Solid rocket engine end socket section inner heat insulation layer pasting device

Abstract

The invention discloses a solid rocket engine end socket section inner heat insulation layer pasting device. The device comprises a rotating device and pasting devices, an engine shell is placed on an adjusting platform, the two pasting devices are arranged on the rotating device to conduct heat insulation layer pasting on a rear end socket section and a front end socket section of the engine shell respectively, the two pasting devices enter into working positions in sequence through the rotating device, heat insulation layers are attached to a pasting arm, a pasting angle is controlled through a joint module, the pasting devices can enter into the interior of the engine shell conveniently, pressure is applied to the pasting arm through a lead screw sliding block mechanism, the manual pasting process is simulated, meanwhile, the rotating mechanism rotates according to a set angle, so that the pasting arm rolls and presses all areas of the heat insulation layers, 360-degree rolling and pressing of the heat insulation layers are achieved, the pasting quality of the heat insulation layers is guaranteed, the high-complexity operation problems of manual rolling and entering into the shell by technical workers are solved, the pasting efficiency is improved, and the operation difficulty is reduced.

Description

technical field [0001] The invention relates to the technical field of rocket motor manufacturing, in particular to a device for adhering a thermal insulation layer in a head section of a solid rocket motor. Background technique [0002] The inner heat insulation layer of the solid rocket motor shell includes three parts: the straight line section of the cylinder body, the front head section and the rear head section. The inner heat insulation layer of the solid rocket motor is a thermal protection material located between the inner surface of the shell and the propellant. It can take away most of the heat through its own continuous decomposition and ablation to slow down the propagation speed of the high temperature of the gas to the shell and avoid The engine casing reaches a temperature that endangers its structural integrity in a high-temperature, high-pressure gas environment to ensure the normal operation of the engine. [0003] At present, the head of the metal casin...

Problems solved by technology

Manual debonding molding inevitably has difficult operations, poor paving quality, and low process efficiency, resulting in a lot of gas and bubbles between layers, and then the quality problem of debonding is prone to occur after the thermal insulation layer is cured, resulting in the rocket working process. , the thermal insulation layer formed by artificial debonding is likely to cause serious problems such as the decline of thermal protection ability, excessive local temperature and even thermal deformation.

[0004] The existing technology for forming the thermal insulation layer in the head section of the solid rocket motor shell still relies on traditional manual debonding molding, or even if the molding process is optimized, it is still inseparable from manual operation, and it is impossible to achieve the inner thermal insulation layer in the molding process.
