Description

technical field [0001] The invention relates to a parallel assembly mechanism with six degrees of freedom, in particular to a parallel assembly mechanism with six degrees of freedom for longitudinal motion simulation. Background technique [0002] At present, there are many plans for the assembly and demonstration platform of longitudinal motion simulation. One solution is that the active end simulator generates a large impact force to achieve impact butt joint, and then the locking force between the active end and the passive end is buffered by the impact spring. However, this scheme has a greater impact and is more destructive to the mechanism itself. The second solution is to use the visual sensor to correct the assembly position of the active end and the passive end, and then use the motor to drive the two parts for docking assembly. The disadvantage of this solution is that there is a large position error after assembly, and the stability and safety of the overall mec...
