Schunk Intec designs three-finger centric grippers

A Schunk Intec product story
Edited by the Engineeringtalk editorial team Mar 31, 2009

Schunk Intec has created the PZB-plus series of three-finger centric grippers with a central bore designed as a fitting.

The central-bore feature is equipped with female threads for customer-specific add-ons and can be used as an ejector or to supply material.

The PZB-plus can also be used to monitor the handling or assembly process with a camera system or to pick up workpieces and centre them using the fitting during the gripping process.

There are also threads integrated on the upper face of the gripper and on the cover plate to facilitate mounting customer-specific add-ons.

The PZB-plus is available in two different stroke-length versions; the smaller stroke results in approximately double the gripping force.

The six sizes, ranging from 64mm to 200mm, are fitted with multi-tooth guides, as is the case in the PGN-plus and PZN-plus ranges.

Compared with the PZB series, the PZB-plus can pick up 100 per cent-higher torques in directions at right angles to the gripping motion.

This makes it possible to use smaller grippers than before, which allows the system to work more economically.

An optional gripping force safety device is available for the PZB-plus, working with an inner or outer lock.

The position is monitored either via a magnetic switch or inductive proximity switch and the hose-free direct connection is claimed to simplify assembly and installation.

The accessories available for the other '-plus' ranges will also be available for the PZB-plus series.

This includes force measurement jaws, quick-change jaws, valves, sensors or jaw blanks.
