[0019] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer and more understandable, 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 only used to explain this utility model and are not intended to limit this utility model.

[0020] This application provides a pneumatic riveting device for brake pads in mining vehicles, aiming to solve problems such as inaccurate positioning of brake shoes and friction linings, poor riveting quality, and low production efficiency in traditional manual riveting processes. This device combines pneumatic and hydraulic systems, providing efficient and accurate riveting capabilities, while also being compact, easy to operate, and easy to maintain.

[0021] like Figure 1 As shown, in this embodiment, the core components of the device include a worktable 1, a riveting mechanism 2, a rotating assembly 3, and a positioning assembly 4. A riveting mechanism 2 for riveting is disposed above the worktable 1. The riveting mechanism 2 consists of a first cylinder 21 and a second cylinder 22, which are horizontally fixed. A first punch 211 and a second punch 221 are respectively mounted on the upper end of each cylinder. During riveting, the punches accurately press the rivets into the riveting holes of the brake shoes and friction linings, thereby completing the riveting task. The arrangement of the first cylinder 21 and the second cylinder 22 ensures that the punches maintain a stable force during the riveting process, improving riveting accuracy and avoiding riveting errors caused by punch instability. Furthermore, the first cylinder 21 and the second cylinder 22 are impact cylinders.

[0022] like Figure 2 and Figure 3As shown, to ensure accurate positioning of the brake shoe and friction lining during riveting, this embodiment includes a rotating assembly 3 on the worktable 1. The rotating assembly 3 allows the brake shoe and friction lining to rotate at a fixed angle, ensuring accurate alignment of the riveting holes on the brake shoe and friction lining with the punch, thus avoiding errors caused by manual adjustment in traditional manual operations. The rotating assembly 3 includes a fixed disk 31 and a rotating disk 33 fixedly mounted on the worktable 1. A rotating shaft 32 extends upward from the fixed disk 31 and rotates the rotating disk 33 via a bearing 6. The brake shoe and friction lining are placed on top of the rotating disk 33. A positioning assembly 4 is provided between the fixed disk 31 and the rotating disk 33. The positioning assembly 4 ensures precise positioning of the rotating disk 33 during rotation and stabilizes its position after riveting, guaranteeing the accuracy of each riveting operation.

[0023] like Figure 1 , Figure 3 and Figure 4 As shown, the positioning component 4 is designed to ensure riveting accuracy. This positioning component 4 includes a fixing rod 41 hinged to the outer edge of the rotating disk 33. The fixing rod 41 consists of a cylindrical rod 411 and a ball 412. Multiple recessed blocks 42 are arranged in an array with the same circumferential angle on the fixing disk 31 for engaging the fixing rod 41. Thus, the cooperation between the fixing rod 41 and the recessed blocks 42 ensures stable positioning of the rotating disk 33 during rotation, avoiding riveting errors caused by unstable rotation of the brake shoes and friction linings. The inner surface of each recessed block 42 can be provided with a magnetic attractant 8 as needed to enhance the attraction of the ball 412 on the fixing rod 41, thereby improving positioning stability.

[0024] like Figure 3 As shown, in order to accommodate different types of brake shoes and friction linings with riveting hole arrays, this application designs a detachable ring sleeve 5. A groove block 42 is fixedly provided on the ring sleeve 5, and the ring sleeve 5 can be replaced according to actual needs. By replacing different ring sleeves 5, users can easily adapt to different specifications of riveting hole arrays, avoiding the problem of frequently replacing the entire device required by traditional riveting devices, thus improving the adaptability and flexibility of the equipment.

[0025] Furthermore, the bearing 6 installed on the rotating shaft 32 reduces frictional resistance, ensuring smooth operation of the rotating disk 33 during rotation and further improving riveting accuracy. The use of bearing 6 also reduces equipment wear caused by excessive friction, thereby extending the service life of the equipment.

[0026] like Figure 3As shown, to ensure that the brake shoe and friction lining do not shift during the riveting process, the rotating assembly 3 is also provided with a positioning slot 7 for stably placing the brake shoe. The positioning slot 7 is fixedly mounted on the rotating disk 33, and usually includes two, which respectively fix and limit the two ends of the brake shoe. This design allows the brake shoe and friction lining to be stably maintained in a predetermined position during rotation, avoiding riveting deviations caused by displacement.

[0027] The pneumatic riveting device for mining vehicle brake pads disclosed in this application, through reasonable design and coordination, can effectively improve riveting accuracy, reduce human error, and increase production efficiency. Compared with traditional manual riveting methods, this application, through an automated pneumatic and hydraulic system, not only improves production efficiency but also significantly enhances product consistency and reliability. Furthermore, the device is flexible, adaptable, and maintainable, accommodating different models and specifications of brake pads and brake shoes. Its compact structure and ease of operation greatly reduce the complexity and cost of the production line.

[0028] In summary, this application, through innovative design and reasonable technical solutions, solves the problems of low riveting accuracy, poor production efficiency, and poor equipment adaptability of existing technologies for brake shoes and friction linings, and has good technical advantages and broad application prospects.

[0029] The present invention has been described above with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution to other situations without modification, are all within the protection scope of the present invention.
