Double-cam fastener driving machine

A double-cam fastener driving machine, including

• an energy storage unit (1) comprising an air spring, a mechanical spring, a rubber element, or a vacuum device;
• an impact unit (2) comprising a piston (22) arranged in the energy storage unit (1) and a striker (21) connected to the piston (22), for actuating the energy storage unit (1) to store energy which can bear the energy released from the energy storage unit (1), so as to drive a fastener into a workpiece;
• a rotating actuating unit (3);
• a pushing mechanism (4) comprising a first pulley (41) fixed to a second output shaft (53), a cord (42) connected to the first pulley (41) and several second pulleys (43) used to guide a direction of the cord (42), connected and linked with the impact unit (2);
• a double-cam mechanism (5), including a first cam (51) and second cam (52), wherein the first cam (51) is connected to the rotating actuating unit (3) and driven by the rotating actuating unit (3) to rotate, and the second cam (52) is connected to and interlocked with the pushing mechanism (4);
• wherein the rotating actuating unit (3) includes a gear transmission module (31), a motor (32) installed in cooperation with the gear drive module (31), and a first output shaft (33) mounted on the gear transmission module (31) and used to drive the rotation of the first cam;
• wherein the first output shaft (33) is fixed with a clamp shaft (34), the first cam (51) is sleeved on the first output shaft (33) in a rotatable manner, and an arc-shaped chute (511) is provided on the first cam (51), into which one end of the clamp shaft (34) extends;
• the clamp shaft (34) including a base (341) and a cylindrical shaft body (342) formed on one side of the base (341) and perpendicular to the base (341), the base (341) is fixedly sleeved on the first output shaft (33), and the cylindrical shaft body (342) extends vertically from top to bottom into the arc-shaped chute (511).
