8.5 DISASSEMBLING AND MOUNTING TOOL HOLDER TO CHANGE BUFFERS AND ELASTIC ELEMENT
When the TOOL HOLDER is
disassembled you can change
defective parts – elastic element,
buffers, etc.
Lift the locking pin (Fig.8.5.1) to
dismount the retaining washer
(Fig.8.5.2). Take out the screws on
the buffers and the nuts of the
elastic element (Fig.8.5.3;Fig.8.5.4).
Remove the elastic element from
the QC plate (Fig.8.5.5). While the
holder
is
dismounted
(Fig.8.5.6;Fig.8.5.7), clean the parts
and replace any defective ones with
new ones. Assemble the holder
with new buffers, new screws, and
new elastic element. Replace the
retaining washer (Fig.8.5.8) and
push the locking pin (Fig.8.5.9). This
will prevent the washer from falling
while mounting the holder on the
machine.
Make sure the four bolts holding
the adaptor (Fig.8.5.12) are
reliably tighten. Mount the
holder on the machine using the
same socket as mentioned in 8.2
(Fig.8.5.10;Fig.8.5.11). The
retaining washer fits into the
central hole C
of adaptor and the four bolts into the thread holes
Т (Fig.8.5.12). The holder is centered on the outside
diameter of the adaptor. Ensure the holder is
properly connected to the plate of the adaptor and
then tight evenly the four bolts.Tightening force of
the bolts has to be 22...25N.m(16...18 ft/lbs).
Mounting the holder without retaining washer
(Fig.8.5.2) is
INADMISSIBLE
because the security
system preventing the separation of part of the
holder in case of broken buffers and elastic element
will not function!You can change the butterfly of the
holder without dismounting the holder of the machine.
You can change the butterfly of the holder without
dismounting the holder of the machine. Fig.8.5.13 is a 3‐
D section view of the holder, showing its parts. The
numbering is the same as in Spare parts.
