The utility model provides a kind of positioning control structure of drive joint convenient to control, the utility model relates to industrial machinery technical field, including joint seat and positioning disc, joint seat and positioning disc are the matching
pipe base of symmetrical arrangement, joint shaft is inserted between joint seat and positioning disc as drive joint part;The utility model has the beneficial effect that: through the joint structure of
external connection butt joint to adapt joint movable end, its structure utilizes the axial
brake structure set to carry out joint movable
brake to external motor, and there is the core shaft that tooth disc corner displacement is matched in its
brake structure, cooperation angle displacement sensor is used to real-time acquisition angle displacement data, to realize the adjustment to joint movable position according to the feedback of angle displacement data when joint movable, and can be combined with the axial locking structure of
pneumatics to complete the locking to joint movable angle, realize the real-time positioning control to joint.
