Description

Technical Field

[0001] This utility model belongs to the technical field of laser cutting equipment, specifically the welded crossbeam of a laser cutting machine. Background Technology

[0002] During the operation of a laser cutting machine, the crossbeam, as a key component that supports and guides the movement of the laser cutting head, has a crucial impact on the precision and quality of laser cutting. Currently, existing welded steel plate crossbeams in laser cutting machines have certain structural design flaws. Over prolonged use, due to vibrations generated by the laser cutting head and stresses produced during the cutting process, the crossbeam is prone to deformation, leading to decreased structural stability. This, in turn, affects the precision of laser cutting and reduces the machine's efficiency and processing quality. Furthermore, the existing welding process for crossbeams is also inadequate; the strength and reliability of the welded parts are insufficient to meet the demands of prolonged high-intensity operation, further impacting the overall structural stability of the crossbeam. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a welded steel plate crossbeam for laser cutting machines, so as to solve the problems of poor structural stability, easy deformation, and impact on laser cutting accuracy and work efficiency of existing laser cutting machine crossbeams.

[0004] The objective of this utility model can be achieved through the following technical solutions:

[0005] The welded steel plate crossbeam of the laser cutting machine includes:

[0006] The system comprises a base, a main crossbeam plate, and support components. The main crossbeam plate and the base are arranged in parallel. Multiple support components are evenly distributed between the base and the main crossbeam plate. Multiple intersecting support ribs are fixedly installed inside the main crossbeam plate. Two reinforcing support blocks are also provided between the base and the main crossbeam plate. The two reinforcing support blocks are located on both sides of the support components and are in the form of right-angled trapezoids. Two protective plates are fixedly installed on both sides of the main crossbeam plate by long screws.

[0007] Furthermore, the support assembly includes an upper connecting plate, a lower connecting plate, and a support column. The upper connecting plate is fixedly installed at the lower end of the main crossbeam plate, the lower connecting plate is fixedly installed at the upper end of the base, and the two ends of the support column are fixedly connected to the upper connecting plate and the lower connecting plate respectively. The support column is perpendicular to the base and the main crossbeam plate.

[0008] Furthermore, a shock-absorbing sleeve is fitted on the outer side of the support column. The shock-absorbing sleeve is made of rubber material, and the inner wall of the shock-absorbing sleeve is tightly fitted with the outer wall of the support column. The outer wall abuts against the inner side of the upper connecting plate and the lower connecting plate, respectively.

[0009] Furthermore, the main crossbeam plate has a cavity inside, and heat dissipation holes are provided at the upper end and both sides of the main crossbeam plate. Heat dissipation holes are also provided on both sides of the protective plate. The heat dissipation holes at the end of the protective plate that contacts the main crossbeam plate are all aligned.

[0010] Furthermore, guide rails for easy installation of laser cutting machines are fixedly installed on both sides of the upper end of the main crossbeam plate at the heat dissipation holes.

[0011] Furthermore, limit holes are provided at both ends of the upper end of the main crossbeam plate, and a limit post can be detachably installed at each of the limit holes.

[0012] The explanations of the nouns, conjunctions, or adjectives used in the above technical solutions are as follows:

[0013] Fixed connection: refers to a connection in which parts or components are fixed in place and there is no relative movement. It is divided into two types: detachable connection and non-detachable connection.

[0014] (1) Detachable connection: The components are fixed together using screws, splines, wedges, etc. This type of connection can be disassembled during maintenance without damaging the parts. However, the specifications of the connecting parts used must be correct (such as the length of the bolts, keys, wedges) and properly tightened.

[0015] (2) Non-removable connections: These mainly refer to welding, riveting, and tenon joints. Since disassembly requires forging, sawing, or oxyacetylene cutting for repair or replacement, the parts generally cannot be reused. At the same time, attention should be paid to process quality, technical inspection, and remedial measures (such as correction and polishing) during connection.

[0016] The beneficial effects of this utility model are:

[0017] 1. Through the cooperation of multiple evenly distributed support components, intersecting support ribs within the main crossbeam plate, and reinforced support blocks, the overall support strength and stability of the crossbeam are greatly improved, effectively reducing deformation and swaying of the crossbeam during operation, providing a stable working platform for laser cutting, and ensuring cutting accuracy.

[0018] 2. The cavity and multiple heat dissipation holes inside the main crossbeam plate, as well as the heat dissipation holes aligned with it on the protective plate, form an efficient heat dissipation channel. This channel can quickly dissipate the heat generated inside the crossbeam, reduce the crossbeam temperature, maintain its structural strength and performance stability, extend the crossbeam's service life, and also help ensure the normal operation of other components of the laser cutting equipment.

[0019] 3. The rubber shock-absorbing sleeves installed on the outside of the support column can effectively absorb the vibration generated during the operation of the crossbeam, reduce the impact of vibration on the laser cutting equipment, reduce cutting errors, improve cutting quality, and extend the service life of the crossbeam and related components.

Detailed Implementation

[0026] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] Laser cutting machine steel plate welded crossbeam, such as Figures 1-4 As shown, it includes:

[0028] The system comprises a base 1, a main crossbeam plate 2, and a support assembly 3. The main crossbeam plate 2 and the base 1 are arranged in parallel. Multiple support assemblies 3 are evenly distributed between the base 1 and the main crossbeam plate 2. Multiple intersecting support ribs 4 are fixedly installed inside the main crossbeam plate 2. Two reinforcing support blocks 5 are also provided between the base 1 and the main crossbeam plate 2. The two reinforcing support blocks 5 are located on both sides of the support assembly 3 and have a right-angled trapezoidal structure. Two protective plates 6 are fixedly installed on both sides of the main crossbeam plate 2 by long screws 7.

[0029] The laser cutting machine steel plate welding crossbeam provided by this utility model includes a base 1, a main crossbeam plate 2, and support components 3. The main crossbeam plate 2 and the base 1 are arranged in parallel. Multiple support components 3 are evenly distributed between the base 1 and the main crossbeam plate 2. Multiple intersecting support ribs 4 are fixedly installed inside the main crossbeam plate 2. By setting multiple evenly distributed support components 3 and intersecting support ribs 4 inside the main crossbeam plate 2, the overall support strength and stability of the crossbeam can be effectively enhanced, reducing deformation and shaking of the crossbeam during operation and ensuring the accuracy of laser cutting.

[0030] Two reinforcing support blocks 5 are also provided between the base 1 and the main crossbeam plate 2. The two reinforcing support blocks 5 are located on both sides of the support assembly 3, and the reinforcing support blocks 5 are in the form of right-angled trapezoids. The right-angled trapezoidal reinforcing support blocks 5 can further improve the stability of the crossbeam structure and enhance its load-bearing capacity without adding too much weight, so that the crossbeam can still maintain good structural performance when subjected to large loads.

[0031] Two protective plates 6 are fixedly installed on both sides of the main crossbeam plate 2 by long screws 7. The protective plates 6 not only protect the internal components of the crossbeam and prevent external debris from entering and affecting the normal operation of the crossbeam, but also improve the overall aesthetics of the crossbeam to a certain extent.

[0032] In a preferred embodiment of this invention, the support assembly 3 includes an upper connecting plate 8, a lower connecting plate 9, and a support column 10. The upper connecting plate 8 is fixedly installed at the lower end of the main crossbeam plate 2, and the lower connecting plate 9 is fixedly installed at the upper end of the base 1. The two ends of the support column 10 are fixedly connected to the upper connecting plate 8 and the lower connecting plate 9, respectively, and the support column 10 is perpendicular to the base 1 and the main crossbeam plate 2. This structural design makes the installation and disassembly of the support assembly 3 more convenient, while ensuring that the support column 10 can vertically and stably transmit the force between the main crossbeam plate 2 and the base 1, thereby improving the reliability of the support.

[0033] In a preferred embodiment of this invention, a shock-absorbing sleeve 11 is fitted onto the outer side of the support column 10. The shock-absorbing sleeve 11 is made of rubber material, and its inner wall is tightly fitted to the outer wall of the support column 10. The outer wall of the sleeve abuts against the inner sides of the upper connecting plate 8 and the lower connecting plate 9, respectively. The rubber shock-absorbing sleeve 11 effectively absorbs the vibrations generated during the operation of the crossbeam, reducing the impact of vibrations on the laser cutting equipment, lowering cutting errors, improving cutting quality, and extending the service life of the crossbeam and related components.

[0034] In a preferred embodiment of this utility model, the main crossbeam plate 2 has a cavity 12 inside, and heat dissipation holes 13 are provided at the upper end and both sides of the main crossbeam plate 2. Heat dissipation holes 13 are also provided on both sides of the protective plate 6. The heat dissipation holes 13 at the end of the protective plate 6 that contacts the main crossbeam plate 2 are all aligned. The cavity 12 inside the main crossbeam plate 2 and the multiple heat dissipation holes 13 form a good heat dissipation channel, which can accelerate the dissipation of heat inside the crossbeam, effectively reduce the crossbeam temperature, ensure that the crossbeam operates within a normal temperature range, and maintain its structural strength and performance stability.

[0035] In a preferred embodiment of this invention, guide rails 14 for easy installation of a laser cutting machine are fixedly installed on both sides of the upper end of the main crossbeam plate 2, located at the heat dissipation holes 13. The guide rails 14 provide guidance and support for the installation and movement of the laser cutting machine, enabling the laser cutting machine to operate stably on the crossbeam and ensuring the smooth progress of the cutting work.

[0036] In a preferred embodiment of this utility model, limit holes 15 are provided at both ends of the upper end of the main crossbeam plate 2, and a limit post 16 can be detachably installed at each of the limit holes 15. The limit post 16 can restrict the running position of the laser cutting machine on the crossbeam, prevent it from exceeding the predetermined range, and improve the safety and stability of the laser cutting equipment.

[0037] Working principle and usage process of this utility model:

[0038] In actual installation of the welded steel plate crossbeam of the laser cutting machine of this utility model, the base 1 is first fixed in the corresponding position of the laser cutting equipment to ensure that the base 1 is installed firmly and horizontally. Then, the lower connecting plate 9 of the support assembly 3 is fixedly installed on the upper end of the base 1 using bolts and other connecting parts. Next, the support column 10 is fixedly connected to the lower connecting plate 9 to ensure that the support column 10 is perpendicular to the base 1. Then, the shock-absorbing sleeve 11 is fitted on the outside of the support column 10, so that its inner wall fits tightly against the outer wall of the support column 10. Then, the main crossbeam plate 2 is placed on the support column 10, so that the upper end of the support column 10 is fixedly connected to the upper connecting plate 8 at the lower end of the main crossbeam plate 2 to ensure that the main crossbeam plate 2 is parallel to the base 1.

[0039] When installing the reinforcing support block 5, two right-angled trapezoidal reinforcing support blocks 5 are placed on both sides of the support component 3 and fixed between the base 1 and the main crossbeam plate 2 by welding or bolt connection, etc., to further enhance the stability of the crossbeam.

[0040] The protective plates 6 are fixedly installed on both sides of the main crossbeam plate 2 with long screws 7. During installation, make sure that the heat dissipation holes 13 on the contact end of the protective plate 6 are aligned one by one to ensure good heat dissipation.

[0041] At the upper end of the main crossbeam plate 2, guide rails 14 are fixedly installed on both sides of the heat dissipation holes 13 for mounting the laser cutting machine, enabling it to move stably on the guide rails 14. At the same time, limiting posts 16 are installed in the limiting holes 15 at both ends of the upper end of the main crossbeam plate 2. The position of the limiting posts 16 is adjusted according to actual needs to restrict the running position of the laser cutting machine.

[0042] During the operation of the laser cutting machine, the heat generated inside the crossbeam is dissipated through the heat dissipation holes 13 on the main crossbeam plate 2 and the protective plate 6. The shock-absorbing sleeve 11 can effectively absorb the vibration transmitted by the support column 10, ensuring the stable operation of the laser cutting machine and improving the cutting accuracy and quality.
