The utility model is characterized in that the oil holder is bell socketed on the upper end or the external end of the kinematic pair formed by a screw rod 1 and a nut 2, the self lubricating nut 5 made of macromolecule materials is arranged between the screw rod 1 and the oil holder 4, the self lubricating nut 5 and the oil holder 4 are connected into one, and the space capable of placing lubricant is formed between the oil holder 4, the nut 2 and the screw rod 1. The device is simple, practical and rational in structure, and solves the problem of unequally adding lubricant by hand to the screw rod and the nut kinematic pair in the course of using a plurality of machine tools, and the waste of lubricant, and lubricant pollution by flushing around.
Description
Technical field
The utility model relates to lubricating arrangement, is specifically related to the lubricating arrangement of leading screw on a kind of lathe, nut kinematic pair.
Background technology
At present, screw mandrel 1, nut 2 mechanisms are all arranged on the multiple lathe that China various machining factory is using, generally nut 2 is connected into one with the walking mechanism 3 of compositions such as knife rest, horizontal stroke (indulging) upper tool post guiding mechanism or adjustment platform, screw mandrel 1, nut 2 constitute kinematic pair, and concrete structure as shown in Figure 1.Rotate situation lower nut and walking mechanism realization horizontal or the length feed or the vertical lifting of (rotation of a few cases lower nut) at screw mandrel, thereby realize the mobile and adjustment of walking mechanisms 3 such as knife rest.At this moment, should lubricate screw mandrel, lubricated again nut, because relative motion, lubricating of screw mandrel, nut kinematic pair is just very difficult.Most of lathes that present China is using, 5 * 22 meters plano milling and boring machines of Coburg, Germany that comprise import, generally the lubricating system of Cai Yonging is the method for artificial manual filling lubricating oil, do not adopt special equipment or instrument, concrete condition is manually to carry lubricating oil to cooperate the junction to drip lubricating oil from upper end screw mandrel 1, nut 2.
The drawback of the mode of this old-fashioned filling lubricating oil: the one, restive and grasp oil mass what, the lubricating oil that causes trickling everywhere on screw mandrel, nut and even the lathe, both contaminated environment had been wasted lubricating oil again; The 2nd, screw mandrel, nut are in running order, artificial being difficult to oil filling to kinematic pair cooperating face, so, oil filling gets very inhomogeneous on screw mandrel, nut operative minor working face total length, cause kinematic pair work oil starvation inevitably, make operative minor heel and toe wear occur, nut especially, the many materials of Da Jin are copper, softer relatively, it is faster to wear and tear, and has both increased the cost of changing consumable accessory, has influenced machine tool accuracy and factory work progress again; Because the uneven cohesion easily of hand oiling is in heaps, attach the abrasive wear that strengthens behind the dust in the air screw mandrel simultaneously.
The utility model content
Technical problem to be solved in the utility model is the lubricating arrangement how a kind of lathe upper screw rod, nut kinematic pair are provided, this device is simple and easy, practical, rational in infrastructure, solves inhomogeneous lubricating oil and the lubricating oil phenomenon of slime flux contaminated environment everywhere of wasting simultaneously of the lubricated oil pole of the manual filling of screw mandrel in present numerous lathe use, nut kinematic pair.
The technical problem that the utility model proposed is to solve like this: the lubricating arrangement of constructing a kind of lathe upper screw rod, nut kinematic pair, comprise oil containing drum 4, self-lubricating nut 5, oil filler 6 and exhaust outlet 7, it is characterized in that, described oil containing drum is set in the upper end or the outer end of the kinematic pair of screw mandrel 1 and nut 2 formation, be provided with the self-lubricating nut 5 that macromolecular material is made between screw mandrel 1 and the oil containing drum 4, self-lubricating nut 5 fixes as one with oil containing drum 4, and formation can hold the space of lubricating oil between oil containing drum 4 and nut 2, screw mandrel 1.
Lubricating arrangement according to lathe upper screw rod provided by the utility model, nut kinematic pair is characterized in that, described oil containing drum 4 is provided with oil filler 6 and exhaust outlet 7.
Lubricating arrangement according to lathe upper screw rod provided by the utility model, nut kinematic pair is characterized in that, described oil containing drum 4 is the interference fit clamping with nut 2 or is threaded; Lubricating arrangement and the nut 2 be made up of oil containing drum 4, self-lubricating nut 5, oil filler 6, exhaust outlet 7 form a synchronous integral body, and screw mandrel 1, nut 2 kinematic pairs are realized following the tracks of synchronously self-lubricate.
The beneficial effects of the utility model are as follows:
(1) lubricated good: employing of the present utility model, from motion tracking self-lubricate kinematic pair, make to be in the immersion that fit screw rod 1, nut 2 operative minor are in lubricating oil at work all the time, the operative minor lubricating status is extremely good.Changed the screw mandrel 1 that generally adopts before this, nut 2 operative minor and refueled uneven situation by manual, thus make operative minor particularly the copper nut wearing and tearing reduce, prolong service life greatly;
(2) economize on oil: because employing of the present utility model, lubricating oil is in the device of sealing without leakage all the time, and has lubricated the kinematic pair that has also only lubricated nut 2 motion places of arrival all the time, reduces the consumption of lubricating oil;
(3) working environment health, clean and tidy: employing of the present utility model, lubricating oil are in the device of sealing without leakage all the time, have changed the situation of artificial hand oiling before this and the lubricating oil that causes looses, lets out everywhere, pollute the situation of lathe working environment.
Description of drawings
Fig. 1 is the structural representation that lathe upper screw rod in the prior art, nut form kinematic pair;
Fig. 2 is the structural representation of lubricating arrangement provided by the utility model.
Wherein, 1, screw mandrel, 2, nut, 3, walking mechanism, 4, oil containing drum, 5, the self-lubricating nut, 6, oil filler, 7, exhaust outlet.
The specific embodiment
Below in conjunction with accompanying drawing lubricating arrangement provided by the utility model is elaborated.
As shown in Figure 2, this device is made up of oil containing drum 4, self-lubricating nut 5, oil filler 6, exhaust outlet 7, is to install oil containing drum 4 additional in former nut 2 upper ends or outer end, and oil containing drum 4 connects with nut 2; The self-lubricating nut of between oil containing drum 4 and screw mandrel, making 5 of the macromolecular material that self-lubricating function is arranged, nut 5 forms whole with oil containing drum 4; Installing oil filler 6 and exhaust outlet 7 on oil containing drum 4 shells.
The novel a kind of lathe upper screw rod that provides is provided this reality, the lubricating arrangement of nut kinematic pair, mainly be applicable to as plano milling and boring machine, floor type boring and milling machine, use screw mandrel on the various lathes such as drilling machine, nut body and the place that relative motion is arranged and need kinematic pair is lubricated, especially to old-fashioned, imported large-scale equipment such as plano milling and boring machine, screw mandrels such as floor type boring and milling machine, the nut kinematic pair is lubricated, behind installing the utility model, both played good lubrication, having reduced lubricating oil again spatters everywhere, stream, thereby leak contaminated environment, save lubricating oil simultaneously, prolonged the service life of kinematic pair greatly.
