Hello Friends Welcome to FreeCAD tutorial and in this tutorial we will do the knuckle joint assembly in FreeCAD with the help of A2 Plus Workbench
0:11
As you can see that I have did the knuckle joint assembly with the help of this drawing and you can see that all the parts here are in the exploded view
0:24
I have already modeled this part and I will provide the source file of this assembly in the video descriptions. So you can download it and practice the A2 plus assembly workbench in FreeCAD
0:40
So I will show you from the scratch how I have created this assembly with the help of A2+
0:46
So let's start. You can visit my dedicated playlist on specific topics on my channel like drawing, modeling, micros, workbenches, mechanical design
1:03
I have created separate playlist for different topics so you can visit and watch the videos of your interest
1:15
You can also visit my website MacNexus.com where I write articles on FreeCAD, tutorials on FreeCAD
1:25
I also write articles on mechanical design and I also cover the journal topics on mechanical
1:35
engineering. So you can visit my website link is provided in a video description
1:43
If you like my work and want to support me then you can support me on coffee you can buy me a cup of coffee your small support will help this channel to grow you will find my coffee donation page link my website link in a video descriptions so come back to our tutorial
2:08
so i will discard this file and i will create a new file
2:17
and first i will save my file so here i have saved my file and now i will call one by one part
2:27
in our assembly and we will assemble it so here on a2 plus you will see the first
2:34
option which is add part from an external file click on it and call your first part so our first
2:43
part will be the fork say insert and place it and now here you will see that our part orientation
2:54
is like this in our drawing so we will click on the our inserted part click on the transform
3:05
and here we will rotate it as per our orientations say ok and now we will insert our second part
3:17
which is the IEND click on insert and insert IEND and now we will assemble it
3:33
so first constraint I will give select this face and this face and here you will
3:42
see option of a plane coincidence constraint and accept it now select the surface inside and inside surface of our fork and eye and give the
4:00
axial constraint accept it and now select this face and this face and give the parallel constraint
4:11
to lock the angular movement and now we will insert our pin so click on add part
4:21
on our external file click on the pin Now select the internal surface and give the axial constraint accept it
4:41
Now select the top face and this face of a pin and give plane coincidence constraint
4:53
accept it. And now we will insert the collar, click on add part from external file
5:16
Now select this top face and this face give the coincidence constraint, accept
5:30
Now select the internal face and this face and give the axial constraint
5:37
Now I will click on my collar click on the transform and move it to the down and I will select this face and this face and give the axial constraint accept
6:01
now we will insert our taper pin to lock it click on add part from external files click on the
6:14
taper pin now select the pin surface and color surface view the axial constraint click on
6:27
accept and now click on the taper pin and click on the transform rotate it and
6:43
click on ok again click on the transform move it so this is how the quarter way pin position
7:02
will be so it has the rotational movements to our collar and pin so it doesn't matter
7:12
on the isometric view so you can see that how we have created the assembly in
7:19
