The outside of spindle motor installation site is equipped with air inlet pipe in the air inlet, and one end of air inlet pipe is goed deep into cavity.
Preferably, the spindle motor is included cooling fan, is blown on the wind direction of the cooling fan.
Preferably, the air inlet pipe other end stretches out ram shell upper end, and is connected with conveying gas blower.
Preferably, ram shell upper end is equipped with gas vent, can also install exhaust pipe, the row in the venthole
Air pipe sleeve is on spindle motor.
The utility model has the advantages that present invention discloses a kind of gantry main shafts to force cooling structure, the peace of shaft coupling is made by mounting plate
Holding position forms closed cavity, and wind is sent into the cavity further through air inlet pipe, keeps the gas exchanges in cavity more uniform,
And be discharged by venthole, it can be accelerated in spindle motor work by high temperature by the included scattered high-temperature gas fan of spindle motor
Gas is detached from cavity, accelerates the air velocity in ram, to shaft coupling, spindle motor and ram shell are quickly dissipated
Heat can also will be completely cut off by being set with exhaust pipe on spindle motor between high-temperature gas and ram, reduce high temperature to cunning
The influence of pillow, the deformation for preventing ram shell from generating by overheat influence the machining accuracy of Z axis；The configuration of the present invention is simple makes
With convenient, in quickening ram air velocity, radiating efficiency is improved, guarantees the machining accuracy of Z axis.
