A torque wrench for use in driving fasteners is provided. The wrench includes an electronics unit disposed within a body of the wrench that is capable of sensing and measuring the torque applied to a fastener by the wrench and providing an output of the level of torque to the user. The electronics unit is also disposed within a barrier in the body that isolates the unit from the exterior environment around the wrench. The data sensed by the electronics unit can be utilized to provide feedback to the user regarding the operation of the wrench, and to monitor the overall operation of the wrench for calibration purposes, among other functions. During use, the wrench can provide the user with visual, audible and tactile feedback regarding the operation of the device relative to stored maximum torque values stored in the electronics unit.

The system also includes a camera configured to capture an image of the workpiece when an appropriate amount of torque has been applied to the fastener. The system further includes a microprocessor for determining sequence of the fastener and identifying the tightened fastener.

The present invention provides a device for confirming that threaded fasteners have been tightened to the level of torque required by the assembly specification. An apparatus and method is provided for validating or verifying a fastener connection. A wrench or other torque tool can be engaged with a fastener to be tested. A rotation sensor is associated with the wrench for sensing rotation of the fastener and for generating a first output signal. A torque sensor is associated with the wrench for generating a second output signal corresponding to torque being generated by the wrench against the fastener. A processor is in communication with the rotation sensor to receive the first output signal and is in communication with the torque sensor to receive the second output signal. The processor analyzes the first and second output signals in accordance with a control program stored in memory.

Disclosed herein is a variable speed tool useful for use with securing or removing industrial fasteners. The tool also includes a means to torque the fastener to a certain precise torque. The tool can be used with an associated controller that provides control commands to the tool.

A radio identification enabled wrench system is disclosed. The system includes a template having multiple RFID tags. The template also corresponds to a part associated with a particular fastener that is associated with each of the multiple RFID tags. The system further includes a torque wrench having a RFID reader and a RFID antenna and a means for identifying what fastener the wrench is being used upon and whether the correct torque has been applied to the fastener and configured to provide a feedback for a user. The system includes a means for transferring data that may be either wired or wireless.

A torque wrench is provided having body and a handle that is rotatably mounted to the body for adjusting the torque setting, and an axially movable sleeve operable to selectively lock the handle. The sleeve includes a rigid member and an elastomeric member, such as an O-ring, and the sleeve is configured to act against a locking ball held in a bore of the handle. The sleeve is selectively movable between two positions: (a) a locked position wherein the rigid member firmly retains the locking ball seated in one of several detents in the body, thereby preventing rotation of the handle; and (b) an unlocked position wherein the elastomeric member biases the locking ball inwardly, deflecting when the locking ball unseats from the detent to permit handle rotation. When the sleeve is in the unlocked position, the locking ball can incrementally “click” over the detents during handle rotation.

A mobile vacuum boring and mud recovery method comprising a device which will create a vacuum condition within a vacuum container and the vacuum container is mounted on an incline to provide space beneath it to locate a water storage container, and having a vacuum conduit to transport a liquid and or solid particles into the vacuum container. The inclined vacuum tank facilitates gravitational assistance in both separation of liquids & solids as well as unloading debris. A dispensing device may be added to dispense a liquid or a solid from the vacuum container without eliminating the vacuum environment within the vacuum container, and said vacuum container having the ability to fill, store and dispense its contents simultaneously. The vacuum container may further comprises a means to separate a liquid from solids. The vacuum conduit articulated boom used to transport debris into the vacuum container may have the added feature or attachments chosen from an earth digging bucket, a telescoping vacuum conduit, sensor to locate buried utilities, monitors and controls to operate the attachments an their function, water spray nozzle, man hole cover remover cutting tool grinding tool, saw, blasting tool, surface cleaning tool, demolition tool, torque wrench, tractor to pull vacuum hose, jetter nozzle, or camera and power source to operate them. The above described vacuum system may be mounted on a variety of mobile platforms, chosen from but not limited to a trailer, truck, skid steer, fork lift, track hoe, railroad car, or zero turn radius vehicle which may have the added feature of being convertible between a powered vehicle & a trailer.

A torque wrench includes a pressure handle, a sheath end, a directional brake module, an overload movement ring, rolling rods, rolling beads and spring bolsters. The overload movement ring is provided between the brake section of directional brake module and the assembly groove of sheath end. The interior of the overload movement ring is designed with a circular tooth rim for the articulation/brake of the brake section of directional brake module, whereas the exterior is designed with a polygon. Moreover, a containment groove is provided at the intersection of various surfaces to accommodate the rolling rod and rolling bead, thus the outer flank of various rolling rods and rolling beads will protrude the aperture of the containment groove, and then keep in close contact with the wall of the assembly groove. One surface of the overload movement ring is supported and braked by the movable shore of spring bolster.

A system includes a handheld tool for executing steps of a sequence within a work cell. An electromagnetic marker connected to the tool emits a magnetic field within the cell. A receptor detects the magnetic field and generates a raw position signal in response thereto. A control unit updates an assembly setting of the tool. The host executes a control action when a position determined using the raw data is not equal to an expected position in the sequence. A method calculates the present position of a torque wrench using magnetic fields generated by the marker and measured by a receptor array, and calculates a present position of the tool or a fastener. The present position of the fastener may be compared to an expected position in the calibrated sequence, and the torque wrench may be disabled when the fastener position is not equal to the expected position.
