Title: TOOLING FOR MACHINING TEETH OF A GEAR HAVING A NON-CIRCULAR CENTER HOLE WHICH IS EASY TO FIX A WORKPIECE Abstract A tooling for machining teeth of a gear having a non-circular center hole which is easy to fix a workpiece, comprising a machine tool spindle one-piece mandrel arranged on a machine tool and a rear top cover fitted with the machine tool spindle one-piece mandrel for fixing a gear having a non-circular center hole; one end of the machine tool spindle one-piece mandrel is fixed on the machine tool, while a left groove which can be matched with a step of the gear having a non-circular center hole is formed at the other end of the machine tool spindle one-piece mandrel; and, a right groove which can be matched with the step of the gear having a non-circular center hole is formed at one end of the rear top cover, while an external conical groove matched with a tip of the machine tool is provided at the other end of the rear top cover; the right groove of the rear top cover comprises a first right groove section, a second right groove section and a third right groove section; the aperture of the first right groove section is greater than that of the second right groove section, and the aperture of the second right groove section is greater than that of the third right groove section; and, the step of the gear having a non-circular center hole successively passes through the first right groove section and the second right groove section and then extends into the third left groove section. 1 4:3 424 1 <3 2 122, |
