Clamping force blocks for robot-assisted pallet loading

High clamping force, compact design, low weight - SCHUNK TANDEM plus 140 clamping force blocks are specially tailored for the robot-assisted pallet loading of machine tools. The vises ensure process-reliable workpiece clamping in confined spaces, and open up a lot of scope for the workpiece weight in the handling application.

With their compact square base area of 140 mm x 140 mm, they are particularly suitable for 6-side machining in two set-ups on all common machine tools. The optimized outside contour, a special design of the base jaws and cover strip, minimum clearances and cover plugs for the fastening screws prevent dirt from accumulating or chips and dust from penetrating into the vise.

Any coolant entering is guided outside via a coolant drain hole. Here, a sinter filter prevents the chips from entering the base body. Both the control and the lubrication can be done laterally as well as from the bottom side in all variants. An alignment edge facilitates positioning on the pallet or the machine table.

The one-piece rigid base body, wedge-hook kinematics, and long, hardened jaw guidance provide for concentrated clamping forces in confined spaces, and ensures an excellent repeat accuracy of 0.015 mm. The clamping force blocks are also suitable for milling machining with a high metal removal rate, high number of cycles, and minimum tolerances.

Complete modular system

The SCHUNK TANDEM plus 140 is optionally available with pneumatic, hydraulic or spring actuation: On the one hand as a centric clamping force block with a stroke of 3 mm per jaw; on the other hand as long stroke centric clamping force block with 7 mm stroke per jaw; and finally as a vise with fixed chuck jaw with a 6 mm stroke for automated zero-point loading. Depending on the model, the clamping force is between 15,000 N and 30,000 N.

The modular system thus covers the entire range of possible applications. As the connection dimensions of the long-stroke clamping vises are the same as those of the standard vises, the different variants can be simply exchanged as required. The TANDEM plus 140 seamlessly fits into the more than 50 standard variants of the SCHUNK TANDEM plus clamping force block line. The portfolio covers sizes from 64 to 250 mm.

All vises are suitable both for top jaws with a tongue and groove as well as for chuck jaws with fine serration. A wide range of supporting jaws, top jaws and top jaw blanks for application-specific reworking ensures that the clamping force blocks can be quickly and easily adapted to new clamping tasks.
