Abstract

The invention discloses a tool for achieving integrated electrolysis machining of a complex profile blisk, a blade basin, a blade back and a hub by means of multi-axis linkage of a curved cathode, andrelates to the technical field of electrolytic machining. The tool comprises a rotary workbench, a workpiece clamp mounted on the rotary workbench, a cathode body located at workpiece grid channels,a feeding mechanism capable of performing multi-axis action, a connecting rod for connecting the curved cathode with a machining main shaft and a tool-setting block. The cathode body is of a hollow thin-wall structure, and the geometry of the cathode body is designed according to the grid channels and the hub profile. During machining, the rotary workbench drives a workpiece to do rotary action, the machining main shaft of the feeding mechanism drives the cathode body to move, rotate and the like to form multi-axis linkage, and a blisk workpiece with a complex twisted shape is obtained. The machining method has wide applicability, and the blisk workpiece with high dimensional precision and high surface quality for an aerospace engine can be obtained through one-time machining.

Description

technical field

[0001] The invention belongs to the technical field of electrolytic machining, and in particular relates to a method for integral electrolytic machining of a blisk and an electrolytic tool. Background technique

[0002] As the core component of the aircraft, the performance of the aero-engine will directly affect the overall performance of the aircraft. The blisk is one of the indispensable parts of the aero-engine. The blades of the traditional blisk are connected with the disc through mortise and mortise. Its structure is complex and its life is short, which is difficult to meet the development of the advanced aviation industry. Integral blisks combine blades and discs as a whole, which overcomes the above disadvantages and also has high working efficiency and thrust-to-weight ratio. However, due to the use of difficult-to-machine materials, complex profiles, and high machining accuracy requirements, the machining and manufacturing of blisks has become a w...
