Product Description
The Compensator Remote Center Compliance (RCC) device
allows an assembly machine to compensate for positioning errors due to machine
inaccuracy, vibration or tolerance, thereby lowering contact forces and
avoiding part and tool damage.
When the remote compliance center is near the contact
point, the part will align with the hole automatically; correcting lateral and
rotational misalignment. The Compensator is a mechanical device that uses
high-quality elastomer shear pads to control the compliance.
RCC:
Remote Compliance Center.
Any
compliance structure has a center of compliance. If you were
to push at this center you would have a pure lateral motion (no
rotation). If you were to rotate this center, you would have
rotation with no lateral motion. A remote compliance center is
a compliance center projected outward from the device. Remote
compliance centers decouple lateral and angular motion. A RCC
device can be used in assembly to ease the insertion force.
When a project compliance center is near the insertion point of
a peg-in-hole type assembly, the peg translates into the hole
when it strikes the outside lead-in chamfer without rotating. This translation without rotation prevents the jamming and
galling seen from compliance devices that have a compliance
center far away from the insertion point. See our
Glossary for other
robotic terms.
Benefits
-
Reduce scrap, downtime, machine damage.
-
Eliminates jamming, wedging, galling.
-
Increases automatic assembly productivity (faster
throughput).
-
Lowers machine and part cost due to relaxed
tolerances.
-
Replaces centering sleeves, springs, two-stage RCCs.
-
Makes impossible assemblies possible.
Features
-
Low lateral stiffness reduces insertion force.
-
Three overload pins made of tool steel; twice the
strength of carbon steel.
-
Variety of oil-and coolant-resistant high quality
elastomer shear pads (neoprene and nitrile).
-
Single-stage design lowers cost.
-
Optional pneumatic Lock-up allows you to remove the
compliance when not needed thereby decreasing your cycle time and increasing
shear life.
