Abstract
The invention discloses an air cooling device for controlling thermal deformation of a spindle box of a vertical machine tool, which comprises a spindle motor, the spindle box and an upright post, wherein a cover is arranged outside the spindle box; the cover and the spindle box form a closed space and the cover covers the spindle motor; the upper end of the cover is provided with a cooling fan and a ventilating hole; a cushion block is arranged between the spindle motor and the spindle box to ensure that a ventilating hole is formed between the spindle motor and the spindle box; the spindle box and the upright post are provided with ventilating holes; and the ventilating holes form a loop. The air cooling device performs forcible air cooling on a motor of a driving spindle and spindle box components of the machine tool through the fan to reduce the temperature of a spindle box system, and is provided with more heat insulating blocks to reduce the heat transferred from the motor to the spindle box to finally ensure that the temperature of the spindle box is distributed uniformly and the aim of improving the thermal stability of the machine tool is fulfilled.
Description
Technical field
The present invention relates to a kind of air-cooling apparatus that is used to control vertical processing machine tool (comprising vertical machining centre, vertical lathe, drilling machine and milling machine etc.) thermal deformation of spindle box, belong to the machine tool thermal design field.
Background technology
For improving the production efficiency of lathe, main shaft develops towards the high-power direction of high speed, and main shaft bearing and drive motors produce big heat, produces thermal deformation thereby cause machine tool component to produce uneven temperature field, and fuel factor has a strong impact on mach precision.The heat that bearing produces can be taken away through the compressed air of oil-air lubrication, and this mode can effectively reduce the heat that is delivered to lathe headstock; And the heat that motor produces dispels a part except carrying cooling fan, and remaining major part is then transferred to main spindle box through the motor end face, makes main spindle box produce uneven temperature field, and structure generation thermal deformation causes the drift of main shaft end face.
In order to eliminate the influence of fuel factor to machine finish; At present valid approach is through setting up the hot error model of concrete lathe; Predict hot error and in digital control system, realize real-Time Compensation, but need many temperature sensors and corresponding data acquisition system, and the hot error model of being set up does not have versatility; Implementation cost is very high, is not used widely.
Summary of the invention
Goal of the invention: the objective of the invention is to overcome deficiency of the prior art, a kind of air cooling device that is used to control thermal deformation of spindle box of vertical machine tool of good cooling effect is provided.
Technical scheme: the air cooling device that is used to control thermal deformation of spindle box of vertical machine tool of the present invention; Comprise spindle motor, main spindle box and column; Said main spindle box is outside equipped with cover body, and said cover body and said main spindle box form enclosure space and with said spindle motor clad; The upper end of said cover body is provided with cooling fan and air vent; Be provided with cushion block between said spindle motor and the said main spindle box, make to form air vent between said spindle motor and the said main spindle box, cushion block can be selected heat insulation or radiating block, and the material of cushion block and size are selected according to the temperature of spindle motor; Suitable position has air vent on said main spindle box and the said column, and above-mentioned all air vents form a loop.The air vent of air vent between air vent on main spindle box and the column and spindle motor and the main spindle box and cover body upper end forms a ventilating duct; Extraneous air gets into ventilating duct from the air vent on main spindle box and the column; Discharge from the air vent of cover body upper end; Make the path flows of air, force cooling drive motors, main spindle box and column guide rail by design.
Said cooling fan is a tube-axial fan, and its rotating speed can be regulated according to the work temperature rise of lathe key position automatically.
Also be provided with sensor at the top of said main spindle box and the guide rail place of said column; Said sensor is connected with said cooling fan; As detect the operating temperature at main shaft casing top and column guide rail place in real time, when temperature surpasses a certain setting value, fan will start; And, regulate fan speed according to temperature rise trend.
Beneficial effect: the present invention compared with prior art, its beneficial effect is: (1) the present invention is with respect to heat error compensation, adopts cooling air forced-convection heat transfer, the scheme that possesses skills is simple, adaptability is good, safeguards advantages such as simple; (2) apparatus of the present invention are carried out the forced air cooling through fan to the motor of driving main shaft and machine tool chief axis box part; Reduce the temperature of main-shaft box system; Reduce the heat that motor transmits to the main shaft casing through increasing heat insulation; Finally make the main spindle box uniformity of temperature profile, reach the purpose that improves machine tool thermal stability; (3) apparatus of the present invention can be used for vertical machines such as vertical machining centre, vertical lathe, drilling machine and milling machine; With certain machining center main spindle box is example; After this cover forced air cooling device was installed, the whole temperature rise of main-shaft box system reduced, and main shaft casing mating surface temperature descends; End face obviously reduces to the temperature difference between the bottom surface, and the displacement of main shaft end face has reduced by 20%.
