It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present utility model. In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.
[0020] As Figures 1 to 3 shown, the gap adjustment device of the numerically controlled boring and milling machine in this embodiment includes a guide rail 1 and a sliding block 2. The sliding block 2 is slidably installed at the upper end of the guide rail 1. Adjusting plates 3 are installed at the front and rear parts of the lower end of the sliding block 2. The adjusting plates 3 are used to adjust the gap between the sliding block 2 and the guide rail 1. Fixed plates 4 are installed at the front and rear ends of the guide rail 1 below the adjusting plates 3. Moving grooves 5 are arranged at the upper ends of the fixed plates 4. The moving grooves 5 are used for the adjusting bolt 7 to move along with the sliding block 2. Moving plates 6 are slidably installed below both fixed plates 4. An adjusting bolt 7 is installed through a through hole in the middle of the lower end of the moving plate 6. The adjusting bolt 7 is located inside the moving groove 5, and the upper end of the adjusting bolt 7 penetrates through the adjusting plate 3 through a threaded hole. By rotating the adjusting bolt 7, the adjusting bolt 7 can connect the moving plate 6 and the adjusting plate 3. As the adjusting bolt 7 rotates, the distance between the moving plate 6 and the adjusting plate 3 can be adjusted, realizing the adjustment of the gap between the sliding block 2 and the guide rail 1, avoiding unstable vibration when the sliding block 2 moves. An oiling assembly is installed outside the sliding block 2. The oiling assembly is used to apply oil to the surface of the guide rail 1 to reduce the friction when the guide rail 1 moves and reduce the wear of the guide rail 1 during use.
[0021] Specifically, top blocks 9 are installed at the included angle positions at the upper end of the moving plate 6. Installation grooves 10 are arranged at the upper ends of the top blocks 9. Rolling grooves 11 are arranged at the lower ends of the fixed plates 4 above the installation grooves 10. Ball bearings 12 are jointly installed between the installation grooves 10 and the rolling grooves 11. When the moving plate 6 and the adjusting plate 3 are connected by the adjusting bolt 7, the moving plate 6 contacts the rolling groove 11 at the lower end of the fixed plate 4 through the ball bearings 12. When the sliding block 2 drives the moving plate 6 to move, the ball bearings 12 roll inside the rolling groove 11, effectively reducing the friction when the moving plate 6 moves.
[0022] Furthermore, a locking nut 13 is installed on the surface of the adjusting bolt 7 above the adjusting plate 3. The setting of the locking nut 13 realizes the locking of the adjusting bolt 7, avoiding accidental rotation of the adjusting bolt 7 after the gap adjustment is completed.
[0023] Furthermore, on both sides of the upper ends of the moving plates 6 on both sides of the adjusting bolt 7, guide rods 14 are installed. The guide rods 14 are located inside the moving grooves 5, and the upper ends of the guide rods 14 penetrate through the adjusting plate 3. When the sliding block 2 drives the moving plate 6 to move, the sliding block 2 drives the moving plate 6 to move horizontally through the guide rods 14, avoiding directly driving the moving plate 6 by using the adjusting bolt 7 and preventing the adjusting bolt 7 from bending.
[0024] Furthermore, the oiling assembly includes an oil box 801 and an oiling block 802. The surface of the sliding block 2 above the guide rail 1 is equipped with an oil box 801. On both sides of the lower end of the oil box 801, oiling blocks 802 are installed. Oil holes are arranged at the lower ends of the oil box 801 above the oiling blocks 802. When the sliding block 2 moves, the lubricating oil inside the oil box 801 falls into the oiling blocks 802 through the oil holes. The lubricating oil is absorbed by the oiling blocks 802, and the oiling blocks 802 perform oiling treatment on the surface of the guide rail 1, playing a lubricating role in the movement of the sliding block 2, effectively delaying the generation of gaps between the guide rail 1 and the sliding block 2 due to wear. The oil box 801 needs to be filled with lubricating oil regularly. The oiling blocks 802 are made of cotton cloth or sponge materials and can be replaced regularly.
[0025] Furthermore, a connecting plate 15 is installed at the upper end of the sliding block 2, and connecting holes 16 are installed at the upper ends of the connecting plates 15. The moving parts are installed on the connecting plates 15 through the connecting holes 16.
[0026] The usage method of this embodiment is as follows: Use a tool to drive the adjusting bolt 7 to rotate. When the adjusting bolt 7 rotates, the adjusting plate 3 moves closer to the fixing plate 4 to achieve the adjustment of the gap between the sliding block 2 and the guide rail 1. After the adjustment is completed, install the locking nut 13 on the adjusting bolt 7. When the sliding block 2 moves on the guide rail 1, the sliding block 2 drives the moving plate 6 to move through the guide rod 14. The ball 12 inside the top block 9 on the moving plate 6 contacts the rolling groove 11 at the lower end of the fixing plate 4, reducing the friction force when the moving plate 6 moves. At the same time, the lubricating oil inside the oil box 801 falls into the oiling blocks 802 through the oil holes. The lubricating oil is absorbed by the oiling blocks 802, and the oiling blocks 802 perform oiling treatment on the surface of the guide rail 1, playing a lubricating role in the movement of the sliding block 2, effectively delaying the generation of gaps between the guide rail 1 and the sliding block 2 due to wear.
[0027] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
