Piezoelectric ceramic is used widely in micrometric displacement driving and precision positioning field with its superior driveability, obtained effect preferably, but on the whole, the displacement of piezoelectric ceramic actuator is generally less than tens microns, for need be aspect the stroke driving more than the displacement of hundreds of micron, just can't directly utilize piezoelectric ceramic actuator to drive, can not give full play to the superior driveability of piezoelectric ceramic, limit its range of application.This just requires further improvement, and amplifies the drive displacement of piezoelectric ceramic is done greatly, satisfies the needs of bigger movement travel.
The utility model content
At the shortcoming of prior art, the purpose of this utility model provides a kind of micrometric displacement amplifying device with the little and compact conformation of bigger displacement multiplication factor, error.
For achieving the above object, the technical solution of the utility model is: a kind of micrometric displacement amplifying device, the displacement amplifying mechanism that comprises pedestal, is located at the piezoelectric ceramic actuator on the pedestal and drives by piezoelectric ceramic actuator, wherein, this displacement amplifying mechanism is connected and is connected in parallel by flexible hinge by some drive rods and forms, and by this displacement amplifying mechanism output displacement.
This displacement amplifying mechanism comprises push rod, push rod, first connecting rod, second connecting rod, pull bar, take-off lever and connects the flexible hinge structure of each bar, this push rod is driven by piezoelectric ceramic actuator, connect with push rod after push rod and the first connecting rod parallel connection, second connecting rod is connected with push rod, pull bar is connected with first connecting rod, connects with the take-off lever of output displacement after second connecting rod and the pull bar parallel connection.
Piezoelectric ceramic actuator contacts with an end of push rod, the other end of push rod is connected with an end of push rod and first connecting rod respectively by flexible hinge, the other end of push rod is connected with an end of second connecting rod by flexible hinge, the other end of first connecting rod is connected with an end of pull bar by flexible hinge, and second connecting rod all is connected with take-off lever by flexible hinge with the other end of pull bar.
Above-mentioned flexible hinge is the revolute pair flexible hinge.
The monolithic construction that each drive rod of displacement amplifying mechanism is connected as one by flexible hinge and pedestal.
Piezoelectric ceramic actuator is installed on the pedestal of displacement amplifying mechanism, and by the screw pretension.
Compared with prior art, the utility model is by multistage series connection of some drive rods and the multistage structure for amplifying that is connected in parallel, adopted differential amplification principle, realize bigger displacement multiplication factor, have bigger stroke, again because drive rod all adopts the syndeton of flexible hinge, make and do not have friction between each drive rod, no gap is so displacement amplifying mechanism can reduce error as much as possible increasing the displacement multiplication factor simultaneously.
In addition, the monolithic construction that the utility model also utilizes each drive rod of displacement amplifying mechanism to be connected as one by flexible hinge and pedestal, displacement amplifying mechanism can be processed by a block of material, make the displacement amplifying mechanism compact conformation, need not assembling, thus the error that produces when having avoided assembling.
