Description

Technical Field

[0001] This application relates to the field of industrial laser installation and performance testing technology, and in particular to an industrial laser performance installation and testing method based on the deformation absorption principle. Background Technology

[0002] As precision machining equipment, the installation stability of industrial lasers is crucial to the output beam quality, processing accuracy, and equipment lifespan. In actual operating conditions, changes in ambient temperature can cause thermal expansion and contraction of the laser housing. If the installation structure lacks an effective deformation absorption design, stress concentration can easily occur inside the housing, leading to displacement of optical components, optical path misalignment, or even damage to mechanical parts.

[0003] Traditional industrial laser mounting methods often employ rigid support structures (such as direct bolt connection between the housing and mounting base). While these structures ensure mechanical strength, they cannot accommodate housing deformation caused by temperature changes, leading to performance degradation due to stress accumulation over long-term use. Existing technologies have attempted to absorb minor deformations using elastic gaskets or simple slotted structures, but these methods suffer from the following drawbacks: 1. Single-direction deformation absorption: It only addresses deformation in a single direction (such as lateral or longitudinal) and cannot cope with complex deformation of the casing in orthogonal directions; 2. Difficulty in coordinating structural stiffness and deformation capacity: The deformation of traditional elastic structures is difficult to control precisely. Excessive elasticity will lead to insufficient rigidity of the casing, while excessive rigidity will prevent effective stress absorption. 3. Crude installation and testing methods: The lack of quantitative testing methods for deformation-absorbing structures makes it impossible to dynamically adjust structural parameters according to actual working conditions, resulting in installation reliability relying on experience-based design and making it difficult to meet high-precision requirements.

[0004] Currently, no technical solution has been found to effectively absorb multi-directional deformation of the casing through orthogonally distributed support column slots and adjustable stiffness connecting rod structures, nor has a closed-loop testing method of "structural design - installation positioning - load simulation - parameter optimization" been established.

[0005] Therefore, a method is urgently needed to solve at least one of the above problems. Summary of the Invention

[0006] This application provides an industrial laser performance installation and testing method based on the deformation absorption principle. It aims to solve the problem that there is currently no technical solution that can achieve targeted absorption of multi-directional deformation of the housing through orthogonally distributed support column slots and adjustable stiffness connecting rod structure, nor has a closed-loop testing method of "structural design-installation positioning-load simulation-parameter optimization" been formed.

[0007] In a first aspect, embodiments of this application provide a method for installing and testing the performance of an industrial laser based on the principle of deformation absorption, including: A first support column and a second support column are installed at the bottom of the industrial laser housing; The first connecting rod is set below the first support column, and the second connecting rod is set below the second support column. The first connecting rod and the second connecting rod are rectangular plate structures with small slits in the width and a reduction in thickness in the middle area. The small slits on the first connecting rod and the second connecting rod are set at the connection ends with the first support column and the second support column. Position the mounting slot through holes on both sides of the bottom of the first support column, the mounting slot through holes on both sides of the bottom of the second support column, and the mounting slot through holes on both sides of the first connecting rod and the second connecting rod. A stress load simulating temperature change is applied to the installed laser housing to simulate the expansion or contraction of the housing when the ambient temperature changes; the deformation of the small cuts on the first and second connecting rods is detected to determine whether the deformation is within the design range; if the detected deformation exceeds the design range, the first and second connecting rods are replaced with different thinning thicknesses until the deformation is within the preset design range.

[0008] This invention utilizes orthogonally distributed support column slots and connecting rod slits to absorb thermal deformation of the housing in both the axial and vertical directions, preventing stress concentration from affecting internal components and improving the long-term stability of the laser. By replacing connecting rods with different thicknesses, the elastic stiffness of the structure can be flexibly adjusted to adapt to the deformation absorption requirements of lasers of different power and size, enhancing the versatility of the solution. Through simulated temperature load and deformation detection, quantitative evaluation and parameter optimization of the installation structure can be achieved, avoiding the blindness of traditional experience-based design and ensuring that installation reliability meets the requirements of high-precision operating conditions. The preset torque design of the fixed structure limits the rigid displacement of the housing while allowing for the absorption of temperature stress through elastic deformation, balancing installation stability and deformation adaptability.

[0018] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0019] As precision machining equipment, the installation stability of industrial lasers is crucial to the output beam quality, processing accuracy, and equipment lifespan. In actual operating conditions, changes in ambient temperature can cause thermal expansion and contraction of the laser housing. If the installation structure lacks an effective deformation absorption design, stress concentration can easily occur inside the housing, leading to displacement of optical components, optical path misalignment, or even damage to mechanical parts.

[0020] Traditional industrial laser mounting methods often employ rigid support structures (such as direct bolt connection between the housing and mounting base). While these structures ensure mechanical strength, they cannot accommodate housing deformation caused by temperature changes, leading to performance degradation due to stress accumulation over long-term use. Existing technologies have attempted to absorb minor deformations using elastic gaskets or simple slotted structures, but these methods suffer from the following drawbacks: 1. Single-direction deformation absorption: It only addresses deformation in a single direction (such as lateral or longitudinal) and cannot cope with complex deformation of the casing in orthogonal directions; 2.

[0021] Currently, no technical solution has been found to effectively absorb multi-directional deformation of the housing through orthogonally distributed support column slots and adjustable stiffness connecting rod structures, nor has a closed-loop testing method encompassing "structural design - installation positioning - load simulation - parameter optimization" been established. This invention, through innovative mechanical structure design and quantitative testing processes, solves the problems of incomplete deformation absorption and lack of basis for parameter adjustment in existing technologies, providing a completely new solution for the stable installation of high-precision industrial lasers.

[0022] Please refer to Figure 1 ,like Figure 1 The diagram shown is a schematic flowchart of an industrial laser performance installation and testing method based on the deformation absorption principle provided in an embodiment of this application. The method is used for installation and testing. Figures 2-4 The corresponding installation structure. This industrial laser performance installation and testing method based on the deformation absorption principle can be implemented using computer equipment, which can be deployed on a single server or server cluster. It can also be deployed on handheld terminals, laptops, wearable devices, or robots, etc.

[0023] Please refer to Figures 2-4 This application provides an industrial laser performance installation and testing structure based on the deformation absorption principle, obtained by the installation and testing method provided in any embodiment of this application. The provided installation and fixing structure includes a fixing screw 21, a first support column 1, a second support column 3, a first connecting rod 2, and a second connecting rod 4. Both the bottom sides of the first and second support columns have mounting slot through holes, and the top sides have mounting threaded blind holes. The first connecting rod is located below the first support column, with mounting slot through holes on both sides, and both ends are connected to the first support column via the fixing screw. The second connecting rod is located below the second support column, with mounting slot through holes on both sides, and both ends are connected to the second support column via the fixing screw.

[0024] Specifically, such as Figure 1 As shown, the industrial laser performance installation and testing method based on the deformation absorption principle includes steps S101 to S104, which are detailed below: Step S101. Install a first support column and a second support column at the bottom of the industrial laser housing.

[0025] Specifically, by fixing a first support column and a second support column at the bottom of the industrial laser housing, both of which are semi-cylindrical structures but with orthogonal groove directions, a guiding and absorbing structure for multi-directional deformation of the housing is formed.

[0026] The first support column is a semi-cylinder (with its diameter side against the bottom of the casing), with a groove cut along its diameter (i.e., perpendicular to the axis of the semi-cylinder) to absorb thermal expansion deformation along the axial direction (longitudinal direction) of the casing; the second support column is a semi-cylinder (with its semi-circular arc side against the bottom of the casing and its semi-circular plane facing outward), with a groove cut along its semi-circular plane (i.e., parallel to the axis of the semi-cylinder) to absorb thermal expansion deformation along the vertical axis (lateral direction) of the casing; the orthogonal layout forms independent deformation absorption channels in the X / Y axis directions by having the groove directions of the two support columns perpendicular to each other.

[0027] The semi-cylindrical support columns are machined using rigid materials such as aluminum alloy or cast iron. The groove width is 0.5-2mm (designed according to the laser size), and the depth penetrates 1 / 3-1 / 2 of the height of the semi-cylindrical column to ensure that a flexible deformation area is formed at the groove. The diameter surface (plane) of the first support column is in contact with the bottom of the housing, and the groove extends along the centerline direction (longitudinal) of the diameter surface. The semi-circular plane (plane) of the second support column faces outward, and the groove extends along the width direction (lateral) of the semi-circular plane.

[0028] Positioning and installation: Use positioning fixtures (such as templates with orthogonal grooves) to calibrate the direction of the support columns: The groove direction of the first support column is parallel to the axis of the housing (laser emission direction) (defined as the Y-axis direction); the groove direction of the second support column is perpendicular to the axis of the housing (defined as the X-axis direction), and the two form an orthogonal coordinate system; a threaded blind hole is opened at the top of the support column, which is aligned with the preset screw hole at the bottom of the housing, and is fastened with anti-loosening screws to ensure that the support column is rigidly connected to the housing, but the grooved area can deform freely.

[0029] Step S102. Place the first connecting rod under the first support column and the second connecting rod under the second support column. The first and second connecting rods are rectangular plate structures with small slits in width and a reduction in thickness in the middle area. The small slits on the first and second connecting rods are located at the connection ends with the first and second support columns.

[0030] Specifically, by connecting a flexible connecting rod below the support column and using a design that cuts at both ends and thins in the middle, an adjustable stiffness structure with "flexible hinges at both ends + elastic deformation in the middle" is formed, which matches the orthogonal deformation absorption direction of the support column.

[0031] The connecting rod structure is a rectangular plate (the length direction is consistent with the groove direction of the support column), with small slits (0.2-1mm wide) at both ends in the width direction, and the thickness in the middle area is reduced (the reduction is 1 / 4-1 / 2 of the original thickness), forming a weak area for elastic deformation; the first connecting rod connects to the first support column (corresponding to deformation in the Y-axis direction), and the second connecting rod connects to the second support column (corresponding to deformation in the X-axis direction), with the slit direction consistent with the groove direction of the support column.

[0032] The connecting rod is made of spring steel or titanium alloy to ensure elastic deformation capacity and fatigue strength. The slits are made at the connection points of the connecting rods near the support columns at both ends, and are cut along the width direction (perpendicular to the length direction) to form a "flexible hinge point" that allows for slight angular deflection. The thickness of the middle 1 / 3 area is reduced by milling or stamping to form an elastic beam structure. The thickness reduction is calculated based on the estimated deformation (e.g., Hooke's Law: deformation ΔL=FL / (EA), where E is the elastic modulus and A is the cross-sectional area).

[0033] The installation connection uses fixing screws to connect both ends of the connecting rod to the bottom of the support column: the bottom of the support column has a countersunk through hole (the countersunk hole is used to accommodate the screw head and prevent it from protruding), and the corresponding positions of both ends of the connecting rod have through holes; by ensuring that the cutting direction of the first connecting rod is consistent with the cutting direction of the first support column (Y-axis), and the cutting direction of the second connecting rod is consistent with the cutting direction of the second support column (X-axis), a directional transmission path is formed in which "the connecting rod in the Y-axis direction absorbs longitudinal deformation, and the connecting rod in the X-axis direction absorbs lateral deformation".

[0034] Step S103. Position the mounting slot through holes on both sides of the bottom of the first support column, the mounting slot through holes on both sides of the bottom of the second support column, and the mounting slot through holes on both sides of the first connecting rod and the second connecting rod.

[0035] Specifically, by performing three-dimensional positioning of the mounting holes of the support columns and connecting rods, the relative positional accuracy of each component is ensured. Finally, the fixed structure is connected to the external foundation to form a flexible connection system of "casing-support column-connecting rod-installation foundation".

[0036] The horizontal (X-axis) and vertical (Y-axis) spacing of the positioning target should conform to the design parameters (e.g., the spacing of the support columns should be set to 200-500mm according to the size of the housing). The through holes in the vertical direction (Z-axis) should be fully aligned to avoid installation stress deviation. The fixed structure should limit the rigid displacement of the housing (e.g., translation, flipping), but allow the support columns and connecting rods to absorb temperature stress through elastic deformation (not completely rigid fixation).

[0037] The three-dimensional positioning method uses a coordinate measuring machine (CMM) or laser tracker to collect the coordinates of each through hole and establish a local coordinate system at the bottom of the housing: the coordinates of the through holes at the bottom of the first support column are (X1,Y1,Z1) and (X1,Y2,Z1), and the coordinates of the through holes of the second support column are (X2,Y3,Z1) and (X2,Y4,Z1). The through holes of the connecting rods must deviate from the corresponding through holes of the support columns in the Z-axis direction by ≤0.05mm. Positioning pin holes are preset at the bottom of the housing and the mounting foundation. During installation, the positioning pins are first inserted to determine the reference, and then the positions of the through holes are calibrated.

[0038] For fixed connections, screws with a preset torque (such as M4-M8 stainless steel screws) are passed through the mounting slot through holes of the support column and connecting rod in sequence, and then screwed into the screw holes of the mounting base. The torque parameter is set according to the calculation of mechanics of materials. The torque must meet the requirement that "the screw preload is sufficient to limit the rigid displacement of the housing, but does not exceed the critical load for the elastic deformation of the connecting rod" (for example, the torque range is 8-15 N·m, optimized by finite element simulation), so that the system remains rigid under static conditions and allows elastic deformation under temperature load.

[0039] Step S104. Apply a stress load simulating temperature changes to the installed laser housing to simulate the expansion or contraction of the housing when the ambient temperature changes; detect the deformation of the small cuts on the first and second connecting rods to determine whether the deformation is within the design range; if the detected deformation exceeds the design range, replace the first and second connecting rods with different thinning thicknesses until the deformation is within the preset design range.

[0040] Specifically, by simulating temperature changes to apply stress loads, the deformation of the connecting rod cut is detected. By replacing connecting rods with different thinning thicknesses, the deformation absorption capacity is quantitatively optimized, forming a "test-feedback-correction" closed loop.

[0041] Load simulation simulates the expansion / contraction of the casing caused by changes in ambient temperature (e.g., from -20℃ to +60℃), causing the support column to drive the connecting rod to produce elastic deformation; deformation detection monitors the opening and closing displacement of the slit in real time to determine whether it exceeds the design threshold (e.g., ±0.3mm). If it exceeds the limit, the thickness of the connecting rod is replaced until the deformation meets the standard.

[0042] Temperature load application includes: Temperature control chamber method: The laser is placed in a programmable temperature control chamber and the temperature is cyclically changed according to a preset curve (e.g., heating / cooling by 5℃ every 10 minutes), while the surface temperature of the casing is monitored simultaneously (via thermocouples or infrared thermal imagers) to ensure that the temperature uniformity error is ≤±1℃; Local heating method: A combination of heating and cooling plates is attached to the surface of the casing, and a PID control algorithm is used to simulate gradient temperature changes, which is suitable for precise loading of local deformation-sensitive areas.

[0043] Deformation detection includes: Contact detection: Install miniature displacement sensors (such as LVDT linear displacement sensors) on both sides of the cut of the connecting rod, with an accuracy of 0.001mm, to collect the change in the width of the cut ΔW in real time (such as detecting the lateral displacement of the connecting rod in the X-axis direction and the longitudinal displacement in the Y-axis direction); Visual detection (optional): Take images of the cut through an industrial camera, use edge detection algorithms to calculate the opening and closing dimensions of the cut (such as using the OpenCV library to identify edge coordinate differences), and cross-check with the displacement sensor data.

[0044] The parameter optimization process establishes a connecting rod thickness-deformation mapping table: different thinning thicknesses (e.g., 2mm, 3mm, 4mm) are preset for connecting rods, corresponding to different elastic stiffnesses (the smaller the thickness, the lower the stiffness, and the larger the deformation); if the detected deformation ΔW > the design upper limit (e.g., 0.5mm), it indicates insufficient stiffness, and a connecting rod with a larger thickness is replaced; if ΔW < the design lower limit (e.g., 0.1mm), it indicates excessive stiffness, and a thinner connecting rod is replaced; the installation-loading-testing steps are repeated until ΔW falls within the design range (e.g., 0.2-0.4mm), forming the final adapted installation structure.

[0045] In some embodiments, by clearly defining the connection method and slit direction matching relationship between the connecting rod and the support column, a mechanical connection is achieved by fixing screws, ensuring that the slit direction is consistent with the groove direction of the support column, thus forming a directional deformation absorption path.

[0046] The first connecting rod has threaded holes or smooth holes at both ends corresponding to the through holes in the recessed grooves at the bottom of the first support column. M4-M6 fixing screws (such as stainless steel anti-loosening screws) are passed through these through holes and tightened, with the screw heads recessed into the grooves to prevent protrusions from affecting deformation. The second connecting rod is connected to the second support column in the same way. The slit direction is calibrated before installation using a tooling fixture (such as a positioning plate with angle scales): the small slits of the first connecting rod are along the length direction (consistent with the diameter groove direction of the first support column, i.e., the direction of the housing axis) to absorb longitudinal (Y-axis) deformation; the small slits of the second connecting rod are along the width direction (consistent with the semi-circular plane groove direction of the second support column, i.e., perpendicular to the housing axis) to absorb lateral (X-axis) deformation. The slit directions are orthogonal to the grooves of the support column, forming a "deformation transmission channel." For example, when the housing expands along the axis, the groove of the first support column allows for slight longitudinal movement, causing elastic tension / compression at the slit of the first connecting rod, preventing stress from being transmitted to the interior of the housing.

[0047] In some embodiments, the first support column is a semi-cylindrical structure with a groove in the diametrical direction, and the second support column is a semi-cylindrical structure with a groove in the semi-circular plane direction. The groove direction of the first support column is perpendicular to the groove direction of the second support column. Orthogonal calibration of the groove directions of the support columns is achieved through positioning fixtures, ensuring that the groove of the first support column is in the same direction as the machine housing axis, and the groove of the second support column is perpendicular to it, forming a precise deformation absorption coordinate system.

[0048] By using a customized "L-shaped orthogonal positioning template", guide grooves are set on both sides of the template, which are parallel to the housing axis (Y-axis) and perpendicular to the housing axis (X-axis). The width of the guide grooves matches the bottom dimension of the support column (error ±0.02mm). The template is fixed to the preset installation area at the bottom of the housing, so that the Y-axis guide groove of the template is aligned with the laser emission direction (axis) of the housing (calibrated by a laser collimator). The first support column is embedded in the Y-axis guide groove, ensuring that its diameter groove is along the direction of the guide groove (i.e., the direction of the housing axis). The second support column is embedded in the X-axis guide groove, ensuring that its semi-circular plane groove is along the direction of the vertical axis. An M3-M5 threaded blind hole is opened at the top of the support column, aligned with the studs pre-embedded at the bottom of the housing, and tightened with a torque wrench with a torque of 8-12 N*m to ensure that the support column does not shift under vibration, while the grooved area maintains free deformation capability.

[0049] In some embodiments, the installation through holes are located using a three-dimensional coordinate system to ensure that the spacing between the support columns and the through holes of the connecting rods are aligned, thereby ensuring the spatial geometric accuracy of the deformation absorption structure.

[0050] A local coordinate system is established with the geometric center of the bottom of the casing as the origin, the casing axis as the Y-axis, the vertical axis as the X-axis, and the vertical direction as the Z-axis. The through-hole positioning method uses a coordinate measuring machine (CMM) to measure the coordinates of the through holes for the four pre-set support columns at the bottom of the machine housing (first support column: (X1,Y1,Z0), (X1,Y2,Z0); second support column: (X3,Y3,Z0), (X3,Y4,Z0)). This ensures that the lateral spacing |X3-X1| and the longitudinal spacing |Y3-Y1| conform to the design drawings (error ±0.1mm). The coordinates of the through holes for the first and second connecting rods are then measured, requiring a deviation of ≤0.05mm from the corresponding support column through holes in the Z-axis direction (achieved through pre-positioning by inserting locating pins into the through holes). Tolerance control employs precision machining to ensure consistent groove depth (e.g., 0.5mm groove) and avoid tilting torque during screw tightening, which could affect the directionality of deformation absorption.

[0051] In some embodiments, by specifying the screw torque parameters of the fixing structure, the mechanical conditions of rigid fixing of the housing and elastic deformation absorption are balanced to avoid excessive constraint or insufficient rigidity.

[0052] The torque setting is based on the initial stress of the connecting rod under different torques calculated by finite element simulation (such as ANSYS), and the critical conditions are set: the lower limit torque ensures that the screw preload is greater than or equal to the static load of the housing (such as the shear force caused by its own weight), and prevents rigid displacement (such as translation or overturning); the upper limit torque ensures that the preload is less than the elastic limit load of the connecting rod material (such as when the yield strength of spring steel is 600MPa, the stress corresponding to the preload is ≤400MPa). During installation, use a torque wrench to tighten each fixing screw sequentially to the preset torque (e.g., 10N*m±10%), following the principle of "alternating tightening diagonally" to avoid stress concentration. After tightening, use a laser vibration meter to detect the rigidity mode of the housing to confirm that there is no low-frequency rigid displacement (e.g., frequency > 50Hz). At the same time, manually apply a small lateral force (5-10N) and observe whether the cut of the connecting rod produces recoverable deformation to verify the effectiveness of the elastic channel.

[0053] In some embodiments, by providing two temperature load simulation schemes, the uniform temperature change of the casing is ensured, and the thermal expansion / contraction under actual working conditions is realistically reproduced.

[0054] Option 1: Overall loading into a temperature control chamber. This involves placing the entire laser unit into a programmable temperature control chamber with a matching volume (e.g., accuracy ±0.5℃, temperature change rate 1℃ / min), setting a temperature cycling curve (e.g., -20℃→+60℃→-20℃, holding each stage for 30 minutes); attaching 3-5 K-type thermocouples to the surface of the housing, and monitoring the temperature in real time using a data acquisition card to ensure that the temperature difference at each measuring point is ≤1℃, avoiding uneven deformation caused by localized overheating; Option 2: Localized active temperature control by attaching flexible heating elements (power density 0.5-1W / cm²) to the bottom and sides of the casing. 2It uses a semiconductor cooling chip and a PID controller to simulate temperature changes at a preset gradient (e.g., 0.5℃ / min); in conjunction with an infrared thermal imager to scan the surface of the housing, it adjusts the heating / cooling power to ensure that the temperature distribution uniformity error is ≤2%, making it suitable for rapid on-site testing scenarios.

[0055] In some embodiments, a displacement sensor is used to achieve real-time quantitative detection of the slit deformation, and a threshold is set to determine whether the deformation absorption capacity meets the standard. Sensor selection: A high-precision LVDT linear displacement sensor (range ±1mm, accuracy 0.001mm) is used. The sensor probe is fixed to one side of the slit on the connecting rod, and a reflector or induction target is installed on the other side. Data acquisition is achieved by connecting the sensor signal to a dynamic data acquisition instrument (sampling frequency 100Hz), which simultaneously records the temperature change curve and the slit opening and closing displacement (ΔW). The preset threshold is set according to the laser accuracy requirements (e.g., in precision machining scenarios: lateral ΔW ≤ 0.3mm, longitudinal ΔW ≤ 0.4mm). Exceeding the upper limit indicates insufficient stiffness, and falling below the lower limit indicates excessive stiffness. When ΔW exceeds the threshold range for three consecutive temperature cycles, the parameter optimization process is triggered to avoid interference from random errors.

[0056] In some embodiments, a visual recognition system is introduced as an auxiliary detection method, and the change in cut size is calculated by image algorithm to form multimodal detection redundancy.

[0057] The hardware configuration includes a 12-megapixel industrial camera (with a 50mm fixed-focus lens, 0.05mm / pixel resolution) mounted above the inspection area, and a low-angle ring LED light source (to reduce glare interference). The image processing workflow involves acquiring images of the cut seam under initial conditions (25℃) and extracting the coordinates of the edges on both sides of the cut seam using an edge detection algorithm (such as the Canny operator). Real-time image acquisition under temperature load calculates the edge coordinate difference ΔPixel, converting it into the actual displacement ΔW (ΔW = ΔPixel × pixel size). The data processing module (such as a PLC or industrial computer) automatically compares the visual inspection values ​​with the displacement sensor values; a calibration alarm is triggered when the deviation exceeds 5%. Upon completion of the inspection, a PDF report containing the temperature-deformation curve and the number of times the threshold was exceeded is generated for tracing the installation quality.

[0058] In some embodiments, by establishing a connecting rod thickness parameter library, alternative specifications are automatically matched based on the test results, and the deformation absorption parameters are accurately optimized through iterative testing. Parameter library construction: A mapping table of "connecting rod thickness h (2mm, 2.5mm, 3mm, 3.5mm) - deformation ΔW (theoretical value)" is established in advance through finite element simulation or orthogonal experiments and stored in the control system database; Replacement strategy: If the detected ΔW > the upper limit value (e.g., 0.5mm), it is determined that the stiffness is insufficient, and a connecting rod with a thickness of h + 0.5mm is retrieved (e.g., if 2mm is currently used, it is replaced with 2.5mm); if ΔW < the lower limit value (e.g., 0.2mm), it is determined that the stiffness is excessive, and a connecting rod with a thickness of h - 0.5mm is retrieved; Iterative process: After each replacement, the loading and testing steps of embodiments 5-6 are repeated until ΔW falls into the design threshold (e.g., 0.2-0.4mm) for two consecutive tests, and the optimal thickness parameter is recorded in the equipment file.

[0059] In some embodiments, the method further includes: training historical test data using a machine learning algorithm to establish a mapping model between deformation and connecting rod thickness; the model input is real-time detected deformation data, and the output is recommended connecting rod thinning thickness parameters; the parameter library is automatically updated according to each test result to form an adaptive compensation strategy.

[0060] By leveraging machine learning to build an adaptive compensation model and training it with historical data to improve parameter optimization efficiency, an intelligent testing strategy is formed.

[0061] Data training involves collecting at least 50 sets of historical test data (including laser model, ambient temperature range, connecting rod thickness h, and measured ΔW), and training the model using Support Vector Regression (SVR) or Random Forest algorithms. The input is the measured value of ΔW, and the output is the recommended thickness h_recommend. Model deployment involves embedding the trained model into the data processing module, receiving the detection data in real time, and outputting optimization suggestions within 1 second (e.g., "Current ΔW = 0.6mm, it is recommended to replace the connecting rod with h = 3mm"). The self-updating mechanism automatically appends the latest data (including the optimized h and the final ΔW) to the training set after each test. Every 10 sets of data are accumulated, the model is incrementally updated to adapt to individual differences in different batches of lasers (e.g., deviations in the thermal expansion coefficient of the casing material).

[0062] This invention utilizes orthogonally distributed support column slots and connecting rod slits to absorb thermal deformation of the housing in both the axial and vertical directions, preventing stress concentration from affecting internal components and improving the long-term stability of the laser. By replacing connecting rods with different thicknesses, the elastic stiffness of the structure can be flexibly adjusted to adapt to the deformation absorption requirements of lasers of different power and size, enhancing the versatility of the solution. Through simulated temperature load and deformation detection, quantitative evaluation and parameter optimization of the installation structure can be achieved, avoiding the blindness of traditional experience-based design and ensuring that installation reliability meets the requirements of high-precision operating conditions. The preset torque design of the fixed structure limits the rigid displacement of the housing while allowing for the absorption of temperature stress through elastic deformation, balancing installation stability and deformation adaptability.
