OK-VISE® Fixturing Concept

Hydraulic modules

Hydraulic actuator sets HA-JB1, HA-JD1, HA-VB1 and HA-VD1

In addition to hydraulic actuators (= cylinders) these sets include all the adapter bolts and fittings required to automatize B- or D-series clamps.

Depending on the clamp size, a 8 mm or 12 mm bolt goes through the clamp and fixture plate to the cylinder ‘s piston. The base cylinder is bolted on to a fixture plate.

The cylinders in the sets are single-acting, enabling the simplest possible actuation of OK-VISE clamps

Powerplate concept

The Powerplate concept gives users the most straightforward access to automation.

Hydraulic actuators (from 1 to 7 pcs) are built-in under a base plate, and the cylinder package can also be moved to various additional positions under the plate for optimal clamping. So,either a single workpiece can be clamped alone or up to 14 pcs simultaneously.

The Hydraulic actuator normally uses HA-VD1, creating a 29 kN clamping force with 350 bar maximum hydraulic pressure.

Fixtures can also be built on sub plates, which can be rapidly changed using a built-in Ball-Lock quick-change system.

Generic-purpose OK-VISE Fixturing Concept components like Multi-Rail RM units can be installed directly on the plate.

There are two sizes as standard: 240x400 mm and 400x700 mm.

Plate size 240 x 400 mm.
Hydraulic cylinder package ( 2 actuators ) can be installed in the middle or at the end of the plate.

Positioning holes for RM-400 Multi-Rail units are included.
