Claims

[Scope of utility model registration request]

In a machine tool, an automatic and manual feed switching device that connects and connects a pinion shaft included in a power transmission line for moving the main shaft sleeve on which the main shaft is supported, and a pinion gear rotatably provided on the shaft. The pinion shaft is provided with a handle body adjacent to the pinion gear and the handle body, spline teeth are formed at opposing ends of the pinion gear and the handle body, and a slide sleeve is formed on the spline teeth of the handle body. is fitted to the pinion gear in a spline-sliding manner, and positioning means is provided between the slide sleeve and the handle body to hold the sleeve in a position on the handle body and in a position where the sleeve is connected to the pinion gear. An automatic and manual feed switching device for a main spindle in a machine tool, characterized by the following.
