[0002] A guide rail is a groove or ridge made of metal or other materials that supports, fixes, and guides moving devices or equipment while reducing friction. Guide rails for CNC machine tools need to have certain guiding accuracy, accuracy retention, rigidity, and smooth low-speed movement. These are mainly determined by the geometric accuracy and contact accuracy of the guide rail, as well as its wear resistance, etc.

[0003] As shown in the prior art published in CN212886203U, although the prior art avoids excessive weight on the slider at the upper end of the guide rail, which could lead to uneven operation, by providing a guide rail and a convenient splicing device to prevent insufficient guide rail length, the prior art uses slots and buckles for connection and assembly. However, the assembled guide rail can still move up and down, which affects the stability and practicality of the guide rail. Utility Model Content

[0004] To overcome the aforementioned deficiencies of the prior art, this utility model provides a guide rail for CNC machine tools. Through the threaded connection of the connecting column and the fixing ring, the connecting column can be rotated outward to the connecting groove on the adjacent guide rail body, thereby connecting and fixing two adjacent guide rail bodies. This facilitates the operator to adjust the length of the guide rail body according to processing needs. Furthermore, the threaded connection between the connecting column and the connecting groove can effectively ensure the connection stability of the two adjacent guide rail bodies, thus solving the problems mentioned in the background art.

The connecting post 3 is threadedly connected to the fixing ring 4.

[0026] The operator moves the adjusting wheel through the through hole 8 to rotate the connecting column 3. The connecting column 3 is stably displaced outward by the threaded connection with the fixing ring 4 and gradually rotates into the connecting groove 5 on the adjacent guide rail body 1. Because the connecting column 3 has external threads 7 and the connecting groove 5 has internal threads 6, the connecting column 3 can be connected and fixed to the two adjacent guide rail bodies 1 by the threaded connection with the connecting groove 5. This makes it convenient for the operator to adjust the length of the guide rail body 1 according to the processing needs. Moreover, the threaded connection between the connecting column 3 and the connecting groove 5 can effectively ensure the connection stability of the two adjacent guide rail bodies 1.

[0027] To improve the ease of operation of connecting post 3, such as Figure 1-3As shown, the top of the guide rail body 1 near the connecting post 3 has a through hole 8, and the through hole 8 is connected to the fixing groove 2.
