Join Leon van den Heever for an in-depth discussion in this video Piston and camshaft assembly, part of Modeling a Motorcycle Engine with SOLIDWORKS.
- Next, we want to create a sub-assembly of our piston, cam-shaft, and the valve components. For that, let's start a new assembly and we'll add the Piston Final Part as a fixed component. Let's save this assembly as "Piston and Cam-shaft Assembly," again within the Assembly Components Folder. And then let's insert components and add the cam assembly from the Assembly Components Folder.
Now click anywhere in the Graphics View to place the sub-assembly. To get the sub-assembly mated, since this is already an assembly. We will want to make it flexible, so we have individual control over the cam-assembly's components. Now to do this, simply select the cam-assembly in the Feature Manager and then from the Context toolbar select the "Make Sub-Assembly Flexible" icon. Notice the changed icon, to indicate this flexible state to us. And you will notice we can now independently move each component group within the assembly.
Which is exactly what we need. Again, using the "Control-Select" method to mate, let's mate these two faces, and make them concentric. And then we'll go ahead and do the same for the valve beside it. And then also for the opposite set of valves. Exactly the same as what we've just done.
For presentation purposes, we will also add a distance mate between the bottom of the valves and the top of the piston, and we'll set this to thirty millimeters. Now with that done, save the assembly, close it, and I'll see you in the next video.
