Below parts sign flag explanation of the present invention:
The specific embodiment
For further understanding feature of the present invention, technological means and the specific purposes that reach, function, resolve the advantages and spirit of the present invention, by below in conjunction with accompanying drawing and the specific embodiment, detailed description of the present invention being further understood.
A micromotion platform, comprises base 10 and is located at the workbench 20 on base 10.Workbench 20 is flexibly connected with base 10, can on base 10, move.This workbench 20 is circular, and the top of workbench 20 is transparent.
In workbench 20, be provided with 30, three groups of straight line modules 30 of three groups of straight line modules and be circumference array form and be fixed on base 10, and the angle of every two groups of straight line modules 30 is 60 degree.Three straight line modules 30 operate the force direction producing and form an equilateral triangle.This symmetrical configuration and stable, simple in structure.
This straight line module 30 comprises voice coil motor 31 and the travel mechanism 32 being connected with voice coil motor 31.Voice coil motor 31 is located at base 10Shang， travel mechanism 32 and is connected in workbench 20，Gai travel mechanism 32 for double-deck bearing arrangement, has eliminated gap, and precision is higher.Voice coil motor 31 comprises stator 311 and mover 312, and stator 311 is fixed on base 10, and mover 312 is connected in travel mechanism 32.When voice coil motor 31 work, this mover 312 drives travel mechanism 32 moving linearly back and forth.
On support member 322, offer one first deep-slotted chip breaker, on folder 323, offer the second deep-slotted chip breaker.The first deep-slotted chip breaker is relative with the second deep-slotted chip breaker position, forms an accepting groove 325, and duplex bearing 324 is positioned at described accepting groove 325.Duplex bearing 324 comprises the bearing of two overlapping storings, and the central part of two bearings is penetrated with axle center 326.During assembling, first two bearings is installed on this axle center 326, then by bolt, described folder 323 and support member 322 is locked, can realize the extruding to duplex bearing 324, eliminate gap, realize high accuracy.
