Abstract

The invention relates to a servomechanism for milling an electric spark made of a non-conducting material. The servomechanism comprises a servo motor, a speed reducer, a shaft, a sheet storage wheel, a box body and a support frame, wherein the box body is connected and fixed with a machine tool through a bolt; the servo motor is connected onto the speed reducer through a bolt; the speed reducer is connected onto the support frame through a bolt; the support frame is connected onto the box body through a bolt; an output shaft of the servo motor is connected with an input shaft of the speed reducer; the output shaft of the servo motor is connected with the input shaft of the speed reducer; the output shaft of the speed reducer is connected with one end of a coupling; the other end of the coupling is connected with the shaft; a right bearing, a left bearing and the sheet storage wheel are sequentially mounted on the shaft in the direction from the servo motor to the speed reducer; an auxiliary electrode winds the storage wheel; an elastic strip presses the outermost layer of the auxiliary electrode; one end of the auxiliary electrode extends into a guide slot of a guide plate to guide the movement of the auxiliary electrode. The continuous feeding of the auxiliary electrodes can be realized, a continuous and stable conductive layer can be formed when the non-conducting material is processed, and the servomechanism has the advantages of being simple in structure, low in cost and the like.

Description

technical field [0001] The invention belongs to the field of mechanical processing, and in particular relates to a servo device for electric spark milling of non-conductive materials. Background technique [0002] EDM is the local instantaneous high temperature and high pressure generated by the spark discharge between the tool electrode and the workpiece to remove the material. There is no macroscopic force between the tool electrode and the workpiece during processing, and any hard, brittle, tough, soft material can be processed. , High melting point materials. However, since non-conductive materials cannot be directly used as one side of the electrode pair for spark discharge machining, it has brought great difficulties to the development of its electric machining technology. The research on EDM technology of non-conductive materials is a research hotspot in the field of special processing. At present, scholars at home and abroad mainly study high-voltage EDM, electrolyt...
