Description

Technical Field

[0001] This utility model relates to the field of spring welding technology, specifically to a spring welding device. Background Technology

[0002] A spring is a mechanical part made of an elastic material that works by utilizing its ability to deform and return to its original shape. It is commonly made of spring steel and comes in various types, categorized by shape as helical springs, spiral springs, leaf springs, and irregularly shaped springs. During processing and use, the spring and the steel plate need to be welded together.

[0003] During the welding process of springs, the lack of a limiting device makes it impossible to ensure that the spring and the steel plate remain perpendicular, resulting in a difference in the included angle between the welded spring and the steel plate, which affects the subsequent use of the spring. Therefore, it is necessary to design a spring welding device to assist in the welding of springs and steel plates and improve the above problems. Utility Model Content

[0024] In the following description, embodiments of the spring welding device of the present invention will be described with reference to the accompanying drawings.

[0025] Figure 1-3 This invention illustrates a spring welding apparatus according to an embodiment of the present invention, comprising:

[0026] The system comprises an operating table 1, a steel plate body 7, and a spring body 8. A rotating table 2 is rotatably connected to the top of the operating table 1. The steel plate body 7 is placed on the top of the rotating table 2. Specifically, a rotating handle 21 is fixedly installed on the outer surface of the rotating table 2. The size of the rotating table 2 can be larger and wider to accommodate the use of steel plate bodies 7 of different sizes. If necessary, when the shape of the steel plate body 7 is irregular, a support block or clamp that works with the steel plate body 7 can be set on the top of the rotating table 2 to keep the welded joint of the steel plate body 7 parallel to the rotating table 2, which facilitates subsequent welding operations.

[0027] A vertical rod 3 is fixedly installed on the top of the rotating platform 2. A lifting rod 4 is slidably connected to the front side of the vertical rod 3. Specifically, a threaded rod 9 extending to the outside is rotatably connected to the inner cavity of the vertical rod 3. The end of the lifting rod 4 near the vertical rod 3 extends into the inner cavity of the vertical rod 3 and is threadedly connected to the surface of the threaded rod 9. A handwheel 10 is fixedly installed on the top of the threaded rod 9. A spring inner support vertical assembly 5 is provided at the bottom of the lifting rod 4. The spring body 8 is sleeved and locked on the surface of the spring inner support vertical assembly 5. Through the setting of the spring inner support vertical assembly 5, spring bodies 8 of different sizes can be clamped and locked, thereby realizing the welding operation of spring bodies 8 of different sizes and improving the practicality of the welding device. Specifically, the spring inner support vertical assembly 5 includes a vertical rod 51 detachably installed at the bottom of the lifting rod 4. Specifically, a limit piece 511 is welded to the upper end of the vertical rod 51, and a locking nut 512 is threadedly connected to the top of the vertical rod 51. The lifting rod 4 is clamped between the limit piece 511 and the locking nut 512. The installation of the stop nut 512 allows for the disassembly of the spring inner support vertical assembly 5 and the lifting rod 4, facilitating the replacement and maintenance of the spring inner support vertical assembly 5. A base column 52 is welded to the bottom of the vertical rod 51. Three inner support arc-shaped plates 53 are slidably connected to the outer side of the base column 52. The inner support arc-shaped plates 53 are arranged in a circular array on the surface of the base column 52. Flexible pads 54 are adhered to the opposite sides of each inner support arc-shaped plate 53. The spring body 8 is sleeved on the surface of the flexible pads 54. Specifically, the inner sides of the inner support arc-shaped plates 53 are rotatably connected... There are two rotating rods 55, and the opposite sides of the rotating rods 55 are rotatably connected to the surface of the base column 52. The surface of the vertical rod 51 is slidably connected to the sliding sleeve 57. The surface of the sliding sleeve 57 is rotatably connected to three rotating rods 56. The opposite ends of the rotating rods 56 are rotatably connected to the surface of the inner support arc plate 53. Specifically, the surface of the vertical rod 51 is rotatably connected to the rotating sleeve 58. The sliding sleeve 57 is threadedly connected to the surface of the rotating sleeve 58. The upper end of the surface of the rotating sleeve 58 is bonded with an anti-slip sleeve 581.

[0028] It also includes a cold welding machine 6, which is installed on top of the operating table 1;

[0029] When locking the spring body 8 internally, care should be taken to ensure that the flexible pad 54 is kept at a certain distance from the bottom of the spring body 8 to avoid damage to the flexible pad 54 during welding.

[0030] Working principle: When using this utility model, the user places the spring body 8 from the bottom of the spring inner support vertical assembly 5 onto the surface of the vertical rod 51. Then, rotating the anti-slip sleeve 581 causes the rotating sleeve 58 to rotate on the surface of the vertical rod 51, thereby causing the sliding sleeve 57 to slide downward on the surface of the rotating sleeve 58. This, in turn, causes the rotating rod 2 56 to rotate and pushes the three inner support arc plates 53 to slide synchronously in opposite directions. At this time, the rotating rod 1 55 will rotate synchronously, causing the three flexible pads 54 to slide in opposite directions and lock the spring body 8 inward. At this time, the spring body 8 and the vertical rod 51 remain coaxial and are aligned with the rotating platform 2. The spring body 8 is positioned vertically. Then, the handwheel 10 is turned to rotate the threaded rod 9 within the inner cavity of the upright 3, thereby causing the lifting rod 4 and the spring inner support vertical assembly 5 to slide towards each other until the bottom of the spring body 8 contacts the steel plate body 7 at the top of the rotating platform 2. After that, the position of the steel plate body 7 is adjusted so that the spring body 8 is at the welding point. The contact point between the spring body 8 and the steel plate body 7 is welded using a cold welding machine 6. The rotating platform 2 is rotated by holding the rotating handle 21, causing the spring body 8 and the steel plate body 7 to rotate synchronously. While rotating, the spring body 8 is fully welded, which greatly improves the welding quality and efficiency.

[0031] In summary, this spring welding device uses the spring inner support vertical component 5 to internally support and lock the spring body 8, keeping the spring body 8 and the steel plate body 7 perpendicular. Then, the cold welding machine 6 is used to weld the contact area between the spring body 8 and the steel plate body 7, and the rotating table 2 is rotated to complete the full welding of the spring body 8, which greatly improves the welding quality and efficiency.

[0032] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
