Background technology
Traditional industrial robot end gripper can only carry out some simple tasks.However, increasing actual Application requirement robot end can realize more complicated and more intelligent operation, and simple end gripper can not meet reality The requirement of complex operations task.The advantages of robot delicate has highly versatile, grasping high precision, dexterity, good stability, As the effective scheme for solving complex operations task, one research side of hot topic of robot field is turned into since 20 th century laters One of to.
Robot clever hand finger decides grasping precision, the spirit of Dextrous Hand as the most important components of Dextrous Hand The performances such as skilful property, stability.
Chinese invention patent document CN101941205A, Chinese invention patent document CN 10163317A etc. are in the prior art Robot delicate design structure it is complicated, Dextrous Hand design is mostly that overall dimension is more much larger than staff, finger is excessively thick, It is heavy, it is difficult to capture small objects.And for example Chinese invention patent document CN1031228744, a kind of robot delicate, each Finger sets three joints and is closed by three groups of quadric chain lotus roots, is driven by a motor.Three movement rates in joint are by fixation Angle 1:1:1 bends simultaneously, it is impossible to realize the linkage transmission of different drive ratios, dexterity reduction.And for example Chinese invention patent is literary The Dextrous Hand design in CN1418765 is offered, the driver because needed for is more, system controls that difficulty is high, the reason such as producing cost is huge, Significantly reduce the practicality of robot delicate.And skillful finger rigidity is immutable, it is difficult to capture frangible object, it is impossible to Meet the compliance requirement of different-stiffness needed for grasping different objects.
The content of the invention
The present invention provides a kind of robot spirit of variation rigidity drive lacking to solve technical problem present in known technology Dab hand finger, the finger structure is simply compact, light weight, small volume, and link transmission ratio-variable between phalanges, motor needed for drive lacking It is few, it is possible to achieve variation rigidity is adjusted.
The present invention is adopted the technical scheme that to solve technical problem present in known technology:A kind of variation rigidity is owed to drive Dynamic robot clever hand finger, including distal phalanx, distal end cradle head, the proximal phalanx and near being sequentially connected from far near End cradle head, is wound with driving draught line on the near-end cradle head, the two ends of the driving draught line respectively with two Transmission traction line is connected, and two transmission traction lines are respectively wound around on two reels, two reels respectively by Two motors are driven, and the driving draught line and the transmission traction line are connected by spring;The distal end cradle head and institute Near-end cradle head is stated by train line rope drive;The different linkage cotton rope of multiple depth is provided with the distal end cradle head Winding slot I, is provided with the different linkage cotton rope winding slot II of multiple depth on the near-end cradle head.
The proximal phalanx and the near-end cradle head are fixed together by connection sheet I.
The distal end cradle head is using two collateral support end plate supportings, and the collateral support end plate is logical with the proximal phalanx Cross connection sheet II to be fixed together, the distal end cradle head is fixedly connected on the distal phalanx by connection sheet III Together.
The present invention has the advantages and positive effects that:One) clever hand finger uses drive lacking mode, and simple structure is tight Gather, light weight, small volume, driver number is few needed for drive lacking, also causes system control difficulty reduction;Two) clever hand finger The linkage transmission of different drive ratios can be realized between phalanges, presses what fixed angle bent simultaneously compared to traditional stable drive ratio movement rate Dexterity is higher for clever hand finger;Three) skillful finger can realize the tune of bending, stretching routine and the variation rigidity of finger Section, can meet the compliance requirement of different-stiffness needed for grasping different objects.In sum, the present invention has simple structure tight Gather, light weight, small volume, link between phalanges transmission ratio-variable, variation rigidity, the features such as drive lacking, can complete various dexterous and multiple Miscellaneous operation task, can realize grasping manipulation under the limit or hostile environment instead of staff, there is wide in multiple fields Application prospect and important social effect.

Specific embodiment
For the content of the invention of the invention, feature and effect can be further appreciated that, following examples are hereby enumerated, and coordinate accompanying drawing Describe in detail as follows:
Fig. 1~Fig. 5, a kind of robot clever hand finger of variation rigidity drive lacking are referred to, including is connected successively from far near Distal phalanx 101, distal end cradle head 104, proximal phalanx 105 and the near-end cradle head 106 for connecing, rotate in the near-end and close Driving draught line 110 is wound with section 106, the two ends for driving draught line 110 are connected with two transmission traction lines 111 respectively, Two transmission traction lines 111 are respectively wound around on two reels 108, and two reels 108 are respectively by two electricity Machine is driven, and the driving draught line 110 and the transmission traction line 111 are connected by spring 107;The distal end cradle head 104 and the near-end cradle head 106 be driven by the cotton rope 109 that links;It is provided with multiple deep on the distal end cradle head 104 The different linkage cotton rope winding slot I of degree, is provided with the different linkage cotton rope coiling of multiple depth on the near-end cradle head 106 Groove II, linkage cotton rope 109 can be stretched in the linkage cotton rope winding slot I of different depth and linkage cotton rope winding slot II so that The linkage gearratio of proximal phalanx 105 and distal phalanx 101 can be adjusted, also can be by changing different near-end cradle heads And/or linkage of the distal end cradle head to realize different drive ratios is driven.Finger is realized when two direction of motor rotation are identical Bending and stretching motion, realized when two direction of motor rotation are differed finger variation rigidity regulation.
In the present embodiment, the proximal phalanx 105 and the near-end cradle head 106 are fixed by connection sheet I 102 and connected It is connected together.The distal end cradle head 106 using two it is collateral support end plates 103 support, it is described it is collateral support end plate 103 with it is described Proximal phalanx 105 is fixed together by connection sheet II 112, the distal end cradle head 104 and the distal phalanx 101 It is fixed together by connection sheet III 113.
Operation principle of the invention:
When two motors are all rotated counterclockwise, the near-end cradle head 106 is driven to rotate counterclockwise, so that institute State proximal phalanx 105 and the distal phalanx 101 is rotated counterclockwise, realize the stretching routine of finger.When two motors are all clockwise During rotation, the near-end cradle head 106 is driven to rotate clockwise, the proximal phalanx 105 and the up time of the distal phalanx 101 Pin is rotated, and realizes the bending motion of finger.When motor, one is rotated clockwise, and one when rotating counterclockwise, is realized the change of finger Stiffness tuning.
Although being described to the preferred embodiments of the present invention above in conjunction with accompanying drawing, the invention is not limited in upper The specific embodiment stated, above-mentioned specific embodiment is only schematical, be not it is restricted, this area it is common Technical staff, in the case where present inventive concept and scope of the claimed protection is not departed from, goes back under enlightenment of the invention Many forms can be made, these are belonged within protection scope of the present invention.
