Abstract
The utility model proposes a kind of grinding machine spindle high pressure air seal structure, main shaft seal is realized using the air curtain of pressure-air generation is dried；Realize and thoroughly stop the purpose that steam etc. enters in main spindle box, reach that main shaft is 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 on the side wall of main spindle box end cap and offers an inlet channel, 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 utility model 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 with rubber seal to realize main shaft seal in main spindle box rear and front end；This sealing means are excellent
Point is that simple in construction, cost is low, 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
The gap that main shaft surface increases main shaft and rubber seal is destroyed, 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.
Utility model content
The utility model proposes a kind of grinding machine spindle high pressure air seal structure, the air curtain produced using dry pressure-air is come real
Existing main shaft seal；Realize and thoroughly stop the purpose that steam etc. enters in main spindle box, reach that main shaft is fully sealed, and without periodically
Safeguard and change sealing ring, reduce maintenance cost.
Technical solutions of the utility model are 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, compared with prior art, the utility model has the following advantages that the utility model：
1st, the utility model accesses high-pressure air source by opening up inlet channel on the side wall of main spindle box end cap, and high pressure is empty
Chamber is full of front-end of spindle die cavity, is discharged from main spindle box and gap of main reinforcement, into air and takes and wraps up in the discharge of spindle-type intracavitary steam, together
When produce high velocity air in main spindle box and gap of main reinforcement formation protection air curtain, realize main shaft seal, reach that isolation steam etc. enters
Purpose, protect the precision components such as main shaft from steam corrosion.
2nd, sealed using pressure-air, realize the complete isolation 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
, below will be to embodiment in order to illustrate more clearly of the utility model embodiment or technical scheme of the prior art
Or the accompanying drawing used required in description of the prior art is briefly described, it should be apparent that, drawings in the following description are only
It is some embodiments of the present utility model, for those of ordinary skill in the art, is not paying the premise of creative work
Under, other accompanying drawings can also be obtained according to these accompanying drawings.
Fig. 1, is structural representation of the present utility model；
Embodiment
The technical scheme in the utility model embodiment will be clearly and completely described below, it is clear that described
Embodiment is only a part of embodiment of the utility model, rather than whole embodiments.Based on the implementation in the utility model
Example, the every other embodiment that those of ordinary skill in the art are obtained under the premise of creative work is not made is belonged to
The scope of the utility model protection.
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, has passage 6 between airtight seal 5 and the front end face of main spindle box end cap 2.For convenience of high-pressure air source access,
One unidirectional quick connector 1 is inserted on the inlet channel 3 by the utility model, and the high-pressure air source passes through the unidirectional fast grafting
First 1 connects 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, air-flow is further isolated from by the air formation disturbance in labyrinth ring 7
Outside main shaft installation cavity, air-flow can only pass through the passage 6 between airtight seal 5 and the front end face of main spindle box end cap 2 and main shaft
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
It is installed with a cavity 8 between the madial wall of lid, gases at high pressure enter after the cavity can be to the longitudinal surface A and lower horizontal stroke of airtight seal
To face B formation squeeze pressures 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.
Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model
Within the spirit and principle of utility model, any modification, equivalent substitution and improvements made etc. should be included in the utility model
