Abstract
This utility model relates to the field of surgical robot technology, and discloses a robotic arm and a surgical robot. The robotic arm includes a rotating shaft, a linkage assembly, and a balancing assembly. The rotating shaft extends along a first direction, and a connector is fixedly provided on one side of the rotating shaft; the linkage assembly is rotatably connected to the rotating shaft, and a guide wheel is provided on the linkage assembly, with the guide wheel located between the center of mass of the rotating shaft and the linkage assembly; the balancing assembly includes a spring and a pull rope, with one end of the spring fixedly connected to the linkage assembly and the other end connected to the connector via the pull rope. During the rotation of the linkage assembly within a preset angle range, the first segment of the pull rope located between the guide wheel and the center of mass is collinear with the vertical connecting line. The spring's stiffness coefficient allows the spring force relative to the rotating shaft to generate a balancing torque that can balance the gravitational torque that the linkage assembly needs to balance, improving the operator's operating comfort and simplifying the robotic arm assembly process.
