[Music] when working with in designing jigs or fixtures with locating pins proper alignment is crucial to ensuring smooth operation and repeatable results this episode will address a few of the most common solutions to alignment concerns for locating pins if you’re unfamiliar with the basics of locating pins and workholding concepts check out the previous episodes in this series to get up to speed one of the biggest issues a new fixture designer encounters is binding of a part where the way it is placed or removed from a pair of locating pins causes it to become stuck and out of alignment this can lead to production line slowdowns or in worse cases reject parts due to improperly assembled or machined components one method to counteract this issue is designing the jig using locating pins with a lead-in on the head this can be in the form of an angled or tapered head sphere or bullet nose and helps to Center and ease the part onto the pin take care when incorporating ledin though as too much lead can result in a taller pin and create added difficulty in loading or unloading the workpiece the other main way to avoid binding of a workpiece with the pair of locating pins is to use a dissimilar pair of pins specifically a 2-way and a 4-way pin together this is most commonly achieved through the use of a round pin and a diamond pin which allows some radial play as a degree of freedom helping to alleviate any lateral binding of the two pins with the workpiece with a better understanding of how to use pins with the leaden and dissimilar pin pairs you should be well on your way to minimizing workpiece binding if you need a refresher on two-way and four-way locating pins check out episode 2 of our locating pins series and if you’re interested in how to select materials and coatings for locating pins tune in to our upcoming episode on material selection if you like this video be sure to click the thumbs up below to stay up to date on all our newest videos subscribe to our Channel and don’t forget to follow us on social media to see our latest content you
