ELECTRONIC TORQUE WRENCH EQUIPPED WITH AUTOMATIC OUTPUT-TORQUE COMPENSATION DEVICE |
摘要 |
An electronic torque wrench equipped with an automatic output-torque compensation device comprises an electronic torque wrench and replaceable wrench heads selectively installed in the electronic torque wrench. A torque-compensation setting module sets a length parameter corresponding to the specification of the wrench head. An allowable torque range conversion module and a torque-compensation conversion module respectively undertake conversions and compensations to update an allowable torque range of the electronic torque wrench and make a displayed torque equal to the torque actually output in operation. A display element presents the displayed torque and the updated allowable torque range. The user can directly learn the actually-output torque and the updated allowable torque range from the display element in realtime, neither looking up tables nor undertaking computations.;The present invention can increase convenience and reliability in usage and prevent from that excessive force damages the electronic torque wrench and insufficient force undertightens screws. |
