Overview:
There are several different types of adapters, brackets, fixtures and mounts that are needed to accessorize a materials testing system. Identifying which adapter you need is easy and Universal Grip can help fit grips onto any testing machine.
This page attempts to cover as many of the standard adapters as possible. There are many potential combinations of sex, sizes, and shapes, however UGC has standardized on a male eye end design which attaches to the female coupling on the grip using a clevis pin and jam nuts. Often times, just one set of adapters can unlock your machine to our complete product line.
Universal Grip has the capacity to design and machine custom adapters and fixturing to meet your exact needs.
How they Work:
The standard grip attachment uses a clevis pin style adapter mechanism. The end of the grip fixture is typically female, with most having a diameter of 5/8" or 1.25" (Df). The female end receives the male eye end and the whole thing is then secured with a locking pin. There is still a bit of play in the locking pin so jam nuts are used to tighten everything and lock it into place. The jam nuts are tightened with a special wrench called a spanner wrench.
Key Measurements:
There are 3 key measurements that are necessary for specifying adapters:
1. The outside diameter of the eye end. (If it is female, then ID)
2. The diameter of the pin hole, or the locking pin.
3. The distance from the bottom of the adapter to the center of the pin hole.
