With the wide application of laser cladding technology in the field of oil equipment manufacturing, laser cladding surface strengthening treatment is carried out on oil centralizer to improve its wear resistance, corrosion resistance and impact resistance and other performances become an important processing method.

[0003] At present, in the laser cladding processing of oil centralizer, rotating device is generally used to ensure the uniformity and integrity of laser cladding. The rotating device in prior art generally adopts simple mechanical structure, such as rotating shaft driven by motor and clamp connection, oil centralizer is fixed on clamp for rotation, and surface is processed by laser cladding equipment at the same time.

[0004] However, this traditional rotating device has certain limitations.

[0013] Furthermore, a control panel is provided on the outer wall of the console.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, through the ingenious cooperation of the centering component and the clamping component, centering and clamping of centralizers of different specifications can be achieved. In the centering component, by rotating the threaded rod, the extrusion block can slide in the elastic chuck, thereby adapting to centralizers of different inner diameters and achieving initial centering. For smaller centralizers, the centering component itself can provide stable clamping force, while for larger centralizers, the clamping component plays an important role. Under the synergistic action of the spring and the extrusion rod, the clamping block can closely fit the surface of the centralizer and work together with the centering component to ensure that the centralizer always maintains a precise center position during rotation. This design effectively avoids the problem of uneven laser cladding layer thickness caused by central offset of the centralizer, greatly improves the surface quality and performance of the centralizer, enhances its reliability and durability in actual use, and effectively meets the production requirements of high precision and high quality.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Reference Figure 1 , Figure 3 , Figure 4 and Figure 5This utility model provides an embodiment of a laser cladding rotating device for an oil stabilizer, comprising a control console 1, a disc 7 rotatably connected to the outer wall of the control console 1, a connecting plate 11 rotatably connected to the side of the disc 7 away from the control console 1, a centering component installed inside the connecting plate 11, a reinforcing component installed on the outer wall of the connecting plate 11, and multiple connecting blocks 12 fixedly connected to the outer wall of the connecting plate 11. Clamping components are installed inside the connecting blocks 12. The clamping components include a second fixing rod 18, the outer wall of which is fixedly connected to the inside of the connecting blocks 12. A clamping block 17 is rotatably connected to the outer wall of the second fixing rod 18, and a first fixing rod 15 is rotatably connected inside the clamping block 17. Rotating plates 16 are fixedly connected to the outer walls of both ends of the first fixing rod 15. A pressing rod 14 is rotatably connected to the outer wall of the first fixing rod 15. A spring 13 is fixedly connected to the end of the pressing rod 14 near the connecting plate 11, and the end of the spring 13 away from the pressing rod 14 is fixedly connected to the inner wall of the connecting plate 11. The clamping block 17 is slidably connected to the material 6 on the side near the disc 7; the reinforcing component includes an arc-shaped plate 8, the outer wall of which is fixedly connected to the outer wall of the connecting plate 11, and the side of the arc-shaped plate 8 away from the material 6 is rotatably connected to the side of the disc 7 near the connecting plate 11; the centering component includes a mounting sleeve 19, the end of which is rotatably connected to the side of the connecting plate 11 near the material 6, a threaded rod 20 is threadedly connected inside the connecting plate 11, the outer wall of the threaded rod 20 is threadedly connected to the inside of the mounting sleeve 19, a connecting rod 21 is fixedly connected to the end of the threaded rod 20 away from the connecting plate 11, and a pressing block 22 is fixedly connected to the end of the connecting rod 21 away from the threaded rod 20, an elastic clamp 10 is slidably connected to the outer wall of the pressing block 22, and the outer wall of the elastic clamp 10 is slidably connected to the inside of the material 6; the outer wall of the clamping block 17 is rotatably connected to the groove of the connecting block 12, and the inner wall of the rotating plate 16 is rotatably connected to the outer wall of the clamping block 17; a control panel 5 is provided on the outer wall of the control console 1.

[0026] Specifically, the entire device is controlled by a control console 1, whose outer wall is rotatably connected to a disc 7. This rotatable connection allows the disc 7 to rotate flexibly relative to the control console 1, providing a basis for the movement of subsequent components. The side of the disc 7 away from the control console 1 is rotatably connected to a connecting plate 11, allowing the connecting plate 11 to adjust its angle within a certain range. The centering component installed inside the connecting plate 11 plays a crucial role. One end of the mounting sleeve 19 in the centering component is rotatably connected to the side of the connecting plate 11 near the material 6, and its interior is threadedly connected to a threaded rod 20. The end of the threaded rod 20 away from the connecting plate 11 is fixedly connected to a connecting rod 21 and a pressing block 22 at the end of the connecting rod 21. By rotating the threaded rod 20, the pressing block 22 slides within the elastic clamp 10, thereby adapting to materials 6 with different inner diameters and achieving a preliminary centering function, ensuring a tight fit against the inner wall of the material 6 and providing stable centering and clamping force. The reinforcing component installed on the outer wall of the connecting plate 11 has an arc-shaped plate 8 whose outer wall is fixed to the connecting plate 11. The side furthest from the material 6 is rotatably connected to the disc 7. This structure enhances the connection between the three protruding parts of the connecting plate 11, improving its stability and reducing the possibility of shaking and displacement. Multiple connecting blocks 12 on the outer wall of the connecting plate 11 are equipped with clamping components. The fixing rod 18 in the clamping components is fixed inside the connecting block 12. The clamping block 17 is rotatably connected to the fixing rod 18. The rotating plates 16 at both ends of the fixing rod 15 and the pressing rod 14 rotatably connected to the fixing rod 15 inside the clamping block 17, together with the elastic action of the spring 13, allow the clamping block 17 to fit tightly against the surface of the material 6. For example, when processing larger material 6, the elastic force of the spring 13 is transmitted to the clamping block 17 through the pressing rod 14, causing the clamping block 17 to rotate on the fixing rod 18 and press the material 6. Together with the centering component, it ensures that the material 6 always maintains a precise center position during rotation. The control panel 5 on the outer wall of the control console 1 allows the operator to control the device and adjust the parameters, making the entire laser cladding process more convenient and efficient.

[0027] Reference Figure 1 and Figure 2 A base 3 is fixedly connected to the lower surface of the control console 1. A guide rail 4 is fixedly connected to the upper surface of the base 3. A spindle box 2 is slidably connected to the outer wall of the guide rail 4. A connecting plate 26 is fixedly connected to the lower part of the spindle box 2 near the material 6. A support rod 25 is fixedly connected to the upper surface of the connecting plate 26. A mounting plate 24 is fixedly connected to the end of the support rod 25 away from the connecting plate 26. A fixing rod 23 is fixedly connected inside the mounting plate 24. A cleaning roller 27 is rotatably connected to the outer wall of the fixing rod 23. A chassis 9 is fixedly connected to the upper surface of the guide rail 4. The spindle box 2 is slidably connected to the outer wall of the chassis 9. The lower surface of the connecting plate 26 is slidably connected to the upper surface of the chassis 9. The end of the material 6 away from the disc 7 is rotatably connected inside the spindle box 2.

[0028] Specifically, the base 3, fixedly connected to the lower surface of the control console 1, provides stable support for the entire device. The guide rail 4 on the upper surface of the base 3 is slidably connected to the spindle box 2. At the same time, the chassis 9 on the upper surface of the guide rail 4 is also slidably connected to the spindle box 2. Furthermore, the lower surface of the connecting plate 26 on the side of the spindle box 2 closest to the material 6 is slidably connected to the upper surface of the chassis 9. This multi-sliding connection method allows the spindle box 2 to be precisely positioned and adjusted in the horizontal direction to adapt to different processing requirements. The connecting plate 26 installed on the outer wall of the spindle box 2 is connected to the mounting plate 24 through the support rod 25. The fixing rod 23 fixed inside the mounting plate 24 is rotatably connected to the cleaning roller 27. During the laser cladding process... During the process, as material 6 rotates, cleaning roller 27 can contact the surface of material 6 in real time, effectively removing any oil or other contaminants that may be present on the surface of material 6. For example, if there is oil on the surface of material 6 before processing, the cleaning roller 27 will wipe the oil clean as material 6 rotates, providing a clean surface condition for subsequent laser cladding operations, ensuring good bonding between the cladding layer and the substrate of material 6, improving cladding quality, reducing waste caused by impurities, increasing production efficiency, reducing costs, and extending the service life of the laser cladding equipment. The end of material 6 away from the disc 7 is rotatably connected to the inside of the spindle box 2, further ensuring the stability and smooth rotation of material 6 during processing.

[0029] Working Principle: The operator first places material 6 (oil stabilizer) on the device. For different specifications of material 6, preliminary adjustment is made through the centering component. Specifically, rotating the connecting plate 11 drives the threaded rod 20 in the centering component to rotate, allowing it to move inside the mounting sleeve 19. This causes the connecting rod 21 to drive the extrusion block 22 to slide within the elastic clamp 10. The gradually narrowing path of the elastic clamp 10 allows it to spread outwards, thus adapting to the inner diameter of material 6 and achieving preliminary centering. If the material 6 is small, the centering component itself can provide sufficient clamping force to ensure the stability of material 6. If the material 6 is large, the clamping component begins to play an important role, using the material 6 to clamp the block. The clamping block 17 is pressed down to rotate within the groove of the connecting block 12. When the clamping block 17 presses downwards, the rotating plate 16 rotates, thus converting the pressure generated by the rotation of the clamping block 17 into an inward pressing force. This causes the pressing rod 14 to press against the spring 13. When the material 6 slides to the inner wall of the clamping block 17, the clamping block 17 loses pressure. At this time, the spring 13 returns to its original state due to the loss of pressure, causing the pressing rod 14 to move outwards. This allows the clamping block 17 to return to its original position, thus securing the material 6 against the inner wall of the clamping block 17. This achieves the clamping of the material 6. Through the combined action of the clamping component and the centering component, the material 6 maintains a precise center position throughout the rotation process, completing the material clamping process. 6. After installation and centering clamping, the operator starts the device through the control panel 5 on the outer wall of the console 1. The console 1, as the core control part, coordinates the work of various components. The spindle box 2 slides on the guide rail 4 on the upper surface of the base 3 and on the chassis 9, adjusting to the appropriate position according to processing requirements to ensure the accuracy of laser cladding operation. The end of the material 6 away from the disc 7 rotates and connects inside the spindle box 2, ensuring the stability and smoothness of the rotation of the material 6. During the rotation of the material 6, the cleaning roller 27 located below the material 6 starts to work. Since the cleaning roller 27 is rotatably connected to the mounting plate 24 through the fixing rod 3 23, and the mounting plate 24 is connected to the connecting plate 26 on the spindle box 2 through the support rod 25, when the material 6... During rotation, the cleaning roller 27 can contact the surface of the material 6 in real time to remove any oil or other contaminants that may be present on the surface of the material 6. If there is oil on the surface of the material 6 before processing, the cleaning roller 27 will wipe the oil clean as the material 6 rotates, providing a clean surface condition for subsequent laser cladding operations. This effectively ensures a good bond between the cladding layer and the substrate of the material 6, improves cladding quality, reduces waste caused by impurities, increases production efficiency, reduces costs, and extends the service life of the laser cladding equipment. Throughout the entire processing, all components work together to ensure that the oil centralizer achieves efficient and high-quality processing during the laser cladding process, ultimately resulting in a high-performance laser-clad strengthened oil centralizer product.
