Joint cone to cone

Hi Guys,

  I have a problem trying to make an assembly of 2 conical parts - male and female.

The ends of the truncated cones are not coincident so there is no 'point to point' assembly possible, but i need to make the joint.

  For example, male and female morse taper where the cone 'ends' and the center point of the cone do not line up.

Seems like we could do with a surface to surface type joint, but there is not this functionality.

Any advice is useful, thanks in advance

put a sketch point on the akis of the mail cone where it is the same diameter as the opening of the female cone, and apply the joint to that. example attached.

It's a bit hard to tell from just the images - can you share the model?  It looks like you can probably pick the circular face on each truncated cone, and that should produce a snap point at the center of that circular face, which can be joined to the center of the other truncated cone's circular face.

 

If that is not the geometry I think I am seeing in the image, then, again, seeing the model will help.  Sometimes you have to use Joint Origins in more complex geometry cases.

If you Split face at the contact diameter, you can then select arc (to find center of arc).

 

The advantage to this technique is that it does not require any math calculations (geometric solution) and updates with changes to model.

Pythagorean theorem will allow you to get a parametric solution.

If you created the cones with the Revolve tools, then presumably you have sketch(es) containing axis center line and interior/exterior walls.

 

Two Slider Joints will solve the fitment. One Slider Joint between the axes of the cones, and one Slider Joint between the interior of the female cone and the exterior of the male cone.

 

Please note that I spend some time confusing myself, then undoing those steps, and then finally doing it right.
