Description

Technical Field

[0001] This utility model relates to the field of machine tool parts technology, specifically to a crossbeam assembly and a processing platform. Background Art

[0002] Machine tools typically consist of components such as the bed, column, beam, worktable, and spindle. The machine tool performs machining operations on the workpiece through the spindle to achieve the required shape and dimensional accuracy. Its core function lies in the precise control of the movement trajectory and speed of each component through a control system.

[0003] Traditional machine tool crossbeam assemblies typically consist of only one main beam. This design, after prolonged, high-intensity spindle operation, leads to concentrated stress and a lack of effective support and reinforcement, making the crossbeam prone to bending and deformation. This bending not only affects the machine tool's machining accuracy, causing increased workpiece dimensional deviations, but also reduces the machine tool's overall stability and lifespan, thereby increasing equipment maintenance costs and downtime. Utility Model Content

[0004] This utility model provides a crossbeam assembly and processing platform, which can solve the problem that traditional machine tool crossbeams are prone to bending after long-term operation.

[0005] According to the present invention, a crossbeam assembly includes: a crossbeam body, the crossbeam body comprising an upper hollow square tube and a lower hollow square tube; and a reinforcing member for connecting the upper hollow square tube and the lower hollow square tube is provided on the side wall of the crossbeam body.

[0006] By using the upper and lower hollow square tubes in this invention, the weight of the crossbeam is reduced while maintaining sufficient strength and rigidity.

[0007] By incorporating reinforcing components in this invention, the bending resistance of the crossbeam is enhanced, preventing bending deformation of the crossbeam after prolonged high-intensity operation along the machine tool spindle, thereby improving the machining accuracy and overall stability of the machine tool.

[0008] In this utility model, the reinforcing member includes a first reinforcing plate in the shape of an arch. The top of the first reinforcing plate is welded to the top of the side wall of the upper hollow square tube, and the bottom two ends of the first reinforcing plate are welded to the bottom of the side wall of the lower hollow square tube.

[0009] The arched design in this invention allows the first reinforcing plate to better distribute stress under pressure, enhancing the load-bearing capacity of the beam. The welded connection ensures a strong bond between the reinforcing member and the beam body, improving the stability of the beam body.

[0010] In this utility model, the first arched plate is also provided with a plurality of connecting plates that are spaced apart along the length direction of the lower hollow square tube and perpendicular to the length direction of the lower hollow square tube. The upper end of the connecting plate is welded to the first arched plate.

[0011] By incorporating connecting plates in this invention, the connecting plates are welded simultaneously with the first reinforcing plate, ensuring a strong bond between them. This further enhances the connection strength between the first reinforcing plate and the lower hollow square tube, improving the torsional resistance of the crossbeam. The spaced connecting plates result in a more uniform stress distribution and reduce stress concentration.

[0012] In this utility model, the main body of the crossbeam also includes a base plate seat disposed at both ends of the bottom of the lower hollow square tube, and connecting holes are provided circumferentially at intervals along the edge of the base plate seat.

[0013] The base plate of this invention provides a stable support surface for the crossbeam body, ensuring its secure installation on the machine tool. The connection holes facilitate the connection and fixation of the crossbeam to other components (such as columns, worktables, etc.).

[0014] In this utility model, a T-shaped plate is provided at the top of the upper hollow square tube along the length direction of the upper hollow square tube.

[0015] The T-shaped plate in this invention enhances the strength and rigidity of the upper hollow square tube, preventing deformation caused by insufficient wall thickness. Simultaneously, the T-shaped plate serves as the mounting reference surface for the linear track, allowing for installation and adjustment during track setup. This improves the machining accuracy and stability of the machine tool.

[0016] In this utility model, an L-shaped plate is provided on the side of the lower hollow tube away from the reinforcing member along the length direction of the lower hollow square tube.

[0017] The L-shaped plate in this invention enhances the strength and rigidity of the upper hollow square tube, preventing deformation caused by insufficient wall thickness. Simultaneously, the L-shaped plate serves as the mounting reference surface for the linear track, allowing for installation and adjustment during track setup. This improves the machining accuracy and stability of the machine tool.

[0018] This utility model also provides a processing platform on which a beam assembly of this utility model is installed.

[0019] The reinforcing component of this utility model also includes a plurality of second reinforcing plates spaced apart along the length of the main body of the crossbeam. The second reinforcing plates are arched in shape and are fixedly connected to each other.

[0020] By incorporating multiple second reinforcing plates in this invention, the crossbeam's structural strength is enhanced along its length, improving its overall rigidity and load-bearing capacity. The fixed connection between adjacent reinforcing plates further strengthens the crossbeam's stability. Attached Figure Description

[0026] To further understand the content of this utility model, a detailed description of the utility model is provided in conjunction with the embodiments. It should be understood that the embodiments are merely illustrative and not limiting of the utility model.

[0027] Example 1

[0028] like Figure 1-4 As shown, this embodiment provides a crossbeam assembly, which includes: a crossbeam body 100, the crossbeam body 100 including an upper hollow square tube 110 and a lower hollow square tube 120; a reinforcing member 130 for connecting the upper hollow square tube 110 and the lower hollow square tube 120 is provided on the side wall of the crossbeam body 100.

[0029] By using the upper hollow square tube 110 and the lower hollow square tube 120 in this embodiment, the weight of the crossbeam is reduced while maintaining sufficient strength and rigidity.

[0030] The reinforcement 130 in this embodiment enhances the bending resistance of the crossbeam, preventing bending deformation of the crossbeam after the machine tool spindle has been working at high intensity along the crossbeam body 100 for a long time, thereby improving the machining accuracy and overall stability of the machine tool.

[0031] In this embodiment, the reinforcing member 130 includes an arched first reinforcing plate 131. The top of the first reinforcing plate 131 is welded to the top of the side wall of the upper hollow square tube 110, and the bottom two ends of the first reinforcing plate 131 are welded to the bottom of the side wall of the lower hollow square tube 120.

[0032] The arched design in this embodiment allows the first reinforcing plate 131 to better distribute stress when under pressure, enhancing the load-bearing capacity of the beam. The welded connection ensures a strong bond between the reinforcing member 130 and the beam body 100, improving the stability of the beam body 100.

[0033] In this embodiment, the first arched plate is also provided with a plurality of connecting plates 132 that are spaced apart along the length direction of the lower hollow square tube 120 and perpendicular to the length direction of the lower hollow square tube 120. The upper end of the connecting plate 132 is welded to the first arched plate.

[0034] With the connection plate 132 in this embodiment, when welding the first reinforcing plate 131, the connection plate 132 is welded simultaneously, ensuring a firm connection between them. This further enhances the connection strength between the first reinforcing plate 131 and the lower hollow square tube 120, and improves the torsional resistance of the beam. The spaced connection plates 132 make the stress distribution more uniform and reduce stress concentration.

[0035] In this embodiment, the main body 100 of the crossbeam also includes a base plate seat 140 disposed at both ends of the bottom of the lower hollow square tube 120, and connecting holes 141 are circumferentially spaced at the edge of the base plate seat 140.

[0036] In this embodiment, the base plate 140 provides a stable support surface for the crossbeam body 100, ensuring the secure installation of the crossbeam body 100 on the machine tool. The presence of the connecting hole 141 facilitates the connection and fixation of the crossbeam to other components (such as columns, worktables, etc.).

[0037] In this embodiment, a T-shaped plate 111 is provided at the top end of the upper hollow square tube 110 along the length direction of the upper hollow square tube 110.

[0038] The T-shaped plate 111 in this embodiment enhances the strength and rigidity of the upper hollow square tube 110, preventing deformation caused by insufficient wall thickness. Simultaneously, the T-shaped plate 111 serves as the mounting reference surface for the linear track, allowing for installation and adjustment based on it. This improves the machining accuracy and stability of the machine tool.

[0039] In this embodiment, an L-shaped plate 121 is provided on the side of the lower hollow tube away from the reinforcing member 130 along the length direction of the lower hollow square tube 120.

[0040] The L-shaped plate 121 in this embodiment enhances the strength and rigidity of the upper hollow square tube 110, preventing deformation caused by insufficient wall thickness. Simultaneously, the L-shaped plate 121 serves as the mounting reference surface for the linear track, allowing for installation and adjustment based on it. This improves the machining accuracy and stability of the machine tool.

[0041] This embodiment also provides a processing platform on which a beam assembly of this embodiment is installed.

[0042] The machining platform of this embodiment can be applied to various machine tool processing equipment such as bridge cutting machines, CNC cutting machines, and boring and milling machines.

[0043] Example 2

[0045] The reinforcing member 130 also includes a plurality of second reinforcing plates 133 spaced apart along the length of the main beam 100. The second reinforcing plates 133 are arched in shape and are fixedly connected to each other.

[0046] By setting multiple second reinforcing plates 133 in this embodiment, the crossbeam is strengthened in the length direction, which improves the overall stiffness and load-bearing capacity of the crossbeam. The fixed connection between adjacent second reinforcing plates 133 enhances the stability of the crossbeam.
