Abstract
An armlike driving mechanism includes a power source connected to a screw rod and a nut, a driving assembly including a first gear, a second gear, and a drive belt, a rail assembly including a linear rail and a sliding element, and a connecting block fixed on the drive belt and linked to the nut and the sliding element. The power source drives the screw rod and the nut by back and forth rotation, thereby displacing the sliding element in an X axle direction and driving the first gear in an Y axle direction by the connecting block and the drive belt, so as to operate the armlike driving mechanism.
Claims6
An armlike driving mechanism, comprising:
- a housing having a space therein and a joint section made of a pair of installation holes arranged at a rear end thereof;
- a power source disposed at an upper section at a side in the space and engaged a screw rod, said screw rod having a nut screwing through with a same pitch as the screw rod;
- a driving assembly including a first gear, a second gear, and a drive belt, said first gear and second gear being respectively installed on a first pivot and a second pivot and said drive belt surrounding along the first and second gears for rolling;
- a rail assembly fixedly disposed at a lower section in the space, including a linear rail and a sliding element to displace along the linear rail;
- a connecting block fixed on the drive belt, having a top thereof fixedly linked to the nut and a bottom thereof fixedly linked to the sliding element;
- whereby the power source drives the screw rod to rotate back and forth to drive the nut, displacing the sliding element along an X axle and driving the drive belt to control a radial displacement of the first gear, so as to operate the armlike driving mechanism.
