Today’s coupling systems have to be light, extremely stiff and self-locking. In addition, they must be able to be monitored electrically and operated as intuitively as possible. You can avoid the disadvantages of electromechanical or hydraulic clamping systems. Hydraulic systems require extra supply lines and pump systems and are maintenance-intensive.

Electromechanical versions, on the other hand, have other disadvantages. They significantly increase the overall weight of the couplings and can be problematic in the event of a power failure. The high gear ratio can make it difficult to loosen the coupling parts.

JAKOB Antriebstechnik offers profile rail couplings that can be easily used in connection with all common profile rails. They are attached either directly or using adapter plates to existing profile rails from various manufacturers and are therefore also ideal for

Retrofits. The separation to the interchangeable rail can take place in a vertical (PKV series) as well as horizontal (PKH series) direction. The patented force-amplifying wedge clamping mechanism easily closes a joint gap of up to 5mm between the active and passive part. These clamping kinematics ensure a high degree of rigidity and precision of the connection. The clamping force generation is guaranteed by an electrical clamping status query and a minimum clamping force in the event of a pressure drop.

The types PKH and PKV can be adapted to all common gripper rail profiles. In addition to the pneumatic-automatic variant, there is also a manual-mechanical version of the coupling systems in the portfolio. These are conventionally fixed with a screw. For the manual application of the clamping force, they have a double screw drive which actuates the clamping piston. The couplings even close five millimeter wide gaps between the active and passive parts automatically and are queried electrically.

It is installed in the gripper rails either directly or using simple adapter plates. In addition, energy couplings can be attached to the automatic systems. ‘With the closing process, these establish the electrical and pneumatic connection to the interchangeable rail.’ The advantages are obvious: The pneumatic solution TYPE PKH-P or PKV-P is light and like hydraulic systems independent of power failures, but is low-maintenance and economical like couplings with an electric drive. In use, the gripper couplings ensure significantly shorter set-up times – and thus increase the productivity of the entire system.

PKV – design features:

The coupling consists of a passive and an active part made of heat-treated steel. In the active part, the clamping force is generated by an axially displaceable locking bolt and a mechanical clamping gear. With this structure, high clamping forces and high dynamic rigidity are achieved with low mass. A vertical lifting stroke “K” (see data sheet) is necessary for the tool change.

The PKV series is designed for vertical coupling processes and is available both as a fully automatic, pneumatically operated version PKV-P and as a PKV-M series with simple manual operation.

PKH – construction features:

The PKH series corresponds to the PKV series, but is designed for horizontal clamping processes. It is also available in a pneumatic version (PKH-P) and a manual version (PKH-M).

PKP – design features:

The PKP series is a vertical linear coupling with manual operation. The clamping process is achieved by tightening a screw. The production from aluminum makes the series more cost-effective.
