Abstract
The utility model provides an on the basis, change electronic jar driving method into circular orbit driving method, make that but, 360 rotatory 6 -degree of freedom platform, at traditional 6 -degree of freedom platform the utility model discloses on the basis of satisfying traditional 6 -degree of freedom platform performance, realized around 360 gyrations on the z axle. This instance adopts the matured product that can directly buy more on the market, can shorten the production cycle of this instance, reduces product cost, and possible miniaturization to be used in the special industry.
Description
Technical field
This example relate to a kind of can 360 ° rotate six degree of freedom platform structures, upper table surface can be realized around central shaft 360 ° rotation.And this six degree of freedom platform structure is compact, can accomplish miniaturization.
Background technology
Along with the increase in six degree of freedom platform application field, the requirement of client to six degree of freedom platform is more and more higher, some industry to the features simple structure of free degree platform and lightweight requirements higher, this just means the structure needing to simplify free degree platform.
At present, on market, six degree of freedom platform is primarily of six electric cylinders, hinge seat, upper lower platform composition, and wherein the structure of electric cylinder is comparatively complicated, and cause the production cycle of six degree of freedom platform long, assembly difficulty is large.And the six degree of freedom platform of this structure is difficult to accomplish miniaturization.Blank in order to fill up this, we devise a kind of can 360 ° of miniaturized six degree of freedom platforms rotated.
Summary of the invention
In order to realize structural simplification and 360 ° of rotations, the utility model changes the kind of drive, adopts product ring-shaped guide rail ripe on market and slide block.By driving slide block, slide block is moved on ring-shaped guide rail, thus realizes x, the movement in y, z direction and rotation, and z-axis aspect can 360 ° of rotations.
The method that its technical problem of this practicality solution adopts is: first have employed product circular orbit ripe on market and slide block assembly, rail module directly and upper table surface fix, servomotor is fixed on slide block assembly, motor shaft is provided with gear, engage with ring-shaped guide rail inner tines, move in orbit to drive slide block to realize controlling servomotor.Lower platform and ground are fixed, and platform is provided with 6 cross-garnet butts, each slide block assembly is also provided with cross-garnet butt, lower platform and slide block assembly are coupled together by support bar.When motor rotates with identical speed, 6 slide block assemblies rotate around ring-shaped guide rail with identical speed,
Owing to being connect with rigid rod between two cross-garnet butts, slide block is relatively fixing, and under reaction force, ring-shaped guide rail rotates with upper mounting plate, and can 360 ° of rotations.
Because the circular orbit product on market can be accomplished very little, and the appearance and size of this example is directly related with the appearance and size sliding guide rail, and therefore, this example can realize miniaturization.
Accompanying drawing explanation
Fig. 1 annular six degree of freedom platform
1. upper mounting plates in figure, 2. drive unit (slide block assembly), 3. goes up cross chain, 4. cramp bar, 5. descends cross-garnet butt, 6. lower platform.
Fig. 2 drive unit and track
7. gears, 8. slide block, 9. ring-shaped guide rail, 10. support roller in figure, 11. servomotors.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
In fig. 2, two support rollers (10) are fixed on slide block (8) by screw thread, gear (7) is arranged on servomotor (11), motor assembly is fixed on slide block (8), inner hex screw is fastening by it, form drive unit general assembly, run by spur roller gear, so largely simplify drives structure.
In FIG, upper mounting plate (1) and drive unit (2) are fastened and connected by gear and roller, and upper cross-garnet butt (3) is fixed on drive unit (2) bottom by soket head cap screw, form upper mounting plate general assembly; Lower platform (6) and lower cross-garnet butt (5), by soket head cap screw portion fixed thereon, form lower platform general assembly; Finally by support bar (4), upper mounting plate general assembly is connected with lower platform general assembly with fixing.So relatively, connect upper and lower platform by electric cylinder, structure simplifies a lot, and amount of parts decreases a lot, has innovated the connection of platform, is a kind of well connected mode.
Claims (2)
1. one kind can 360 ° rotate six degree of freedom platforms, in platform jockey, be linked in sequence according to upper mounting plate, drive unit, upper cross chain, support bar, lower cross-garnet butt and lower platform, it is characterized in that: the circular orbit of upper mounting plate is connected with drive unit, upper round hinge bottom drive unit is connected with support bar, the support bar other end is connected with the lower circular hinges on lower platform, simplifies connected mode.
2. according to claim 1 a kind of can 360 ° rotate six degree of freedom platforms, it is characterized in that: drive unit is connected with the circular orbit of upper mounting plate, the mechanical part of drive unit is made up of load bearing seat, roller, gear and servomotor, by servomotor driven gear, gear moves in orbit, change its run location, thus change the position of support bar two-end-point, when six drive units move simultaneously, the locus of six roots of sensation support bar will change, and so just can realize six degree of freedom platform property.
