Abstract

The invention belongs to the technical field of machining, particularly relates to a combined machining tool for molded surfaces of deep cavities among drum webs and a machining method of the combined machining tool. By the combined machining tool, the technical problems of vibration, tool collision and poor surface quality during machining of the molded surfaces of the deep cavities among the drum webs of aero-engines are solved. The combined machining tool comprises a middle plate-shaped tool, an upper plate-shaped tool and a lower plate-shaped tool. The machining method includes the following steps: step 1, fixedly connecting a transfer tool with a numerically-controlled vertical turning tool clamp; step 2, machining middle molded surfaces of the deep cavities among the drum webs; step 3, machining upper molded surfaces and upper arc-shaped molded surfaces of the deep cavities among the drum webs; step 4, machining lower molded surfaces and lower arc-shaped molded surfaces of the deep cavities among the drum webs to complete machining of primary inner cavities; step 5, circularly performing the step 2 to the step 4 to sequentially complete machining of each-level inner cavities.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing, and in particular relates to a combined processing tool and a processing method for deep cavity profiles between drum webs. Background technique [0002] In the processing and manufacturing of aero-engine drum parts, in order to improve the performance of the engine and meet the work requirements, the deep cavity profile between the webs of the drum needs to be combined. Life and safety, high requirements on surface quality. Due to the narrow space of the deep cavity between the webs and the large radial depth, limited by the structure, the strength of the cutting tool is low, and it is easy to generate vibration and knife hitting during machining, resulting in ripples on the machined surface, and poor surface quality after machining, which has always been a problem. Critical technical issues for parts delivery. [0003] The new generation of aero-engine drum assembly is the key p...
