Electronic torque wrench

摘要

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.

主权项

1. A driving tool comprising:
a) a body; b) a shaft extending from the body and engageable with a fastener; c) an electronics unit insertable within the body and operably connected to the shaft, the electronics unit operable to measure an operating parameter of the shaft relative to a fastener driven by the tool and including a circuit board and a power source; and d) a barrier positioned around the electronics unit to isolate the electronics unit from an exterior environment of the tool to enable the electronics unit to be subjected to sterilizing environments when inserted within the body or separate from the body without causing damage to the electronics unit.
