INSTALLATION AND OPERATING INSTRUCTIONS:
Manual tool changers, HWR series
8. Setting the clamping force
The clamping force is independent from the quality of the
form fit of the clamping elements of both parts.
This quality is determined by how exactly the locking bolts
7
of the
fixed part
1
can sink into the annular groove
cl
of
the clamping nut
bt
of the loose part
3
.
Both elements are factory set to match each other exactly. The
clamping force, measured at the locking lever
2
, should be
between 30 and 50 N.
The gap dimension
Ⓐ
between the fixed and loose part must
be
0.0 mm
.
A gap between the fixed and the loose part indicates that
inside the element the end face of the clamping sleeve
bt
of
the loose part
3
and of the clamping ring
br
of the
fixed
part
1
are touching each other and thus prevent complete
closure.
In this condition, the energy elements also cannot connect
completely. That results in malfunctions.
The highest clamping force is achieved when the locking
bolts
7
can sink into the annular groove
cl
of the clamping
nut
bt
completely and without play.
DANGER:
Non-compliance may result in severe injuries!
If
multiple loose parts are operated by one fixed part, this adjustment procedure may be carried out only
on the loose parts!
Ö
Otherwise, individual combinations lead to faulty locking.
The fixed part and the loose part must always be completely flat and without gaps when they abut.
►
Risk of accident!
