Abstract

The invention discloses a fixture device and method for efficient electrolytic slotting machining of a blisk, and relates to the technical field of electrolytic machining. The device comprises a multi-tool synchronous collaborative feeding device and a follow-up steady-flow liquid sealing device, according to the multi-tool synchronous collaborative feeding device, through a transmission mechanism comprising a synchronous belt, a plurality of synchronous wheels arranged in a layered and staggered mode and idle wheels, rotation of a center main shaft can be converted into synchronous deflection motion of a plurality of pipe electrodes, and single-shaft input and multi-shaft output are achieved. According to the follow-up type steady-flow liquid sealing device, a top cover plate rotates along with a blade disc workpiece through electromagnetic adsorption, meanwhile, a side face baffle and a pipe electrode follow-up, in this way, follow-up type steady-flow liquid sealing is formed, the flow field mode that side face liquid outlet is combined with top liquid outlet is adopted, and the electrolyte flow field of blade grid channel electrolytic machining is improved. And under the action of electrochemical reaction anode dissolution, simultaneous electrochemical machining forming of the multiple blade grids is achieved. According to the invention, precise and stable electrolytic machining is realized while the machining efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of electrolytic machining, in particular to a fixture device and method for high-efficiency electrolytic grooving machining of an integral blisk. Background technique [0002] The integral blisk is one of the indispensable parts in aero-engines. It makes the blade and the hub as a whole, replacing the tenon and tenon structure used in the traditional blisk, which reduces the number of parts and the overall weight. At the same time, it also has high work efficiency and thrust-to-weight ratio. However, the overall blisk channel is narrow, the profile is complex, the processing precision is high, and the materials are mostly difficult to process, which brings great difficulties to the processing and manufacturing. [0003] Electrolytic machining is an advanced manufacturing technology that uses the principle of electrochemical dissolution of anode metal to remove materials. Because of its advantages of no tool...

Problems solved by technology

However, the increase in the number of tool electrodes will inevitably affect the design of the flow field of each electrode, which will lead to changes in fixtures. Therefore, it is necessary to further design a set of equipment suitable for multi-electrode electrolytic slotting while rationally designing multi-tool synchronous and cooperative motion devices.
