Abstract
An electro-mechanical impacting device (10) for testing the bonding of foam insulation (22) to metal (26). The device lightly impacts foam insulation (22) attached to metal (26) to determine whether the insulation (22) is properly bonded to the metal (26) and to determine the quality of the bond. A force measuring device, preferably a load cell (12) mounted on the impacting device, measures the force of the impact and the duration of the time the hammer head (16) is actually in contact with the insulation (22). This information is transmitted as an electric signal (20) to other elements of the invention's associated system (not part of this invention) which are capable of conditioning the signal and evaluating it electronically in order to provide a visual display on a video screen. This allows an operator to make decisions relating to bonding and the quality of bonding. The impactor (10) is designed in the form of a handgun having a driving spring (32) which can propel a plunger (14) forward to cause a hammer head (16) to impact the insulation (22). A load cell (12) is mounted on the plunger (14). A conditioning spring (48) slows down the plunger (14) just after it impacts the insulation (22) and prevents bouncing or more than one impact. The device utilizes a trigger mechanism which provides precise adjustments, allowing fireproof operation. Two types of gauges (72 and 92) project from the front of the device to provide stability, uniformity, and accuracy to the operation of the device.
