Description
Technical field
The invention belongs to robot technical field, more particularly to the flat folder of a kind of crank rocker dynamic gear train straight line is adaptive
The structure design of finger apparatus.
Background technology
Robot is the important device for realizing crawl object.The method of crawl object is limited from opposite both direction
The firmly movement possibility of object in this direction.There are multiple directions for the movement of object in space, in order to limit grabbed object
Various movement possibilities, need robot from all directions limited object move.Parallel clamping crawl (referred to as flat gripper
Take) it is a kind of common grasp mode, end segment remains the relatively-stationary appearance of palm opposite pedestal during the motion
State, in the process of grasping, opposite two fingers or multiple fingers contact object in two or more sides of object and apply
Add grasping force, soft finger face is obtained by the elastic deformation material of finger surface always improves the stability of crawl, this parallel
The machine of clamping is by industrial extensive use, referred to as industrial clamper.Industrial clamper refer to have it is two or more
Finger does not have the machine in joint or the joint of multiple coupled motions on finger, when capturing object using the mode of parallel clamping,
Or extreme apex carries out grip to object, this grasp mode is effective for every-day object, can reach most types
Grasping body.
The robot for imitating human hand has many joint freedom degrees at present, is controlled respectively by multiple motors, also referred to as
Dextrous Hand, Dextrous Hand are defined as at least tool there are three finger, there is nine an or more degree of freedom, it needs to be determined that gestures of object when crawl,
Path planning is carried out to the route in space, determines that object space is laid out, these all bring complicated control.Thus traditional spirit
Dab hand is more expensive.
Traditional drive lacking hand drives more joint using few driver, energy conservation and environmental protection, and weight is low.Traditional deficient drive
It starts only to have and first rotates nearly joint, be rotated further by the rigid crawl in remote joint, it, cannot be with end although being adapted to shape

In the present embodiment, the spring 9 uses tension spring.
The operation principle of the present embodiment, is described below in conjunction with attached drawing：
In the present embodiment, it sets initial position to the vertical state of third connecting rod 73 (as shown in Figure 2).
Motor 12 rotates, and drives the rotation of the second axis 52 by transition transmission mechanism 200, the first driving wheel 61 is around the second axis
52 center line rotation；Because first connecting rod 71, second connecting rod 72, third connecting rod 73, pedestal 1 constitute four-bar mechanism, and
Meet condition (as shown in figure 13)：
A) length of line segment AB is equal to 2 times of line segment BC length,
B) the length three of the length of line segment CD, the length of line segment DE and line segment AD is equal,
C) length of line segment CD is equal to 2.5 times of line segment BC length,
As shown, the four-bar mechanism will be because the rotation of first connecting rod 71 drives remote joint shaft 5 to move along a straight line.
Then the second segment 3 will be along linear translation, as shown in figure 12.
When the rotation angle of convex block driver plate 8 is 0 degree, spring 9 hauls convex block driver plate 8 against in limited block 11 at this time
On, when center line rotation of the third connecting rod 73 around first axle 51, under the action of the first driving member 81 and the second driving member 82,
The transmission of first driving wheel 61 to the 4th driving wheel 64 is co-rotating transmission and is step-up drive (transmission ratio is less than 1), is passed in third
Under the action of moving part 83 and the 4th driving member 84, the transmission of the 5th driving wheel 65 to the 8th driving wheel 68 be co-rotating transmission and for etc.
Speed transmission (transmission ratio be equal to 1) because the effect of contraction of spring 9 by convex block driver plate 8 in the first stage when against limited block 11, the
Eight driving wheels 68 will not rotate relative to the second axis 52, the second segment 3 with the 5th driving wheel 65 in the first stage when keep
The posture constant relative to pedestal 1.
When the present embodiment captures object 100, will present two kinds of grasp modes, i.e., the flat clip mode of straight line (first stage) and
Adaptive envelope grasp mode (second stage):
A) when the second segment 3 contacts object 100 prior to the first segment 2, which will be using the crawl mould of the flat folder of straight line
Formula.The transmission that motor 12 passes through transition transmission mechanism 200 at this time so that the second axis 52 rotates, and first connecting rod 71 will be around second
Axis 52 rotates, and is rotated around first axle 51 with third connecting rod 73, the state of translation so that remote joint shaft 5 is in line,
Under the pulling of spring 9, affixed convex block driver plate 8 will be close to limited block 11 with the 8th driving wheel 68, make the 5th driving wheel 65, the
Six driving wheels 66, the 7th driving wheel 67, the 8th driving wheel 68 are unable to opposite base 1 and rotate, can only be along with respective
Central shaft is translatable, and the second segment 3 is made to remain initial posture in the first stage, until the second segment 3 touches object
100, at this time motor 12 be stopped, to realize that the straight line of the device equals folder function.As shown in Figure 5 and Figure 6.
B) when the first segment 2 touches object 100 prior to the second segment 3, which will use adaptive envelope to capture
Pattern.After the first segment 2 touches object 100, the first segment 2 will be unable to rotate again, to first connecting rod 71, the
Two connecting rods 72, third connecting rod 73 also will be unable to rotate, and motor 12 is rotated further at this time, pass through the driving of transition transmission mechanism 200 the
One driving wheel 61 is rotated further, and the second driving wheel 62 of driving rotates around third axis 53.Third driving wheel 63 is around third axis
53 rotations, the 4th driving wheel 64 are rotated around remote joint shaft 5, to drive the 4th driving wheel 64, the transmission of the second segment 3 and the 5th
Wheel 65 rotates together, and the second segment 3 will be rotated around remote joint shaft 5, close to object 100, and the 8th driving wheel 68 is around the
Two axis 52 rotate, and convex block driver plate 8 is driven to leave limited block 11,9 stretcher strain of spring.Until the second segment 3 connects with object 100
It touches, motor 12 is stopped, and crawl terminates.As shown in Figure 7 to 9.For the object 100 of different shapes and sizes, the present embodiment
With adaptivity, the object of different shape and size can be captured.
When discharging object, motor reversal, with the above process just on the contrary, repeating no more.
Apparatus of the present invention are integrated real using motor, four-bar mechanism, multiple driving wheels, convex block driver plate, limited block and spring
The function of robot finger's straight line parallel clamping and self-adapting grasping is showed；The device can linear translation the second segment grip object
Body, also can envelope different shapes and sizes object；It is big that the device captures range；By the way of drive lacking, a motor is utilized
Two segments are driven, without complicated sensing and control system；The apparatus structure is compact, small, and manufacture is low with maintenance cost,
