Sectional diagram Base jaws for the connection of workpiece-specific gripper fingers Drive principle of pinions and racks for high power transmission and centric gripping Housing weight-optimized through application of hardanodized, high-strength aluminum alloy Robust bearings for precise gripping with minimal play at a high load capacity Functional description The base jaws are driven and synchronized by applying pressure to opposite sides of each piston which then translate the linear motion into rotary motion via a rack and pinion. Options and special information Workpiece dimensions and workpiece weights By having indexable fingers, the gripper is extremely flexible and able to handle a wide range of workpiece sizes. Furthermore, the base jaw lengths and finger diameter are adjustable based on the required grip force or dimensions of the workpiece. Please contact us for further details.

General note to the series Gripping moment Gripping moment is the arithmetic total of gripping moments for each claw jaw. Finger length is measured from the upper edge of the gripper housing in direction to the main axis. If the max. admissible finger length is exceeded, the speed of jaw motions have to be reduced and/or the opening angle has to be diminished, as it is done with heavy fingers. The service life of the gripper can shorten. Repeat accuracy is defined as the spread of the limit position after 100 consecutive strokes. Workpiece weight is calculated for a friction grip using a coefficient of friction of 0.1, the given finger length and workpiece dimension and a safety factor of 2 to prevent against workpiece slippage due to gravity. Considerably heavier workpiece weights are permitted when using form-fitted fingers. Closing and opening times are purely the times that the base jaws or fingers are in motion. Valve switching times, hose filling times or PLC reaction times are not included in the above times and must be taken into consideration when determining cycle times.

If the maximum admissible finger weight is exceeded, throttling is necessary in order to ensure a smooth jaw motion without jerks or bounces. The lifetime may reduce.

Considerably heavier workpiece weights are permitted when using form-fitted fingers. The gripping force can be seen as a function of the base jaw position (BS1/BS2), the gripped workpiece diameter and the finger length, L. The finger length is measured from the top of the gripper housing to the gripping force application point.
