Reciprocal mechanism with 180degree rotation 1

[Tuckabag]

Hi All.
I'm looking for a mechanism that is reciprocal (driven by double acting air piston motor) that can also rotate the driven shaft 180degree from start of stroke to end of stroke and then rotate back to original position on the return stroke of the air motor.
I just cant wrap my head around the right search term to investigate what this mechanism is called and/or how others have done this.
Appreciate any keywords, etc I should be looking at.
Cheers and Merry X-Mas to you all.

It's called a "rotary actuator".

There are a number of ways to turn linear to rotary motion the most common would be a "crank". A "rack and pinion" would also work.

Sorry, I was a few beers and waaay too much Xmas dinner deep when I posted and did an ordinary job of describing what I'm trying to achieve.
I have a shaft attached to a 2 way piston motor that provides reciprocal movement. What I'd also like to achieve is 180deg rotation of the shaft as it strokes. So turn 180deg during a down stroke and then rotate back to the original orientation during the return stroke.
I need the same function as per the attached pic, but they use a rotary mechanism with an eccentric. I only have a recip motor available.
Thanks.

Something like a Yankee drill.

Sorry for the delay in replying.
Thanks @hydtools for the advice, I'll see if I can get a yankee drill type mechanism to achieve what I'm aiming for.
Cheers.

Check out E&E Engineering (

https://eesp.co/).

They have many variations on that theme, including pneumatic and hydraulic cylinders, and add-on devices to add rotation to a standard cylinder.

Thanks @Jboggs.
This is pretty much exactly what I was looking for :

I just need to see if they can offer 180deg rotation.
Cheers!
