Description

Technical Field

[0001] This invention relates to the field of wheel hub processing technology, and more specifically, to an intelligent laser marking machine for wheel hub processing. Background Technology

[0002] Wheel hubs, especially carbon fiber wheel hubs, often require laser marking on their surface during the production process to identify brand, model and other information. Existing wheel hub laser marking equipment usually uses a fixed focal length ultraviolet laser generator in conjunction with a two-dimensional galvanometer scanning system. In actual processing, the operator first needs to manually clamp the wheel hub on a simple flat worktable or rotating fixture, and roughly align it by visual inspection or the red light of the equipment. Then, fixed parameters such as laser power, frequency and scanning speed are set to control the laser beam to scan and mark on the surface of the wheel hub.

[0003] However, when dealing with wheel hubs of different sizes, it is necessary to frequently change or adjust the fixture components manually, making it difficult to achieve rapid model changeover, resulting in low automation and seriously affecting production efficiency. Secondly, during the clamping and adjustment process, it is difficult to ensure that the center of the wheel hub of different sizes coincides precisely with the rotation center of the rotating mechanism, which can easily cause the marking position to shift on the circumference, affecting the aesthetics and consistency of the product. Summary of the Invention

[0004] In view of the problems existing in the prior art, the purpose of this invention is to provide an intelligent laser marking machine for wheel hub processing, which aims to solve the above-mentioned technical problems.

[0005] To solve the above problems, the present invention adopts the following technical solution.

[0011] As a further aspect of the present invention: the driving assembly further includes a threaded seat rotatably connected to the outer circular surface of the threaded rod, a hinge frame fixedly connected to the top of the threaded seat, and sliding plates fixedly connected to both sides of the outer surface of the hinge frame, with one side of the sliding plate slidably connected to a U-shaped limiting groove; an adjusting plate for supporting and adjusting the angle of the baffle is hinged inside the hinge frame.

[0012] As a further embodiment of the present invention: the adjustment mechanism further includes a gear ring fixedly connected to the inner side of the bottom end of the annular plate, and a second servo motor is fixedly installed on the upper surface of the base. A main gear is fixedly connected to the top end of the output shaft of the second servo motor, and the main gear meshes with the gear ring.

[0013] As a further aspect of the present invention: a suction mechanism for absorbing smoke is provided at the middle of the upper surface of the cylindrical support platform. The suction mechanism includes a No. 3 electric telescopic rod fixedly connected to the middle of the upper surface of the cylindrical support platform. A multi-hole suction head is fixedly connected to the top end of the No. 3 electric telescopic rod. A recycling tank is fixedly connected to one side of the bottom of the support platform. An electric suction pump is fixedly installed on the outer circular surface of the recycling tank. A first suction pipe is connected between the electric suction pump and the recycling tank. A second suction pipe is fixedly connected to one output end of the electric suction pump. One end of the second suction pipe passes through the cylindrical support platform and is fixedly connected to the multi-hole suction head.

[0014] As a further aspect of the present invention: an extension plate is fixedly connected to the top edge of the fan-shaped frame; a second electric telescopic rod is fixedly connected to the upper surface of the cylindrical support, and a U-shaped clamp is fixedly connected to the top of the second electric telescopic rod.

[0015] As a further aspect of the present invention: the upper surface of the pallet is also provided with a dust removal mechanism for wiping the surface of the wheel hub to be processed. The dust removal mechanism includes a column fixedly connected to the upper surface of the pallet, a hydraulic rod fixedly connected to one side of the top of the column, a connecting block fixedly connected to one end of the hydraulic rod, a No. 4 electric telescopic rod fixedly connected to the bottom of the connecting block, a load-bearing plate fixedly connected to the bottom of the No. 4 electric telescopic rod, an infrared sensor fixedly installed at the bottom of the load-bearing plate, and a spraying assembly provided on one side of the outer surface of the load-bearing plate.

[0016] As a further embodiment of the present invention: the spraying assembly includes a water storage tank fixedly connected to one side of the outer surface of the load-bearing plate, a fixing plate fixedly connected to the bottom of the water storage tank, and a wiping cotton board fixedly connected to the bottom of the fixing plate; a water pump is fixedly installed on the front side of the water storage tank, and a water pump is provided at one end with a water pumping pipe fixedly connected to the water storage tank, and at the other end with an atomizing spray pipe fixedly connected.

[0017] As a further embodiment of the present invention: the atomizing nozzle is fixedly installed on the load-bearing plate, and its nozzle is oriented toward the wiping cotton plate.

[0018] Compared with the prior art, the technical solution provided by the present invention has at least the following beneficial effects:

[0019] This solution incorporates a rotation mechanism, an adjustment mechanism, and a centering mechanism. After the wheel hub is transported to the support platform, a first servo motor drives the support platform to rotate, causing the bevel gear to mesh with the stationary gear disc. This, in turn, uses the drive assembly to automatically center and clamp the baffle from the outer ring inwards onto the wheel hub to be processed. During rotation, the spokes are aligned with the laser marking device. When necessary, a second servo motor assists in adjusting the degree of baffle convergence, enabling rapid adaptive changing and precise centering for wheel hubs of different sizes. This operation, with its automatic circumferential positioning requiring no manual intervention, allows for continuous marking of multiple spokes, significantly improving production efficiency, ensuring the consistency of the marking position on the circumference, and enhancing product aesthetics and marking quality.

[0020] By setting up an air suction mechanism, before laser marking the wheel hub, the No. 3 electric telescopic rod is activated to raise the multi-hole suction head to a suitable dust suction position, and the electric suction pump is activated simultaneously to suck the marking fumes into the collection tank through the second and first suction pipes for centralized collection. This operation not only achieves timely collection and storage of marking fumes, effectively solving the problem of fumes spreading and polluting the environment and affecting the health of operators, but also effectively prevents fumes from adhering to the laser marking lens, improving the stability of equipment operation and the clarity of marking.

[0021] By setting up a dust removal mechanism, the wiping cotton board is moved above the spokes to be marked via a hydraulic rod and a No. 4 electric telescopic rod. After being lowered to a suitable height using an infrared sensor, the water pump is activated to spray cleaning fluid evenly onto the wiping cotton board through an atomizing nozzle, thus wetting it. A rotating mechanism drives the hub to rotate, causing relative friction between the wiping cotton board and the hub surface, thereby achieving automatic cleaning of the hub surface. This effectively removes dust, oil, and impurities, solving the problems of low efficiency and uneven cleaning caused by manual wiping. It ensures the cleanliness of the hub surface before marking, significantly improving the clarity, contrast, and adhesion of the marking pattern. At the same time, the real-time distance detection of the infrared sensor avoids excessive squeezing damage, improving the safety and reliability of the equipment. Attached Figure Description

[0041] As shown in the figure, specific structures and devices are marked in the figure to clearly illustrate the structure of the embodiments of the present invention. However, this is only for illustrative purposes and is not intended to limit the present invention to this specific structure, device and environment. Those skilled in the art can adjust or modify these devices and environments according to specific needs. Detailed Implementation

[0042] The present invention provides an intelligent laser marking machine for wheel hub processing, which is described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, to make the embodiments more detailed, the following embodiments are the best and preferred embodiments, and those skilled in the art can use other alternative methods to implement some well-known technologies; moreover, the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit the present invention.

[0043] like Figures 1 to 9 As shown, this embodiment of the invention provides an intelligent laser marking machine for wheel hub processing, including a base 1, a sealing plate 2 slidably connected inside the base 1, a protective box 3 fixedly connected to the base 1, a support plate 31 fixedly connected to the top inside the protective box 3, a lifting platform 9 fixedly installed on one side of the upper surface of the support plate 31, an adjusting arm 10 fixedly connected to the output end of the lifting platform 9, and a laser marking device 11 fixedly installed at the output end of the adjusting arm 10; a rotating mechanism 4 for rotatably supporting the wheel hub to be processed is provided in the middle of the protective box 3, the rotating mechanism 4 includes a support platform 41 rotatably connected inside the protective box 3, a circular slot 42 is opened on the outer edge of the support platform 41, a fan-shaped frame 43 is circumferentially connected to the middle of the upper surface of the support platform 41, and limit grooves 44 are opened on both sides inside the fan-shaped frame 43;

[0044] The protective box 3 is also equipped with an adjustment mechanism 5 that works in conjunction with the rotating mechanism 4. The adjustment mechanism 5 includes an annular plate 51 embedded in the outer surface of the circular slot 42, and a toothed disc 52 is fixedly connected to the top of the annular plate 51.

[0045] The upper surface of the support platform 41 is provided with a centering mechanism 6 that works in conjunction with the adjustment mechanism 5 and the rotation mechanism 4. The centering mechanism 6 includes a limiting frame 61 that is slidably connected to the upper surface of the support platform 41. Both ends of the limiting frame 61 near the fan-shaped frame 43 are fixedly connected with sliders 62. The sliders 62 are slidably connected in the limiting groove 44. A baffle 64 is rotatably connected to one side inside the limiting frame 61. The limiting frame 61 is also provided with a drive assembly that works in conjunction with the gear plate 52. The rotation angle of the baffle 64 is changed by the drive assembly to complete the clamping and fixing of the wheel hub to be processed.

[0046] like Figures 1 to 9 As shown, the protective box 3 has a support plate 32 fixedly connected to both sides of its outer surface; the rotating mechanism 4 also includes a cylindrical support 46 fixedly connected to the middle of the bottom of the support platform 41, and a servo motor 47 for driving the cylindrical support 46 to rotate is fixedly installed in the middle of the upper surface of the base 1.

[0047] To address the problems of existing wheel hub laser marking equipment requiring frequent manual replacement or adjustment of fixture components when dealing with wheel hubs of different sizes, hindering rapid model changeover, and making it difficult to ensure precise alignment of the wheel hub center with the rotation center during manual clamping and adjustment, which can easily lead to circumferential offset of the marking position, the above-mentioned technical solution is adopted. This technical solution mainly consists of a rotating mechanism 4, an adjusting mechanism 5, and a centering mechanism 6. In operation, the entire device is first connected to a conveyor for transporting the wheel hub to be processed. The conveyor transports the wheel hub to be processed to the support platform 41, placing it on the upper surface of the fan-shaped frame 43. The first servo motor 47 is started, and its output shaft drives the cylindrical support 46 to rotate, which in turn drives the support platform 41 and the sector frame 43 fixedly connected to it to rotate synchronously. During the rotation of the support platform 41, the bevel gear 611 fixedly connected to the limit frame 61 rotates relative to and meshes with the stationary gear disk 52. Through the drive component, the baffle 64 is driven to converge and flip towards the center in the limit frame 61, clamping from the outer ring of the hub inward, realizing automatic centering and clamping of the hub. This clamping process does not require manual adjustment of the fixture, can quickly adapt to hubs of different sizes and specifications, and solves the problem of slow changeover in traditional equipment. At the same time, because the baffle 64 moves from the outer ring of the hub to the center, the baffle 611 rotates from the outer ring of the hub to the center. The outer ring precisely centers and clamps the wheel hub, ensuring that the center of the wheel hub coincides with the rotation center of the support platform 41, effectively avoiding defective products caused by positional misalignment during subsequent marking. While the baffle 64 clamps the wheel hub, the first servo motor 47 continuously drives the support platform 41 to rotate, causing the clamped wheel hub to rotate until one of its spokes moves directly below the laser marking device 11. At this point, the first servo motor 47 stops, the lifting platform 9 is activated, and the laser marking device 11 is adjusted to a suitable marking height via the adjusting arm 10, aligning with the spoke for laser marking. This process is automatically completed by the rotating mechanism 4. The circumferential position adjustment of the wheel hub eliminates the need for manual visual alignment or manual rotation, avoiding human error. After marking the current spoke, if marking other spokes is required, simply restart the servo motor 47 to rotate the support platform 41 so that the next spoke is aligned directly below the laser marking device 11, and repeat the marking operation. The entire process achieves automated coordination of wheel hub clamping and circumferential positioning, eliminating the need for repeated manual clamping or adjustment of the wheel hub position. The operation is convenient and precise, significantly improving production efficiency while ensuring the consistency of the marking position of each spoke on the circumference, effectively enhancing the product's aesthetics and marking quality.

[0048] like Figures 1 to 9As shown, the centering mechanism 6 also includes U-shaped limiting grooves 63 that are fixedly connected to both sides of the inner wall of the limiting frame 61. A cylindrical frame 65 is fixedly connected to the side of the limiting frame 61 near the fan-shaped frame 43. The drive assembly includes a first annular support 66 fixedly connected to the outer side of the inner wall of the limiting frame 61. A second annular support 67 is fixedly connected around the upper surface of the support platform 41. A first electric telescopic rod 68 is rotatably connected inside the first annular support 66 and the second annular support 67. One end of the first electric telescopic rod 68 passes through the first annular support 66 and is fixedly connected to a threaded rod 610. A partition plate 69 is fixedly connected to one end of the outer surface of the threaded rod 610. A bevel gear 611 is fixedly connected to the other end of the first electric telescopic rod 68. The bevel gear 611 meshes with the gear plate 52.

[0049] like Figures 1 to 9 As shown, the drive assembly also includes a threaded seat 612 rotatably connected to the outer circular surface of the threaded rod 610. A hinge frame 613 is fixedly connected to the top of the threaded seat 612. Slide plates 615 are fixedly connected to both sides of the outer surface of the hinge frame 613, and one side of the slide plate 615 is slidably connected to the U-shaped limiting groove 63. An adjusting plate 614 for supporting and adjusting the angle of the baffle 64 is hinged inside the hinge frame 613.

[0050] like Figures 1 to 9 As shown, the adjustment mechanism 5 also includes a gear ring 53 fixedly connected to the inner side of the bottom end of the annular plate 51. A second servo motor 54 is also fixedly installed on the upper surface of the base 1. A main gear 55 is fixedly connected to the top of the output shaft of the second servo motor 54. The main gear 55 meshes with the gear ring 53.

[0051] After the wheel hub to be processed is transported to the support platform 41 and placed on the upper surface of the sector frame 43, the first servo motor 47 is started to drive the cylindrical support platform 46 and the support platform 41 to rotate. At this time, the bevel gear 611 fixedly connected to the limit frame 61 rotates relative to and meshes with the stationary gear disk 52. The rotation of the bevel gear 611 drives the first electric telescopic rod 68 and the threaded rod 610 fixedly connected to it to rotate synchronously. The threaded rod 610 drives the threaded seat 612 on it to move along the rod body. Since the threaded seat 612 is slidably connected to the U-shaped limit grooves 63 on both sides of the inner wall of the limit frame 61 through the slide plate 615, its movement is restricted to linear movement. The movement of the threaded seat 612 is controlled by the hinge frame 613 and the adjustment mechanism hinged to it. Plate 614 pushes baffle 64, causing baffle 64 to rotate around the internal axis of the limiting frame 61. Multiple baffles 64 on the limiting frames 61 synchronously converge towards the center, clamping from the outer ring of the hub inwards, achieving automatic radial centering and clamping of the hub. During this process, the first electric telescopic rod 68 not only serves as a connecting component between the bevel gear 611 and the threaded rod 610, but also, when clamping hubs of different diameters, ensures that baffle 64 is in a vertical position. At this point, by stopping the movement of the first servo motor 47, the bevel gear 611 meshes with the gear plate 52 and maintains its position. Then, the first electric telescopic rod 68 is activated, causing the entire limiting frame 61, connecting baffle 64 and other components, to move towards the slider 62. Under the limiting action, the limiting frame 61 moves along the limiting groove 44 of the sector frame 43, thereby pushing the baffle 64 further toward the wheel hub to be processed, so as to complete the clamping work of wheel hubs of different diameters. When marking wheel hubs of the same size, without using the first electric telescopic rod 68 to change the position of the entire limiting frame 61, it is only necessary to use the external position marking sensor to determine whether the wheel hub has been moved to the designated marking position. When a spoke of the wheel hub just rotates and moves directly below the laser marking machine 11, the first servo motor 47 stops working. If the baffle 64 has not fully clamped the wheel hub, the second servo motor 54 is started, and the main gear 55 on its output shaft drives the wheel hub. The meshing gear ring 53 rotates, causing the fixedly connected annular plate 51 and the top gear disk 52 to rotate independently. The gear disk 52 then drives the bevel gear 611 to rotate, and through the aforementioned drive assembly, it continues to push the baffle 64 toward the center until the preset clamping force is reached, thus completing the precise clamping of the wheel hub. Throughout the process, through the coordinated cooperation of the rotating mechanism 4 and the adjusting mechanism 5, the centering mechanism 6 can automatically adjust the degree of convergence of the baffle 64 according to the wheel hub size without relying on manual intervention. This achieves rapid adaptive centering and clamping of wheel hubs of different specifications, effectively solving the problems of slow changeover and poor centering accuracy of traditional equipment, and significantly improving production efficiency and the consistency of marking quality.

[0052] like Figures 1 to 9As shown, a suction mechanism 8 for absorbing smoke is provided in the middle of the upper surface of the cylindrical support 46. The suction mechanism 8 includes a third electric telescopic rod 85 fixedly connected to the middle of the upper surface of the cylindrical support 46. A multi-hole suction head 86 is fixedly connected to the top of the third electric telescopic rod 85. A recycling tank 81 is fixedly connected to one side of the bottom of the support platform 41. An electric suction pump 82 is fixedly installed on the outer circular surface of the recycling tank 81. A first suction pipe 83 is connected between the electric suction pump 82 and the recycling tank 81. A second suction pipe 84 is fixedly connected to one output end of the electric suction pump 82. One end of the second suction pipe 84 passes through the cylindrical support 46 and is fixedly connected to the multi-hole suction head 86.

[0053] like Figures 1 to 9 As shown, an extension plate 45 is fixedly connected to the top edge of the fan-shaped frame 43; a second electric telescopic rod 7 is fixedly connected to the upper surface of the cylindrical support 46, and a U-shaped clamp 71 is fixedly connected to the top of the second electric telescopic rod 7.

[0054] To address the issues of uncollected fumes during laser marking, which pollute the processing environment and harm operator health, a third electric telescopic rod 85 is activated before laser marking begins. This extends the push rod at its top, raising the multi-hole suction head 86 to a suitable suction position near the bottom center of the wheel hub. The electric suction pump 82 then draws in the fumes generated during marking through the multi-hole suction head 86. The fumes are then transported to the recycling tank 81 after passing through the second suction pipe 84 and the first suction pipe 83. Centralized collection and storage are performed, with the entire suction process synchronized with laser marking. Because the multi-hole suction head 86 can be adjusted up and down with the No. 3 electric telescopic rod 85, it can adapt to the suction height requirements of different sized wheel hubs, effectively solving the problem of marking fume diffusion, improving the working environment, and ensuring the health and safety of operators. It also avoids the problem of fume adhering to the laser marking machine 11 lens and affecting the laser output quality, improving the stability of equipment operation and the clarity of the marking effect. Furthermore, during wheel hub marking, to further address the issue of circumferential dust remaining after radial clamping of the wheel hub... To address the issues of rotational clearance and difficulty in ensuring circumferential consistency of marking positions on each spoke, after the baffle 64 of the centering mechanism 6 clamps inward from the outer ring of the hub and completes radial centering, the second electric telescopic rod 7, fixedly connected to the upper surface of the cylindrical support 46, is activated. The push rod of the second electric telescopic rod 7 extends upward, causing the U-shaped clamp 71 at its top to rise. Since the U-shaped clamp 71 has been rotated to a preset angle along with the cylindrical support 46 before rising, its U-shaped opening precisely clamps both sides of a certain spoke of the hub, thus accurately defining the circumferential position of the hub and eliminating the problem of rotational clearance and difficulty in ensuring circumferential consistency of marking positions on each spoke. After the baffle 64 clamps the hub, there may be a slight rotational gap in the circumferential direction. At the same time, the extension plate 45 fixedly connected to the top edge of the fan-shaped frame 43 provides additional support and guidance for the hub, and assists the U-shaped clamp 71 to achieve more stable circumferential positioning. Through the above operations, the hub can further obtain circumferential anti-rotation positioning on the basis of radial clamping, which solves the problem of circumferential displacement of the hub due to external force interference or rotational inertia during the marking process. It ensures that the marking position height of each spoke on the circumference is consistent, effectively improving the positioning accuracy and product aesthetics of multi-spoke marking.

[0055] like Figures 1 to 9 As shown, the upper surface of the pallet 31 is also provided with a dust removal mechanism 12 for wiping the surface of the wheel hub to be processed. The dust removal mechanism 12 includes a column 121 fixedly connected to the upper surface of the pallet 31. A hydraulic rod 122 is fixedly connected to one side of the top of the column 121. A connecting block 123 is fixedly connected to one end of the hydraulic rod 122. A fourth electric telescopic rod 124 is fixedly connected to the bottom of the connecting block 123. A load-bearing plate 125 is fixedly connected to the bottom of the fourth electric telescopic rod 124. An infrared sensor 126 is fixedly installed at the bottom of the load-bearing plate 125. A spraying assembly is provided on one side of the outer surface of the load-bearing plate 125.

[0056] like Figures 1 to 9 As shown, the spraying assembly includes a water tank 127 fixedly connected to one side of the outer surface of the load-bearing plate 125. A fixing plate 1210 is fixedly connected to the bottom of the water tank 127, and a wiping cotton plate 1211 is fixedly connected to the bottom of the fixing plate 1210. A water pump 128 is fixedly installed on the front side of the water tank 127. One end of the water pump 128 is provided with a water pumping pipe fixedly connected to the water tank 127, and the other end is fixedly connected to an atomizing spray pipe 129.

[0057] like Figures 1 to 9 As shown, the atomizing nozzle 129 is fixedly installed on the load-bearing plate 125, and its nozzle is set towards the wiping cotton plate 1211.

[0058] To address the issue of dust, oil, or impurities potentially adhering to the surface of the wheel hub before it enters the marking station, leading to unclear markings, poor adhesion, or even broken or blurred lines during laser marking, the following procedure is implemented: Before laser marking begins, a hydraulic rod 122 is activated at the top of the column 121 fixedly connected to the upper surface of the support plate 31. The hydraulic rod 122 extends laterally, pushing a connecting block 123 fixedly connected at one end and a fourth electric telescopic rod 124 fixedly connected to the bottom of the connecting block 123 to move directly above the spokes of the wheel hub to be marked. Subsequently, the fourth electric telescopic rod... The rod 124 extends downwards, pushing the load-bearing plate 125 fixedly connected to its bottom end to descend. The infrared sensor 126 fixedly installed at the bottom of the load-bearing plate 125 detects the distance between itself and the wheel hub surface in real time. When it descends to the preset wiping height, the electric telescopic rod 124 stops descending. At this time, the water tank 127 fixedly connected to one side of the outer surface of the load-bearing plate 125 descends together with the load-bearing plate 125. Then, the water pump 128 is started, and cleaning fluid is drawn from the water tank 127 through the water pipe and delivered to the wiping cotton board 1, which is fixedly installed on the load-bearing plate 125 with the nozzle facing the wiping cotton board 1. The atomizing nozzle 129, installed at 211, evenly atomizes the cleaning liquid and sprays it onto the wiping cotton plate 1211, which is fixedly connected to the bottom of the fixing plate 1210. This keeps the wiping cotton plate 1211 appropriately moist. Then, the fourth electric telescopic rod 124 is activated again, causing the moistened wiping cotton plate 1211 to contact the wheel hub surface. This allows for relative friction between the moistened wiping cotton plate 1211 and the wheel hub surface during the subsequent rotation of the wheel hub using the rotating mechanism 4, effectively removing dust, oil, and impurities from the area of ​​the wheel hub to be marked. After cleaning, the No. 4 electric telescopic rod 124 and hydraulic rod 122 are reset in sequence, preparing for subsequent laser marking. Through the above operations, the dust removal mechanism 12 realizes automatic cleaning of the wheel hub surface, solving the problems of low efficiency and uneven cleaning of manual wiping, ensuring the cleanliness of the wheel hub surface before laser marking, thereby significantly improving the clarity, contrast and adhesion of the marking pattern. At the same time, the real-time distance detection of the infrared sensor 126 avoids excessive pressure between the wiping cotton board 1211 and the wheel hub surface, which could cause damage, thus improving the safety and reliability of the equipment.

[0059] In use, the invention first connects the entire device to a conveyor for transporting the wheel hub to be processed. The conveyor transports the wheel hub to be processed to the support platform 41 and places it on the upper surface of the sector frame 43. Then, the first servo motor 47 is started to drive the cylindrical support platform 46 and the support platform 41 to rotate. At this time, the bevel gear 611 fixedly connected to the limiting frame 61 rotates relative to and meshes with the stationary gear disk 52. Through the drive assembly, the baffle 64 is driven to converge and flip towards the center in the limiting frame 61, clamping from the outer ring of the wheel hub inward, realizing automatic radial centering and clamping of the wheel hub. During this process, when a certain spoke of the wheel hub... When the wheel hub is precisely rotated and moved directly below the laser marking device 11, the first servo motor 47 stops working. If the baffle 64 has not yet fully clamped the hub, the second servo motor 54 is activated, driving the gear ring 53 and gear disk 52 to rotate independently via the main gear 55. This drives the bevel gear 611 again, causing the baffle 64 to continue to converge towards the center until the preset clamping force is reached, thus completing the precise clamping of the hub. Subsequently, the second electric telescopic rod 7, which is fixedly connected to the upper surface of the cylindrical support 46, is activated, pushing the U-shaped clamp 71 upward so that its U-shaped opening precisely clamps both sides of one spoke of the hub, eliminating the small rotational gap of the hub in the circumferential direction and achieving circumferential clamping. First, the anti-rotation positioning is initiated. Then, the dust removal mechanism 12 is activated, and the load-bearing plate 125 and the wiping cotton plate 1211 are moved to above the spokes of the wheel hub to be marked via the hydraulic rod 122 and the fourth electric telescopic rod 124. The infrared sensor 126 detects the distance and controls the descent height. The water pump 128 sprays the cleaning fluid in the water tank 127 onto the wiping cotton plate 1211 through the atomizing nozzle 129. The rotating mechanism 4 drives the wheel hub to rotate, causing the wet wiping cotton plate 1211 to rub against the surface of the wheel hub, removing dust, oil, and impurities. After cleaning, all telescopic rods are reset. Then, the third electric telescopic rod 85 is activated to push the multi-hole suction... The head 86 rises to a suction position near the bottom center of the wheel hub, and the electric suction pump 82 is activated. The smoke and dust generated during the marking process are sucked into the collection tank 81 through the multi-hole suction head 86, the second suction pipe 84, and the first suction pipe 83 for centralized collection. Finally, the lifting platform 9 is activated and the laser marking device 11 is adjusted to a suitable marking height through the adjusting arm 10. The laser marking operation is performed on the wheel spokes. After the current wheel spoke is marked, the first servo motor 47 is activated again, so that the support platform 41 drives the wheel hub to rotate to the next wheel spoke, which is directly below the laser marking device 11. The above cleaning, vacuuming, and marking operations are repeated until all wheel spokes are marked.
