Referring to fig. 1, the bearing includes a front bearing 13 and a rear bearing 14, and the front bearing 13 and the rear bearing 14 are supported at front and rear ends of the shaft core 12, respectively. Correspondingly, the cooling ring comprises a first cooling ring 22 arranged on the periphery of the front bearing 13 and a second cooling ring 23 arranged on the periphery of the rear bearing 14, wherein the first cooling ring 22 is used for introducing a low-temperature refrigerant into the periphery of the outer ring of the front bearing 13 and rapidly cooling the front bearing 13 through the low-temperature refrigerant. The second cooling ring 23 is configured to introduce a low-temperature refrigerant into the outer circumference of the outer ring of the rear bearing 14, and to rapidly cool the rear bearing 14 by the low-temperature refrigerant.

During operation, a low-temperature refrigerant flows through the refrigerant channel inside the first cooling ring 22, and the first cooling ring 22 surrounds the front bearing 13, so that the front bearing 13 is cooled quickly, fully and uniformly. In addition, the structure of the first cooling ring 22 having a circular ring shape is simpler than that of a separate structure, and the connection of the coolant line in the cooling system 2 and the assembly of the first cooling ring 22 on the main spindle head 11 are facilitated.

The high-temperature-resistant silica gel realizes that the second cooling ring 23 is fixed, and can prevent the cold energy of the second cooling ring 23 from dissipating to the outside, thereby improving the cooling effect of the bearing.
In some embodiments, referring to fig. 1, in order to realize the fast automatic temperature adjustment of the spindle bearing, the machine tool spindle cooling device further includes a temperature sensor 3 and a temperature controller 4, the temperature sensor 3 is mounted on the spindle box 11 and is located at the periphery of the front bearing 13 and the rear bearing 14 for detecting the temperature of the front bearing 13 and the rear bearing 14 in real time, the temperature sensor 3 and the compressor are both connected with the temperature controller 4, and the compressor is a variable frequency compressor.
