Abstract
The utility model discloses a mechanical sealing device of a machine tool spindle. The mechanical sealing device of the machine tool spindle comprises a base, a pushing ring, a movable ring, a static ring, the spindle, a fastening screw, a connecting key, a spring, a straight pin, a flange sleeve and a box body. By the adoption of the device, when a machine tool drills a small hole at the high speed, cutting fluid and scrap iron are discharged from the rear end of an inner hole in the spindle. A part of cutting fluid and the small scrap iron permeate the interior of the spindle through gaps, permeation of oil scraps is prevented by means of the two tight fit planes of the static ring and the movable ring and two sealing rings, and therefore the sealing function when the spindle runs at the high speed is achieved. Meanwhile, the mechanical sealing device of the machine tool spindle is further provided with a cooling oil system, the problem that the service life of the sealing rings is short when the spindle runs at the high speed is effectively solved, and the reliability of the operation of the machine tool is improved.
