It represents the development direction of modern machine tool control technology and is a typical mechatronics product.

[0003] A crossbeam assembly for a CNC machine tool with a publication number of CN203304900U is retrieved, comprising a crossbeam body and a ram, the ram being located in front of the crossbeam body; guide rail mounting seats are provided on both the front and rear vertical surfaces of the crossbeam body, and linear guide rails are installed on the guide rail mounting seats; an extension arm is provided on the ram, the extension arm passes over the top of the crossbeam body, and is connected to the linear guide rail on the guide rail mounting seat on the rear vertical surface of the crossbeam body through a slider installed on the extension arm. The design of the utility model improves the overall rigidity and strength of the crossbeam assembly and ensures the processing accuracy.

[0004] In view of the above-mentioned related technologies, the inventor believes that the existing CNC machine tool crossbeams are often installed on the machine tool through a mounting seat, but the mounting seat and the crossbeam are mostly fixedly connected, resulting in the inability to adjust the position of the mounting seat, so that the crossbeam can only be installed on machine tools of the same specification and cannot adapt to machine tools of various specifications. In addition, the height of the existing crossbeam cannot be adjusted, which cannot meet the relevant use requirements, resulting in certain limitations in its use. To this end, we propose a CNC machine tool crossbeam combination. Utility Model Content

[0005] In view of the above problems existing in the existing crossbeam assembly of CNC machine tools, the present utility model is proposed.

[0006] Therefore, the purpose of the utility model is to provide a CNC machine tool beam combination, which solves the problem that the existing CNC machine tool beams are often installed on the machine tool through a mounting seat, but the mounting seat and the beam are mostly fixedly connected, resulting in the inability to adjust the position of the mounting seat, so that the beam can only be installed on machine tools of the same specification and cannot adapt to machine tools of various specifications. In addition, the height of the existing beam cannot be adjusted and cannot meet the relevant use requirements, resulting in certain limitations during use.

[0007] In order to achieve the above purpose, the utility model provides the following technical solutions:
