The specific embodiment
Below with reference to accompanying drawing the present invention is done concrete explaination.
A kind of ram leak-proof arrangement of the embodiments of the invention as shown in Fig. 1 and Fig. 3 comprises rotary slide base 1, ram 2, ram swab case 3.
Ram swab case 3 is connected with rotary slide base 1, and ram swab case 3 is provided with through hole 31.Ram 2 inserts in rotary slide base 1 and the through hole 31, and can the direction shown in A among the figure and B reciprocatingly slide in the through hole 31 of rotary slide base 1 and ram swab case 3.The sliding surface that contacts with the through hole 31 of rotary slide base 1 and ram swab case 3 on the ram 2 has level and smooth surface.
The through hole 31 of ram swab case 3 is provided with sealing 32.Slipper seal is connected between sealing 32 and the ram 2.Also be provided with oil-containing groove 33 on the ram swab case 3.Side with respect to rotary slide base 1 on oil-containing groove 33 and the sealing 32 communicates.
The ram swab case of the present invention by being tightly connected ram setting prevents that lubricating oil is from landing between ram and rotary slide base.Ram of the present invention has level and smooth surface, and ram swab case and ram around all can be tightly connected, simultaneously, oil-containing groove can conveniently store the lubricating oil that exposes that the ram swab case stops.The present invention is simple in structure, makes fast, and cost is lower, can prevent safely and effectively the generation of leakage of oil situation.
As shown in Figure 2, in an embodiment of the present invention, the cross section of ram 2 is square.Also can be trapezoidal.The surface of smooth ram 2 is beneficial to the best effect that stops leakage of oil of ram swab case 3 performances that is tightly connected with it.And preferred, when moving up and down for ram 2 support required, ram 2 also comprises pillow 21 and guide-rail plate 22, guide-rail plate 22 is located at four jiaos of the foursquare cross section of ram.In the present embodiment, in order to guarantee planarization, the surface of ram 2 needs to process together after installing all guide-rail plates 22 smooth.
As shown in Fig. 3 and Fig. 1, in an embodiment of the present invention, ram swab case 3 through holes 31 be shaped as square.Oil-containing groove 33 be shaped as foursquare annular groove, the opening of annular groove is towards rotary slide base 1.In the present embodiment, the size of through hole 31 is consistent with the cross sectional dimensions of ram 2.Be convenient to the sealing of through hole 31 and ram 2.
In addition, as shown in fig. 1, in an embodiment of the present invention, also comprise and scrape the bits plate.An end of scraping the bits plate is connected with ram 2 slipper seals, and the other end of scraping the bits plate is connected with ram swab case 3.Scrape bits plate comprise first scrape bits plate 4 and second scrape bits plate 5.First scrapes bits plate 4 is located between rotary slide base 1 and the ram swab case 3, and first other end of scraping bits plate 4 is connected with oil-containing groove 33.First scrapes bits plate 4 when ram 2 slides up and down, and the lubricating oil on ram 2 surfaces is scraped, and the lubricating oil that scrapes can directly enter in the oil-containing groove 33 of the ram swab case 3 that is connected with first other end of scraping bits plate 4.
Second scrapes bits plate 5 is located at rotary slide base 1 with respect to the opposite side of ram swab case 3.Be used for preventing that outside iron filings and dust from entering the sliding surface that ram 2 is positioned at ram swab case 3 and rotary slide base 1 inside.
In addition, as shown in Figure 4, in an embodiment of the present invention, scrape the bits plate and be provided with the sealing through hole, be tightly connected in the ram 2 insert-seal through holes and with the sealing through hole.Namely first scrape bits plate 4 and second scrape bits plate 5 shape similar to ram swab case 3.And in order to guarantee the effect of ram leak-proof arrangement of the present invention, first scrapes bits plate 4 and second, and to scrape bits plate 5 must be one-body molded, can guarantee so can not occur the tradition splicing and scrape the situation that the lubricating oil of bits plate spills from the slit.
As shown in Fig. 3 and 1, in an embodiment of the present invention, sealing 32 is provided with seal groove 34 and sealing ring 35.Sealing ring 35 is located in the seal groove 34, and sealing ring 35 is tightly connected with ram 2.Sealing ring 35 can be strengthened the sealing 32 of ram swab case 3 and the sealing effectiveness of ram 2.
In the present embodiment, sealing ring 35 adopts the mode of injecting glue to realize.As shown in Figure 3, at side opening first through hole 6 of ram swab case 3, get through seal groove 34 by at first; Open again the second through hole 7 in the bottom of ram swab case 3.The first through hole 6 and 7 is communicated with, and the side of the ram swab case 3 that the first through hole 6 is got through stops up, and prevents that external dust and iron filings from entering inside.If the first through hole 6 has been got through oil-containing groove 33, the oil-containing groove 33 and the opening between the seal groove that also need to get through stop up, when preventing injecting glue, glue leaks, between the bottom of ram swab case 3 and seal groove 34, to form the hole for injecting glue of a both ends open, carry out subsequently injecting glue, form sealing ring 35, thereby reduce the difficulty of installing.
As shown in fig. 1, in an embodiment of the present invention, also comprise oil storage box 8.Oil storage box 8 communicates with the oil-containing groove 33 of ram swab case 3.The horizontal plane at oil storage box 8 places is lower than oil-containing groove 33 residing horizontal planes, is used for the lubricating oil in the ram swab case 3 is imported in the oil storage box 8.
As shown in Figure 5, in a kind of lathe of embodiments of the invention, also comprise crossbeam slide 9 and crossbeam 10.Crossbeam slide 9 is connected with rotary slide base 1, and crossbeam slide 9 links together with crossbeam 10, and can be mobile at crossbeam 10.
The ram leak-proof arrangement of embodiments of the invention has simple in structure, lower-cost advantage; And have the duplicate protection of scraping bits plate and sealing ring, discarded lubricating oil also is convenient to reclaim and focus on.Thereby prolong the service life of lathe, improve the working (machining) efficiency of lathe.
More than specific embodiments of the invention are described in detail, but it is just as example, the present invention is not restricted to specific embodiment described above.When replacing with guide post or guide pipe etc. such as guide rail, equally also can play the guider that makes support bar enter smoothly the operating position.To those skilled in the art, any equivalent modifications that the present invention is carried out and substituting also all among category of the present invention.Therefore, not breaking away from impartial conversion and the modification of doing under the spirit and scope of the present invention, all should contain within the scope of the invention.
