Trying to get my head around this mechanism but hoping /DIY/

What ratio of down to left motion do you want?

First thought. But it lacks an Arduino so improvements needed.

>>1093586
this method is thought provoking for my project.... but i am hoping for more of a clamping mechanism so that the bottom becomes a clamp

Second idea. Still no Arduino. Hmm.

>>1093587
i dont really know how to calculate the ratio but the movement isnt critically important... but it needs to clamp tight

Nailed it.

gears

whatever ratio you want

>>1093597
funny... but the flaw in this sketch is that the linear actuator would push away from the grip and not enforce a clamping mechanism

just use a rod and brackets, so long as the second lever is on a track.

How did I do anon?

how much clamping force do you need, and how much force to the leaver do you want to apply?

my idea is almost like this >>1093586

instead of using a cable and pulley, use a rack in pinion, the gear replaces the pulley. to increase the movement you would need a larger gear, but clamping force would suffer the larger you go?

another idea in my picture, instead of gearing just connect the leaver to the slide as pictured, downward force would equate to lateral movement

lol perhaps i should have read the whole thread before putting my 2 cents in >>1093773

>>1093586
This would not work; the string would not be pulled when the lever is moved

>>1093738
This would work

These will be your cheapest, easiest options. Similar concept behind vice grips. Just don't forget a hinge at the bottom of the top lever.

This might work better. If the moving end of the added link can drop below the line through the fixed pivot and sliding bar pivot, the system will 'latch' much like the mechanism of locking pliers.

Wait a minute...

Are you trying to meme this, again?

>>1094971
Its the guy in the other thread who said that design is garbage, and that he will design a better mechanism for it

>>1094982
I can't think of a radically different design that will do better without losing simplicity or durability

It is basically a parallel jaw on a rail, this cannot change, with a turning element that pushes it, this cannot change also

Maybe some optimization of the geometries but this is already probably the simplest mechanism it can be
