Part Placement Devices are designed to provide a low cost gripping
unit for use on transfer mechanisms. These air operated units grip
parts internally or externally offering the designer a wide latitude
in finger tooling arrangements.
in two or three finger grip models, DURA-GRIP units are ruggedly
constructed with a minimum of moving parts. Utility tapped holes
permit mounting the unit from the top or the side with additional
cap styles for dovetail mounting. These same holes can be used to
mount "stripper" devices too. All units are shipped completely
assembled, ready for mounting and attaching tooling.
body is anodized high strength aluminum, fingers are hardened tool
steel. Maximum pressure, 100 psi. HD heads are available in all
sizes of the GH series. These heads' toggle linkages are arranged
to have the inward motion of the finger occur on the full (bore)
side of the piston. Consult factory for gripping forces. An optional
finger positioning sensor is available on all heads. The built-in
proximity switch can be set to indicate either fingers opened or
Here to see how the Dura-Grip Works
of the DURA-GRIP unit must be controlled by a 4-way air valve in
the transfer mechanism. The air valve directs the air into the lower
chamber port where the air pressure forces the piston to rise, thereby
opening the fingers. Next, the air valve directs the air into the
upper chamber port moving the piston down to close the fingers.
bottom adjusting screw can be set to stop the downward travel of
the piston thereby adjusting the closing of the fingers.
dovetail mounting heads, a top adjusting screw adjusts the opening
of the fingers. Maximum finger holder movement is 5° (10°
included angle). "W" models are also available giving
10° (20° included angle).
models have a double extended piston rod extending through the bottom
cap. This gives greater stability and longer life where tooling
loads are heavy.
heads are available with one fixed and one moving finger. Consult
factory for details. External dimensions remain the same.
