A ROTARY TO RECIPROCATING MOTION CONVERSION ATTACHMENT FOR A POWER ROTARY HAND TOOL |
摘要 |
A preferred embodiment of a rotary tool reciprocating motion conversion attachment for a rotary power hand tool is described which is configured to be attached to a nose portion of the hand tool housing. The attachment has a rotary drive train (60) in a housing (12) that is connectable to the output shaft of the hand tool, the drive train driving a barrel cam having an exterior cam groove (134). A cam follower rides in the cam groove and produces reciprocating motion, with the cam follower being part of a cam follower assembly to which an implement holder is attached. The preferred embodiment has a cam groove configuration which causes the implement holder to move slower during a cutting stroke and faster during a return stroke, thereby tending to optimize the operation of the cutting implement. The preferred embodiment also includes a planetary gear set for reducing the rotational speed of the hand tool output shaft to reduce the speed of reciprocation of the attachment.
