8.8 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.8.8.1) to dismount the retaining washer (Fig.8.8.2). Take out the screws on the buffers and the nuts of
the elastic element (Fig.8.8.3;Fig.8.8.4). Remove the elastic element from the QC plate (Fig.8.8.5). While the holder is
dismounted (Fig.8.7.6;Fig.8.8.7) clean the parts and replace the defective with new ones. Assemble the holder with new buffers
with new screws and new elastic element. Put the retaining washer (Fig.8.8.8) and push the locking pin (Fig.8.8.9). This will
prevent the fall of the washer when mounting the holder on the machine.
Make sure the four bolts holding the adaptor
(Fig.8.8.12) are reliably tighten. Mount the
holder on the machine using the same socket
as mentioned in 8.6 (Fig.8.8.10; Fig.8.8.11).
The retaining washer fits into the central
whole C of adaptor and the four bolts into the
thread holes Т (Fig.8.8.12). The holder is
centered on the outside diameter of the
adaptor. Ensure the connection of the holder
on the forehead 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.8.8.2) 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.
Fig.8.8.13 is 3-d section view of the holder,
showing its parts. The numbering is the same
as in Spare parts.
