Description
Technical field
The utility model relates to the precision control and the drive unit of a kind of micron, nanometer motion state and stroke, specifically is a kind of Mebrane And Seal Ring Integrated Push-rod Type Leakage-free Open-loop Hydraulic System.
Background technique
All need adopt micron or nanometer motion working platform to carry out the precision control and the accurate control of stroke of motion state in fields such as bioengineering, medical science, agricultural, industry, military project, scientific researches.Can adopt generally that traditional oil hydraulic cylinder mode, machinery type or piezoelectric constant are little to drive control.Because traditional oil hydraulic cylinder mode is because surface friction drag is big, component machining accuracy height can't realize that micron or nanometer motion working platform carry out the precision control and the accurate control of stroke of motion state.At present, mostly adopt machinery type control.Machinery type is because the Transmitted chains complex structure must cause the huge of mechanism, require high (as biology, medical science, scientific research, military project) field just can't carry out in some bulk, simultaneously in order to reduce cumulative error, zero, the component processing required precision is high, can't realize that micron or nanometer motion working platform carry out the precision control of motion state and the precision control of stroke.The little drive controlling of piezoelectric constant has the high characteristics of control accuracy, but the motion control stroke is very little, and piezoelectric constant easily punctures, thereby its application area is restricted.
Summary of the invention
The purpose of this utility model provides a kind of Mebrane And Seal Ring Integrated Push-rod Type Leakage-free Open-loop Hydraulic System, is used for the precision control and the driving of micron or nanometer motion state and stroke.
The utility model is achieved by the following technical solution: a kind of Mebrane And Seal Ring Integrated Push-rod Type Leakage-free Open-loop Hydraulic System, comprise actuator and control mechanism, and actuator is identical with the control mechanism structure, connects by oil pipe; There are cylinder body, cylinder cap in actuator, be provided with integrated diaphragm at inner chamber of cylinder block, integrated diaphragm comprises flexible membrane that can fold and the seal ring that matches with the inner chamber of cylinder block size, diaphragm is uncovered barrel-shaped of an end, diaphragm and seal ring are integral, and push rod one end is pressed close to the bottom of diaphragm and inserted inner chamber of cylinder block and can do fore and aft motion in inner chamber of cylinder block.
Seal ring in the described integrated diaphragm is the seal ring of O type circle or rectangular loop or wave-shaped ring and similar sealing configuration form.
The utility model is by the isolation between diaphragm realization flowing medium, by realizing fluid-tight with the integrated seal ring that is connected of diaphragm, injection and output by the fluid chamber fluid, under the acting in conjunction of diaphragm and push rod and push rod pre-applied force system, diaphragm produces folding mobile and directed the moving of drive push rod work of individual layer.Thereby realize the accurate control of working platform motion state and stroke.
Good effect of the present utility model is:
1, the utility model does not have the contact friction of the piston and the seal arrangement of conventional cylinder, so resistance to motion is minimum.Because the gap of no piston and seal arrangement exists, no flowing medium leakage phenomenon produces, so can realize accurate control of the motion state of diaphragm and push rod and the accurate control of stroke.
2, the utility model can change the accurate control accuracy of motion state and the accurate control accuracy of stroke of diaphragm and push rod by the ratio of change actuator with control mechanism diaphragm work area.
3, the utility model is owing to adopt open-loop design, and no flowing medium shunting is so can realize accurate control of the motion state of diaphragm and push rod and the accurate control of stroke.
4, the utility model is owing to adopt the integrated push-rod type non-leakage form of diaphragm-seal ring, the radial dimension of reduction system to greatest extent, optimized, simplified the design process of system to greatest extent, reduce the required precision of system zero parts, optimized, simplified processing, assembly technology to greatest extent.
5, the utility model is owing to adopt diaphragm.The integrated push-rod type non-leakage form of seal ring, the change attitude is sealed into static sealing, has realized that the nothing of whole system is leaked.Thereby make working state of system stable, non-maintaining, more energy-conserving and environment-protective.
