At this time, the motor three 360 ​​can drive the pin shaft and the auxiliary plate 12 to rotate, which is convenient for the installation of the elastic component 15.

[0078] Then, the other fixed plate 11 on the feed frame 21 is clamped by the electric clamp 48, and then the fixed plate 11 is moved to the assembly groove 31, and the fixed plate 11 is pressed onto the auxiliary plate 12, and then the position of the auxiliary plate 12 is adjusted by rotation, and then the elastic component 15 is fixedly installed in the two through grooves 13 by the mechanical arm, so that the two ends of the elastic component 15 are respectively aligned with the pin holes of the auxiliary plate 12 and the fixed plate 11.

[0079] Then use the robotic arm to insert the fixing pin into the connection between the auxiliary plate 12 and the elastic component 15, and finally use the cylinder 24 to lift the lifting rod 35, and use the spring 4 352 to lift the bracket 342 upward, so that the pin rod under the through hole 311 moves upward. After the pin rod passes through the through hole 311, under the lifting action of the punch block 351, the pin rod passes through the two fixed plates 11, and the two pin rods pass through the connection between the elastic component 15 and the fixed plate 11, so as to lock the elastic component 15.

[0080] During the lifting process of the punch block 351, the output end of the cylinder 5 420 contracts and moves upward. At this time, the upward movement of the push rod 431 will push the inclined rod 452 upward, driving the end of the rocker rod 45 with the straight groove 451 to rotate downward, and then pressing the pressure plate 49 downward to press one end of the pin rod. With the cooperation of the punch block 351 and the pressure plate 49, the pin rod is riveted to the fixed plate 11 to complete the assembly.
