6.4 Coupling Interface

The NSR maxi 220 robot coupling has two different alignment aids
for the PKL pallet coupling.
The mounting interface for the clamping pallet is identical for both
versions of the pallet couplings.

Torque pin version I

Here, the pallet coupling is aligned with the robot module using
the slanted contact surfaces. The wedge slants on the pallet
coupling center precisely with the machining contour of the robot
module during assembly.

Note:

 The PKL maxi 220 pallet coupling can only be coupled using

torque pin version I.

Torque pin version II

The pallet coupling engages in the fitted bushings of the robot
module using alignment pins during joining.
