[0002] In the assembly process of large-diameter shaft parts, cranes are mainly used for hoisting and manual docking assembly. The assembly process is not only low in precision but also inefficient. Therefore, it is urgent to adopt automated docking assembly technology to control the entire assembly process and improve assembly efficiency. Accuracy and Assembly Efficiency

According to the search, the patent disclosure of patent CN 108098710 is a trackless transfer platform. The patent realizes a large-scale transfer through the transfer platform. The adjustment of three degrees of freedom has the following disadvantages: 1. When the offset distance between the center of gravity of the component and the center of gravity of the transfer platform is large, a large eccentric load moment will be generated on the transfer platform, which will affect the assembly accuracy and reduce the assembly efficiency. The platform is damaged; 2. When moving in a large range, the transfer platform cannot meet the requirements of the slope during the transfer process; 3. When adapting to the docking assembly of parts with different diameters, it is necessary to manually replace the tooling, which increases the time for preparation work, and When the diameter of the same shaft part is different at different positions, different tooling needs to be replaced, and the overall assembly efficiency is reduced; 4. The vertical lifting height of the attitude adjustment mechanism is limited, which cannot adapt to the assembly and docking of parts of different heights; 5. When installing parts with larger diameters, The positions of the two sets of fulcrums of the tooling base remain unchanged, and as the diameter increases, the angle between the two fulcrums and the axis of the component becomes smaller, the center of gravity is higher, and the assembly stability becomes worse; 6. Manually move in the moving direction along the axis of the component When using manual direct push, the accuracy is poor, and the two sets of attitude adjustment mechanisms cannot realize linkage and separate movement, which reduces efficiency; 7. The rack in the anti-backlash rolling mechanism adopts arc shape, and the guide rail adopts arc shape , directly bears the gravity of the components, and the small deformation has a great impact on the entire fine-tuning accuracy; resulting in low overall assembly efficiency
