Summary of the invention
The object of the present invention is to provide a kind of controllable multiple-connecting-rod mobile mechanical arm, major part drive motors is all installed on the rotating gantry, the motor that can solve traditional fisher's formula serial manipulator is arranged on hinge place, the problem such as cause arm heaviness, poor rigidity, inertia is large, joint error is accumulative, robot has good dynamic performance, can meet the requirement of high-speed overload carrying piling preferably.
The present invention achieves the above object by the following technical programs:
A kind of controllable multiple-connecting-rod mobile mechanical arm, comprises frame, mobile platform, the second driving lever, first connecting rod, second connecting rod, shoulder bar, toggle link, six-bar linkage, end effector, third connecting rod, waist bar, the 3rd driving lever, double leval jib and the tenth connecting rod;
Described rotary frame is connected on a mobile platform by the first revolute;
Described second driving lever one end is connected with rotary frame by the second revolute pair, the second driving lever other end is connected with first connecting rod one end by the 3rd revolute pair, the first connecting rod other end is connected with one end of second connecting rod by the 4th revolute pair, the other end of second connecting rod is connected with shoulder bar one end by the 6th revolute pair, the shoulder bar other end is connected with toggle link one end by the second compound hinges, the toggle link other end is rigidly connected by link and six-bar linkage one end, and the six-bar linkage other end is connected with end effector by the 12 revolute pair;
Described third connecting rod one end is connected with rotary frame by the first compound hinges, and the third connecting rod other end is connected on second connecting rod by the 5th revolute pair;
Described waist bar one end is connected with rotary frame by the first compound hinges, and the waist bar other end is connected on shoulder bar by the 7th revolute pair;
Described 3rd driving lever one end is connected with rotary frame by the first compound hinges, the 3rd driving lever other end is connected with double leval jib by the 8th revolute pair, the double leval jib other end is connected with the tenth connecting rod one end by the 9th revolute pair, and the tenth connecting rod other end is connected on the second compound hinges.
Outstanding advantages of the present invention is
1 robot working space is large, and flexibility ratio is high.
2, this mobile mechanical arm selects driven by servomotor, not only environmental protection, and is easy to realize Long-distance Control, reduces labor strength.
3, most of servomotor is installed on rotary frame, and robot motion's inertia is little, and dynamic performance is good, can meet the requirement of carrying at a high speed preferably.
