Abstract
The invention discloses a parallel mechanism used for entertainments. The parallel mechanism is characterized in that the parallel mechanism is parallel integrally, a movable platform and a static platform are connected through five branches, the first branch is located in the middle of the mechanism and plays a role in supporting, the other four branches are evenly distributed on the static platform, the left branch and the right branch are of the same structure, the front branch and the rear branch are of the same structure, and the static platform is connected with a ratchet wheel. Under the interaction of the ratchet wheel and a ratchet, the parallel mechanism can only move in the clockwise direction in the moving process, so that stability of mechanism movement is ensured.
Description
Technical field
Patent of the present invention relates to a kind of robot, specifically relates to a kind of parallel robot device for amusement.
Background technology
Parallel institution is because its precision is high, in real life, be widely used in the occasion such as lathe and processing, there are a lot of scholars to be studied for parallel institution both at home and abroad, most parallel institutions all have a silent flatform and moving platform, then connect moving platform and silent flatform by branch, in conjunction with the feature of present parallel institution and the seesaw feature that child plays now, design a parallel institution for amusement, this parallel institution is applied in above seesaw cleverly, the seesaw of designing not only can be realized rotation, play but also be applicable to Different Weight people.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, this patent provide a kind of with for the parallel institution on seesaw, this mechanism not only can change the impact of original seesaw in motion process, but also can realize the rotation in space, especially differentiated two of body weight is also suitable for.
Patent of the present invention solves the technical scheme that its technical problem adopts: adopt parallel institution as main body, parallel institution and indexing mechanism are combined dexterously, using manpower as power, by driving revolute pair, can realize mechanism and rotate in predetermined space.In order to be adapted to different crowds, crossbeam is above by can flexible mechanism forming, thereby realizes the different arm of forces by the length of adjusting bar above.
Compared with prior art, the beneficial effect of this patent is: mechanism is fairly simple, utilize dexterously the feature of parallel institution, realize the reasonably combined of moving platform and silent flatform, indexing mechanism and parallel institution have been merged, synthesized a kind of simple seesaw mechanism, this structure is relatively simple, easy to operate, cost is lower, goes for different crowds.

Detailed description of the invention
In the embodiment shown in fig. 1: a kind of seesaw mechanism that is main body by parallel institution, it mainly comprises parallel institution, indexing mechanism and frame, and wherein the moving platform 4 of parallel institution is as the crossbeam of seesaw, the silent flatform 6 of parallel institution is connected with indexing mechanism, and indexing mechanism is connected with frame.Parallel institution is mainly by middle supporting branch, and front and back branch and left and right branch form.Medial fascicle is mainly to be interconnected by revolute pair 2 and moving platform 4 by support bar 3, and the other end of cramp bar 3 is fixed on silent flatform 6, and silent flatform 6 is connected with frame 11 by revolute pair 7.All around Si Ge branch presents 120 degree along silent flatform 6 and distributes, and two branched structures of left and right are identical, and former and later two branched structures are identical.The branch of left and right is mainly interconnected by a parallelogram compound hinges 19 and moving platform 4, wherein one of them driving joint revolute pair 18 of parallelogram is as input joint, itself and pedal 5 interconnect, parallelogram compound hinges 19 other ends are connected with upper connecting rod 17 by left branch revolute pair I1, upper connecting rod 17 forms moving sets 16 with lower link 15, and lower link 15 is connected with silent flatform 6 by left branch revolute pair II14.Front and back branch is mainly connected with moving platform 2 by spherical hinge I21 by connecting rod 20 one end, and one end is connected with the connecting rod 12 with ratchet by spherical hinge II13, and other one end of the connecting rod 12 with ratchet is connected with silent flatform 6 by front branch revolute pair 8.In order to ensure that parallel institution can only, to a direction motion, be provided with ratchet 10 in motion process below the connecting rod 12 with ratchet, realizes moving platform 4 by the interaction of ratchet 10 and ratchet 9 and can only move along a direction in motion process.In order to ensure to try out in different crowds at seesaw, on the moving platform 4 of parallel institution, be added with adjustable part 22, it can realize elongation, goes for so different crowds.
Claims (3)
1. for a parallel institution for amusement, it is characterized in that: mechanism's entirety adopts parallel institution, adopts five branches to be connected between moving platform and silent flatform, in the middle of a branch is positioned at, all the other four branches present the layout of 120 degree.Left and right Liang Ge branch adopts the compound hinges of parallelogram, and the form of connecting rod and revolute pair is connected with moving platform, using two revolute pairs above parallelogram compound hinges as driving joint.Former and later two branches interconnect by former and later two faces of spherical hinge and moving platform respectively, then interconnect by connecting rod and other spherical hinge, in order to control the rotation direction of parallel institution, on silent flatform, be provided with ratchet mechanism, on the 6th connecting rod of former and later two branches, there is ratchet, thereby realize can only rotating along a direction of parallel institution.
2. parallel institution according to claim 1, is characterized in that: parallel institution adopts manpower as power, realizes the motion of whole mechanism by the driving of revolute pair.
3. parallel institution according to claim 1, is characterized in that: the structure of described overall parallel institution and the arrangement of five branches.
