[0032] Reference Figure 1 - Figure 2 , an embodiment provided by the utility model: a precision mechanical square support beam, comprising a main beam plate 1, a positioning rod 2 is fixedly connected to the upper surface of the main beam plate 1, a mounting plate 3 is fixedly connected to the upper surface of the main beam plate 1, a reinforcing plate 4 is fixedly connected to the outer wall of the mounting plate 3, a fixing bolt 5 is arranged inside the reinforcing plate 4, the outer wall of the fixing bolt 5 is arranged inside the mounting plate 3, a sliding groove 6 is opened inside the main beam plate 1, a special-shaped positioning plate 7 is slidably connected to the inside of the main beam plate 1, a slider 8 is fixedly connected to the outer wall of the special-shaped positioning plate 7, the outer wall of the slider 8 is slidably connected to the inside of the main beam plate 1, a fixing bolt 2 9 is arranged inside the special-shaped positioning plate 7, the outer wall of the fixing bolt 2 9 is arranged on the inner wall of the main beam plate 1, and an extension component is arranged on the outer wall of the main beam plate 1;

[0033] Specifically, firstly, the main beam plate 1 and the workpiece are accurately positioned by the positioning rod 2 to ensure that the relative position between the main beam plate 1 and the workpiece is accurate, and then the main beam plate 1 and the workpiece are tightly fixed together with the fixing bolt 5. In order to ensure the stability of the fixation, the connection part is also strengthened by the reinforcing plate 4 to further improve the overall strength. Then, according to the size of the guide rail, the special-shaped positioning plate 7 is pulled for adjustment. The special-shaped positioning plate 7 can drive the slider 8 to slide in the slide groove 6 inside the main beam plate 1, so as to achieve flexible adjustment. When it is adjusted to the appropriate size, the special-shaped positioning plate 7 and the main beam plate 1 are fixed by the fixing bolt 2 9. At the same time, the fixing bolt 2 9 can also ensure that the special-shaped positioning plate 7 and the guide rail are also tightly fixed, thereby achieving a stable connection.

[0034] Reference Figure 3- Figure 4 The extension assembly includes a left beam plate 10 and a right beam plate 11. The inner wall of the left beam plate 10 is slidably connected to the outer wall of the main beam plate 1, and the inner wall of the right beam plate 11 is slidably connected to the outer wall of the main beam plate 1. The upper surfaces of the left beam plate 10 and the right beam plate 11 are fixedly connected with a mounting plate 2 12. The internal thread of the mounting plate 2 12 is connected with a fixing bolt 1 5. Both ends of the main beam plate 1 are fixedly connected with a tenon 15.

The alternately arranged reinforcing ribs 13 and 14 form a supporting structure on the inner wall of the main beam 1, which effectively disperses the stress generated by the external load, and not only enhances the inner wall strength of the main beam 1, but also effectively improves the stiffness of the entire beam, thereby ensuring the stability and safety of the structure.

[0038] Working principle: When a precision mechanical square support beam is needed, firstly, the main beam plate 1 and the workpiece are positioned by the positioning rod 2, and then the main beam plate 1 and the workpiece are fixed by the fixing bolt 5.
