@@chrisjbo1505 The linkage here is a four -bar linkage. That means also there are four pivot points in one plane. One link is fixed, but the other three move. Imagine pushing down on the cylinder body. Nothing will prevent the cylinder from pivoting around its pivot pin, so you cannot maintain a downward clamping force on a workpiece. If you clamped the cylinder to the base of the vise so it doesn't pivot, then as the rod extends, a force will be exerted on the end of it, which is perpendicular to it. This is damaging to cylinders. Cylinders must only exert straight-line force, along a line between its two pins.
@@chrisjbo1505 The red part is meant to push down with much force to hold an unknown object in place. The force must come from the shaft and piston. The shaft is best used to push or pull in a straight line with itself, not to apply a sideways force as it does with the clamp.
@@chrisjbo1505 it's okay if the clamp pivots, but the leverage that makes the clamp tight should not make the piston push sideways. Pistons push or pull. The way to make this good for the piston is to move the piston 90 degrees so that it is putting force in the same direction as the clamping force.
NG. The cylinder will pivot around its mounting point, and if you restrain it further, you will ruin the cylinder from the lateral force.
是的
I'm just learning about this type of thing, could you please explain further why that would happen?

@@markm8188 Ok i think I get it. Thank you!!!
Putting a lot of pressure on the ram shaft.
It would be easy to add over-centre to this so workpiece movement doesn't reverse drive the linear actuator.
Interesting mechanism, but a lot of side load on the shaft. Would need an intermediate mechanism to prevent bending.
Could you explain would this means please? I'm new to these type of things.

@@machinemaker2248 oh ok that makes sense. So the fact that the clamp thing pivots is a bad idea correct?

How can I learn this
What softwares do you use? Great works.
can you please give link for the SolidWorks mechanism parts?
Could you share me the solidworks file? Please
Bu mekanizmaları nerde bulurum
can this motion be possible in solidworks motion study ?
