Description
Technical field
The present invention relates to frock clamp field, and in particular to large-scale workpiece clamping device and grasping system.
Background technology
With developing rapidly for Scientific Industries technology, industrial manufacturing technology achieves revolutionary breakthrough, corresponding processing
The clamping process of the stronger and stronger but matched workpiece of equipment performance such as manufacture, detection, experiment or parts fails to obtain
Adaptable progress, with the implementation of all kinds of heavy constructions, large parts and the overall processing of part, detection, movement, fixation
Become increasingly conspicuous Deng clamping demand, existing clamping workpiece mode is difficult to fully meet requirement.For example in whole large cylinder work
When part clamping, fixation, movement, lifting, integral-rotation etc. are required, there is many common problems：Operation inconvenience, very flexible lacks
Weary safety-type, low precision, cost is high, and efficiency is low；Can for the local method of clamping that some workpiece surfaces have local crowning
Workpiece surface can be caused to damage, or there is uneven clamping dynamics, clamping face and workpiece surface and the feelings of relative displacement occur
Condition；In order to solve such problem, it is necessary to carry out in-depth study exploration.
The content of the invention
For the deficiency in the presence of prior art, realize that what is uniformly clamped is suitable to volume, again the invention provides a kind of
Measure the clamping device that larger cylindrical workpiece is used and the large-scale workpiece grasping system that can flexibly use.
To achieve the above object, present invention employs following technical scheme：
Large-scale workpiece clamping device, comprising circular chuck body, mounting groove is provided with the inner ring of chuck body, to install
Some groups of dismountable grip units；Chuck body is in the outer ring side of its annulus or is additionally provided with for engaging biography with outer gear
Dynamic driving cog；The grip unit includes clamping performs device and grasping drive unit, and grasping drive unit is performed with clamping
Device is connected, for driving clamping performs device in the axially and/or radially motion of chuck body annulus；Each clamping performs device
Circumferentially it is distributed along the inner ring of chuck body.
Further, the chuck body is provided with the outer ring side of its annulus is used for the biography with outer gear engaged transmission
Dynamic tooth.
The present invention is also carried except a kind of large-scale workpiece grasping system, comprising above-mentioned large-scale workpiece clamping device, also comprising holding
Carrying platform, support base is arranged with parallel in carrying platform；The support base is provided with the rolling matched with the outer rim of chuck body
Dynamic support groove.
Further, guide rail rack is provided with carrying platform, accordingly, handwheel and transmission are provided with support base
Portion；The output of handwheel is connected with driving section, and what driving section was output as matching with rack leads moving gear, is passed with passing through handwheel driving
Support base is moved along guide rail rack in dynamic portion.
Design of the invention by multiple grip units, each grip unit can independently drive corresponding clamping to perform dress
Put；After setting constant output or constant output power, each grasping drive unit actively clamps dynamics equilibrium to workpiece, from
And bigger clamping dynamics can be realized on the whole, it is to avoid to the local damage of workpiece surface；And for the workpiece post of not rounded
When body structure or the workpiece interface center of circle are not in chuck body shaft core position, the situation that each grasping drive unit is exported in constant force
It is lower that driving is clamped into performs device to workpiece surface, and to be offseted to amount of stress, in rotary course, grasping drive unit
Being rotated by bottom to top also can adaptively adjust clamping, so as to realize floating clamping, and keep workpiece and bite not to occur
Relative displacement；When the grip unit quantity being distributed in whole circumference is more, effective contact surface during Workpiece clamping can be increased
Product, reduces the chucking power and required spatial volume and weight of single bite, in addition, the other grip unit of dismounting is not yet
Influence can be produced on clamping device on the clamp position of workpiece, the shape knot for occurring interfering with clamping face to cylindrical workpiece surface
Carry out accommodation that can be convenient, flexible during structure.
Compared to prior art, the present invention has the advantages that：
(1) clamping of floating, is realized, the center of workpiece need not be adjusted repeatedly in clamping workpiece, it is not required that extra
Workpiece structure of assistant support or system, improve clamping efficiency；
(2), balanced clamping is realized, clamping workpiece is more stable；
(3), can quantified controlling be clamped the critical pressure of workpiece surface clamping point；
(4), it is prevented effectively from workpiece and is clamped interference of the region local crowning to grasping system；
(5), the safety coefficient during piece-holder is improved；
(6), the clamping suitable for the nearly cylindrical workpiece of a variety of different-diameters.
