The operation principle of present embodiment, like Fig. 5, Fig. 6, Fig. 7, Fig. 8, Fig. 9, Figure 10 and shown in Figure 11, narrate as follows:
This initial position that installs under a kind of situation is as shown in Figure 5; In this case; Middle finger section 4 does not all contact object with the end section of finger 6 when initial, and object 9 is nearer apart with middle finger section 4, and finger can at first touch object 9 by middle finger section 4 in rotation process.When motor 2 had just begun to rotate, middle finger section 4 was the state that finger stretches with terminal section of finger 6 and pedestal 1.When using robot finger's grasping objects 9 of the utility model; The output shaft of motor 2 rotates; Driving the nearly joint shaft 3 that is connected with second gear 62 through first gear 61 rotates; Because the effect of contraction of the first spring spare 41, middle finger section 4 is fixed together with nearly joint shaft 3 seemingly, and middle finger section 4 will be around nearly joint shaft 3 rotational angle α.
Because first bevel gear 21 is connected with pedestal 1 through the second spring spare 42; In middle finger section 4 rotation processes; Joint shaft 5 far away will change with respect to the position of nearly joint shaft 3, because the following bevel gear 311 of bipyramid gear 31 and 21 engagements of first bevel gear, so the rotation of middle finger section 4 can make the go the long way round center line of joint shaft 5 of second bevel gear 22 of 312 promotions of last bevel gear and its engagement of bipyramid gear 31 rotate a same angle [alpha]; When first bevel gear 21 is consistent with second bevel gear, 22 sizes; Diarticular coupled rotation angle is 1: 1, and certain first bevel gear 21 also can be designed as different sizes with second bevel gear 22, then will obtain the different coupling effect; Because second bevel gear 22 is affixed with joint shaft far away, will make joint shaft 5 far away again around self axis rotational angle α.
Because the version of the 3rd transmission mechanism and spring spare distributing position is different, the 3rd spring spare 43 production processes are also different with deflection, below just introduce production process in two kinds of embodiments in detail.
When adopting first kind of embodiment; The output shaft of motor 2 rotates; Drive the nearly joint shaft 3 that is connected with first driving wheel 11 through first gear 11 and second gear 12 and rotate, first driving wheel, 11 pullings, first driving member 13 makes the driven pulley 12 of the winning joint shaft 5 rotational angle α that go the long way round.Because middle finger section 4 has also been rotated angle [alpha] around nearly joint shaft 3 at this moment, so first driven pulley 12, therefore connects the 3rd spring spare 43 generation certain deformation amounts of the joint shaft 5 far away and first driven pulley 12 with respect to the not change of position of middle finger section 4.
When adopting second kind of embodiment; The output shaft of motor 2 rotates; Driving second bevel gear 22 that links to each other with nearly joint shaft 3 through the 3rd spring spare 43 through first gear 11 and second gear 12 rotates; Because bipyramid gear shaft 310 is around the axis rotational angle α of self; Simultaneously bipyramid gear 31 along with middle finger section 4 around nearly joint shaft 3 axis rotational angle α, these two kinds of effects stacks cause second bevel gear 22 with following bevel gear 311 engagements of bipyramid gear 31 around nearly joint shaft 3 axis rotational angles 2 α, thus this moment the 3rd spring spare 43 deflection be 2 times of the first spring spare 41.
At this moment, because the end section of finger 6 is fixed on the joint shaft 5 far away, also thereupon the go the long way round center line rotational angle α of joint shaft 5 of the end section of finger 6, as shown in Figure 6.This process is run into object 9 up to middle finger section 4, and middle finger section has been rotated angle beta around nearly joint shaft, and also the go the long way round center line of joint shaft of the end section of finger has rotated angle beta, and is as shown in Figure 9.Said process is two joints and adopts coupled modes to rotate.
At this moment, if the end section of finger 6 contact objects 9 then accomplish grasping, employing be to grip the mode grasping objects.As shown in Figure 9.
At this moment, if the end section of finger 6 does not also contact object 9, as shown in Figure 7.The output shaft of motor 2 is rotated further, and drives through spring spare 43 and first bevel gear 21 of nearly joint shaft 3 sockets through first gear 11 and second gear 12 and rotates.
Because at this moment middle finger section 4 contacted object 9, middle finger section 4 can not continue to rotate around nearly joint shaft 3, the continuation distortion of the first spring spare 41 will make middle finger section 4 with increasing grasp force near object 9.Simultaneously because the deflection of the 3rd spring spare 43 is big than the deflection of all the other two spring spares; So along with being rotated further of motor 2; The 3rd spring spare 43 meeting drives first bevel gear 21 is rotated further around the axis of nearly joint shaft 3; Thereby the following bevel gear 311 that drives bipyramid gear 31 is rotated further, and second bevel gear 22 that last bevel gear 312 feasible and bipyramid gear 31 meshes is rotated, again because second bevel gear 22 and joint shaft 5 far away are affixed; To make joint shaft 5 far away be rotated further, the axis rotation of joint shaft 5 thereby the terminal section of finger 6 can continue to go the long way round around self axis.This process touches object 9 up to the end section of finger 6, accomplishes and grasps action, and is as shown in Figure 8.This process makes this device can adapt to the object that grasps difformity and size automatically.
The initial position of this device under another kind of situation is shown in figure 10, and in this case, object 9 is nearer apart with the end section of finger 6, can at first touch object by the end section of finger in this case.Finger can rotate with the sort of coupling extracting pattern recited above always in this case; Till the end section of finger 6 touches object; Completion grasps; Do not carry out the under-driven adaptive pattern in the motion process of finger in this case, finger is directly accomplished through coupling extracting pattern and grasped, and is shown in figure 11.
The above is merely the preferred implementation of the utility model; Should be understood that; For those skilled in the art; Under the prerequisite that does not break away from the utility model know-why, can also make some improvement and retouching, these improvement and retouching also should be regarded as the protection domain of the utility model.
