The specific embodiment
As shown in Figures 2 to 7, a kind of main shaft labyrinth structure that the utility model embodiment provides, it is mainly comprised of an axle bed 20, an axle 30, a drive end bearing bracket 40, a collar member 50 and an air flue 60, wherein:
This axle bed 20, has the radial line direction 22 of an axis direction 21 and vertical this axis direction 21.
This axle 30, is hubbed in this axle bed 20 along this axis direction 21, in order to holding cutter (not showing on figure).
This drive end bearing bracket 40, is fixedly arranged on this axle bed 20 along this axis direction 21, and has the ring bottom surface 42 that Yi Neihuan side 41 and Yi Yuneihuan side 41 join.
This collar member 50, the mode of establishing with spiral shell along this axis direction 21 is fixedly arranged on this axle 30, and has a pair of outer shroud side 51 and a pair of top surface of ring 52 that should encircle bottom surface 42 and join with outer shroud side 51 that should Nei Huan side 41.
This air flue 60, be located between this axle bed 20, drive end bearing bracket 40 and this collar member 50, and comprise a gas access 61 and and be located at annular gas between this collar member 50 and this drive end bearing bracket 40 outlet 62, and this annular gas outlet 62 along these radial line direction 22 output gases to form an air curtain 70, in the present embodiment, this axle bed 20 is located in this air flue 60 gas access 61, and this air flue 60 comprises the first gas section 63 radially of being located at this axle bed 20 and having this gas access 61, one be located at this axle bed 20 and with this first the first axial gas section 64 that radially gas section 63 is communicated with, one the second axial gas section 65 of being located at this drive end bearing bracket 40 and being communicated with this first axial gas section 64, one the second gas section 66 radially of being located at this drive end bearing bracket 40 and being communicated with this second axial gas section 65, one be located between this drive end bearing bracket 40 and collar member 50 and with this second the 3rd axial gas section 67 that radially gas section 66 is communicated with, and a 3rd gas section 68 radially of being located between this drive end bearing bracket 40 and collar member 50 and being communicated with the 3rd axial gas section 67, and the 3rd radially gas section 68 there is this annular gas outlet 62, in addition, the 3rd axial gas section 67 is formed by this drive end bearing bracket 40Nei Huan side 41 and the outer shroud side 51 of this collar member 50, the 3rd radially gas section 68 by this drive end bearing bracket 40Huan bottom surface 42 and the top surface of ring 52 of this collar member 50, formed.
The above is structure and the configuration explanation thereof of each main member of the utility model embodiment.Effect as for the utility model embodiment, makes the following instructions.
As Fig. 4, shown in Fig. 6, when after the 61 input gases (as shown by arrows) of this air flue 60 gas access, this gas this first gas section 63 radially of can flowing through, the first axial gas section 64, the second axial gas section 65, the second gas section 66 radially, the 3rd axial gas section 67, and the 3rd gas section 68 radially, finally by these annular gas outlet 62 outputs, form an air curtain 70 again, and because this annular gas outlet 62 is shaped along this radial line direction 22, therefore, the gas of exporting just along this radial line direction 22, form an annular air curtain 70 radially, accordingly, this annular air curtain 70 is entered main shaft inside by this collar member 50 and the joining place of this drive end bearing bracket 40 except preventing chip dust and cooling fluid, more being avoided adding the chip dust and the cooling fluid that produce man-hour is up sent forth by the place of processing.
In addition, formed annular air curtain 70 range size of the utility model main shaft labyrinth structure can be controlled by inputted gas pressure size, the gas pressure of inputting is larger, formed annular air curtain 70 radial line direction 22 covering scopes are relatively large, the gas pressure of inputting is less, formed annular air curtain 70 radial line direction 22 covering scopes are relatively little, therefore, the size that is not limited to main shaft can produce larger air curtain 70 scopes, to increase waterproof and dustproof scope, avoid adding the chip dust and the cooling fluid that produce man-hour is up sent forth by the place of processing simultaneously, promote the applicability of this main shaft labyrinth structure.
It is worth mentioning that, in the present embodiment, the main mode that this collar member 50 is established with spiral shell is fixedly arranged on this axle 30, and this collar member 50 and this drive end bearing bracket 40 form a part for these air flues 60, therefore, this collar member 50 is not compressed by this drive end bearing bracket 40, and is not needing to remove under the state of this axle 30 and can this collar member 50 separated, to reach this main shaft labyrinth structure object comparatively easily in repair and replacement or maintenance cleaning.
Finally, as shown in Fig. 4, Fig. 6, in this air flue 60, connect this second gas section 66 and the 3rd axial gas section 67 of the 3rd between gas section 68 radially radially, the 3rd axial gas section 67 with this second radially gas Duan66 junction form the high pressure inner chamber A that a spatial mode is greater than the 3rd axial Qi Duan67Qi elsewhere, make to input the pressure producing after gas and be greater than the radially pressure of gas section 68 and annular gas outlet 62 of the 3rd axial gas section 67, the 3rd in this high pressure inner chamber A, therefore more can guarantee that this processing machine reaches waterproof and dust reduction capability in process.
Below through the specific embodiment and the embodiment the utility model is had been described in detail, but these not form restriction of the present utility model.In the situation that not departing from the utility model principle, those skilled in the art also can make many distortion and improvement, and these also should be considered as protection domain of the present utility model.
