The X direction and the Y direction are perpendicular to each other.
Two clamping block type clamping jaw assemblies 160 capable of moving along the radial direction of the rear rotating disk 112 are installed on the rear rotating disk 112 along the X direction, and two clamping block type clamping jaw assemblies 160 capable of moving along the radial direction of the rear rotating disk 112 are installed on the rear rotating disk 112 along the Y direction.
When the roller jaw assembly 150 is clamping a workpiece, there is a gap between the clamp block jaw assembly 160 and the workpiece.
The rotary support inner ring 180, the inflation cavity assembly 140, the front rotary table 111, the rear rotary table 112, the rotary gear 130 and the rotary table connecting ring 113 jointly enclose a closed installation cavity.
