A kind of multiple degrees of freedom main manipulator with linkage
Technical field
The present invention relates to robotics are and in particular to a kind of multiple degrees of freedom main manipulator with linkage.
Background technology
With scientific and technical development, application in people's productive life for the robot is more and more extensive, and mostly is at present
Master-slave mode remote operating structure, human users' main manipulator passes through the motion from terminal structure of telecommunication and computer controls.This
No longer have geographic restriction between operator and operation target, operator being just operable to robot thousands of miles away,
And because this mode does not need operator not at the scene, away from dangerous or unfavorable environment.Meanwhile, this master-slave mode
Structure is passed through software and can directly be operated, with personnel, the shake that apparatus brings, and then reduces the operational error rate of doctor, improves essence
Really property, stability and safety.Additionally, operator can be sitting in being operated on comfortable, pleasant control station, greatly drop
Low feeling of fatigue.
Had many kinds in prior art, wherein close to this invention technology be realize attitude part 3 from
By spending, the action of 3 degree of freedom of redundant degree of freedom and position.Functionally simulation arm reach position (for upper and lower, left and right,
In front and back), the attitude (pitching, beat and rotation) of staff.Redundant degree of freedom is the Singularity avoiding staff attitude.But it is existing
Attitude part-structure in technology is unable to be in horizontality, brings very big difficulty in gravitational equilibrium and power drive
Degree;Or the range of movement that because of architectural characteristic in parallel etc. is is less.

Mutually engage;Rise avoiding device to include rotating base 500, avoid motor 52, threaded rod 520 and some leads 521;Right connecting rod
61 right-hand member form the screwed hole 6100 running through up and down and centered on screwed hole 6100 circle distribution pilot hole 610;Rotation
Turn base 500 to be articulated on the swivel base 50 of middle part;It is fixed with avoidance motor 52 upwards on the upper surface of rotating base 500 and circumference divides
Some leads 521 of cloth;It is fixedly connected with threaded rod 520 on the take-off lever avoiding motor 52;Threaded rod 520 and right connecting rod 61
It is spirally connected;Lead 521 is plugged in the pilot hole 610 of right connecting rod 61.
Preferred as technique scheme, portion 621 is slided on a left side and the right side slide the lower surface in portion 611 respectively with left connecting rod 62
Concordant with the lower surface of right connecting rod 61.
Main manipulator has 7 degree of freedom, wherein attitude 3, redundancy 1, position 3;
Positional structure is equivalent to the effect of the arm of people, that is, in whole range of movement manipulator can reach any
Position.In mechanism, swivel base 10 can be rotated along axis A by rotary shaft 20;Upper arm 30, underarm 40 and transposase 11 0, middle part swivel base 50
Collectively form parallelogram sturcutre, upper arm 30 can make waling stripe 60 remain with underarm 40 when rotating along axis B
Horizontality;Waling stripe 60 can rotate along axis C, and 3 degree of freedom of such axis A, B, C just constitute position portion
Point, overall structure optional position motion up and down, around can be accomplished.
Attitude structure is equivalent to the wrist of people, being capable of upper and lower, around any attitude.Redundancy connecting rod 70 is along axis D
Rotation, pitch link 80 rotates along axis E, and beat connecting rod 90 rotates along axis F, and rotary handle 91 rotates along axis G, thus
Operator are had to hold 3 attitudes that rotary handle can be accomplished.
It may appear that situation about colliding in upper arm 30 in rotary course, this is to start to avoid motor 52 to waling stripe 60,
Drive waling stripe 60 to rise, be thus avoided that the situation of collision, then start cover motor 622, drive under left connecting rod 62
Fall is to fill up the climb of the waling stripe 60 producing as avoidance.So virtually increase the opereating specification of manipulator.
Above content is only the better embodiment of the present invention, for those of ordinary skill in the art, according to the present invention
Thought, all will change in specific embodiments and applications, this specification content should not be construed as to this
Bright restriction.
