Elongated precise thin-wall aluminum alloy pipe inner hole polishing and grinding tool and method

Abstract

The invention relates to an elongated precise thin-wall aluminum alloy pipe inner hole polishing and grinding tool and method, and belongs to the technical field of pipe inner hole polishing and grinding. The elongated precise thin-wall aluminum alloy pipe inner hole polishing and grinding tool comprises a grinding head assembly (1), a connecting head (2), a sealing head (3), a protective rubber ring (4), a grinding rod (5) and a liquid passing valve (6). According to the elongated precise thin-wall aluminum alloy pipe inner hole polishing and grinding tool and method, a pipe is driven througha driving mechanism to rotate, the grinding head assembly (1) performs rotating and feeding to polish and grind an inner hole of the pipe; meanwhile, a cooling liquid is introduced through the liquidpassing valve (6), an inner hole of the grinding rod (5) and a water outlet of the connecting head (2) for lubricating and cleaning to eliminate polishing and grinding metal scraps and particles, abrasive paper with corresponding particle size replaces old abrasive paper according to the required roughness, the required surface technical requirements can be met, the problem of polishing and grinding of the inner hole of the elongated precise thin-wall aluminum alloy pipe is solved, the manufacturability is good, and the polishing and grinding quality is stable.

Description

technical field [0001] The invention relates to a slender precision thin-wall aluminum alloy pipe inner hole polishing tool and method, belonging to the technical field of pipe inner hole polishing. Background technique [0002] Slender and thin-walled precision aluminum alloy pipes are mainly used for aerospace structural parts and airborne products due to their high specific strength. However, the processing accuracy, surface quality, and flaw detection level of the pipe are strictly required, especially the quality of the inner hole cannot be guaranteed, which affects the surface quality and flaw detection of the pipe, and the product qualification rate is extremely low. The aluminum alloy pipe is formed by deformation processing. The ellipticity of the pipe is large, and the deviation of the wall thickness is strict. The traditional mechanical honing method will cause the ellipticity to be corrected, resulting in unqualified wall thickness; The grinding effect cannot me...

However, the processing accuracy, surface quality, and flaw detection level of the pipe are strictly required, especially the quality of the inner hole cannot be guaranteed, which affects the surface quality and flaw detection of the pipe, and the product qualification rate is extremely low.

The aluminum alloy pipe is formed by deformation processing. The ellipticity of the pipe is large, and the deviation of the wall thickness is strict. The traditional mechanical honing method will cause the ellipticity to be corrected, resulting in unqualified wall thickness; The grinding effect does not meet the technical requirements
