Abstract
Embodiments of systems and methods for positioning and bonding a nutplate to a substrate comprising at least one aperture, wherein the system includes a nutplate retention fixture formed from a threaded insert and an elastomeric tube engaged with the threaded insert; a heater assembly formed from a heating element, a temperature sensor operable to measure the temperature of the heating element, and a heater housing; a heater retention fixture operable to engage with the nutplate retention fixture and maintain the heater assembly in contact with the substrate; and a heater controller operable to control the output from the heating element. The heater retention fixture includes a cam-lock clamp provided concentrically around the nutplate retention fixture and configured to provide a circumferential clamping force to secure the heater retention fixture to the nutplate retention fixture.
