Electronic torque wrench
A torque wrench for use in driving fasteners is provided. The wrench includes an electronics unit disposed within a housing engaged with the 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 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 housing for the electronics unit can be formed to be a single use component of the tool or can be designed for multiple uses with a configuration that can be engaged with cradles forming the body of the wrench having various different configurations.
1. A driving tool comprising:
a body capable of being subjected to temperatures and pressures associated with medical sterilization procedures;
b) a shaft operably connected to the body and engageable with a fastener;
c) a housing including an electronics unit including a torque measurement system operably connected to the shaft and operable to measure the torque exerted though the shaft on a fastener, wherein the housing is capable of being subjected to temperatures and pressures associated with medical sterilization procedures without damage to the electronics unit.
2. The tool of claim 1 wherein the housing is disposed within the body.
3. The tool of claim 1 wherein the housing is separable from the body.
4. The tool of claim 3 wherein the housing is connected to the body by a locking mechanism.
5. The tool of claim 3 further comprising a lock-out switch disposed on the body and able to be deactivated by a complementary structure on the housing.
6. The tool of claim 1 further comprising a control unit operably connected to the electronics unit.
7. The tool of claim 6 wherein the control unit is wirelessly connected to the electronics unit.
8. The tool of claim 1 further comprising an electronic memory component operably connected to the electronics unit.
9. The tool of claim 8 wherein the electronic memory unit is disposed within the housing.
10. The tool of claim 1 further comprising a display operably connected to the electronics unit for displaying the torque measurement values determined by the torque measurement system.
11. The tool of claim 10 wherein the display is located on the body.
12. The tool of claim 10 wherein the display is located on the housing.
13. The tool of claim 10 wherein the display is spaced from the body and the housing.
14. A method of driving a fastener into a substrate comprising the steps of:
a) providing the tool of claim 1 ; and
b) engaging a fastener with the tool.
15. A driving tool comprising:
a) a body capable of being subjected to temperatures and pressures associated with medical sterilization procedures:
b) a shad operably connected to the body and engageable with a fastener:
c) a housing including an electronics unit including a torque measurement system operably connected to the shaft and operable to measure the torque exerted though the shaft on a fastener; and
d) a power source operably connected to the electronics unit, wherein the power source is positioned within the housing.
16. The tool of claim 15 wherein the power source is wirelessly chargeable.
17. The tool of claim 15 wherein the power source is separable from the housing.
18. The tool of claim 17 wherein the body and the housing are capable of being subjected to temperatures and pressures associated with medical sterilization procedures without damage to the electronics unit.
