Description
Technical field
The invention belongs to central water outlet automatic tool changing electrical spindle devices, are more particularly to a kind of central water outlet automatic tool changing electrical
Main shaft negative pressure dehumidifier protection against leakage structure.
Background technology
Central water outlet electro spindle its main shaft in operation process needs mesoporous water flowing, and is sprayed in shaft end handle of a knife, to make cutter
Cutter head cools down.It needs to be provided with Special rotary connector in main axle structure to complete this function, it is unavoidable in this structure link
A small amount of water droplet is there is also to leak, and these water droplets will produce water mist in main shaft high speed rotation, these water mists can be quickly in master
Sprawling inside axis can enter bearing, stator and other electrical detecting elements, to influence the normal operation of electro spindle and use the longevity
Life.
Invention content
In order to solve the above technical problem, the present invention provides a kind of central water outlet automatic tool changing electrical spindle negative pressure dehumidifier leakproofs
Protect structure.
In order to reach above-mentioned technique effect, technical scheme is as follows：
Central water outlet automatic tool changing electrical spindle negative pressure dehumidifier protection against leakage structure, including housing and be arranged in housing
One end of cooling-water duct and evacuation passageway, cooling-water duct is connect with water connector, the other end of cooling-water duct and rotation
Adapter connects, and is equipped with negative pressure cavity at the rotating contact face of cooling-water duct and rotary joint, negative pressure cavity and cooling-water duct with
It is connected at the rotating contact face of rotary joint, negative pressure cavity is located at around cooling-water duct, negative pressure cavity and evacuation passageway phase
Connection, evacuation passageway are connect with vacuum generator.
In some embodiments, housing is cylindrical shape.
Advantage is：The coolant liquid leaked at the cooling-water duct of the present invention and the rotating contact face of rotary joint is first
It is stored in negative pressure cavity, leakage fluid is discharged via evacuation passageway in time again for external vacuum generator, effectively to main shaft
Carry out protection against leakage；Negative pressure cavity has the function of buffering for the coolant liquid of leakage, prevents vacuum generator cannot in time will be cold
But liquid is extracted out and is damaged to equipment.
Description of the drawings
The present invention will be further described below with reference to the drawings.
Fig. 1 is the knot of the central water outlet automatic tool changing electrical spindle negative pressure dehumidifier protection against leakage structure of an embodiment of the present invention
Structure schematic diagram.
The title of corresponding component in figure represented by number：
1. housing, 2. cooling-water ducts, 3. evacuation passageways, 4. water connectors, 5. rotary joints, 6. vacuum generators,

Specific implementation mode
As shown in Figure 1, the present invention provides a kind of negative pressure dehumidifier protection against leakage structure of central water outlet automatic tool changing electrical spindle,
Including housing 1, cooling-water duct 2 and evacuation passageway 3 in housing 1.One end of cooling-water duct 2 is equipped with water connector 4, cooling
The other end of aquaporin 2 is connect with rotary joint 5, and rotary joint 5 is connect with main shaft 7.Cooling-water duct 2 and rotary joint 5
It is the leakage point of coolant liquid at rotating contact face.It is equipped with negative pressure cavity 8 at cooling-water duct 2 and the rotating contact face of rotary joint 5,
It is connected at negative pressure cavity 8 and cooling-water duct 2 and the rotating contact face of rotary joint 5, negative pressure cavity 8 is located at cooling-water duct 2
Around.Evacuation passageway 3 is connected with negative pressure cavity 8.Evacuation passageway 3 is connect with vacuum generator 6.Cooling-water duct 2 and rotation
The coolant liquid leaked at the rotating contact face of adapter 5 is first stored in negative pressure cavity 8, then is discharged by evacuation passageway 3.Negative pressure cavity
8 have the function of buffering for the coolant liquid of leakage, prevent vacuum generator 6 from cannot in time extract coolant liquid out and be made to equipment
At damage.
If rotary joint 5 has coolant liquid leakage, coolant liquid meeting at the rotating contact face with cooling-water duct 2 at work
It accumulates in negative pressure cavity 8, liquid enters inside lower part main shaft 7 in order to prevent, and the present invention is provided with evacuation passageway 3, when once
There are leakage liquid generation, external vacuum generator 6 to start to work, form negative pressure in negative pressure cavity 8, by leakage fluid by vacuumizing
Channel 3 is discharged, and thus effectively carries out protection against leakage to main shaft 7.
Above-described is only the preferred of central water outlet automatic tool changing electrical spindle negative pressure dehumidifier protection against leakage structure of the present invention
Embodiment without creative efforts, can also be made several for those of ordinary skill in the art
Modification and improvement, these are all within the scope of protection of the present invention.
