Description
Technical field
The utility model relates to a kind of flexible precisely locating platform, specifically is a kind of the realization along the precision positioning of Z direction and around the flexible precision positioning platform of the meticulous adjustment of angle of X, Y-axis.
Background technology
At present, precisely locating platform does not have the redundant performance of driving.So-called redundant, be exactly to consider a unnecessary amount from security standpoint, this is measured in order to ensure that instrument, equipment or a certain being operated under the improper situation also can run well.When if motion platform is in improper situation, reduce the ability of finishing the work with losing one or several degree of freedom.Therefore, can drive the ability to work that input improves worktable, satisfy the requirement of avoiding near improper situation by increasing by one or several.This redundant precisely locating platform can be optimized operability, improve kinematics and dynamics.In addition, existing three-freedom degree precision locating platform generally all exists input, output coupled problem, thereby has influenced operating accuracy, increases the control difficulty.
Summary of the invention
The purpose of this utility model is at the existing shortcoming of prior art, provide a kind of Three Degree Of Freedom integral type flexible precision positioning platform, but this positioning table can be avoided near improper situation, optimization operational readiness simultaneously, improve kinematics and dynamics, and whole locating platform body is one, can be processed by a block of material.
For achieving the above object, the utility model adopts following technical proposals:
The flexible precisely locating platform of a kind of Three Degree Of Freedom integral type comprises motion platform, pedestal.Be connected by four groups of micro displacement magnifying mechanisms between motion platform and the pedestal; And four groups of micro displacement magnifying mechanisms are 90 ° of cross-distribution between pedestal and motion platform.
Micro displacement magnifying mechanism is by first to fourth member, first to the 8th flexible hinge, and the first, two connecting rod, microdrive constitutes; Microdrive upper surface and the 4th member lower surface bonds are together, the input end of the first structure bar connects microdrive, and first member and the 4th member are by second connecting rod and second, the 3rd flexible hinge connects, first connecting rod and the 4th member are by second member and first, the 5th flexible hinge connects, and the 3rd member connects by the seven, the eight flexible hinge with the first connecting rod and first member respectively.
Micro displacement magnifying mechanism is that differential secondary amplifies or multistage enlarger.
Compared with the prior art, this experiment is novel has a following beneficial effect:
This experiment is novel has adopted four groups to drive input, and locating platform has only three degree of freedom, this redundant drive has increased the operability of locating platform, can satisfy the kinematics requirement, can also enlarge the working range of locating platform by the progression of further increase enlarger; Owing to adopted four groups of flexible hinges, having guaranteed no gap that motion transmits, do not had friction, exempt to lubricate, high precision and high stability; Owing to adopted symmetrical structure, can effectively avoid the coupling effect importing, export, avoid accumulated error, effectively improve the precision of platform; Owing to adopted displacement amplifying mechanism, the stroke of microdrive can be amplified according to multiple, can realize that motion platform is in motion in a big way; Because motion platform and pedestal all are integrated on the one, can process by a block of material, realize exempting from assembling.
The utility model can not only reach nano grade positioning precision, but and the operational readiness of whole locating platform body, kinematics and dynamics can both obtain very big improvement.Redundant precisely locating platform can also enlarge the working range of locating platform when satisfying the kinematics requirement, increase its operation flexibility, effectively overcomes input, output coupled problem.
