NC rotary table divides oil jacket when work, owing to part is made reason or sealing part abrasion reason, through use after a while, seepage to a certain degree always occurs.If the fluid of seepage is sneaked in the worm and gear lubricating oil, the composition of lubricating oil is changed, quicken the wearing and tearing of worm and gear, cause the forfeiture of machine tool accuracy.
Granted publication number is 201346720Y, and Granted publication day is that the Chinese patent literature on November 18th, 2009 discloses a kind of numerical control horizontal machining center.The technical scheme of being taked comprises main frame, automatic control tool changing system, cooling, lubricated accessory system, it is characterized in that: also comprise the automatic isolating construction of profit, promptly the outer edge at the bed piece guide pass is provided with oil-recovery tank, the terminal centre position of lathe bed is provided with oil storage pool, oil storage pool is provided with fuel outlet valve, and oil-recovery tank is connected with oil storage pool; And the both sides outside two guide rails of lathe bed are provided with the tank of collecting cooling fluid.Lubricating oil flows to the middle terminal oil storage pool of lathe bed along oil-recovery tank, and cooling fluid flows to water tank along tank.Thereby reach the purpose that profit separates automatically.Have simple in structurely, the cost maintenance cost is low, advantages such as energy-conserving and environment-protective.
But technique scheme still solve to be divided the fluid leakage problems of oil jacket when work, and fluid can be sneaked into to worm screw lubricating oil no matter, and the composition of lubricating oil is changed, and quickens the wearing and tearing of worm and gear, causes the forfeiture of machine tool accuracy.
The utility model content
For solving the problems of the technologies described above, the utility model proposes a kind of oil return mechanism that is used for the horizontal Machining centers NC rotary table, adopt the utility model, can effectively stop the fluid leakage problems of branch oil jacket when work, prevent that fluid from sneaking into to the worm and gear lubricating oil, improve the life-span of worm-and-wheel gear to greatest extent, efficiently solved the danger that the fluid seepage is brought.
The utility model is realized by adopting following technical proposals:
A kind of oil return mechanism that is used for the horizontal Machining centers NC rotary table, it is characterized in that: the mandrel that is fixed on the slide is provided with the oil return annular groove, divide between oil jacket and the mandrel and be provided with the multi-stage sealed annular groove that is positioned on the mandrel, the oil return annular groove is positioned at the below of described closure gasket groove, the end of oil return annular groove is provided with oil return opening, and described oil return opening connects collection container.
The rotating part of rotary table comprises revolving body and divides oil jacket, divides oil jacket to be fixed on the revolving body.
The index table of horizontal Machining centers passes through driven by servomotor with worm gear, worm screw.
Described slide is connected by combination bearing with rotating part.
Divide between oil jacket and the mandrel and be provided with a plurality of sealing rings.
Advantage of the present utility model shows:
1, because the utility model adopts " mandrel that is fixed on the slide is provided with the oil return annular groove; divide between oil jacket and the mandrel to be provided with the multi-stage sealed annular groove that is positioned on the mandrel; the oil return annular groove is positioned at the below of described closure gasket groove; the end of oil return annular groove is provided with oil return opening; described oil return opening connects collection container " such technical scheme, is that the prior art of representative is compared with Granted publication number for 201346720Y, the utility model can effectively be stopped the fluid leakage problems of branch oil jacket when work, prevent that fluid from sneaking into to the worm and gear lubricating oil, improve the life-span of worm-and-wheel gear to greatest extent, efficiently solved the danger that the fluid seepage is brought.
2, adopt the utility model, compact conformation need not to increase new part and can realize oil return; Assembling is simple, and sealing is reliable, fluid does not take place after the use sneak into worm and gear lubricating oil phenomenon.
