Problems solved by technology
At present, the multi-degree-of-freedom motion platform has problems such as single driving mode and inability to move flexibly
Multi-degree-of-freedom motion platforms are divided into serial motion platforms and parallel motion platforms. The serial motion platforms have low motion efficiency but high operational stability, while the parallel motion platforms overcome the problem of low efficiency and can complete operations efficiently. However, there are still a series of problems such as unstable operation and insufficient degrees of freedom.
In the previous design of multi-degree-of-freedom motion platforms, the degree of freedom design is relatively limited, and there is a problem of single drive during operation. It can realize up-and-down motion and sideways motion, but lacks a large-scale motion mechanism, and cannot perform large-scale platform motion, and the platform fixed

A hybrid drive mobile multi-degree-of-freedom parallel motion platform, including a first-layer folding mechanism, a second-layer rotating mechanism, a third-layer mobile suction cup mechanism, and an attitude monitoring module; the first-layer folding mechanism includes an upper top plate, a lower bottom plate, a folding Frame and linear drive; a folding frame is arranged between the upper top plate and the lower bottom plate; the second layer of rotating mechanism includes flange cover, upper flange, worm gear, worm, worm gear frame, lower flange, motor and motor frame; the third layer The mobile suction cup mechanism includes a support plate, a telescopic suction cup device, a seat plate, a universal wheel assembly and a support rod; there are telescopic suction cup devices on both sides of the support rod, and the suction cups of the telescopic suction cup device can freely shuttle between the seat board and the seat board. A universal wheel assembly is also installed on the bottom surface of the seat, and an attitude monitoring module is also installed on the seat plate. The invention has the characteristics of compact structure, flexible adjustment, large moving range, easy operation and good stability, and is suitable for multi-degree-of-freedom attitude adjustment and motion control.
Description
technical field [0001] The invention relates to a parallel motion platform, in particular to a hybrid drive mobile multi-degree-of-freedom parallel motion platform and a control method. Background technique [0002] Motion platforms are widely used in industrial production, entertainment and other fields, such as motion simulation, stability compensation, dynamic simulation, etc.; parallel mechanisms are widely used in sports because of their advantages such as high rigidity, strong bearing capacity, and easy trajectory planning and control. platform. [0003] At present, the multi-freedom motion platform has received widespread attention in the market. The multi-degree-of-freedom motion platform is composed of multiple electric cylinders, six upper and lower universal hinges, and two upper and lower platforms. The lower platform is fixed on the foundation. With the help of the telescopic movement of multiple electric cylinders, the movement of the upper platform in multipl...
