Honing machining method for inner hole net patterns of aero-engine actuator cylinder

Abstract

The invention discloses a honing machining method for inner hole net patterns of an aero-engine actuator cylinder. The method comprises the following steps that 1, a tool is taken and installed on a honing machine; 2, a to-be-machined part is taken, placed on the tool and aligned, and then the aligned to-be-machined part is subjected to flexible press fitting and stabilized on the tool; 3, the honing machine is operated to conduct crude honing machining and fine honing machining on the to-be-machined part in sequence, a honing technology is adopted for uniformly machining deep grooves and small platforms, cross grain surfaces meeting the technological requirement are generated, and during machining, honing cooling liquid is adopted for cooling. Through the mode, the honing machining methodcan improve the sealing performance of the aero-engine actuator cylinder, and the service life is prolonged.

Description

technical field [0001] The invention relates to the field of aero-engine actuator processing, in particular to a method for honing the inner hole of the aero-engine actuator. Background technique [0002] At present, the inner hole of the domestic aero-engine cylinder usually needs surface treatment, chrome plating or hard anodizing after finishing, and then the grinding process is used to achieve the required surface quality and precision requirements. Grinding technology is one of the important means of precision machining, but its processing efficiency is low, labor intensity is high, and the operator needs considerable technology and experience; after grinding, the size dispersion is large; when manual grinding, the abrasive particles will be on the window of the hole, straight Grooves, ring grooves, etc. are damaged, forming grinding shoals; the abrasive paste will also pollute the surface of the parts, making it difficult to clean the surface, and the cleanliness often...

Problems solved by technology

Grinding technology is one of the important means of precision machining, but its processing efficiency is low, labor intensity is high, and the operator needs considerable technology and experience; after grinding, the size dispersion is large; when manual grinding, the abrasive particles will be on the window of the hole, straight Groove, ring groove, etc. cause damage, forming grinding shoals; abrasive paste will also pollute the surface of parts, making it difficult to clean the surface, and the cleanliness often exceeds the standard; the surface morphology of grinding is uneven and inconsistent

The above factors lead to a large gap between the product quality of my country's aero-engine cylinder and other dynamic seals compared with similar foreign parts.
