Abstract

The invention relates to an inclined hole electrosparking processing device, comprising a joint body, an electrode deflection shaft, a positioning clamping screw, a tightening screw cap, a positioning shaft and a hollow small hole electrode. A connecting rod of the electrode deflection shaft is located in a rectangular slotted hole of the joint body; an equal-diameter end of a positioning shaft is located in a shaft hole of the electrode deflection shaft and is tightened up; a rubber sealing piece is located in the shaft hole of the electrode deflection shaft and the hollow small hole electrode penetrates through a drill chuck and is placed into the positioning shaft. In the invention, according to the inclined angle between the inclined hole and the X axis or Y axis and degree scale on the joint body, the inclined angle beta between the electrode and the X axis or the Y axis is initially adjusted, and the electrode is moved along the negative direction of Z axis or the positive direction of the X axis to obtain the actual inclined angle beta between the electrode and the X axis or the Z axis. In addition, the corresponding position of the inclined hole electrode and the inclined hole center C is identified to obtain coordinates of the Z axis and X axis of a machine tool, so that the problems of the existing small hole electrosparking processing device such as high cost, long cycle, difficult positioning of the electrode and low positional precision of processing holes and the like are solved and 0-90-degree inclined hole electrosparking processing is realized.
