Screwing system for screwing e.g. automatic assembly device, has driven shaft movable opposite to drive shaft in opposing directions, and comprising retainer to receive tool, and drive device moving driven shaft in one of directions

摘要

The system (1) has a drive shaft (2) and a driven shaft (4) rotatable with respect to a longitudinal axis (L). Rotating movement of the driven shaft is coupled with rotating movement of the drive shaft via a coupling device (12). The driven shaft comprises a tool retainer (8) for receiving a tool. The driven shaft is movable opposite to the drive shaft in two opposing movement directions (L1, L2). A drive device (10) is provided to move the driven shaft in one of opposing directions. The coupling device comprises two gear teeth e.g. external and internal teeth (22, 42). The drive device is designed as a flow material-operated drive device such as pneumatic drive device.
