MULTISTAGE SOLENOID FASTENING TOOL WITH DECREASED ENERGY CONSUMPTION AND INCREASED DRIVING FORCE |
摘要 |
<p>A fastening device that drives one or more fasteners into a workpiece generally includes a tool housing and a multistage solenoid contained in the tool housing. The multistage solenoid includes an armature member that travels through at least a first stage, a second stage, and a sense coil disposed therebetween. A driver blade assembly includes a blade member connected to the armature member. The driver blade assembly is operable between an extended condition and a retracted condition. A control module determines a position of the armature member relative to at least one of the first stage and the second stage based on a signal from the sense coil. The trigger assembly is connected to the control module and partially contained within the housing. The trigger assembly is operable to activate a driver sequence that moves the driver blade between the retracted condition and the extended condition. The control module adjusts a force imparted on the armature by at least one of the first stage, the second stage, and a combination thereof based on the signal from the sense coil.</p> |
