Description

Technical Field

[0001] This utility model relates to the field of mechanical engineering technology, and in particular to an automatic riveting equipment for elevator chain production. Background Technology

[0002] In modern elevator manufacturing plants, automated riveting equipment operates continuously and stably on large-scale elevator chain production lines, quickly and accurately riveting chain links to ensure that the strength and precision of each link meet the stringent safety requirements of high-rise and super high-rise buildings. Small elevator parts processing workshops, with their compact design, save space and flexibly handle customized orders. They ensure high efficiency in small-batch production while reducing reliance on skilled workers, allowing for easy switching between different elevator chain specifications.

[0003] The automated riveting equipment for elevator chains mainly achieves riveting through the coordinated operation of mechanical transmission and control systems. First, the elevator chain links are manually placed at the riveting station. Then, the punch in the riveting mechanism, driven by a hydraulic or pneumatic device, impacts the rivet at a set pressure and speed, deforming the rivet and tightly connecting the chain links, completing the riveting process. Afterwards, the riveted chain is manually moved so that the punch can proceed to the next riveting point. The entire process is efficient, precise, and stable.

[0004] In existing technologies, some automatic riveting equipment for elevator chains relies on manual feeding and material handling. However, manual material handling makes it difficult to ensure that the positional accuracy of each material handling is completely consistent. This can lead to deviations in the riveting position, resulting in weak connections between elevator chain links. This can cause uneven stress distribution between chain links, making them prone to loosening, accelerated wear, and other issues. Ultimately, this reduces the overall strength and reliability of the elevator chain, affecting product quality. Therefore, an automatic riveting equipment for elevator chain production is proposed to solve the above problems. Utility Model Content

[0043] Working principle: When riveting chain 18 and riveting rivet 19 need to be riveted, riveting chain 18 along with riveting rivet 19 is placed on the surface of conveyor belt 1. At this time, drive motor 2 starts, and the start of drive motor 2 drives rotating rod 3 to rotate. The rotation of rotating rod 3 drives rotating disk 4 to rotate. The rotation of rotating disk 4 causes rotating column 5 to drive sliding rod 23 to perform circular motion. The circular motion of sliding rod 23 causes the control plate 8 to move once through contact with control groove 6 with each rotation. Since the control plate 8 is fixedly connected to conveyor belt 1, each displacement of control plate 8 will cause conveyor belt 1 to drive riveting chain 18 to move once. Thus, after one riveting rivet 19 on riveting chain 18 is stamped and riveted by stamping table 17, it will move to the next place that needs to be riveted.

[0044] When the stamping table 17 rivets the riveting chain 18 inside the riveting rivet 19, it needs to be limited by the clamping assembly. At this time, the rotating motor 21 starts and drives the drive column 15 to rotate. The rotation of the drive column 15 drives the cam 13 to rotate. The rotation of the cam 13 drives the pressing rod 14 and the control rod 12 to move downward. The downward movement of the control rod 12 drives the vertical rod 10 to move downward. The downward movement of the vertical rod 10 drives the pressing plate 20 to move downward, thereby fixing the riveting chain 18. Then, when it is necessary to loosen the riveting chain 18, the rotating motor 21 drives the cam 13 to rotate again, thereby causing the return spring 16 to reset and push the control rod 12 up. This causes the control rod 12 to drive the vertical rod 10 and the pressing plate 20 to rise, thereby causing the pressing plate 20 to release the riveting chain 18.
