A large-span liftable variable deflection cantilever throwing device

Abstract

The invention relates to a large-span liftable variable-deflection cantilever throwing rod device, which belongs to the technical field of rocket engine charging manufacturing robots; including a mobile end lifting group module, a cantilever rod, a platform base, a fixed end lifting group module, and an end throwing coating device and the shell; the upper surface of the platform base is provided with a guide rail; the mobile end lifting group module and the fixed end lifting group module are both arranged on the guide rail to realize sliding cooperation with the guide rail; the cantilever rod is arranged axially parallel above the guide rail; and the cantilever The axial head end of the rod is rotatably connected to the top of the lifting group module at the moving end; the axial tail end of the cantilever rod is overlapped with the top of the lifting group module at the fixed end; the end coating device is set on the axial tail end of the cantilever rod; the shell It is a hollow columnar structure; the shell is coaxially arranged at the axial tail end of the cantilever rod; while the present invention has both coating quality and efficiency capabilities, it can flexibly expand and contract in a small space with different lengths and different diameters of the engine shell , so as to solve the problems existing in the prior art.

Description

technical field [0001] The invention belongs to the technical field of rocket engine charge manufacturing robots, and relates to a large-span liftable variable deflection cantilever throwing rod device. Background technique [0002] During the flight of the missile in the atmosphere, the working environment is very harsh, and the engine has to withstand the erosion of high heat flux density and high aerodynamic heat. In such a harsh thermal environment, thermal protection must be provided between the engine composite shell and the internal filler; at the same time, during the high-speed flight of the missile in the atmosphere, static electricity will be generated by friction with the air, and the engine propellant is susceptible to static electricity. Therefore, anti-static measures must also be taken between the engine composite casing and the internal filler. In order to ensure the successful flight of the missile, the China Aerospace 806 Institute has developed a paint l...
