At present, hydrostatic slideway is widely used in ultra-precision machine tool, and hydrostatic slideway exists multiple oil pocket, realizes guide rail carrying by the pressure difference of upper lower oil cavitie.Hydrostatic slideway adopts level pressure oil supply system, namely with the oil pump that a delivery pressure remains unchanged substantially, realizes the system of fuel feeding to all oil pockets of hydrostatic slideway simultaneously.Therefore each oil pocket must be connected a flow controller, and hydrostatic slideway just has bearing capacity.
The structural type of flow controller can be divided into two classes by working principle: fixed restriction device and variable throttler.Fixed restriction device is divided into again orifice restriction device, capillary restrictor, gap flow controller etc.The hydrostatic slideway related in the present invention need carry more than 200kg, and orifice restriction device, gap flow controller exist, and load-carrying is little, the more high defect of machining accuracy.So hydrostatic slideway all adopts capillary restrictor mostly.
Capillary restrictor is divided into again straight-through type and spiral groove type.Straight-through type capillary restrictor is commonly used medication injections needle tubing and is made, and selects suitable inner diameter and length to be welded on joint as required.Spiral groove type flow controller opens spiral chute on periphery, then with housing inner diameter by Spielpassung, form asphalt channel.This form structure is compact, but processing request is higher.So this hydrostatic slideway adopts straight-through type capillary restrictor.But there is many defects in existing straight-through type capillary restrictor: 1. complex structure, mounting or dismounting trouble; 2. capillary pipe length is non-adjustable, causes Throttling ratio non-adjustable; 3. machining accuracy and quality of fit require also higher; 4. existing straight-through type capillary restrictor go out oil pocket oil pressure can not detect or detecting method complicated.
Summary of the invention
For solving the problem, the invention provides that a kind of structure is simple, mounting or dismounting are convenient, can be as required, any adjustment capillary pipe length, processing is simple, and cost is little, go out oil pocket oil pressure easy to detect, can real-time online detect easy tune easy altimetry precision enclosed constant voltage hydrostatic slideway flow controller.
The technical solution adopted for the present invention to solve the technical problems is: the easy altimetry precision enclosed constant voltage hydrostatic slideway flow controller of a kind of easily tune, comprise housing and core body, be provided with oil suction chamber in described housing and go out oil pocket, described housing is provided with respectively with oil suction chamber with go out the core body installation position that oil pocket crosses, described core body is contained in described core body installation position, described core body is provided with oil suction chamber described in conducting and goes out the throttling oil circuit of oil pocket, described core body the outlet of throttling oil circuit be connected with stretch into described in go out capillary tube in oil pocket.
Be further used as the improvement of technical solution of the present invention, be provided with in described core body with described go out the detection oil circuit that is communicated with of oil pocket, described detection oil circuit is formed in the end face outside of core body and detects mouth, and removable plug is equipped with at described detection mouth place.
Be further used as the improvement of technical solution of the present invention, described plug comprises fastening screw trip bolt and the O type circle be sleeved on described fastening screw trip bolt and pad.
Be further used as the improvement of technical solution of the present invention, described core body forms circular groove in oil suction chamber, described detection oil circuit is the through hole drilling through core body inner side end and end face outside, and described throttling oil circuit comprises and is parallel to described through hole by the inner side end of core body and is drilled into the parallel hole in the middle part of circular groove and is drilled into the upright opening of parallel hole by described circular groove perpendicular to through hole and parallel hole place plane.
Be further used as the improvement of technical solution of the present invention, described core body installation position is the mounting hole being located at described housing one side end face, described mounting hole comprises and extends to the outer section of described oil suction chamber by housing end face and extended to out the inner segment of oil pocket by oil suction chamber, the inner segment of described mounting hole and go out forming station terrace between oil pocket, described core body is threaded with the inner segment of mounting hole and and between step surface, seal ring is housed.
Be further used as the improvement of technical solution of the present invention, described housing is provided with mounting groove outside the outer section of mounting hole, described core body at described mounting groove built with sealing gasket and tightening nut.
Be further used as the improvement of technical solution of the present invention, firm by epoxy bond between described capillary tube and core body.
Beneficial effect of the present invention: easily the easy altimetry precision enclosed constant voltage hydrostatic slideway flow controller of tune can directly using guide rail as housing for this, on housing shaping be connected with guide rail oil pocket and oil supply system respectively go out oil pocket and oil suction chamber, and the core body installation position of core body is installed, during use, fluid flows into oil suction chamber by oil supply system, and then the throttling oil circuit again on core body enters out oil pocket by capillary tube, realizes throttling.Structure of the present invention is simple, mounting or dismounting are convenient, as required, can regulate capillary pipe length arbitrarily, and processing is simple, and cost is little.And, owing to directly arranging the detection oil circuit for detecting oil pocket oil pressure on core body, going out oil pocket oil pressure easy to detect, can detect by real-time online.
