Problems solved by technology

[0006] In the processing tools described in the above-mentioned JP-A-2012-45687 and JP-A-2005-66815, there is a limit to the shortening of the processing time because rough machining is performed sequentially to finish machining.
In addition, the processing tool described in Japanese Patent Application Laid-Open No. 2005-66815 is a tool for planer processing, and cannot be used for cutting by synchronously rotating the processing tool and the workpiece described in Japanese Patent Application Laid-Open No. 2012-45687. method of machining to make teeth

Embodiment Construction

[0023] As an example of a gear processing device, a 5-axis machining center is used as an example. Refer to figure 1 Be explained. In other words, this gear machining device 1 is a device having three translation axes (X, Y, Z axes) and two rotation axes (A axis, C axis) orthogonal to each other as drive axes.

[0024] like figure 1 As shown, the gear processing device 1 includes a base 10 , a column 20 , a saddle 30 , a rotating spindle 40 , a table 50 , an inclined table 60 , a turntable 70 , a control device 100 , and the like. In addition, although illustration is omitted, a known automatic tool changer is provided in parallel with the base 10 .

[0025] The base 10 has a substantially rectangular shape and is placed on the ground. A cylinder 20 is provided on the upper surface of the base 10 , and the cylinder 20 is movable in the X-axis direction relative to the base 10 . A side surface (sliding surface) 20a parallel to the X-axis of the column body 20 is provided wi...

Abstract

A gear machining apparatus includes a machining tool having a plurality of protruding tool edges on an outer periphery of the machining tool, and driving apparatuses that form a tooth on a work piece by rotating the machining tool around a central axis thereof, rotating the work piece W around a central axis thereof, and moving the machining tool relative to the work piece. Radial outer faces of the protruding tool edges form multiple steps that are parallel to the central axis of the machining tool such that the diameter of the machining tool increases in a stepwise manner from a tool leading end toward a tool base end of the machining tool.

Description

[0001] This application claims the priority of Japanese Patent Application No. 2015-137636 filed on July 9, 2015, and uses the entire content including the specification, drawings, and abstract of the specification here. technical field [0002] The invention relates to a gear processing device. Background technique [0003] As an effective method of manufacturing internal or external teeth on a workpiece by cutting using a machine tool such as a machining center, there is, for example, a machining method described in JP-A-2012-45687. In this machining method, a machining tool rotatable around a central axis (tool axis) and a workpiece rotatable around a central axis (workpiece axis) inclined at a predetermined angle relative to the tool axis of the machining tool are rotated synchronously, and the A machining method in which the machining tool is fed multiple times in the axial direction of the workpiece and cut to produce teeth. [0004] The machining tool used in this ma...
