The invention discloses a
numerical control gear shaper for
machining a high-precision hardened-tooth-face gear, and belongs to the technical field of
numerical control machine tools. Through the combination of the
ball screw, the linear guide rail and the penetrating transverse shaft, micron-order positioning and stable
linear motion of the tool sliding table in the horizontal direction are achieved, the
machine is compatible with gears of various sizes, the idle
stroke is reduced, and the
machining efficiency and the
machine tool universality are improved; a quick-change clamping jaw, a transverse pull rod, a triangular
cutting edge
impact seat and a movable
chip retaining ring are of an integrated structure, the
cutting edge of the
impact seat is always aligned with the edge of a gear, the movable
chip retaining ring synchronously forms a closed protective cover,
scrap iron is prevented from splashing, edge
machining is faster, more stable and cleaner, and after a large gear bracket-annular tooth groove die hole is replaced, a large-size tooth groove can be formed at a time; and the thin-wall disc gear can be accurately positioned by the central positioning column, so that deformation is prevented. The whole machine has multiple purposes, and the universality and the flexibility are greatly improved.
