However, as the industry shifts towards multi-model mixed-line production, this traditional structure is gradually revealing its limitations. Specifically, the fixed stroke and limited adjustability of the pneumatic telescopic forks cannot adapt to the diverse needs of different vehicle models, resulting in low production efficiency and insufficient flexibility, necessitating technological upgrades to improve compatibility. Utility Model Content

[0003] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a multi-position adjustable fork mechanism and device, which changes the pneumatic Y-axis telescopic structure to a motor + synchronous belt structure, enabling multi-position stopping in the Y-axis; at the same time, it adds a multi-position adjustment function in the X-axis of the lifting platform's rear fork, realizing multi-position adjustment of the lifting platform's fork to meet the needs of multi-model production.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a multi-position adjustable fork mechanism, including a lifting trolley assembly and two opposing support frames, wherein one support frame is fixedly connected to the lifting trolley assembly, and the other support frame is slidably connected to the lifting trolley assembly along the X direction; the lifting trolley assembly is provided with an X-direction multi-position adjustment drive mechanism for driving the corresponding support frame to slide along the X direction; a fork is slidably connected to the bottom of the support frame along the Y direction; the support frame is provided with a Y-direction multi-position adjustment drive mechanism for driving the fork to slide along the Y direction.

[0005] A further improvement is that the lifting trolley assembly is equipped with an X-axis slide rail, and the corresponding support frame is connected to the X-axis slide rail via an X-axis slider.

[0009] This utility model provides a multi-position adjustable distance support fork device, including a frame, on which the multi-position adjustable distance support fork mechanism as described above is provided.
