Description

Roemheld Compact Swing Clamps-Flange Base-Single Acting

5000 psi max
Single Acting

Swing Clamps utilize a sturdy helical-cam mechanism to swing the clamping arm clear for unrestricted loading. The Compact Swing Clamps shown here are extremely small, economical clamps suitable for many applications. Clamping arm can be mounted to start its 90 swing from any position within 360. The flange-base version provides many plumbing options, including manifold mounting.

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 fluid pressure swings arm 90 over workpiece then clamps down. The single-acting version shown here has a fast, totally dependable spring return that lifts the arm, then swings it back 90 for loading/unloading.

Design Considerations

Due to their small size, these 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. To be safe, use low operating pressure during initial setup.

Do not exceed maximum fluid flow rate in table. For extended clamp life a simple flow-control valve may be required if the fixture is powered by a high-flow-rate power source and only contains a few clamps. Clamping time should be at least one second.

Mounting Fluid Supply

Version 1: Standard Fittings

Version 2: Manifold Mounting

Version 1, for standard fittings, has a 1/8″ BSPP port (two for double-acting clamps). Version 2, for manifold mounting has O-ring ports underneath instead of standard ports. Do not use NPT fittings. For manifold mounting, the mounting surface must be ground flat to ensure proper O-ring sealing.

Both clamp versions can be fastened to the top of a fixture plate with four socket-head cap screws inserted through the flanged base from above. Version 2 clamps, with standard fittings, can alternatively be mounted:

a) Through a bored hole in the fixture plate, fastening with four socket-head cap screws inserted through the flanged base from below

b) Through a tapped hole in the fixture plate, securing with a lock ring

c) Through a bored hole in the fixture plate, securing with one or two lock rings.
