Abstract
The present invention relates to a kind of levelling device, especially a kind of levelling device of article carrying platform.Its technical solution is: the present invention includes base, described base is provided with the rotation levelling device, the rotation levelling device comprise can lifting on base the leveling leading screw and the handwheel of rotatable leveling leading screw.It has solved that stroke that the levelling device in the ordinary skill exists is little, load is little, poor stability and precision low technical problem, the characteristics of have that suitable load and velocity range are wide, compact structure, efficient height, reliable operation and life-span being grown.
Description
One, technical field
The present invention relates to a kind of levelling device, especially a kind of levelling device of article carrying platform.
Two, background technique
Present levelling device all is made up of single shaft or 3 pull-rod type devices, and there is following shortcoming in the levelling device of these two kinds of structures:
1, lifting travel is little, load is little.Because the bearing capacity of single shaft or 3 pull-rod type devices is limited, so the levelling device of this structure is subjected to the restriction of bearing capacity, when lifting travel becomes big, top-heavy phenomenon can occur, so its load is little.
2, little, the poor stability of suitable environment.Levelling device is as adopting the single shaft leveling, and it is not suitable for being placed on broken terrain work, and the environment narrow limitation of leveling is big.As adopting 3 pull-rod type devices, its leveling stability is poor again.
3, precision is low.Because the levelling device of this structure adopts single shaft or 3 pull-rod type liftings, the levelling gear of its single shaft or 3 pull-rod type devices can't guarantee the high-precision leveling requirement of levelling device.
Three, summary of the invention
The invention solves that the stroke that the levelling device in the background technique exists is little, load is little, poor stability and the low technical problem of precision.
Technical solution of the present invention is: the present invention is a kind of levelling device of article carrying platform, comprise base, its special way is: described base is provided with the rotation levelling device, the rotation levelling device comprise can lifting on base the leveling leading screw and the handwheel of rotatable leveling leading screw.
Above-mentioned leveling leading screw bottom is provided with the downward modulation flat seat, and leveling leading screw bottom is provided with circular protrusions, on the downward modulation flat seat symmetry have can with the nested circular hole that cooperates of circular protrusions.
Above-mentioned downward modulation flat seat top is provided with and can carries out spacing rise flat seat to the leveling leading screw.
Above-mentioned leveling leading screw is arranged on the base by axle sleeve.
Above-mentioned rotation levelling device is a group or more.
Above-mentioned rotation levelling device is three groups.
Above-mentioned rotation levelling device becomes the center to be symmetricly set on the base.
The present invention has the following advantages:
1, stroke is big, load is big.Because the present invention adopts supported at three point to keep equilibrium principle, that is: utilize the downward modulation flat seat to do support, adopt three groups of leveling handwheels to drive the parallel adjusting lifting distance of leveling leading screw, so its carrying is big, stroke is big.
2, good stability.The present invention by three groups of leveling handwheels drive the leveling leading screws carry out parallel lifting apart from transmission, the bottom is provided with the leveling seat, it can enough guarantee the present invention's stability in the horizontal direction, need not to carry out horizontal leveling once more at horizontal plane, and is easy to operate.
3, precision height.The present invention can guarantee the synchronism of multiple spot lifting, the synchronization accuracy height, and object table parallelism error maximum can be no more than 0.1mm..The instrument leveling error that carries on the object table can be limited in 30 seconds.
4, wide, the compact structure of load of Shi Yonging and velocity range, efficient height, reliable operation and life-span are long.
Four, description of drawings
Accompanying drawing is a structural representation of the present invention.
Five, embodiment
Referring to accompanying drawing, the present invention includes the rotation levelling device, axle sleeve 3 and base 4, the rotation levelling device comprises handwheel 1, leveling leading screw 2, raise flat seat 5, downward modulation flat seat 6, leveling screw mandrel 2 is arranged on the base 4 by axle sleeve 3, axle sleeve 3 by screw on base 4, raise flat seat 5, downward modulation flat seat 6 is arranged on the leveling leading screw 2, leveling leading screw 2 bottoms are provided with circular protrusions 7, the downward modulation flat seat 6 on the symmetry have can with the circular protrusions 7 nested circular holes that cooperate 8, during 2 liftings of leveling leading screw, circular protrusions 7 is rotated in circular hole 8, can guarantee the centralized positioning in the lifting process of leveling leading screw 2, has guaranteed the stability of lifting of the present invention.The rotation levelling device is good with 3, and each rotation levelling device becomes the center to be symmetrical arranged on the base 4, and leveling of the present invention is highly decided on the length of leveling leading screw 2.
When the present invention works, driving leveling screw mandrel 2 by three groups of handwheels 1 rotates, following leveling seat 6 is done jack-up support, and leveling leading screw 2 circular protrusions 7 are rotated around the arc center, garden of reducing the circular hole 8 on the flat seat 6, raises flat seat 5 and plays position-limiting action by screw on downward modulation flat seat 6.
