Description
Technical field
The utility model relates to the ultra precise workbench field, is specially the ultra precise workbench that comprises gas suspension and Electromagnetic Drive.
Background technology
In fields such as semiconductor lithography, micromachine, accurate measurement, ultraprecise processing, miniature assembling, biological cell manipulation and nanometer technologies; Need very accurate localization and very fine motion, therefore high performance ultraprecise positioning table becomes the technical support in these fields.Realize sub-micron even nano level location, the conventional driving and the kind of drive are no longer suitable.Such as, in order to realize conventional precision positioning, often adopt the scheme of driven by servomotor and precision lead screw transmission usually, yet this kind locate mode because the existence of screw thread idle running and gearing friction, its positioning accuracy generally can only reach micron order.Therefore, seek the special driving and the kind of drive, become necessary so that workbench is realized sub-micron even nano level motion positions.
Air bearing is to utilize the viscosity of air; The fully dry back of also filtering of the compressed air of outside is imported in the air bearing gap through some flow controllers of opening on bearing surface; Make between the working face of air bearing to have constrictive air abrim, and come support load and realize steadily action by the pressure air film that forms.Little because of its frictional resistance, wear rate is almost equal to zero, noise is low, vibrations are little, motion is steady, precision is high, and by successful Application in many fields.According to the principle that pressure produces, gas bearing generally is divided into three kinds on dynamic pressure type, hydrostatic profile and pressing mold type, and at present widely used is dynamic pressure type and hydrostatic profile.Air-float guide rail belongs to pressure-feed air bearing, in the Precision Linear Moving system, has a wide range of applications.The air-float guide rails that adopt in big stroke precision stage, the sliding pair that air-float guide rail is made up of guide rail and slide block is gas film lubrication between guide rail and the slide block more.Air-float guide rail has does not in the course of the work has directly contact, frictional damping is little and approximately constant, characteristics such as operating temperature range is wide, adaptive capacity to environment is strong, precision is high, the life-span is long, so is widely used in the guide track system of ultra precise measurement and micro-nano process unit.Yet air-float guide rail has a shortcoming, and promptly the too small kinergety that causes of damping can't in time decay in motion process, causes bigger energy to pass to other structure member, thereby quotes distortion and vibration.
