Embodiment Construction
[0024] Below in conjunction with accompanying drawing, the present invention is described in further detail:
[0025] Reference attached figure 1 and 2 , an electric spindle core cooling system of the present invention, a plurality of U-shaped cooling units 12 composed of straight-hole micro-channels are processed on the electric-spindle core 6, and the diameter of the straight-hole micro-channels is less than or equal to 3mm. A single U-shaped cooling unit 12 is composed of an inflow channel 5 , a return flow channel 8 and a connecting channel 7 located at the shaft core of the electric spindle near the front bearing. The processing position of the connecting channel 7 of a single U-shaped cooling unit 12 should avoid the interference fit between the inner ring of the front bearing and the shaft core 6 of the electric spindle. The connecting channel 7 is sealed by a plug 13 . The inlet of the inflow channel 5 and the outlet of the return channel 8 of each U-shaped cooling ...
