Cylinder Head
PC Controlled Positioning and Fastening System
The system is
designed to carry out accurate fastening of cylinder head bolts with
a single tool used by one operator over a sequenced fastening
cycle. The engine is interlocked into station, the build card
is scanned and a socket select system clearly shows the correct
socket to be used. A PC screen layout of the cylinder head bolts is
displayed, with the next bolt in the fastening sequence clearly
identified. The tool position is tracked by the system and is shown
on the display. Once the tool is in the correct position over the
correct bolt, it is enabled and the bolt can be fastened to the
correct torque and angle setting. The tool will only be enabled once
all the control conditions are met. Once the bolt has achieved a
successful fastening cycle the tool is disabled, the system shows
the next bolt in the fastening sequence, if a different socket is
required this is clearly shown. The tool can now be positioned to
the next bolt and so on until all the head bolts are secured for
that particular fastening stage. Once all bolts are secured the
system automatically changes the torque setting for any further
stages. Should any individual bolts require a different setting the
system identifies them by their position and automatically selects
the correct setting. Once an engine has successfully completed a
cylinder head the interlock is released and the engine can be
removed from the work station.
This system is
currently configured for 5 different engine types and can be configured
for many more. The same type of system is currently utilised on Main
Bearing and Con-Rod assembly areas for 5 different engine types.
Based on the success of these systems another complete system has
recently been installed. |
