Abstract

An electromechanical wrench has a housing that has a working end and a gripping end, with a driver positioned at the working end, and a handle positioned at the gripping end. The wrench further includes a click wrench emulator mechanism provided at the handle. A method of using an electromechanical wrench to secure a fastener using angular measurement without the need for establishing a zero reference point, and allowing for ratcheting, is also provided. A method of counting the number of fasteners secured by an electromechanical wrench during a wrenching job is further provided.

IPC Classes  ?

• B25B 23/144 - Arrangement of torque limiters or torque indicators in wrenches or screwdrivers specially adapted for hand operated wrenches or screwdrivers wherein the work-contacting component pivots or rotates relative to the handle when a selected torque is exceeded having an electrical device activated by the pivotal or rotational movement which emits a signal when the selected torque is exceeded
• B25B 23/159 - Arrangement of torque limiters or torque indicators in wrenches or screwdrivers the work-contacting component comprising or being connected to a resilient structural member, which remains rigid and fully force transmitting until a selected torque is exceeded or which signals excessive torque
