Workholding Clamps and Fixturing Solutions
Automated clamping solutions from OK-VISE
OK-VISE currently offers both hydraulic and electric solutions for automated clamping. In our product range, you will find all the essential components for building automated clamping systems – including hydraulic cylinders, electric clamping systems, and a wide selection of clamping components.
Automating OK-VISE clamps is straightforward and flexible. Clamps can be operated automatically either with a hydraulic cylinder or an electric motor – or tightened by a robot using a screw mechanism.
With OK-VISE solutions, you can integrate reliable and efficient clamping into modern automated production environments with ease.
ELVA – Electrical Clamping System
ELVA concept is multi-purpose, resulting in to a design which enables maximum flexibility in automation.
ELVA stands for Extra Low Voltage Actuation. This concept can be used with robotic loading or manual loading of workpieces to machining center.
The design delivers benefits like
- Easy plug and play automation
- Radically shorter production ramp-up times than with traditional clamping automation
- Need for special expertise is avoided
- Safe and clean energy supply with economical coupling and decoupling
Hydraulic clamping
Compared to the other hydraulic systems on the market, the OK-VISE hydraulic clamping module:
- is based on the world-renowned wedge clamp
- has a wedge design that hinders compression of hydraulic oil and prevents vibration
- creates clamping force with a pull stroke
- has a return stroke performed by a spring or hydraulics
- uses a HA-Series actuator designed for 350 bar pressure, hence a compact size
The principle
The operation principle of hydraulically operated OK-VISE fixtures is the same than in electrical ELVA clamping : pulling a bolt down, which pulls the wedge toward fixure base, pushing the jaws against workpieces.
Hydraulic pressure (p) is first converted to the downwards force and by the use of the clamping force of the wedge clamp (F) is applied in two directions. Just like in manual clamping, a stopper is needed on both sides of the clamp.
The simplest way of creating a hydraulic fixture is to use a a single acting hydraulic actuator. Please note that in the double acting hydraulic actuator, pushing force is stronger than the pulling force.
Most typical applications
Retro-fit option
Manual fixtures can be designed in a way that adding automation later is extremely simple, plug-in operation
Installation
Fixturing assembly can be supplied together with the hydraulic actuators. OK-VISE partners from the global distribution network offer assistance with the hydraulic installations. Sample connection diagrams are available from support@ok-vise.com.
Hydraulic actuators
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
