Now that we have a Diamond Pin that is only touching the part on the top and the bottom of the pin, we need to make the contact points of the pin remain in the same up and down orientation.

To say it differently, we have to make sure the diamond pin doesn’t rotate.  We can do this with a flat cut on the pin and a shoulder screw mounted next to the cut.  Let’s take a look at the video…

 

Thanks for joining me as we learn together. I hope you are having as much fun learning as I am!

Next week we will talk about how this sub assembly is shimmed and mounted.

Using a Pin for Orienting vs Locating

We are continuing our discussion of the use of a Straight Line Action Clamp in a weld fixture.

The purpose of the clamp in our sample fixture is to move a locating pin into a hole in the product part to locate.  Then, after the product is welded, the Straight Line Action Clamp can retract the pin, so that the product can be removed from the weld fixture.

In this weeks blog video, a round locating pin is replaced by a diamond pin in our sample fixture. using a straight line action clamp. Instead of locating the customer’s product in the weld fixture, we have changed the purpose of the pin. It is now only orienting one product part with respect to the other product parts to which it will be welded.

Next time we will be talking more about this diamond pin and the bushing block it is moving in.
