Single and Double Acting
FEATURES: These pull clamps can be used to make a combination locator and clamp by adding a custom locating pin. The 55mm counter-bored hole is a reference diameter to accept custom locators. The plunger has an extended key at the bottom to act as an anti-rotation device, for applications where plunger orientation is important to provide machining clearance. These versatile clamping modules provide considerable force in a small size, and can be placed very close together. Ordering the Threaded-Body Clamping Module in this mounting block allows using standard fittings instead of manifold mounting, and requires much less machining to install.
SIZES: Available in one size, which can be used as single acting or double acting — see Dimensions page for part number. Push force at 7500 psi:
CLAMPING ACTION: Applying fluid pressure pushes the piston down, pulling down a drawbar inserted in the centre hole. Spring return (single acting), with the option to add a return pressure line to use as double acting.
CLAMPING WITH A "C" WASHER: Clamping can be accomplished using a drawbar and C Washer. This method provides maximum clamping force, but has some disadvantages. The C Washer is a loose part that must be handled each time a work piece is loaded. Also, the C Washer can interfere with machining operations on the top side of the work piece.
CLAMPING WITH A POLYURETHANE SPRING: Clamping can also be accomplished using a drawbar to compress a polyurethane spring that is slightly smaller than the inside diameter, to apply clamping force from the inside. Note: this method still requires a locating pin to provide location for the inside diameter. Clamping force depends entirely on the spring material, with the plunger going through its full .236" stroke.
MOUNTING: Locate each clamping module in exact position using the 55mm counter-bored hole as a reference diameter. Once in proper location, fasten clamping module to fixture with four socket-head cap screws.
FLUID CONNECTION: Two 1/4" BSPP ports. Do not use NPT fittings.
CONSTRUCTION: Plunger > Steel, case hardened. Body > Steel, black oxide finish. |
