The grippers UG 20 and UG 25 consist of the cylinder casing (1) and the jaw casing
(2). The two casings are firmly connected with each other and cannot be separated.
The pneumatic cylinder (1) which transmits its movements to the grip jaws (3) via two
reversing levers operates in the pneumatic cylinder. The grip jaws (3) move parallel
with each other. The grip mechanism is protected from dirt and dust by the cover
plate (11).
The grippers are available as type NN (without spring preload), NC (pressureless,
closed) and NO (pressureless, open). They change of design is not possible.
To query the gripping positions and depending on the requirement up to three
magnetic sensors (accessories) as well as up to two inductive sensors (accessories)
can be installed either in the C-grooves (4) or in the holder (5). Thus the gripper can
check up to 5 positions.
One possible application is the query „Gripper open“, „Gripper closed“ and „Part
grip
ped“. When positive grip fingers and asymmetric parts are used it is also possible
to check whether the part is held in the correct position in the gripper.
The inductive sensors are covered by the set screws (6). Loosen the fastening
screws under the cover (7) to adjust the set screws (6) and then retighten the
fastening screws.
The 4 threads (10) can be used to install holding-down devices or similar add-on
parts.
