Abstract
Bevel gear cutting machine for chamfering and/or deburring edges on the teeth of a bevel gear. The gear-cutting machine comprises a workpiece spindle, which receives the bevel gear coaxially of a spindle axis. Furthermore, a deburring spindle is provided for the receiving of a deburring tool and several numerically controllable axes are given. A deburring blade head with several blade cutter-like blade inserts serves as deburring tool, whereby the blade inserts are insertable in recesses of the deburring blade head essentially radially oriented to a deburring spindle axis (E) and comprise edges for chamfering and/or deburring.
Claims12
A bevel gear cutting machine for chamfering and/or deburring edges of the teeth of a bevel gear in a continuous process, said machine having a plurality of numerically controllable axes and comprising:
- a workpiece spindle, which receives the bevel gear coaxially of a workpiece spindle axis,
- a deburring spindle having a deburring spindle axis generally orthogonal to the workpiece spindle axis for coaxially receiving a deburring tool, and
- a deburring tool having a deburring blade head and a plurality of bar-like blade inserts attachable to the deburring blade head, each of said blade inserts having a shaft for clamping and a free end with at least one edge for chamfering and/or deburring the edges of a bevel gear, wherein the deburring blade head comprises:
- a base holder extending along the deburring spindle axis, said base holder having a connection area at a first end of the base holder for fastening the base holder to the deburring spindle;
- and
- a plurality of blade insert mounting means attached proximate to a second, distal end of the base holder, for respectively clamping the blade insert shafts and holding the blade inserts generally radially oriented to the deburring spindle axis of the deburring spindle.
A method for chamfering and/or deburring edges on the teeth of a bevel gear in a gear-cutting machine having a plurality of numerically controllable axes, said machine comprising a workpiece spindle, which receives the bevel gear coaxially to an axis of the workpiece spindle, a tool spindle, which receives a tool, and a deburring spindle with a deburring spindle axis generally orthogonal to the workpiece spindle axis, said deburring spindle being provided for receiving a deburring blade head with several bar-like blade inserts, wherein the method comprises the following steps:
- inserting and fastening the blade inserts to the deburring blade head so that the blade inserts are generally radially oriented to the deburring spindle axis,
- performing a relative setting and/or pivoting movement between the deburring blade head and the bevel gear, wherein by the setting and/or pivoting movement the deburring blade head is brought into a starting position for chamfering and/or deburring,
- rotating the bevel gear around the workpiece spindle axis,
- rotating the deburring blade head around the deburring spindle axis, and
- with the blade inserts of the deburring blade head, performing chamfering and/or deburring movements in a continuous fashion at pre-determined edges of the bevel gear.
A bevel gear cutting machine for chamfering and/or deburring edges of the teeth of a bevel gear in a continuous process, said machine having a plurality of numerically controllable axes and comprising:
- a workpiece spindle, which receives the bevel gear coaxially of an axis of the workpiece spindle about which the bevel gear is rotated for machining operations thereon;
- a deburring spindle, which receives a deburring tool coaxially of an axis of the deburring spindle about which the deburring tool is rotated for deburring and/or chamfering operations on the bevel gear, said deburring spindle axis being generally orthogonal to the workpiece spindle axis;
- and
- a deburring tool having a deburring blade head and a plurality of blade insert bars attached to the deburring blade head, each of said blade insert bars comprising a shaft with a first end for clamping and a second, distal end with at least one edge for chamfering and/or deburring the edges of a bevel gear, wherein the deburring blade head comprises:
- a base holder extending along the deburring spindle axis and having first and second distal ends, said first end of the base holder being fastened to the deburring spindle;
- and
- a plurality of blade insert mounting assemblies attached proximate to the second end of the base holder, each mounting assembly being configured to clamp the first end of a blade insert shaft, for holding the blade insert generally radially oriented to the deburring spindle axis.
