Electrolytic machining device and machining method thereof

Abstract

The invention relates to the technical field of machine manufacturing non-traditional machining, in particular to an electrolytic machining device and a machining method thereof. The electrolytic machining device comprises a power source and a cathode guide rod, the cathode guide rod is provided with a hollow cavity for allowing an electrolyte to flow, a liquid inlet communicating with the hollow cavity is formed in one end of the cathode guide rod, and the other end of the cathode guide rod is sealed. A tool electrode and a baffle ring are arranged on the outer wall of the cathode guide rod, the tool electrode is connected with the baffle ring, multiple liquid spraying openings communicating with the hollow cavity are formed between the tool electrode and the baffle ring, a negative electrode of the power source is connected with the cathode guide rod, and a positive electrode of the power source is connected with a workpiece. In the electrolytic machining device, the electrolyte can only be directly sprayed to a machining area from the liquid spraying openings between the tool electrode and the baffle ring, the flow speed of the electrolyte in the machining area is increased, the machining efficiency and the machining quality of electrolytic machining are greatly improved, and the tool electrode can be designed into different shapes according to needs so as to machine inner gear grooves, key grooves and other workpieces in different shapes.

Description

technical field [0001] The invention relates to the technical field of special machining in mechanical manufacturing, and more specifically, to an electrolytic machining device and a machining method thereof. Background technique [0002] Internal gear transmission has a series of advantages such as compact structure and high transmission efficiency, so it is widely used in mechanical transmission devices. However, due to the limitation of the structure of the internal gear itself, most internal gears can only be processed by traditional processing technology. The processing accuracy of traditional processing technology often fails to meet the requirements, which directly affects the quality of gear transmission. The traditional processing techniques of internal gears include gear shaping and broaching. [0003] Gear shaper processing is to process gears according to the generation method. The gear shaper cutter and the gear to be processed move according to the meshing rel...

Problems solved by technology

In this scheme, the electrolyte enters the inner cavity of the workpiece through the bottom of the machining shaft. After filling the inner cavity, the workpiece acts as an electrolytic anode, and the protruding tooth acts as an electrolytic cathode. The inner keyway is electrolytically processed, and the flow rate of the electrolyte is lost, resulting in poor processing quality and low efficiency.
