Abstract
The invention discloses a kind of based on corrugated sheets without piston-cylinder, and structure includes: including corrugated sheets, cylinder body, reset spring, piston rod.Wherein corrugated sheets include the non-ripple border circular areas two parts in annular corrugated region and center, and annular corrugated area outer diameter is connected on cylinder body, and the non-ripple border circular areas in center is connect with piston rod, and reset spring is connect with piston rod and cylinder body respectively.Its processing technology is simple, precise structure, small in size, light-weight, good airproof performance, is not easy to reveal, is at low cost, suitable for the stroke occasion of small stroke in the micron-scale.It can work in the case where rigidity is without friction " No leakage ", cylinder be reflected under any state sensitive, movement is steady, and without creeping phenomenon in low-speed motion.
Description
Technical field
The present invention relates to the taut film device fields for heavy caliber thin membrance mirror, specifically propose a kind of sinusoidal for small stroke
Shape corrugated sheets cylinder.
Background technique
Cylinder has energy saving, pollution-free, efficient, inexpensive, safe and reliable, advantages of simple structure and simple.At present in the world
Developing so-called friction-free air cylinder product has two classes, and one is diaphragm type structures, and one is air-flotation type structures.The latter's piston with
Cylinder barrel is clearance seal and introduces high pressure gas realization gas film lubrication, and the frictional force of the two is only from the viscous force of gas, due to
Air viscosity very little, frictional force are extremely low, so being referred to as without friction devices.But in the prior art, common cylinder is not able to satisfy
Different needs of work, as a result, it is often necessary on the basis of common cylinder, by changing or increasing the part-structure of cylinder,
To develop special air cylinder structure；
Cylinder is component part important in pneumatic system, its performance quality determines that the performance of entire pneumatic system is good
Bad currently, with pneumatics deep development, it is desirable that cylinder should subtract as far as possible under the premise of " No leakage " or " few leakage "
Few frictional force, enables cylinder to reflect under any state sensitive, and movement is steady, and should be without creeping phenomenon in low-speed motion, this
It is that current countries in the world researcher makes great efforts one of project explored；
Convoluted diaphragm, also known as Corrugated Circular Plates are a kind of thin plates for being pressed with concentric corrugations.Strictly, it is a kind of spy
The shell of different shape.In the elastic element of precision instrument, it occupies status extremely outstanding, is not only widely used, Er Qie
It plays the role of a nucleus in instrument structure.The shape of convoluted diaphragm is varied, common are sinusoidal, trapezoidal and zigzag ripple.
Summary of the invention
The object of the present invention is to provide a kind of based on corrugated sheets without piston-cylinder.
Present invention technical solution used for the above purpose is: its structure includes cylinder body (101), corrugated sheets
(102), piston rod (103), reset spring (104), the corrugated sheets include the non-wave in annular corrugated region (201) and center
Line border circular areas (202) two parts, wherein annular corrugated region (201) are connect with cylinder body (101), the non-ripple border circular areas in center
(202) it is connect with piston rod (103), the reset spring (104) is connect with piston rod (103) and cylinder body (101) respectively.
The present invention it is a kind of based on corrugated sheets without piston-cylinder, processing technology is simple, precise structure, small in size, weight
Gently, good airproof performance, be not easy to reveal, be at low cost, suitable for the occasion of stroke in the micron-scale.
The present invention it is a kind of based on corrugated sheets without piston-cylinder, corrugated plate (102) include annular corrugated region (201) and
The non-ripple border circular areas (202) in center；Wherein, the non-ripple border circular areas (201) in center connect with piston rod (103), and the two is adopted
It is press-connected mode with rigidity, when sinusoidal corrugated sheets (102) are by side air pressure pressure, an axial millimeter amount can be generated
Grade microspur, drives piston rod (103) to generate millimeter magnitude microspur；
The present invention it is a kind of based on corrugated sheets without piston-cylinder the advantages of and effect: cylinder is in the case where " No leakage "
Work, it is sensitive that this enables cylinder to reflect under any state, and movement is steady, and should be without creeping phenomenon in low-speed motion.If
This cylinder, under control loop height unanimous circumstances, the fortune of the piston rod (103) of cylinder are driven using parallel control loop
Dynamic state also can be highly consistent；

Specific embodiment
In order to make the objectives, technical solutions, and advantages of the present invention clearer, in conjunction with Fig. 1 and Fig. 2 to the present invention into
Row is further described, but protection scope of the present invention is not limited to following embodiments；
As depicted in figs. 1 and 2, in the state that cylinder body (101) are fixed, a level pressure is filled with to cylinder using air compressor
Strong gas, the annular corrugated region (201) of corrugated sheets (102) generates micron order microspur under the action of pressure, thus band
The dynamic non-ripple border circular areas (202) in center and piston rod (103) generate axial microspur.When cylinder in an inactive state, reset
Corrugated sheets (102) and piston rod (103) are returned to initial position by spring (104)；
The above embodiment is a preferred embodiment of the present invention, but embodiments of the present invention are not by above-described embodiment
Limitation, it is other any without departing from made changes, modifications, substitutions, combinations, simplifications under this hair quality and principle, it should be equivalent
Substitute mode, be included within protection scope that this bright spirit is invented in fact.
