accompanying drawing 3 is embodiment's 2 of the present utility model structural representation.
wherein: 10,10 '-rub assembly; 1,1 '-gear; 2,2 '-connecting rod; 3,3 '-bearing pin; 4,4 '-chute; 5,5 '-slide block; 6,6 '-guiding element.
Embodiment
below in conjunction with accompanying drawing and specific embodiment, the technical solution of the utility model is further elaborated.
referring to the both hands shown in Fig. 1, Fig. 2, rub bio-mechanism, 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 gear 1 ' in frame, by bearing pin 3 ', be located at rotationally the connecting rod 2 ' on gear around shaft axis, and center hinge is connected in frame for the slide block 5 ' of connecting rod 2 ' guiding is provided, when 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 Fig. 1, Fig. 2, rub the gear 1 on assembly 10 and rub the intermeshing setting of gear 1 ' on assembly 10 ', like this by a gear rotation in external drive mechanism actuation gear 1 and gear 1 ', another gear gets final product counterrotating, so just makes to rub assembly 10 and rubs assembly 10 ' and work simultaneously and produce the bionic movement that similar both hands are rubbed.
the fixing difference in functionality instrument of rubbing more respectively in connecting rod 2,2 ' lower end, just can form the both hands that function is different and rub bio-mechanism.
while arranging, can adjust as required bearing pin 3 place pin-and-holes position along the circumferential direction on gear 1, or adjust bearing pin 3 ' place pin-and-hole position along the circumferential direction on gear 1 ', thereby realize, both hands are symmetrical bionical rubs action (as Fig. 1), or realizes the asymmetric bionical action (as Fig. 2) of rubbing of both hands.
if change the radial position on 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 change the sense of rotation of gear 1,1 ' middle driving gear, just can switch from the inside to the outside and from outside to inside the direction of rubbing of connecting rod 2,2 ' lower end.
both hands shown in Figure 3 are rubbed bio-mechanism, and this bio-mechanism 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 a gear in external drive mechanism actuation gear 1, gear 1 ' rotates, 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.Single rubbing on assembly 10 in embodiment 1, only has 3 substantial motion members from kinematic meaning, i.e. gear 1, connecting rod 2, slide block 5; Single rubbing in assembly 10 in embodiment 2, only has 2 substantial motion members from kinematic meaning, i.e. gear 1, connecting rod 2.
innovative point of the present utility model is, with less mechanical component, just realized the plane motion that complicated imitation people both hands are rubbed, its structure is very simple, cost is cheap especially, functional reliability is high, can meet different industries for the demand of rubbing bio-mechanism, be also a kind of contribution to traditional mechanics simultaneously.This has formed high-definition contrast with existing those huge structures bionic device complicated, that cost is extremely high, can meet with extremely low cost the demand of all kinds of corresponding products to both hands kneading mechanism, 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.
