Threading arm with screwdriver
Good morning.
I wanted to introduce my next design which is a threading arm.
The base of the machine is a 400 kg magnetic lifter ordered from a well-known Chinese portal for the sum of 330 PLN.
.
I bolted a flat bar to the top of the magnet with a welded 30 mm shaft. I then screwed linear bearings to the 80x80 profile on both sides and put the whole thing on the shaft.
.
The next components of the arm are two 30x30 profiles which are supported by two 120 N actuators.
.
The last element of the arm is a screwdriver handle made of 15 mm sheet metal.
.
I also decided to make a threading head for the shafts.
The largest threader I had was 14mm and it went without a problem, but the thread is not very deep despite using a 12mm thread drill.
.
You can see the entire stage from the machine build and testing in the video below.
I encourage questions and comments.

Nice video of the build. I have a feeling that this arm would even manage this screwdriver together with the operator. [Read more]
I generally like the design, only these linear bearings, as the name suggests are not suitable for the kind of work you are doing. Rotation instead of feed along the shaft. I've used smaller ones and they... [Read more]
Beautiful construction. And you can see the super "balanced" forces needed to position the "head" in the right place. . With his wife and children on his lap. :D Robust construction. . And this... [Read more]
Elegant design. In case the unit has to work hard, you can possibly remove the bearings from the housings and insert 30x45 bushings there as pan. If you don't have time to do the work, you can buy some... [Read more]
I don't know what you're getting at with this corom... To quote my own statement from about a year ago. I know two meanings of the word and neither has anything to do with drills. 1. koromyslo - a carrier,... [Read more]
. I see a similarity here - the counterweight I used to fully control the pressure of the drill. You can't see it in the photo, but there is a double-sided lever (double-armed), the weight of the linear... [Read more]
Years ago I got a "column tapping machine" from a friend, unfortunately it later went to scrap, but in general I remember the construction, the head (something like an ordinary chuck for a column drill)... [Read more]
I think such devices are still produced as threading heads, as well as for fine drilling. Maybe I can find cross-section drawings of the construction. There's a satellite gearbox and something like a... [Read more]
For threading blind holes and deep holes I make my apologies with a screwdriver She 'buzzes' a bit but has an adjustable clutch so I attach her to the Koromysl crossbeam. I don't have to listen to music... [Read more]
Congratulations, you are in second place in DIY constructions: https://www.elektroda.pl/rtvforum/ranking.php And probably immediately in first place. Respect. If you allow me, I will send you a small... [Read more]
