Abstract

The invention discloses a machine tool structure for machining internal herringbone teeth, and relates to the technical field of gear machining. The internal tooth machining device comprises a machine tool feeding mechanism, an internal tooth machining mechanism and a workbench, wherein the workbench is arranged on one side of the machine tool feeding mechanism. The internal tooth machining mechanism is matched with the X-axis feeding assembly, the Y-axis feeding assembly and the Z-axis feeding assembly in the machine tool feeding mechanism to be in linkage with the C-axis rotating assembly in the workbench, overall forming machining of the double-spiral tooth face of the large-specification clearance-groove-free internal tooth herringbone tooth gear ring can be achieved, and the internal tooth herringbone tooth machining and assembling procedures are reduced; a workpiece is horizontally placed above the workbench and is clamped and fixed once through a clamp, the workpiece clamping efficiency is improved, the structure has high rigidity, high-precision machining of internal tooth herringbone tooth workpieces of various specifications can be achieved by being matched with machine tool feeding mechanisms of different specifications and finger-shaped milling cutters of different specifications, the application range is wide, and the machining precision is high. And the blank of integrally processing the inner tooth herringbone tooth structure by the finger-shaped milling cutter is filled.
