BESONDERHEITEN: 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. Manifold mounting allows an extremely compact, space-saving design.
GRÖßEN: 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:
SPANNBEWEGUNG: 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.
SPANNEN MIT VORSTECKSCHEIBE: 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.
SPANNEN MIT POLYURETHANFEDER: 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.
MONTAGE: Clamp should be recessed into the fixture as shown in the installation drawings. Carefully follow hole-preparation instructions in the drawings. The overall depth of the bored hole must be strictly observed, because the bottom acts as a stop (to make the short length of this unit possible). The insertion chamfer and the entrances of the fluid passages into the bored hole must be rounded to avoid damaging the seals during clamp installation.
HYDRAULIK-ANSCHLUSS: Fluid passages must be drilled exactly as shown in the drawings. Do not use NPT fittings.
KONSTRUKTION: Plunger > Steel, case hardened. Body > Steel, black oxide finish. |
