The invention relates to an electrolytic processing device and method for a multi-stage rectifying stator inwardly facing blade, and belongs to the field of electrolytic processing. The processing device includes the following components: an upper fixed frame, a lower fixed frame, a machine tool support, a cathode module, and a fixture, and is characterized in that: the upper and lower fixed frames are combined to form a gantry-shaped structure, one side is connected with the machine tool support, and the other side is placed There is a U-shaped chute on the inner side of the rectifier stator, the cathode is installed in the chute, and the cathode moves outward along the radius of the rectifier stator to realize the processing of the inward blade; the cathode of the tool adopts a modular design, and the cathode module includes a cathode module (cathode module) head, insulating sleeve, fixed block) and the liquid inlet connection seat, quickly disassemble and replace the cathode module on the liquid inlet connection seat, and slide the cathode module along the U-shaped groove to the new processing position, so that the blades of different stages of the rectifier stator can be realized processing. The invention can meet the requirements of electrolytic processing of nesting materials for inward blades, and is of great significance for realizing continuous processing of multi-stage blades on workpieces.
Description
technical field [0001] The invention relates to an electrolytic processing device and method for a multi-stage rectifying stator inwardly facing blade, and belongs to the technical field of electrolytic processing. Background technique [0002] Electrolytic machining is a special machining technique that removes material based on the principle of electrochemical anodic dissolution. During the electrolytic machining process, the cathode of the forming tool is fed to the anode of the workpiece under the control of the numerical control system, and the anode material of the workpiece is gradually dissolved until the shape and size of the anode of the workpiece meet the requirements. This processing method has the characteristics of no loss of tool cathodes and no cutting stress, and has significant advantages in batch processing of difficult-to-cut materials with complex shapes. [0003] Nesting electrolytic machining has the obvious advantages of high efficiency and low cost ...
