Robust Swing Clamp – Cartridge
Position monitoring optional
- available in four clamp sizes
- double acting only
- 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
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 Mechanism
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 & 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. Carefully follow hole-preparation instructions in the drawings. Fluid passages must be drilled exactly as shown in the drawings. Do not use NPT fittings.
Order clamping arm separately – see clamping accessories. 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).
Optional Position Monitoring
An accessory unit for pneumatic position control is available to monitor 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.
Optional Metallic Wiper
This optional, additional wiper protects the FKM wiper against physical damage, e.g. by hot chips. These Swing Clamps are ready for mounting the metallic wiper, which consists of a radially floating wiping disk and a retaining disk that is pressed onto the existing collar. Clamps can be ordered with the metallic wiper already installed, or the metallic wiper can be ordered separately.
