Description

Technical Field

[0001] This utility model relates to the field of welding equipment technology, and more specifically, to a welding device for stainless steel kettle spouts. Background Technology

[0002] In the production process of stainless steel kettles, spout welding is a crucial step that determines product quality. For a long time, this step has relied heavily on manual labor, which has significant drawbacks that are difficult to overcome.

[0003] During manual positioning, the alignment of the spout and body for welding relies entirely on the operator's experience and manual operation. Due to the limited precision of human operation, minor deviations are unavoidable, directly resulting in irregularities in the appearance of the welded kettle and even affecting the normal function of the spout. This significantly increases rework and scrap costs due to inaccurate positioning, reducing the yield rate. During welding, manual operation with handheld welding tools leads to frequent hand tremors and variations in operating force. Welding quality depends entirely on the operator's skill and focus; products welded by different personnel, or even by the same person at different times, exhibit significant quality differences, making it difficult to meet standardized production requirements. Furthermore, manual welding is inefficient, unable to respond quickly to large-scale production orders, slowing down the overall production schedule and weakening the company's market competitiveness. Therefore, improvements are needed. Utility Model Content

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0020] like Figures 1 to 4 As shown, this utility model provides a welding device for stainless steel kettle spouts, comprising:

[0021] The top plate 1 has a base frame 29 fixedly installed at its bottom end. A lifting mechanism is provided on the left side of the top of the top plate 1. The lifting mechanism is composed of components such as cylinder 2, connecting block 3, and moving plate 4. A clamping mechanism is provided on the lifting mechanism. The clamping mechanism is composed of components such as fixed frame 8, power motor 9, and vertical shaft 10. A positioning mechanism is provided at the top of the top plate 1. The positioning mechanism is composed of components such as support rod 16 and arc block 17. A rotating mechanism is provided inside the top of the top of the top plate 1. The rotating mechanism is composed of components such as rotating ring 20, toothed ring 21, and rotating block 22. A driving mechanism is provided at the bottom of the top plate 1. The driving mechanism is composed of components such as driving motor 26 and short shaft 27.

[0022] The top plate 1, as the core load-bearing component, provides the installation foundation for components such as the cylinder 2 and the fixing frame 8. The base frame 29 fixed at its bottom ensures that the device is stably supported on the working plane, guaranteeing operational stability. The lifting mechanism consists of the cylinder 2, the connecting block 3, and the moving plate 4, used to realize the vertical displacement of the spout 7, so that the spout accurately approaches or moves away from the welding part of the stainless steel kettle body 18. The clamping mechanism includes the fixing frame 8, the power motor 9, and the vertical shaft 10, which can automatically clamp the spout to prevent displacement during welding. The positioning mechanism consists of the support rod 16 and the arc block 17. By the arc block fitting against the inner wall of the kettle and the positioning block 19 limiting the position, the stainless steel kettle body can be quickly and accurately positioned. The rotating mechanism and the driving mechanism work together. The driving motor 26 drives the welding head 25 to rotate around the welding part through gear transmission to complete the circular welding operation. All mechanisms cooperate with each other to realize the automation of the welding process.

[0023] The lifting mechanism includes a cylinder 2, the bottom end of which is fixedly connected to the left side of the top of the top plate 1. A connecting block 3 is fixedly sleeved at the output end of the cylinder 2. A moving plate 4 is fixedly installed at the right end of the connecting block 3. A vertical rod 5 is fixedly installed at the bottom end of the moving plate 4. A movable plate 6 is fixedly installed at the bottom end of the vertical rod 5. A spout 7 is movably sleeved inside the movable plate 6.

[0024] Cylinder 2 serves as the power source, and through the extension and retraction of its output end, it drives the connecting block 3 to move vertically, thereby causing the moving plate 4 to rise and fall synchronously. The vertical rod 5 and the movable plate 6 constitute a transmission assembly, which transmits the movement of the moving plate to the spout 7, ensuring that the spout can accurately descend to the welding position of the stainless steel kettle body 18 before welding.

[0025] The clamping mechanism includes a fixed frame 8, which is fixedly connected to the outer surface of the moving plate 4. A power motor 9 is fixedly installed at the top of the fixed frame 8. A vertical shaft 10 is fixedly sleeved at the output end of the power motor 9. A first gear 11 is fixedly sleeved on the outer surface of the vertical shaft 10. A second gear 12 is meshed on the outer surface of the first gear 11. A rotating shaft 13 is fixedly sleeved inside the second gear 12. An eccentric wheel 14 is fixedly sleeved at the bottom end of the rotating shaft 13. The outer surface of the eccentric wheel 14 is movably connected to the interior of the moving plate 6. A rubber ring 15 is fixedly sleeved on the outer surface of the eccentric wheel 14.

[0026] The fixing frame 8 is fixed on the motion plate 4 to provide installation support for the clamping assembly; the power motor 9 drives the vertical shaft 10 to rotate, and transmits the rotational motion to the rotating shaft 13 through the meshing of the first gear 11 and the second gear 12. At this time, the eccentric wheel 14 rotates with the rotating shaft 13. The radial displacement generated by its eccentric design drives the rubber ring 15 to squeeze the spout 7, thereby achieving adaptive clamping of the spout. The rubber ring 15 not only provides sufficient friction to prevent the spout from sliding, but also avoids damage to the spout surface caused by rigid contact, ensuring that the clamping process is stable and reliable.

[0027] The positioning mechanism includes a support rod 16, the bottom end of which is fixedly connected to the top end of the top plate 1. An arc-shaped block 17 is fixedly installed at the end of the support rod 16 away from the top plate 1. The outer surface of the arc-shaped block 17 is attached to the stainless steel kettle body 18. A positioning block 19 is fixedly installed on the outer surface of the arc-shaped block 17. The positioning block 19 is movably connected to the inner surface of the outer surface of the stainless steel kettle body 18.

[0028] The support rod 16 is fixed to the top of the top plate 1 to provide support for the arc-shaped block 17. The shape of the arc-shaped block matches the inner wall contour of the stainless steel kettle body 18, which can fit tightly against the kettle body and play a preliminary positioning role. The positioning block 19 protrudes from the surface of the arc-shaped block and is embedded in the inner surface of the outer surface of the stainless steel kettle body 18 to align the welded part of the stainless steel kettle body 18 with the spout 7, ensuring the consistency and accuracy of the welding position.

[0029] The rotating mechanism includes a rotating ring 20, which is movably connected to the top of the top plate 1. A toothed ring 21 is fixedly installed at the top of the rotating ring 20. A rotating block 22 is fixedly installed on the outer surface of the toothed ring 21. A long rod 23 is fixedly connected inside the rotating block 22. A hinge block 24 is fixedly installed at the top of the long rod 23. A welded head 25 is hinged inside the hinge block 24.

[0030] The rotating ring 20 can rotate freely inside the top of the top plate 1, providing rotational support for the rotating assembly; the toothed ring 21 is fixed to the top of the rotating ring. When the toothed ring 21 rotates under the drive of the rotating ring 20, the toothed ring 21 will drive the long rod 23 to rotate through the rotating block 22. Then the long rod 23 will drive the welding head 25 to rotate through the hinge block 24, so that the welding head makes a circular motion around the joint between the spout and the body. The hinge design of the hinge block allows the welding head to adjust the angle within a certain range to adapt to the welding requirements of different specifications.

[0031] The drive mechanism includes a drive motor 26, the top end of which is fixedly connected to the bottom end of the top plate 1. A short shaft 27 is fixedly sleeved on the output end of the drive motor 26, and a third gear 28 is fixedly sleeved on the outer surface of the short shaft 27. The third gear 28 meshes with the gear ring 21.

[0032] The drive motor 26 serves as the power core, driving the third gear 28 to rotate via the short shaft 27; the third gear 28 meshes with the gear ring 21, transmitting the rotational power of the motor to the rotating mechanism, driving the gear ring, rotating ring 20 and welding head 25 to rotate synchronously.

[0033] Working principle and usage process of this utility model:

[0034] When using this device, the operator first places the stainless steel kettle body 18 on the arc-shaped block 17. Utilizing the fit between the arc-shaped block 17 and the inner wall of the stainless steel kettle body, along with the precise positioning of the positioning block 19, the kettle body is quickly positioned, ensuring that the spout weld is precisely aligned with the movable plate 6. Then, the spout 7 is placed into the movable plate 6, aligning the bottom of the spout 7 with the welded part of the stainless steel kettle body 18 below it. Next, the power motor 9 is started. The output of the power motor 9 drives the vertical shaft 10 to rotate, which in turn drives the first gear 11, which is fixedly sleeved on the outer surface of the vertical shaft 10, to rotate. Since the outer surface of the first gear 11 meshes with the outer surfaces of the two second gears 12, the rotation of the first gear 11 drives the two second gears 12 to rotate. The two second gears 12 drive the eccentric wheel 14 to rotate through the rotating shaft 13. When the eccentric wheel 14 rotates, it drives the rubber ring 15, which is fixedly sleeved on its outer surface, to squeeze and push the outer surface of the spout 7, thereby fixing the spout 7.

[0035] After the spout 7 is fixed, start the cylinder 2. The output end of the cylinder 2 drives the connecting block 3 to move downward. The connecting block 3 drives the moving plate 4 to move downward as a whole. The moving plate 4 drives the movable plate 6 to move downward through the vertical rod 5, so that the bottom end of the spout 7 fits with the spout welding point on the stainless steel kettle body 18. Finally, the welding head 25 and the drive motor 26 are started simultaneously. When the drive motor 26 is running, the output end drives the short shaft 27 to rotate. The short shaft 27 drives the third gear 28, which is fixedly sleeved on its outer surface, to rotate. Since the outer surface of the third gear 28 is meshed with the gear ring 21, the rotation of the third gear 28 drives the gear ring 21 to rotate. The gear ring 21 drives the fixedly installed rotating ring 20 to rotate along the inside of the top of the top plate 1. At the same time, the gear ring 21 drives the rotating block 22 to rotate. The rotating block 22 drives the hinge block 24 to rotate through the long rod 23. The hinge block 24 drives the welding head 25 to rotate. During the rotation, the welding head 25 performs welding work on the joint between the spout 7 and the stainless steel kettle body 18, thereby completing the automatic welding process of the stainless steel kettle spout.
