2Funktion und Anwendung
Durch Belüftung des Druckluftanschlusses 2
wird der Kolben des Mikro-Parallelgreifers
HGPM-... gegen eineMechanik gedrückt.
Diese Mechanik überträgt die Bewegung des
Kolbens auf die Greifbacken 6. An den Greifbacken werden Greiffinger befestigt. DasÖffnen und Schließen der Greiffinger klemmt
Nutzlasten an der Außen- oder Innenkontur.
Der Mikro-Parallelgreifer HGPM-... ist einfachwirkend und je nach Bauart außengreifend
(bei HGPM-...-EO-...) oder innengreifend (bei
HGPM-...-EZ-...) einsetzbar.
Bei Entlüftung des Greifers sorgt eineRückstellfeder für die Rückführung von Greifbacken und Kolben in dieAusgangsposition:
– Greiffinger geöffnet: bei HGPM-...-EO-...
– Greiffinger geschlossen:HGPM-...-EZ-...

2Function and application
When compressed air is applied to connection
2, the piston of themicro parallel gripper
HGPM-... is pressed against a mechanism.
A mechanism transfers the longitudinal movement of the piston to the gripper jaws 6.
Gripper fingersare fastened to the gripper
jaws. When the jaws open, they can grip work
loads by the inner contour; when the jaws
close, they can grip work loads by the outer
contour.
The micro parallel gripper HGPM-... is singleacting and depending on the mechanism it
can be used for gripping from the outside or
from the inside.
When the gripper is exhausted, a reset spring
returnsthe gripper jaws to the starting position:
– gripper fingers open: on HGPM-...-EO-...
– gripper fingers closed: on HGPM-...-EZ-...

Fastening the gripper fingers
SUse gripping fingers as short and as light
as possible.
SScrew two fastening screws into the
threaded holes in each of the gripping
jaws.
The maximum screw depth must not be
exceeded. Otherwise the function can be
affected.
The different gripping jaws have the following connection threads:

Fitting theHGPM-...
Please note
High acceleration forces in the longitudinal
direction of thegripper (e.g. when fitted on
moving parts such as the DGP-...) reduce
the gripping force.
S Make surethat the resulting work load

5Commissioning
Completesystem
SSlowly pressurize your complete system.
This will prevent any uncontrolled movements.
The safety start-up valve type HEL-... or
HEM-... can be used for slow pressurization during the starting phase.
Individual unit
SObservethe permitted values for the following (see catalogue):
– the maximum gripper force as a factor of the lever arm and the eccentricity
– the maximum permitted gripping times
– the maximum gripper finger weight force.
Warning
Moving parts can causeinjury to hands
and fingers.
S Therefore make sure that:
– nobody can place his/her hand
between the gripper fingers
– no objects liewithin therange of the
gripper fingers.

SStart a test run
– at first with slow positioning movements
– then under application conditions.
The HGPM-... must hold the work load securely.
SConclude the test run.
The gripper should now be exhausted.
