Description

Technical Field

[0001] This application relates to the field of laser processing equipment technology, and in particular to a crossbeam and processing equipment. Background Technology

[0002] The Y-axis of laser cutting equipment typically includes a crossbeam, which serves as a support for other drive structures. The crossbeam significantly impacts the efficiency and stability of laser cutting. On one hand, structural optimization or material selection is needed to ensure sufficient rigidity in the crossbeam to reduce deformation errors during high-speed movement. On the other hand, the weight of the crossbeam must be controlled within a reasonable range to avoid increasing the load on the drive system and slowing down the motion response due to excessive weight. In other words, the crossbeam design must achieve a balance between "rigidity" and "lightweight design."

[0003] In related technologies, aluminum profiles are used for crossbeams to achieve weight reduction. However, crossbeams made of aluminum profiles still suffer from insufficient rigidity and strength, causing them to fail to meet usage requirements. Utility Model Content

[0040] Reference Figure 1 According to a first aspect embodiment of this application, a crossbeam includes an outer frame 100, an inner frame 200, and a first reinforcing rib 300. The outer frame 100 has a receiving cavity 110 and includes a corner portion 120. The inner frame 200 is located within the receiving cavity 110. The first reinforcing rib 300 is located between the inner peripheral surface 150 of the outer frame 100 and the outer peripheral surface 210 of the inner frame 200. One end of the first reinforcing rib 300 is connected to the outer frame 100, and the other end of the first reinforcing rib 300 is connected to the inner frame 200. There are two or more first reinforcing ribs 300, and at least one end of the first reinforcing rib 300 is connected to the corner portion 120.

[0041] The crossbeam according to the embodiments of this application has at least the following beneficial effects: the corner 120 of the outer frame 100 is a stress concentration point. At least one first reinforcing rib 300 is connected to the corner 120, which can more effectively disperse the load and impact force borne by the outer frame 100, and allow the stress to be reasonably transferred to the inner frame 200 along the first reinforcing rib 300, thereby reducing the risk of local stress concentration in the outer frame 100, which is conducive to improving the strength of the crossbeam; in addition, at least one first reinforcing rib 300 is connected to the corner 120, which can effectively increase the moment of inertia of the cross section of the crossbeam, thereby increasing the stiffness of the crossbeam.

[0042] Reference Figure 1 In some embodiments of this application, the outer frame 100 has a rectangular cross-section and includes four corners 120. Four first reinforcing ribs 300 are provided, and one end of each of the four first reinforcing ribs 300 is connected to one of the four corners 120.

[0043] The above structure can eliminate weak points at the corners 120, and stress can be distributed in all directions. The four corners 120 of the rectangular outer frame 100 are all areas of stress concentration risk. The four first reinforcing ribs 300 are connected to the four corners 120 respectively, which can prevent a certain corner 120 from becoming a failure point due to lack of reinforcement. The stress at each corner 120 of the beam is uniform, and the strength consistency of the beam is better.

[0044] Furthermore, the beam features a symmetrical anti-deformation structure, enhancing its stiffness and stability. Specifically, the four primary stiffeners are symmetrically distributed (adjacent angles are symmetrical, and diagonally symmetrical), ensuring a more balanced distribution of the beam's moment of inertia in both the horizontal and vertical directions, thus avoiding the "unidirectional deformation" problem caused by uneven stiffness distribution. Regardless of the direction from which external forces act on the beam, it maintains a consistent resistance to deformation.

[0045] Reference Figure 1 In the improved embodiment described above, the inner frame 200 has a circular cross-section.

[0046] The inner frame 200 has a circular cross-section, which optimizes the stress distribution within the inner frame 200 and avoids secondary stress concentration. Specifically, the circular cross-section has no geometric abrupt changes (no sharp corners), and compared to square or polygonal inner frames 200, the circular inner frame 200 avoids stress concentration points. When the first reinforcing rib 300 transfers the stress from the outer frame 100 to the inner frame 200, the circular inner frame 200 can evenly distribute the stress along the circumference, rather than concentrating it at a specific location, thereby further improving the overall rationality of the stress distribution of the beam.

[0047] In addition, the processing of the circular inner frame 200 (such as extrusion molding and subsequent drilling) makes it easier to ensure dimensional accuracy, thereby simplifying the processing technology and reducing production difficulty.

[0048] Reference Figure 1 In the improved scheme of the above embodiment, the vertical plane passing through the center line of the outer frame 100 is defined as the first plane 600, and the angle α between the first reinforcing rib 300 and the first plane 600 satisfies the relationship 45°≤α≤55°.

[0049] Angle α satisfies the relationship 45°≤α≤55°, maximizing force transmission efficiency and reducing force transmission loss. Specifically, when angle α is between 45° and 55°, the force transmission path of the first reinforcing rib 300 tends to be straight. When the outer frame 100 is subjected to vertical loads (such as gravity) or horizontal loads (such as inertial forces), the first reinforcing rib 300 at this angle can transmit the load to the inner frame 200 with minimal "force decomposition loss". When angle α is too large or too small, the load will generate an excessive lateral component force within the first reinforcing rib 300, causing local overload.

[0050] Specifically, the included angle α can be 45°, 50°, 55° or other values.

[0051] Reference Figure 1 In some embodiments of this application, the outer frame 100, the inner frame 200, and the first reinforcing rib 300 are connected as a whole.

[0052] By integrating the components, weak points in the connections can be eliminated, improving the overall structural integrity of the beam. Specifically, if welding or bolting is used, gaps may exist between the outer frame 100 and the first reinforcing rib 300, and between the inner frame 200 and the first reinforcing rib 300. These gaps are prone to failure due to poor contact or welding defects. Integrated molding effectively eliminates these gaps, reduces the risk of stress concentration at the joints, and thus improves the overall strength of the beam.

[0053] Specifically, the outer frame 100, the inner frame 200, and the first reinforcing rib 300 can be formed by extrusion molding or casting.

[0054] Reference Figure 2 In some embodiments of this application, the crossbeam further includes a second reinforcing rib 400, which is located between the inner peripheral surface 150 of the outer frame 100 and the outer peripheral surface 210 of the inner frame 200. The outer frame 100 includes a straight edge portion 160, one end of the second reinforcing rib 400 is connected to the straight edge portion 160, and the other end of the second reinforcing rib 400 is connected to the inner frame 200.

[0055] By incorporating the straight edge 160, its rigidity can be enhanced, preventing it from collapsing. Specifically, the straight edge 160 of the outer frame 100 is another easily deformable part besides the corner 120. When the beam is subjected to bending force, the straight edge 160 is prone to denting deformation due to the lack of support in the middle. The second reinforcing rib 400 connects the straight edge 160 to the inner frame 200, providing support for the straight edge 160 and improving its bending rigidity.

[0056] Reference Figure 1 In some embodiments of this application, the thickness d of the inner frame 200 satisfies the relationship 4≤d≤5, where the unit of thickness d is millimeters.

[0057] When the thickness d is in the range of 4 to 5 mm, the strength and lightweight requirements of the inner frame 200 can be balanced. Specifically, when the thickness d is in the range of 4 to 5 mm, it can ensure that the inner frame 200 has sufficient strength, while avoiding excessive weight due to excessive thickness, thereby avoiding excessive drive load on the processing equipment.

[0058] Specifically, the thickness d can be 4mm, 4.5mm, 5mm or other values.

[0059] Reference Figure 1In some embodiments of this application, the top surface of the outer frame 100 is provided with a first boss 130, which is used to mount a rack or guide rail.

[0060] Providing a first boss 130 on the top surface of the outer frame 100 can optimize the installation structure and improve assembly accuracy. Specifically, the first boss 130 can serve as a positioning reference for the rack or guide rail. Compared to direct installation on the top surface of the outer frame 100, the first boss 130 can limit the horizontal and vertical displacement of the rack or guide rail, reduce positioning errors during installation, and indirectly improve the motion accuracy of the processing equipment.

[0061] Reference Figure 1 In some embodiments of this application, the outer frame 100 has a second boss 140 on its side, which is used to mount a rack or guide rail.

[0062] By providing a second boss 140 on the side of the outer frame 100, the installation dimensions can be expanded to meet the needs of more scenarios. The second boss 140 can meet the installation requirements of racks or guide rails on the side. Compared with only providing a first boss 130 on the top surface of the outer frame 100, adding a second boss 140 on the side of the outer frame 100 can expand the functional adaptability of the crossbeam, and thus be used in more types of processing equipment (such as vertical or horizontal processing machines).

[0063] Reference Figure 3 According to a second aspect of the present application, the processing equipment includes a crossbeam and a processing device 500, the processing device 500 being used to process a workpiece, and the processing device 500 being mounted on the crossbeam.

[0064] The processing equipment according to the embodiments of this application has at least the following beneficial effects: by using the above-mentioned crossbeam, the rigidity and strength of the crossbeam are improved, thereby improving the processing accuracy and processing efficiency of the processing equipment.

[0065] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application. Furthermore, unless otherwise specified, the embodiments and features described in the embodiments of this application can be combined with each other.
