Pin trial assembly method

The invention discloses a pin trial assembly method which comprises the following steps: S1, fixing a to-be-assembled object on a workpiece supporting seat, and mounting a pin on a pin screw plug storage platform; s2, a quick change mechanism clamps the tail end of the three-dimensional scanning camera, and then a pin hole in the to-be-assembled object is recognized and positioned; s3, the quick change mechanism clamps the disassembly and assembly tail end of the pin, and then picks up the pin from the pin plug storage platform; s4, the outer wall of the pin is coated with red lead; s5, pins are inserted into the pin holes; in the pin-in process, if the force transducer recognizes that the pin cannot be pinned in when the pin-in force reaches a threshold value, interference fit is judged to exist, then the pin hole is expanded, and finally, the pin is assembled into the pin hole; and S6, taking out the pin from the pin hole, clamping the tail end of the endoscope camera by a quick change mechanism, performing
