multiple screwdriver for couple controlled pickers?

[reggio]

hi guys, a long time ago, visiting a customer I seem to have seen a special pneumatic screwdriver that allowed to squeeze in a blow only a series of screws arranged circularly ... we in the workshop we have thick need to tighten calettators & co (possibly to controlled couple), for this reason I tried to find that tool to assess its characteristics and purchase but I found nothing ...
have you ever seen/used a similar tool?could also go well even without torque control (operation to be done later), the important however is that allows the change of diameter on which the various screws are placed (usually to brugola)

but also not. If it exists, and it can be, it will have n bets and if your amateur has more you have to make the second shot. It could be possible by means of an epicycloidal system with variable radius to reach all the centers of the vines but it seems to me a great minkite.
calettatore with 6 screws m5.... dynamometric key and greenhouse alternating the screws.
calettatore with 8 screws m 10 ....idem... and you must change perhaps also the dynamometric key.

Now that you have centered the rays of the gyrophs and faded the caterpillar of every life has already escaped the poetry... .

hi mechanicalmg ... all true, I thought it too, but those had a kind of "cannone" that screwed everything in a blow, shreds of cylinders seem to me ... maybe not in pairs, maybe they were all the same as arrangement in that assembly line, maybe they put them in pairs in a second passage ...

It's complicated, I understand, but something exists... bah, let's see if someone's ever seen stuff like that, even just a little appetizer to start a search... then definitely jumps out that costs an eye and a bang and I abandon everything...

you need to search in google "multiple screwdriver" http://www.fiamgroup.com/pdf/cat/it/1008.pdfare classic compressed air screwdrivers mounted in a variable radius cannon, with or without torque cells, with spring tip so when not taking the hexagon you put in phase and snap inside the caterpillar.
these systems cost because a simple air screwdriver costs about 100 €, then I imagine that the cannon with the braces another 300€.... electronic control 300/400€... patents ...40% gain....you come out according to me about 2000€, a thing not handleable by hand and in the end if you have to close 10 dots a day... do not spoil it more... I would like to be denied.
