Embodiment 1

[0043] This embodiment provides a method for grinding heat insulating materials.

[0044] The workpiece to be polished is a metal cylindrical workpiece that is enclosed within the engine combustion chamber of the aircraft engine. The length of the metal cylindrical workpiece is 2m, and its diameter is 500mm. The metal to be polished is polished by the workpiece 7 to be polished. A thermal insulation material 71 is laid on the inner surface of the cylindrical workpiece, and the thermal insulation material is made of ceramic material. The inner surface of the metal cylindrical workpiece (that is, the heat insulation material) of the heat insulation material laid on the inner surface is generally ground.

[0045] The workpiece described in this embodiment is placed on the support frame formed by the driving support wheel 14 and the driven support wheel 15;

[0046] Described rolling guide rail pair 35 is connected with described alignment mechanism, and described rolling guide r...

Abstract

The invention provides a polishing device for a heat-isolation material, and a polishing method thereof. The polishing device for the heat-isolation material comprises a base bench system, a limit mechanism, a beam frame reference support system, a guide rail box movement system, a feeding adjustment clamping mechanism, a grinding power head and an electronic control system. According to the polishing device for the heat-isolation material, the polishing position of the grinding power head is strictly limited through the arrangement of the beam frame reference support system, so that more accurate polishing is achieved, and the roundness of the surface of the polished workpiece is improved.

Description

technical field [0001] The invention relates to a grinding technology, in particular to a heat insulating material grinding device and a grinding method thereof. Background technique [0002] When the high-speed flight engine is working, the temperature of the wall surface of the combustion chamber can be as high as 3000K. In order to protect the metal workpieces and electronic equipment outside the engine, it is necessary to coat the outer wall of the combustion chamber and the inner wall of the metal workpiece with heat-resistant heat-resistant materials for thermal protection. After heating the material, the cylindrical combustion chamber and the cylindrical workpiece are assembled. [0003] The outer surface of the combustion chamber and the inner surface of the metal cylindrical workpiece are usually covered with fibrous heat insulating material with certain flexibility, and in order to minimize the gap between the two sets, the outer dimension of the heat insulating ma...
