Internal injection liquid electrolytic crawler grinding composite machining tool cathode and method

Abstract

The invention relates to an inner liquid spraying electrolysis track-type grinding combined machining tool cathode and a method and belongs to the field of electrolysis machining. The inner liquid spraying electrolysis track-type grinding combined machining tool cathode and the method are characterized in that a grinding liquid conveying track is installed on the side wall of a box-shaped hollow electrode; the surface of a track is provided with liquid passing holes and abrasive particles, and electrolysis machining efficiency is improved; a servo motor is arranged at the top of the box-shapedhollow electrode and can drive the track to rotate at a low speed to grind the surface of a part, so that residual mechanical particles and passivation films during high-speed electrolysis machiningare removed, and efficient electrolysis machining is facilitated; when the track rotates, the abrasive particles on the track scratches electrolysate ceaselessly, under washing of an electrolyte, theelectrolysate is washed away fast, and the machining process is more stable. The machining device comprises the following components of a servo motor, the replaceable track, the box-shaped hollow electrode, an industrial personal computer, an electrolysis machining machine tool, a high-power direct-current power source and an electrolyte circulation system. The inner liquid spraying electrolysis track-type grinding combined machining tool cathode and the method has significance for the effects that electrolysis machining efficiency is improved, the electrolysate is discharged fast, and efficient and fast electrolysis machining is ensured.

Description

technical field [0001] The invention relates to a cathode and a method of an internal spray liquid electrolytic crawler grinding composite processing tool, which belong to the field of electrolytic processing. Background technique [0002] In aerospace and other fields, in order to ensure the strength, hardness and other properties of parts, the materials used are mostly difficult-to-machine materials such as titanium alloys, which are difficult to form by traditional cutting; in addition, many parts require a large amount of material removal , The material removal rate of some parts is as high as 90%. Using traditional CNC milling to remove so much material not only needs to wear a large number of high-strength diamond tools, but also needs to occupy high-end machine tools for a long time, resulting in low processing efficiency and high processing costs. Therefore, how to realize high-efficiency and high-quality processing of difficult-to-machine materials for aerospace par...

Problems solved by technology

When the part works under harsh conditions for a long time, the microcracks will expand and eventually lead to the fracture of the whole part

In addition, the traditional electrolytic grinding process uses a grinding wheel to grind the surface of the workpiece, and the liquid is supplied by external spraying, the product is not easy to discharge, and the processing stability is poor

Recently, some scholars have proposed a kind of electrolytic grinding and milling processing technology, which is a technology similar to CNC milling, which is processed by the joint action of the rotation motion of the tool cathode and the feed motion of the workpiece. A composite processing method for metal materials, compared with traditional cutting and grinding, the material removal rate has been significantly improved, but the efficiency of this technology still needs to be improved when processing large-scale horizontal or inclined surfaces, and two adjacent There are traces of the knife at the place where the knife is taken
