Problems solved by technology

When the design of the supporting tool is too large, it is difficult to transfer the heat insulation sleeve and there is a risk of deformation of the heat insulation sleeve
At the same time, mechanical grinding also has the following problems: (1) The workload of grinding is relatively large
Both the inner and outer surfaces of the insulation sleeve need to be treated, and the flipping and grinding of the insulation sleeve takes a long time
(2) Grinding produces a large amount of dust, which seriously endangers the health of the operator

Abstract

The invention provides a heat insulation sleeve grinding surface treatment device and method. The device comprises a numerical control machine tool and a grinding machine; a fixed membrane is clamped on a machine tool chuck of the numerical control machine tool; an air hole is formed in the head of the fixed membrane; an air pipe is arranged at the tail of the fixed membrane, and the air pipe is communicated with compressed air through a first branch pipe; and the air pipe is connected with a first vacuum pump through a second branch pipe, and valves are arranged on the first branch pipe and the second branch pipe. The device and the method of the invention facilitate grinding and fixing of a heat insulation sleeve and can remove an inert layer on the surface of the heat insulation sleeve.

Description

technical field [0001] The invention belongs to the field of solid rocket motor production and manufacturing, and in particular relates to a grinding surface treatment device and method for adiabatic sleeves. Background technique [0002] The thermal insulation sleeve is an indispensable support for the heat-proof structure of the advanced solid rocket motor, and is one of the important factors affecting many performances of the solid rocket motor, such as the filling ratio, impulse-to-mass ratio, structure, safety and reliability. The insulation sleeve material is a non-metallic heat-insulating and ablation-resistant elastic material. Its main function is to insulate and protect the shell of the solid rocket motor combustion chamber, preventing high-temperature and high-pressure gas from reducing the strength of the shell and endangering its structural integrity. , in the solid rocket motor with the charge block structure, the heat insulation sleeve also has the function of...
