Technical Field
[0001] This utility model relates to the field of automated production equipment technology, and more specifically, to a variable cross-section steel leaf spring assembly device. Background Technology
[0002] In the wave of rapid development in transportation and mechanical engineering, variable cross-section leaf springs have emerged. In the past, traditional constant cross-section leaf springs dominated the market. However, as vehicles move towards high speed, heavy load, and lightweight design, their drawbacks have become increasingly apparent. On the one hand, constant cross-section design easily leads to material waste, increases vehicle weight, and is not conducive to energy conservation. On the other hand, it is difficult to balance load-bearing capacity and comfort under complex working conditions. Variable cross-section leaf springs have emerged to address this issue. They flexibly change the cross-sectional shape according to the stress characteristics, optimize stress distribution, and significantly reduce weight while maintaining the same strength. This not only meets the demand for vehicle lightweighting but also ensures smooth driving, opening a new chapter in automobiles, trailers, construction machinery, and other fields.
[0003] The current assembly of variable cross-section leaf springs faces numerous challenges. Due to the complex structure of variable cross-section leaf springs, their unique gradient cross-section shape, and the need for precise dimensional tolerances, the assembly process is fraught with difficulties. Many key steps, such as the precise stacking of multiple springs and the installation of special connectors, are difficult to complete manually. Manual operation is not only inefficient but also prone to errors due to fatigue and visual biases, leading to poor product consistency and unstable quality. Furthermore, operations in confined spaces are impossible for manual labor. These limitations severely hinder the smooth progress of the assembly process, thus requiring improvement and optimization. Utility Model Content
[0004] In order to overcome the shortcomings of the existing technology, this utility model provides a variable cross-section steel leaf spring assembly device, which has the advantage of improving assembly efficiency.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a variable cross-section steel leaf spring assembly device, comprising a fixed bracket and a base plate. The fixed bracket internally houses a clamping mechanism, a spring-pushing mechanism, and a bidirectional moving mechanism. The clamping mechanism includes a support frame fixedly installed inside the fixed bracket. A hydraulic cylinder is fixedly installed on the inner side of the support frame. A connecting plate is fixedly installed at the output end of the hydraulic cylinder. A first pressing block is fixedly installed on the bottom side of the connecting plate. The spring-pushing mechanism includes a first fixed base fixedly installed inside the fixed bracket. A slide rail is fixedly installed on the top of the first fixed base.

A cylinder 8 is fixedly installed on the top of the first fixed base 7, and the slide rail 9 is located below the cylinder 8. A linkage block 10 is fixedly installed at the output end of the cylinder 8 and is linked... Block 10 is slidably mounted on the outer surface of slide rail 9. A first positioning block 11 is fixedly mounted on the top of linkage block 10. A fixed platform 20 is fixedly mounted on the top of first fixed base 7. The bidirectional moving mechanism includes a second fixed base 16 fixedly mounted inside fixed bracket 1. A first moving cylinder 17 is fixedly mounted inside the second fixed base 16, and the output end of the first moving cylinder 17 extends out of the second fixed base 16.

The output end of the second moving cylinder 18 drives the second pressing block 19 to lift the spring 15 and push the spring 15 into the bearing plate 12. Then, the first moving cylinder 17 drives the second moving cylinder 18 to descend and push the spring into the bearing plate 12 in sequence. At this time, the cylinder 8 is activated, and the output end of the cylinder 8 will slide on the slide rail 9 against the linkage block 10. At the same time, the first positioning block 11 will push the spring 15 in the opposite direction and the second pressing block 19 will push the spring 15 in the forward direction, so that the spring 15 is correctly installed into the bearing plate 12. At this time, the rivet 13 and the buffer pad 14 are placed on the bearing plate 12. Then, the hydraulic cylinder 4 is activated, so that the output end of the hydraulic cylinder 4 drives the connecting plate 5 and the first pressing block 6 downward to press the rivet 13, the buffer pad 14 and the spring 15.

Then, the hydraulic cylinder 4 is activated, causing the output end of the hydraulic cylinder 4 to drive the connecting plate 5 and the first pressing block 6 downward to press the rivet 13, the buffer pad 14 and the spring 15. Compared with traditional devices, this device can effectively make up for the limitations of manual operation by automating the assembly process. The precise operation of the equipment not only greatly improves the assembly efficiency, but also perfectly guarantees the consistency and integrity of the products, ensuring that every product meets high quality standards.

Then, the camera 25 automatically takes pictures to identify the carrier plate 12 of the assembly product. The picture taken by the camera 25 will be displayed on the display case 21. The display case 21 is electrically connected to the button 22, the electric rail 23 and the camera 25. Compared with the traditional device, this device adds a small light source under the carrier plate 12, which can clearly identify the bright area without the buffer pad, thus avoiding the overall black screen when there is no buffer pad.
[0023] The top of the fixed platform 20 is fixedly installed with a plastic block 30, and the plastic block 30 extends out of the bearing plate 12.

The output end of the second moving cylinder 18 drives the second pressing block 19 to lift the spring 15 and push the spring 15 into the bearing plate 12. Then, the first moving cylinder 17 drives the second moving cylinder 18 to descend and push the spring into the bearing plate 12 in sequence. At this time, the cylinder 8 is activated, and the output end of the cylinder 8 will slide on the slide rail 9 against the linkage block 10.
