The specific embodiment
Below be specific embodiments of the invention and in conjunction with the accompanying drawings, technical scheme of the present invention is further described, but the present invention be not limited to these embodiment.
As shown in Figure 1, Figure 2, Figure 3 and Figure 4, this oil film static-pressure guide device is made up of guide rail bracket 1, saddle 2 and upper slide rest 3 etc.
Specifically, guide rail bracket 1 is provided with guide rail 1a longitudinally, and guide rail 1a is the capable recessed gathering sill of V, and saddle 2 is arranged on the guide rail 1a and has the shape that is complementary with guide rail 1a, and saddle 2 is realized moving of vertical equity direction on guide rail 1a.Upper slide rest 3 is arranged on the saddle 2, and saddle 2 tops have horizontal swallow-tail form projection, and upper slide rest 3 bottom surfaces have the dovetail groove that matches with the swallow-tail form projection, and upper slide rest 3 is set on the saddle 2 to realize moving of transverse horizontal direction.
Be provided with the hermetically-sealed construction 8 that can prevent that hydraulic oil from overflowing at guide rail bracket 1 place, hermetically-sealed construction 8 comprises sealing strip 8a, be positioned at guide rail 1a end and and the sealing block 8b that is connected of guide rail bracket 1, sealing strip 8a is positioned at the upper end of the guide rail 1a that contacts with saddle 2, is provided with rubber sheet gasketing 8c between guide rail 1a end and sealing block 8b.The setting of sealing strip 8a has prevented that hydraulic oil from overflowing from guide rail 1a upper end, and the setting of sealing block 8b has prevented that hydraulic oil from overflowing from guide rail 1a end, and hydraulic oil can not overflow and other parts of making dirty like this, and the overall sealing performance of this device is good.The setting of rubber sheet gasketing 8c has guaranteed sealing property more.
As shown in Figure 4, saddle 2 is provided with groove 9 with the side that contacts of guide rail 1a, groove 9 UNICOM's oil-through holes 6, and the groove 9 in the present embodiment is fish line cross-like, and oil-through hole 6 is positioned at the infall of groove 9.Groove 9 is oil-through hole 6 UNICOMs, and hydraulic oil can enter groove 9 when oil-through hole 6 flows out, and hydraulic oil is evenly distributed in the side that contacts of saddle 2 and guide rail 1a, the oil film good uniformity that forms between saddle 2 and the guide rail 1a like this.Guarantee originally to have the stability and the precision of oil film static-pressure guide device operation.
As Fig. 3 and shown in Figure 5, the both sides of saddle 2 are provided with L-shaped shackle member 10, shackle member 10 is fixed with the underrun screw that is positioned at the saddle 2 in guide rail bracket 1 outside, and the sidepiece clamping mutually of shackle member 10 and guide rail bracket 1, is provided with tapered gag 11 between the sidepiece of shackle member 10 and guide rail bracket 1.
During work, by hydraulic pump hydraulic oil is entered in the saddle 2 through the fuel feed hole 4 that saddle 2 sidepieces have, hydraulic oil flows out from oil-through hole 6 and the oil outlet 5 that links with fuel feed hole 4 again, the hydraulic oil that flows out from oil-through hole 6 can enter groove 9, hydraulic oil is evenly distributed in the side that contacts of saddle 2 and guide rail 1a, and the hydraulic oil that flows out from oil outlet 5 is positioned at saddle 2 bottoms.Sealing strip 8a has prevented that hydraulic oil from overflowing from guide rail 1a upper end, sealing block 8b and rubber sheet gasketing 8c have prevented that hydraulic oil from overflowing from guide rail 1a end, just formed the layer of even oil film between saddle 2 and the guide rail 1a like this, oil film holds up saddle 2 and the upper slide rest 3 that is arranged on the saddle 2, can realize saddle 2 and upper slide rest 3 moving at guide rail 1a place by common screw mandrel transmission.
When hydraulic oil continues to enter between saddle 2 and the guide rail 1a, saddle 2 exists and can be held up too high problem by oil film, and the setting of shackle member 10 has then limited the lifting height of saddle 2 at guide rail 1a place, makes saddle 2 stable when working; And shackle member 10 has limited the gap between saddle 2 and the guide rail 1a, even have certain clearance between the sidepiece of shackle member 10 and guide rail bracket 1, but this gap has been eliminated in being provided with of tapered gag 11, makes that the thickness of oil film is very little, guarantees the rigidity at guide rail 1a place.Last hydraulic oil can flow into guide rail bracket 1 inner chamber again by the entrance point of hydraulic pump from the spill port 7 of guide rail 1a bottom, and hydraulic pump makes hydraulic oil flow into fuel feed hole 4 again, so just forms the recycling of hydraulic oil.
As shown in Figure 7, present embodiment is basic identical with principle and the structure of embodiment 1, and different place is that the groove 9 in the present embodiment is cross-like in length and breadth, and oil-through hole 6 is positioned at the infall of groove 9.Hydraulic oil enters in the groove 9 from oil-through hole 6 like this, being full of hydraulic oil in the groove 9 makes hydraulic oil evenly be distributed in fully between saddle 2 and the guide rail 1a, determine the uniformity of oil film, guaranteed originally to have the stability and the precision of oil film static-pressure guide device operation.
Specific embodiment described herein only is that the present invention's spirit is illustrated.The technical staff of the technical field of the invention can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present invention or surmount the defined scope of appended claims.
Although this paper has used terms such as guide rail bracket 1, guide rail 1a, saddle 2, upper slide rest 3, fuel feed hole 4, oil outlet 5, oil-through hole 6, spill port 7, hermetically-sealed construction 8, sealing strip 8a, sealing block 8b, rubber sheet gasketing 8c, groove 9, shackle member 10, tapered gag 11 morely, do not get rid of the possibility of using other term.Using these terms only is in order to describe and explain essence of the present invention more easily; They are construed to any additional restriction all is contrary with spirit of the present invention.
