Plug & work gripper from Schunk for Universal Robots

Yderligere beskrivelse

Gripping force

is the arithmetic sum of the individual force applied to each jaw at distance P (see illustration).

Finger length

The maximum permissible finger length applies until the nominal operating pressure is achieved. With higher pressures, the finger length must be reduced proportionally to the nominal operating pressure.

Repeat accuracy

is defined as a distribution of the end Position for 100 consecutive strokes.

Actuation

Control via digital I/O

Workpiece weight

is calculated for force-fit gripping with a coefficient of static friction of 0.1 and a safety factor of 2 against workpiece slippage at acceleration due to gravity g. For form-fit or capture gripping, there are significantly higher permissible workpiece weights.

Closing and opening times

are purely the times that the base jaws or fingers are in motion. Valve switching times, hose fill times, or PLC reaction times are not included, and are to be considered when cycle times are calculated.
