Description
Technical Field
[0001] The utility model relates to a leather positioning structure for leather covering of a steering wheel, belonging to the field of steering wheel processing. Background Art
[0002] In the automotive manufacturing and interior modification sectors, the steering wheel is a key component that drivers directly control. Its appearance, feel, and durability have a profound impact on the driving experience. As consumers' expectations for automotive interior quality continue to rise, leather steering wheel covering technology has become an important means of enhancing vehicle quality and driving comfort.
[0003] However, the commonly used steering wheel leather covering process has problems such as inaccurate positioning, complex installation, and inconvenient transportation, which seriously restrict production efficiency and product quality. Specifically, in traditional processes, leather is often fixed to the steering wheel by manual cutting and pasting. This process is not only time-consuming and labor-intensive, but also difficult to ensure that the leather fits perfectly with the surface of the steering wheel. It is prone to defects such as wrinkles and looseness, affecting the appearance and durability. In addition, due to the shape of the steering wheel, traditional positioning methods often find it difficult to achieve precise positioning of the leather, resulting in uneven covering effects and an inability to meet consumers' pursuit of high-quality interiors. At the same time, in the process of steering wheel leather covering, the handling and movement of the positioning structure is also a major problem. Traditional positioning structures are often bulky and heavy, and lack a convenient handling mechanism, which makes transfer and adjustment on the production line difficult, not only increasing labor costs, but also reducing production efficiency.

[0030] It should be noted that a support plate 7 is fixedly connected to the inner side of the center of the annular positioning frame 4 , a support rod 8 is fixedly connected to the inner side of the support plate 7 , and one end of the back of the support rod 8 is fixedly connected to the inner rear side wall of the mounting frame 3 .
[0031] The auxiliary component includes four elastic telescopic rods 9 fixedly connected to the inner side of the installation frame 3 and an arc-shaped positioning plate 10 fixedly connected to the ends of the piston rods of the elastic telescopic rods 9.
[0032] The four elastic telescopic rods 9 are respectively arranged on the inner top wall of the installation frame 3 , the inner bottom wall of the installation frame 3 , the inner left side wall of the installation frame 3 , and the inner right side wall of the installation frame 3 .
[0033] The top, bottom, left side wall and right side wall of the annular positioning frame 4 are all provided with movable openings adapted to the arc-shaped positioning plate 10 , and the movable openings are communicated with the positioning groove 5 .
[0034] The transport assembly includes a rotating rod 11 rotatably connected to the inner bottom wall of the base 1, a transmission gear 12 fixedly connected to the outside of the rotating rod 11, driven gears 13 respectively meshing with the left and right sides of the transmission gear 12, a threaded rod 14 fixedly connected to the inner side of the center of the driven gear 13, a threaded block 15 threadedly connected to the outside of the threaded rod 14, a connecting plate 16 respectively fixedly connected to the opposite side walls of the left and right threaded blocks 15, a mounting block 17 fixedly connected to the bottom of the connecting plate 16, and a plurality of balls 18 rotatably connected to the bottom of the mounting block 17. The bottom of the base 1 is provided with a plurality of through openings adapted to the balls 18.
[0035] Several ball grooves are provided at the bottom of the mounting block 17, and the balls 18 are rotatably connected to the bottom of the mounting block 17 through the corresponding ball grooves, and the several ball grooves on the same side are arranged in sequence along the front and rear directions of the mounting block 17. The opposite side walls of the left and right connecting plates 16 are fixedly connected to the guide blocks 19, and the inner side of the guide blocks 19 is slidably connected to the guide rods 20.
[0036] The working principle of the above embodiment is:
[0037] First, the leather is placed in the positioning groove 5 of the annular positioning frame 4. The adhesive layer 6 on the inner wall of the positioning groove 5 further enhances the adhesion between the leather and the positioning structure, so that the leather remains stable during subsequent processing. The annular positioning frame 4 is fixedly connected to the support rod 8 through the support plate 7, ensuring its stability in the installation frame 3, thereby indirectly ensuring the positioning accuracy of the leather. In addition, the top, bottom, left wall and right side wall of the annular positioning frame 4 are all provided with movable openings adapted to the arc-shaped positioning plates 10. These movable openings are not only connected to the positioning groove 5, but also allow the arc-shaped positioning plates 10 to further clamp and position the leather under the action of the elastic telescopic rod 9. When the piston rod of the elastic telescopic rod 9 is extended, the arc-shaped positioning plate 10 enters the positioning groove 5 through the movable opening, and is in close contact with the leather. Its arc-shaped design is used to better adapt to the curved surface of the leather, thereby achieving all-round stable positioning.
[0038] After the leather is positioned, the elastic telescopic rod 9 and the arc-shaped positioning plate 10 in the auxiliary assembly not only fix the leather, but also provide initial support and positioning for the steering wheel covering through their elastic adjustment capabilities. As the steering wheel is gradually installed, the elastic telescopic rod 9 can be fine-tuned according to the shape of the steering wheel, ensuring that the leather fits perfectly with the steering wheel surface, while reducing wrinkles or looseness caused by size differences or installation errors. This mechanism greatly improves the quality and efficiency of the steering wheel leather covering;
[0039] In order to facilitate the transportation and movement of the entire positioning structure, by rotating the rotating rod 11 connected to the inner bottom wall of the base 1, the transmission gear 12 can be driven to rotate, thereby driving the driven gears 13 on the left and right sides and the threaded rod 14 connected thereto to rotate synchronously. Since the outer side of the threaded rod 14 is threadedly connected to the threaded block 15, the rotation of the threaded rod 14 will be converted into linear motion of the threaded block 15. The threaded blocks 15 on the left and right sides are respectively connected to the mounting blocks 17 through the connecting plates 16. As the threaded blocks 15 move, the mounting blocks 17 and the balls 18 at their bottom also rise and fall accordingly. When the balls 18 extend through the through opening at the bottom of the base 1, they can roll freely, thereby greatly reducing the friction resistance of the positioning structure during movement and improving the convenience of transportation.
