[0001] The utility model relates to the field of six-degree-of-freedom platforms, in particular to an assembled six-degree-of-freedom platform. Background Art
[0002] The six-degree-of-freedom platform is a high-end mechatronic device that can simulate true full-range motion in a three-dimensional space, including three translational degrees of freedom (linear motion in the X, Y, and Z axes) and three rotational degrees of freedom (rotational motion around the X, Y, and Z axes, commonly known as roll, pitch, and yaw).
[0003] The existing six-degree-of-freedom platform fixes six cylinders between the upper platform and the lower platform through bolts and nuts, so that the cylinders drive the upper platform to move in six degrees of freedom. However, when the nuts are connected to the bolts, they may become loose or fall off due to loose installation, fatigue failure, overload, etc., which may cause the upper platform to become unstable.
[0004] Therefore, an assembled six-degree-of-freedom platform has been developed that can limit the first fixing screw and the second fixing screw to prevent the first fixing screw and the second fixing screw from loosening or falling off, thereby preventing the support plate from becoming unstable. Utility Model Content

[0008] Optionally, a second rotating fixing frame and a second fixing screw are further included, the telescopic end of the cylinder is rotatably connected to the second rotating fixing frame, and the second fixing screw is threadedly connected to the second rotating fixing frame.
[0009] Optionally, a second connecting frame is further included, and the second connecting frame is clamped between two adjacent second rotating fixing frames.

[0011] Optionally, a second locking column is further included, and a plurality of second locking columns are clamped on the support plate, and the second locking columns are all clamped and matched with adjacent second rotating fixing frames.
[0012] The utility model has the following advantages: the utility model achieves the effect of limiting the position of the first fixing screw and the second fixing screw by engaging the first locking column with the first rotating fixing frame so that the first locking column blocks the first fixing screw, and engaging the second locking column with the second rotating fixing frame so that the second locking column blocks the second fixing screw, thereby preventing the first fixing screw and the second fixing screw from loosening or falling off and causing the support plate to become unstable.
