Abstract

The invention discloses a double-screw rod rope driving structure. The double-screw rod rope driving structure comprises a rope, an output end plate, a side plate I, a screw rod I, a sliding block, a screw rod nut I, pulleys, an input end plate, a gearbox, a direct current motor, a screw rod II, a side plate II and a screw rod nut II, wherein the output end plate and the input end plate are connected through the side plate I and the side plate II; an output shaft of the motor is in transmission connection with the screw rod I and the screw rod II through the gearbox; the screw rod nut I and the screw rod nut II are fixed on the sliding block; the initial end of the rope is fixed on the sliding block; the screw rods push the sliding block to do linear motion; the sliding block drags the initial end of the rope, so that the rope generates relatively high motion precision; under the driving of the double screw rods, the rope can generate relatively high tension; and the pulleys mounted on the two sides of the sliding block are matched with tracks of the left side plate and the right side plate, so that the sliding block is prevented from rolling over, and the motion stability of the initial end of the rope is improved.

Description

technical field [0001] The invention relates to the field of rope-driven robots, in particular to a double-screw-rod drive mechanism. Background technique [0002] In the field of transmission, the rope can be used as a transmission medium to realize long-distance and low-vibration transmission in the motion mechanism, which can not only transmit line displacement, angular displacement, but also transmit force. The rope drive mechanism does not need lubrication during the movement process, the impact is small, and it is easy to realize smooth movement. At present, the rope drive has been applied to the field of manipulators and robot grippers. The use of rope drive greatly reduces the joint weight of the manipulator or robot gripper, and reduces the maintenance cost at the same time. [0003] The screw drive has the characteristics of high precision and stable operation, and is very suitable for mechanisms that do not require high speed but high transmission precision. [...
