Description

Technical Field

[0001] The present invention relates to the technical field of laser cladding, and specifically relates to a laser green repair metal remanufacturing equipment capable of variably adjusting the relationship between light and material. Background Art

[0002] At present, through the retrieval of patents related to laser cladding processing technology, it is found that in the existing patents with publication numbers CN101386111A for laser in-light wire feeding cladding method and in-light wire feeding device, CN106392314A for laser cladding feeding device, CN106583726A for laser multi-beam cladding device, CN107217257A for laser cladding device, and CN106583920A for laser cladding device, the nozzle structures all involve the structure of the nozzle enclosing powder or wire. These nozzle structures have certain common problems, such as: the nozzle and the laser beam are fixedly connected, or only the positional relationship between the two can be manually adjusted through screw through holes to calibrate the position of the laser beam and the nozzle to achieve the coaxiality of the light spot and the nozzle. However, the design of this kind of nozzle structure has the following pain points: 1. Nozzle without adjustment function: The nozzle has many parts and a long dimension chain, and the dimensional chain error in the manufacturing and assembly of parts is large, resulting in difficulty in coaxiality between the nozzle and the light spot in the actual product, which may cause the nozzle to deviate inside or outside the light spot (as shown in Figure 1 ), and then, under different scanning directions, the change in the positional relationship between the nozzle and the light spot makes the light spot unable to coaxially enclose the powder / wire, directly resulting in inconsistent cladding layer morphologies in each scanning direction, unable to guarantee the accuracy of complex three-dimensional forming, and at the same time, problems such as low powder utilization rate and poor roughness will occur.

[0003] 2. Nozzle with manual adjustment function: The adjustment range is limited, and it cannot be effectively adjusted in the face of large errors; moreover, the manual adjustment method has low efficiency, and it is difficult to accurately judge the precise position of the nozzle and the laser beam only by the naked eye, resulting in poor adjustment accuracy.

[0004] 3. Since the positional relationship between the light spot and the nozzle cannot be accurately and controllably adjusted dynamically, in some special application scenarios, when a certain offset between the nozzle and the light spot is required to form a special-shaped cladding layer, the nozzle structures of the disclosed patents cannot carry out similar repair work, restricting the application expansion of this technology. Summary of the Invention

[0005] The present invention provides a laser green repair metal remanufacturing equipment capable of variably adjusting the relationship between light and material to solve the problems raised in the above background art.

[0006] To solve the above technical problems, the technical solutions adopted by the present invention are: A laser green repair metal remanufacturing equipment with variable adjustment of the light-material relationship, including a laser cladding nozzle head composed of a laser beam assembly and a nozzle assembly, and a moving platform connected to the outside of the nozzle assembly through a first connecting rod. The laser beam assembly is detachably connected to the moving platform through a second connecting rod, and the nozzle assembly moves along the X-axis direction or the Y-axis direction through the moving platform to achieve a coaxial state with the multi-beams generated by the laser beam assembly or form an offset setting, and a CCD camera for monitoring the positional relationship between the nozzle assembly and the multi-beams is provided on the laser cladding nozzle head.

[0007] Preferably, the moving platform includes two symmetrically arranged Y-axis direction components, support sliders respectively sliding on the Y-axis direction components, X-axis direction components connected to the support sliders and forming a symmetric arrangement, and a central ring sliding on the X-axis direction components.

[0008] Preferably, the Y-axis direction components include two symmetrically arranged bases, first motors respectively installed on the bases, first synchronous pulleys respectively connected to the output ends of the first motors, a first synchronous belt meshingly connected to the two first synchronous pulleys, and a straight slide bar installed between the two bases. The straight slide bar movably penetrates the surface of the support slider, and a part of the belt body of the first synchronous belt is connected to the support slider through a clamping member.

[0009] Preferably, the X-axis direction components include second motors respectively installed on the two support sliders, second synchronous pulleys respectively connected to the output ends of the second motors, a second synchronous belt meshingly connected to the two second synchronous pulleys, and two bent slide bars installed between the two support sliders. The central ring is slidably arranged on the outer walls of the two bent slide bars, and a part of the belt body of the second synchronous belt is connected to the central ring through a clamping member.

[0010] Preferably, the support slider includes a slider and support plates connected to the upper and lower end faces of the slider, and the second motor is fixedly installed on the support plate.

[0011] Preferably, the straight slide bar movably penetrates the slider, and the first synchronous belt is connected to the slider.

[0012] Preferably, a plurality of side holes are formed through the surface of the central ring, and two side holes on the same side are taken as a group among the plurality of side holes, and the two bent slide bars are respectively arranged in two groups of the side holes.

[0016] By adopting the above technical solutions, the beneficial effects achieved by the present invention are as follows: In the present invention, through the cooperation of the dual motors and the CCD camera, the positional relationship between the nozzle assembly and the light spot can be adjusted in real time. When the light spot and the nozzle are coaxially related, the dimensional accuracy consistency of the repair layers in all directions can be ensured, effectively improving the forming accuracy of complex parts; in some special application scenarios, the nozzle and the light spot can be dynamically offset to form a special-shaped cladding layer, which can provide strong technical support for carrying out green repair work in special scenarios.

[0017] In the present invention, the dual motors are used to drive the dynamic movement of the nozzle assembly in the X-axis direction or the Y-axis direction, and the CCD camera is used to observe the positional relationship between the light spot and the nozzle, so as to more accurately identify the positions of the nozzle and the light spot, and dynamically adjust the positions of the nozzle and the light spot according to the application scenario, reducing the problems of low efficiency and poor accuracy in traditional manual adjustment; at the same time, the real-time adjustment of the positional relationship between the nozzle assembly and the light spot also prevents the problem of part of the powder spilling outside the light spot, resulting in powder waste, and thus can effectively improve the powder utilization rate.

[0032] In order to more clearly understand the above objects, features and advantages of the present invention, the following further describes the present invention with reference to the accompanying drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments may be combined with each other.

[0033] In the following description, many specific details are set forth in order to provide a thorough understanding of the present invention. However, the present invention may be practiced in other ways different from those described herein. Therefore, the present invention is not limited by the limitations of the specific embodiments disclosed in the following specification.

[0034] As Figures 2 - 13 shown, the present invention provides a laser green repair metal remanufacturing equipment capable of variably adjusting the light-material relationship, including a laser cladding spray head 3 composed of a laser beam assembly 1 and a nozzle assembly 2, and a moving platform 5 connected to the outside of the nozzle assembly 2 through a first link 4. The laser beam assembly 1 is detachably connected to the moving platform 5 through a second link 6, and the nozzle assembly 2 moves along the X-axis direction or the Y-axis direction through the moving platform 5 to achieve a coaxial state or a deviation setting with the multi-beams generated by the laser beam assembly 1. A CCD camera 7 for monitoring the positional relationship between the nozzle assembly 2 and the multi-beams is provided on the laser cladding spray head 3. It should be noted that when the multi-beams generated by the laser beam assembly 1 are projected onto the substrate below the nozzle assembly 2, a light spot can be formed (as Figure 13 shown).

[0035] Furthermore, a laser green repair metal remanufacturing equipment capable of variably adjusting the light-material relationship further includes a control center for controlling the moving platform 5. The control center is electrically connected to the CCD camera 7, and based on the acquisition data of the CCD camera 7, the control center controls the moving platform 5 to drive the nozzle assembly 2 to move in the X-axis direction or the Y-axis direction, so as to ensure that the moving platform 5 can accurately regulate the relative positional relationship between the nozzle assembly 2 and the light spot.

[0036] It should be emphasized that the control center has the function of receiving acquisition data and implementing control on the corresponding equipment based on this data. Such a control center capable of realizing data reception and equipment control belongs to the technical content that those skilled in the art can obtain by common sense. Therefore, it will not be elaborated in detail herein.

[0037] Among them, a flexible pipe 13 for conveying powder is arranged inside the nozzle assembly 2. In this solution, the flexible pipe 13 is used to replace the traditional powder conveying pipe to ensure that the flexible pipe can move flexibly with the nozzle assembly 2, so as to meet the powder conveying work requirements at different positions, promote the powder to form a special-shaped cladding layer, carry out green repair work in special scenarios, and effectively ensure the forming accuracy of complex parts.

[0038] Combined with Figure 10As shown, it should be emphasized that the laser beam assembly 1 of the laser cladding nozzle 3 includes a laser emitter, an upper cover, a support frame, and a beam splitter mechanism and a plurality of reflection focusing mirror mechanisms that are installed on the top of the support frame and placed inside the upper cover cavity. Among them, the plurality of reflection focusing mirror mechanisms are evenly arranged in an array with the beam splitter mechanism as the center. When the laser beam emitted by the laser emitter during operation is projected onto the beam splitter of the beam splitter mechanism through a path, the beam splitter can divide the laser beam into multiple beams and project them onto the reflection focusing mirrors of the corresponding reflection focusing mirror mechanisms. Then, the laser beams reflected by the reflection focusing mirrors can be projected onto the substrate through the reflection optical path through holes 14 on the support frame to form an envelope light spot. It should be noted that the beam splitter in the beam splitter mechanism is provided with at least two beam splitting surfaces, and each beam splitting surface is a plane. The reflection focusing mirrors in the plurality of reflection focusing mirror mechanisms respectively correspond to the beam splitting surfaces on the beam splitter one by one, so as to enable the reflection focusing mirrors to receive the reflected beams emitted by the laser emitter and simultaneously convert the reflected beams into focused beams. In this embodiment, three focused beams (laser beams) are used for illustration.

[0039] It should be noted that the multi-beam technology formed by the above-described laser cladding nozzle 3 is a well-known and publicly disclosed technology. For more details, reference can be made to the publicly cited patents in the background technology, and this article will not elaborate on it in more detail.

[0040] Combined with Figure 1 、 Figure 5 and Figure 6 As shown, as a further aspect, the moving platform 5 includes two symmetrically arranged Y-axis components 8, support sliders 10 that slide on the Y-axis components 8 respectively, X-axis components 9 that are connected to the support sliders 10 and are symmetrically arranged, and a center ring 11 that slides on the X-axis components 9. The nozzle assembly 2 is fixedly installed on the center ring 11 through a first link member 4, and the Y-axis component 8 is used to drive the support slider 10 to move along the Y-axis direction, and the X-axis component 9 is used to drive the center ring 11 to move along the X-axis direction.

[0041] As a further step, combined with Figure 3 As shown, the Y-axis component 8 includes two symmetrically arranged bases 81, first motors 82 that are respectively installed on the bases 81, first synchronous pulleys 83 that are respectively connected to the output ends of the first motors 82, a first synchronous belt 84 that is meshed and connected to the two first synchronous pulleys 83, and a straight slide bar 85 that is installed between the two bases 81. The straight slide bar 85 movably penetrates the surface of the support slider 10, and a part of the belt body of the first synchronous belt 84 is connected to the support slider 10 through a clamping member.

[0042] Among them, the first motor 82 is used to provide kinetic energy to drive the first synchronous pulley 83 to rotate. Further, the first synchronous pulley 83 can drive the support slide 10 to move back and forth via the first synchronous belt 84, so as to realize the position adjustment of the nozzle assembly 2 along the Y-axis direction, ensure that the nozzle assembly 2 can be accurately aligned with the light spot formed by multiple beams, ensure that the powder can be accurately delivered to the light spot action area, and improve the powder utilization rate. Moreover, the nozzle assembly 2 after the position adjustment along the Y-axis direction can also make the cladding layer be distributed in a biased manner, meet the repair requirements of special working conditions, and reduce processing defects.

[0043] As Figure 11 shown, when the repair area is irregular and the cross-sectional shape is an asymmetric cladding morphology distribution, it is necessary to adjust the position relationship between the nozzle assembly 2 and the light spot so that the cladding layer also shows a biased distribution, thereby meeting the repair requirements of special working conditions.

[0044] As a further step, as combined with Figure 4 shown, the X-axis direction assembly 9 includes a second motor 91 correspondingly installed on two support slides 10, second synchronous pulleys 92 respectively connected to the output ends of the second motor 91, a second synchronous belt 93 meshed with the two second synchronous pulleys 92, and two curved slide bars 94 installed between the two support slides 10. The central ring 11 is slidably arranged on the outer walls of the two curved slide bars 94, and a part of the belt body of the second synchronous belt 93 is connected to the central ring 11 through a clamping member.

[0045] Among them, the second motor 91 is used to provide kinetic energy to drive the second synchronous pulley 92 to rotate. Further, the second synchronous pulley 92 can drive the central ring 11 to move back and forth via the second synchronous belt 93, so as to realize the position adjustment of the nozzle assembly 2 along the X-axis direction, ensure that the nozzle assembly 2 can be accurately aligned with the light spot formed by multiple beams, ensure that the powder can be accurately delivered to the light spot action area, and improve the powder utilization rate. Moreover, the nozzle assembly 2 after the position adjustment along the X-axis direction can also make the cladding layer be distributed in a biased manner, meet the repair requirements of special working conditions.

[0046] As Figure 12 shown, when the repair area is irregular and the cross-sectional shape is a cladding morphology with a left-biased distribution or a right-biased distribution, it is necessary to adjust the position relationship between the nozzle assembly 2 and the light spot so that the nozzle corresponds to the biased position of the cladding layer, thereby meeting the repair requirements of special working conditions.

[0047] It should be noted that the clamping member described in this article is a synchronous belt pressing plate. The synchronous belt pressing plate is used to clamp and fix a part of the synchronous belt on the support slide 10 or the central ring 11 to ensure that the synchronous belt can be fixedly connected to the support slide 10 or the central ring 11, and to ensure that the synchronous belt moves synchronously with the support slide 10 or the central ring 11 during the transmission process, which is beneficial to realizing the movement of the nozzle assembly 2 in the X-axis direction or the Y-axis direction.

[0048] Combined with Figure 3 and Figure 4 As shown, as a further aspect, the support slide 10 includes a slider 101 and support plates 102 connected to the upper and lower end faces of the slider 101. The second motor 91 is fixedly installed on the support plate 102. The straight slide bar 85 movably penetrates through the slider 101. The straight slide bar 85 is used to support the slider 101, and the first synchronous belt 84 is connected to the slider 101. A part of the synchronous belt is clamped and fixed on the slider 101 by the synchronous belt pressing plate to ensure that the synchronous belt can be fixedly connected to the slider 101, and to realize the movement of the slider 101 following the first synchronous belt 84 during transmission, and to complete the movement of the nozzle assembly 2 in the Y-axis direction.

[0049] As a further aspect, a plurality of side holes 12 are formed through the surface of the central ring 11. Two side holes 12 on the same side are taken as a group among the plurality of side holes 12, and two bent slide bars 94 are respectively arranged in the two groups of side holes 12. Among them, the plurality of side holes 12 are respectively in an arc shape to adapt to the movement on the bent slide bar 94, which is beneficial to the nozzle assembly 2 to move in the X-axis direction.

[0050] Combined with Figure 9 As shown, it should be noted that in this solution, the bent slide bar 94 is designed to be bent, mainly to ensure that the bent slide bar 94 does not block the multiple light beams generated by the laser beam assembly 1, so as to ensure that the multiple light beams can be normally projected on the substrate or the cladding layer. More importantly, since the central ring 11 drives the nozzle assembly 2 to adjust in the X-axis or Y-axis direction always within the inner area of the light spot, so, in the case of a short adjustment distance, the central ring 11 will not cause a blocking phenomenon to the projection of the multiple light beams.

[0051] Combined with Figure 9 As shown, as a further aspect, the first link member 4 includes a plurality of short link rods 41 connected to the inner side wall of the central ring 11 and a first collar 42 commonly connected to one ends of the plurality of short link rods 41. The nozzle assembly 2 is arranged inside the first collar 42, and the plurality of short link rods 41 are respectively arranged in a staggered manner with a plurality of reflection optical path through holes 14 on the laser beam assembly 1. Among them, at least three short link rods 41 are provided, and the stability of the first collar 42 can be ensured through the three short link rods 41, and further the stability of the nozzle assembly 2 during use can be ensured.

[0052] As a further feature, the second link member 6 includes a plurality of long link members 61 connected to the base 81 and a second collar 62 commonly connected to one end of the plurality of long link members 61. The laser beam assembly 1 is disposed inside the second collar 62 and can be fixed inside the second collar 62 by means of bolt connection or snap connection, facilitating the picking of the laser beam assembly 1 by the operator. The connection between the laser beam assembly 1 and the second collar 62 includes, but is not limited to, bolt connection or snap connection, and may also be other well-known and publicly disclosed fixing methods, which will not be introduced one by one herein. It should be noted that the nozzle assembly 2 is also connected to the first collar 42 by the same fixing structure.

[0053] The working principle and usage process of the present invention are as follows: The CCD camera 7 is used to observe the positional relationship between the light spot and the nozzle assembly 2 in real time, and the first motor 82 or the second motor 91 is controlled to start based on the positional relationship data. When the first motor 82 operates, the nozzle assembly 2 can be moved in the Y-axis direction through the cooperation of the first synchronous pulley 83, the first synchronous belt 84, and the support slider 10. When the second motor 91 operates, the nozzle assembly 2 can be moved in the X-axis direction through the cooperation of the second synchronous pulley 92, the second synchronous belt 93, and the center ring 11, enabling the positional relationship between the nozzle assembly 2 and the light spot to be adjusted in real time. When performing arbitrary direction scanning, the positional relationship between the light spot and the nozzle always maintains a coaxial relationship, improving the powder utilization rate and the forming accuracy of complex parts. Moreover, in some special application scenarios, the movement adjustment of the nozzle assembly 2 in the X-axis direction or the Y-axis direction can dynamically offset the nozzle assembly 2 and the light spot to form a special-shaped cladding layer, thereby carrying out special scenario green repair work to meet the repair requirements of special working conditions.

[0054] In summary, the present invention adopts "dual motors (i.e., the first motor 82 and the second motor 91) + CCD camera 7" to coaxially arrange the nozzle assembly 2 and the light spot inside the light, and enables the nozzle assembly 2 to have a dynamic adjustment function. Therefore, compared with the traditional technology without nozzle adjustment function, the advantages of this solution are as follows: The positional relationship between the nozzle assembly 2 and the light spot can be adjusted in real time. When the nozzle assembly 2 is adjusted to the center position of the light spot, arbitrary direction scanning can be achieved. At the same time, the positional relationship between the light spot and the nozzle is always kept consistent, effectively ensuring the coaxial relationship. Thus, the molten pool morphology remains consistent in all scanning directions, and the corresponding repair morphologies in all directions also remain consistent, thereby ensuring the dimensional accuracy consistency of the repair layers in all directions and effectively improving the forming accuracy of complex parts. At the same time, it also prevents some powder from overflowing outside the light spot, resulting in powder waste, and thus effectively improves the powder utilization rate.

[0055] Compared with the traditional technology with manual nozzle adjustment function, the advantages of this solution are as follows: The dynamic movement of the nozzle assembly in the 2X-axis direction or the Y-axis direction can be driven by a dual-motor (i.e., the first motor 82 and the second motor 91), and the position relationship between the light spot and the nozzle can be observed through the CCD camera 7, so as to more accurately identify the positions of the nozzle and the light spot, dynamically adjust the positions of the nozzle and the light spot according to the application scenario, and reduce the problems of low efficiency and poor accuracy in traditional manual adjustment. Moreover, since the position relationship between the light spot and the nozzle can be precisely and dynamically adjusted, in some special application scenarios, the nozzle and the light spot can be dynamically offset to form a special-shaped cladding layer, which can provide strong technical support for carrying out green repair work in special scenarios.
