The outer shell cannot be restricted from the front and back when it is pushed on the outer shell guide track. Therefore, the outer shell is sensed by a depth sensor to sense whether the side with the blind hole is facing the turntable. If so, the outer shell clamping assembly directly clamps the outer shell on the outer shell guide track and assembles it with the base. If not, the outer shell clamping assembly clamps the outer shell and rotates it 180° before assembling it with the base.

At this time, it is determined whether the shell needs to be rotated 180° according to the sensing structure of the depth sensor. If necessary, the rotating cylinder is started to rotate the second clamping jaw 180°. If not, the piston rod of the fourth cylinder is directly extended to make the shell sleeve on the outside of the base on the positioning tooling, and then the position of the second clamping jaw is reset to prepare for the next clamping.
