The coordination of multiple people lifting is poor and the operation is difficult, resulting in high labor intensity for operators, low assembly efficiency, and easy assembly quality problems that cause rework. At the same time, there are certain safety hazards. In order to successfully complete the final assembly and docking of tube-mounted missiles, this device is specially designed.
[0003] Through research and analysis, it is believed that in order to cooperate with the existing missile body support device and launch tube fixing device to complete the assembly and docking of tube-loaded missiles, the device must have the following functions: 1. The platform can achieve freedom adjustment in multiple directions during the docking process; 2. The platform has a positioning and fixing function to avoid the position of the platform from shifting when performing other operations; 3. During the missile loading process, the missile body can be accurately and easily moved axially and rotated circumferentially to realize the loading of the missile into the launch tube.

[0043] Example 1
[0044] The tube-mounted missile has large geometric dimensions and heavy weight. During the final assembly process of loading it into the launch tube, it is necessary to complete axial alignment, axial movement, circumferential rotation, etc., and the final assembly process must be safe and stable to ensure assembly quality and efficiency.
