Assembly question, angled flange onto a collar

Assembly question, angled flange onto a collar

Assembly question, angled flange onto a collar

(OP)
I am mounting a flange onto a body and am having some issues.  I can set the distance from the flange to the end of the unit (0.062") but I can't get it concentric with the angled end.  I have made a SLPRT from the current ASSY so people know what I am talking about.  What mates should I be concentrating on here.

RE: Assembly question, angled flange onto a collar

I didn't open your file (I am using 2006 so I assumed I wouldn't be able to open it... you may consider posting a jpg).

Anyway, there are other methods to mating things concentric other than mating faces concentric.  You can create an axis in each part and then mate the axes coincident.  You can use the base planes or create new ones and mate those coincident or parallel.  Many of these mating methods are more robust than selecting faces and mating them.

That being said, you may want to try to do the concentric mate before the distance mate (or suppress the distance mate).  you may find that your face that you are using in the distance mate is not perpendicular to your axis of concentricity.  If that is the case, do your distance mate with an edge or a point.

RE: Assembly question, angled flange onto a collar

You can't get the flange concentric because the the flange is circular while the edge you want to mate it concentric to is elliptical.  You won't be able to hold a distance of .062" all around the pipe because the the two parts are not both cylindrical.  The best you can do is to made the angled plane parallel/distance to the flange and mate a center sketch point on the flange coincident to the pipe axis.  You'll also need another parallel mate to keep the flange from rotating.

RE: Assembly question, angled flange onto a collar

Use coincident to either a temporary axis or create an axis through both parts.  Should be fairly simple since both are cylindrical.  Omit the distance mate and be sure that they can slide freely then lock down the other 2 degrees of freedom.

If the axis trick doesn't work, how are the 2 cylindrical faces being created?  One might have a taper causing an issue.

RE: Assembly question, angled flange onto a collar

The bore of the flange can be mated Concentric to the pipe O/D ... or the face of the flange can be mated Coincident (or Distanced) from the angled face of the pipe ... but not both. That means that the angle of the bore of the flange does not match the angle of the pipe end face.

I re-created the parts with matching angles and was able to add all the mates required.
