Cam expansion rotating tool cathode for electrolytic machining

Abstract

The invention relates to the technical field of electrolytic machining, in particular to a cam expansion rotating tool cathode for electrolytic machining, and solves the problems of difficult machining of inner wall structures with higher machining depth requirements, weak machining precision and low machining efficiency in the prior art. The cam expansion rotating tool cathode for electrolytic machining comprises a cathode mounting frame; the cathode mounting frame is arranged at the upper part of a base, and is connected with the base through a double-head screw rod; a camshaft is arranged in the center of the base, and is provided with three cams; conical roller bearings are arranged between the camshaft and the base, and are arranged on shaft necks on the two sides of the camshaft; anoutput shaft of a stepper motor is connected with the camshaft through a key; the horizontal rotation of the camshaft in the base is realized; the base is annular; transverse step through holes corresponding to arc working surfaces one to one are uniformly formed in the annular base; step-shaped push rods are arranged in the through holes; and the arc working surfaces are uniformly distributed onthe periphery of the base, and are fixedly connected with the push rods.

Description

technical field [0001] The invention relates to the technical field of electrolytic machining, in particular to a cathode of a cam-expanding rotary tool for electrolytic machining. Background technique [0002] In aviation, aerospace, weapons, petroleum and other fields, there are complex inner wall structures on the key parts of more difficult-to-machine metal materials. For example, oil pipelines are often designed with multiple sets of annular groove structures with different depths and different diameters, which are of great significance for the sealing of the end face of the pipeline interface. On the premise of satisfying the mechanical properties, it can effectively improve the sealing reliability. Due to the difficulty in cutting materials, the machining efficiency of boring and other processing methods is low, the tool wear is serious and the accessibility is poor, the concentricity is affected by tool change, there is macro cutting stress, and there are problems su...
