Claims (8)

An internal tooth shaving device that meshes a shaving cutter and an internal gear held by a work chuck with an intersecting angle, and finishes the tooth surface of the internal gear while rotating at least one of the shaving cutter and the work chuck. There,
Wherein A workpiece chuck and shaving cutter, the workpiece chuck and the upper, are relatively movable in the horizontal direction,
The work chuck is supported so as to be able to approach and separate from the shaving cutter, and the shaving cutter is supported so as to be swingable about a horizontal axis so as to give an intersection angle with the rotation axis of the internal gear. ,
The work chuck is driven by gripping the outer peripheral surface of the internal gear so that the shaving cutter generated during processing by the shaving cutter can fall downward from the internal gear with the axis of rotation of the internal gear directed vertically. An internal tooth shaving device characterized by comprising: The work chuck is configured to be supported so as to be movable laterally and to hold the rotation axis of the internal gear in the vertical direction.
A workpiece transfer unit for exchanging workpieces at the side position of the workpiece chuck;
The work transport unit is configured to support the internal gear with its rotation axis in the vertical direction so that the work chuck can grip the internal gear on the work transport unit from above. 2. The internal tooth shaving device according to claim 1, wherein The work replacement position located between the front Symbol workpiece chuck and the shaving cutter, carried the internal gear, further comprising a workpiece transfer unit for unloading the internal gear from the work replacement position,
The work transport unit is configured to support the internal gear with its rotation axis in the vertical direction so that the work chuck can grip the internal gear on the work transport unit from above. 2. The internal tooth shaving device according to claim 1, wherein   Each of the shaving cutter and the work transport unit has an indexing element of the internal gear so as to enable phase matching between the shaving cutter and the internal gear held by the work chuck. Item 4. The internal tooth shaving device according to Item 2 or 3. Before Symbol work transport unit,
A workpiece replacement position having a first swing axis parallel to the rotation axis of the workpiece chuck and positioned on the vertical movement path of the workpiece chuck and a workpiece loading position spaced laterally from the workpiece replacement position. Between the swinging work loading arm,
A workpiece unloading arm having a second swing axis parallel to the rotation axis of the workpiece chuck and swinging between the workpiece replacement position and a workpiece unloading position spaced laterally from the workpiece replacement position; The internal tooth shaving device according to claim 3. 2. The internal tooth shaving device according to claim 1, wherein the shaving cutter is supported in a horizontally movable manner so as to cut the internal gear at a position where the shaving cutter enters the internal gear. The main shaft for rotationally driving the work chuck extends upward from the work chuck, and a coolant supply hole for supplying a coolant to an internal gear to be processed is formed in the main shaft. The internal tooth shaving device according to 1 or 6 .   The internal-tooth shaving apparatus according to claim 1, wherein the shaving cutter is supported so as to be able to rotate together with the internal gear that is rotationally driven.
