Robust Swing Clamps Top Flange 5000 psi max Double Acting Sturdy
Swing Mechanism
Product Information
5000 psi max
Double Acting
Swing Clamps utilize a sturdy helical-cam mechanism to swing the
clamping arm clear for unrestricted loading. The Robust Swing
Clamps shown here are compact, economical, heavy-duty clamps with a
reinforced swing mechanism and a heavier clamping arm to exert high
clamping force in relation to clamp size – especially important at
lower operating pressures (450 to 5000 psi operating range). Robust
Swing Clamps are also ideal when using longer, heavier custom arms.
An integral flow-control orifice allows using high-flow-rate power
sources without separate flow restrictors. Arm can be mounted to
start its 90° swing from any position within 360°. The top-flange
version shown here allows low-profile mounting, using either
standard fittings or manifold mounting.
Available in five clamp sizes, double acting only, with a choice of
clockwise, counterclockwise, or zero° swing. Available with 45° and
60° swing angles by special order. Clamping force at 5000 psi with
a Standard Clamping Arm:
Clamping Arm
Swing Clamps are pull-type cylinders where part of the total stroke
is used to swing the piston, and the remaining stroke is available
as the clamping range. Applying fluid pressure to the A (clamping)
port swings arm 90° over workpiece then clamps down. Switching
pressure to the B (unclamping) port positively lifts arm then
swings it back 90° for loading/unloading.
Reinforced Swing Mehanism
Reinforced swing mechanism ensures positive arm position. The
safety-clutch mechanism normally incorporated into our swing clamps
is omitted in this design. In case the workpiece hits the clamping
arm during loading, the angular position of the swing-clamp arm
will be exactly maintained. Using a longer, heavier clamping arm
will also not declutch the swing arm and affect arm position.
Mounting and Fluid Supply
Dual mounting capability allows any clamp to be mounted using
standard fittings or manifold mounting. Two 1/4" BSPP ports. For
optional manifold mounting, use the O-ring ports underneath,
instead of the standard ports. Do not use NPT fittings. For
manifold mounting, the mounting surface must be ground flat to
ensure proper O-ring sealing. Fasten clamp with four socket-head
cap screws.
Clamp Arm
Order clamping arm separately below. Maximum allowable operating
pressure is 5000 psi. Longer, custom clamping arms will reduce
allowable operating pressure, inversely proportional to arm length.
Optionally, the clamping arm can be positively keyed to the piston
rod in a fixed 90° position by inserting an indexing pin (order
separately).

Application
Hydraulic swing clamps are used for clamping of workpieces, when it
is essential to keep the clamping area free of straps and clamping
components for unrestricted workpiece loading and unloading. Due to
the sturdy swing mechanism and the manifold possibilities of
position monitoring these swing clamps are particularly suited for
• Automatic manufacturing systems • Clamping fixtures with
workpiece loading via handling systems • Transfer lines • Test
systems for motors, gears and axes • Assembly lines • Special
machine tools
Description
The hydraulic swing clamp is a pull-type cylinder where a part of
the total stroke is used to swing the piston. The favourable area
ratio (piston/piston rod) allows high clamping forces already at
relatively low oil pressures. Due to the sturdy swing mechanism the
angle position of the clamping arm remains the same after a slight
collision with the workpiece during loading or unloading. Also a
collision during the clamping process is not critical. When using
high flow rates the swing speed is limited by installed throttle
points. The FKM wiper at the piston rod can be protected against
coarse and hot swarf by an optionally available metallic wiper .
The different possibilities of the position monitoring are
presented at the side.
