Preset electronic torque tool

摘要

An electronic torque wrench or other tool, and a method and a computer program for using the same, are disclosed. The disclosed systems allow a user to operate the tool in either a manual mode or automatic mode. In the manual mode, torque or angle targets are input into the wrench before the torqueing operation, and in the automatic mode, preset torque or angle targets are selected by the user. A user can also lock the tool so only a specific torqueing operation can be used without unlocking the tool. The torque and angle values can be input simultaneously such that a work piece can be torqued to a predetermined torque and angle without separate operations. An indicator can also be implemented that indicates the progress of the torqueing operation.

主权项

1. A tool adapted to apply a torque to a work piece, comprising:
a head adapted to transmit the torque to the work piece; a sensor operably coupled to the head and adapted to sense an amount of the torque applied to the work piece; an interface adapted to receive an amount of tolerance and a target value representing a desired amount of the torque to be applied to the work piece; and an indicator adapted to provide a first indication when the amount of torque applied to the work piece is a first predetermined percentage of the target value, minus the amount of tolerance, and a second indication when the amount of torque applied to the work piece is a second predetermined percentage of the target value, plus the amount of tolerance.
