Mechanism Pin Connection

Hola -

 

I have a pin that is depressed by another part and need to know how to establish the connection. The problem is that I need to somehow have something similar to a Cam Connection's "Liftoff" function because the other part isn't always in contact with the end of the pin.....

 

Any suggestions?

 

TIA

Re: Mechanism Pin Connection

Use 3D contact and some simple construction surfaces that are supported by 3D contact, like a sphere and a plane, or even use multiple spheres to make contact zones on your part.  The pin can be on a cylinder joint or whatever allows/constrains the motion desired including spring biasing etc.  It still may be possible to use a CAM, but if the end of the pin is flat or a spherical dome you would need to change it to a convex straightly extruded surface that approximates the original surface.  A CAM can sometimes be used in situations that don't look so much like a CAM, even 90 with degree oriented shafts, rather than parallel.  A CAM is much less cost computationally than 3d contact in my experience.

 

If you are still working on this and if possible add a screenshot so we have some idea what you are up against.
