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).

Material 

Piston > Alloy steel, nitrated for wear and corrosion resistance. Housing > Mild steel, nitrated for wear and corrosion resistance. Piston rod wiper > FKM. DFARS and RoHS compliant.

Advantages

● 5 sizes available ● Compact design partially recessible ● High clamping force at low pressures ● Sturdy swing mechanism ● Insensitive against high flow rates ● Indexing of the clamping arm in a specified position is possible ● Special swing angle easily realizable ● Standard FKM wiper ● Metallic wiper optional ● Screw counterbores coverable ● Position monitoring available in six variants ● Hydraulic and pneumatic ports integrated in the flange ● Mounting position: any

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.
