Summary of the invention
The purpose of this utility model is to provide a kind of main shaft of numerical control machine tool dust-proof sealing device of simple in structure, good dustproof effect.
The purpose of this utility model is achieved through the following technical solutions: a kind of main shaft of numerical control machine tool dust-proof sealing device, it comprises the dust preventing component A being located on main shaft and is located at bearing block and the dust preventing component B with the coaxial corresponding matching of dust preventing component A, described dust preventing component A comprises the dust ring A that more than two concentric interval is convexly equipped with, described dust preventing component B comprises the dust ring B that more than two concentric interval is convexly equipped with, described dust ring A and dust ring B all tilt laterally and acutangulate with place face, dust ring A and dust ring B are crisscross arranged, and dust ring A and dust ring B end are near corresponding surface.
Compared to prior art, the utility model has the advantage of: the gap location of the utility model between main shaft and the bearing block dust ring that multiple tracks tilts laterally that is crisscross arranged, in the time that rotating, main shaft can form dustproof wind barrier, can effectively stop the impurity such as ash content and cooling fluid to enter main shaft inside, simple in structure, dust-proof effect is splendid.
Brief description of the drawings
Fig. 1 is the structural representation of a kind of embodiment main shaft of numerical control machine tool of the utility model dust-proof sealing device.
Fig. 2 is A place enlarged drawing in Fig. 1.
Label declaration: 1 main shaft, 2 bearing blocks, 3 dust preventing component A, 4 dust preventing component B, 5 dust ring A, 6 dust ring B.
Detailed description of the invention
Below in conjunction with Figure of description and embodiment, the utility model content is elaborated:
The embodiment schematic diagram of a kind of main shaft of numerical control machine tool dust-proof sealing device providing for the utility model as shown in Figure 1 to Figure 2.
A kind of main shaft of numerical control machine tool dust-proof sealing device, it comprises the dust preventing component A3 being located on main shaft 1 and is located at bearing block 2 and the dust preventing component B4 with the coaxial corresponding matching of dust preventing component A3, described dust preventing component A3 comprises the dust ring A5 that more than two concentric interval is convexly equipped with, described dust preventing component B4 comprises the dust ring B6 that more than two concentric interval is convexly equipped with, described dust ring A5 and dust ring B6 all tilt laterally and acutangulate with place face, dust ring A5 and dust ring B6 are crisscross arranged, and dust ring A5 and dust ring B6 end are near corresponding surface.The end of dust ring A5 is near dust ring B6 place plane, and the end of dust ring B6 is near dust ring A5 place plane.
Angle between the lateral surface of described dust ring A5 and its place plane is 30-65 degree; Angle between the lateral surface of described dust ring B6 and its place plane is 30-65 degree.
When Digit Control Machine Tool or spindle of numerical control lathe 1 rotate, the dust preventing component A3 that drive is sheathed on main shaft 1 rotates, dust preventing component A3 comprises the dust ring A5 that more than two concentric interval is convexly equipped with, dust ring A5 can produce outside air-flow along with dust preventing component A3 rotates, prevent that ash content and cooling fluid from entering main shaft 1, and dust ring A5 is the projection tilting laterally in the utility model, when being rotated, dust ring A5 can produce larger air-flow, significantly strengthen the dust-proof effect of device.
When Digit Control Machine Tool or spindle of numerical control lathe 1 are worked, can exist employee to use air gun improper, the air-flow that air gun is produced enters main shaft 1 inside, or in the time that Digit Control Machine Tool or spindle of numerical control lathe 1 quit work, natural airflow can enter from gap between main shaft 1 and bearing block 2 with ash content and cooling fluid, in the time arriving dust ring A5, the air-flow that carries impurity can be subject to the acclivitous lateral surface of dust ring A5 and hinder, under the guiding on inclined-plane, carrying the air-flow of impurity can concentrate to the corresponding surface of dust ring A5 place face mobile, flow out main shaft 1 along corresponding surface, form a wind barrier, stop ash impurities afterwards to enter, special described wind barrier is formed on the gap between dust ring A5 end and corresponding surface, effectively stop the ash impurity that grades to enter main shaft 1 inside.
Angle between the medial surface of described dust ring A5 and its place plane is 115-150 degree; Angle between the medial surface of described dust ring B6 and its place plane is 115-150 degree.
If ash content and cooling fluid enter from the gap between dust ring A5 end and corresponding surface accidentally, the same dust ring B6 arranging on the corresponding surface of dust ring A5 place face can guide the air-flow that carries impurity to dust ring A5 medial surface, and between dust ring A5 medial surface and place plane, angle is beneficial to the air-flow that carries impurity and discharges main shaft along medial surface.Meanwhile, the centrifugal force producing when main shaft 1 rotates also contributes to impurity to throw away along inclined-plane.
In the time that main shaft 1 keeps flat and is out-of-operation, dust ring A5 and dust ring B6 and face angle, place can form a skewed slot (referring to Fig. 2), the ash that the drops on inclined-plane impurity that grades can be concentrated skewed slot bottom, and the centrifugal force producing when main shaft 1 rotates can throw away impurity unification.
The distance of the end of dust ring A5 and dust ring B6 place plane is 0.15-0.2mm; The distance of the end of dust ring B6 and dust ring A5 place plane is 0.15-0.2mm.
Angle between described dust ring A5 and dust ring B6 lateral surface and place plane is rounded down, and radius of corner is 0.2-0.4mm.
Angle between described dust ring A5 and dust ring B6 medial surface and place plane is rounded down, and radius of corner is 0.2-0.4mm.
Arranging of rounding is mainly in order to make two angles between face level and smooth, prevents that ash from grading Impurity deposition between angle.
