Found this in a local semi truck service shop that closed down.

It has a Milwaukee holehawg drill motor.
It has a drill bit guide that's for a 7/16 drill bit, it has a 12" and a 18" bit with it.
This is threaded for a 2 1/2" pipe looks like a finer thread to me.

Any ideas?
I can get more pics if anyone what's them
Feel free to cross post this to other sites, I'd like to know what its used for before I strip it apart for the motor

Before you disassemble the device, what else was with it?
It could be the drive for a reamer or boring bar or it could have been used as a frame drill.
From what I see in the picture I'm leaning toward frame drill at the moment.

2 drill bits was the only other things in the shipping case I found it in, there was a cylinder honing brush in the room where I found this, I'll check and see if it's a 7/16 shaft on the brush.

On the bottom of the stand, is a big nut. Looks like a big truck axle nut for a full floater. I wonder if this could be a rig someone dreamed up to drill down into a broken off axle shaft, so it could be threaded and pulled out?

10 years ago I would have been looking to grab it for a power unit for line boring things like boom and bucket pins. Thankfully I no longer become involved beyond saying You can do that when asked about such jobs.
The assembly bears resemblance to the power end of a truing unit for rebuilt in place spindles on full floating truck axles. It also bears resemblance to a number of other power units.
I do not see the large nut referenced as a holding system for the power unit, not enough purchase for the power the drill motor produces. More likely for line reaming pins or shafts. Aluminum makes sense for weight on a portable unit. The bushing at the base would easily accommodate a boring bar. Aluminum base probably floated in a shoe assembly that was attached to the item being bored.
Also be handy as hell as a column or beam drill, strap shoe in place, drop power unit into shoe and secure.
Finding in a truck garage might also indicate use reaming walking beam bushings.
