Abstract
The utility model relates to a machine tool spindle cooling device, which is provided with a spindle mounted in a spindle box through a bearing; a cooling spindle, a cooling channel of the bearing, box body input and output joints communicated with the box body are arranged in the spindle box body, an oil piping system composed of an oil cooler, a filter, an oil tank, an oil pump and a dividing valve is arranged in the spindle box body; the input end and output end of the oil pump are respectively connected with the oil tank and the dividing valve, the output end of the dividing valve is correspondingly connected with the cooling spindle in the spindle box body and the input joint of the bearing cooling channel, the output joint of the spindle box body is convergent to be connected with the oil cooler and the output end of the oil cooler is connected with the oil tank through the filter. As the machine tool cooling device proposed in the utility model is adopted, the cooling fluid flows through the cooling spindle in the spindle box body and the cooling channel of the bearing to rapidly eliminate heat generated by the spindle and the bearing so that the spindle cannot have temperature change due to heat retention and the heat deformation of the spindle is reduced and the accuracy of the spindle component is stabilized.
Description
Technical field:
The utility model relates to a kind of lathe metal cutting process technology, more specifically to a kind of machine tool chief axis cooling device.
Background technology:
In metal cutting processing, particularly the high precision machine tool of many main shafts must prevent the temperature rise of machine tool chief axis and the thermal deformation that causes, because thermal deformation will directly cause precision low, easily produces substandard products.Be the variations in temperature that will prevent that heat retention face from producing, the heat dissipation with the main shaft bearing place just seems very necessary rapidly.For the common way of heat that will dissipate is the method that the employing refrigerants vaporize absorbs heat, but this method and technology difficulty is big, wayward, with high costs, can produce local overcooling, the uneven phenomenon of temperature distribution, and this is the problem that pay attention to.
The utility model content:
The purpose of this utility model is the heat machine tool chief axis cooling device that can distribute rapidly, that prevent main shaft generation thermal deformation that provides a kind of main shaft to rotate generation at a high speed at the prior art weak point.
The purpose of this utility model is to realize by following measure: a kind of machine tool chief axis cooling device, be provided with main shaft, main shaft is installed in the main spindle box by bearing, its special character is: also have by the cooling duct that is provided with cooling main shaft and bearing in the described main shaft casing to reach casing input, the out splice going splice that is communicated with it, oil cooler, filter, fuel tank, oil pump, the oil piping system that flow divider is formed; Described oil pump input, output be connected tank and flow divider respectively, the input adapter of cooling main shaft and bearing cooling duct in the main shaft casing of the output termination correspondence of flow divider connects oil cooler, oil cooler output through the filter connected tank after its main shaft casing out splice going splice converges.
Cooling duct in the described main shaft casing is two aspects, and one deck is positioned at the main shaft top, and another layer is positioned at the main shaft below, and the cooling duct enters after the aspect around flowing out in one week of aspect, and two cooling ducts have identical structure, are arranged side by side.
The fan-out of described flow divider is 2～4.
Compared with prior art, owing to adopted the machine tool chief axis cooling device that the utility model proposes, when flowing through the cooling duct of main shaft casing cooling main shaft and bearing, its cooling oil can eliminate the heat that produces on the main shaft rapidly, main shaft can not cause variations in temperature because of heat retention, reduce its thermal deformation, the precision of stabilize spindle assembly.Another advantage of the present utility model is the choke valve that can regulate on the flow divider, keeps the problem of each road main shaft temperature equilibrium of shunting.
Description of drawings:
Fig. 1 is the utility model example structure block diagram.
Fig. 2 is the cooling duct schematic diagram of present embodiment main shaft casing cooling main shaft and bearing.
The specific embodiment:
Below in conjunction with accompanying drawing the specific embodiment is elaborated:
Fig. 1 has provided the utility model example structure block diagram.A kind of machine tool chief axis cooling device is provided with: main shaft 1, main shaft is installed in the main spindle box 2 by bearing.Described main shaft casing is provided with the cooling duct of cooling main shaft and bearing and the casing input adapter 3,4 that is communicated with it, out splice going splice 5,6, oil cooler 7, filter 8, fuel tank 9, oil pump 10, the oil piping system that flow divider 11 is formed.Cooling duct in the described main shaft casing is two aspects, and one deck is positioned at the main shaft top, and another layer is positioned at the main shaft below, and the cooling duct enters after the aspect around flowing out in one week of aspect, and two cooling ducts have identical structure, are arranged side by side, and its profile is seen Fig. 2.Described oil pump 10 inputs, output be connected tank 9 and flow divider 11 respectively, and the branch way of flow divider is corresponding with the quantity of machine tool chief axis.The input adapter 3,4 of cooling main shaft and bearing cooling duct in the main shaft casing of the output termination correspondence of flow divider 11, fluid enter main shaft casing cooling chamber cooling main shaft bearing, the heat of dissipation main shaft bearing.Fluid connects oil cooler 7 after main shaft casing out splice going splice 5,6 converges, by the oil of oil cooler cooling intensification.Oil cooler 7 outputs are through filter 8 connected tanks 9.The fan-out of described flow divider is 2～4, also can connect 2～4 main shaft casings simultaneously.
During the utility model work, start the oil pump running and suck oil enters correspondence through flow divider the casing input adapter that is communicated with main shaft cooling cavity from fuel tank, fluid enters the main shaft bearing that main shaft casing cooling chamber body chilling temperature raises, its heat dissipates, thereafter entering oil cooler reduces its temperature and returns fuel tank through filter again, so circulation.Each road throttling passage of flow divider can be by its flow size by this road of the throttle valve adjustment on the valve.
The foregoing description does not constitute restriction of the present utility model, and all employings are equal to the technical scheme that form obtained of replacement or equivalent transformation, all drop within the protection domain of the present utility model.
