Embodiment Construction
[0042] exist figure 1 10 denotes a triggering mechanism according to the invention of a torque tool 12 for tightening threaded fasteners or the like with a target torque. Torque Tool 12 in figure 1 The center is shown in section as an axial longitudinal section. The torque tool 12 comprises a cylindrical base body 14 with a housing-shaped drive body 16 . A drive handle 20 is fastened in the region 18 of the drive body 16 . The driving handle 20 is firmly connected with the driving body. The drive handle 20 can be configured, for example, as a torsion bar, at which strain gauges are arranged for sensing the torque to be transmitted.
[0043] A lifting magnet 24 as an electric actuator is arranged in the cavity 22 of the drive body 16 . The lifting magnet 24 has a screw 26 . When the lifting magnet 24 is actuated, the screw 26 acts on a lever arrangement 28 of a locking mechanism 30 which is arranged between the base body 14 and the drive body 16 . The locking mechanism 3...

Abstract
The invention relates to a triggering mechanism (10, 110, 210, 310, 410) of an electronic triggering torque tool (12, 112, 212, 312, 412) for tightening threaded fasteners or the like, triggered at a target torque. A trigger mechanism (10, 110, 210, 310, 410) comprises a drive body (16, 118, 218, 318, 418) and a base body (14, 114, 214, 314, 420), which rotate about a common axis for torque transmission. In this case, the locking mechanism ( 30 , 150 , 219 , 320 , 414 ) couples the drive body ( 16 , 118 , 218 , 318 , 418 ) and the base body ( 14 , 114 , 214 , 314 , 420 ) to one another for torque transmission. Sensing and evaluating means are provided for sensing and evaluating the transmitted torque, wherein the signal generator operates the locking mechanism (30, 150, 219, 320, 414) in case the target torque is reached in order to connect the driving body (16, 118, 218, 318, 418) with the base body (14, 114, 214, 314, 420) Decoupling.
Description
technical field [0001] The invention relates to a triggering mechanism (Auslöse mechanism, sometimes called a release mechanism) of an electronic triggering torque tool (Drehmomentwerkzeug) for tightening threaded fasteners or the like, which is triggered in the case of a theoretical torque, comprising [0002] a) a drive body (Antriebskörper) and a base body (Grundkörper), which rotate around a common axis for torque transmission, [0003] b) locking mechanism (Verriegelungsmechanismus), which couples the drive body and the base body to each other for torque transmission, [0004] c) sensing and evaluation means for sensing and evaluating the transmitted torque, [0005] d) Signal generator, which actuates the locking mechanism for decoupling the drive body from the base body when the target torque is reached. Background technique [0006] Screw joints are the most commonly used connections in machine building. Such connecting elements can only be made effective by using...
