Multi-freedom platform requiring small installation space

The utility model discloses a multi-freedom platform requiring small installation space and belongs to the technical field of vehicles. With small structure, micro-adjustment can be accurately aligned without the use of a complicate mechanical structure. The multi-freedom platform comprises an upper support plate assembly, a lower support plate assembly, a plurality of oil cylinders, a support shaft, a connection shaft, an oil cylinder support seat and a grooving nut. With a structure of two layers of thin plates, two types of adjusting oil cylinders are arranged between the two layers, so multi-freedom micro adjustments, such as transverse movements, longitudinal movements, clockwise rotation and anticlockwise rotation can be achieved between the two thin plates; and with small installation space, automatic and accurate docking micro adjustments for work conditions of soft assembling production line and ground security filling docking operation can be realized.
