Problems solved by technology

During the moving process of the test probe, the processing machine tool records its movement space coordinates, and then the test probe moves to the small hole on the surface of the workpiece through the conduction detection power perception to complete the determination of the starting position of the capillary electrode electro-hydraulic beam machining. It solves the problem that the capillary electrode in the prior art is fragile, and it is not easy to accurately control the initial gap, so that it is impossible to accurately locate the initial position of the electro-hydraulic beam processing of the capillary electrode

Abstract

The invention relates to a device and method for determining the starting position of capillary electrode electrohydraulic beam machining. The determining device includes: a test probe, a capillary electrode, a conduction detection power supply, and a processing machine tool; the test probe and the capillary electrode are respectively arranged on the processing machine tool, and move under the control of the processing machine tool; One power end of the conduction detection power supply is respectively connected to the test probe and the capillary electrode, and the other power end of the conduction detection power supply is connected to the workpiece to be processed; the processing machine tool is connected to the conduction detection power supply connected, and when the two power terminals of the conduction detection power supply are conducted, it transmits the conduction signal to the processing machine tool. The invention automatically and accurately reserves the initial gap, which plays a key role in ensuring the consistency of the entrance shape of the small hole, and the processed small hole entrance has good consistency and the effect is remarkable.

Description

technical field [0001] The invention relates to the technical field of electro-hydraulic beam machining, in particular to a device and method for determining the starting position of capillary electrode electro-hydraulic beam machining. Background technique [0002] Electrochemical pore making of small holes generally uses a capillary glass tube as an electrode, and the acid liquid passes through the electrode to form a liquid beam, and under the action of electrochemical anode dissolution, the processing of the metal workpiece is realized. The cold working characteristics of electrohydraulic beam machining guarantee in principle that there is no recast layer, no microcracks and no heat-affected zone on the metal processing surface. In recent years, my country has made major breakthroughs in many key technologies of electro-liquid beam technology and equipment. Electro-liquid beam processing technology tests have been carried out on various metal materials and high-temperatu...
