Description

Technical Field

[0001] This invention relates to the technical field of machining equipment, and more particularly to a machine tool beam and machine tool equipment. Background Technology

[0002] A machine tool is a piece of equipment used to manufacture machines and machinery. It typically consists of a bed and machining mechanisms mounted on the bed. The crossbeam is the core load-bearing and guiding component of the machine tool bed, and it is widely used in various CNC machine tools, machining centers, and other equipment. Its performance directly determines the machining accuracy, operational stability, and service life of the machine tool.

[0003] In related technologies, traditional machine tool crossbeams have obvious technical defects and shortcomings: traditional crossbeams mostly adopt solid structures or simple hollow structures, which either have insufficient torsional resistance, and the torque generated during operation can easily lead to local stress concentration in the crossbeam, which in turn causes deformation and other damage, affecting the machining accuracy of the machine tool; or increase the amount of material used, resulting in excessive weight of the crossbeam, which increases the overall load of the machine tool, increases energy consumption, and is not convenient for handling and installation, making it difficult to meet the use requirements of modern machine tools for high precision, lightweight, and flexible adaptation. Summary of the Invention

[0004] The purpose of this invention is to provide a machine tool beam and machine tool equipment to solve the problems of insufficient torsional resistance, high load energy consumption due to heavy weight, and inconvenience in handling and installation.

[0005] According to one aspect of the present invention, a machine tool crossbeam is provided, comprising:

[0006] A support plate having multiple honeycomb holes arranged side-by-side at intervals along the length of the support plate and extending through the thickness of the support plate.

[0007] A first horizontal plate and a second horizontal plate are respectively installed on opposite sides of the support plate in the width direction; and

[0008] Multiple honeycomb vertical columns are arranged side by side in a concave cavity formed by the support plate, the first horizontal plate and the second horizontal plate, and the honeycomb vertical columns abut against the first horizontal plate and the second horizontal plate.

[0009] In one embodiment, the support plate, together with the first horizontal plate and the second horizontal plate, forms a first concave cavity and a second concave cavity. The first concave cavity and the second concave cavity are arranged along the thickness direction of the support plate, and a plurality of honeycomb vertical columns are arranged side by side in both the first concave cavity and the second concave cavity.

[0010] In one embodiment, a first groove is recessed on the surface of the first horizontal plate away from the second horizontal plate, and a first limiting plate is slidably installed in the first groove.

[0011] And / or, a second groove is recessed on the surface of the second horizontal plate away from the first horizontal plate, and a second limiting plate is slidably installed in the second groove.

[0012] In one embodiment, a first limiting block is installed on the side of the first limiting plate facing the opening of the first slide groove; and / or, a second limiting block is installed on the side of the second limiting plate facing the opening of the second slide groove.

[0013] In one embodiment, the support plate has a first end and a second end that are spaced apart from each other along its length, the first end being provided with a snap-fit ​​assembly and the second end being provided with a latching assembly, wherein the snap-fit ​​assembly on one of the machine tool crossbeams can snap into the latching assembly on an adjacent machine tool crossbeam.

[0014] In one embodiment, the first end is provided with a rail groove, and the snap-fit ​​assembly includes an elastic element, a connecting plate and a snap-fit ​​block. One end of the elastic element is connected to the bottom wall of the rail groove, and the other end of the elastic element is fixed to the connecting plate. The snap-fit ​​block is installed on the side of the connecting plate away from the elastic element, and the snap-fit ​​block and the connecting plate can slide telescopically within the rail groove.

[0015] The clamping assembly includes an extension plate and a clamping body. The clamping body is disposed on the extension plate. When two adjacent machine tool crossbeams are spliced ​​together, the clamping block is engaged and fixed with the clamping body.

[0016] In one embodiment, the first end has a receiving groove, which is connected to the rail groove and is used to receive the card holder body.

[0017] In one embodiment, the first end is recessed to form a guide hole, and the second end is protruding to form a guide post. When two adjacent machine tool beams are spliced ​​together, the guide post is inserted into the guide hole.

[0018] In one embodiment, the machine tool crossbeam further includes a threaded component, and a first connecting seat and a second connecting seat are protruding from the outer side of the first cross plate and / or the second cross plate, the first connecting seat being arranged near the first end and the second connecting seat being arranged near the second end;

[0019] The first connecting seat has a through hole, and the second connecting seat has a threaded hole. The threaded component passes through the through hole and is screwed into the threaded hole.

[0020] According to another aspect of the present invention, a machine tool device is provided, which includes a machine tool beam as described above.

[0021] Implementing the embodiments of the present invention will have the following beneficial effects:

[0022] In this design, the machine tool crossbeam is assembled and integrated with a support plate, a first cross plate, a second cross plate, and honeycomb vertical columns. This improves the structural compactness and integration of the crossbeam, optimizing the combination of components and enhancing its structural mechanical properties. Specifically, multiple honeycomb holes are machined into the support plate and arranged side-by-side along the length of the support plate. The mechanical properties of the honeycomb structure enable core torsional resistance. The biomimetic honeycomb design effectively disperses the torque experienced by the crossbeam during machine operation, significantly reducing local stress concentration and preventing damage such as cracks and deformation caused by stress concentration. This significantly improves the overall torsional resistance of the crossbeam, ensuring long-term stable operation of the machine tool. Simultaneously, while ensuring torsional strength meets usage requirements, the honeycomb holes effectively reduce the material usage of the crossbeam, achieving lightweight design. This not only reduces the crossbeam's own weight but also reduces the overall load on the machine tool, lowering energy consumption and facilitating the handling and installation of the crossbeam. Furthermore, the first and second horizontal plates on both sides of the support plate provide reliable lateral support, effectively improving the structural strength and stability of the support plate and preventing lateral deformation when the support plate is subjected to torque. Finally, the multiple honeycomb vertical columns installed in the cavity further support and reinforce the first and second horizontal plates. The high strength and deformation resistance of the honeycomb vertical columns significantly enhance the torsional resistance of the machine tool beam. Attached Figure Description

Preferred embodiments of the invention are shown in the drawings. However, the invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a thorough and complete understanding of the disclosure of the invention.

When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the specification of this invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0033] Please refer to Figures 1-3 The machine tool crossbeam 100 described in one embodiment includes a support plate 10, a first cross plate 20, a second cross plate 30, and a plurality of honeycomb vertical columns 40.

[0034] Please see Figure 2 and Figure 4The support plate 10 has multiple honeycomb holes 11, which are arranged side by side at intervals along the length of the support plate 10 and penetrate through the thickness of the support plate 10. The first horizontal plate 20 and the second horizontal plate 30 are respectively installed on opposite sides of the width of the support plate 10. Multiple honeycomb vertical columns 40 are arranged side by side in the cavity formed by the support plate 10, the first horizontal plate 20 and the second horizontal plate 30, and the honeycomb vertical columns 40 abut against the first horizontal plate 20 and the second horizontal plate 30.

[0035] For example, the support plate 10, the first horizontal plate 20 and the second horizontal plate 30 are all rectangular metal plates, and the three can be integrally formed or detachable and assembled (such as through a snap-fit ​​structure, screw connection structure, etc.). The choice can be made as needed, and no specific limitation is made here.

[0036] Implementing the embodiments of the present invention will have the following beneficial effects:

[0037] In this solution, the machine tool crossbeam 100 is assembled and integrated with the support plate 10, the first cross plate 20, the second cross plate 30 and the honeycomb vertical column 40, which improves the structural compactness and integration of the machine tool crossbeam 100, realizes the optimized combination between the components, and thus improves the structural mechanical performance of the machine tool crossbeam 100. Specifically, by machining multiple honeycomb holes 11 on the support plate 10 and arranging the multiple honeycomb holes 11 side by side and spaced along the length of the support plate 10, the core anti-torsional function can be realized by utilizing the mechanical properties of the honeycomb structure. The biomimetic honeycomb structure design can effectively disperse the torque on the machine tool crossbeam 100 during machine operation, greatly reduce the phenomenon of local stress concentration, avoid damage such as cracks and deformation of the machine tool crossbeam 100 due to stress concentration, significantly improve the overall anti-torsional performance of the machine tool crossbeam 100, and ensure the long-term stable operation of the machine tool. Meanwhile, the honeycomb holes 11 effectively reduce the material usage of the machine tool crossbeam 100 while ensuring that the torsional strength meets the usage requirements, achieving a lightweight design. This not only reduces the weight of the machine tool crossbeam 100 itself but also reduces the overall load on the machine tool, lowers energy consumption, and facilitates the handling and installation of the machine tool crossbeam 100. In addition, the first horizontal plate 20 and the second horizontal plate 30 on both sides of the support plate 10 provide reliable lateral support, effectively improving the structural strength and stability of the support plate 10 and preventing lateral deformation when the support plate 10 is subjected to torque. Finally, the multiple honeycomb vertical columns 40 installed in the cavity further support and reinforce the first horizontal plate 20 and the second horizontal plate 30. The high strength and deformation resistance of the honeycomb vertical columns 40 significantly enhance the torsional performance of the machine tool crossbeam 100.

[0038] It should be noted that the honeycomb column 40 in this application specifically refers to a hollow column structure with a honeycomb structure in cross-section.

[0039] Please see Figure 1 and Figure 2 In one embodiment, the support plate 10, together with the first horizontal plate 20 and the second horizontal plate 30, forms a first concave cavity 50 and a second concave cavity 50a. The first concave cavity 50 and the second concave cavity 50a are arranged along the thickness direction of the support plate 10. Multiple honeycomb vertical columns 40 are arranged side-by-side within both the first concave cavity 50 and the second concave cavity 50a. Thus, by simultaneously forming the first concave cavity 50 and the second concave cavity 50a on opposite sides of the support plate 10 in the thickness direction, and simultaneously installing multiple honeycomb vertical columns 40 arranged side-by-side within the first concave cavity 50 and the second concave cavity 50a, the structural strength of opposite sides of the support plate 10 can be simultaneously enhanced, thereby improving the bending and deformation resistance of the machine tool beam 100.

[0040] Please see Figure 1 and Figure 2 Furthermore, in one embodiment, a first groove 21 is recessed on the surface of the first horizontal plate 20 away from the second horizontal plate 30, and a first limiting plate 22 is slidably installed in the first groove 21; and / or, a second groove 31 is recessed on the surface of the second horizontal plate 30 away from the first horizontal plate 20, and a second limiting plate 32 is slidably installed in the second groove 31.

[0041] For example, in this application, the first slide groove 21 and the second slide groove 31 coexist, that is, the first limiting plate 22 in the first slide groove 21 and the second limiting plate 32 in the second slide groove 31 coexist. When two adjacent machine tool crossbeams 100 are spliced ​​at their ends along the length direction, the first limiting plate 22 and the second limiting plate 32 can be slid to the splicing joint. By means of the engagement between the first limiting plate 22 and the second limiting plate 32 and the groove wall, the splicing strength of the two adjacent machine tool crossbeams 100 can be improved, and the bending resistance of the splicing joint can be enhanced. In addition, the first limiting plate 22 and the second limiting plate 32 also have the function of calibration and correction to ensure the flatness of the two adjacent machine tool crossbeams 100 after splicing.

[0042] Furthermore, in one embodiment, a first limiting block 23 is installed on the side of the first limiting plate 22 facing the opening of the first slide groove 21; and / or, a second limiting block 33 is installed on the side of the second limiting plate 32 facing the opening of the second slide groove 31.

[0043] By stacking the first limiting block 23 and the second limiting block 33 on the first limiting plate 22 and the second limiting plate 32 respectively, the thickness of the first limiting plate 22 and the second limiting plate 32 is increased, thereby improving the structural strength of both and giving the first limiting plate 22 and the second limiting plate 32 higher resistance to bending deformation.

[0044] It is necessary to explain that the first slide groove 21 and the second slide groove 31 in this solution are not simply U-shaped groove structures. Instead, based on the U-shaped groove structure, anti-detachment strip protrusions are further provided on the side walls of the two grooves near the groove opening. Both anti-detachment strip protrusions extend towards the groove cavity, thereby forming a locking and limiting connection with the first limiting plate 22 and the second limiting plate 32 (or it can also be a locking and limiting connection with the first limiting block 23 and the second limiting block 33), which prevents the first limiting plate 22 and the second limiting plate 32 from detaching from their respective installed first slide groove 21 and second slide groove 31.

[0045] Furthermore, in order to ensure convenient connection and fixation when two adjacent machine tool crossbeams 100 are spliced, and to ensure the splicing is firm, in one embodiment, the support plate 10 has a first end and a second end that are spaced apart from each other along its length. The first end is provided with a snap-fit ​​component 60 and the second end is provided with a retainer component 70. The snap-fit ​​component 60 on one machine tool crossbeam 100 can snap into the retainer component 70 on the adjacent machine tool crossbeam 100.

[0046] Please see Figure 4 Specifically, in one embodiment, the first end is provided with a rail groove 60a, and the snap-fit ​​assembly 60 includes an elastic member 61, a connecting plate 62 and a snap-fit ​​block 63. One end of the elastic member 61 is connected to the bottom wall of the rail groove 60a, and the other end of the elastic member 61 is fixed to the connecting plate 62. The snap-fit ​​block 63 is installed on the side of the connecting plate 62 away from the elastic member 61. The snap-fit ​​block 63 and the connecting plate 62 can slide telescopically within the rail groove 60a.

[0047] The clamping assembly 70 includes an extension plate 71 and a clamping body 72. The clamping body 72 is disposed on the extension plate 71. When two adjacent machine tool crossbeams 100 are spliced, the clamping block 63 is clamped and fixed to the clamping body 72.

[0048] When two adjacent machine tool crossbeams 100 are spliced, the snap-fit ​​assembly 60 of one machine tool crossbeam 100 is aligned and gradually moved closer to the snap-fit ​​assembly 70 of the other machine tool crossbeam 100, so that the snap-fit ​​body 72 contacts and pushes the snap-fit ​​block 63 to retract. The snap-fit ​​block 63 drives the connecting plate 62 to compress the elastic element 61. After the snap-fit ​​body 72 passes the snap-fit ​​block 63, under the push of the reset elastic force of the elastic element 61, the snap-fit ​​block 63 will automatically snap-fit ​​and fix with the snap-fit ​​body 72, so as to realize the snap-fit ​​and fixation of the two adjacent machine tool crossbeams 100. The snap-fit ​​assembly 60 and the snap-fit ​​assembly 70 have a high degree of automation and good connection reliability.

[0049] As is easily understood, the rail groove 60a is used to guide and limit the telescopic sliding connecting plate 62 and the locking block 63, while ensuring the rigidity and stability of the locking block 63 when it is engaged with the locking body 72.

[0050] The elastic element 61 can be a component or structure with elasticity, such as a spring or sheet.

[0051] As is easily understood, the card holder body 72 is provided with a card hole facing the card block 63. In order to facilitate the card block 63 to quickly and effectively engage in the card hole, the card block 63 is designed with a trapezoidal structure or a structure with rounded corners or other guiding functions to guide the card block 63 to engage in the card hole more smoothly. In particular, even if there is an installation alignment error, it can ensure that the card block 63 is accurately engaged in the card hole, thereby improving the assembly reliability of the card connector assembly 60 and the card holder assembly 70.

[0052] Furthermore, in another embodiment, a receiving groove 64 is provided at the first end, which communicates with the track groove 60a. The receiving groove 64 is used to receive the card holder body 72. During assembly, the receiving groove 64 is used to receive the adjacent card holder body 72, so that the card holder body 72 can move into the telescopic movement path of the card block 63, so that the card block 63 can be engaged into the card hole of the card holder body 72.

[0053] In one embodiment, a guide hole 80a is recessed at the first end, and a guide post 80 is protruding at the second end. When two adjacent machine tool crossbeams 100 are spliced, the guide post 80 is inserted into the guide hole 80a. When two adjacent machine tool crossbeams 100 are spliced, the guide post 80 inserted into the guide hole 80a guides and corrects the splicing of the two machine tool crossbeams 100, ensuring reliable and accurate docking and assembly between the first slide groove 21, between the second slide groove 31, and between the snap-fit ​​assembly 60 and the snap-fit ​​assembly 70.

[0054] Furthermore, in another embodiment, the machine tool crossbeam 100 further includes a threaded component 90, and a first connecting seat 90a and a second connecting seat 90b are protruding from the outer side of the first cross plate 20 and / or the second cross plate 30, with the first connecting seat 90a arranged near the first end and the second connecting seat 90b arranged near the second end.

[0055] The first connecting seat 90a has a through hole, and the second connecting seat 90b has a threaded hole. The threaded component 90 passes through the through hole and is screwed into the threaded hole.

[0056] With this configuration, the threaded component 90 can be screwed into the threaded hole to lock and fix two adjacent machine tool crossbeams 100, thereby strengthening the splicing strength and stability of the two adjacent machine tool crossbeams 100, enhancing the bending deformation resistance of the multiple machine tool crossbeams 100 after splicing, improving the service life and reliability of the machine tool crossbeams 100, and making them suitable for more complex working environments.

[0057] Preferably, two adjacent machine tool crossbeams 100 are secured by four sets of threaded components 90 arranged in a rectangular structure on the outer periphery, a first connecting seat 90a and a second connecting seat 90b, thereby further improving the structural performance of the spliced ​​multiple machine tool crossbeams 100.

[0058] In addition, this solution also provides a machine tool device, which includes the machine tool beam 100 as described above. It is understood that this machine tool device can be one of the following: a CNC machine tool, a machining center, etc., whichever is required.

[0059] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.
