Carr Lane CLR-3548-070 | 40.00mm Width Fixture Clamp - Fixed Jaw

Product Information

3600 psi max Double Acting Fixture Clamps are extremely compact, high-precision power vises designed to be incorporated into workholding fixtures. Unlike standard vises, Fixture Clamps do not have a leadscrew for adjustment – instead using exchangeable, machinable clamping jaws that must be custom sized for the workpiece. Slim, solid vise body with high-rigidity and complete protection against dirt and chips. Manifold mounting is standard for maximum compactness and mounting flexibility, but fluid can alternatively be supplied using standard fittings by adding an optional Adaptor Plate. The fixed-jaw version shown here has a fixed reference jaw and a sliding jaw, available with either a standard stroke or long stroke. This is the smaller of two sizes, with 40mm jaw width, providing the following clamping force at 3600 psi:          2100 lbs

Clamping Action

Applying fluid pressure to the A (clamping) port advances an integral hydraulic piston which actuates the sliding jaw. Switching pressure to the B (unclamping) port returns the piston, pulling the sliding jaw back to its unclamped position. Fixture Vises can only be used to clamp inward, on the exterior of a workpiece.

Design Considerations

Fixture Vises can only be used for exterior clamping. Every 500 clamping cycles, the clamping slide should be lubricated using port S provided for central lubrication. Never use up the entire clamping stroke, to ensure safe clamping of the workpiece with full force. Clamping jaws should always rest against the end supports, because the fastening screws alone cannot resist the maximum clamping forces.

Mounting & Fluid Supply

Fixture Vises have two locating holes underneath for dowel pins, to provide precise alignment on a fixture plate. Fasten from below with eight socket-head cap screws (Mounting Option 1). If fastening from below is not possible, or to use standard fittings instead of manifold mounting, order the optional Adaptor Plate (Mounting Option 2 or 3). Self-Centering Fixture Vises can be mounted in any position, horizontal or vertical. Fluid is supplied to manifold ports A and B underneath the vise through drilled passages in the fixture (install two CLR-9210-132-F Connecting Inserts). O-ring port S is provided for central lubrication of the clamping slide. O-ring port L is provided for optional pneumatic seat control on the fixed jaw. Do not use NPT fittings.

Clamping Jaws

Because Fixture Vises do not have a leadscrew for adjustment, clamping jaws must be custom sized for the workpiece. Exchangeable, machinable blank clamping jaws (4130 steel) are sold separately. Also see dimensions of user-manufactured jaws.
