Problems solved by technology

[0003] However, the design and manufacture of shaped cathodes are difficult, and the manufacturing cycle is long. At the same time, due to the complex shape of the cathode, large processing area, and many influencing factors, the copying accuracy and repeatability of copy processing are not very high.
Especially for the processing of special-shaped cavities on complex mold surfaces or thin-walled integral workpieces, copy-type electrolytic machining is difficult to complete due to the limitation of tool cathode rigidity and processing feed mode.

Abstract

The invention relates to a spherical cathode numerical control electrochemical machining machine tool which comprises a machine tool body. The machine tool body is provided with a linear circular rail. The machine tool body is provided with a workbench. The workbench is provided with an insulating plate. The insulating plate is connected with a machining box in a closed mode. The linear circular rail is provided with a three-axis movement mechanism. A Z-direction movement mechanism and a C-direction rotating mechanism in the three-axis movement mechanism are fixedly connected. The C-direction rotating mechanism is provided with a spherical cathode through a fixture in a clamped mode. The spherical cathode is of a round-rod-shaped structure with a spherical head. The spherical head end of the spherical cathode is provided with a plurality of small holes. The spherical cathode is internally provided with through holes communicated with the small holes. One side of the machine tool body is provided with an electrolyte storage mechanism and a pumping mechanism. The pumping mechanism pumps the electrolyte in the electrolyte storage mechanism to the through holes in the spherical cathode, and then the electrolyte flows out of the small holes. In the flowing out process of the electrolyte, the spherical cathode is driven by the three-axis movement mechanism and the C-direction rotating mechanism to finish machining of workpieces.

Description

technical field [0001] The invention relates to the field of electrolytic machining, in particular to a spherical cathode numerically controlled electrolytic machining machine tool. Background technique [0002] Electrolytic machining technology uses the principle of anodic dissolution of metal in the electrolyte to form parts. Because the tool cathode has no loss, no macro cutting force, it is suitable for processing parts made of various difficult-to-cut materials and has good surface quality. A large number of applications have been obtained in the industry. Traditional electrolytic machining mostly adopts forming cathode copy processing when processing cavity and surface, and complex cavity and surface can be processed with simple feed movement in one direction. [0003] However, the design and manufacture of shaped cathodes are difficult, and the manufacturing cycle is long. At the same time, due to the complex shape of the cathode, the large processing area, and many ...
