Freeze the top of liquid bath 1 and liquid condensing system is set back, the totally enclosed type that this time liquid condensing system includes being sequentially connected by pipeline is compressed
Machine 5, air cooled condenser 6, evaporator a8.When cooling system works, the coolant in antifreeze liquid bath 1 is transported to through circulating pump 2
Main shaft 3, is cooled down to the bearing on main shaft 3, it is cooled after waste liquid then again through pipeline go back on defense jelly liquid bath 1 it is again sharp
With the temperature of the waste liquid of recovery is generally higher, can cause the temperature rapid increase of the coolant in antifreeze liquid bath 1, so logical
Liquid condensing system is commonly used back to cool down waste liquid, but existing time liquid condensing system is paid no attention to the cooling effect pole of waste liquid
Think, when the power increase of circulating pump 3, the waste liquid amount of recovery increases, and the coolant temperature in antifreeze liquid bath 1 is with cooling system
The growth of working time and lasting rise, can even exceed the warning of the coolant operating temperature set by cooling system sometimes
Line, so that cooling system is very poor to the cooling effect of main shaft.
The content of the invention
It is an object of the present invention to overcome the above-mentioned drawbacks of the prior art and provide a kind of cooling effect is excellent
Five axle milling machines spindle cooling device.
The purpose of the present invention can be achieved through the following technical solutions：

One capillary connection evaporator a, described evaporator a are placed in the coolant of antifreeze liquid bath.
At least two evaporation regions are provided with described evaporator a, disengagement area are added, so as to enhance to waste liquid
Condensation effect.
Thermometer provided with detection coolant temperature in described antifreeze liquid bath, thermometer connection warning system, alarm system
System collects the temperature signal that thermometer is fed back, when coolant temperature exceedes set warning line temperature, warning system report
It is alert.
Described coolant is the mixture of cooling oil and cooling water, wherein, cooling water accounts for coolant volume total amount
15%~25%.
The technological parameter of described circulating pump：Rated voltage is 220V, and rated power is 370W, and flow is 40L/min,
Lift is 40m.
Described circulating pump contacts aviation plug by a contactor, and the aviation plug is set up connects main current supply circuit all the way
Zero line, the zero line is arranged on the extension wire of aviation plug, and the zero line is connected directly to circulating pump, described main power supply
The zero line for being directly connected to circulating pump all the way is set up in loop, and the adjustment main contactor mode of connection is that monophase machine power supply is powered.
Compared with prior art, returning in liquid condensing system in the present invention combines work using inner evaporator with evaporator
Make, use multiple evaporation regions in evaporator again, the evaporation effect for treating evaporative medium is greatly strengthen, so as to effectively reduce
The operating temperature of coolant, enhances the cooling effect to main shaft in antifreeze liquid bath.
