accompanying drawing 2 is embodiment's 2 of the present utility model structural representation.
wherein: 10,10 '-rub assembly; 1,1 '-worm gear; 2,2 '-connecting rod; 3,3 '-bearing pin; 4,4 '-chute; 5,5 '-slide block; 6,6 '-guiding element, 7, motor; 8, worm gear.
Embodiment
below in conjunction with accompanying drawing and specific embodiment, the technical solution of the utility model is further elaborated.
a kind of electronic both hands shown in Figure 1 are rubbed bionic device, comprise frame (not shown), be located in frame two groups rub assembly 10,10 ',
the setting of rubbing assembly 10 ' is with to rub arranging of assembly 10 similar, comprise and can be located at rotationally worm gear 1 ' in frame, by bearing pin 3 ', be located at rotationally the connecting rod 2 ' on worm gear around shaft axis, and center hinge is connected in frame for the slide block 5 ' of connecting rod 2 ' guiding is provided, when worm gear 1 ' externally rotates under the effect of driving force, connecting rod 2 ' hinged center with respect to slide block 5 ' under the effect of bearing pin 3 ' is not only done straight line sliding motion but also is swung, and the lower end of connecting rod 2 ' also just can produce and be similar to the bionic movement that staff is rubbed.
shown in Figure 1, in frame, be also provided with motor 7, be fixedly connected on the worm screw 8 that can match with worm gear 1,1 ' on motor 7 output shafts, rub the both sides that assembly 10,10 ' is located at respectively worm screw 8, and worm gear 1, the 1 ' setting that is meshed with worm screw 8 respectively.When motor 7 work, the output shaft of motor 7 drives worm screw 8 rotations like this, so just drives worm gear 1,1 ' rotation, thereby makes connecting rod 2,2 ' lower end produce respectively the bionical action that similar staff is rubbed.By the fixing instrument of rubbing of difference in functionality in connecting rod 2,2 ' lower end, just can form the electronic both hands that various functions are different and rub bionic device.
while arranging, can adjust position or the bearing pin 3 ' position on worm gear 1 ' of bearing pin 3 on worm gear 1 according to action need, thereby realize, both hands are symmetrical bionical rubs action (as Fig. 1), or realizes the asymmetric bionical action of rubbing of both hands.
if change the radial position on worm gear 1,1 ' respectively of bearing pin 3 or bearing pin 3 ' place pin-and-hole, changed the eccentric distance of pin-and-hole, can change respective link 2 or 2 ' lower end rubs the Motion curves of action.
if change slide block 5,5 ' the hinged center position in frame, can change rubbing position and rubbing the Motion curves of action of connecting rod 2,2 ' lower end simultaneously.
if make the output shaft counterrotating of motor 7 by control switch, just can change worm gear 1,1 ' sense of rotation, can switch from the inside to the outside and from outside to inside the direction of rubbing of connecting rod 2,2 ' lower end like this.
a kind of electronic both hands shown in Figure 2 are rubbed bionic device, and this bionic device and embodiment's 1 difference is mainly to provide the setting of connecting rod 2, the 2 ' parts that lead.In the present embodiment, centered by being provided, connecting rod 2, the 2 ' parts that lead are fixedly installed on the guiding element 6,6 ' in frame, guiding element 6,6 ' is located to Spielpassung respectively in chute 4,4 ', guiding element 6,6 ' the upper circumferential exterior surface matching with chute 4,4 ' length direction cell wall is cylndrical surface, and guiding element 6,6 ' forms planar higher pairs with chute 4,4 ' respectively.When worm screw 8 rotarilys actuate worm gear 1, worm gear 1 ' rotation, connecting rod 2,2 ' is not only done straight line motion but also is swung with respect to the guiding element 6,6 ' of cylindrical outer surface respectively under bearing pin 3,3 ' effect, and connecting rod 2,2 ' lower end just can produce the bionic movement that similar both hands are rubbed like this.
in above-mentioned movement process, the guiding element 6 of cylindrical outer surface, 6 ' and chute 4,4 ' between friction less, compare embodiment 1 mode, can effectively reduce the friction and wear between guiding element and chute cell wall, but it is less that its bearing capacity is compared embodiment 1 mode, be applicable to the occasion that load is less, embodiment 1 mode is applicable to the occasion that load is larger.The guiding element 6,6 ' of cylindrical outer surface can adopt the parts such as straight pin, rolling bearing, sliding bearing, if adopt simple fixed cylinder pin, its cost is minimum, but friction and wear is relatively large, and fixing rolling bearing or the sliding bearing in employing center can reduce friction and wear effectively.
to sum up, as how less or minimum moving link, come innovative design to go out to imitate the mechanism that both hands are rubbed, all the time be a technical barrier in mechanics field, because as Yi Ge mechanism, moving link not only means simple in structure and low cost of manufacture less, the more important thing is that to mean functional reliability high.
one-sided rubbing in action in embodiment 1, only has 4 substantial motion members from kinematic meaning, i.e. worm screw 8, worm gear 1(1 '), connecting rod 2(2 '), slide block 5(5 '); One-sided rubbing in action in embodiment 2, only has 3 substantial motion members from kinematic meaning, i.e. worm screw 8, worm gear 1(1 '), connecting rod 2(2 ').
innovative point of the present utility model is, only utilize very simple worm screw 8, worm gear 1(1 '), connecting rod 2(2 '), center hinge is connected on the slide block 5(5 ' in frame) or center be fixed on the guiding element 6(6 ' of the cylindrical outer surface in frame), just realized the plane motion that complicated imitation both hands are rubbed, the fixing instrument of rubbing of difference in functionality in connecting rod 2,2 ' lower end, just can form the electronic both hands that various functions are different and rub bionic device.This bionic device structure is very simple, and cost is cheap especially, and functional reliability is high, can meet different industries for the demand of rubbing bionic device.This has formed high-definition contrast with existing those huge structures bionic device complicated, that cost is extremely high, can promote the use of widely.
above-described embodiment is only explanation technical conceive of the present utility model and feature, and its object is to allow person skilled in the art can understand content of the present utility model and implement according to this, can not limit protection domain of the present utility model with this.All equivalences of doing according to the utility model Spirit Essence change or modify, within all should being encompassed in protection domain of the present utility model.
