The invention discloses a
friction torque adjustable
robot joint and a using method, and belongs to the field of robots, a plurality of
robot joints can be combined for use, and each
robot joint is structurally characterized in that a rotating shaft is placed in a
barrel-shaped cavity of a pressure loading structure; positioning bolts are placed on the end surfaces of the rotating shafts; the
lower limb connecting device is of a U-like integrated structure, is connected with the rotating shaft through a positioning bolt, and is matched with a fastening screw for installation; the
upper limb connecting clamping head is of a U-like integrated structure and is installed in cooperation with the pressure loading structure, the
gasket, the
saddle-shaped spring and the pre-tightening force adjusting bolt.
Robot joints can be independently mounted to realize a one-way adjusting function; angle adjustment in two directions can be achieved through combined installation of the
upper limb connecting clamping head. Coordination and unification of position keeping stability and posture adjusting smoothness can be achieved, the risk of joint failure caused by serious abrasion possibly caused by large
friction force is reduced, a self-lubricating
polymer material with good abrasion resistance is introduced to serve as the rotating shaft, and the performance degradation rate of the joint after long-term repeated use is reduced.
