Abstract

The invention provides an ellipsoidal spiral surface profiling mechanism. The ellipsoidal spiral surface profiling mechanism comprises a lever zooming unit, a lever reverse dialing unit, a template ellipsoidal movement unit and a workpiece blank movement unit. The template ellipsoidal movement unit comprise a template ellipsoid and an axial limiting rolling body assembly, and the axial limiting rolling body assembly leans against the template ellipsoid; the template ellipsoid is provided with first axis and can move linearly along the first axis under the action of the axial limiting rolling body assembly while rotates around the first axis; the workpiece blank movement unit comprises a workpiece blank which is provided with second axis parallel to the first axis, the workpiece blank can move linearly along the second axis while rotates around the second axis, and rotation of the workpiece blank and that of the template ellipsoid are synchronized, so that the shape of the template ellipsoid is reflected to a working end to realize precise profiling.

Description

technical field [0001] The invention relates to a profiling mechanism, in particular to an ellipsoid spiral curved surface profiling mechanism and a control method thereof. Background technique [0002] The existing profiling usually adopts two basic technologies, one is to simulate in a one-to-one ratio, such as using a mechanical profiling mechanism and a ball-end cutter to process the profiling of the working surface of the mold; the other is to use a template to shape the workpiece Simulated machining of surfaces. Usually, when the above-mentioned profiling technology is used, the geometry of the cutter head directly affects and limits its working path and the fineness of profiling. [0003] Therefore, the present invention provides an ellipsoidal spiral curved surface profiling mechanism and its control method. The spherical shape can be accurately mirrored to the working end through the lever type scaling mechanism to realize profiling. Contents of the invention ...
