Abstract
The present invention discloses a kind of dual drive four-freedom space parallel mechanism.It is characterized in that: the moving platform that is parallel to each other (1) and fixed platform (10) are connected by four identical branches of structure, the rectangular distribution of tie point of four branches and moving platform (1) and fixed platform (10), two actuation movement pairs in each branch are respectively first moving sets (4) between second moving sets (8) that is connected with fixed platform and two Hooke's hinges.But the three-dimensional rotation of moving and winding in the present invention implementation space perpendicular to fixed platform (10) axis.Eight moving sets of mechanism can also can be imported as the driving of mechanism separately simultaneously.4-PUU and two kinds of parallel institutions of 4-UPU have been merged in essence in this mechanism, but are different from the direct series connection of two kinds of parallel institutions.Structure is simple relatively except that having in the present invention, symmetrical configuration and the positioning accuracy advantages of higher because the redundancy properties of its input makes that its working space is bigger, flexibility is higher, be specially adapted to big stroke, high-precision grand/little driven machine people's occasion.
Description
Technical field
The invention belongs to parallel institution and learn the field, particularly relate to a kind of dual drive four-freedom space parallel mechanism.
Background technology
In fields such as military engineering, optical communication engineering, bioengineering and precision optical machinery engineerings, applied robot system is had higher requirement, particularly, require robot in big space, to realize nano level motion positions precision at aspects such as the motion positions precision of robot, response speed, flexibilities.These more and more higher requirements make the robot system of traditional employing single drive mode more and more be difficult to be competent at.And macro/micro driven machine robot system is better than traditional single drive mode robot system in the performance aspect a lot, and characteristics such as the low inertia that it had, high accuracy, DOF (degree of freedom) redundance are that single driven machine robot system does not possess.Traditional grand/little driven machine robot system is directly to the series connection of two single driven machine robot systems, its complex structure, takes up room greatlyyer, and its application performance is restricted in many cases.
Summary of the invention
In order to overcome the prior art above shortcomings, the invention provides a kind of three-dimensional dual drive four-freedom parallel institution that rotates with one dimension that moves that has, it is different from the direct series connection of two kinds of parallel institutions, it has merged two parallel-connection structure 4-PUU and 4-UPU in fact in one, it is simple in structure, working space is big, the flexibility height.
The technical solution adopted for the present invention to solve the technical problems is: this mechanism is made up of moving platform that is parallel to each other and the fixed platform driving branch identical with four structures that are connected moving platform and fixed platform, wherein: have two moving sets secondary as driving in each branch, these two drive pair is moving sets that is connected with fixed platform and the moving sets that is connected two Hooke's hinges.4-PUU and two kinds of parallel institutions of 4-UPU have been merged in essence in this mechanism, are not only again the series connection of two kinds of mechanisms, eight in mechanism input moving sets can be separately also can be simultaneously as the input of mechanism.
Dual-driving parallel mechanism provided by the invention, made full use of the design feature of parallel institution, branch of mechanism is added redundant kinematic pair makes it merge two kinds of parallel institutions in itself, relatively in the past its member of double drive robot system still less, structure is simpler, compact.Sometimes do not need robot system to have the space six-freedom degree in actual applications, and the relative six-degree-of-freedom parallel connection mechanism of lower-mobility parallel institution it is simple in structure, control is relatively easy.Therefore the advantage of double drive lower-mobility parallel institution is integrated double drive robot system and lower-mobility parallel-connection structure has good application prospects.

Fig. 2 is the Hooke's hinge structural representation that connects lower link and upper pillar stand.
In Fig. 1,1. moving platform, 2. first Hooke's hinge is 3. gone up connecting rod, 4. first moving sets, 5. lower link, 6. second Hooke's hinge, 7. upper pillar stand, 8. second moving sets, 9. lower pillar stand, 10. fixed platform.
The specific embodiment
Accompanying drawing 1 is an embodiment disclosed by the invention.This mechanism is by moving platform 1, fixed platform 10 and be connected moving platform and four identical branches of structure of fixed platform form, and two moving sets is arranged as driving in each branch.Moving platform 1 is connected with last connecting rod 3 by first Hooke's hinge 2, last connecting rod 3 is connected with lower link 5 by first moving sets 4, lower link 5 is connected with upper pillar stand 7 by second Hooke's hinge 6, and upper pillar stand 7 is connected with lower pillar stand 9 by second moving sets 8, and lower pillar stand 9 connects firmly with fixed platform 10.The rectangular distribution respectively of the tie point of four branches and moving platform 1 and fixed platform 10, the moving platform 1 and the fixed platform 10 that are formed by connecting by the branch of four symmetrical distributions are parallel to each other.First Hooke's hinge 2 is rotationally connected with upper mounting plate 1, and second Hooke's hinge 6 is rotationally connected with upper pillar stand 7.
The present invention is dual drive four-freedom space parallel mechanism, and this mechanism has merged in essence Two kinds of parallel institutions of 4-PUU and 4-UPU, it is different from the direct series connection of above-mentioned two kinds of mechanisms. This machine In the structure, eight input moving sets can be separately also can be simultaneously as the input of mechanism. The present invention is integrated Double drive robot system and lower-mobility parallel-connection structure, except to have structure relatively simple, symmetry Outside advantage because the redundancy properties of its input, improved the parallel robot mechanism space little, The deficiencies such as very flexible, be applicable to big stroke, high accuracy grand/little driven machine people's occasion, have fine Application prospect.
