Description

Technical Field

[0001] This utility model belongs to the field of laser cutting machine inspection technology, and relates to a crossbeam verticality inspection workbench, particularly a laser cutting machine crossbeam verticality inspection workbench. Background Technology

[0002] A laser cutting machine is a device that uses the high power density energy generated by focusing a laser to achieve cutting. Laser cutting technology is mostly used for cutting large plates. Due to the large volume of the plates, a worktable is often set up. The worktable is equipped with a crossbeam for moving the laser cutting machine. In order to ensure the cutting accuracy of the laser cutting machine, the verticality of the crossbeam needs to be corrected before it is assembled with the worktable.

[0003] When the crossbeam of a laser cutting machine leaves the factory, its verticality needs to be inspected. However, the bumps during transportation can affect the verticality of the crossbeam. After assembly, in order to avoid the influence of the site and other factors, it needs to be inspected again. The traditional inspection method relies on hoisting the crossbeam to the machine bed, which requires repeated disassembly and assembly. The manual operation has large errors and low inspection efficiency. In addition, the marble platform of the inspection workbench cannot be dynamically adjusted, making it susceptible to the influence of site factors. Furthermore, it can only inspect the crossbeam of one specification of laser cutting machine, which has great limitations.

[0004] Therefore, we propose a laser cutting machine beam verticality inspection workbench. This workbench supports the inspection platform and allows for horizontal adjustment via several leveling shims, ensuring a stable and level position for subsequent accurate testing. The workbench connects directly to the cutting machine, avoiding repeated lifting and facilitating rapid testing. It also allows for dynamic leveling and calibration of the platform components, preventing interference and ensuring measurement accuracy. The position of the right-side guide rail assembly can be fine-tuned to improve compatibility with the laser cutting machine beam, reducing installation errors. It provides stable support and sliding guidance for the laser cutting machine beam and, through modular design, adapts to the inspection needs of various laser cutting machine beam specifications, making it widely applicable. Utility Model Content

[0005] The purpose of this utility model is to address the aforementioned problems in existing technologies by proposing a laser cutting machine beam verticality inspection workbench. The technical problem this utility model aims to solve is: how to achieve rapid and accurate verticality inspection of laser cutting machine beams of different specifications without hoisting through the workbench.

[0006] The objective of this utility model can be achieved through the following technical solutions: A laser cutting machine beam verticality inspection workbench includes an inspection workbench with a left guide rail assembly and a right guide rail assembly on the upper left and right sides respectively. A calibration platform assembly is provided on the upper inner side of the inspection workbench, and several leveling pad assemblies are provided on the lower end of the inspection workbench. During inspection, a laser cutting machine beam is provided between the left and right guide rail assemblies, and the laser cutting machine beam is located on the upper end of the calibration platform assembly.

[0007] The working principle of this utility model is as follows: When installing or maintaining the crossbeam of a laser cutting machine, the inspection workbench is hoisted so that the rear side of the inspection workbench is connected to the cutting machine to be tested. Then, the overall workbench is leveled by several leveling pad components at the lower end of the inspection workbench to ensure that the entire inspection workbench is in a stable and level state, providing a prerequisite for subsequent accurate testing. Then, the calibration platform components are dynamically leveled to avoid the calibration platform components being affected by the accuracy of the inspection workbench or the workbench surface of the cutting machine to be tested. Subsequently, the position of the right guide rail assembly is fine-tuned using the inspection workbench. The right and left guide rail assemblies correspond to the two guide rail positions of the cutting machine under test. Then, the laser cutting machine beam is slid onto the right and left guide rail assemblies, so that the right side of the laser cutting machine beam is slidably mounted on the right guide rail assembly, and the left side is slidably mounted on the left guide rail assembly. This achieves precise control over the installation position of the laser cutting machine beam. By cooperating with the right and left guide rail assemblies, the testing requirements of beams of different specifications can be met, achieving fast and accurate hoist-free installation and facilitating rapid testing. During inspection, the spatial orientation of the laser cutting machine beam is precisely positioned by combining the guiding effect of the right and left guide rail assemblies. Then, the staff uses measuring tools to measure the verticality of the laser cutting machine beam.

[0008] The inspection workbench includes a left platform and a right platform, which are arranged parallel to each other. The front end faces of the left and right platforms are flush. Two symmetrically arranged lifting lugs are provided on the upper left side of the left platform and the upper right side of the right platform. Both the left and right platforms have several storage tubes inside. A sliding groove is formed on the upper left and right sides of the right platform, within which a screw rotates. A slider is driven by the screw and is located inside the groove. The upper end face of the slider is flush with the upper end face of the right platform, and the right end of the screw... The right end of the right platform extends outwards, and a handwheel is fixed to the right end of the screw. A connecting beam and a mounting beam are provided between the left and right platforms. The mounting beam is located in front of the connecting beam. A reference mounting seat is located in the middle of the front side of the mounting beam. The front end of the reference mounting seat is flush with the front end of the right platform. Several fixing plates are provided at the lower ends of the reference mounting seat, the left platform, and the right platform. A connecting hinge plate is hinged to the upper front end of the reference mounting seat. A cover plate is hinged to the end of the connecting hinge plate. When not in operation, the end of the cover plate is in contact with the upper end of the mounting beam.

[0009] With the above structure, the inspection workbench can be hoisted when needed using the lifting lugs on the upper left side of the left platform and the upper right side of the right platform, facilitating its docking with the laser cutting machine to be tested. This allows the rear sides of the left and right platforms to connect with the cutting machine. Several storage tubes inside the left and right platforms can be used to store tools or items required for inspection. The reference mounting base at the middle of the front side of the mounting beam is used to install the calibration platform components. The connecting hinge plate at the upper front side of the reference mounting base and the cover plate at the end of the reference mounting base, when not in use, have the end of the cover plate in contact with the upper end of the mounting beam, providing protection and preventing debris from entering and affecting the inspection work. The cover plate can be opened for operation during use. The fixing plates at the lower ends of the left and right platforms and the lower end of the reference mounting base help to fix the entire inspection workbench, making it more stable and easier to adjust. The left and right platforms are parallel and their front end faces are flush, providing a stable foundation for subsequent inspection work. During the docking process, the handwheel is manually turned, which drives the screw to rotate. The screw then drives the slider to slide within the groove, which in turn drives the right guide rail assembly to slide. This allows for fine-tuning of the position of the right guide rail assembly to meet different inspection requirements, thereby ensuring the accuracy and reliability of the laser cutting machine's beam verticality inspection.

[0010] The right-side guide rail assembly includes a guide rail mounting plate, which is slidably mounted on the upper end of the right-side platform and is detachably connected to the slider. The upper end of the guide rail mounting plate has several fixing slots in the front-back direction. The distance between any two adjacent fixing slots is different. Each fixing slot is detachably equipped with a recessed part, and each recessed part is detachably equipped with a modular guide rail. During inspection, the right side of the laser cutting machine beam is slidably mounted on the corresponding modular guide rail.

[0011] Using the above structure, select the appropriate groove part 1 and module guide rail 1 according to the specifications of the laser cutting machine crossbeam, so as to match the right side of the laser cutting machine crossbeam, and install the groove part 1 in the fixing groove 1 that is adapted to the specifications of the laser cutting machine crossbeam, and then install the module guide rail 1 in the groove part 1 at the corresponding position. When adjusting the crossbeam of the laser cutting machine, the slider drives the guide rail mounting plate to move, and the guide rail mounting plate drives the groove part and the module guide rail to move. By adjusting the position of the module guide rail, the installation error of the laser cutting machine crossbeam is eliminated, so that the right side of the laser cutting machine crossbeam is matched with the module guide rail of the right guide rail assembly and installed stably. By setting different spacing between each fixed slot and its adjacent fixed slot, it can accommodate crossbeams of laser cutting machines of different specifications, thus having a wide range of applications.

[0012] The left guide rail assembly includes a guide rail mounting plate two, which is detachably mounted on the upper end of the left platform. The guide rail mounting plate two has two fixing grooves two, and each fixing groove two is detachably provided with a recessed part two. Each recessed part two is detachably provided with a modular guide rail two. The upper end surface of the modular guide rail two is flush with the upper end surface of the modular guide rail one. During inspection, the left side of the laser cutting machine beam is slidably mounted on the modular guide rail two at the corresponding position.

[0013] Using the above structure, select appropriate groove part two and module guide rail two according to the specifications of the laser cutting machine crossbeam to match the left side of the laser cutting machine crossbeam, and select appropriate groove part one and module guide rail one to meet the inspection requirements of laser cutting machine crossbeams of different specifications. During inspection, the left side of the laser cutting machine beam is slidably mounted on the corresponding modular guide rail two. Modular guide rail two provides sliding support and guidance for the left side of the laser cutting machine beam, allowing it to slide stably on the left guide rail assembly. Together with modular guide rail one, this completes the verticality inspection of the laser cutting machine beam. Guide rail mounting plate two provides a stable mounting base.

[0014] The calibration platform assembly includes an adjustment plate located inside the reference mounting base. Each of the four corners of the adjustment plate is screwed with a set of leveling screws. Each set of leveling screws consists of two fine-tuning screws. The ends of the fine-tuning screws pass through the adjustment plate and abut against the bottom of the reference mounting base. A marble reference platform is provided at the upper end of the adjustment plate.

[0015] Using the above structure, the height of the four corners of the adjustment plate can be changed by adjusting the fine-tuning screws at different positions. When the fine-tuning screw of a certain corner is rotated clockwise, the supporting effect of the end of the fine-tuning screw on the bottom of the reference mounting base is enhanced, and the position of that corner is raised; the opposite is true when rotated counterclockwise, and the position of the corner is lowered. When adjusting the adjustment plate, the marble reference platform will also adjust its level accordingly, thereby adjusting the level of the marble reference platform. After the adjustment is completed, the staff will use a level or other testing tools to check the level of the marble reference platform, providing an accurate reference plane for the verticality inspection of the laser cutting machine beam and avoiding inspection errors caused by the non-levelness of the inspection workbench.

[0016] The leveling pad assembly includes a pad base and leveling screws. The end of the leveling screw passes through the fixing plate at the corresponding position and is screwed into the inside of the pad base. Each pad base is screwed with a pad nut. The upper end of the pad nut is provided with a washer, and the upper end of the washer abuts against the lower end of the fixing plate at the corresponding position.

[0017] Using the above structure, by rotating the leveling screw, the threaded transmission action allows the shim base to move up and down relative to the fixed plate, thereby adjusting the height and levelness of the inspection workbench. Once the shim base is in position, tightening the shim nut ensures that the upper washer makes tight contact with the fixed plate, thus fixing the shim base in its current position and preventing displacement during subsequent use, ensuring the stability and leveling effect of the inspection workbench.

[0018] Compared with existing technologies, the laser cutting machine beam verticality inspection workbench has the following advantages: 1. The inspection workbench is supported by several leveling shims. During inspection, the workbench is leveled using these shims to ensure it is stable and level, providing a prerequisite for accurate subsequent testing. The workbench is then connected to the cutting machine to avoid repeated lifting and facilitate rapid testing.

[0019] 2. By dynamically leveling and calibrating the platform components, the accuracy of the calibration platform components is avoided from being affected by the precision of the inspection workbench or the workbench of the cutting machine under test, thus ensuring the accuracy of the measurement reference.

[0020] 3. Fine-tune the position of the right guide rail assembly by inspecting the workbench to improve the accuracy of the laser cutting machine beam installation position, ensure the matching between the right guide rail assembly and the laser cutting machine beam, and reduce installation errors.

[0021] 4. The right and left guide rail assemblies work together to provide stable support and sliding guidance for the laser cutting machine beam. Through modular design, it can adapt to the inspection needs of laser cutting machine beams of various specifications, and has a wide range of applications. Attached Figure Description

Detailed Implementation

[0030] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0031] like Figures 1-7 As shown, the laser cutting machine beam verticality inspection workbench includes an inspection workbench 1. The upper left and right sides of the inspection workbench 1 are respectively provided with a left guide rail assembly 6 and a right guide rail assembly 7. The upper inner side of the inspection workbench 1 is provided with a calibration platform assembly 4. The lower end of the inspection workbench 1 is provided with several leveling pad assemblies 2. During inspection, the laser cutting machine beam 3 is provided between the left guide rail assembly 6 and the right guide rail assembly 7. The laser cutting machine beam 3 is located on the upper end of the calibration platform assembly 4.

[0032] In this embodiment, when installing or maintaining the crossbeam 3 of the laser cutting machine, the inspection workbench 1 is hoisted so that the rear side of the inspection workbench 1 is connected to the cutting machine to be tested. Then, the overall workbench is horizontally adjusted by several leveling pad components 2 at the lower end of the inspection workbench 1 to ensure that the entire inspection workbench 1 is in a stable and horizontal state, providing a prerequisite for subsequent accurate testing. Then, the calibration platform component 4 is dynamically leveled to avoid the calibration platform component 4 being affected by the accuracy of the inspection workbench 1 or the workbench surface of the cutting machine to be tested. Subsequently, the position of the right guide rail assembly 7 is finely adjusted using the inspection workbench 1. The right guide rail assembly 7 and the left guide rail assembly 6 correspond to the two guide rail positions of the cutting machine under test. Then, the laser cutting machine crossbeam 3 is slid onto the right guide rail assembly 7 and the left guide rail assembly 6, so that the right side of the laser cutting machine crossbeam 3 is slidably installed on the right guide rail assembly 7, and the left side of the laser cutting machine crossbeam 3 is slidably installed on the left guide rail assembly 6. This achieves precise control over the installation position of the laser cutting machine crossbeam 3. The cooperation of the right guide rail assembly 7 and the left guide rail assembly 6 is used to adapt to the testing requirements of crossbeams of different specifications, achieving fast and accurate hoist-free installation and facilitating rapid testing. During inspection, the spatial orientation of the laser cutting machine crossbeam 3 is precisely positioned by combining the guiding effect of the right guide rail assembly 7 and the left guide rail assembly 6. Then, the staff uses measuring tools to measure the verticality of the laser cutting machine crossbeam 3.

[0033] The inspection workbench 1 includes a left platform 8 and a right platform 10, which are arranged in parallel. The front end face of the left platform 8 is flush with the front end face of the right platform 10. Two symmetrically arranged lifting lugs 11 are provided on the upper left side of the left platform 8 and the upper right side of the right platform 10. Several storage tubes 13 are provided inside both the left and right platforms 8 and 10. A sliding groove 5 is formed on the upper left and right sides of the right platform 10. A screw 19 is rotatably mounted within the sliding groove 5, and a slider 18 is driven on the screw 19. The slider 18 is located inside the sliding groove 5, and its upper end face is flush with the upper end face of the right platform 10. The right end of the screw 19 extends out to the right... A handwheel 20 is fixed to the right end of the screw 19 on the right end face of the side platform 10. A connecting beam 9 and a mounting beam 14 are provided between the left platform 8 and the right platform 10. The mounting beam 14 is located in front of the connecting beam 9. A reference mounting seat 15 is provided in the middle of the front side of the mounting beam 14. The front end face of the reference mounting seat 15 is flush with the front end face of the right platform 10. Several fixing plates 12 are provided at the lower ends of the reference mounting seat 15, the left platform 8 and the right platform 10. A connecting hinge plate 16 is hinged to the upper front end of the reference mounting seat 15. A cover plate 17 is hinged to the end of the connecting hinge plate 16. When not in operation, the end of the cover plate 17 is in contact with the upper end of the mounting beam 14.

[0034] In this embodiment, when needed, the inspection workbench 1 can be hoisted by the lifting lugs 11 on the upper left side of the left platform 8 and the upper right side of the right platform 10, facilitating its docking with the laser cutting machine to be tested. This allows the rear sides of the left platform 8 and the right platform 10 to dock with the cutting machine to be tested. Several storage tubes 13 inside the left platform 8 and the right platform 10 can be used to store some tools or items required for inspection. The reference mounting base 15 at the middle position of the front side of the mounting and fixing beam 14 is used to install the calibration platform assembly 4. The connecting hinge plate 16 and the end hinged cover plate 17 are hinged at the upper front side of the reference mounting base 15. When not in use, the end of the cover plate 17 contacts the upper end of the mounting and fixing beam 14, which serves as a protective function to prevent foreign objects from entering and affecting the inspection work. When in use, the cover plate 17 can be opened for operation. The fixing plate 12 at the lower end of the left platform 8 and the right platform 10, as well as at the lower end of the reference mounting base 15, can help fix the entire inspection workbench 1, making it more stable and easier to adjust. The left platform 8 and the right platform 10 are parallel and their front end faces are flush, providing a stable foundation for subsequent inspection work. During the docking process, the handwheel 20 is manually turned, which drives the screw 19 to rotate. The screw 19 drives the slider 18 to slide in the groove 5. The slider 18 drives the right guide rail assembly 7 to slide, thereby fine-tuning the position of the right guide rail assembly 7 to meet different inspection requirements and ensure the accuracy and reliability of the verticality inspection of the laser cutting machine beam.

[0035] The right guide rail assembly 7 includes a guide rail mounting plate 23, which is slidably mounted on the upper end of the right platform 10. The guide rail mounting plate 23 is detachably connected to the slider 18. The upper end of the guide rail mounting plate 23 has several fixing slots 24 in the front-back direction. The distance between any two adjacent fixing slots 24 is different. Each fixing slot 24 is detachably provided with a groove 22, and each groove 22 is detachably provided with a modular guide rail 21. During inspection, the right side of the laser cutting machine beam 3 is slidably mounted on the corresponding position of the modular guide rail 21.

[0036] In this embodiment, a suitable groove part 22 and a module guide rail 21 are selected according to the specifications of the laser cutting machine beam 3 to match the right side of the laser cutting machine beam 3. The groove part 22 is installed in the fixing groove 24 that adapts to the specifications of the laser cutting machine beam 3. Then, the module guide rail 21 is installed in the groove part 22 at the corresponding position. When adjusting the laser cutting machine crossbeam 3, the slider 18 drives the guide rail mounting plate 23 to move, and the guide rail mounting plate 23 drives the groove part 22 and the module guide rail 21 on it to move. By adjusting the position of the module guide rail 21, the installation error of the laser cutting machine crossbeam 3 is eliminated, so that the right side of the laser cutting machine crossbeam 3 is matched with the module guide rail 21 of the right guide rail assembly 7 and installed stably. By setting different spacings between fixed slot 24 and adjacent fixed slot 24, it can accommodate crossbeams 3 of laser cutting machines of different specifications, thus having a wide range of applications.

[0037] The left guide rail assembly 6 includes a guide rail mounting plate 25, which is detachably mounted on the upper end of the left platform 8. The guide rail mounting plate 25 has two fixing grooves 2, and each fixing groove 2 is detachably provided with a recessed part 26. The upper end of the recessed part 26 is detachably provided with a modular guide rail 2. The upper end surface of the modular guide rail 2 is flush with the upper end surface of the modular guide rail 21. During inspection, the left side of the laser cutting machine beam 3 is slidably mounted on the corresponding position of the modular guide rail 2.

[0038] In this embodiment, a suitable groove part 26 and a module guide rail 2 are selected according to the specifications of the laser cutting machine beam 3 to match the left side of the laser cutting machine beam 3. A suitable groove part 1 22 and a module guide rail 1 21 are also selected to meet the inspection requirements of laser cutting machine beams 3 of different specifications. During inspection, the left side of the laser cutting machine beam 3 is slidably mounted on the corresponding position of the modular guide rail 2. The modular guide rail 2 provides sliding support and guidance for the left side of the laser cutting machine beam 3, allowing the laser cutting machine beam 3 to slide stably on the left guide rail assembly 6. Together with the modular guide rail 1 21, it completes the verticality inspection of the laser cutting machine beam 3. The guide rail mounting plate 25 is used to provide a stable mounting base.

[0039] The calibration platform component 4 includes an adjustment plate 29, which is located inside the reference mounting base 15. Each of the four corners of the adjustment plate 29 is screwed with a set of leveling screws. Each set of leveling screws consists of two fine-tuning screws 27. The ends of the fine-tuning screws 27 pass through the adjustment plate 29 and abut against the bottom of the reference mounting base 15. A marble reference platform 28 is provided at the upper end of the adjustment plate 29.

[0040] In this embodiment, by adjusting the fine-tuning screws 27 at different positions, the height of the four corners of the adjustment plate 29 can be changed. When the fine-tuning screw 27 of a certain corner is rotated clockwise, the supporting effect of the end of the fine-tuning screw 27 at the bottom of the reference mounting base 15 is enhanced, and the position of that corner is raised; the opposite is true when rotated counterclockwise, and the position of the corner is lowered. When adjusting the adjustment plate 29, the marble reference platform 28 will also adjust its level accordingly, thereby adjusting the level of the marble reference platform 28. When the adjustment is completed, the staff will use a level or other testing tools to check the level of the marble reference platform 28, providing an accurate reference plane for the verticality inspection of the laser cutting machine beam 3, and avoiding inspection errors caused by the non-levelness of the inspection workbench 1.

[0041] The leveling pad assembly 2 includes a pad base 32 and a leveling screw 30. The end of the leveling screw 30 passes through the fixing plate 12 at the corresponding position and is screwed into the inside of the pad base 32. Each pad base 32 is screwed with a pad nut 31. The upper end of the pad nut 31 is provided with a washer, and the upper end of the washer abuts against the lower end of the fixing plate 12 at the corresponding position.

[0042] In this embodiment, by rotating the leveling screw 30, the threaded transmission action allows the shim base 32 to move up and down relative to the fixed plate 12, thereby adjusting the height and levelness of the inspection workbench 1. After the position of the shim base 32 is adjusted, the shim nut 31 can be tightened to make the upper end of the shim in close contact with the fixed plate 12, thereby fixing the shim base 32 in its current position and preventing it from shifting during subsequent use, ensuring the stability and leveling effect of the inspection workbench 1.

[0043] The working principle of this utility model is as follows: Select appropriate groove part 26 and module guide rail 2 according to the specifications of the laser cutting machine crossbeam 3, so as to match the left side of the laser cutting machine crossbeam 3, and select appropriate groove part 1 22 and module guide rail 1 21 to meet the inspection requirements of laser cutting machine crossbeam 3 of different specifications. When installing or maintaining the crossbeam 3 of the laser cutting machine, the inspection workbench 1 is hoisted so that its rear side is aligned with the cutting machine to be tested. This is achieved by using the lifting lugs 11 on the upper left side of the left platform 8 and the upper right side of the right platform 10 to hoist the inspection workbench 1, facilitating its alignment with the laser cutting machine. The rear sides of the left platform 8 and the right platform 10 are then aligned with the cutting machine. Subsequently, the overall workbench is leveled by using several leveling shim assemblies 2 at the lower end of the inspection workbench 1. This is achieved by rotating the leveling screws 30, which, through the transmission action of the threads, allows the shim bases 32 to move up and down relative to the fixed plate 12, thereby adjusting the height and levelness of the inspection workbench 1. After the position of the shim base 32 is adjusted, the shim nut 31 can be tightened to make the upper end of the shim in close contact with the fixing plate 12, thereby fixing the shim base 32 in the current position and ensuring that the entire inspection workbench 1 is in a stable and level state, providing a prerequisite for subsequent accurate testing. Next, the platform assembly 4 is dynamically leveled and calibrated, that is, by adjusting the fine-tuning screws 27 at different positions, the height of the four corners of the adjustment plate 29 can be changed. When the fine-tuning screw 27 of a certain corner is rotated clockwise, the end of the fine-tuning screw 27 supports the bottom of the reference mounting base 15. When the angle is raised, the position is lowered; when the angle is lowered, the position is raised. When the adjustment plate 29 is adjusted, the marble reference platform 28 will also adjust its level accordingly. When the adjustment is completed, the staff will use a level or other testing tools to check the level of the marble reference platform 28. This provides a precise reference plane for the verticality inspection of the laser cutting machine beam 3, avoids inspection errors caused by the non-levelness of the inspection workbench 1, and avoids interference from the accuracy of the calibration platform assembly 4 by the inspection workbench 1 or the workbench surface of the cutting machine to be tested. Subsequently, the position of the right guide rail assembly 7 is fine-tuned using the inspection workbench 1. This is achieved by manually rotating the handwheel 20, which drives the screw 19 to rotate. The screw 19 then drives the slider 18 to slide within the groove 5. The slider 18 moves the guide rail mounting plate 23, which in turn moves the grooved part 22 and the modular guide rail 21 on it. By adjusting the position of the modular guide rail 21, installation errors of the laser cutting machine beam 3 are eliminated, ensuring that the right side of the laser cutting machine beam 3 is properly fitted and stably installed with the modular guide rail 21 of the right guide rail assembly 7. The right guide rail assembly 7 and the left guide rail assembly 6 correspond to the two guide rail positions of the cutting machine under test. The laser cutting machine beam 3 is then slid onto the right guide rail assembly 7 and the left guide rail assembly 6, so that the right side of the laser cutting machine beam 3 is slidably mounted on the right guide rail assembly 7, and the left side is slidably mounted on the left guide rail assembly 6, thus achieving laser... The precise control of the installation position of the laser cutting machine crossbeam 3, through the cooperation of the right guide rail assembly 7 and the left guide rail assembly 6, adapts to the testing requirements of crossbeams of different specifications, achieving rapid, hoist-free installation and facilitating quick testing. During inspection, the guide effect of the right guide rail assembly 7 and the left guide rail assembly 6 is combined, meaning the left side of the laser cutting machine crossbeam 3 is slidably set on the corresponding position of the module guide rail 2. The module guide rail 2 provides sliding support and guidance for the left side of the laser cutting machine crossbeam 3, allowing the laser cutting machine crossbeam 3 to slide stably on the left guide rail assembly 6. In conjunction with the module guide rail 1 21, the spatial posture of the laser cutting machine crossbeam 3 is precisely positioned. Subsequently, the operator uses measuring tools to measure the verticality of the laser cutting machine crossbeam 3. When not in operation, the end of the cover plate 17 contacts the upper end of the mounting and fixing beam 14, providing protection and preventing debris from entering and affecting the inspection work. When in operation, the cover plate 17 can be opened for operation.

[0044] In summary, the inspection workbench 1 is supported by several leveling shim assemblies 2, and the inspection workbench 1 is leveled during inspection by several leveling shim assemblies 2 to ensure that the entire inspection workbench 1 is in a stable and level state, providing a prerequisite for subsequent accurate testing. The inspection workbench 1 is connected to the cutting machine to avoid repeated hoisting and facilitate rapid testing.
