In/out motion by twist 2

The pink rod has prismatic joint with blue body.
Twist the knurled grip clockwise to get out motion of the rod.
Twist the knurled grip back to get in motion of the rod.
The red pin fixed to orange core slides in the slot of green barrel cam.
The green spring and suitable shape of the cam slot keep the rod stable at its in/out positions.
The disadvantage of this mechanism: the in/out stroke length can not be large because the cam pressure angle must be kept small enough for easy motion.
The mechanism can be applied to twist pens.

Excellent. This canal is a huge knowledge bank.

[@leo-the-truck7672]

WOW WOW Thang, it did not take you long to have this done as I requested these type of mechanism to be created and you just had it done in less time, I know there is alot work to it but you made it looks easy and simple, Thanks so much, you ROCK

[@antonioclaudiogimenes3703]

Many thanks for the files in Autodesk Inventor. I always wait for them. Thank you very much

Good job.
Can you help to make mechanism for wheat seed singulation ?

[@thang010146]

Could you show me pictures or videos related to the mechanism?

Great.

What's the application/software to make picture animation like that?

Once torque is no longer applied, does the mechanism reset itself, spring back up or is it just from the animation ?

[@thang010146]

Please read the video description.

@@thang010146 I see now, thank you.
I am looking for some design ideas that consume torque, sort of rotational damper. I see some ideas that turn rotation into linear movement and compress a spring but I need something that is reversible once torque is no longer being applied. Do you have something similar maybe in your models? Regards.

[@thang010146]

Pay your attention to the straight slot on the green part.
If it is shorter (no circular concave portion at the end of the helical slot), the pink rod will get back to its initial position once torque is no longer being applied.

@@thang010146 understood, thanks for the hint !

thanks!
how to make a pen tattoo mecanism please!

I will study it and make its animations if possible.
