Large-span liftable variable-deflection cantilever throwing rod device

Abstract

The invention relates to a large-span liftable variable-deflection cantilever throwing rod device, and belongs to the technical field of rocket engine charging manufacturing robots. The device comprises a mobile end lifting group module, a cantilever rod, a platform base, a fixed end lifting group module, a tail end throwing and coating device and a shell, wherein a guide rail is arranged on the upper surface of the platform base; the movable end lifting group module and the fixed end lifting group module are both arranged on the guide rail and are in sliding fit with the guide rail; the cantilever rod is axially arranged above the guide rail in parallel; the axial head end of the cantilever rod is rotationally connected with the top of the movable end lifting group module; the axial tail end of the cantilever rod is in lap joint with the top of the fixed end lifting group module; the tail end throwing and coating device is sleeved at the axial tail end of the cantilever rod; the shell is of a hollow columnar structure; and the shell is coaxially arranged at the axial tail end of the cantilever rod. The coating device has the capacity of considering the coating quality and efficiency, and can flexibly extend and retract in small spaces of engine shells with different lengths and different diameters, so that the problems in the prior art are solved.

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 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 and high aerodynamic heat. In such a harsh thermal environment, heat 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 prone to static electricity. Sensation, and anti-static measures must also be taken between the engine composite material casing and the internal filler. In order to ensure the successful flight of the missile, China Aerospace 806 Institute has developed a heat-resistant, ant...
