Description

technical field [0001] The invention relates to an electrochemical machining device, in particular to a tool cathode for electrolytic machining of a special-shaped cavity and a clamping method. Background technique [0002] For workpieces with conventional shapes such as round and square structures, low-cost, high-efficiency, and high-precision components can be obtained through traditional processing methods, but it is more difficult for irregular shapes such as special-shaped holes and special-shaped cavities. Traditional machining methods, for special-shaped cavities, especially thin-walled ones, when milling is used, the residual stress is likely to cause micro-deformation of the structure, resulting in a large shape and position error; for special-shaped holes, traditional drills cannot achieve holes The shape requirements of the machining, and the difficulty of chip removal and severe heat generation during the drilling process cannot be used as an ideal processing met...

Problems solved by technology

Although the above-mentioned patent avoids the design and manufacture of the external liquid supply nozzle and its related fixtures, reduces the complexity and cost of the process, and ensures the dimensional accuracy and surface quality of the electrolytic turning repair, but if the above-mentioned device is intended to be used for various axes The electrolytic turning repair of similar parts still needs to disassemble the tool cathode, which cannot adapt to the electrolytic machining of small batches or single-trial workpieces, and the efficiency is low
