Title:
RELEASE MECHANISM FOR A TORQUE TOOL
Document Type and Number:
WIPO Patent Application WO/2019/137577
Kind Code:
A1
Abstract:
The invention relates to a release mechanism (10, 110, 210, 310, 410) for an electronically releasing torque tool (12, 112, 212, 312, 412) for tightening a screw or the like, which is released in the event of a target torque. The release mechanism (10, 110, 210, 310, 410) contains a drive element (16, 118, 218, 318, 418) and a main part (14, 114, 214, 314, 420), which rotate about a common axis in order to transmit a torque. A locking mechanism (30, 150, 219, 220, 414) couples the drive element (16, 118, 218, 318, 418) and the main part (14, 114, 214, 314, 420) together in order to transmit a torque. Detection and analysis means are provided for detecting and analyzing the transmitted torque, wherein a signal transmitter actuates the locking mechanism (30, 150, 219, 320, 414) in order to uncouple the drive element (16, 118, 218, 318, 418) from the main part (14, 114, 214, 314, 420) when a target torque is reached.
