The invention discloses a trunk simulation mechanical arm. The trunk simulation mechanical arm comprises a base bracket, a ball screw pair, a mechanical arm and a gripper; the ball screw pair drives the mechanical arm to move up and down; the base bracket drives the ball screw pair to drive the mechanical arm to rotate; the mechanical arm includes three joints for controlling the mechanical arm to rotate up and down, and three joints for controlling the mechanical arm to rotate left and right; and a stepper motor is mounted in a base for driving a disc to rotate so as to realize a peripheral motion of the mechanical arm to work in all directions. As a large nut is fixed without rotating, the ball screw pair only can move up and down along a lead screw to drive the mechanical arm fixed on a vertical patch to move up and down so as to widen the space control range of the mechanical arm. The gripper is provided with three jaw teeth for freely extending; and plastic gaskets are mounted at the tips of the jaw teeth for increasing the friction force, so that the object grabbing is more stable.
Description
technical field [0001] The invention belongs to the technical field of mechanical design and manufacture, in particular to a mechanical arm imitating an elephant trunk. Background technique [0002] With the development of society, in the rapidly developing automation industry, industrial production has more and more requirements for the bionic technology of robotic arms. The generation of the mechanical arm can not only replace the heavy and monotonous labor of people, but also work in places with dangerous or harmful gases, which greatly improves the work efficiency. In recent decades, robotic arm bionic technology, as a high-end automated production technology, has developed rapidly both at home and abroad. The robotic arm can be programmed to perform circuit control and operate freely like an arm to achieve the purpose of grasping. However, at this stage, the research on the manipulator is not deep enough, so that the manipulator cannot be used as flexibly as the human...
