Abstract
A calibration device measures the maximum pull force developed by a banding tool while tightening a metal band around a tubular sleeve, such as a termination sleeve on an electrical connector housing. The calibration device includes a strain gauge assembly carried by a frame. One portion of the frame includes a releasable jaw assembly for securely capturing the band to allow the pull force of the tool to be measured. Disposed adjacent the releasable jaw assembly is a foot portion of the frame having a slot for receiving a removable nosepiece. The removable nosepiece is formed to the contour of the nosepiece of a particular banding tool. Since the nosepiece is removable, various nosepieces having contours for various banding tools can be utilized. The calibration device also includes a force release assembly for gradually releasing the force on the force sensing element to avoid damage thereto. The force release assembly includes a lever operated cam and a cam follower which allows the force on the force sensing element to be gradually released by rotating the lever.
