Abstract
A fastener driving machine, which comprises an energy storage unit; an impact unit used to drive the energy storage unit to store energy and withstand the energy released by the energy storage unit to drive fasteners into a workpiece; a driving mechanism connected to the impact unit; a rotating power mechanism connected to the driving mechanism to provide rotating power to the driving mechanism. The driving mechanism comprises a stationary annular gear, a crank connected to the rotating power mechanism, and at least one planetary gear which is connected to the crank in a spinning manner and revolves with the rotation of the crank relative to the annular gear, and an engaging shaft eccentrically connected to the planetary gear to push the impact unit. The planetary gear is placed in the annular gear to mesh with the annular gear.
Claims9
A fastener driving machine comprising:
- an energy storage unit;
- an impact unit used to drive the energy storage unit to store energy and withstand the energy released by the energy storage unit to drive a fastener into a workpiece;
- a driving mechanism, which is connected to the impact unit;
- a rotating power mechanism, which is connected to the driving mechanism to provide rotating power to the driving mechanism;
- wherein the driving mechanism comprises:
- a stationary annular gear;
- a crank connected to the rotating power mechanism;
- a planetary gear connected to the crank in a spinning manner and revolves with the rotation of the crank relative to the annular gear;
- and
- an engaging shaft fixedly connected to the planetary gear to transmit a torque between the planetary gear and the engaging shaft and to push the impact unit, wherein the engaging shaft is an extension of the planetary gear and the engaging shaft rotates together with the planetary gear, wherein the planetary gear is placed in the annular gear to mesh with the annular gear, wherein the engaging shaft rotates together with the planetary gear, wherein a trajectory of a center of the engaging shaft travels in a non-circular motion around an axis of the annular gear, and wherein disengagement of the engaging shaft from the impact unit is a function of a relative position of the engaging shaft and the impact unit as the planetary gear revolves relative to the annular gear.
