For this reason, China Patent Publication No. CN218425632U discloses a CNC lathe with automatic feeding, which improves the feeding problem of shaft workpieces. By rotating the transmission screw, the loading barrel is driven to slide to the center of the three-claw clamp disk, and then the top is driven by the push cylinder to push the top of the inner wall of the loading barrel into the center of the three-claw clamp disk to realize automatic loading, and the shaft workpiece is pushed for feeding by the electric cylinder installed on the storage box.

[0004] However, the space size of the material storage box in this solution is fixed. When placing shorter shaft workpieces, the workpieces are easily scattered in the material storage box, which causes congestion and blockage in the material guide trough.

When loading workpieces with smaller diameters, it is easy for multiple workpieces to fall from the material guide trough at the same time, and when loading workpieces with larger diameters, the material guide trough is easily blocked and cannot pass normally.
