The invention discloses a grabbing and lifting
adaptation robot arm and belongs to the technical field of
robot arms. The grabbing and lifting
adaptation robot arm comprises a worm, a worm wheel, a roller, an end opening cover, fixed pulleys, a
steel rope, springs I, a base, a base disc I, a fixing support, a base disc II, clamping rods, a lifting hook, springs II, springs III and a traction
rope. The grabbing and lifting
adaptation robot arm is used by a robot for grabbing objects, a self-adaptation grabbing function not limited to object shapes is achieved, the multiple grabbing rods are used for obtaining the self-adaptation effect on the object sizes and shapes, the worm wheel and the worm are driven to tightly pull the traction
rope through the lifting hook,
extrusion force obtained in the manner that the multiple clamping rods are gathered towards the center is achieved, a multidirectional grabbing effect on the objects is achieved, the lifting hook can also be directly used for lifting the objects, the structure is simple,
energy consumption is low, grabbing or lifting is fast, reliability is good, the service life is long, and under the assistance of the unidirectional drive of the worm wheel and the worm, grabbing is stable and safety is high.
