Patent ID: 8751046

Claim:
A working device for a multiaxial robot hand with a rotatable hand housing and with a driven member rotatable thereon, the working device comprising: connections for the driven member; a tool connected to said connections; an additional device connected to said connections; a rotary connection coupling comprising: a coupling housing with coaxial flanges, which are connected in a rotationally engaged manner and form said connections for the driven member to said tool; a rotary part, which forms the connection for said additional device, said rotary part being mounted rotatably at said coupling housing and said rotary part being rotatable coaxially with said coaxial flanges; and a moveable coupling element connected to said coaxial flanges and to said rotary part, said moveable coupling element being moveable to a position establishing a first coupled state, with said tool and said additional device coupled and rotating together, whereby the driven member rotates both said tool and said additional device and said moveable coupling element being moveable to a position establishing a second coupled state with said tool and said additional device rotatable in relation to one another, whereby the driven member rotates only said tool and said additional device is stationary relative to the hand housing.
