The utility model discloses a kind of waterproof and dustproof structure for ball electric spindle, with reference to shown in Fig. 1 to Fig. 6, its
Include steel cylinder 1, rotor core 2 is equipped with the steel cylinder 1, the open-ended place of the steel cylinder 1 is provided with bearing block 3, the axle
Bearing 4 is provided with bearing 3, the rotor core 2 is extended to outside the steel cylinder 1 through the bearing 4, on the bearing block 3
The bearing plate 5 of annular is fixed with, is arranged on the rotor core 2 and is fixed with dust cap 6, the dust cap 6 is arranged in bearing
Pressing plate 5 and the first gap 61 is provided with therebetween, the top of the dust cap 6 extends and formed with flange 60 laterally, and institute
State and the second gap 62 is provided between the bottom of flange 60 and the top of bearing plate 5, the top of the bearing plate 5 is fixed with
Dust ring 7, the dust ring 7 are surrounded on the flange 60 and are provided with third space 63, the bottom of the dust ring 7 therebetween
And the recess 70 of annular is offered along the inwall of dust ring 7, is arranged on the rotor core 2 above the flange 60 and solid
Surely there is waterproof cover 8, the bottom of the waterproof cover 8 stretches out and is located at dust ring 7 formed with where umbrella-shaped portion 80, the where umbrella-shaped portion 80
Top and be provided with the 4th gap 71 therebetween, the first passage for delivery air is offered in the barrel of the steel cylinder 1
10, gas port 30 is offered in the bearing block 3, and one end of the gas port 30 is connected with first passage 10, the air guide
The other end in hole 30 extends to the top of bearing block 3, and the gas port 30 is corresponded on the bearing plate 5 and offers through hole
50, the bottom of the dust ring 7 offers the notch 72 for the through hole 50 to be connected with the recess 70, when described
In one passage 10 during injecting compressed air, air-flow is successively by gas port 30, through hole 50, notch 72, recess 70, third space 63
Outwards blowed with the 4th gap 71.
In above-mentioned waterproof and dustproof structure, the compressed air injected into first passage 10 forms air-flow, and the air-flow passes through successively
Cross gas port 30, through hole 50, notch 72, recess 70, the gap 71 of third space 63 and the 4th outwards blow, while between second
Gap 62 and first forms air pressure in gap 61, air-flow persistently blow effect under, effectively prevent moisture, mist of oil, dust etc.
Into inside electro spindle, the devices such as damage ball bearing, motor are avoided, substantially increase the service life of electro spindle.
In the present embodiment, the bottom of the where umbrella-shaped portion 80 offers the slit 81 of annular, when air-flow from the 4th gap 71 to
When blowing outside, air bag is formed at the slit 81.In the presence of the air bag, it can effectively prevent cutting fluid from entering electro spindle
It is interior.
In practical application, the width in the 4th gap 71 is more than third space 63, and the width of the third space 63 is big
In the second gap 62.According to self priming pump principle, under waterproof cover, dust cap rotate at a high speed with shaft core, the gap between two parts
During less than 0.2mm, rotary body will form self priming pump effect, and in the structure shown here, first, second, third gap will form self priming pump
Structure, the water in compressed air, oil, foreign matter are discharged, more preferably prevent the water, oil, foreign matter of outside from entering inside main shaft, be based on
Above-mentioned characteristic, because air-flow preferentially flows to the small position of resistance so that air-flow is preferentially with 360 degree equably from the 4th gap 71
Blowout, to prevent the cutting fluid of outside from entering inside main shaft, so as to strengthen dust-proof, waterproof action.
As a kind of preferred embodiment, the outside of the flange 60 is protruded formed with water conservancy diversion slopes 64, the water conservancy diversion slopes 64
Positioned at the lower end of flange 60, and the water conservancy diversion slopes 64 oliquely downward tilt.One effect of the water conservancy diversion slopes 64 is,
When there are moisture or mist of oil in the outside of flange 60, while flange 60 rotates at a high speed, water conservancy diversion slopes 64 can by moisture or
Person's mist of oil is to driveing at third space 63；Another effect of the water conservancy diversion slopes 64 is, when air-flow enters in recess 70,
Air-flow can preferentially be oriented to third space 63 by water conservancy diversion slopes 64 so that air-flow preferentially can be blown out from the 4th gap 71.
In order to improve interior waterproof dustproof effect, the bottom of the flange 60, which offers, is surrounded on the recessed of the dust cap 6
Groove 65, the top of the bearing plate 5 is formed with annular projection 51, and the annular projection 51 prolongs into the groove 65
Stretch.
In the present embodiment, dust cap 6 is screwed together on the bearing 4.The lateral wall of the flange 60 offers left-hand thread 66.
Because the direction of rotation of rotor core 2 is left-hand, when rotor core 2 drives dust cap 6 to rotate, left-hand thread 66 can produce outside drive
Power, so as to which the water in recess 70, mist of oil be taken out of, prevent water, mist of oil from concentrating in recess 70.
As a kind of preferred embodiment, the external diameter of the dust ring 7 is more than the external diameter of where umbrella-shaped portion 80, to make dust ring 7 and umbrella
The edge in shape portion 80 is in step-like.Based on the step-like structure so that the blowing direction of air-flow is partial to rotor core 2.
Further, the notch 72 on the dust ring 7 is kidney slot.
On this basis, formed with oliquely downward inclined inclined-plane 82 at the top edge of the where umbrella-shaped portion 80.The inclined-plane
82 effect is, when main shaft rotates in high speed, if cutting fluid is injected on waterproof cover 8, due to being produced when waterproof cover 8 rotates
Centrifugal force, cutting fluid can be thrown away so that cutting fluid is difficult to enter inside main shaft.
The disclosed waterproof and dustproof structure for being used for ball electric spindle of the utility model, it is on the basis of lasting blowout air-flow
On, moisture, mist of oil etc. are also prevented in several ways, effectively prevent damage electro spindle, there is preferable application prospect.
Simply the utility model preferred embodiment described above, is not limited to the utility model, all in this practicality
Modification, equivalent substitution or improvement made in new technical scope etc., should be included in the model that the utility model is protected
In enclosing.
