Abstract

A method for turning and milling to realize typical characteristics of an aircraft landing gear includes the steps: firstly, orthogonal turn-milling for rough machining; secondly, milling to remove intermediate allowance of a lug; thirdly, fine trimming of the bottom of the lug; fourthly, milling of the periphery of the lug; fifthly, fine trimming of the top of the lug; sixthly, semi-finish machining of the inner wall of the lug; seventhly, semi-finish machining and finish machining of the outer wall of the lug; eighthly, finish machining of the inner wall of the lug; and ninthly, finish machining of an outer cylindrical surface. The method mainly aims to realize the common lug characteristics of parts of the landing gear to solve problems in machining the parts. The technological method has the advantages that machining efficiency and the quality of surfaces of workpieces can be effectively improved, and simultaneously, machining is lowered. In addition, the method has an actual reference value in the field of machining process.

Description

(1) Technical field:

[0001] The invention relates to a processing technology, in particular to a typical feature turning and milling processing method of an aircraft landing gear. It belongs to the technical field of mechanical processing technology. (two) background technology:

[0002] In recent years, with the increasingly complex products and higher production efficiency requirements, especially military products such as aviation and aerospace, their shapes have become more and more complicated, and the requirements for precision and efficiency have also become higher and higher. Typical and traditional Turning and milling have been difficult to meet the requirements. Therefore, the turning and milling compound machining center came into being. The turning-milling compound machining center can realize one-time clamping of complex parts and complete all processing procedures, which can greatly improve production efficiency and processing accuracy. At present, the appli...
