AI Technical Summary

Technical Problem

Fastening tools often lead to over-tightening or under-tightening of fasteners due to the inability to accurately control torque, resulting in potential damage to fasteners or improperly assembled objects, as operators may not receive timely feedback on reaching the desired torque levels.

Method used

A wireless clutch sensor system integrated into a fastening tool that includes a clutch disengaging at a predetermined torque value, generating a completion signal to notify operators through a wireless control box, ensuring proper tightening and preventing damage or improper assembly.

Benefits of technology

The system effectively limits torque application and provides real-time feedback to operators, reducing the risk of fastener damage and ensuring proper assembly by alerting when the desired torque is reached, thus enhancing the reliability and safety of the fastening process.

Abstract

An output unit for transmitting torque from a fastening tool may include an output spindle which may be configured to operably couple with a fastener, an input interface which may operably couple the output unit to the fastening tool, a drive assembly which may be operably coupled to the output spindle, a clutch which may be operably coupled to the drive assembly and to the input interface, a clutch sensor which may be configured to detect disengagement of the clutch and may generate a disengagement signal responsive to detecting the disengagement of the clutch, a control circuit which may be configured to receive the disengagement signal from the clutch sensor and may generate a completion signal responsive thereto, and a communications module which may be configured to transmit the completion signal to a wireless control box. The clutch may disengage responsive to reaching a predetermined torque value.
