, in particular to an auxiliary support device and adjustment method for the processing and trimming of cantilever flexible structures, which are applied in the field of aerospace. Background technique [0002] With the wide application of satellite payload technology, technologies such as high-precision earth observation, astronomical observation, and high-precision spacecraft control have put forward higher precision requirements for satellite payloads and stand-alone aircraft. The payload with high pointing precision also puts forward higher and higher precision requirements for the installation structure. [0003] For the payload mounting surface on the cantilever flexible structure, the chatter problem of machining has always been a difficulty in high-precision combined machining technology. Due to the weak local rigidity o...
