Description
Technical field
The utility model relates to a kind of improved machine tool main shaft structure.
Background technology
In Digit Control Machine Tool processing, be unable to do without the utilization to main shaft, the machining accuracy of the accuracy affects lathe of main shaft itself, main shaft of numerical control machine tool in the market adopts mechanical rolling bearing.
Have that precision is not high, wearing and tearing are large, service life is short, especially temperature is higher in poor, the work of radiating effect, high temperature can reduce its service life for a long time, repair and replacement frequency is higher, high temperature also can bring certain impact to miscellaneous part simultaneously.
The coolant flow of utilizing of existing machine tool chief axis is taken away heat, reaches the object of heat radiation, but this device processing cost is high, and cooling device need to occupy certain space, concerning the lathe of some compact conformations, places cooling device very inconvenient.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of simple in structure, use, easy for installation, simple to operate, machining accuracy is high, heat radiation, high lubricating effect, convenient later maintenance, laborsaving, cost is low, applied widely, long service life, has the improved machine tool main shaft structure of safe and reliable effect.
For addressing the above problem, the utility model adopts following technical scheme:
A kind of improved machine tool main shaft structure, comprise main shaft, axle sleeve and scroll chuck, described main shaft is arranged in axle sleeve, described scroll chuck is arranged on main shaft one end, in described main shaft, be provided with a ventilation shaft, described main shaft is provided with a hot channel, described hot channel is connected with ventilation shaft, in described hot channel, be provided with bracing frame, support frame as described above is provided with rotating shaft, and described rotating shaft is provided with cooling wind blade, in described main shaft, be provided with lubricated road, described main shaft is provided with pouring orifice, and described pouring orifice is connected with lubricated road, and described pouring orifice is provided with seal cover.
As preferred technical scheme, described axle sleeve is provided with for supporting and supply the bearing of main shaft rotation, and described bearing is provided with four.
As preferred technical scheme, described ventilation shaft runs through scroll chuck.
As preferred technical scheme, described scroll chuck is provided with three fixed claw pin.
As preferred technical scheme, described main shaft and scroll chuck removably connect.
The beneficial effect of a kind of improved machine tool main shaft structure of the utility model is: during use, when main shaft drives while carrying out High Rotation Speed by being arranged on drive motors in lathe, in ventilation shaft, can enter a large amount of wind, and the wind outside main shaft and the wind in main shaft form a height wind, the cooling wind blade that makes to be arranged in hot channel starts rotation, and then play the effect of cooling, by set pouring orifice and lubricated road, be used in combination, can guarantee the lubricant effect of main shaft when long-term work, avoid lubricated and not in placely occur that main shaft friction is larger, thereby affect its precision.It is simple in structure, use, easy for installation, simple to operate, and machining accuracy is high, heat radiation, high lubricating effect, convenient later maintenance, laborsaving, cost is low, applied widely, and long service life has safe and reliable effect.
