Abstract
The utility model relates to a numerical control machine spindle axis cooling device which belongs to the field of numerical control machines, and is provided with a spindle axis inner cover. A spiral groove is processed at the outer surface of the spindle axis inner cover; a spindle axis outer cover is sheathed on the spindle axis inner cover; the spindle axis outer cover and the spindle axis inner cover are in interference fit; a water distribution gland and a seal ring are respectively assembled at the tail ends of the spindle axis outer cover and the spindle axis inner cover; and a cooling liquid inlet and a cooling liquid outlet are processed on the water distribution gland, and are respectively communicated with the spiral groove on the outer surface of the spindle axis inner cover. For the cooling device, by adopting a spindle axis device, the inner ring of a bearing of the spindle can be conveniently cooled so as to ensure that the inner ring and the outer ring of the bearing are cooled simultaneously. In addition, as the spindle axis of a numerical control machine has a double-layer wall structure, the bending resistance and the torsion resistance of the spindle axis are promoted to a certain extent.
Description
Technical field
The utility model relates to the Digit Control Machine Tool field, specifically a kind of main shaft of numerical control machine tool axle center cooling device.
Background technology
As everyone knows: at present, the main shaft cooling of Digit Control Machine Tool generally all is that water jacket carries out the fluid cooling outside main shaft, this mode is simple and convenient, but have one very important problem be difficult to solve, this exactly mode can only be cooled off the outer ring of main shaft bearing, and powerless to the heating of inner ring.And owing to expand with heat and contract with cold, the main shaft bearing outer ring is owing to cooling is shunk, and inner ring expands because of heating, and ball is inside and outside stressed, and friction strengthens, and has quickened the heating of main shaft bearing on the contrary.
Summary of the invention
The purpose of this utility model just is the shortcoming that can not cool off the main shaft inner ring for the spindle cooling structure that overcomes existing Digit Control Machine Tool, a kind of main shaft of numerical control machine tool axle center cooling device is provided, this device not only can cool off the outer ring of main shaft bearing, and can the inner ring of main shaft bearing be cooled off, thereby truly suppress the heating of main shaft bearing, the dynamic accuracy when having guaranteed spindle operation.
The utility model adopts following technical solution: a kind of main shaft of numerical control machine tool axle center cooling device, be provided with spindle axis internal layer cover, spindle axis internal layer cover outer surface is processed with helicla flute, the spindle axis internal layer puts and is set with the outer cover of spindle axis, the outer cover of spindle axis adopts interference fit with spindle axis internal layer cover, the outer cover of spindle axis is equipped with branch hydraulic pressure lid and sealing ring with the tail end of spindle axis internal layer cover, divide hydraulic pressure to cover and be processed with cooling fluid inlet and cooling liquid outlet, cooling fluid inlet and cooling liquid outlet are connected with the helicla flute that the spindle axis internal layer overlaps on the outer surface respectively.
The beneficial effects of the utility model are that the spindle axis device that passes through to be adopted can cool off the main shaft bearing inner ring easily, obtains cooling simultaneously to guarantee bearing enclose.Because spindle axis is the two layers of walls structure, the bending resistance of spindle axis, torsion proof ability also obtain certain lifting in addition.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model.
The outer cover of 1. spindle axis among the figure, 2. spindle axis internal layer cover, 3. cooling fluid inlet, 4. minute hydraulic pressure lid, 5. sealing ring, 6. cooling liquid outlet.
The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments, to help understanding content of the present utility model.
As shown in Figure 1, the utility model is provided with spindle axis internal layer cover 2, the outer surface of spindle axis internal layer cover 2 is processed with helicla flute, can carry out the storage and the circulation of cutting fluid, be set with the outer cover 1 of spindle axis on the spindle axis internal layer cover 2, the outer cover 1 of spindle axis adopts interference fit with spindle axis internal layer cover 2, two parts are after turning is finished, the outer cover of spindle axis 1 heating back is assembled into an one-piece parts with spindle axis internal layer cover 2, carries out whole heat treatment and accurate grinding and assembling then.Tail end at the outer cover 1 of spindle axis and spindle axis internal layer cover 2 is equipped with branch hydraulic pressure lid 4 and sealing ring 5 then, can be easily the inner ring of main shaft bearing be cooled off by the cooling fluid inlet 3 on minute hydraulic pressure lid 4 and cooling liquid outlet 4.Utilize the common type of cooling by the outer cover 1 of spindle axis in addition, can cool off the main shaft bearing outer ring, cool off simultaneously to reach the main shaft bearing Internal and external cycle, the temperature constant state of assurance main shaft bearing truly makes the good dynamic accuracy of the on-stream maintenance of main shaft.
