The Compensator, a remote center of compliance (RCC) device that is designed to correct alignment errors with peg-in-hole automated assembly applications, is available from ATI Industrial Automation. The device features shear pads that are stiff axially and compliant laterally to allow automated assembly machines to automatically correct for lateral rotational misalignment, redacting contact force and virtually eliminating galling and jamming, the company says. The center-of-compliance device provides rapid insertion correction allowing high speed automated machines to increase productivity and minimize scrap, downtime and machine damage caused by conventional methods.

The Compensator, a remote center of compliance (RCC) device that is designed to correct alignment errors with peg-in-hole automated assembly applications, is available from ATI Industrial Automation. The device features shear pads that are stiff axially and compliant laterally to allow automated assembly machines to automatically correct for lateral rotational misalignment, redacting contact force and virtually eliminating galling and jamming, the company says. The center-of-compliance device provides rapid insertion correction allowing high speed automated machines to increase productivity and minimize scrap, downtime and machine damage caused by conventional methods.

The device, engineered to project a compliance center (also known as center0of-compliance), is ideally suited for automated assembly operations and has two high-strength anodized aluminum top and bottom plates connected by elastomeric shear pads and hardened alloy steel overload pins. The overload pins protect the compliant device from crashed while the oil- and coolant-resistant elastomeric shear pads provide the lateral compliance to reduce contact forces.

The product line is available in sizes with lateral stiffness ranges from 6 to 34 pound per inch and axial stiffness ranges from 2,329 to 8,300 pounds per inch. The Compensator uses variable shear pad combinations based on the model and the end-user's desired insertion force and compensator strength. Additional options include pneumatic lock-up that reduces vibration caused by inertia, thereby protecting the shear pads and decreasing cycle time; and lock sensing that monitors the "locked" condition of the device.
