AIR-POWERED SWING CLAMPS

 


Flange Base




 
100 psi max (Air)
Double Acting


FEATURES: Air-operated version of our popular hydraulic Swing Clamps, for applications requiring light clamping force. Arm swings clear for easy loading. Sturdy helical-cam mechanism. Arm can be mounted to start its 90° swing from any of four positions, 90° apart. Flange-base version provides many mounting options.

SIZES: Available in six sizes, each with a choice of clockwise or counterclockwise swing — see Dimensions page for part numbers. Clamping force at 100 psi with standard arm:
 20 Lbs   (2 series)
 41 Lbs   (3 series)
 107 Lbs   (4 series)
 167 Lbs   (5 series)
 227 Lbs   (6 series)
 466 Lbs   (7 series)

CLAMPING ACTION: 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 air 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.

OVERLOAD PROTECTION: Air-Powered Swing Clamps do not have overload protection; therefore the swing motion must not be restricted in any way. Be sure to adjust the contact bolt so that the clamp completes its full swing stroke and starts its clamping stroke before contacting the workpiece.

DESIGN CONSIDERATIONS: Do not use with hydraulic fluid. Use an Air Check Valve between the air supply and the Air Clamping Valve to protect against pressure loss if the air supply fails. For extended clamp life, install an Air Extractor Dryer before the Filter/Regulator/Lubricator. A simple flow-control valve may be required to control clamping speed if clamps are powered by a high-flow-rate air supply. Clamping time should be at least one second.

MOUNTING: Several possible mounting methods: 1) fasten to top of fixture plate with four socket-head cap screws inserted through the flanged base from above; 2) Mount through a bored hole in the fixture plate, fastening with four socket-head cap screws inserted through the flanged base from below; 3) Mount through a tapped hole in the fixture plate, securing with a lock ring; 4) Mount through a bored hole in the fixture plate, securing with one or two lock rings.

CLAMPING ARM: A standard-length clamping arm with an adjustable contact bolt is furnished with each clamp. Order optional long arm (87 psi max) separately. Additional arm extensions will further reduce operating pressure (inversely proportional to arm length).

CONSTRUCTION: Housing, piston, and arm > Steel.
