Abstract: An adaptor tool for mounting components on printed circuit boards. The adaptor tool has two capture members that define an opening sized to receive the component. The capture members are linked together such that the application of torque to the adaptor tool by a torque tool via a connector results in the two capture members frictionally engaging the component and transferring the torque to the component. This allows the component to be mounted to the printed circuit board to a desired degree of torque. The adaptor tool can be sized so as to be able to mount a cylindrical heat sink to a bracket on a printed circuit board to a desired degree of torque.

Abstract: The invention is a method and apparatus for continuously monitoring the application of a coupling to a pipe. The invention operates in several modes. In the position mode, the apparatus rotates the coupling to a desired final position. In the program mode, the apparatus determines the actual location of the hand-tight plane and continuously monitors the torque applied and the number of turns of rotation of the coupling from the hand-tight plane to the desired final position. In either of these modes, the torque applied is monitored and rotation of the coupling is discontinued if a preset maximum torque value is exceeded. If the coupling is rotated to the desired final position without reaching a minimum torque, the pipe and coupling are rejected. An image processing system is employed to locate several critical make-up parameters.

The engaging head of the feed rod is then advanced, and substantially at the same time as the engaging head engages the threaded part the holding member is moved backward to allow the feed rod to be advanced. Thus, the threaded part is fed to a mating part, such as a threaded hole or a bolt, and tightened.

Abstract: An apparatus for tightening threaded fasteners to any desired proportion of the way through a torque-angle specification window defined by low and high angle limits and low and high torque limits. The torque rate for the joint is determined from torque and angle measurements taken during tightening and compared to boundary ratios which are determined as the rates of change of torque with respect to angle from a threshold torque to the corners of the specification window. A final target parameter value of either torque or angle is calculated based upon this comparison which is approximately halfway through the specification window along a projection of a torque-angle characteristic curve for the fastener which is determined from the torque rate. Correction factors are also provided for tool overrun depending upon whether torque or angle control is used and a reject rate margin is employed to account for nonlinearities which otherwise may lead to unacceptable assemblies.

Abstract: Make-up of a pipe section and coupling to form a tubular joint having proper stand-off at proper make-up torque is automatically controlled. The coupling is first rotated onto the pipe section to a hand-tight position and the length of the coupling and the distance from the open end of the coupling to the pin end of the pipe section are measured by a digital measuring device which inputs these measurements to a computer. The number of turns of the coupler required to attain optimum stand-off is calculated by the computer. The pipe section is held stationary and power tongs rotate the coupling further onto the pipe section while the applied torque and the number of turns are measured and provided as inputs to the computer. The computer determines that the made up tubular joint is acceptable or not acceptable during the rotation by determining if the stand-off is within a predetermined make-up stand-off range at the same time that the make-up torque is within a predetermined make-up torque range.
