Abstract

The utility model discloses a lubricating and cooling mechanism for a slide guiding rail, which is mainly suitable for main shaft systems of optical processing machine tools and metal cutting machine tools requiring high speed revolution and high precision. The utility model adopts a main technical scheme that a lubricating and cooling mechanism comprising an oil cooling machine, a hydraulic station, a pipe, a connector, a temperature sensor, an orifice throttle and a miniature oil pump is matched with and mounted on the main shaft system of the machine tool. Practical application proves that the utility model can radically overcome the defects of unsmooth circular flow and ineffective heat exchange and lubrication of the lubricant in the original lubricating and cooling mechanism, realize smooth circular flow, accurately control the heat exchange degree, and improve the cooling and lubricating quality for the heating element, thereby satisfying technical requirements of machine tools.

Description

A kind of lubricated cooling body of rail plate

One, technical field

The utility model belongs to the lubricated cooling body of rail plate of a kind of plane rotation, mainly is applicable to rotation requires at a high speed, precision the is higher optics machining tool and the axis system of Metal Cutting Machine Tool.

Two, technical background

In machine industry, existing similar means has multiple, here be example with the lubricated cooling body of the polishing machine rail plate of processing optical part, see Fig. 1, machine-tool spindle system is made up of abrasive disk 1, oil baffle 5, transition disc 3, workpiece plate 4, fixed underpan 6, sliding friction face 7 etc., and lubricated cooling body is made up of a Cool oil machine 17, pipe 13, joint 16, lubricating oil 2 etc.Operation principle is: when abrasive disk 1 rotated at a high speed, transition disc 3 rubbed with the faying face (being the sliding friction face) 7 of fixed underpan 6, and generation high temperature, high temperature all can bring the performance of lathe, life-span etc. and seriously influence.Therefore refrigeration machine 17 is with lubricating oil 2, by manage 13, joint 16, cannelure 8 be injected into attrition surface 7, to reduce the attrition surface temperature, the lubricating oil that overflows to both sides from the guide rail attrition surface, in refrigeration machine, carry out heat exchange by gravity reflux, the cold oil that obtains by Cool oil machine injects attrition surface again, and so circulation is so that lathe can normally move.

But all there is certain problem in this method from theory and practice.This is because the active force of abrasive disk and processing work all imposes on the guide rail attrition surface, guide pass applying power is very big up and down, in conjunction with very tight, lubricating oil is difficult to overflow from the slit, oil return is again by gravity reflux, and mobile poor, lubricating oil can not fully circulate unobstructedly, thereby this mechanism makes lubricating oil can not effectively carry out heat exchange and lubricated, and actual effect is relatively poor.

Three, utility model content

The main technical problems to be solved in the utility model and purpose are, according to the deficiency that existing lubricated cooling body exists, on this basis, develop a kind of thermometric precise control, the mechanism that lubricating oil can circulate unobstructedly makes the lubricated cooling effect of axis system of lathe meet specification requirement.

Main technical schemes of the present utility model is: cooperate on the axis system of lathe the lubricated cooling body of a cover is installed, mechanism is connected with the temperature sensor that is installed in fixed underpan by line by Cool oil machine, the outlet of Hydraulic Station is by pipe, joint, with the orifice restriction device UNICOM in three cannelures on the fixed underpan, the hole UNICOM of the import of Hydraulic Station and miniature oil pump, joint and guide rail attrition surface below.

The present invention proves by practical application: lubricating oil can circulate unobstructedly, take away the heat of heater and improved lubricating axis system, the degree of can control carrying out heat exchange is controlled at the temperature of heater in the predefined scope, satisfies the machine tool technology requirement.

Fig. 2 is a package assembly schematic diagram of the present utility model.

Fig. 3 is that putting too of mark I schemed among Fig. 2.The also difference of expression and Fig. 1 mark circle inner structure.

Fig. 4 is the enlarged drawing of aperture flow controller 9 among Fig. 2.

Five, the specific embodiment

With reference to Fig. 2, the machine spindle system that the utility model is made up of abrasive disk 1, transition disc 3, oil baffle 5, workpiece plate 4, fixed underpan 6, sliding friction face 7 etc. and lumped together by lubricated cooling body that Cool oil machine 17, Hydraulic Station 15, pipe 13, joint 16, temperature sensor 10, line 11, orifice restriction device 9, miniature oil pump 12 etc. are formed finishes.

With reference to Fig. 2, main technical schemes explanation of the present utility model: on the axis system of lathe, cooperate the lubricated cooling body of a cover is installed, mechanism is connected with the temperature sensor 10 that is installed in fixed underpan 6 by line 11 by Cool oil machine 17, the outlet of Hydraulic Station 15 is by pipe 13, joint 16, with orifice restriction device 9 UNICOMs in three cannelures 8 on the fixed underpan 6, the hole UNICOM of the import of Hydraulic Station 15 and miniature oil pump 12, joint 16 and guide rail attrition surface 7 belows.

With reference to Fig. 2, operation principle of the present utility model is: the lubricating oil 2 after Hydraulic Station 15 freezes Cool oil machine 17 is taken away, the rail plate attrition surface 7 that is injected into heating through three cannelures 8 and the orifice restriction device of joint 16, fixed underpan 6, under the promotion of hydraulic oil, abrasive disk 1, transition disc 3 upwards float, and form the oil reservoir of a high pressure, when load variations, orifice restriction device 9 will block the variation of oil pressure, keep the stable of high pressure oil reservoir.Under the suction of miniature oil pump 12, the lubricating oil that has temperature overflows from the interior neighboring of guide rail attrition surface, and oily stream is taken away the heat of heater, be back in the Hydraulic Station 15, thus the temperature of reduction heater.Constantly cold oil being drawn into deep fat through Hydraulic Station 15, miniature oil pump 12 extracts out, carry out heat exchange, directly record the guide rail temperature by temperature sensor 10 again, the temperature controller that feeds back to Cool oil machine is handled, so controlled the degree of heat exchange fully, the temperature of heater has been controlled in the predefined scope.

With reference to Fig. 2, be equipped with in the Hydraulic Station 15: high-pressure oil pump 14, overflow valve,, fuel tank etc.; Cool oil machine 17 is oily refrigeration plants of the refrigerator type that can purchase on the market; Temperature sensor 10, miniature oil pump 12 and joint 16 are normal component.

With reference to Fig. 3,4, the fixed underpan 6 of machine-tool spindle system at the position near guide rail attrition surface 7, have three cannelures 8, and every groove assembles an orifice restriction device 9 respectively.(fixed underpan 6 in the prior art has only a cannelure 8 and no orifice restriction device 9).

With reference to Fig. 2, Cool oil machine 17 also can adopt the oily refrigeration plant of fan type.
