Abstract

The invention provides an electrosparking head device which comprises a lower rack (3), an upper rack (6) and an inner rack (1), wherein the upper rack (6) is positioned above the lower rack (3); the inner rack (1) is positioned in a chamber formed by the lower rack (3) and the upper rack (6) and can slide up and down; the inner side of the upper part of the upper rack and the upper side of the inner rack (1) are respectively provided with an electromagnetic coil (62) and a magnet (63) which are coupled with each other so as to drive the inner rack (1) to slide; the lower parts of two side walls of the lower rack are symmetrically provided with an upper wedge surface locating pin (31) and a lower wedge surface locating pin (32) in each side wall; the lower parts of two sides of the inner rack (1) are respectively, correspondingly and symmetrically provided with an upper cotterway and a lower cotterway; when the inner rack (1) is in an upper working state, the upper wedge surface locating pin (31) is matched with the upper cotterway.

Description

technical field [0001] The invention relates to the field of electric discharge machining, in particular to an electric discharge machining head device. Background technique [0002] EDM is a special processing method that uses the electric erosion effect generated by the pulse discharge between the two electrodes immersed in the working fluid to erode conductive materials, also known as electric discharge machining or electric erosion machining. [0003] During EDM, the tool electrode and the workpiece are respectively connected to the two poles of the pulse power supply, and immersed in the working fluid, or the working fluid is filled into the discharge gap. The tool electrode is controlled to feed to the workpiece through the gap automatic control system. When the gap between the two electrodes reaches a certain distance, the pulse voltage applied to the two electrodes will break down the working fluid and generate spark discharge. A large amount of heat energy is conce...
