Embodiment Construction
[0022] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0023] The structure of a hexagonal blind hole rotary cathode electrolytic machining device with anode protection of the present invention is as follows figure 1 As shown, it includes the cathode device of the rotary tool with anode protection, the electrolytic fixture device, the workpiece and the machine tool system. Under the action of the pulse power supply, the filtered electrolyte flows into the cathode of the rotary tool, and the electrolyte is stirred and flows into the processing gap. The flow field is obtained Improve and complete the electrolytic machining of hexagonal blind holes. The cathode device of the rotary tool with anode protection includes a rotary cathode 2 arranged on the main shaft of the machine tool 3, and the liquid inlet pipe 4 is arranged on the rotary cathode 2; 15 is fixed by the first bolt 11 and the second bolt 12, and the wo...

The invention discloses a hexagon blind hole rotating cathode electrolytic machining device with anode protection. A tool cathode device, an electrolytic tool fixture device, a workpiece and a machinetool system are included; a rotatable rotating body is arranged on the tool cathode device, and is provided with liquid passing holes in pairs; and electrolytic liquid is injected into the liquid passing holes to form a pair of force couples, and the rotating body is made to rotate. Under the effects of a pulse power source, the electrolytic liquid after being filtered flows into a rotating toolcathode, and is stirred and flows into a machining gap, a flow field is improved, and a bottom boss is eliminated; and an anode protection device plays a role of restraining stray current, hole wallsof a machined hexagon blind hole are made perpendicular, and electrolytic machining of the hexagon blind hole is completed. The hexagon blind hole rotating cathode electrolytic machining device with anode protection has the beneficial effects of being simple in structure and uniform in flow field, and the hexagon blind hole electrolytic machining precision is high, and wide practical value is achieved.
Description
technical field [0001] The invention relates to an electrolytic processing device, in particular to a hexagonal blind hole cathode electrolytic processing device with anode protection, which belongs to the field of electrolytic processing. Background technique [0002] Electrolytic machining is a processing method in which metal workpieces are used as anodes for dissolution and erosion, and are processed in rows according to the shape of the cathode of the tool. After more than half a century of development since its inception, electrolytic machining has become an important branch in the field of modern machinery manufacturing, and has been widely used in military and civilian industries. Traditional mechanical processing is difficult to process materials with high strength and high hardness, such as cemented carbide and titanium alloys, but electrolytic processing can solve them very well. As an important branch of special machining, electrolytic machining has the advantag...
