The two moving stoppers 430 are fixed to the two jaws of the grasping cylinder 420, and the two moving stoppers 430 can be pressed against both ends of the shaft 10.

When the short shaft rod 10 needs to be conveyed, the shaft rod 10 is placed on two mutually parallel conveying chains of the first conveying chain assembly 200, the handle rocker 340 is rotated, and the distance between the two first baffle plates 310 is adjusted, so that the two first baffle plates 310 are respectively close to two ends of the shaft rod 10, and it is ensured that the relative position of the shaft rod 10 along the axial direction is difficult to change greatly in the conveying process, and the shaft rod 10 is convenient to be positioned by the first positioning assembly 400 on the next step. When the shaft 10 is transferred to the other end of the frame 100, the shaft 10 needs to be accurately positioned first, and then the shaft 10 is taken away by the robot gripper and enters the next processing step. In order to achieve accurate positioning of the shaft 10, in the present embodiment, when the shaft 10 is conveyed to the end of the frame 100, the first sensor 410 detects that the shaft 10 has reached a specified position, at which time the two jaws of the gripping cylinder 420 are contracted, and the two moving stoppers 430 respectively grip one end of the shaft 10, thereby fixing the shaft 10 between the two moving stoppers 430. The robot gripper can now pick up the shaft 10 exactly at the previously set position.
