[0002] In the field of mechanical processing, CNC machine tools are widely used. CNC machine tools include multiple components, among which the spindle box is an important component of the machine tool. The spindle in the spindle box is basically provided with a clamping component. When in use, the parts to be processed are installed through the clamping component. In processing, various shafts inside the spindle box need to rotate at high speed. The various shafts set inside the spindle box are generally meshed and rotated through gears. Lubricating oil is added to the bottom of the spindle box for lubrication to reduce the friction between the gears.

[0003] However, a large amount of heat is generated during the high-speed meshing and rotation of gears. This heat will cause the gears to expand, reducing the matching performance between the gears, and this heat will reduce the service life of the gears. The existing technology only fills the spindle box with lubricating cooling oil to cool it down. This setting will cool the gears, but long-term rotation will still cause the temperature of the gears to rise. Therefore, in order to further reduce the temperature of multiple gears during rotation, we have proposed a new CNC machine tool spindle box. Utility Model Content

[0023] A box body A201 and a box body B202 are arranged in the spindle box 2, and the box body A201 and the box body B202 are fixedly connected by bolts or other connection forms. A plurality of rotating shafts are arranged in the box body A201 and the box body B202, and gears are arranged on the plurality of rotating shafts in an interference fit manner. These gears are arranged in meshing engagement, and the cavity inside the box body B202 and the cavity inside the third protective box 8 are filled with lubricating cooling oil;

[0024] A first protective box 6 is fixedly arranged at the upper end of the box body A201, a second protective box 7 is connected to one side of the first protective box 6, an electric push rod 9 is arranged on one side of the second protective box 7, a third protective box 8 is arranged at the lower end of the electric push rod 9, a piston 15 is connected to the movable column at the lower end of the electric push rod 9, a liquid spraying pipe 10 is connected to the inside of the first protective box 6, a plurality of shunt pipes 11 are forked at one end of the liquid spraying pipe 10, a nozzle 12 is connected to the lower end of the shunt pipe 11, and the other end of the liquid spraying pipe 10 is connected to the cavity inside the lower end of the third protective box 8, the box body A201 is connected to the inner cavity of the third protective box 8, and the box body A202 is connected to the inner cavity of the third protective box 8, and the inner cavity of the third protective box 8 is connected to the inner cavity of the third protective box 8. A liquid suction pipe 13 is provided at the bottom end of the interior of 201 and the box body B202, and the other end of the liquid suction pipe 13 is connected to the cavity inside the lower end of the third protective box 8. A first check valve 14 is connected to the liquid suction pipe 13, and a second check valve 16 is connected to the liquid spray pipe 10. A plurality of nozzles 12 are fixedly located above the gears, and the plurality of nozzles 12 and the plurality of gears are arranged one by one. When the lubricating cooling oil in the liquid spray pipe 10 is sprayed out through the shunt pipe 11 and the nozzle 12, the lubricating cooling oil is directly sprayed on the gears, which further improves the cooling effect of the lubricating cooling oil on the gears.

[0025] One end of the suction pipe 13 is an oil suction port, and an oil suction nozzle is provided on the oil suction port and the oil suction nozzle is suspended on the bottom end of the box body B202. The other end of the suction pipe 13 is an oil outlet, and the oil outlet is located at the bottom end of the internal cavity of the third protective box 8, and is sealed between the piston 15 and the end walls around the third protective box 8, and the piston 15 is movably located in the third protective box 8.
