Description

Technical Field

[0001] The utility model relates to the field of engraving machine equipment, and more specifically, to a crossbeam of an engraving machine. Background Technique

[0002] Engraving, in terms of processing principle, is a combined drilling and milling process. Engraving machines have various data input modes and can handle them with ease according to needs. Computer engraving machines are divided into two categories: laser engraving machines and mechanical engraving machines, and both of these categories have high-power and low-power types. Since the application range of engraving machines is very wide, it is necessary to understand the most suitable application range of various engraving machines. Low-power engraving machines are only suitable for making double-sided boards, architectural models, small signs, three-dimensional handicrafts, etc. Engraving jade, metals, etc. requires a power of more than 1500W. High-power engraving machines can do what low-power engraving machines can do, and are most suitable for large-scale cutting, embossing, and engraving.

[0003] In the Chinese patent with the patent publication number CN213734361U, two X-axis linear guide rail assemblies are installed along the length direction on the front side of the crossbeam; a Z-axis linear guide rail assembly is arranged along the height direction of the X slide plate. Therefore, the gravity of the engraving head all acts on the two X-axis linear guide rails on the side wall of the crossbeam, making the stability of the chute and the guide rail poor during use, and there will be a certain amount of vibration between the two, making it easy for the engraving head to deviate during movement and affecting the processing effect. Content of the Utility Model

[0004] The main technical problem to be solved by the utility model is to provide a crossbeam of an engraving machine with reasonable structural design, convenient operation, which enables the engraving head to move smoothly and improves the engraving accuracy.

[0005] To solve the above technical problem, the utility model provides the following technical solutions:

[0006] A crossbeam of an engraving machine, including a crossbeam body, characterized in that: two X-axis linear guide rails are arranged at intervals along the length direction on the front side of the crossbeam body, and one X-axis linear guide rail is further arranged along the length direction on the top of the crossbeam. The three X-axis linear guide rails are distributed in a triangular pattern on the crossbeam body. The crossbeam body is a hollow rectangular parallelepiped metal body, and a plurality of obliquely arranged metal rib plates are arranged inside the crossbeam body, and two adjacent metal rib plates form a V shape.

[0007] The following is a further optimization of the above technical solution of the utility model:

[0008] Further optimization: A weight-reducing hole is opened at a position close to the center of the metal rib plate.

[0009] Further optimization: The weight-reducing hole is a circular hole.

[0010] Further optimization: A plurality of through holes are uniformly and penetratingly formed on one side wall of the cross beam body.

[0011] Further optimization: The through holes are long strip arc-shaped holes.

[0012] Further optimization: A plurality of cover plates are detachably connected to the outer side wall of the cross beam body, and the cover plates are adapted to and correspond to the through holes one by one.

[0013] Further optimization: The cover plates are fixedly connected to the outer side wall of the cross beam body by bolts.

[0014] In the present utility model, two X-axis linear guide rails are arranged at intervals along the length direction on the front side of the cross beam body, and another X-axis linear guide rail is arranged at the top, and this layout in a pin shape enables the gravity of the engraving head to be more evenly distributed on the cross beam body 1, thus effectively avoiding excessive concentration of gravity at a certain place, greatly reducing the risk of beam deformation or guide rail damage caused by excessive local pressure, and further being able to provide a more stable and reliable support for the smooth movement of the engraving head, ensuring that the engraving head will not shake, shift, etc. during the movement, which will affect the engraving accuracy, and guaranteeing the smooth movement and accuracy of the engraving head.

[0015] In the present utility model, the cross beam body adopts a hollow structure, which not only reduces weight without reducing strength, but also provides space for the internal diagonal metal ribs.

[0016] In the present utility model, the diagonally arranged metal ribs can effectively resist external forces from different directions, such as the impact force generated during the movement of the engraving head and the vibration external force that the engraving machine may receive during operation.

[0017] Adopting the above technical solutions, the present utility model has a reasonable structural design and convenient operation, enables the engraving head to move smoothly, and improves the engraving accuracy.

[0025] like Figures 1-4 As shown, a crossbeam of an engraving machine comprises a crossbeam body 1, two X-axis linear guide rails 2 are arranged at intervals on the front side of the crossbeam body 1 along its length direction, and an X-axis linear guide rail 2 is also arranged on the top of the crossbeam body 1 along its length direction. The three X-axis linear guide rails 2 are distributed in a herringbone shape on the crossbeam body 1. The crossbeam body 1 is a hollow rectangular metal body, and a plurality of obliquely arranged metal ribs 3 are arranged inside the crossbeam body 1, and two adjacent metal ribs 3 form a V shape.

[0026] With such a design, firstly, two X-axis linear guide rails 2 are arranged at intervals along the length direction on the front side of the beam body 1, and another X-axis linear guide rail 2 is arranged on the top. This layout in a triangular distribution allows the gravity of the engraving head to be more evenly dispersed on the beam body 1, thereby effectively avoiding excessive concentration of gravity at a certain point, greatly reducing the risk of deformation of the beam or damage to the guide rail due to excessive local pressure, and thus providing more stable and reliable support for the smooth movement of the engraving head, ensuring that the engraving head will not shake or deviate due to unstable support during movement, which affects the engraving accuracy, thereby ensuring the smooth movement and accuracy of the engraving head.

[0027] Secondly, the cross beam body 1 adopts a hollow structure, which not only reduces weight without reducing strength, but also provides space for the internal oblique metal ribs 3.

[0028] Thirdly, the obliquely arranged metal ribs 3 can effectively resist external forces from different directions, such as the impact force generated by the engraving head during movement, the vibration force that the engraving machine may be subjected to during operation, and the like.

[0029] Finally, the adjacent metal ribs 3 form a V-shape to form a stable frame structure, so that the crossbeam can maintain its own shape stability when subjected to a large external force and is not easily deformed, thereby ensuring that the accuracy of the engraving head moving on the guide rail is not affected by the deformation of the crossbeam, thereby ensuring the engraving quality.

[0030] The metal rib plate 3 is provided with a weight-reducing hole 4 near the center thereof.

[0031] With such a design, a weight-reducing hole 4 is provided in the center of the metal rib 3, and the weight is reduced appropriately while ensuring the strength, making the cross beam lighter.

[0032] The weight-reducing hole 4 is a circular hole.

[0033] With such a design, first of all, when the cross beam is subjected to an external force, the stress distribution around the circular hole is uniform, and the stress can be diffused in a circular form, evenly shared, avoiding stress concentration at the hole edge, reducing the risk of deformation and damage of the metal rib 3 or the cross beam, and ensuring the movement and engraving accuracy of the engraving head.

[0034] Secondly, during the manufacturing process, the circular hole is easier to be accurately machined. Modern machining technologies can accurately drill it, and in mass production, the machining process is easy to be standardized and normalized, which can improve efficiency, reduce costs, and ensure quality consistency.

[0035] Thirdly, while achieving weight reduction, it has little impact on the overall material strength of the metal rib 3 and the cross beam. Due to the characteristics of the circular geometry, the surrounding materials can better maintain the strength under the same weight reduction, ensuring that the cross beam can resist external forces, ensuring that the cross beam does not deform when the engraving head moves, and ensuring the engraving quality.

[0036] A plurality of through holes 5 are uniformly and penetratingly provided on one side wall of the cross beam body 1.

[0037] With such a design, first of all, when the cross beam is subjected to an external force, the through holes 5 can disperse the stress, relieve stress concentration, reduce the risk of deformation and damage, maintain the structural stability, and ensure the movement accuracy and engraving quality of the engraving head.

[0038] Secondly, without affecting the strength of the cross beam, the through holes 5 reduce the self-weight of the cross beam, which is beneficial to the movement and handling of the engraving machine, making the operation more convenient, and can reduce energy consumption.

[0039] The through hole 5 is a long strip arc-shaped hole.

[0040] With such a design, the long strip arc-shaped hole can more effectively disperse the stress under the action of an external force. The arc-shaped edge guides the stress to conduct along the arc path, avoiding concentration, which can reduce the risk of deformation and damage of the cross beam, maintain the structural stability, and ensure the movement accuracy and engraving quality of the engraving head.

[0041] A plurality of cover plates 6 are detachably connected to the outer side wall of the cross beam body 1, and the cover plates 6 are adapted to and correspond to the through holes 5 one by one.

[0042] With such a design, first of all, it can protect the through holes 5, prevent external objects from entering and damaging the internal components, ensure the integrity of the cross beam structure and the movement and accuracy of the engraving head are not affected; it can also block dust and debris from entering, avoid their influence on component heat dissipation, causing corrosion or wear, extend the service life of the components, and reduce the maintenance cost.

[0043] Secondly, the cover plate 6 can be removed, which is convenient for viewing, detecting, and maintaining the internal components of the crossbeam body 1, simplifies the process, saves time and energy, and improves the maintenance efficiency; it is also more convenient when replacing components, can reduce the equipment downtime, and enhance the maintainability and usability.

[0044] The cover plate 6 is fixedly connected to the outer side wall of the crossbeam body 1 by bolts.

[0045] With such a design, firstly, the bolt connection provides a strong fastening force, making the cover plate 6 fit tightly. When the engraving machine is running and is disturbed by vibrations, collisions, etc., it can effectively prevent the cover plate 6 from loosening, shifting, or falling off. For example, during high-speed and high-intensity engraving operations, it can ensure that the protection of the long strip holes and the internal structure, the movement and accuracy of the engraving head are not affected.

[0046] Secondly, the installation operation is simple. Place the cover plate 6 in the corresponding position to align the bolt holes, and then use a wrench to screw in the bolts and tighten them. No complex skills or special tools are required, and the operator can quickly complete it after simple training, saving time and labor costs.

[0047] Thirdly, it allows the cover plate 6 to be installed and disassembled multiple times. As long as the bolts and threaded holes are not severely damaged, it can be accurately reinstalled after each disassembly, restoring functions such as protection and dust prevention, which is beneficial for frequent maintenance, repair, or adjusting the state of the cover plate 6 according to different scenarios, and reducing the maintenance cost.

[0048] The crossbeam body 1 is also provided with a transmission device, a detection device, etc., which are all prior arts. Their structures, working principles, installation principles, etc. all constitute prior arts and are well-known to those of ordinary skill in the art, so they will not be elaborated here.

[0049] For those of ordinary skill in the art, according to the teachings of the present invention, without departing from the principles and spirit of the present invention, the changes, modifications, substitutions, and variations made to the embodiments still fall within the protection scope of the present invention.
