[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0024] like Figure 1 - Figure 3 As shown, a CNC machine tool column with high stability and shock absorption function provided by the present embodiment includes a base 1, the lower end of the base 1 is provided with anti-slip grooves, which can effectively improve the stability of the base 1, an installation groove is opened at the upper end of the base 1, a buffer pad 13 is fixedly installed at the bottom end of the installation groove, a shock absorbing rod 2 is fixedly installed at the upper end of the buffer pad 13, a fixing plate 3 is fixedly connected to the top of the shock absorbing rod 2, four fastening holes 7 are opened on the fixing plate 3 and are distributed in a ring shape with the fixing plate 3 as the center, a connecting rod 4 is threadedly connected to the inside of the fastening hole 7, a pressing plate 12 is arranged at the bottom end of the shock absorbing rod 2, a fixing rod 11 is fixedly installed on the upper end of the pressing plate 12, a sliding rod 5 is movably connected to the top of the fixing rod 11, and a column body 6 is fixedly connected to the top of the sliding rod 5. The column body 6 has high strength, good firmness, high safety and a wide range of use, and a mounting seat 8 is movably connected to the top of the column body 6. The use of the mounting seat 8 allows the column body 6 to be installed and used with a machine tool.

[0025] like Figure 2 As shown, a center column 10 is fixedly connected to the inner center position of the column body 6, and a reinforcing rib 9 is fixedly connected to the outer surface of the center column 10. The reinforcing rib 9 has the advantages of high structural strength, large bearing capacity, strong stability, and small processing area. One end of the reinforcing rib 9 is fixedly connected to the inner wall of the column body 6. The reinforcing rib 9 is arranged in three groups, and the three groups of reinforcing ribs 9 are equidistantly arranged. The coordinated use of the center column 10 and the reinforcing rib 9 can effectively increase the use strength of the column body 6, and at the same time can also have the characteristic of low cost.

[0026] like Figure 1 and Figure 3 As shown, the sliding rod 5 passes through the fixed plate 3 at the top of the shock absorbing rod 2 and is connected to the column body 6. A spring 14 is sleeved on the outside of the sliding rod 5 between the fixed plate 3 and the pressure plate 12 to improve the buffering and shock absorbing effect of the column body 6. The outer diameter surface of the sliding rod 5 is movably connected to the inside of the top of the fixed rod 11, the bottom end of the fixed plate 3 is connected to the top of the spring 14, the bottom end of the fixed rod 11 is fixedly connected to the middle of the bottom end of the pressure plate 12, and the top of the pressure plate 12 is connected to the bottom end of the spring 14 to enhance the stability of the structure.

[0027] like Figure 3 As shown, the outer diameter of the sliding rod 5 is smaller than the inner diameter of the fixed rod 11 , and the surface of the sliding rod 5 is smooth, which can ensure that the sliding rod 5 can slide normally in the fixed rod 11 .

[0028] like Figure 3 As shown, the buffer pad 13 is located between the base 1 and the shock absorbing rod 2, which is used not only to stabilize the shock absorbing rod 2 and prevent it from sliding, but also to prevent the shock absorbing rod 2 from being damaged by friction between the base 1 and the shock absorbing rod 2.

[0029] The working principle and use process of this utility model:

[0030] When in use, first connect the column body 6 to the machine tool through the mounting seat 8, and stably support the column 1 through the cooperation of the shock-absorbing rod 2 and the column body 6. When the machine tool vibrates, the column body 6 will press down the sliding rod 5 when it is subjected to a large pressure, and the extrusion spring 14 will be compressed. The spring 14 will elastically contract, and at the same time, the sliding rod 5 will slide up and down in the fixed rod 11. The sliding rod 5 will damp the column body 6 in the shock-absorbing rod 2 through the spring 14, which can have a good buffering and shock-absorbing effect and prevent the column body 6 from being offset due to force. The cooperation of the central column 10 and the reinforcing ribs 9 set inside the column body 6 can effectively increase the use strength of the column body 6 and improve the stability of the device.
