Document Type and Number:
WIPO Patent Application WO/2021/098364
Kind Code:
A1
Abstract:
A numerically controlled machine tool for spiral bevel gear machining, comprising a machine tool body (100), a column (200), a cutter spindle box (300), a workpiece spindle box (400), and a rotary table (500). The rotary table is mounted on the machine tool body and can move linearly along the X-axis direction; the workpiece spindle box is mounted on the rotary table and can rotate along with the rotary table around the Y-axis direction; a groove is provided on the machine tool body along the Z-axis direction, and the column has the lower end mounted on the groove and can move linearly along the Z-axis direction; the workpiece spindle box is mounted on the column and can move linearly along the Y-axis direction. By mounting the column in the groove of the machine tool body, the height of gravitational center of the column is reduced, the stability of the entire machine tool is improved, and moreover, the column has better adjustment performance.
