US 2008/0152446 A1 · Device And Method For Green Machining Bevel Gears

Abstract

The invention relates to a device for green machining bevel gears, comprising an CNC machining station for gear cutting a wheel blank (K2). The machining station comprises a tool spindle which is used to receive a gear cutting tool and a work piece spindle which is used to receive the gear blank (K2). Said machining station also relates to a machining station which operates in a vertical manner. Said device also comprises a vertical processing station having a tool holder and a work piece spindle which is used to receive a work piece blank (K1). The machining station mechanically forms a functional unit together with the pre-machining station, wherein the work piece blank (K1) undergoes green machining in the pre-machining station, and is transferred as a gear blank (K2) to the first machining station after the first green machining where it is cut into a gear. Said machining station and the pre-machining station are linked together in terms of data and control.

Dependent claims

A device for use in the green machining of bevel gears, having a CNC-controlled machining station for gear cutting a gear blank, the machining station having a tool spindle for receiving a gear-cutting tool and a workpiece spindle for receiving the gear blank, characterized in that

the machining station is a vertically operating machining station, in which, during gear cutting, the workpiece spindle having the gear blank is situated below or above the tool spindle having the gear-cutting tool,
the device additionally has at least one vertically operating pre-machining station having a tool holder and a workpiece spindle for receiving a workpiece blank, the machining station forming a mechanical functional unit together with the pre-machining station, in which the workpiece blank experiences first green machining in the pre-machining station, to then be transferred after the first green machining as the gear blank to the machining station and be cut into a gear therein, and the machining station and the pre-machining station being linked to one another by control technology.

A method for green machining bevel gears, having the following steps:

(a) chucking a workpiece blank on a first workpiece spindle of a pre-machining station,
(b) performing first green machining of the workpiece blank using a tool, which is chucked in a first tool spindle of the pre-machining station, to generate a gear blank from the workpiece blank,
(c) automated transfer of the gear blank from the pre-machining station to a machining station, the gear blank being transferred from the first workpiece spindle to a second workpiece spindle of the machining station,
(d) performing second green machining of the gear blank using a tool, which is chucked in a second tool spindle of the machining station, to generate teeth on the gear blank,
the machining station and the pre-machining station being vertically operating stations and the machining station forming a mechanical functional unit together with the pre-machining station.
