Electromechanical finishing method for pulling flexible tool cathode and inner channel

Abstract

The invention relates to a traction flexible tool negative pole and an internal channel electrolytic mechanical finishing method and belongs to the field of electrolytic milling and grinding compositeprocessing. The tool negative pole includes a negative pole bolt and a flexible friction layer. Before processing, one end of a metal wire is connected with a small ball, the small ball drives the metal wire to pass through the entire internal channel under the washing pressure of electrolyte, and then the two ends of the metal wire are correspondingly fixed on a pay-off rotating shaft and a take-up rotating shaft. During processing, the pay-off shaft pays off, the take-up shaft takes up, the metal wire moves and drives the tool negative pole to move in the internal channel of a workpiece, and then the inner wall surface of the channel is leveled under the combined action of electrolysis and friction. By the adoption of the novel tool negative pole form and movement mode, the flexibilityof electrolytic machining is improved, and it is ensured that the tool negative pole can smoothly machine any wall surface of the internal channel of the workpiece, so that efficient electrolytic mechanical finishing of the internal channel of the component is realized.

Description

technical field [0001] The invention relates to an electrolytic mechanical finishing method for a cathode of a traction type flexible tool and an internal channel, and belongs to the field of electrolytic milling and grinding composite processing. Background technique [0002] The use of integral components can save the connectors between parts, reduce the number of parts, significantly reduce the weight of components, and greatly improve the overall performance of the product. Therefore, it has been used in aerospace, automotive, and weaponry. more and more applications. For example, the cockpit radio shield, landing gear shield and air intake support columns on the British Tornado fighter jets all use integral components. However, for some monolithic components with complex internal channels, such as rocket engine nozzles, due to their narrow and curved channels, conventional processing is difficult and inefficient. Therefore, realizing efficient and fast processing of i...
