Typically, locating pins are used for controlled, fine tolerance positioning of a work piece. For example, a pallet that is moved along one axis, where the drive mechanism is not accurate and stable enough to place it in a position sufficiently accurate to execute a particular process, the use of locating pins may be the best solution.
Usually two locating pins are enough to properly locate the work piece on one plane.
There are dozens of styles of locating pins that can be utilized in a design. We will explain the structure and show an example of how each style can be applied.
One of the most common pins is a stepped pin with either small or large head.
