Abstract

The invention relates to a regular dodecahedron hollow nesting processing method. A workpiece has a cylindrical structure, the workpiece is put to a die, and processing of ten planes is completed; andthen, a positioning plug is adopted to process a hollow step hole. A special die is designed to position and fasten the shape of the regular dodecahedron, so that the positioning is accurate, the clamping is convenient, and the processing is easy; by designing the positioning plug, deformation and breakage during hollowing-out treatment are avoided; by adjusting the size of the die body and the included angle between two intersecting planes, the method is suitable for processing polyhedral hollow parts with various diameters. The processing method is easy to operate, the processing efficiencyis improved, and the processing cost is saved.

Description

technical field [0001] The invention belongs to the field of mechanical processing, and in particular relates to a processing method for hollow-out nesting of regular dodecahedrons. Background technique [0002] At present, the regular dodecahedron structure is difficult to clamp when using a lathe, and it is difficult to align and position during the process, and the ideal effect cannot be produced by using a general-purpose fixture. When the dodecahedron is hollowed out, the workpiece is deformed and broken during processing because the wall thickness of the part becomes thinner. Contents of the invention [0003] The object of the present invention is to provide a method for hollowing out and nesting regular dodecahedrons, which solves the problem of difficult alignment and positioning in the process of machining the dodecahedron shape, and also solves the problems of deformation and fracture during hollowing out. [0004] The technical solution of the present inventio...
