The pressure point cylinder 51 can drive the pressure point rotating disk 53 to rotate through the connecting rod 52. When the pressure point rotating disk 53 rotates, it squeezes each pressure point strip 55 through the convex strip 531. The pressure point strips 55 move inward along the pressure point guide seat 54 at the same time, thereby squeezing the sleeve on the positioning platform, so that the sleeve and the screw are pressed tightly to prevent them from falling off. It should be noted that in order to prevent the pressure point strip 55 from crushing the sleeve, one of the pressure point strips is designed as a split structure, and its outer end cooperates with the pressure point turntable 53 and the roller block 56 to be connected to the pressure point strip through a spring 57.

The sealing ring pressing cylinder 81 and the sealing ring pushing cylinder 83 drive the pressing head 87 to descend, grab the sealing ring, reset each cylinder, and move the sealing ring to the top of the turned workpiece. The sealing ring pressing cylinder 81 drives the sealing ring pushing cylinder 83 to descend, and the sealing ring pushing cylinder 83 drives the pressing head 87 to descend, thereby pressing the sealing ring outside the sleeve.
