Rotary electrolytic machining grooving method and device

Abstract

The invention provides a rotary electrolytic machining grooving method and device. The rotary electrolytic machining grooving device is characterized by comprising a machine tool, a machine tool spindle, a servo motor, sliding rings, a direct-current power supply, a tool electrode, a workbench, a workpiece, an electrolytic tank, an electrolyte, a field-effect tube module and a plurality of connecting wires, wherein the tool electrode is installed on the machine tool spindle, the tool electrode is composed of four small electrodes, the small electrodes are connected with a negative electrode ofthe direct-current power supply through the sliding rings and field-effect tubes, and are uniformly distributed and installed on an insulating plate, the small electrodes are insulated from one another, moreover, the four sliding rings are also insulated from one another, each power supply sliding ring is only connected with the corresponding small electrode, and is insulated from the other threesmall electrodes, and the on-off state of the field-effect tube module is controlled by a controller so as to determine whether each small electrode is connected with the direct-current power supplyor not. The rotary electrolytic machining grooving method and device are simple and effective, and the problems that in the prior art, an tool electrode is difficult to manufacture, and an electrolytic product is difficult to remove are solved.

Description

technical field [0001] The invention relates to the field of electrolytic machining, in particular to a method and device for slotting in rotary electrolytic machining. Background technique [0002] During electrolytic machining, the workpiece is connected to the positive pole of the DC power supply, the tool electrode is connected to the negative pole of the DC power supply, and a small machining gap is maintained between the tool and the workpiece. The tool and the workpiece are placed in an insulating fixture, and the electrolyte with a certain pressure flows through the machining gap. The electrolysis products are flushed out of the machining gap by the electrolyte. The tool electrode is fed to the workpiece, and the surface of the workpiece is continuously eroded by electrolysis, and the surface of the workpiece gradually forms a shape similar to that of the tool electrode. Electrolytic machining has been applied in the fields of aviation, military industry, and machin...

Problems solved by technology

Electrolytic machining has been applied in the fields of aviation, military industry, and machinery manufacturing. However, electrolytic machining of long grooves faces many difficulties, such as difficulty in making tool electrodes, requiring high-power electrolysis power supply, difficulty in fixture design, and difficulty in uniform electrolyte pressure in the machining gap. Difficult problems such as distribution and electrolysis products are difficult to exclude
