A Knife Setting Device for Jet Electrochemical Machining

Abstract

A tool setting device for jet electrolytic machining, comprising a cathode nozzle, a tool electrode, a pulse power supply, and a detection and feedback unit; wherein, the cathode nozzle is arranged at the center position directly below the lifting shaft of a machine tool, and the tool electrode is arranged at the lower end of the lifting shaft of the bed The side of the detection and feedback device is connected with the cathode nozzle, the tool electrode and the workpiece, and the pulse power supply is connected with the tool electrode and the workpiece. The distance between the lowermost end of the cathode nozzle and the lowermost end of the tool electrode is adjustable. When setting the tool, the cathode nozzle and the tool electrode move downward with the lifting shaft of the machine tool. When the distance between the tool electrode connected to the pulse power supply and the surface of the workpiece reaches the discharge gap, the voltage between the electrodes breaks down through the air medium to generate spark discharge. The feedback unit buzzes and sends a signal to the lifting axis of the machine tool, the lifting axis of the machine tool stops moving, and the tool setting is completed. The device uses the principle of electric spark discharge to ensure the distance between the cathode nozzle and the surface of the workpiece, so as to improve the precision of tool setting.

Description

technical field [0001] The invention belongs to the field of jet electrolytic machining, and particularly relates to a tool setting device for jet electrolytic machining. Background technique [0002] Jet Electrochemical Machining is a maskless electrolytic machining technology in which cathodic spraying electrolyte impinges on the surface of anode workpiece for localized electrolytic machining. In addition to the advantages of the traditional electrolytic process, this process also has unique advantages such as no mask, low processing cost, and simple process when processing microstructures, so it has gradually become a research hotspot in the field of electrolytic processing. Before ECM, the process of maintaining a certain distance between the cathode nozzle and the workpiece is called tool setting. Tool setting is an important part of the ECM process, and the accuracy of tool setting directly affects the accuracy of ECM. In the existing process, the low-voltage short-ci...
