Scotch Yoke Mechanism
The Scotch yoke is also known as slotted page link mechanism. The slotted page link mechanism is used for converting the linear motion of a slider into rotational motion or vice-versa. This mechanism is generally found on shaping machines where single point cutting tool is mounted on the front of the slider or ram, in a hinged tool post. The tool cuts on the slow forward stroke and lifts over the workpiece on the quick return stroke. The slotted page link rocks from side to side, driven by the sliding block on the bull wheel.
