The L-shaped structure of described rod member, one end of L shape structure is positioned at the grooved rail of groove cam, and the other end connects actuator.
One end of described rod member is provided with roller, and described roller is positioned at the grooved rail of groove cam.
Described rod member is set on the axle that play supporting role, and the two ends of axle are carried out spacing.
Described rod member connects actuator by connecting rod, and Rod end arranges sliding eye, and one end of connecting rod is positioned at sliding eye, and the other end connects actuator.
Described actuator comprises the slide block hinged with connecting rod one end, and slide block is arranged in the chute that matches.
Compared with prior art, the utility model is rotated by motor driver slot cam, the grooved rail of groove cam is irregular shape, one end of rod member is positioned at grooved rail, groove cam rotates and rod member will be driven to turn round, rod member connects actuator, drive in actuator's vertical plane and move up and down, when rod member moves to the far-end of grooved rail, drive actuator accelerated to move upward, when moving to the near-end of grooved rail, actuator will speed up and moves downward, when moving to position equidistant in grooved rail, by actuator's transfixion.Along with rod member move in irregular grooved rail time, reach and the speed of actuator is changed and obtains the object of different stroke, the utility model is when motor outputting power is constant, as long as change the grooved rail geomery of groove cam, the speed that can be wanted arbitrarily and stroke, convenient motion speed and the stroke changing actuator, and operate steadily, structure is simple.
Further, motor by large small pulley and belt by power transmission to rotating shaft, power transmission is steadily reliable, and structure is simple.
Further, groove cam is installed in disk, drives groove cam to rotate, can realize power transmission reliably, and avoid groove cam and directly contact with rotating shaft, improve the working life of groove cam, further increase the stability of whole device by disk.
Further, rod member is L shape structure, and L shape structure one end arranges roller, and roller is positioned at the grooved rail of groove cam, utilizes idler wheel driving lever part to turn round, can transmit power more reposefully.
