Abstract
The invention relates to double-rectangular closed static pressure guide rails with high precision and high rigidity, which comprise a feeding direction guide block, a base, static pressure guide rails, capillary throttling devices and a body shell. The double-rectangular closed static pressure guide rails are characterized in that: the feeding direction guide block is fixedly arranged in the middle of the base, and two vertical direction guide blocks are fixedly arranged on two sides of the base respectively; the two static pressure guide rails are fixedly arranged on two sides of the lower end of the body shell respectively; the two static pressure guide rails, the vertical direction guide blocks and the feeding direction guide block form vertical and feeding direction static pressure oil cavities; and the vertical and feeding direction static pressure oil cavities are connected with the upper cavity, lower cavity and feeding cavity capillary throttling devices arranged at the oil inlet of the body shell respectively. The feeding precision and the rigidity of the guide rails are improved, the installation and the debugging of the guide rails are convenient, and trace feeding requirement of 20 millimeters per minute and high rigidity requirement of 200kgf/mu are met.
Description
Technical field
The present invention relates to a kind of feeding grinder hydrostatic slideway, especially a kind of closed-type double action crank press rectangular hydrostatic guide rail.
Background technology
The machine tool feeding guide rail mostly is open type static pressure guide rail or roller guide in the prior art, and its feed accuracy is low, and rigidity is low, and state labile in the time of grinding makes grinding surface quality, feeding resolution ratio relatively poor.
Summary of the invention
The present invention will provide a kind of high precision high rigidity double square closed hydrostatic slideway, and this hydrostatic slideway adopts the closed type static pressure technology, improves feed accuracy and rigidity, makes surface quality of workpieces and parts size precision improve greatly.
Technical scheme of the present invention is: a kind of high precision high rigidity double square closed hydrostatic slideway, comprise the direction of feed guide pad, base, hydrostatic slideway, capillary restrictor, the body shell, be characterized in: the direction of feed guide pad is fixedly mounted in the middle of the base, two above-below direction guide pads are fixedly mounted on respectively on the base both sides, article two, hydrostatic slideway is fixedly mounted on respectively on two sides of body shell lower end, and form with above-below direction guide pad and direction of feed guide pad, descend and direction of feed static pressure oil pocket, on, following and direction of feed static pressure oil pocket is mounted on the epicoele at body shell oil-in place respectively, cavity of resorption, feeding chamber capillary restrictor.
Compared with the prior art, patent of the present invention has following characteristics:
1. adopt capillary restrictor to carry out the oil pressure throttling.
2. adopt closed hydrostatic slideway version.
3. guide rail all adopts the rectangular guideway form.
4. floatation volume is 0.028 ~ 0.032mm between each hydrostatic slideway.
5. guide rail oil pocket form is 12 static pressure chambeies.
6. each static pressure chamber is furnished with the throttling respectively of independent flow controller separately, is convenient to adjust.
Because above-mentioned several respects, the present invention has improved the feed accuracy of this guide rail and rigidity and has been convenient to the Installation and Debugging of this guide rail, has reached the high rigidity requirement of microfeed and the 200kgf/ μ of 20mm/min.
