Schunk: Quick-Change Pallet System
Clamping module.
Morrisville, NC — New from Schunk is the VERO-S quick change pallet clamping module made entirely of hardened Stainless Steel. The pull-in force of the new module is up to 9,000 lbs. With the new module, machine setup times can reportedly be reduced by up to 90 percent. The new product can provide more precision, efficiency, process reliability, and setup reduction in metal cutting.

The patented dual clamping stroke and the integrated turbo function provide a retention force that increases to 9,000 lbs. — 30 percent higher than the company's previous model. The rigidity of the clamping system benefits from this higher force. As a result, considerably higher cutting forces are possible. Even extremely high shear forces can be absorbed reliably. Locking of the new quick-change pallet system is done mechanically with a large spring package. It is self-locking and clamps with a form-fit. Holding forces of up to 16,800 lbs are achieved. For opening the module, a pneumatic pressure of 6 bars (85 psi) is sufficient.

The device clamps workpieces, pallets, clamping stations, existing fixtures, and tombstones with one or more clamping pins. The radial aligned clamping slides of the quick-change pallet system pulls in the clamping pin and locks it. Exact positioning is accomplished with a short taper. Radial location is done with a diamond pin. This assures a repeat accuracy of less than 5µ (0.0002-in.).

The new VERO-S is completely compatible and interchangeable with the company's previous pallet system and the clamping pins work universally across the new line. Workpieces can be transferred from machine to machine or to a CMM accurately and seamlessly on the fly. Hardened Stainless Steel is used for all of the functional components, such as base body, clamping pin, and clamping slide. This increases the module's life and reliability, while reducing maintenance.

The maintenance-free module is completely sealed and protected against the penetration of chips, dust, and coolant. Integrated into the standard module is an air purge connection, which can also be used for part recognition. The position of the clamping slide can also be monitored by using an air purge monitoring system. Each module is compatible for automated loading out of the box. Since the module is equipped with bottom and lateral air connections, it is completely flexible in its mounting.
