[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Example: See Figure 1 The utility model provides a technical solution: a machine tool crossbeam base structure.

[0023] Among them, the bottom of the beam body 1 is fixedly connected to a base 2, the right side of the beam body 1 is fixedly connected to a connecting block 3, the left side of the beam body 1 is provided with a connecting groove 4, the top of the beam body 1 is provided with a guide rail groove 5, the front and back of the beam body 1 are penetrated by side windows 6, the center of the beam body 1 is fixedly connected to a reinforcing rib 7, and the edge of the reinforcing rib 7 is fixedly connected to a reinforcing plate 8.

[0024] In this embodiment, the base 2 extends from the front and back of the beam body 1 to increase the contact area between the bottom and the ground to maintain the stability of the entire beam body 1. The depth of the connecting groove 4 on the beam body 1 is the same as the thickness of the connecting block 3. There are multiple connecting blocks 3 evenly distributed, and the connecting blocks 3 and the beam body 1 are fitted on the front side without protruding. The connecting blocks 3 on other beam bodies 1 can be inserted into the connecting groove 4 on the beam body 1, and the connecting blocks 3 on the beam body 1 can also be inserted into the connecting groove 4 on the gas beam body 1. The two beam bodies 1 are placed side by side, and the right connecting block 3 on the left beam body 1 is inserted into the left side of the right beam body 1. In the connecting groove 4, the top connecting block 3 fits the top of the connecting groove 4, and the bottom connecting block 3 fits the bottom of the connecting groove 4 to ensure that the two beam bodies 1 are aligned. Use a welding tool to weld the connecting block 3 in the connecting groove 4. Both the front and back sides must be welded to splice the two beam bodies 1. By analogy, multiple beam bodies 1 can be welded according to the actual length requirements of the machine tool. The guide grooves 5 on the tops of the aligned beam bodies 1 will also be automatically aligned. The inside of the beam body 1 is hollowed out and connected by reinforcing ribs 7 and reinforcing plates 8. The strength structure of the entire beam body 1 is guaranteed by a minimum of material, and the side window 6 can observe the inner wall structure from the outside.

[0025] Therein, a plurality of guide rail grooves 5 are arranged in parallel on the top of the cross beam body 1 , and the guide rail grooves 5 are provided with oblique chamfers at the edge of the cross beam body 1 .

[0026] In this embodiment, a slider is installed in the guide groove 5, which moves by connecting the main shaft frame. The chamfer at the edge position expands the connection area to prevent slight misalignment of the beam body 1 during installation, causing the subsequent main shaft frame to move unsmoothly in the guide groove.

[0027] The crossbeam body 1 is integrally cast.

[0028] In this embodiment, a single crossbeam body 1 is integrally cast by a mold, and has high overall strength, good rigidity, and is not easy to deform. At the same time, the production speed is fast, which is convenient for mass production.

[0029] The center positions of the reinforcing rib 7 and the reinforcing plate 8 are hollow.

[0030] In this embodiment, the reinforcing rib 7 is circular in the center of the beam body 1 and connects the plates on the left and right sides of the beam body 1. The reinforcing plate 8 is fixedly connected with the M-shaped divergent edges to play a supporting effect and prevent the beam body 1 from deforming after long-term use. The reinforcing plate 8 will avoid the side windows 6 and is also for the convenience of casting. The hollowing out in the middle can reduce weight, reduce materials and thus reduce costs.

[0031] A threaded hole is provided on the surface of the connecting block 3 , and a cover plate 9 is installed on the outer side of the connecting block 3 .

[0032] In this embodiment, the cover plate 9 is fixed to the outside of the connecting block 3 and the connecting groove 4 by screwing screws into the threaded holes, so that the appearance of the beam body 1 is more beautiful, and at the same time, the welding points are protected from corrosion by the external environment.

[0033] Working principle: Place two beam bodies 1 side by side, insert the connecting block 3 on the right side of the left beam body 1 into the connecting groove 4 on the left side of the right beam body 1, the top connecting block 3 fits the top of the connecting groove 4, and the bottom connecting block 3 fits the bottom of the connecting groove 4, ensure that the two beam bodies 1 are aligned, use welding tools to weld the connecting block 3 in the connecting groove 4, and the guide groove 5 on the top of the beam body 1 will also be automatically aligned. The spindle frame adjusts the spindle position by sliding the slider in the guide groove 5. According to the required length of the beam body 1, the corresponding number of beam bodies 1 is increased, thereby freely adjusting the length of the beam body 1.

[0034] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
