Field of Application

Advantages & Benefits

💠 Secure, certified gripping force maintenance, GripGuard Holds the gripped workpiece safely and also ensures a permanent gripping force of min. 80% in case of pressure drop.  It also ensures that no dangerous, spontaneous jaw movements can occur in the event of a pressure drop.

💠 Integrated sensor system for precise and process-reliable monitoring of the complete gripper stroke via IO-Link

💠 Large jaw stroke enables flexible handling of a wide range of parts

💠 Dirt protected due to IP 64 as standard and the metal encapsulated, additionally sealed design at the base jaws

💠 Robust interior multi-tooth guidance for high moments and use of long gripper fingers

💠 With food-compliant lubrication as standard as a solution for an easy entry into medical technology, lab automation, pharmaceutical and food industry. The requirements of EN 1672-2:2020 are not fully met.

💠 Fastening on two gripper sides in four screw directions for universal and flexible gripper assembly

💠 Air supply via hose-free direct connection or screw connections
for universal and flexible gripper assembly

Specifications

Functional Description

By applying pressure to the opposing drive pistons, the multi-tooth guided base jaws are directly driven via a drive type fastening.

The jaw stroke is synchronized by means of rack-and-pinion kinematics. This ensures a powerful and centric opening and closing of the gripper.

1. Base Jaw - 
With standardized screw connection diagram for the connection of the workpiece-specific gripper fingers The centering sleeves are attached so that they cannot be lost when exchanging fingers

2.  Multi-tooth Guidance - 
Maximum service life due to lubricant pockets in the robust multi-tooth guidance, and absorption of high forces and torques by means of the large guidance support 

3.  Driver - 
Direct power transmission of the drive pistons to the gripper fingers via a robust drive type fastening 

4.  Kinematics - 
The gear rack-and-pinion kinematics ensure synchronization of the base jaws and centric clamping

5.  Pneumatic Drive Piston - 
Maximum power generation through two oval pneumatic pistons

6.  Dust cover - 
The entire circumference of the gripper is encapsulated with metal and additionally sealed with a lip seal at the base jaws so that it is suitable for universal use, even in
dirty environments.

Application Example

1.  Universal Gripper PGL-plus-P
2.  Deburring spindle RCV
3.  Pneumatic file tool CRT

In addition to ordinary handling processes, the robust and dirt-protected universal gripper PGL-plus-P can also be used to hold workpieces during simple machining operations.

In the example shown, a workpiece is being held between the gripper fingers. A robot moves the workpiece along a stationary deburring spindle for deburring. The connected air purge prevents dirt from entering the gripper.
