[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0022] Reference Figure 1-5 A spot welding device for jewelry processing includes a frame 1. A hydraulic cylinder 2 is bolted to one side of the top of the frame 1. A support plate 3 is provided on the upper inner side of the frame 1, serving as a carrier for a laser welding device 4. The support plate 3 moves vertically under the action of the hydraulic cylinder 2, ensuring that the laser welding device 4 can accurately reach the designated welding position. The laser welding device 4 is mounted on the bottom of the support plate 3. The output shaft of the hydraulic cylinder 2 passes through the top of the frame 1 and is fixedly connected to the top of the support plate 3. A slider 12 is slidably connected to the bottom inner side of the frame 1. The slider 12 allows the support plate 5 to be adjusted horizontally, facilitating the adjustment of the position of the jewelry material. The top of the device is rotatably connected to a support plate 5. The support plate 5 can be adjusted laterally and angularly with the support of the slider 12, which facilitates the precise positioning of jewelry of different shapes and sizes. The top of the support plate 5 is provided with an annular groove 6. The top of the support plate 5 is fixedly connected to an outer tube 7, and the inner side of the outer tube 7 is elastically connected to an inner rod 8. Several side plates 9 are fixedly connected to the top of the inner rod 8, and the bottom of all the side plates 9 is fixedly connected to a limiting plate 11. The limiting plate 11 is connected to the side plate 9 through a support rod 10, which ensures sufficient support force. At the same time, the elasticity between the inner rod 8 and the outer tube 7 is used to fix the jewelry material firmly and gently. All the limiting plates 11 are located at the top of the annular groove 6.

[0023] When operating a spot welding device for jewelry processing, the jewelry material to be spot welded is first placed inside the annular groove 6 of the support plate 5. The elastic connection between the inner rod 8 and the outer tube 7 allows the limiting plate 11 to exert a certain elastic compressive force on the material, ensuring it is securely fixed without affecting the welding area. Subsequently, the support plate 5 can be moved left and right as needed via the slider 12 to adjust the material laterally. Simultaneously, the support plate 5 can also be rotated to adjust the welding angle or position. Once all preparations are complete, the laser welding equipment 4 is started, and the support plate 3 is driven downwards by the hydraulic cylinder 2, allowing the laser welding equipment 4 to precisely align and process the designated welding points on the material.

[0024] Furthermore, the slider 12 is slidably connected to the inner bottom of the frame 1 via the slide groove 13. A cylinder 14 is fixedly connected to one side of the outer wall of the frame 1 by bolts, and the output shaft of the cylinder 14 passes through the side wall of the frame 1 and is fixedly connected to one side of the slider 12. The output shaft of the cylinder 14 pushes the slider 12 to slide horizontally in the slide groove 13, thereby realizing the lateral adjustment of the bearing plate 5. This achieves the effect of precisely controlling the position of the bearing plate 5, ensuring that the jewelry material can be quickly and accurately adjusted to the required welding point in the horizontal direction, further improving the flexibility and efficiency of operation.

[0025] Furthermore, the bottom end of the inner rod 8 is elastically connected to the inner bottom of the outer tube 7 via a tension spring 15. The tension spring 15 provides elastic support for the inner rod 8, enabling the limiting plate 11 to apply a moderate compressive force to the jewelry material placed in the annular groove 6.

[0026] Furthermore, the top of all the limiting plates 11 is fixedly connected to the bottom of all the side plates 9 by the support rods 10.

[0027] Furthermore, the connection between the output shaft of cylinder 14 and the output shaft of hydraulic cylinder 2 and the frame 1 is a sliding connection. The support rod 10 connects the side plate 9 and the limiting plate 11 into an integral structure, which enhances the stability of the limiting plate 11.

[0028] Furthermore, the slider 12 and the groove 13 are fitted with a clearance.

[0029] In summary:

[0030] First, the jewelry material to be spot-welded is placed inside the annular groove 6 of the support plate 5. The elastic connection between the inner rod 8 and the outer tube 7 allows the limiting plate 11 to exert a certain elastic compressive force on the material, ensuring it is firmly fixed without affecting the welding point. Then, as needed, the support plate 5 can be moved left and right by the slider 12 to adjust the material laterally. Simultaneously, the support plate 5 can also be rotated to adjust the welding angle or position. Notably, the slider 12 is slidably connected to the inner bottom of the frame 1 via a groove 13, and is pushed horizontally within the groove 13 by the output shaft of the cylinder 14. This allows for precise lateral adjustment of the support plate 5, ensuring the jewelry material can be quickly and accurately adjusted to the desired welding point in the horizontal direction, further improving operational flexibility and efficiency. Furthermore, the bottom end of the inner rod 8 is elastically connected to the inner bottom of the outer tube 7 via a tension spring 15. The tension spring 15 provides elastic support for the inner rod 8, allowing the limiting plate 11 to apply moderate compressive force to the jewelry material placed in the annular groove 6, thus securing the material firmly while preventing damage. The tops of all the limiting plates 11 are fixedly connected to the bottoms of all the side plates 9 via support rods 10. The support rods 10 connect the side plates 9 and the limiting plates 11 into a single structure, enhancing the stability of the limiting plates 11 and preventing welding deviations caused by material movement, thereby improving welding accuracy and finished product quality. Once all preparations are complete, the laser welding equipment 4 is started, and the bearing plate 3 is driven downward by the hydraulic cylinder 2, enabling the laser welding equipment 4 to accurately align and process the designated welding points on the material. It is worth noting that the output shafts of the cylinder 14 and the hydraulic cylinder 2 are slidably connected to the frame 1. This design ensures the independence and stability of their respective movements, optimizes the overall operating performance of the equipment, and makes the device more coordinated and reliable during multi-directional adjustment and welding processes. Finally, the clearance fit between slider 12 and groove 13 reduces frictional resistance, ensuring the stability and accuracy of slider 12 during movement, reducing equipment wear and extending service life. It also improves the smoothness of lateral adjustment and positioning accuracy of bearing plate 5, providing strong support for efficient and high-quality jewelry processing.The precise control and flexible adjustment of the bearing plate 5 are achieved through the arrangement of slider 12, slide groove 13, and cylinder 14, greatly improving the adjustment speed and accuracy of jewelry materials in the horizontal direction, and enhancing operational flexibility and efficiency. The elastic connection between the inner rod 8 and the tension spring 15 achieves a stable fixation of the material while preventing damage, making it suitable for handling complex or fragile jewelry materials, thus improving the safety and applicability of the device. The support rod 10 connects the side plate 9 and the limiting plate 11 into an integral structure, enhancing the stability of the limiting plate 11, effectively preventing welding deviations caused by material movement, and improving welding quality and product consistency. The sliding connection design between the output shaft of cylinder 14 and the output shaft of hydraulic cylinder 2 and the frame 1 optimizes the overall operating performance of the equipment, making multi-directional adjustment and welding processes smoother and more reliable. The clearance fit between slider 12 and slide groove 13 reduces equipment wear, extends service life, and improves the smoothness and positioning accuracy of the lateral adjustment of the bearing plate 5, providing a solid guarantee for high-quality jewelry processing.
