The shaft sleeves 604 and other accessories arranged on the shaft sleeves 604 are correspondingly arranged in four groups, and are symmetrically distributed about the center of the turntable 5.

[0026] Furthermore, a first preload spring 607 is sleeved on the outside of the sleeve 604 and located between the turntable 5 and the push shaft 605. The first preload spring 607 is used for the return of the push shaft 605. A second preload spring 608 is sleeved on the outside of the push shaft 605 and located between the positioning guide mold sleeve 606 and the sleeve 604.

[0027] Furthermore, the crown pushing spring mechanism 7 includes a second cylinder 701, which is fixedly connected to the first mounting frame 4, and the output end of the second cylinder 701 is fixedly connected to a push rod 702.

[0029] The utility model uses steps as follows: when the crown spring and cylindrical terminal automatic insertion assembly mechanism is in use, the crown spring feeding manipulator 2 carries the clamp to reduce the diameter of the crown spring and puts it into the positioning guide die sleeve 606. At this time, the crown spring has not been completely put in place. The cam divider 1 controls the turntable 5 to rotate counterclockwise by 90 degrees, and the crown spring is transferred to the crown spring pressing mechanism 6 station. The first cylinder 602 drives the pressing rod 603 to press down and completely press the crown spring into the positioning guide die sleeve 606.

The push shaft 605 continues to extend. Since the notch of the positioning guide die sleeve 606 is one millimeter smaller than the slot of the cylindrical terminal, when the crown spring is pushed to the slot of the cylindrical terminal, the crown spring automatically releases its elasticity, and the diameter of the crown spring returns to normal size, close to the inner hole wall of the cylindrical terminal, and the installation is completed.
