Floating tool electrolytic turning and grinding integrated machining method and implementation device

Abstract

The invention discloses a floating tool electrolytic turning and grinding integrated machining method and implementation device, and belongs to the technical field of electrolytic mechanical combinedmachining. The method is characterized in that a tool grinding head is driven by a compression spring to make flexible contact with the surface of a rotary workpiece, controllable adjustment of electrolysis and grinding effects is achieved, the service life of the tool grinding head is prolonged, and the rotary workpiece machining precision is improved; the tool grinding head reciprocates at a high speed relative to the axial direction of the rotary workpiece, so that discharge of electrolysate in a machining area is promoted, and a good microscopic leveling effect on the surface of the rotaryworkpiece is achieved; and high-pressure air flowing in a rotating mode is introduced into a non-machining area of the rotary workpiece, diffusion and flowing of electrolyte to the non-machining areaare blocked, and locality of electrolytic turning and grinding integrated machining is improved. The implementation device comprises a rotary ventilation device, an electricity and flow leading device, the rotary workpiece, the tool grinding head and a tool clamp. The method and the device are of great significance in improving the electrolytic turning and grinding integrated machining precisionand the microscopic leveling effect of the rotary workpiece.

Problems solved by technology

[0009] Although the above-mentioned electrolytic mechanical composite processing method can effectively improve the surface quality of the workpiece, most of the rotating tool and the workpiece are in rigid contact during the processing process, so it is difficult to stably adjust the grinding force, and it is also difficult to stably control the grinding scraping and electrochemical dissolution.

When the grinding effect is too strong, it is easy to accelerate the loss of the tool grinding head and reduce its service life; while the electrolytic effect is too strong, it is easy to cause serious stray corrosion, and it is difficult to completely remove it by subsequent mechanical grinding
