180o Opening
Angular Grippers Save You Time and Money
New Hyde Park, New York --
A new series of 6 180o
opening angular grippers from Techno-Sommer Automatic is ideally suited
for applications which must be performed within a limited work area. Identified
as the GK Series, they feature stroke-limiting screws to adjust the stroke
between 0o and 180o and have gripping torques ranging from 40 Ncm to 4000 Ncm.
 When
the jaws are completely opened, the work piece can be freed without having
to retract the gripper. This saves valuable cycle time, as well as the
expense of a retraction mechanism or a cylinder. From a fully open position,
the force generated by the jaw tips increases as they near the fully closed
position and become self-locking. Due to the design of the links, a tremendous
closing force is generated. As the jaws open, the mechanism produces significantly
greater velocity at the jaw tips than during the closing stroke. Therefore,
if the jaws are long and heavy, a damping device or throttle valve may
be necessary for the opening stroke. Switch-activating cams (trip dogs)
on the face of the gripper fingers can be used as "open" or "closed" indicators.
The internal linkages are guided by two side plates made from hard anodized
aluminum. As a result, the gripper can handle large side forces. All of
these units are double acting. There are two pairs of air fittings located
on the front side of the gripper. The front connections are factory-sealed
with removable plugs. Either pair of air fittings may be used, depending
on the mounting constraints.
Threaded holes are provided for fastening
the proximity switch mounting blocks. The jaws are made of C45 K
steel, whereas all of the body is constructed from high-strength
aluminum. All jaws are hard anodized and nickel-plated. This guarantees
durability and light weight.
