Function
Before clamping components with the zero point clamping system it is important to ensure
that no fragments or other foreign bodies are in the system. This applies in particular to the
hole for the alignment bolt and the base plate, which must be clean.
The holes for the alignment bolt and indexing cylinder pins in the base plate are made in a
unique half-shell shape.
This makes it possible to clamp the respective components quickly and truly aligned to the
base plate.
By operating the clamping screw
-a-
(approx. 4 turns) the clamping bolt
-b-
is pushed into the
groove
-c-
of the alignment bolt. In this way the alignment bolt is pushed into the half-shell
shape.
The slanting surface at the locking groove has the effect of pulling the locating bolt and
hence the component to be clamped downwards on to the base plate.
With a clamping torque of
30 Nm
at the clamping screw a maximum down force of
20 kN
is
achieved. Exceeding the maximum torque results in damage to the clamping mechanism.
When changing the clamped component, the clamping bolt is completely retracted from the
groove in the alignment bolt using the clamping screw (turn until the stop is reached).
Sequence of operation:
In order to achieve the best
possible repeat accuracy, it
is best to always keep to
the same clamping
sequence when changing
components.
