Abstract
The utility model discloses a high-precision machine tool hydrostatic guideway double-layer sealing oil receiving device, and belongs to the technical field of machine tool accessories. The oil receiving box is in an inward-concave shape and is installed at the lower end of a vertical knife rest body through a bolt. A groove is formed in the outer flange of the oil receiving box. A rubber sealing ring is installed inside the groove. The outer edge of the oil receiving box is flush with the outer edge of the vertical knife rest body. An inner hole of the oil receiving box is the same as a ram in appearance. A groove is formed in the position below the side end of the inner flange of the oil receiving box. A silica gel sealing ring is installed inside the groove. An adjusting strip is arranged at the lower end of the side end of the inner flange of the oil receiving box. A first-layer sealing pressing block is installed at the lower end of the adjusting strip and installed at the lower end of the inner flange of the oil receiving box. A groove is formed in the lower end of the inner side of the first-layer sealing pressing block. A silica gel sealing ring is installed inside the groove. The lower end of the first-layer sealing pressing block is provided with a second-layer sealing pressing block which is installed on the first-layer sealing pressing block through a bolt. The lower end of the second-layer sealing pressing block is provided with a scraping plate. The high-precision machine tool hydrostatic guideway double-layer sealing oil receiving device is used in the sealing structure of a hydrostatic knife rest, and sealing reliability of the hydrostatic knife rest is ensured.
Description
Technical field
