Assembly joints

[Anonymous]

Hello,

I am completely new to assembly module if Fusion 360. The screenshot below demonstrates my assembly setup. The impeller can rotate around his axis, but I would like to rotate it to a certain position and lock it. I have attached my file as well if it is going to be helpful.

Select Turbine wheel, (body1) in the browser

Right click> Move / Copy

Set Move Triad pivot position and confirm,  to centre of the wheel.

Rotate 5 degrees to the left at the top.  Counter Clockwise.

Select the Joint and Lock it.

Might help...

Why 5 deg?   I do not know if it is 5 deg.

Actually, it's 5.029682 degrees. I created an Offset Plane out in front, started a new sketch on it, projected in the desired plane, the face of the fin to be rotated, and the center point about which the rotation will take place. Then I drew a couple of lines out from the center point to the edge of the fin and the intersection of the impeller wheel and the desired plane, and dimensioned those two lines.

You just need to set the Rest limit of the Revolve Joint to that value. And then manually rotate the wheel a bit to get that Rest limit to take effect and jump the fin into the right position.

Ooops. I'm sorry, I had it wrong. I had my second line through the wrong point. It's actually 5.009850946 degrees.

Understand, you did it by getting the angle value out of the sketch.  I was hoping there is simply way just like constraints in the sketch by selecting the line or point on one feature and plane or line on another, then to apply "coincident" constraint.    Is it the only way?

Thank you for your reply

Or, maybe there is a way to link the value of the angle from the sketch with the rotation of the joint?

Components are free to move until jointed.

I used a sketch, was 5.000 degrees in the file I worked in.

the reason I mentioned rotating the body was to keep the Joint system settings intact.

Rotate the body to the indexing position, leaves the Component Origin alone, as it was not aligned to any feature, would not break the model.

Transfering an angle at the time of making the joint, in this case need to know that angle before hand.  Does the model need a Revolute Joint, when you asked to lock it place, a Rigid Joint would do it - the way you are thinking.
