Abstract
A kind of high speed drill attacks owner's axle integral sealing safeguard structure, including shaft core, end bearing and rear end bearing before being respectively sleeved in the shaft core, the two ends of shaft core are separately installed with front-end of spindle lid and rear-end of spindle lid, the side of the front-end of spindle lid is connected with inlet suction port, it is characterised in that：The front-end of spindle lid is provided with inlet suction port junction can constitute sealing inner ring and sealed outer ring that the composition sealing structure that cooperates is provided with the outside of the curtain diversion ring of labyrinth structure, the preceding end bearing with front-end of spindle lid.The water smoke and greasy dirt that the present invention is produced drilling and tapping machine by the protecting wall formed by twice labyrinth structure in process of production are blocked in Bearing outer, and whole device good sealing effect, the use time of main shaft also refer to greatly be lifted.
Description
Technical field
The present invention relates to drilling and tapping machine manufacturing technology field, and in particular to a kind of high speed drill attacks owner's axle integral sealing protection knot
Structure.
Background technology
In recent years because communications industry is risen, 3C phone housing process requirements amount is big, so that high speed drilling and tapping machine tool is able to soon
Speed development.In order to reduce production cost, the competitiveness of enhancing enterprise in the market as far as possible, center machine is attacked using these high speed drills
User generally board can be arranged very intensive, and high speed drill attack center carry out metal cutting process when inevitably
Mist of oil can be produced, intensive arrangement as enterprise undoubtedly exacerbates the mist of oil aggregation of production scene.In process of production also can be through
Often occur because greasy dirt penetrates into inside main shaft, damaged the situation of high-speed spindle bearing.The main shaft used in this environment is universal
There is a situation where that service life is short, maintenance cost is high, as the critical function part at Zuan Gong centers, main shaft frequent breakage, sternly
Important place reduces production efficiency, adds production cost.Trace it to its cause is exactly that main axle structure under prior art is sealed in protection
Structure is defective in sealing, causes greasy dirt infiltration shaft core corrosion bearing in process, causes main shaft to damage.
The content of the invention
The purpose of the present invention is to overcome the defect of existing technology and not enough there is provided a kind of good seal performance, main shaft use time
Long high speed drill attacks owner's axle integral sealing safeguard structure.
To realize object above, technical solution of the invention is：A kind of high speed drill attacks the protection of owner's axle integral sealing
End bearing and rear end bearing before being respectively sleeved in structure, including shaft core, the shaft core, the two ends of shaft core are separately installed with main shaft
Drive end bearing bracket and rear-end of spindle lid, the side of the front-end of spindle lid are connected with inlet suction port, it is characterised in that：Before the main shaft
End cap is provided with inlet suction port junction can constitute the curtain diversion ring of labyrinth structure, the preceding end bearing with front-end of spindle lid
Outside be provided with cooperate composition sealing structure sealing inner ring and sealed outer ring.
Rack sleeve is socketed with the outside of the preceding end bearing and rear end bearing, is set between the rack sleeve and shaft core
There is rear bearing inner race gland, the rear bearing inner race gland is pressed together on rear end bearing by fixing nut.
Gear oil seal circle is provided with the inner hole wall of the rear bearing inner race gland.
The present invention compared with prior art, has the advantage that：
1st, front-end of spindle lid and curtain diversion ring group constitute the first line of defence into labyrinth structure in the present invention, the bits that the external world is entered
End and water smoke stop outside, and are blown out water smoke by the air-flow in inlet suction port, and are made up of sealing inner ring and sealed outer ring
Back-up ring side constitute second defence line, the water smoke entered from gap and dirt are blocked in front end Bearing outer, it is to avoid cooling
Water smoke brings Bearing inner into, causes grease to dilute and corrodes bearing, causes main shaft to damage.
2nd, present invention eliminates the bearing outer ring gland in conventional art, be integrally machined out by rack sleeve, it is only remaining after
End bearing inner ring is contacted with rear bearing inner race gland, and increases ring structure, effectively resistance in rear bearing inner race gland inner hole wall
Stop the greasy dirt penetrated into by nut, while also simplify structure, save processing cost.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
Fig. 2 is the partial enlarged drawing at A in Fig. 1.
In figure：Shaft core 1, preceding end bearing 2, rear end bearing 3, front-end of spindle lid 4, inlet suction port 5, curtain diversion ring 6, sealing
Inner ring 7, sealed outer ring 8, rack sleeve 9, rear bearing inner race gland 10, fixing nut 11, gear oil seal circle 12.
Embodiment
Below in conjunction with brief description of the drawings, the present invention is further detailed explanation with embodiment.
Referring to Fig. 1-Fig. 2, a kind of high speed drill is attacked in owner's axle integral sealing safeguard structure, including shaft core 1, the shaft core 1
The outside of end bearing 2 and rear end bearing 3 before being respectively sleeved on, the preceding end bearing 2 and rear end bearing 3 is socketed with rack sleeve 9,
Rear bearing inner race gland 10 is provided between the rack sleeve 9 and shaft core 1, the rear bearing inner race gland 10 passes through fixed spiral shell
Mother 11 is pressed together on rear end bearing 3, and gear oil seal circle 12, shaft core 1 are provided with the inner hole wall of the rear bearing inner race gland 10
Two ends be separately installed with front-end of spindle lid 4 and rear-end of spindle lid, the side of the front-end of spindle lid 4 is connected with inlet suction port 5
Logical, the front-end of spindle lid 4 is provided with the air curtain that can constitute labyrinth structure with front-end of spindle lid 4 with the junction of inlet suction port 5 and led
Ring 6 is flowed, the outside of the preceding end bearing 2 is provided with the sealing inner ring 7 and sealed outer ring 8 for the composition sealing structure that cooperates.
High speed drilling and tapping machine produces water smoke, in the shaft core 1 of high speed rotation when carrying out machining after high-pressure cooling water injection
On, upward air-flow is also easy to produce, these are accompanied with the cooling water smoke at bits end by by front-end of spindle lid 4 and air curtain guide ring 6
The air-flow that a part can be blocked during first of labyrinth protecting wall of composition and is blown out from inlet suction port 5 is blown out, it is remaining from
The cooling water smoke entered in gap can be blocked in the second labyrinth protecting wall being made up of sealing inner ring 7 and sealed outer ring 8,
Before cooling water mist thoroughly will be blocked in by the setting in twice defence line outside end bearing 2.Bearing outer ring pressure is incorporated at rear end bearing 3
The rack sleeve 9 of lid and the gear oil seal circle 12 on the inner hole wall of rear bearing inner race gland 10 can be prevented effectively from fixation
The greasy dirt penetrated into nut 11, it is to avoid mist of oil penetrates into bearing from thread gaps after condensing, pollutes bearing grease, causes bearing to damage
It is bad.
