Description

Technical Field

[0001] This utility model relates to the field of laser cladding technology, and more specifically, to a dual-station alternating laser cladding workstation. Background Technology

[0002] Laser cladding technology is an advanced surface engineering and additive manufacturing technology. Its principle involves using a high-energy laser beam to simultaneously melt the cladding material and a thin layer on the substrate surface, rapidly solidifying them to form a dense, metallurgically bonded coating. A laser cladding workstation is a complete equipment system that integrates and implements this technology. It typically consists of core modules such as a high-power laser, a precision motion system, a coaxial powder feeding device, an inert atmosphere protection system, and specialized fixtures and control systems. This workstation is widely used in the remanufacturing, surface strengthening, and functional repair of critical mechanical components. It can prepare high-performance wear-resistant, corrosion-resistant, or high-temperature-resistant coatings on damaged or worn parts, significantly extending the service life of components and possessing significant economic and environmental value.

[0003] To improve the production efficiency and equipment utilization of laser cladding processing, dual-station alternating laser cladding workstations have become an important development direction. These workstations typically feature two alternating processing stations. Their basic operating mode is as follows: while a workpiece is undergoing laser cladding at one station, the operator can safely disassemble the already processed workpiece and prepare for clamping the workpiece to be processed at the other station. Once the current processing cycle is complete, the equipment quickly processes the workpiece at the other station by rotating or translating the worktable or switching the laser processing head, thus overlapping processing and loading / unloading times and minimizing equipment downtime. Existing technical solutions mainly focus on the switching accuracy of the laser beam path, synchronous control of dual-station motion, and overall layout optimization, aiming to ensure processing continuity while maintaining the consistency and stability of processing parameters at each station.

[0004] However, existing dual-station alternating laser cladding workstations still have certain technical limitations in practical applications, especially in terms of the versatility and adaptability of the station fixtures. Due to the huge differences in size, shape and structure of the metal parts to be clad (such as shafts, discs, and irregular molds), most existing workstations use special fixtures for specific parts or general-purpose fixtures with only limited adjustment functions. This rigid or semi-rigid clamping method makes it difficult to flexibly and dynamically adjust the posture and adaptively stabilize the clamping according to the complex and ever-changing shape of the parts. This may lead to low clamping efficiency, insufficient repeatability, or uneven cladding layer and reduced bonding strength due to uneven clamping force distribution and part micro-vibration during laser processing.

[0005] For example, Chinese patent application No. 202323432301.5, entitled "A Laser Cladding Workstation for Hardware Cutlery," discloses a dual-station device for cladding cutlery-type workpieces. Although this design enables alternating operation of the stations, its workpiece clamping part mainly uses specific positioning blocks or simple calipers that match the shape of the cutlery for fixation. This clamping structure may be effective for cutlery bodies with regular shapes, but it cannot adapt to other metal parts with complex curved surfaces, asymmetry, or weak structures. When cladding is required for more diverse industrial parts, this clamping method exposes the disadvantages of poor versatility and cumbersome adjustment, making it difficult to quickly and accurately fix different parts in the optimal processing posture, thus affecting the stability and reliability of the laser cladding process. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies: Existing dual-station alternating laser cladding workstations suffer from limitations in the versatility and adaptability of their workstation fixtures. Due to the significant differences in size, shape, and structure of the metal parts to be clad, the rigid or semi-rigid clamping methods of existing workstations make it difficult to flexibly and dynamically adjust the posture and adaptively stabilize the clamping according to the complex and varied outlines of the parts. This can lead to low clamping efficiency, insufficient repeatability, or uneven cladding layer and reduced bonding strength due to uneven clamping force distribution and part micro-vibration during laser processing. Therefore, this invention proposes a dual-station alternating laser cladding workstation.

[0007] The specific technical solution is as follows: a dual-station alternating laser cladding workstation, including a dual-station assembly installed inside the work cabinet, the dual-station assembly including two clamping components, the clamping components being used to clamp metal parts and perform laser cladding inside the work cabinet; The clamping components include: The guide rails are installed inside the work cabinet; Two clamping abutments are symmetrically distributed on the guide rail. These clamping abutments are slidably mounted on the guide rail, and their positions are adjusted via an electric telescopic rod C. Each clamping abutment includes a clamping plate structure, which is used for flexible posture adjustment and adaptive stable clamping according to the shape and contour of the metal part. This improves clamping efficiency, ensures high repeatability and positioning accuracy, and provides uniform force distribution during laser processing, which is beneficial for uniform cladding on the metal part and enhances bonding strength.

[0008] A further technical solution of this utility model is that the dual-station assembly further includes: The rotary table is assembled inside the work cabinet; Two support beams are distributed on both sides of the rotary table; the support beams are fixed integrally with the rotary table; the two support beams correspond one-to-one with two clamping assemblies, and the clamping assemblies are mounted on the support beams.

[0009] A further technical solution of this utility model is that the clamping and abutting member also includes: The column is slidably mounted on the guide rail; The upright plate is integrally fixed to the top of the column; A horizontal plate is fixed vertically to the end of the vertical plate; a clamping plate structure is fixed to the horizontal plate.

[0010] A further technical solution of this utility model is that the clamping plate structure includes: Multiple unit clamping plates are arranged in a straight line; the unit clamping plates are used to directly act on metal parts; Multiple electric telescopic rods A are arranged in a one-to-one correspondence with multiple unit clamping plates; the multiple electric telescopic rods A are sequentially distributed among the multiple unit clamping plates; the multiple electric telescopic rods A and the multiple unit clamping plates are arranged in a straight line.

[0011] A further technical solution is provided, wherein the unit clamping plate comprises: The drive base is mounted on the end of the electric telescopic rod A; A clamping plate is assembled at the output end of the drive base; the drive base provides rotational power to the clamping plate to drive the clamping plate to rotate and adjust its angle to find a support point.

[0012] A further technical solution, the drive base includes: The support plate is fixed to the end of the electric telescopic pole A; A rotating shaft passes through the support plate; the rotating shaft and the support plate are rotatably assembled via bearings; a clamping plate is assembled at one end of the rotating shaft. A drive motor is mounted on a support plate; the other end of the shaft is fixed on the output shaft of the drive motor, and the drive motor is used to provide rotational power to the shaft.

[0013] The support plate consists of a bottom plate and a top plate, with a rotating shaft passing through the top plate. The bottom plate is fixed to the end of the electric telescopic rod A. An electric telescopic rod D is installed between the bottom plate and the top plate, which is used to adjust the distance between the bottom plate and the top plate, thereby adjusting the height of the clamping plate.

[0014] The clamping plate includes: A support plate is fixed to one end of a rotating shaft; the rotating shaft is fixed in the middle of the support plate. Two electric telescopic rods B are distributed at both ends of the support cross plate; the electric telescopic rods B are directly fixed to the support cross plate. A clamping plate is assembled on the end of the electric telescopic rod B away from the supporting cross plate; the clamping plate and the electric telescopic rod B are rotatably assembled.

[0015] The clamping plate is covered with a soft pad.

[0016] Compared with existing technologies, this utility model of a dual-station alternating laser cladding workstation has the following advantages: The dual-station assembly uses its two clamping components to perform alternating dual-station laser cladding work inside the work cabinet. During this process, the two clamping abutments of the clamping components are controlled by the extension and retraction of the electric telescopic rod C to clamp the metal parts together. The clamping plate structure is used to flexibly adjust the posture and adaptively stabilize the clamping according to the shape contour of the metal parts, thereby improving clamping efficiency, high repeatability and positioning accuracy, and uniform force distribution during laser processing, which is conducive to uniform cladding layer of metal parts and improves bonding strength. When the two clamping abutments of the clamping assembly are brought together to clamp metal parts, the electric telescopic rod C extends and retracts to adjust the height of the drive motor and the clamping plate, thus finding a force support point in the Z-axis direction. The drive motor provides rotational power to the shaft, adjusting the angle of the clamping plate to find a force support point in the plane formed by the Z and X axes. The clamping plate is flipped using one of the two electric telescopic rods B extending while the other retracts, thus finding a force support point in the plane formed by the X and Y axes. The two electric telescopic rods B extend or retract synchronously to find a force support point in the Y-axis direction. Finally, the distance between multiple unit clamping plates is adjusted in the X-axis direction by the electric telescopic rod A, enabling the clamping plate structure to flexibly adjust its posture and adaptively stabilize the clamping according to the shape contour of the metal parts. Traditional rigid clamps apply force only at a few points, which can easily lead to stress concentration or insufficient support. This application, through multi-dimensional adjustment, enables multiple clamping plates to contact the surface of the component from different directions and angles. These discrete contact points together constitute a uniformly distributed, adaptively enveloping "contour-based closed-loop force field." This force field not only fixes the workpiece macroscopically, but also significantly suppresses the high-frequency micro-amplitude vibration of the component caused by thermal stress release and molten pool flow impact during laser cladding. This is something that single-dimensional adjustment clamps cannot achieve. The suppression of vibration directly results in a finer grain, denser structure, and reduced porosity in the cladding layer, significantly improving the fatigue life of the cladding layer. Laser cladding is a localized rapid thermal cycling process, which causes uneven thermal expansion and contraction of the workpiece. In this application, each electric drive unit has the ability to maintain or fine-tune its position in real time. When thermal deformation of the workpiece is detected or predicted by a preset program, the amount of expansion and contraction in each dimension can be dynamically fine-tuned. In particular, electric telescopic rods A and B can make way for or follow the thermal deformation trend of the metal parts without loosening the clamp. This avoids the risk of additional stress or even cracking inside the workpiece caused by the constraint of thermal deformation by traditional rigid clamps, and achieves flexible constraint, ensuring the clamping stability and workpiece integrity of the entire thermal processing process. The complex, experience- and intuition-dependent manual alignment and multi-point clamping process is broken down into quantifiable and programmable standard mechanical actions across five dimensions. For any new metal part, the operator only needs to perform a simple initial placement and call the corresponding program to automatically complete precise alignment and adaptive clamping. This reduces the reliance on the operator's professional skills and experience, enabling the clamping of complex parts to be completed quickly and in a standardized manner. This is beneficial for ensuring product quality consistency in mass production and remanufacturing, and reduces personnel training costs. Attached Figure Description

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with specific embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the protection scope of this utility model.

[0020] In this embodiment of the utility model, such as Figures 1-5 As shown: A dual-station alternating laser cladding workstation includes a dual-station assembly 2 installed inside a work cabinet 1. The dual-station assembly 2 includes two clamping components 23, which are used to clamp metal parts and perform laser cladding inside the work cabinet 1. It should be noted that: apart from the work cabinet 1 and the dual-station assembly 2, the components of the laser cladding workstation not described are existing technologies. Their detailed structures can be found in existing literature and journals, and they can also be purchased directly from the market, or the components can be purchased from the market and assembled, etc.; they are not the subject of this invention, and will not be described in detail here, nor are they shown in the accompanying drawings. Clamping assembly 23 includes: Guide rail 24 is installed inside work cabinet 1; Two clamping abutments 25 are symmetrically distributed on the guide rail 24; the clamping abutments 25 are slidably assembled on the guide rail 24, and the positions of the two clamping abutments 25 on the guide rail 24 are adjusted by the extension and retraction control of the electric telescopic rod C; the clamping abutments 25 include a clamping plate structure 29, which is used to flexibly adjust the posture and adaptively stabilize the clamping according to the outline of the metal parts.

[0021] Therefore, regarding the versatility and adaptability of existing dual-station alternating laser cladding workstations' station fixtures, the metal parts to be clad vary greatly in size, shape, and structure. The rigid or semi-rigid clamping methods of existing workstations struggle to flexibly and dynamically adjust the posture and adaptively stabilize the clamping according to the complex and varied contours of the parts. This can lead to low clamping efficiency, insufficient repeatability, or uneven cladding layer and reduced bonding strength due to uneven clamping force distribution and part micro-vibration during laser processing. This application addresses these issues by: The dual-station assembly 2 uses its two clamping components 23 to perform alternating dual-station laser cladding work inside the work cabinet 1. During this process, the two clamping abutments 25 of the clamping components 23 are controlled by the extension and retraction of the electric telescopic rod C to clamp the metal parts together. The clamping plate structure 29 is used to flexibly adjust the posture and adaptively stabilize the clamping according to the shape contour of the metal parts, thereby improving clamping efficiency, high repeatability and positioning accuracy, and uniform force distribution during laser processing, which is conducive to uniform cladding layer of metal parts and improves bonding strength.

[0022] In this embodiment of the utility model, such as Figure 2 As shown: The dual-station assembly 2 also includes: Rotary table 22 is assembled inside work cabinet 1; Two support beams 21 are distributed on both sides of the rotary table 22; the support beams 21 are integrally fixed with the rotary table 22; the two support beams 21 correspond one-to-one with two clamping components 23, and the clamping components 23 are mounted on the support beams 21.

[0023] In this embodiment of the utility model, such as Figure 3 and Figure 4 As shown: The clamping and abutting member 25 further includes: The column 26 is slidably mounted on the guide rail 24; The upright plate 27 is integrally fixed to the top of the column 26; A horizontal plate 28 is vertically fixed to the end of the vertical plate 27; a clamping plate structure 29 is fixed to the horizontal plate 28.

[0024] In this embodiment of the utility model, such as Figure 5 and Figure 6 As shown: The clamping plate structure 29 includes: Multiple unit clamping plates 292 are arranged in a straight line; the unit clamping plates 292 are used to directly act on the metal parts. Multiple electric telescopic rods A291 are arranged in a one-to-one correspondence with multiple unit clamping plates 292; the multiple electric telescopic rods A291 are sequentially distributed among the multiple unit clamping plates 292; the multiple electric telescopic rods A291 and the multiple unit clamping plates 292 are arranged in a straight line.

[0025] Further technical solutions, such as Figure 5 and Figure 6 As shown: The unit clamping plate 292 includes: Drive base 293 is mounted on the end of electric telescopic rod A291; The clamping plate 294 is assembled at the output end of the drive base 293; the drive base 293 provides rotational power to the clamping plate 294 to drive the clamping plate 294 to rotate and adjust the angle to find the force support point.

[0026] like Figure 6 and Figure 7 As shown: The drive base 293 includes: Support plate 2932 is fixed to the end of electric telescopic pole A291; A rotating shaft 2933 passes through the support plate 2932; the rotating shaft 2933 and the support plate 2932 are rotatably assembled via bearings; a clamping plate 294 is assembled at one end of the rotating shaft 2933. The drive motor 2931 is mounted on the support plate 2932; the other end of the rotating shaft 2933 is fixed on the output shaft of the drive motor 2931, and the drive motor 2931 is used to provide rotational power for the rotating shaft 2933.

[0027] like Figure 7 As shown: The support plate 2932 is divided into a bottom plate and a top plate, and the rotating shaft 2933 passes through the top plate; the bottom plate is fixed to the end of the electric telescopic rod A291; an electric telescopic rod D is assembled between the bottom plate and the top plate, and the electric telescopic rod D is used to adjust the distance between the bottom plate and the top plate, so as to adjust the height of the clamping plate 294.

[0028] like Figure 6 and Figure 8 As shown: The clamping plate 294 includes: A support plate 2941 is fixed to one end of a rotating shaft 2933; the rotating shaft 2933 is fixed at the middle position of the support plate 2941. Two electric telescopic rods B2942 are distributed at both ends of the support horizontal plate 2941; the electric telescopic rods B2942 are directly fixed to the support horizontal plate 2941. The clamping plate 2943 is assembled on the end of the electric telescopic rod B2942 away from the supporting cross plate 2941; the clamping plate 2943 and the electric telescopic rod B2942 are rotatably assembled.

[0029] like Figure 8 As shown: A soft pad 2944 is laid on the clamping plate 2943.

[0030] Therefore, when the two clamping abutments 25 of the clamping assembly 23 are brought closer together to clamp the metal parts by the extension and retraction control of the electric telescopic rod C, the electric telescopic rod D is activated to adjust the height of the drive motor 2931 and the clamping plate 294 to find the force support point in the Z-axis direction; the drive motor 2931 provides rotational power to the rotating shaft 2933 to adjust the rotation angle of the clamping plate 294 to find the force support point on the plane formed by the Z-axis and X-axis; the clamping plate 294 uses one of the two electric telescopic rods B2942 to extend and the other to shorten, so that the clamping plate 2943 flips to find the force support point on the plane formed by the X-axis and Y-axis; and the two electric telescopic rods B2942 extend or shorten synchronously to find the force support point in the Y-axis direction; finally, the distance between multiple unit clamping plates 292 is adjusted in the X-axis direction by the electric telescopic rod A291, so that the clamping plate structure 29 can flexibly adjust its posture and adaptively stabilize the clamping according to the shape contour of the metal parts.

[0031] It should be noted that: X-axis direction: The direction in which multiple electric telescopic rods A291 and multiple unit clamping plates 292 are linearly distributed; Y-axis direction: The direction in which the drive base 293 and the clamping plate 294 are linearly distributed; Z-axis direction: The direction in which the support plate 2932 is erected.

[0032] In summary: The dual-station assembly 2 utilizes its two clamping components 23 to achieve alternating dual-station laser cladding operations within the work cabinet 1; each clamping component 23's clamping abutment 25 incorporates a highly coordinated multi-degree-of-freedom adaptive attitude adjustment system. This system achieves intelligent, flexible, and stable clamping of irregularly shaped metal parts through five-dimensional coordinated adjustments. Z-axis height positioning: First, the electric telescopic rod D is started, driving the motor 2931 and the entire clamping plate 294 unit to move in the vertical direction (Z-axis) to find the primary vertical support reference point for the components.

[0033] Coarse adjustment of plane angle: After establishing the Z-axis reference, the drive motor 2931 works, driving the rotating shaft 2933 to rotate, thereby causing the clamping plate 294 to rotate in the ZX plane, completing the initial adaptation of the tilt angle of the parts.

[0034] Spatial attitude fine adjustment: Subsequently, the two electric telescopic rods B2942 inside the clamping plate 294 perform differential telescopic (one extends and one retracts), driving the clamping plate body 2943 to produce a flipping action, realizing micro-angle adjustment in the XY plane to fit the curved surface of the component.

[0035] Y-axis spacing fit: The two electric telescopic rods B2942 can also extend and retract synchronously, causing the clamping plate 2943 to move closer to or away from the parts in the Y-axis direction, so as to achieve lateral close fit or avoidance.

[0036] X-axis overall envelope: Finally, the overall spacing of multiple unit clamping plates 292 in the X-axis direction is adjusted by the electric telescopic rod A291 to form an adaptive envelope for parts with different widths or contour sizes.

[0037] Traditional rigid clamps apply force only at a few points, which can easily lead to stress concentration or insufficient support. This application, through multi-dimensional adjustment, enables multiple clamping plates 292 to make contact with the surface of the component from different directions and at different angles. These discrete contact points together constitute a uniformly distributed, adaptively enveloping "contour-like closed-loop force field". This force field not only fixes the workpiece macroscopically, but also significantly suppresses the high-frequency micro-amplitude vibration of the component caused by thermal stress release and molten pool flow impact during laser cladding. This is something that a single-dimensional adjustment clamp cannot achieve. The suppression of vibration directly results in a finer grain, denser structure, and reduced porosity in the cladding layer, significantly improving the fatigue life of the cladding layer.

[0038] Laser cladding is a localized, rapid thermal cycling process, which causes uneven thermal expansion and contraction of the workpiece. In this application, each electric drive unit has the ability to maintain or fine-tune its position in real time. When thermal deformation of the workpiece is detected or predicted by a preset program, the amount of extension and contraction in each dimension can be dynamically fine-tuned. In particular, electric telescopic rods A291 and B2942 can yield or follow the thermal deformation trend of the metal parts without loosening the clamp. This avoids the risk of additional stress or even cracking inside the workpiece caused by the constraint of thermal deformation by traditional rigid clamps, and achieves flexible constraint, ensuring the clamping stability and workpiece integrity throughout the entire thermal processing process.

[0039] The complex, experience- and intuition-dependent manual alignment and multi-point clamping process is broken down into quantifiable and programmable standard mechanical actions across five dimensions. For any new metal part, the operator only needs to perform a simple initial placement and call the corresponding program to automatically complete precise alignment and adaptive clamping. This reduces the reliance on the operator's professional skills and experience, enabling the clamping of complex parts to be completed quickly and in a standardized manner. This is beneficial for ensuring product quality consistency in mass production and remanufacturing, and reduces personnel training costs.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
