With the MPG-plus Miniature Parallel Gripper, SCHUNK brings about new solutions for the handling of small components. Compared with similar modules which require the same input, the new SCHUNK gripper for small components achieves a considerably higher output, clearing the way for smaller and more efficient systems. At the Automatica show 2010, this power gripper received the MM Award in the category "gripping technology" of the renowned magazine MM MaschinenMarkt.
The combination of an oval piston drive and roller bearings assure an enormous degree of efficiency for this compact powerhouse, and makes it to the most efficient miniature parallel gripper on the market. Due to the high force and moment loads, units of the same size can be equipped with longer gripper fingers and higher gripping forces are achieved. Alternatively, design engineers and operators can work with a smaller size at an identical power requirement. If the gripper should be equipped with micro valves, the actuation time can increase by up to 100 per cent. This booster in productivity saves valuable compressed air, and annoying assembly work.
Up to 25 % higher gripping forces
Compared with the previous MPG, the gripping force of sizes 40 increased from 110 amounts to 140 N, which is an increase by 25 per cent. The maximum admissible finger length is now 60 mm, instead of 40 mm. In other words, instead of size 50, size 40 will be enough for future applications.
By increasing the number of the cross roller guidances, the force is distributed more evenly, making the average basic load rating increase by 30 percent. This causes the bearing capacity of the complete guidance to improve, wear-out is reduced, which boosts the life of the gripper. For achieving a much higher precision, the roller guidances are individually adjusted. This makes them very stable and able to run smoothly
