DURA-TRANS
Pick-and-Place Transfer
Device is designed to provide an economical and efficient
part transfer mechanism. Sturdy and compact in construction,
the unit is operated by a pneumatic rotary actuator
controlled by a 4-way air control valve. The unique
slotted cam with three cam followers provides a smooth
transition of rotary motion to linear movement.
QUALITY CONSTRUCTION
Dual rods are used
in both horizontal and vertical planes to ensure smooth
movement and positive alignment. Rod bearings are oil
impregnated bronze bushings which eliminate the need
for relubrication. Neoprene seals are provided to protect
the bushings from atmospheric dirt. Bronze bushings
are utilized rather than ball bearings because bushings
distribute the weight over a larger surface area. This
results in less wear on the slide rods. Horizontal stroke
adjustment is by the external link arm. Vertical stroke
adjustment is by an adjustable stop screw. The adjustable
stop screw has a built-in hydraulic plunger arrangement
to cushion the shock of the body as it ends its downward
stroke.
TOOLING VERSATILITY
The tool mounting
block is supplied blank. Sufficient material has been
provided between the rod bores and the front face of
the block to permit drilling and tapping holes for attaching
fingers. In addition, the tool mounting block can be
repositioned on the horizontal rods to compensate for
any misalignment when mounting the
DURA-TRANS unit.
Available as optional
equipment is the R&l Dovetail Bracket Kit DB-20
which accepts DURA-GRIP Model GH-21A or GH-22A
Part Placement Devices. This dual dovetail bracket arrangement
permits three finger adjustments: side-to-side on the
horizontal rods, up-and-down with the dovetail bracket
and front-to-back with the dovetail gripping device.
