Technical field
The present invention relates to Actuator technique field, and in particular to the Inchworm type actuator of a kind of piezoelectricity crude fibre and piezoelectric pile
And start method.
Background technology
Piezoelectricity crude fibre composite-MFC (Macro fiber composite) is a kind of new piezoelectric ceramics material
Material, compared to traditional piezoelectric ceramics, MFC is more soft, durable, reliable and is easy to surface mount, can produce big deformation, and
Light weight, thickness of thin, quality and rigidity to structure have little to no effect.Its unique electrode and piezoelectric fabric are arranged such that it
Possess higher piezoelectric modulus and electromechanical coupling factor, bigger be used as power can be produced.
The piezoelectric type actuator made based on inverse piezoelectric effect have high resolution, High power output, response fast, small power consumption,
The advantages of structure is light.Therefore, all kinds of actuator of piezoelectric have been widely used in machinery, ship, automobile, building, boat
The numerous areas such as empty space flight, as one of current most widely used intelligent drives device.
Because piezoelectric output displacement is micro-displacement, Inchworm type start is realized, is typically made using multiple piezoelectric piles
The constraint of dynamic and clamper, and complicated, heaviness.If it is desired to Inchworm type power output and displacement, while having power-off clamper, softness resistance to
During with, the function such as small volume, light weight, conventional piezoelectric class Inchworm type actuator etc. is difficult to meet above-mentioned all conditions.
The content of the invention
In order to solve the problem of above-mentioned prior art is present, it is an object of the invention to provide a kind of piezoelectricity crude fibre and pressure
The Inchworm type actuator of pile, with the features such as clamper, light structure, quick start is powered off, realizes two-way Inchworm type start
Function.
In order to achieve the above object, the present invention is adopted the following technical scheme that:
Piezoelectricity is pasted with the Inchworm type actuator of a kind of piezoelectricity crude fibre and piezoelectric pile, including arc 4, arc 4
Crude fibre 5, the two ends of arc 4 are connected with the first rhombus ring 2 and the second rhombus ring 6 respectively by pin 8;The first rhombus ring
2 and the long between centers of the second rhombus ring 6 place the first piezoelectric pile 3 and the second piezoelectric pile 7 respectively;First piezoelectric pile 3 and second is pressed
When pile 7 is not powered on, the first rhombus ring 2 and the short axle two ends of the second rhombus ring 6 are in close contact with external frame 1, in clamper shape
State.
The external frame 1 and the first rhombus ring 2 and the short axle contact surface of the second rhombus ring 6 are coarse, quiet to rub in clamping state
Wipe power big.
The original shape of arc 4 is arc-shaped thin plate, and surface mount piezoelectricity crude fibre 5 is promoted using alite paste 7649
Enter agent and 326 structure glues.
External frame 1 is thin-slab structure.
The Inchworm type actuator of the piezoelectricity crude fibre and piezoelectric pile, when being not powered on, the first rhombus ring 2 and the second rhombus ring
6 clampers are in external frame 1;When starting start, first the first piezoelectric pile 3 is powered, the first piezoelectric pile 3 extends, the first rhombus ring 2 is short
Axle shortens, and releases clamper constraint;Piezoelectricity crude fibre 5 is powered again, arc 4 is bent;Then the first piezoelectric pile 3 is powered off, then
Second piezoelectric pile 7 is powered, then the clamper of the first rhombus ring 2, the second rhombus ring 6 releases the clamper constraint with external frame 1;Finally
Piezoelectricity crude fibre 5 is powered off, the bending position shape of arc 4 is recovered, and promotes the second rhombus ring 6 to be moved to side;If releasing clamper about
The order of beam is on the contrary, then move backward;By lasting switching electricity, two-way Inchworm type power output and displacement are realized with this.
Compared to the prior art the present invention, has the following advantages that:
1) when the first piezoelectric pile 3 and the second piezoelectric pile 7 of actuator are not powered on, the first rhombus ring 2 and the second rhombus ring 6 with
The clamper of external frame 1 is constrained, that is, the characteristics of having power-off clamper.
2) compared to conventional piezoelectric class Inchworm type actuator, the Inchworm type actuator of piezoelectricity crude fibre and piezoelectric pile is using pressure
Electric crude fibre 5 realizes elongation 103Ppm grades of starts.Arc 4 is the big material of deflection, and work is bent in piezoelectricity crude fibre 5
During pattern, there is bigger displacement deformation.
3) actuator is realized in the range of the bidirectional output of piezoelectricity crude fibre 5 by the first piezoelectric pile 3 and the second piezoelectric pile 7
The clamper constraint of optional position.
4) original shape of arc 4 of actuator is arc-shaped thin plate, and external frame 1 is also thin-slab structure, mitigates structure
Weight.
5) when the piezoelectricity crude fibre 5 of actuator is pasted, using 7649 accelerator and 326 structure glues, sticking effect is good.
In a word, the shortcomings of present invention can avoid conventional piezoelectric class Inchworm type actuator configurations complicated, with power-off clamper,
The advantages of soft durable, light structure.
