Multi-degree-of-freedom missile bay section butt joint device

The invention discloses a multi-degree-of-freedom missile bay section butt joint device. The multi-degree-of-freedom missile bay section butt joint device comprises a vehicle body and a butt joint system. The vehicle body comprises a vehicle frame and wheels. The wheels are installed under the vehicle frame. The butt joint system is installed on the vehicle frame and comprises lifting mechanisms, posture adjustment mechanisms, feeding mechanisms and supporting mechanisms. The lifting mechanisms used for lifting missile bay sections are fixed to the vehicle frame. The lifting mechanisms are sleeved with one ends of the posture adjustment mechanisms, and the other ends of the posture adjustment mechanisms are connected with the feeding mechanisms. The supporting mechanisms are installed on the feeding mechanisms. According to the multi-degree-of-freedom missile bay section butt joint device, the advantages of a hoisting butt joint mechanism and the advantages of a lead screw and nut butt joint mechanism are combined; a flexible butt joint form is adopted, and adjustment of the butt joint postures of the missile bay sections is achieved through ball hinge assemblies and limiting assemblies; operation is flexible and easy, and butt joint can be achieved rapidly, safely and reliably; in addition, the structure is simple, and the manufacturing cost is low; the butt joint system is installed on the vehicle frame, thereby being suitable for being transferred from one site to another site.
