According to the feeding screw rod lubrication mechanism, a forced-oiling lubrication mode is adopted for replacing a mode in the prior art, and the structure of a feed screw nut is improved, so that a whole screw pair joint area is provided with oil for lubrication, the lubrication efficiency is greatly improved, further the moving rate of the planomiller is greatly improved, and the equipment maintenance cost is reduced.

Description

A kind of feed screw mandrel lubricating structure of planer-type milling machine

Technical field

The utility model relates to gantry association wound apparatus field, is specifically related to a kind of feed screw mandrel lubricating structure of planer-type milling machine.

Background technology

The vertical major case feed screw mandrel of planer-type milling machine generally adopts oil dripping single-point lubricating system, and the screw pair that often has feed campaign is lubricated very insufficient, and in production, the heavy wear of screw pair nut is even scrapped frequently.

This kind of lubricating system adopts siphonage to think the oiling of screw pair lubricant housings, the supply of fluid is discontinuous point type oiling, and its lubricated scope is very narrow, and the working region of screw pair is large, therefore the screw pair of the overwhelming majority moves at semi-dry friction state, therefore need frequent feed screw nut, equipment mobility declines, and maintenance cost raises.

Utility model content

For solving the problems of the technologies described above, we have proposed a kind of feed screw mandrel lubricating structure of planer-type milling machine, use pressure oil injecting lubricating instead, and have improved feed screw nut's structure, make whole screw pair bonding land have oil lubrication, and lubricated usefulness is greatly improved.

For achieving the above object, the technical solution of the utility model is as follows:

A feed screw mandrel lubricating structure for planer-type milling machine, comprises transmission nut body, nut inner core, screw mandrel and lock-screw;

Described nut inner core in a tubular form, there is transmission internal thread its inside, and its outside axis offers oil groove, and described oil groove rear and front end is not open-minded, on described oil groove, be laid with 3 radial direction oil, described radial direction oil runs through described oil groove bottom and described transmission internal thread top;

Described nut inner core outside is also provided with positioning screw hole, and described screw is blind hole;

Described nut inner core is located at described transmission nut body inner side, and described transmission nut body is fixed described nut inner core by lock-screw;

The internal thread of the external screw thread of described screw mandrel and described nut inner core is suitable;

Described transmission nut body also offers pressure pouring orifice, and described pressure pouring orifice communicates with described oil groove.

Preferably, described oil groove is 3, is distributed in described nut inner core outside.

By technique scheme, the utility model is by using pressure oil injecting lubricating instead, and improved feed screw nut's structure, make whole screw pair bonding land there is oil lubrication, lubricated usefulness is greatly improved, and then has improved the mobility of planer-type milling machine, reduces cost of equipment maintenance.

Brief description of the drawings

In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skill in the art, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.

Fig. 1 is the structural representation of the feed screw mandrel lubricating structure of the disclosed a kind of planer-type milling machine of the utility model embodiment;

Fig. 2 is the generalized section of Fig. 1.

Numeral and the represented corresponding component title of letter in figure:

Detailed description of the invention

Below in conjunction with embodiment and detailed description of the invention, the utility model is described in further detail.

Embodiment

As shown in Figure 1, a kind of feed screw mandrel lubricating structure of planer-type milling machine, comprises transmission nut body 1, nut inner core 2, screw mandrel 3 and lock-screw 4;

Described nut inner core in a tubular form, there is transmission internal thread its inside, and its outside axis offers oil groove, and described oil groove rear and front end is not open-minded, on described oil groove, be laid with 3 radial direction oil, described radial direction oil runs through described oil groove bottom and described transmission internal thread top;

Described nut inner core outside is also provided with positioning screw hole, and described screw is blind hole;

Described nut inner core is located at described transmission nut body inner side, and described transmission nut body is fixed described nut inner core by lock-screw;

The internal thread of the external screw thread of described screw mandrel and described nut inner core is suitable;

Described transmission nut body also offers forces pouring orifice 5, and described pressure pouring orifice communicates with described oil groove;

Described oil groove is 3, is distributed in described nut inner core outside.

The utility model adopts the mode of forcing oiling, fluid is flowed through radial direction oil to the land of screw pair through oil groove, owing to having opened three radial direction oil an oil groove bottom, ensured before screw mandrel in after each section all have fluid to inject, and oil groove front and back end all seals, and has ensured oil storage function.

By technique scheme, the utility model is by using pressure oil injecting lubricating instead, and improved feed screw nut's structure, make whole screw pair bonding land there is oil lubrication, lubricated usefulness is greatly improved, and then has improved the mobility of planer-type milling machine, reduces cost of equipment maintenance.

Above-described is only the feed screw mandrel lubricating structure preferred embodiment of a kind of planer-type milling machine of the present utility model; should be understood that; for the person of ordinary skill of the art; do not departing under the prerequisite of the utility model creation design; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
