Abstract
The invention discloses an inner bore tapping tool for a small-bore thread steel sleeve with an external thread and a method of the inner bore tapping tool. The tool and the method solve the problem that concentricity cannot be guaranteed when an internal thread of a screw sleeve with the high-precision concentricity requirement is machined by means of an existing lathe. The tool is characterized in that a supporting cylinder outer circle face (15) of a supporting cylinder (3) is clamped into a machine tool three-jaw chuck (2); a cylindrical connecting table (10) is fixedly arranged on the top face of the supporting cylinder, an external cylindrical connecting table thread (6) is arranged on the outer side wall of the cylindrical connecting table (10), and a connecting cylinder (4) is in screw joint with the external cylindrical connecting table thread (6) arranged on the outer side wall of the cylindrical connecting table (10) through an internal connecting cylinder thread (5); and an external screw sleeve thread (8) is arranged on the outer side wall of the steel screw sleeve (7), the steel screw sleeve with the external thread is connected into a steel screw sleeve inner bore tapping bore in a screw joint manner, and a tapping cutter (11) is arranged over the steel screw sleeve (7). By the adoption of the inner bore tapping tool, the high-precision concentricity machining requirement of the screw sleeve is met.
