Abstract
The present invention proposes a kind of grinding machine spindle high pressure air seal structure, and main shaft seal is realized using the air curtain for drying pressure-air generation；Realize thoroughly stopping the purpose that steam etc. enters in main spindle box, reach main shaft and be fully sealed, and sealing ring is changed without periodic maintenance, reduce maintenance cost.The grinding machine spindle high pressure air seal structure, it is included in and an inlet channel is offered on the side wall of main spindle box end cap, the inlet channel is connected with a high-pressure air source, an airtight seal is equipped between the madial wall and front-end of spindle side wall of the main spindle box end cap, has passage between the front end face of airtight seal and main spindle box end cap.
Description
Technical field
The invention belongs to machine tool technology field, more particularly to grinding machine spindle high pressure air seal structure.
Background technology
Main spindle box is stretched out in the main shaft front and back end part of grinding machine, space is there is between main shaft side wall and box body hole, to prevent
The outer air containing dust of case enters, and the coupling part for generally requiring the end cap in main shaft and main spindle box body sets sealing structure,
Whether grinding machine spindle sealing is good, directly affects Main Shaft Service Life.
Conventional master spindle sealing is to realize main shaft seal in main spindle box rear and front end rubber seal；This sealing means are excellent
Point is simple structure, low cost, has the disadvantage that maintenance period is short and frequency of maintenance is high, short life；And contain iron filings and heavily fortified point in grinding
The emery wheel cooling water of hard emery wheel break flour can be attached between rubber seal and main shaft, and emery wheel break flour can wear and tear when main shaft runs at high speed
Destruction main shaft surface increases the gap of main shaft and rubber seal, and main shaft surface causes main shaft and rubber seal by long term wear
Between gap width when reaching certain numerical value steam will enter main spindle box inner main axis seal failure, cause the precisions such as main shaft and bearing
Part influences grinding machine precision by steam corrosion.
The content of the invention
The present invention proposes a kind of grinding machine spindle high pressure air seal structure, and master is realized using the air curtain for drying pressure-air generation
Sealing；Realize thoroughly stopping the purpose that steam etc. enters in main spindle box, reach main shaft and be fully sealed, and without periodic maintenance
Sealing ring is changed, maintenance cost is reduced.
Technical solution of the present invention is as follows：
Grinding machine spindle high pressure air seal structure, offers an inlet channel, the inlet channel on the side wall of main spindle box end cap
Connected with a high-pressure air source, an airtight seal is equipped between the madial wall and front-end of spindle side wall of the main spindle box end cap,
There is passage between the front end face of airtight seal and main spindle box end cap.
Further, a unidirectional quick connector is inserted on the inlet channel, and the high-pressure air source is unidirectional fast by this
Connection-peg is connected with inlet channel.
Further, the airtight seal is provided with labyrinth ring, and the labyrinth ring is affixed on front-end of spindle lateral surface.
Further, the cross section of the airtight seal is L-shaped, in the lower horizontal face of airtight seal and main spindle box end cap
Madial wall between be installed with a cavity.
Further, the airtight seal is the airtight seal of nylon.
By above description, the present invention compared with prior art, the invention has the advantages that：
1st, the present invention accesses high-pressure air source by opening up inlet channel on the side wall of main spindle box end cap, and high pressure cavity fills
Full front-end of spindle die cavity, discharges from main spindle box and gap of main reinforcement, into air and takes and wraps up in steam discharge in main shaft die cavity, while producing
Raw high velocity air forms protection air curtain in main spindle box and gap of main reinforcement, realizes main shaft seal, reaches the mesh of the entrance such as isolation steam
, the precision components such as main shaft are protected from steam corrosion.
2nd, sealed using pressure-air, realize the isolation completely of steam, and it is different in conventional seals mode, without regular
Dismounting, replacing rubber seal, improve production efficiency, reduction maintenance cost.
Brief description of the drawings
In order to illustrate more clearly about the embodiment of the present invention or technical scheme of the prior art, below will be to embodiment or existing
The accompanying drawing to be used needed for having technology description is briefly described, it should be apparent that, drawings in the following description are only this
Some embodiments of invention, for those of ordinary skill in the art, on the premise of not paying creative work, can be with
Other accompanying drawings are obtained according to these accompanying drawings.
Fig. 1, is structural representation of the invention；
Specific embodiment
The technical scheme in the embodiment of the present invention will be clearly and completely described below, it is clear that described implementation
Example is only a part of embodiment of the invention, rather than whole embodiments.Based on the embodiment in the present invention, this area is common
The every other embodiment that technical staff is obtained under the premise of creative work is not made, belongs to the model of present invention protection
Enclose.
Reference picture 1, grinding machine spindle high pressure air seal structure offers an inlet channel 3 on the side wall of main spindle box end cap 2,
The inlet channel 3 is connected with a high-pressure air source, is equipped between the madial wall and the front end side wall of main shaft 4 of the main spindle box end cap 2
One airtight seal 5, there is passage 6 between the front end face of airtight seal 5 and main spindle box end cap 2.Accessed for convenience of high-pressure air source,
Be inserted in one unidirectional quick connector 1 on the inlet channel 3 by the present invention, and the high-pressure air source passes through the unidirectional quick connector 1
Connected with inlet channel.The high-pressure air source can produce the dry air of certain pressure.
Reference picture 1, the airtight seal 5 is provided with labyrinth ring 7, and the labyrinth ring 7 is affixed on the front end outer side face of main shaft 4.
When pressure-air enters in end cap, under main shaft drive, the air in labyrinth ring 7 forms disturbance, is further isolated from air-flow
Outside main shaft installation cavity, air-flow can only be by the passage 6 and main shaft between the front end face of airtight seal 5 and main spindle box end cap 2
Gap between main spindle box is discharged in air, further lift-off seal performance.
Reference picture 1, the cross section of the airtight seal 5 is L-shaped, at lower horizontal face B and the main spindle box end of airtight seal 5
A cavity 8 is installed between the madial wall of lid, gases at high pressure can be to the longitudinal surface A of airtight seal and lower horizontal stroke after entering the cavity
Squeeze pressure is formed to face B so that airtight seal 5 is extruded to the direction of main shaft installation cavity, so as to improve sealing effectiveness.This implementation
In example, the airtight seal of nylon is preferably used in the airtight seal 5.
Presently preferred embodiments of the present invention is the foregoing is only, is not intended to limit the invention, it is all in essence of the invention
Within god and principle, any modification, equivalent substitution and improvements made etc. should be included within the scope of the present invention.
