Described contiguous block one end is connected with column side by fixed joint, the other end is connected with the 5th connecting rod one end by the 11 revolute pair, the 5th connecting rod other end is connected with six-bar linkage one end by the tenth revolute pair, and the six-bar linkage other end is connected with second link of principal arm by the 5th revolute pair.
Outstanding advantages of the present invention is:
1, the subchain of executing agency's motion control is formed by column, the 5th connecting rod, six-bar linkage and principal arm, improve the rigidity of robot, and the design of rocking arm movable type improves the working space of robot greatly, the dead-centre position of mechanism can be avoided, the sphere of action of Neng Shi robot is larger, and Neng Shi mechanism better keeps balance;
2, motor is arranged on rocking arm joint, drives closed loop chain movement, thus indirectly drive tail end connecting rod by the revolute pair on four-bar mechanism, makes the mobility of executing agency and activity space larger, can reduce active moment;
3, motor is arranged on after principal arm, reduces the center of gravity of whole mechanism, and can the larger motor of installation power in mechanism, make executing agency can adapt in the complex jobs such as welding, spraying, carrying, handling, assembling, piling;
4, be connected with a with gemel connecting rod between linkage with executing agency, make actuator flexibility ratio higher, working space is larger than robot in the past, and lighter bar made by with gemel connecting rod, whole mechanism power performance can be made better and be easy to control, executing agency can also be made among a small circle to rotate 360 degree of round angles, and make mechanism can be applicable to more occasions, precision is higher;
5, lighter bar made by connecting rod, and make mechanism kinematic inertia little, dynamic performance is good;
6, compared with robot mechanism of the same type, under equal-wattage, work is more.
