New
Automatic Piston Ring Assembly With Pick-And-Place From City Machine
Is Proving Ideal For Large Diesel Pistons
MUNCIE,
IN — The new fully automatic Piston Ring Assembly System with
gantry pick-and-place is proving ideal for automatic ringing of large
diesel pistons. It is the only automatic piston ring assembly on the
market that features single, rather than two-step, loading of the oil
control ring and coil spring, a major innovation in piston ring assembly.
The new system handles complete assemblies — piston connecting
rod, piston pin and skirt assemblies — installing the fire ring,
compression ring and oil control ring assembly in one three-stop operation.
In addition, during the ringing process the piston does not touch any
reference surfaces and absolutely no machine parts touch the piston dome,
a critical feature that eliminates damage to the dome during the process.
An expanding cone, a proprietary City Machine innovation, maintains full
contact with the ID of the ring and allows the rings to be opened gradually
and consistently. The expanding cone eliminates the three-point contact
and the pushing and pulling on the ring usually found in other piston
ring loaders.
Another key advantage of the new system is that rings can be loaded while the
machine is cycling, so the system need not be stopped at any point. The system's
21-second cycle time offers fast and reliable installation of the piston rings
for even the largest diesel pistons.
The gantry or articulated robot that positions the piston and is standard on
every machine offers a graphic user interface to operate the system.
The system is the newest evolution of City Machineís time-tested semi-automatic
and automatic piston ring assembly machines.
Established in 1935, City Machine Tool and Die has grown into a global supplier
of manufacturing systems. With unique mechanical and electrical engineering capabilities,
City Machine designs and builds manufacturing solutions that span world-class
special machines, fixture programs, production parts and engineering.
