Roemheld CLR-1845-F090-R30 | 5 Series Size x 90° cw Direction Double Acting Robust Swing Clamp

Roemheld Robust Swing Clamps-Top Flange, Cartridge Type

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 cartridge version is designed specifically for space-saving manifold mounting.

Clamping Action

Swing Clamps are pull-type cylinders where part of the total stroke is used to swing the piston. 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 Mechanism

Reinforced swing mechanism ensures positive arm position. The safety-clutch mechanism normally incorporated into the 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 & Fluid Supply

Fasten clamp with four socket-head cap screws. Threaded-cartridge clamps have O-ring seals on their outside diameter, so they require a precision mounting hole. Do not use NPT fittings.

Optional Position Monitoring

An accessory unit for pneumatic position control is that the Swing Clamp is in "clamped" position. This simple, reliable unit consists of a stainless steel housing with a spring-loaded control tappet. To operate the tappet, a control bracket must be attached to the rear of the clamping arm. This bracket must be adjusted so that it first contacts the tappet during the downward clamping stroke, after the full swing stroke, at a height where it will not bottom out on the housing at full clamping stroke. When the clamping arm reaches "clamped" position, the pressure control is closed and the pressure built up at the pneumatic port can be evaluated with a differential pressure switch. Parallel connection of up to three controls is possible with a single differential switch
