A calibration monitoring system is provided to automatically monitor the calibration status of tools and other inventory items, such as upon the items being issued from or returned to the automated calibration monitoring system. The system identifies an inventory item, for example a calibrated torque wrench or other calibrated tool identified based on a unique identifying tag attached thereto. The system retrieves a calibration parameter value for the item from a calibration database, and completes a calibration measurement of the item based on the calibration parameter value. In the example, a torque measurement of the calibrated torque wrench can thus be automatically completed. In turn, the system determines a current calibration status of the item based on the calibration measurement, and selectively enables or disables issuance of the inventory item from the system according to the item's status as being in calibration or out of calibration.

A threaded sleeve for assembling with heat input in a component manufactured by FDM process is provided. The threaded sleeve includes a groove along its longitudinal axis. Further, the outwardly facing surface of the threaded sleeve includes a self-tapping thread which is divided into two sections along the threaded sleeve's longitudinal axis. The first section includes a constant pitch diameter and the second area comprises a pitch diameter decreasing along its longitudinal axis. The inwardly facing surface of the threaded sleeve comprises a metric thread. Furthermore, a kit, a system and a method for assembling with heat input the above-mentioned threaded sleeve in a component manufactured by FDM process is provided.

A torque wrench (100, 400) may include a body (410), a force detector (420) operably coupled to the body and configured to detect a bending force applied to the body, and a user interface (140) operably coupled to the body and the force detector. The user interface may be configured to include a setting mode in which a variable feature of the torque wrench is adjustable. The user interface may be further configured to, when in the setting mode, adjust the variable feature based on the bending force applied to the body and detected by the force detector.

The present disclosure relates to an electronic torque tool, a calibration fixture, and a method for calibrating the electronic torque tool. The calibration includes applying a torque to the torque wrench and releasing the applied torque once the applied torque reaches a full scale calibration torque. The calibration fixture holds and displays a peak value of the applied torque and the torque wrench holds and displays a measured peak value of the applied torque. The measured peak value on the torque wrench may then be adjusted, by incrementing or decrementing the displayed value, to match the peak value displayed on the calibration fixture.

A torque wrench includes a driving device having a connecting rod pivotably connected to a body. The connecting rod is pivotably connected to a head of the driving device and is pivotable between first and second positions. The torque wrench has first and second lever arms corresponding to the first and second positions, respectively. A torque device is mounted to the body and presses against an abutting end of the connecting rod. An adjusting device is movably mounted to the body and is operatively connected to the torque device for setting an initial torque value. A measuring unit measures the initial torque value. An operating unit multiplies the initial torque value by a first or second correction coefficient corresponding to the first or second lever arm to obtain a corrected torque value. A display unit displays the corrected torque value.

An example torque wrench is provided. The example torque wrench may include a drive head configured to engage with a tool for rotating a fastener. The drive head may have a drive axis about which the drive head rotates when rotating the fastener. The torque wrench may also include a deflection member coupled to the drive head and an outer body coupled to the deflection member at a first loading point and a second loading point. The torque wrench may also include a first strain gauge coupled to the deflection member between the drive head and the first loading point, and a second strain gauge coupled to the deflection member between the first loading point and the second loading point.

A work management apparatus, method, and system enable to accurately manage position, tightening torque and other information for all fastening parts, for tightening work using a tool with a torque sensor. The system includes: a driver provided with a torque sensor; and first and second cameras that capture images of a product from different viewpoints. The torque sensor starts measurement of the tightening torque when a detected tightening torque exceeds a set threshold value, stops measurement of the tightening torque when the measurement data satisfies a predetermined condition, and outputs torque related data that includes measurement time. The system further includes: a PC that calculates coordinates of an engagement position of a bit from a plurality of image data captured by the first and the second cameras corresponding to the measurement time included in the torque related data; and a marker mounting device provided with a marker and removably mounted to the bit.

A vibrating wrench includes a housing, a driving head, a handle and a vibrating structure. The housing includes a hollow space. The driving head is disposed at one end of the housing. The handle is disposed at the other end of the housing and includes an inner wall and a containing space. The containing space is communicated with the hollow space. The vibrating structure is disposed in the containing space of the handle and includes a vibrating motor and a medium element. The medium element is fully connected or partially connected to an outer surface of the vibrating motor. The inner wall of the handle is fully connected or partially connected to the medium element.

By way of non-limiting example, the present approaches use a combination of at least a load cell sensor and a strain gauge sensor to provide near real time and real time data to a microprocessor for evaluation of the torque applied to a work piece. The microprocessor is further configured to communicate data obtained from the at least two sensors to a remote data monitoring, storage or analysis platform. In one or more implementations, the data obtained by the microprocessor from the at least two sensors include the ability to track if any adjustments are erroneously made to the torque application tool itself or if the torque application tool is configured to send an incorrect signal that corresponds to the amount of torque applied to a workpiece.

A programmable screw driver and method for affixing screws into bone is disclosed. The screw driver includes a torque sensor for measuring torsional input during screw insertion, a rotational motion sensor for measuring the rotation of the screw driver, and a microprocessor. Once a surgeon rotates a screw to be affixed to the bone, the torque sensor measures the torque and sends this information to the microprocessor. Once a predetermined torque level is attained, the microprocessor begins to measure subsequent rotation of the screw driver until a predetermined rotational limit, thereby causing a signal to be sent to alert the surgeon to stop tightening.
