摘要： A tool for evaluating a thread depth includes a frame having an elongate portion extending in a first direction; a first contact member coupled to the frame and reciprocable in a second direction between a baseline height and a retracted height, the baseline height being greater than the retracted height. An output device provides an output in response to the height of the first contact member. A reference member is coupled to the frame at a first distance D1 from the first contact member as measured in the first direction; and a second contact member coupled to the frame is disposed at a second distance D2 from the first contact member as measured in the first direction, such that D1 is greater than D2.

摘要： An automatic nut internal thread quality tester is provided. The automatic nut internal thread quality tester includes a blanking module, a clamping module, a push rod module, a thread gauge driving module, and an axial pushing module. The blanking module is configured to control the nuts to be tested be blanked in series. The clamping module is configured to clamp the to-be-tested nut. The push rod module is configured to push the to-be-tested nut into the clamping module and restrict the blanking. A thread gauge of the thread gauge driving module is driven by a motor to detect the to-be-tested nut. When a torque measured by a torque sensor is greater than a threshold value, the motor reverses the thread gauge and the axial pushing module drives the clamping module away from the thread gauge.

摘要： Provided is a threaded-hole inspection device having high inspection precision. An incomplete thread ridge portion of a gauge portion 5 of a thread gauge 1 is removed, a phase-positioning portion 8 for positioning a tip-side start point 7 of a complete thread ridge at a prescribed phase when the thread gauge 1 is mounted on a rotating-shaft portion 2 is provided to a fastening portion 6 of the thread gauge 1 that is to be fastened to the rotating-shaft portion 2, and a phase-positioning engaging portion 9 that is to engage with the phase-positioning portion 8 is provided to the rotating-shaft portion 2. A depth of a threaded hole 4 to be inspected is measured on the basis of a number of rotations and thread pitch of a rotating-shaft-feeding mechanism 18 that, via threaded engagement, feeds the rotating-shaft portion 2 in a threaded-hole-approaching direction, which is a direction of approach toward the threaded hole 4, the rotating-shaft portion 2 being caused to rotate by a rotary drive portion 3, and on the basis of a distance over which an outward-moving portion 23 moves outward from the threaded hole, and the depth of the threaded hole 4 is calculated.

摘要： A method of quantifying stem nut thread wear in a valve having a valve stem that is positioned with a stem nut. A tool is mounted to, and rotates with, the stem nut, while simultaneously measuring stem displacement. The method of orienting the stem nut threads where one 360° rotation will capture all of the thread backlash in addition to any stem displacement. The measured stem displacement, including stem nut thread backlash, can then be used, with certain stem geometry parameters, to calculate stem nut thread wear percent and quantify remaining stem nut thread material.

摘要： A thread gauge inspection apparatus includes a receiving member to hold a reference thread gauge and a motor to bi-directionally rotate the reference thread gauge. A counter counts a number of turns the reference thread gauge is rotated by the motor, and a torque monitoring device monitors the torque produced by the motor as the reference thread gauge is rotated. A controller, when the monitored torque exceeds a predetermined value, causes the motor to stop rotating the reference thread gauge and causes the counter to stop counting the number of turns the reference thread gauge is rotated. The controller compares the count produced by the counter with an inputted specific turn count and indicates the thread quality of threaded hole or a threaded stud passed inspection when the count produced by the counter is equal to the inputted specific turn count.

摘要： A magnet held in a magnet holder is constrained against radial or axial instability, or against both, by a shape on either component in contact with complementary shape on the other component, the shaped components generally defining a tab-and-slot arrangement. The magnet component may be a bonded magnet and in one embodiment may be formed in place by injection molding. The magnet also will exhibit improved magnet properties when magnetized to have lines of polarity matching a path defined by the bulk of the magnetic material as governed by the location of tabs on the magnet. The invention is useful in magnet-sensor assemblies found in industrial applications and in automotive applications such as power steering systems.
