Problems solved by technology

[0005] In addition, the traditional method of using external nozzles to provide cutting fluid generally requires a separate liquid spray device next to the milling head, which has poor installation and use flexibility; Surface loss, when the processing depth of cut is large, it is difficult for the cutting fluid to fill the entire processing gap in time due to the large flow resistance in the processing gap, resulting in insufficient liquid supply in the processing area, which limits the increase in material removal rate
Therefore, the internal injection liquid supply method is introduced, and the cutting fluid is directly sprayed into the machining gap through the inner hole of the milling head, forming a stable and uniform flow field in the machining gap, which can timely take away the Joule heat and insoluble Products, etc., significantly increase the milling depth and increase the processing area, which is more conducive to the removal of large margins of difficult-to-cut alloys with high efficiency and low cost; For workpieces with multiple gaps, due to the large flow resistance of the cutting fluid in the machining gap and the rotation of the electrode milling head during processing, when the internal spray system is used alone, a large amount of internal spray cutting fluid will be quickly lost in the processed area, resulting in a gap in the machining gap. The reduction of the cutting fluid flow rate and the uneven distribution of the flow rate in the interior will easily lead to poor processing stability and is not conducive to improving the processing efficiency; the effective combination of the internal spray liquid and the external spray liquid can be adjusted according to the actual processing situation, and can be mutually How to quickly and conveniently realize the combination of internal spray liquid and external spray liquid supply is also the core problem to be solved by the electrode milling head installation device

Description

technical field [0001] The invention relates to the technical field of electrolytic spark milling, in particular to a multifunctional milling head installation device for electrolytic spark milling. Background technique [0002] At present, for the integral components of difficult-to-cut materials such as titanium alloys and high-temperature alloys, the commonly used manufacturing processes include CNC milling, EDM, and electrolytic machining. When EDM is used, not only the processing efficiency is still limited, but also the recast layer, heat-affected zone and micro-cracks are easily formed on the workpiece processing surface, which will affect the fatigue strength and working life of the overall component. Although electrolytic machining has the advantages of no tool cathode loss, high machining efficiency, and stress-free machining, a passivation film with high resistance and dense structure is easy to form on the surface of the workpiece during the anodic dissolution pr...
