Description
The present invention relates to the flexible manipulator mechanism of a kind of manipulator of flexible type and the hand organization of robot, particularly a kind of adaptive universal.
Existing manipulator, the hand organization of robot though style is a lot, have two types in general, and one type is the clamping device of rigidity, and one type is to have the manipulator that refers to or the hand organizations of robot of closing more.Simple, main folder and the card of plaing a part of the former finger structure is called clamper (or clamping device), in the application of industrial robot, for different workpiece, often needs to change clamper, and be both inconvenient, dumb again, influences operating efficiency.The latter has the manipulators that refer to that close more, its shape, action and function and people's hand is more approaching a step, some advantage, but its structure is comparatively complicated with control, each joint of finger must be installed a little motor or small-sized oil cylinder, or the driving-belt of driving and control.This mechanism involves great expense, and it is little to bear service load.
The objective of the invention is to provide a kind of manipulator of flexible type and this mechanism of hand organization of robot just can make each flexible finger motion active and intelligent with a power drive control, can grasp various abnormity and the object or the workpiece that vary in size in automatic synchronization ground, its structure is fairly simple with control, load capacity is big, cost is low, emulation is stronger, applied widely, and self adaptation that can operation under various environment and condition, general flexible manipulator mechanism.
The main structure of mechanism of the present invention, by flexible finger, flexible waist and flexible joint, palm that a kind of new flexible chain mechanism is formed, the commutation section of new structure and device thereof and arm hollow or tubular type are formed the sinking support skeleton of flexible manipulator mechanism.In the outside of sinking support skeleton, be surrounded by a kind of elastomeric material of similar skin sparing support framework, as the external protector of sinking support skeleton.Pass through in passage that all the driving controls and the transmission line of flexible manipulator mechanism all left in the sinking support skeleton or the hole, it drives control is to adopt the Abseiling device of one or a few (one group or several groups) interlock to carry out transmission, has branch's rope in the Abseiling device by shape automatic synchronization device interlock finger, at last drive control by a total cable traction, a power drive can be made deacclimatize with respectively pointing automatic synchronization in the object or the workpiece of the difformity that is grasped with size, and the motion posture of finger is respectively different to some extent, and this Abseiling device is called finger interlock Abseiling device.Another kind in the Abseiling device is to be used for driving respectively the motion of controlling each flexible joint (comprising flexible waist), this Abseiling device is called the flexible joint Abseiling device, these two kinds of Abseiling devices are linked to each other with the main frame of manipulator or robot respectively, drive and control by main frame and control system, like this, this flexible manipulator mechanism just can according to oneself the characteristics motion or carry out operation.
The main structure and the principal character thereof of mechanism of the present invention, function and effect, just concrete mechanism is described.Flexible finger is made up of a kind of new flexible chain mechanism, and this finger is suitable for grasping the object of various difformities and size, and the bending change of finger can change with the shape of grabbing object, always contact proper with grabbing body surface.Flexible manipulator mechanism has and singly refers to hand and the hand that refers to more, on the flexible manipulator mechanism that finger more than two is arranged, all is furnished with palm, and distribution and the arrangement mode pointed on palm are various.In the flexible manipulator mechanism of two or three fingers is arranged, the branch's rope that drives the control flexible finger merges in palm, by a total cable traction, driving merges the total finger interlock rope of this root of back just can make difformity or the big or small object automatic synchronization of each finger to being grasped.And in the flexible manipulator mechanism of finger more than three, in the space in palm, a shape automatic synchronization device must be set, with the motion of each finger of automatic synchronization.Branch's rope of each flexible finger is connected and interlock by shape automatic synchronization device in palm, and automatic synchronization ground drives control by a total cable traction.So just finished by the some flexible fingers on the power drive control flexible manipulator mechanism and carried out the automatic synchronization motion, grasped difformity and big or small object or workpiece.Thus, make the present invention have structure control and simply have the performance of adaptive universal.Flexible waist is the basic composition element by some similar gardens annular, at first be combined into a kind of support framework of flexible chain mechanism, generally make the support framework of the plain bending of single-degree-of-freedom, the driving control Abseiling device that is passed through in the skeleton all makes its rope remain on the flexural deformation neutral surface of flexible waist to pass through, and the finger interlock is coordinated to pass through on the center line of flexural deformation neutral surface that Abseiling device then remains on flexible waist.If flexible waist need have two frees degree, make bending motion all around, just must between these two plain bending support frameworks, a commutation section be set, in the commutation section, be provided with reversing arrangement.The commutation section will change the character of flexible waist, become spatial flexible mechanism by planar flexible mechanism.The effect of reversing arrangement is commutation section two to be driven the control rope keep stably carrying out the transition to another flexural deformation neutral surface from a flexural deformation neutral surface.Like this, in flexible manipulator mechanism, each drives the control rope carries out driving separately respectively and controls not affecting mutually, is independent of each other, and like this, can illustrate that structure of this mechanism and control are simple.Flexible waist structurally with athletic posture on all further emulation, good antitorque and stress performance is arranged, adapt to bigger load.Flexible joint comprises elbow joint or shoulder joint, and its structural shape is identical with flexible waist.Flexible arm must be hollow or tubular type, and links to each other with the flexible joint at its two, all is provided with reversing arrangement in the arm.An arm is actually long commutation section.If arm shortened flexible joint (or flexible waist) is extended, this flexible manipulator mechanism is exactly a kind of full compliant mechanism, and its profile and movement posture are as trunk.Flexible manipulator mechanism according to specific requirement, also can increase special attachment device in concrete the application.Flexible manipulator mechanism links to each other with main frame, and wherein each power drive control device of each Abseiling device and main frame is connected available hydraulic, air pressure or motor-driven respectively

Hinged continuously close refers to that flexible finger mechanism compares with the serialgram joint box-like flexible finger of groups of springs mechanism more, general weight own is bigger, the elastic force of wherein set resilience flexible apparatus is (this device can not be provided with very greatly) inadequately, therefore, must set up resilience reinforcement moving apparatus (33), by the interlock of rope (34), the device that increases the finger screen resilience is moved to and is installed in " body " of palm, arm or robot, make finger structure lightly flexible.The reinforcement moving apparatus can be spring, elastic rope or power drive.Above two embodiment mechanisms that exemplify, though textural bigger difference arranged, its textural association principle is identical with the basic skills of enforcement.
2. palm and shape automatic synchronization device
Flexible manipulator mechanism has the how branch of finger of Dan Zhiyu, is provided with the flexible manipulator mechanism of palm, is the above flexible manipulator mechanisms of two fingers at least.Arrangement and the distribution of finger on palm is divided into symmetrical expression and asymmetric.Symmetrical expression comprises symmetry in a row and garden dish radiation symmetry.Asymmetric comprises finger, and alternate a formula, garden dish are emanant to embracing, artifucial limb formula and special-shaped formula.
The palm housing is except that connecting finger and wrist, in being provided with the palm housing of four or more finger.Shape automatic synchronization device is set.The degree of crook difference of finger, the stroke of its soft drive control device (rope) are also different.If it is one to form lever-linked formula and make up that the soft drive control rope in per two or three fingers is joined, analogize with the method and to carry out multistage combination, draw and drive and control until merging into a total driving control rope at last, each clinodactyly degree all can be with the shape of the object that is grasped and size and automatic synchronization reaches various special-shaped objects of self adaptation or workpiece when grasping object.This lever-linked formula combined mechanism, the linkage of He Binging is called shape automatic synchronization device step by step.
Below with regard to the concrete enforcement body of palm and shape automatic synchronization device, comprehensive accompanying drawing 5 is further described.
(a) and (b) among Fig. 5, (c), (d), (e), (f) 6 branch term diagrams all are the mechanical schematic diagrams of the lever-linked formula combination of shape automatic synchronization device.
The branch's rope (9) that drives control referring to flexible finger among Fig. 1, Fig. 5, Fig. 1 is entering palm (2) lining, just with palm in shape automatic synchronization device be connected to each other.See Fig. 5, branch's rope (9) is hinged to one with the dynamic balance combined type interlock lever system (35) of shape automatic synchronization device, draw by a total flexible finger interlock rope (11) at last, carry out total driving and control, when driving finger interlock rope (11), comprehensive function and motion thereof by dynamic balance combined type interlock lever among Fig. 5, each position on each finger and the finger thereof is subjected to the resistance difference, finger has nothing in common with each other at the state of bending change and motion, just the stroke of the branch's rope (9) in the finger also has nothing in common with each other, in the case, carry out automatic synchronization by stress balance, newly carry out the transition to balance from unbalanced weight, make and respectively point stress equalization.Like this, by shape automatic synchronization device.A power drive control just can make many finger automatic synchronizations ground grasp the object of various difformities and size or workpiece and reach self adaptation, general purpose.
The different permutations and combinations methods of finger on palm, shape automatic synchronization device is structurally variant slightly, as the (a) and (b) among Fig. 5, (c) three components represented to be adapted to double-row type asymmetric to embracing a formula permutations and combinations pattern, (36) are double synchronous merging device among the figure, draw by finger interlock rope (11) merging, such two row's finger soft drive controls are synchronized with the movement, and the finger on each row then can automatic synchronization.Like this, make the more perfect function of hand flexible.(d) among Fig. 5, (e), (f) component are represented, are adapted to the garden emanant permutations and combinations mechanism of dish, are adapted to grasp the block object or the workpiece of various abnormity.
According to this principle and method, can apply in a flexible way in actual applications.For example the finger shape automatic synchronization device on the artifucial limb just can at first adopt thumb and other four finger to form double synchronous merging device, forms the soft drive control branch Abseiling device of secondary automatic synchronization then on other four fingers.Like this, the motion of each finger is just very flexible.
3. flexible waist, joint, arm and control thereof and transmission device.
The flexible waist of adaptive universal flexible manipulator, flexible joint all are by some annulars, the sheet shape that has multiple hole or various housing shape joint segmentation combination continuously successively, form chain type combined mechanism or torsion proof chain type combined mechanism.On the basis of chain type combined mechanism, orienting device is installed, the resilience flexible apparatus.Like this, the elastic bearing mechanism of just having formed flexible waist or flexible joint.This mechanism is structurally than flexible finger mechanism complexity, mainly be to solve multiple degrees of freedom, many power lines and various transmission control circuit all pass through in flexible waist, joint, the problem that drives, controls and transmit, outside in flexible waist, joint, have " skin " formula outer peripheral protection unit of elasticity or sealing except that installing, do not have other device.
The flexible waist of one degree of freedom and the bending motion in joint can be regarded the motion in a plane as.On structural shape, be analogous to single flexible finger mechanism.Multivariant flexible waist and joint, its motion are a kind of spatial movements, and this mechanism is exactly an a kind of flexible space mechanism.The key of the space mechanism in flexible waist and joint not only is the elastic bearing mechanism of itself, but this in-house set and various power and transmission line that pass through are passed through smoothly, and when mechanism kinematic, various power drive control circuits drive separately and control, do not affect influence and constraint mutually.Control program and controlling organization like this, have just been simplified.
Transmission, pipe-line are as long as it is just passable to leave enough strokes in the lateral space in each flexible joint.The soft drive control device initiatively and the rope of institute's interlock thereof, for each the branch's power soft drive that makes control flexible waist, joint is controlled rope under each self-driven situation, do not affect influence mutually, just must make dynamic Control drive Abseiling device moves along whole compliant mechanism flexural deformation neutral surface, in flexible waist, joint, be arranged on the method and the device thereof of the transmission route that is carried out on this flexural deformation neutral surface, be called flexural deformation neutral surface method and device thereof.Multivariant flexible waist, the spatial flexible mechanism in joint, when flexible joint change direction the beginning another free degree motion the time, will a new flexural deformation neutral surface appears, turnover or sudden change will take place in this new flexural deformation neutral surface, the rope of power drive control device and interlock thereof will adapt to this new turnover or sudden change thereupon, like this, just must increase a commutation section, the function of commutation section has been transitional effect, and the rope that guarantees to be provided with its interior power drive control device and interlock thereof transforms to another flexural deformation neutral surface with a flexural deformation neutral surface and gets on.
Commutation section operated by rotary motion is in the middle part in flexible waist and joint.If be connected with the hollow arm of rigidity in flexible manipulator mechanism, this arm itself just can commutation section of double as.
Below, with regard to the specific embodiment mechanism of flexible waist, joint and flexural deformation neutral surface and converting means thereof, 6,7,8 be further described in conjunction with the accompanying drawings.
Fig. 6 is the flexural deformation dynamic schematic diagram in flexible waist, joint.
Fig. 7 is the dynamic schematic diagram that commutation section flexural deformation neutral surface is changed direction.
