About This Product
The Whitworth quick return mechanism is used in machine tools such as shapers to give a slow cutting stroke and a faster return stroke. A rotating crank drives a slotted link, and the tool, attached to a guided slider, moves back and forth. Because the distance OP is fixed, the ratio of cutting to return stroke is fixed, while setting the crank pin to a different radius changes the stroke. On the board, students move the links by hand and use a pencil in the hollow rivets to draw the loci of the joints on paper.
Frequently Asked Questions
Q1. What does the Whitworth Quick Return model show?
It shows a quick return mechanism in which the crank drives a slotted link and the tool is attached to a guided slider. The ratio of cutting to return stroke is fixed because the distance OP is fixed.
Q2. Can the loci of the joints be recorded?
Yes. The hollow rivets accept a pencil, so the loci of the joints can be transferred to a sheet of paper clipped to the board.
Q3. How can the stroke be varied?
The crank has a pin C that can be set at a chosen radius to drive the slotted link, which varies the stroke.
