Sealing ring 12 is fitted tightly under gas pressure on rotation A axis 2.Excessive gas will be discharged by gas vent 10 in air,
The humidity that vapor sensor 9 detects at gas vent 10 in real time then notifies to alarm if humidity is excessive, is revealed to prevent cooling water.
The laser three-D unlimited rotary head mechanism of the present embodiment uses pneumatic shuttle and rubber seal to the sealing of cooling water
The mode for enclosing 12 compound seals, cooling water is limited in water route, it is not allowed to flow into other mechanisms.
Cooling water pass through passway for water, to cooled down through each component, process is as follows：
(1), cooling water enters passway for water from water inlet water route 11, by intake antrum 15 through the water inlet water in A shaft rotations 2.1
Road 11 flows into the first water cooling module 3 of the first speculum 4, is cooled down to rotation A axis 2 and the first water cooling module 3；
(2), cooling water enters the second speculum 6 after the outflow of the first water cooling module 3 by external first flexible water conduit 8.3

(3), cooling water enters the water outlet of C axis stator 8.1 from the second water cooling module 5 by external second flexible water conduit 8.5
Water route 14, after being cooled down to C axis stator 8.1, cooling water enters back into the water outlet water route 14 in A shaft rotations 2.1, finally by going out
Water cavity 18 flows into water cooling unit through the water outlet water route 14 on A axis stators end cap 2.2, completes a cooling cycle.
(4), cooling water circulation repeats the above steps (1)~(3), realizes the cycle to laser three-D unlimited rotary head mechanism
It is cooling.
In cooling water circulation cooling procedure, while by the way of 12 compound seal of pneumatic shuttle and rubber seal pair
The cooling water flowed through carries out moisture seal, and process is as follows：
The gas for having predetermined pressure is sent into gas path devices from two total air inlets 16, gas by total air cavity, through son into
The inflow of gas port 17 divides air cavity 13, so that air pressure in point air cavity 13 is more than the hydraulic pressure in passway for water, rubber seal 12 is made in air pressure
It is fitted tightly under on rotation A axis 2, prevents cooling water from entering and divide in air cavity 13.The air pressure such as divided in air cavity 13 is more than default
Pressure, then excessive gas be discharged from gas vent 10.As humidity is excessive at gas vent 10, then the notice of vapor sensor 9 alarm.
The air pressure divided in air cavity 13 can guarantee that rubber seal 12 is still fitted tightly over upon wear on rotation A axis 2, i.e.,
It is that rubber seal 12 can not be bonded completely too long because using, due to dividing air pressure in air cavity 13 to be more than hydraulic pressure, can also maintains one
Fixed sealing effect.

7. a kind of encapsulating method of laser three-D unlimited rotary head, which is characterized in that use laser three-D unlimited rotary head cold
But when water carries out coolant seal, while rubber seal (12) being fitted tightly on rotation A axis (2) using air pressure, realizes water
Cooling water is limited in passway for water by hermetic seal, it is not allowed to flow into other mechanisms.
8. the encapsulating method of laser three-D unlimited rotary head according to claim 7, which is characterized in that the moisture seal
Process is as follows：The gas for having predetermined pressure is sent into gas path device from two total air inlets (16), gas is by total air cavity, through son
Air inlet (17) inflow divides air cavity (13), and air pressure in a point air cavity (13) is made to be more than the hydraulic pressure in passway for water, rubber seal
(12) it is fitted tightly under gas pressure on rotation A axis (2), prevents cooling water from entering and divide in air cavity (13).
9. the encapsulating method of laser three-D unlimited rotary head according to claim 8, which is characterized in that the cooling water
Cooling procedure is as follows：
(1), cooling water enters passway for water from water inlet water route (11), by intake antrum (15) through the water inlet in A shaft rotations sub (2.1)
Water route (11) flows into the first water cooling module (3) of the first speculum (4), cooling rotation A axis (2) and the first water cooling module (3)；
(2), cooling water enters the second speculum after the outflow of the first water cooling module (3) by external first flexible water conduit (8.3)
(6) the second water cooling module (5), cooling second water cooling module (5)；
(3), cooling water enters going out for C axis stator (8.1) from the second water cooling module (5) by external second flexible water conduit (8.5)
Water water route (14), after cooling down C axis stator (8.1), cooling water enters back into the water outlet water route (14) in A shaft rotations sub (2.1), by being discharged
Chamber (18) flows into water cooling unit through the water outlet water route (14) on A axis stator end caps (2.2), completes a cooling cycle.
(4), cooling water circulation repeats the above steps (1)~(3), realizes cold to the cycle of laser three-D unlimited rotary head mechanism
But.
10. the encapsulating method of laser three-D unlimited rotary head according to claim 8, which is characterized in that divide air cavity (13)
In air pressure be more than preset pressure when, by gas vent (10) be discharged excessive gas；When humidity is excessive at gas vent (10), aqueous vapor passes
Sensor (9) notice alarm.
