To the problems referred to above, the purpose of the utility model provides a kind ofly can reduce heat that the electric main shaft operation that is assemblied on the lathe produces, and can prolong the electric main shaft of the band cooling device in electric main shaft service life.
For achieving the above object, the utility model adopts following technical scheme:
A kind of electric main shaft with cooling device, said electric main shaft comprises main shaft, rotor, stator, water proof cover, sleeve; Said rotor is set on the said main shaft, and said stator is set on the said rotor, and said water proof cover is set on the said stator;
The lateral surface of said water proof cover offers the water channel groove that supplies coolant flow, and said sleeve is sticked on the said lateral surface of water proof cover, and the two ends of said water channel groove are respectively arranged with cooling fluid inlet and the cooling liquid outlet that is positioned on the said sleeve.
Further, said water proof cover and said sleeve between be provided with sealing ring.
Further, be positioned at water channel groove that said water proof puts structure twist.
Further, the thickness of said sleeve is greater than the thickness of said water proof cover.
Further, pass through epoxy encapsulation between said stator and the said water proof cover.
Further, said cooling fluid inlet and said cooling liquid outlet are equiped with water pipe head respectively.
Further, the material of said water proof cover, said sleeve and said water pipe head is stainless steel.
Further, said water pipe head is welded on cooling fluid porch and cooling liquid outlet place respectively.
Further, said electric main shaft is used for lathe.
Further, be equiped with at least one electric main shaft on the said lathe.
The utility model is owing to adopt above technical scheme; It has the following advantages: 1, the utility model is owing to be equiped with cooling device on electric main shaft; Therefore the electric main shaft of the described band cooling device of the utility model can reduce the heat that electric main shaft operation produces, and prolongs electric main shaft service life.2, the utility model is owing to the lateral surface that the water proof cover is set directly at stator, and this water proof overlaps the close with stator, therefore can further improve the cooling effect of electric main shaft.3, the utility model water channel groove of adopting water proof to put is set to helical structure, therefore can reduce the heat that electric main shaft operation produces greatly.The utility model can be widely used in lathe especially on the lathe.
Description of drawings
Fig. 1 is the structural representation of electric spindle motor of the band cooling device of the utility model.
The specific embodiment
For the purpose, technical scheme and the advantage that make the utility model is clearer,, the utility model is further elaborated below in conjunction with accompanying drawing and embodiment.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
As shown in Figure 1, the utility model provides a kind of electric main shaft with cooling device, and electric main shaft comprises main shaft 1, rotor 2, stator 3, water proof cover 4, sleeve 5; Rotor 2 is set on the main shaft 1, and stator 3 is set on the rotor 2, and water proof cover 4 is set on the stator 3;
The lateral surface 41 of water proof cover 4 offers the water channel groove 42 that supplies coolant flow; Sleeve 5 is sticked on the lateral surface 41 of water proof cover 4, and the two ends of water channel groove 42 are respectively arranged with cooling fluid inlet (not shown) and the cooling liquid outlet (not shown) that is positioned on the sleeve 5.
In order to add the degree of being connected firmly of each parts in the forceful electric power main shaft, be provided with the sealing ring (not shown) between water proof cover 4 and the sleeve 5, and pass through epoxy encapsulation between stator 3 and the water proof cover 4.
In order further to optimize radiating effect and the service life that prolongs electric main shaft, the structure optimization of the water channel groove 42 of the utility model is a helical structure.
As a kind of optimal technical scheme, the thickness of sleeve 5 is greater than the thickness of water proof cover 4, so the cooling fluid in the water proof cover 4 is less apart from the distance of stator 3, and cooling effect is further optimized.
For the ease of the circulate of cooling fluid, cooling fluid inlet and cooling liquid outlet are equiped with the water pipe head (not shown) respectively.
In order to prevent the service life of water proof cover 4 and sleeve 5 corrosion and damage, the electric main shaft of prolongation, the material of water proof cover 4, sleeve 5 and the water pipe head of the utility model all is preferably stainless steel.In the present embodiment, water pipe head is welded on cooling fluid porch and cooling liquid outlet place respectively.
