Description

  The present invention relates to an automatic lubrication device for a linear rail which is lubricated with oil in a stable manner so that the oil does not leak out.

  The conventional linear rail is shown, for example, in “Structure of Linear Rail” of Taiwan Utility Model Publication No. 404463. As shown in FIGS. 7 and 8, the rail (70) and the sliding block (50 ) And an automatic lubrication device, which are respectively provided at both ends of the sliding block (50), and the sliding block (50) is attached to the rail (70) so as to be capable of linear reciprocation. .

  The sliding block (50) is a block having a U-shaped cross section, and a ball groove (51) for installing a ball (not shown) is formed therein, and the automatic lubricating device has a U-shaped body ( 60), an opening (61) is formed on one side of the main body, a notch (611) corresponding to the ball groove (51) is formed on the inner wall of the opening (61), and the inside of the main body (60) A sponge (62) extending from the notch (611) to the outside is provided, and a dustproof cover (63) (referred to as a wiper in the industry) is provided at the opening (61).

  As shown in FIG. 8, when the sliding block (50) reciprocates in the rail (70), the sponge (62) containing lubricating oil comes into contact with the rail (70) to lubricate the rotating ball. .
