Multi-pipe floating complex curved surface self-finding track electrolytic processing device and method

Abstract

The invention relates to a multi-pipe floating complex curved surface self-finding track electrolytic processing device and method, and belongs to the field of electrolytic processing. The method is characterized in that an inner liquid spraying tube electrode group can be floated up and down on the surface of a curved surface part according to a specified processing track under the action of springs and a guide device, and the method can be used for electrolytic processing of workpieces with complex outer surfaces; and in addition, due to the fact that the multi-pipe liquid spraying processing is adopted, the flow field of a processing area is more stable compared with a single-pipe liquid spraying process. The processing device comprises the following components of group tube electrodes,the springs, elastic soft infusion tubes, a clamp body, a guide tube and the like. The method and the device has important significance in improving the electrolytic processing efficiency and stability and reducing the difficulty of programming and operation of numerical control machining the curved surface part.

Description

technical field [0001] The invention relates to a multi-tube floating complex curved surface self-tracking electrolytic machining device and method, belonging to the field of electrolytic machining. Background technique [0002] In aerospace and other fields, in order to meet special functional requirements, some key parts have curved surfaces, such as aero-engine blades, etc., and these parts are mostly made of difficult-to-machine materials such as titanium alloys. The processing of these materials requires post-processing There is no recast layer and microcracks on the surface. In order to meet the above requirements, high-performance CNC machine tools are currently used for high-speed milling of curved surfaces, but high-speed milling requires writing complex CNC programs, consuming (wearing) a lot of diamond tools and requiring high-performance CNC machine tools for a long time, and the processing efficiency is relatively high. Low. Therefore, how to realize high-effi...

Problems solved by technology

[0003] In addition, when the surface shape of the machined part is complex and changeable, it is often necessary to survey and map the surface shape of the part first, or obtain a detailed drawing of the part surface, and then fit the processing path according to the shape of the surface, and then control it under the control of the NC program. Next, the contour of the curved surface is processed by point-by-point scanning. Although the processing accuracy can be guaranteed in this way, it can only be processed point by point for the particularly complex three-dimensional surface contour, so the processing efficiency is very low.
