Propeller shaft sprue cutting device

Abstract

The utility model relates to the technical field of propeller production, in particular to a propeller shaft sprue cutting device. Comprising a base, an annular diamond rope is arranged above the base, and a vertical pipe is vertically fixed to the middle of the upper side wall of the base. According to the device, the worm is driven to enable the worm gear to drive the winding wheel to rotate, the rotating winding wheel winds the pull rope, the pull rope is guided by the reversing wheel to lift the extending plate upwards, the extending plate drives the sliding sleeve to move in the axis direction of the vertical pipe, and therefore the height of a sliding whole including the extending plate and the height of the diamond rope can be increased; the worm is reversely rotated to enable the winding wheel to unwind the pull rope, the sliding whole and the diamond rope can move downwards under the action of gravity, the purpose of lowering the height of the sliding whole and the height of the diamond rope is achieved, the height of the diamond rope cutting part is matched with the to-be-cut position of the propeller shaft by linearly adjusting the height of the diamond rope, and therefore the propeller shaft is cut. Therefore, the device can be used for cutting sprue metal columns with different heights on a propeller shaft.
