Machine, automatically control, accurate measurement, accurate device micro manufacturing, the technical field such as Ultra-precision Turning is to the driving skill of microminiature machinery
The demand of art is increasing.As the core of micro-move device technology, micro-move device technology turns into Jiao of concern under this demand
Point.Traditional precision actuation is mainly using mechanically, and such as precision lead screw is secondary and rolls rail plate, precision auger cotter mechanism,
But due to there are problems that gap, rub, its precision be difficult meet require, develop under these conditions many new
Type of drive, such as electrostatic attraction, electromagnetic type, magnetostriction type, marmem formula and piezoelectric type.
The operation principle of Piezoelectric Driving is mainly the inverse piezoelectric effect of application piezoelectric, i.e., when piezoelectrics are by electric field action
When can produce deformation, have the advantages that compared with other modes electromechanical transformation ratio it is high, without electromagnetic interference, fast response time, and
Flexible piezoelectric fiber is may be used on curved-surface structure, is had broad application prospects in terms of novel intelligent material.
Another aspect inertia-type Piexoelectric actuator is because it is in impulse stroke, resolution ratio, working frequency, movement velocity, frequency
Rate response, manufacturing cost, by having unique advantage in terms of the stagnant ring draw degree of piezoelectric element, have been developed as pressure
One pith of electric precision actuation.Believed more than existing piezoelectric inertia drive device using Asymmetric Electric signal as excitation
Number, but this drive device has the shortcomings that signal is not easy to generation, mechanism and is not easily controlled, has the larger motion that retracts.In view of mesh
The problems of preceding piezoelectric inertia drive device, the present invention proposes a kind of inertia jump Piezoelectric Driving dress based on flexible hinge
Put, by the frictional force between control device and contact surface, Piexoelectric actuator is produced directed movement.With simple in construction, easy
In realizing, device reliability is high, is easy to produce without electromagnetic interference, pumping signal and controls, the advantages of device controllability is good.
The content of the invention
The technical problem of solution is required for of the invention：Under electric signal excitation, piezoelectric fabric 1 (3), piezoelectric fabric 2 (6)
Elongation strain simultaneously, driving metallic plate 1 (2) drives mass (1) to swing, and the inertial impact force produced using mass (1) is real
The overall motion of existing device.
In order to solve the above technical problems, the technical solution adopted in the present invention is：
Described piezoelectric fabric is in parallel mutually Nian Jie using conducting resinl with metallic plate.
Described metallic plate is needed to process certain radian, so as to make it have more preferable mechanical property, end is processed into
Threaded post is so as to quality of connection block and flexure hinge mechanism.Mass (1) has corresponding screwed hole simultaneously.
Connection piezoelectric fabric in the middle part of described metallic plate 1 (2), upper end quality of connection block (1), lower end connection flexible hinge machine
Structure.
Piezoelectric fabric 1 (3), piezoelectric fabric 2 (6) extend generation deformation in the presence of pumping signal, drive metallic plate 1
(2) drive mass (1) to swing to the right, reverse electric signal is inputted thereafter, piezoelectric fabric 1 (3), piezoelectric fabric 2 (6), which shrink, to be become
Shape, produces gap between metallic plate 2 (7) and ground, mass (1) obtains speed to the left, under effect of inertia device it is overall to
Left jump moves a step.
Inertia jump Piexoelectric actuator of the present invention based on flexible hinge passes through metallic plate and piezoelectric fabric phase
The design of bonding, using balancing waveform electric signal encourage, effectively reduce the complexity of structure, overcome device do not allow it is easily-controllable
The shortcoming of system, has reached the purpose of device orient motion；Flexure hinge mechanism is increasing mass (1) as the bottom of device
While stroke, the effect of adjusting means center of gravity is served, the controllability of device motion is improved.
