Claims

[Scope of Claim for Utility Model Registration] (1) A lathe main shaft that is removably installed near the rear end of the main shaft of a lathe having a rotating tool, and that allows the lathe main shaft to perform angular position indexing and controlled rotational feeding. The control device includes a main shaft portion including a control driven gear provided at the rear end of the lathe main shaft, and a control drive gear that is supported in parallel with the lathe main shaft and is controlled and driven by a servo motor for output. a control shaft portion having a fitted control shaft; and a controlled driven gear disposed on the main shaft portion so as to be rotatable about the control shaft between the main shaft portion and the control shaft portion. and an intermediate shaft portion including an intermediate gear that engages with the control drive gear in a freely engageable and disengageable manner. (2) The control device for a lathe spindle according to claim 1, wherein the ratio of the number of teeth of the control drive gear, the intermediate gear, and the control driven gear is set to 1:1:1. . (3) Practical use characterized in that when the intermediate gear is in mesh with the controlled driven gear, the intermediate shaft is located at a right-angled vertex of a right-angled isosceles triangle between the control shaft and the main shaft. A control device for a lathe main shaft according to claim 1 of the patent registration claim.
