8.4 DISASSEMBLING AND MOUNTING TOOL HOLDERS TO CHANGING BUFFERS AND ELASTIC ELEMENT
When the
TOOL HOLDER is disassembled you can change defective parts – elastic element, buffers, etc.
Lift the locking pin (Fig.8.4.1) to dismount the retaining washer (Fig.8.4.2). Take out the screws on the buffers and the nuts of
the elastic element (Fig.8.4.3; Fig.8.4.4). Remove the elastic element from the QC plate (Fig.8.4.5). While the holder is
dismounted
(Fig.8.4.6;
Fig.8.4.7),
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.8.4.8) and
push
the
locking pin
(Fig.8.4.9).
This
will
prevent the
washer from
falling while
mounting the
holder on the
machine.
Make sure the four bolts holding the adaptor
(Fig.8.4.12) are reliably tightened. Mount the
holder on the machine using the same socket as
in 8.3 (Fig.8.4.10; Fig.8.4.11). The retaining
washer fits into the central hole C of adaptor and
the four bolts into the thread holes
Т (Fig.8.4.12).
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 on
the bolts has to be 22...25N.m(16...18 lbf.ft).
