Abstract:
1. A torque testing system for testing whether a first structure and a second structure are capable of satisfactory threaded engagement together, a desired depth of the first structure turned into the second structure being in a range from a predetermined minimum depth to a predetermined maximum depth, and a desired friction between the first structure and the second structure being in a range from a predetermined minimum friction to a predetermined maximum friction when the first structure is turned into the second structure the desired depth, the torque testing system comprising: a first screwdriver for turning the first structure into the second structure using a maximum torque equal to the predetermined maximum friction until the depth of the first structure turned into the second structure is equal to the predetermined minimum depth or the first structure is unable to be turned any more by the maximum torque; a second screwdriver for turning the first structure into the second structure using a minimum torque equal to the predetermined minimum friction until the first structure is unable to be turned any more by the minimum torque; a height measuring device for measuring the height of the combined first structure and second structure; and a processor for comparing the measured height of the combined first structure and second structure with a predetermined minimum height and a predetermined maximum height of the combined first structure and second structure, and determining that the engagement between the first structure and the second structure satisfies a threaded engagement requirement if the measured height of the combined first structure and second structure is in a range from the minimum height to the maximum height of the combined first structure and second structure.
