Abstract

The invention discloses a micro-fine tapered electrode electric spark reverse copying device. The micro-fine tapered electrode spark reverse copying device comprises an electric spark reverse copyingelectrode, and further comprises a base. The spark reverse copying electrode comprises a first electrode body and a second electrode body, and the first electrode body and the second electrode body are correspondingly connected to the base through one ends of the first electrode body and the second electrode body and are mounted on the base. The first electrode body and the second electrode body are provided with inclined surfaces, the inclined surface on the first electrode body is in directly facing relation with the inclined surface on the second electrode body, and the two inclined surfaces are in a plane symmetry relation. A gap is formed between the two inclined surfaces as a reverse copying channel. The inclined direction of the inclined surfaces is inclined from the end, away fromthe base, of the first electrode body or the second electrode body to the end where the base is located, and the inclined surfaces are inclined relative to symmetry planes for forming the plane symmetry relation of the two inclined surfaces. The reverse copying device can be used for micro-fine tapered electrode machining, does not need expensive online detection equipment in the machining process, and meanwhile, the micro-fine tapered electrode spark reverse copying device is easy to operate during use.

Description

technical field [0001] The invention relates to the technical field of micro-electric discharge machining, in particular to a micro-conical electrode electro-spark reverse copying device. Background technique [0002] With the rapid development of aviation, aerospace, microelectronics, precision instruments and other fields, the demand for high-precision and high-quality miniaturized products is becoming increasingly urgent, and micro-processing technologies such as micro-EDM are becoming more and more widely used. Micro electrodes have broad application prospects in the field of micro electric discharge machining of difficult-to-machine materials. Micro-electrodes are prepared by machining methods such as precision grinding, turning, and milling. Due to the existence of cutting force, the micro-electrodes are easily deformed or broken under force. As a non-contact processing method, EDM can effectively avoid the problems in the above-mentioned mechanical processing methods...
