Abstract
Disclosed is a motor spindle lubrication temperature controlling system of a high speed machine tool comprising a motor spindle, an oil transferring equipment, a gas transferring equipment, an oil and gas mixing valve, a recycling system and a waste oil recovery equipment. The oil transferring equipment and the gas transferring equipment are respectively connected with the input end of the oil and gas mixing valve while the output end of the oil and gas mixing valve is connected with the bearing of the motor spindle, and the lower part of which is connected with the waste oil recovery equipment. The recycling system is connected with a cooling duct of the motor spindle. The temperature controlling system has the advantages that the motor spindle can be well lubricated and cooled down in time through adding oil and gas lubrication and cooling water circulation to the motor spindle so as to prevent the motor spindle from excessive friction and quick temperature increase and maintain the motor spindle in optimum condition, thus developing the working performance of the machine tool.
Description
Technical field
The utility model relates to a kind of accessory system of lathe, particularly a kind of lubricating system that is used for the high-speed machine tool motor.
Background technology
High-speed machine tool, owing to used high-speed electric expreess locomotive, so its serviceability at first depends on the performance of high-speed electric expreess locomotive main shaft.Existing high-speed electric expreess locomotive range of spindle speeds reaches 240rpm～24000rpm, have that moment of torsion is big, rotating speed is high, the advantage of speed-regulating range width, but produce also thus that also electric machine main shaft bearing preload is big, main shaft rubs easily when running up, distinct issues comparatively such as heating.If handle badly, electric machine main shaft may damage even burn, thereby reduces machining accuracy and service life, and therefore many high-speed machine tools also can lose its high speed performance, makes the lathe can't operate as normal.
Summary of the invention
Technical problem to be solved in the utility model is to overcome the above-mentioned defective of prior art and provide a kind of high-speed machine tool electric machine main shaft to lubricate temperature-controlling system, makes it can make electric machine main shaft keep suitable temperature, prevents its overtemperature and influences service behaviour.
The utility model solves the problems of the technologies described above the technical scheme that is adopted:
The high-speed machine tool electric machine main shaft lubricates temperature-controlling system, it is characterized in that: comprise electric machine main shaft, fuel delivery device, air delivery device, oil gas mixing valve, the circulatory system and drain oil recovery equipment, described fuel delivery device links to each other with the input of oil gas mixing valve respectively with air delivery device, the oil gas output of oil gas mixing valve links to each other with the electric machine main shaft bearing, electric machine main shaft bearing bottom links to each other with drain oil recovery equipment, and the described circulatory system links to each other with the cooling duct of electric machine main shaft.
When motor uses, open above-mentioned temperature-controlling system, lubricating oil is gentle to enter the mixed oil and gas that is mixed into setting pressure in the oil gas mixing valve by fuel delivery device and air delivery device respectively, from mixing valve, come out to enter in the electric machine main shaft bearing again, electric machine main shaft is carried out oil-air lubrication, and the temperature rising situation according to electric machine main shaft is opened water circulation system, and by water circulation system electric machine main shaft being lowered the temperature remains in the rational temperature electric machine main shaft.
Compared with prior art, advantage of the present utility model is:
By electric machine main shaft being increased oil-air lubrication and cooling water circulation, it is good lubricated that electric machine main shaft had both been obtained, and prevents the electric machine main shaft excessive friction, heats up too fastly, and electric machine main shaft is in time lowered the temperature, make electric machine main shaft keep optimum state, thereby improve the service behaviour of lathe.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
The specific embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
As shown in Figure 1, the high-speed machine tool electric machine main shaft lubricates temperature-controlling system, comprise electric machine main shaft 3, fuel delivery device 1, air delivery device 8, oil gas mixing valve 2, water circulation system 4 and drain oil recovery equipment, described fuel delivery device 1 links to each other with the input of oil gas mixing valve 2 respectively with air delivery device 8, the oil gas output of oil gas mixing valve 2 links to each other with electric machine main shaft 3 bearing lubrication chambeies, bottom, electric machine main shaft bearing lubrication chamber links to each other with drain oil recovery equipment, and the described circulatory system links to each other with the cooling duct of electric machine main shaft.
The pressure that Pressure gauge 7 can intuitively show fuel-air mixture is set in the above-mentioned fuel-air mixture passage, is convenient to observe and control.
Above-mentioned fuel delivery device 1 links to each other with controller with air delivery device 8, controls its export ratio.
Above-mentioned drain oil recovery equipment can be pump 5 and waste oil container 6, and the import of pump 5 is connected with the end opening in electric machine main shaft bearing lubrication chamber, and the outlet of pump 5 is connected with waste oil container 6, by pump 5 waste lubricating oil is collected in the waste oil container 6 from the motor lubricating cavity.
In order to guarantee main shaft bearing sufficient lubrication and heat radiation rapidly, adjust mixed oil-air pressure by fuel delivery device, air delivery device adjustment oil, gas ratio and by mixing valve, the pressure switch value of preferably setting mixing valve 2 is 0.4MP, the oil-air pressure of spindle end is about 0.15MP like this, and can monitor main shaft bearing oil-air lubrication situation according to this by digital control system.
Above-mentioned fuel delivery device 1 preferably links to each other with controller with air delivery device 8, controls its export ratio by controller.
The pressure oil gas major part that enters in the main shaft vapors away with the heat that electric machine main shaft 1 produces, but there is a spot of condensation to deposit, as can not in time discharging, also can main shaft be heated up the heat conduction, therefore also be provided with drain oil recovery equipment in the said system, utilize the vavuum pump in the drain oil recovery equipment that the deposition lubricating oil in the principal axis lubrication chamber is in time reclaimed.
The above-mentioned circulatory system imposes the circulation cooling to the main shaft outside.The circulatory system adopts the temperature control unit that has refrigeration and heat two kinds of functions, and establishes flowmeter, after output coolant temperature scope is set, by adjusting coolant rate, final strict control main shaft temperature scope.
Said system just can strictness have been controlled spindle heat generation by mutual coordination and complementation between oil-air lubrication and the circulation cooling.The machine motor main shaft is in continuously running 1 hour of 24000rpm, 25 ℃ of strong point heating position maximum temperaturerises, and the main shaft thermal equilibrium temperature is 43 ℃, thus effectively controlled the main shaft thermal stretching, improved the machining accuracy of lathe greatly.
