Abstract
A method, system and device for determining the quality of assembly of tool parts involves measurement of the rates of rotation of the tool parts or the torque imposed on the tool parts, or a combination thereof, followed by measurement of axial strain, or torsional strain, or hoop strain, or a combination thereof. The measured data are processed to determine the presence of a shoulder, seizing, seals, extreme hoop pressure, mismatched connections, and the like during assembly of the tool parts, thus assuring quality of assembly. The collected data are plotted versus time and displayed for the operator. The clamping device employed can be a one-part device for measuring hoop strain only, or can be a two-part device for measuring two or more of the aforementioned strain values.
