Description

Technical Field

[0001] This utility model relates to the field of CNC machine tool technology, specifically to a crossbeam structure for a CNC machine tool. Background Technology

[0002] The crossbeam of a CNC machine tool is an important load-bearing structural component, responsible for supporting other parts of the machine tool and affecting machining accuracy. The crossbeam is a key load-bearing component of CNC machine tools (such as CNC gantry milling machines), responsible for supporting the weight of other components such as the ram and milling head, and bearing the action of cutting forces during machining.

[0003] During use, the crossbeam is installed horizontally on the upper part of the machine frame. In order to reduce the weight of the equipment, holes are made inside the crossbeam. Usually, square or cross openings are made in the middle of the crossbeam to reduce the weight of the equipment while increasing the support force. However, during the process of making the holes, the square or cross openings are subjected to oblique or lateral pressure, which will cause lateral deformation and thus affect the service life of the crossbeam. Therefore, we propose a crossbeam structure for CNC machine tools. Utility Model Content

[0004] To address the shortcomings of existing CNC machine tool beam structures, this utility model provides a beam structure for CNC machine tools. The beam body has a circular reinforcing rib mounted on its inner side via an inner mounting plate. The inner mounting plate is welded between the beam body and the circular reinforcing rib, improving structural stability. Furthermore, the circular reinforcing rib is circular in shape, allowing for pressure relief through its arc-shaped structure when subjected to pressure from different directions, thereby enhancing the overall pressure resistance of the equipment and solving the problems mentioned in the background art.

[0005] This utility model provides the following technical solution: a crossbeam structure for a CNC machine tool, including a crossbeam body, an inner mounting plate installed inside the crossbeam body, a circular reinforcing rib welded to the middle of the inner mounting plate, circular holes equally spaced on the outside of the inner mounting plate, and an inner support movably sleeved inside the circular reinforcing rib.

[0006] Preferably, a first reinforcing rib is welded to the inner side of the main body of the crossbeam, and the first reinforcing rib is snapped into the interior of the inner mounting plate.

[0007] Preferably, a reinforcing rod is installed inside the circular hole, and the reinforcing rod is circular.

[0008] Preferably, the inner mounting plate is fixed with second reinforcing ribs on both sides. The second reinforcing ribs are triangular in shape and are arranged at equal intervals on both sides of the inner mounting plate. At the same time, the inner side of the second reinforcing ribs is welded to the outside of the circular reinforcing ribs.

[0009] Preferably, the circular reinforcing ribs are circular, and the inner mounting plates are arranged at equal intervals outside the circular reinforcing ribs.

[0010] Preferably, six sets of diagonal bracing plates are installed at equal intervals on the outside of the inner brace, and a support plate is installed inside the diagonal bracing plate by means of spring steel.

[0011] Compared with the existing beam structure of CNC machine tools, this utility model has the following advantages:

[0012] 1. The crossbeam structure of this CNC machine tool is installed between the crossbeam body and the circular reinforcing rib via an inner mounting plate. The circular reinforcing rib is circular and can distribute pressure in different directions, ensuring the overall compressive strength of the circular reinforcing rib. A second reinforcing rib is fixed to the inner side of the inner mounting plate and welded to the outside of the circular reinforcing rib. The second reinforcing rib is triangular, which improves the overall compressive strength of the second reinforcing rib and prevents the inner mounting plate from being damaged by pressure. This improves the overall compressive strength of the equipment and extends its service life.

[0013] 2. The crossbeam structure of this CNC machine tool has an inner support and a support plate installed inside the circular reinforcing rib. The support plate can expand and contract inside the inner support to ensure stability when the inner support and support plate are installed inside the circular reinforcing rib. The circular reinforcing rib improves the compressive strength in different directions. After the inner support and support plate are installed inside the circular reinforcing rib, the inner support and support plate further improve the compressive strength inside the circular reinforcing rib, thus further extending the service life of the equipment during use.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 A crossbeam structure for a CNC machine tool includes a crossbeam body 1. An inner mounting plate 3 is installed inside the crossbeam body 1, between the crossbeam body 1 and a circular reinforcing rib 4. The inner mounting plate 3 improves the supporting force. A circular reinforcing rib 4 is welded and installed in the middle of the inner mounting plate 3. The circular reinforcing rib 4 is circular and can withstand pressure in different directions, and can also relieve pressure in different directions, thereby improving the service life of the equipment. Circular holes are equally spaced on the outside of the inner mounting plate 3. An inner support 6 is movably sleeved inside the circular reinforcing rib 4. The inner support 6 is installed on the inner side of the circular reinforcing rib 4, and the inner support 6 adopts an oblique support method to improve the overall compressive strength of the circular reinforcing rib 4.

[0021] Please see Figure 1 The inner side of the main body of the crossbeam 1 is welded with a first reinforcing rib 2. The first reinforcing rib 2 is snapped into the inside of the inner mounting plate 3. By having the first reinforcing rib 2 on the inner side of the main body of the crossbeam 1, the overall strength of the main body of the crossbeam 1 is improved. At the same time, after the first reinforcing rib 2 is installed on the inner side of the main body of the crossbeam 1, the first reinforcing rib 2 guides the installation of the inner mounting plate 3, ensuring the stability of the inner mounting plate 3 when it is installed on the inner side of the main body of the crossbeam 1.

[0022] Please see Figure 4 A reinforcing rod 5 is installed inside the round hole. The reinforcing rod 5 is circular and has a round hole on the inner side of the inner mounting plate 3. The round hole reduces the weight of the structure, so that the structure can play a role in weight reduction while ensuring support.

[0023] Please see Figure 2The inner mounting plate 3 has two fixed second reinforcing ribs 8 on both sides. The second reinforcing ribs 8 are triangular and are arranged at equal intervals on both sides of the inner mounting plate 3. The inner side of the second reinforcing ribs 8 is welded to the outside of the circular reinforcing rib 4. By having second reinforcing ribs 8 on both sides of the inner mounting plate 3, the inner mounting plate 3 is controlled to be sequentially fitted onto the outside of the circular reinforcing rib 4. The triangular structure of the second reinforcing ribs 8 reinforces the connection between the inner mounting plate 3 and the circular reinforcing rib 4, improving the stability of the inner mounting plate 3 when installed outside the circular reinforcing rib 4. At the same time, the second reinforcing ribs 8 and the circular reinforcing rib 4 are fixed by welding to ensure that the inner mounting plate 3 maintains stability when positioned outside the circular reinforcing rib 4.

[0024] Please see Figure 2 The circular reinforcing rib 4 is circular, and the inner mounting plate 3 is arranged at equal intervals outside the circular reinforcing rib 4. The circular reinforcing rib 4 is fixed on the inner side of the inner mounting plate 3. The circular reinforcing rib 4 is circular, and the circle has stability. After the circular reinforcing rib 4 is installed inside the inner mounting plate 3, the circular reinforcing rib 4 can provide different placement pressures to the equipment, ensuring the overall compressive strength of the crossbeam body 1.

[0025] Please see Figure 3 Six sets of diagonal bracing plates are installed at equal intervals on the outside of the inner support 6. Support plates 7 are installed inside the diagonal bracing plates by spring steel. The inner support 6 and support plates 7 are installed inside the circular reinforcing rib 4. The spring steel installed inside the inner support 6 pushes the support plates 7 to move outward, ensuring that the support plates 7 are fitted tightly to the inside of the circular reinforcing rib 4. The inner support 6 and support plates 7 improve the support capacity inside the circular reinforcing rib 4, thereby improving the compressive strength of the equipment. The inner support 6 and support plates 7 can be disassembled and replaced from inside the circular reinforcing rib 4 during use, ensuring the structure is adjustable.

[0026] Working principle: In use, inner mounting plates 3 are sequentially and equally spaced and fitted onto the outside of the circular reinforcing ribs 4. The second reinforcing rib 8 is fitted onto the outside of the circular reinforcing ribs 4. Welding is used to fix the inner mounting plates 3 to the circular reinforcing ribs 4. The inner mounting plates 3 are fitted into the inside of the crossbeam body 1. The first reinforcing rib 2 limits the installation trajectory of the inner mounting plates 3 to ensure the stability of the inner mounting plates 3 during assembly. After the inner mounting plates 3 are installed and positioned, they are reinforced by welding. Meanwhile, the inner supports 6 and support plates 7 are installed inside the circular reinforcing ribs 4, which further reinforce the circular reinforcing ribs 4. The circular reinforcing ribs 4 are circular and can withstand pressure from different directions, continuously distributing the pressure to the inner mounting plates 3. As a result, during the installation and use of the crossbeam body 1, the overall compressive strength of the equipment can be improved, thereby increasing the service life of the equipment.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
