磁気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. It consists of a clutch part that switches between automatic feed and manual feed of the electric drill by moving in the axial direction, and a high-speed ratio reduction device is used as a part of the reduction part, and a gear is attached to the input side of the high-speed ratio reduction device and the above-mentioned gear is attached to the output side. In an automatic magnetic drilling machine equipped with an automatic feed mechanism in which one side of the clutch is attached and the handle shaft passes through and supports the gear and the clutch, the high-speed specific reduction device is installed so that the rotational directions of the input side and the output side are the same. A one-way clutch is installed on the inner diameter of the gear on the input side so that the handle shaft rotates idly relative to the gear during feeding, and locks the handle shaft and rotates simultaneously when returning. Therefore, a solenoid coil and a plunger are arranged so that one of the components of the high-speed specific reduction gear is fixed during feeding and freely rotatable during return, and power is transmitted through the high-speed specific reduction gear during feeding, and when returning A quick return mechanism for an automatic magnetic drilling machine configured to allow quick return by rotating the handle shaft directly from the input gear.
