ボール盤の早戻し機構。 It consists of a magnet with a magnetic coil wound around an iron core, a stand attached to the top of the magnet, and an electric drill attached to the stand so that it can move up and down, and the stand has a feed motor, a reduction unit, and a handle. It consists of a clutch part that switches between automatic feed and manual feed of the electric drill by axial movement of the shaft, a high-speed specific reduction gear is used as a part of the reduction part, and a gear is attached to the input side of the high-speed specific reduction gear, In an automatic magnetic drilling machine equipped with an automatic feed mechanism in which one of the clutches is attached to the output side and the handle shaft passes through and supports the gear and the clutch, an electromagnetic clutch is used for the clutch, and the clutch is connected to the clutch during feeding. A quick return mechanism for an automatic magnetic drilling machine configured to transmit power by energizing an electromagnetic clutch, and to perform a quick return by directly rotating a handle shaft from an input gear without being energized during return.
