Pin-slot joint Lever

Anonymous
Not applicable

I'm trying to make a custom lever latch assembly. I'm still having a hard time figuring out how to assemble in Fusion. I'm pretty solid in the drawing but I'm used to constraints from SolidWorks. I've gotten this far. I need that slot to confine that pin on the latch so I can see how much motion I'll need to open the latch. Right now, it kinda works, as in, it moves correctly for a little then won't move until one wall reaches the center of the pin. 

 

I'll upload a screencast if I need to. 

 

Thanks!

Looking at you assembly the very first thing I'd like to say is to forget using contact sets in conjunction with joints. It almost always creates problems.

 

The second thing is that you'll have to re-do this if you really want to learn how to work with components most effectively.

You followed this workflow, which is suboptimal for many designs:

Sketch->Body->Component

 

Why you should to:

Component(Activated!) ->Sketch->Body

 

That is called:

 

Fusion 360 R.U.L.E #1 : Before doing anything, create a component and make sure it's activated.

 

All objects created after activating the component such as sketches, bodies, construction geometry, joint origins, etc.  are created in that component.

This has several advantages:

  1. On activation the timeline is filtered to show only those items in the timeline that pertain to that component. That will make the quickly growing timeline much easier to work with.
  2. If a component is exported to the data panel with "save as" this will also export the complete parametric design history.
  3. Drawings can only be created from components
  4. The joints in the "Assemble menu only work with components.

When another component needs to be edited for example to add geometry, it should be activated before doing so.

 

I'l see where I can get with the joints.

The second error you made and which many folks coming from SW stepping into is that you highlighted an object in the viewport with a single left-click and then used the move command.

Unfortunately that does not do what you might think it is.

What you want to do is move the component. What you are doing is moving the body winthin the component away from it's origin in the component.

 

To highlight a component in the viewport you need to double-left-click on it. Then you can move it.

In ended up actually doing this with a contact set beaches A. I felt lazy, and B.because we currently don't have a CAM joint that would make this easy.

It's in the idea station, so please vote for it. Here is another similar idea and another one.

 

Here's a screencast :

Thank you. I was definitely backwards! I'm gonna go work with it and try to figure it out! So to be clear, from a new design, I have to create a component then sketches inside of the component and then make the body, etc.  ?? What about importing models? I like to keep components of assemblies separate. Is this a good way or a bad way to go about this?

Yes, for your current design that is a better workflow wand will create a better structure. There are cases when you would not follow the rule but for a design where you design discrete pieces from scratch using a sketch this works best.

That can be done by inserting them you your current design from the data panel.

For larger designs in collaborative environments that may make sense. For your design at this point it would not. Fusion 360's paradigm at the moment does nt ope the flexibilities you are used to in Solid Works.

You can perfectly fine organize your design in Components, Assemblies in a single design as Fusion 360 does not have separate file formats for that.

Hi
I am new in Fusion 360
i am used Solidworks
Could you please explain, what kind of joint have you used in this case?
if it is slot, actually what you set in slide way?

I tried to make same connection but....

i see the problem is in slide direction

Hello 🙂

 

I know this is late relative to when this message was first posted.  

I've been going over all the solutions as a training exercise and I keep on seeing you helping people Peter.

Thank you

 

The attitude in this forum is so excellent.
