Belt wheel multi-joint high under-driven robot finger device of the present invention, said spring spare adopts torsion spring, extension spring, stage clip, sheet spring, leaf spring, clockwork spring, rubber band or elastic threads.
In the present embodiment, said spring spare: promptly the first spring spare 12 and the second spring spare 16 adopt torsion spring.
Belt wheel multi-joint high under-driven robot finger device of the present invention, the elastic force restriction of a j spring spare is better than the elastic force restriction of a j-1 spring spare, and j is 2 any numbers to the section of the finger number of middle part.
The elastic force restriction of the said second spring spare is better than the elastic force restriction of the first spring spare.
The operation principle of present embodiment as Fig. 8, Fig. 9, Figure 10, Figure 11, Figure 12, Figure 13, Figure 14, Figure 15, Figure 16, Figure 17, Figure 18, is described below:
The original state of present embodiment such as Fig. 8, shown in Figure 9, similar people's finger straight configuration.
When present embodiment grasped object, motor 2 rotated, and drove decelerator 17 and rotated, and drove second gear 19 that is engaged with by first gear 18 and rotated, and the nearly joint shaft 3 affixed with second gear rotates, and drove first driving wheel 9 affixed with it and rotated.Because the common restriction of the first spring spare 12, the second spring spare 16, the first middle part section of finger 4, the second middle part section of finger 6 and the end section of finger 8 be one " rigid body " seemingly, and therefore the rotation of first driving wheel 9 will be done as a whole axis rotation around nearly joint shaft 3 by first driving member, 10 pullings, the first middle part section of finger 4, the second middle part section of finger 6 and the terminal section of finger 8.Can run into three kinds of situations this moment:
(a) the end section of finger 8 is run into object, as shown in figure 18, grasps and finishes.
(b) the second middle part section of finger 6 is run into object, as shown in figure 16, this moment, first driving wheel 9 was rotated further, successively by first driving member 10, first driven pulley 11, middle joint shaft 5, second driving wheel 13, second driving member 14, second driven pulley 15, joint shaft 7 far away, the go the long way round axis of joint shaft 7 of the distortion elastic force that the terminal section of finger 8 of pulling is overcome the second spring spare 16 rotates, and the second spring spare 16 deforms at this moment, touches object up to the end section of finger 8, as shown in figure 17, grasp end.
(c) the first middle part section of finger 4 is run into object, as Figure 10, shown in Figure 11, because the elastic force restriction of the second spring spare 16 is better than the elastic force restriction of the first spring spare 12, this moment, first driving wheel 9 was rotated further, successively by first driving member 10, first driven pulley 11, middle joint shaft 5, second driving wheel 13, second driving member 14, spur the second middle part section of finger 6, the end section of finger 8 is done the as a whole axis rotation that overcomes the distortion elastic force of the first spring spare 12 around middle joint shaft 5.If the end section of finger 8 is run into object, then grasp and finish; Otherwise if the second middle part section of finger 6 is run into object, as shown in Figure 12 and Figure 13, this moment, first driving wheel 9 was rotated further, successively by first driving member 10, first driven pulley 11, middle joint shaft 5, second driving wheel 13, second driving member 14, second driven pulley 15, joint shaft 7 far away, the go the long way round axis rotation of joint shaft 7 of the distortion elastic force that the terminal section of finger 8 of pulling is overcome the second spring spare 16, this moment, the second spring spare 16 deformed, touch object up to the end section of finger 8, as Figure 14, shown in Figure 15, grasp and finish.
When decontroling object, motor 2 counter-rotatings drive decelerator 17 counter-rotatings, and 18 counter-rotatings of first gear drive second gear 19, nearly joint shaft 3 and 9 counter-rotatings of first driving wheel.By first driving member, 10 pullings, first driven pulley 11, middle joint shaft 5,13 counter-rotatings of second driving wheel, by second driving member, 14 pullings, second driven pulley 15, joint shaft 7 far away, 8 counter-rotatings of the end section of finger, the distortion of the second spring spare 16 simultaneously reduces thereupon gradually, this moment the terminal section of finger 8 be inverted to its with respect to the second middle part section of finger 6 initially stretch the position, shown in Figure 12,13.Owing to above the back of the second middle part section of finger 6 boss is arranged, this boss surpasses the position that finger stretches when the confinement end section of finger 8 is reversed, and plays a position-limiting action, and the therefore terminal section of finger 8 is subjected to the backward rotation again that stops of the second middle part section of finger 6.Second driving member 14 will spur the second middle part section of finger 6 of having stretched and the end section of finger 8 and do as a wholely to reverse around the axis of middle joint shaft 5 together this moment, the distortion of the first spring spare 12 simultaneously reduces thereupon gradually, this moment the second middle part section of finger 6 backward rotation to its with respect to the first middle part section of finger 4 initially stretch the position, as Figure 10, shown in Figure 11.Owing to above the back of the first middle part section of finger 4 boss is arranged, this boss surpasses the position that finger stretches in the time of will limiting 6 counter-rotatings of the second middle part section of finger, plays a position-limiting action, and therefore the second middle part section of finger 6 is subjected to the backward rotation again that stops of the first middle part section of finger 4.First driving member 10 will spur the first middle part section of finger 4, the second middle part section of finger 6, the end section of finger 8 of having stretched and do as a whole together around the axis backward rotation of nearly joint shaft 3 this moment, return to the position of stretching that begins most fully up to device, as Fig. 8, shown in Figure 9.
The present invention utilize many to belt wheel mechanism, socket activity a plurality of middle part sections of finger and the decoupling zero effect that a plurality of spring spare had comprehensively realized the crooked special-effect that grasps object of the high under-actuated finger of multi-joint.
