A three-plane-
branch six-degree-of-freedom parallel wall-climbing
robot mainly comprises a movable platform, a
laser gun, three plane branches, a reset mechanism and three traction legs. Each plane
branch comprises two telescopic driving legs, the upper end of each driving leg and the movable platform are in composite universal pair connection through a transverse shaft, and the lower end of each driving leg and a permanent magnetic chuck are in composite ball pair connection. The traction legs can stretch out in a rigidity mode, retract in a flexibility mode and swing, the upper end of each traction leg and the movable platform are in ball pair connection, and the lower end of each traction leg and a permanent magnetic chuck are in ball pair connection. The reset mechanism enables the plane branches to be reset through the transverse shafts. Pressing springs enable the traction legs to be reset, all the legs and the permanent magnetic chucks are in
coordinated movement, and wall face climbing of magnetic workpieces is achieved. After absorbing and positioning are completed, the
absorption capacity of the chucks acts on the movable platform all the time, the wall-climbing
robot is changed into a parallel
robot, and the movable platform drives the
laser gun so that large equipment can be repaired and workpiece defects can be overcome. The three-plane-
branch six-degree-of-freedom parallel wall-climbing robot has the advantages of being simple in structure, strong in
absorption capacity, flexible to move, simple in control, low in
self weight, and capable of achieving the dual functions of quick translation
wall climbing and large-load six-degree-of-freedom flexible operation.
