Automatic pneumatic screwdriver for automatic multiple screwing of components.
Specifically it is a screwdriver for fire-fighting nozzles but can be used for various fields.
It is composed of a pneumatic fast clamp which also acts as a spindle that can rotate at a constant periodic step. At each step the pneumatic screwdriver descends and screws the component of the nozzle, then rises, the clamp rotates by one step, and the screwdriver repeats the cycle and this until completing each face of the nozzle.
The speeds and the screwing force are adjustable.
The screwing area is closed by protective barriers.
