Drive tool i.e. impulse drive tool, for driving e.g. nail, has tappet executing stroke movements per rotation via return spring and acting in impulse compensated manner, during simultaneous angular acceleration of rotating mass

摘要

The tool has an electrical operated balance wheel drive actuated via a switch. Two electrical driven upper and lower cam disks (2a, 2b) are rotated in opposite directions for producing impulse-type forces in a striking mechanism. The disks displace a tappet (14) in movement. The tappet executes number of stroke movements per rotation via a return spring (10) and acts in an impulse compensated manner, during simultaneous angular acceleration of rotating mass. A drive motor (4) is utilized for driving the tool.
