[0002] A machine tool is a machine tool used to manufacture and process metal or other materials. It is an indispensable equipment in modern manufacturing. The main function of a machine tool is to process raw materials or semi-finished products into the required shape and size through various cutting, grinding, drilling, milling and other operations.

[0003] Machine tool feet are an indispensable part of machine tool installation. They are usually located at the bottom of the machine tool to support and stabilize the machine tool. Since the existing feet for machine tools are generally made of metal materials and rubber pads are arranged on the lower surface of the metal base, the overall vibration prevention effect is poor. Some feet are equipped with shock-absorbing elements to buffer the force, but the shock-absorbing elements cannot be effectively limited, resulting in the shock-absorbing elements being easily damaged. Therefore, it is necessary to provide a foot for anti-vibration and anti-slip of machine tools to solve the above problems. Utility Model Content

[0025] The shock absorbing mechanism 5 includes a spring 505 , and the spring 505 is arranged at the inner center of the upper cover 3 .

[0026] Among them, the shock absorbing mechanism 5 also includes a socket 501, a limiting rubber column 502, a first annular rubber pad 503 and a second annular rubber pad 504. A slot 101 is provided at the center of the upper end surface of the base 1. The socket 501 is clamped in the slot 101. The limiting rubber column 502 is fixedly arranged at the center of the upper end surface of the socket 501. The first annular rubber pad 503 is arranged on the upper end surface of the socket 501. The upper end of the limiting rubber column 502 passes through the central circular hole of the first annular rubber pad 503 and extends to the inside of the spring 505. The spring 505 is arranged between the first annular rubber pad 503 and the second annular rubber pad 504. The slot 101 is provided to facilitate the installation and fixing of the socket 501. The limiting rubber column 502 is provided to facilitate the installation of the first annular rubber pad 503 and to limit the first annular rubber pad 503. At the same time, the limiting rubber column 502 can effectively limit the contraction of the spring 505.

[0027] Among them, annular grooves are provided on the opposite sides of the No. 1 annular rubber pad 503 and the No. 2 annular rubber pad 504, and annular plates are provided at both ends of the spring 505. The two annular plates are respectively inserted into the two annular grooves. A top plate 506 is fixedly provided on the upper end surface of the No. 2 annular rubber pad 504, and a support column 507 for connecting with the machine tool is provided in the center of the top plate 506. A through hole 301 is provided in the center of the upper wall of the upper cover 3, and the upper end of the support column 507 extends to the outside through the through hole 301. By arranging the No. 1 annular rubber pad 503 and the No. 2 annular rubber pad 504, they can be used as damping elements. When the support column 507 is squeezed by the vibration of the machine tool, the support column 507 squeezes the top plate 506 to shrink toward the inside of the upper cover 3, and the spring 505 shrinks. The No. 1 annular rubber pad 503 and the No. 2 annular rubber pad 504 absorb and transform vibration energy to ensure the vibration-proof ability of the machine tool.

[0028] Among them; the limiting telescopic rod 4 is arranged on the outside of the spring 505, the upper end of the limiting telescopic rod 4 is connected to the top plate 506, and the lower end of the limiting telescopic rod 4 is connected to the base 1.

The strip grooves are provided on the lower end surface of the rubber pad 2 to increase the anti-slip ability of the rubber pad 2.

[0030] Working principle: By setting the No. 1 annular rubber pad 503 and the No. 2 annular rubber pad 504, they can be used as damping elements. When the support column 507 is squeezed by the vibration of the machine tool, the support column 507 squeezes the top plate 506 to shrink toward the inside of the upper cover 3, and the spring 505 shrinks. The No. 1 annular rubber pad 503 and the No. 2 annular rubber pad 504 absorb and transform vibration energy to ensure the vibration-proof ability of the machine tool. By setting the limited telescopic rod 4, the shock absorbing mechanism 5 can be effectively limited to ensure the vertical expansion and contraction of the shock absorbing mechanism 5, thereby extending the service life of the shock absorbing mechanism 5.

[0031] Furthermore, by providing a card slot 101, it is convenient to install and fix the card seat 501, and by providing a limiting rubber column 502, it is convenient to install the No. 1 annular rubber pad 503 and limit the No. 1 annular rubber pad 503. At the same time, the limiting rubber column 502 can effectively limit the contraction of the spring 505. By providing a rubber pad 2, it can effectively play a role in noise reduction and pressure buffering. By inserting the annular protrusion 201 of the rubber pad 2 into the annular card slot 102, the stability of the rubber pad 2 is effectively guaranteed. By opening a strip notch on the lower end surface of the rubber pad 2, the anti-slip ability of the rubber pad 2 is increased.
