This spinning machine and its tail-top mechanism include a frame, and further comprising: a motor mounted on the frame; a drive shaft connected at one end to the output shaft of the motor; a connecting shaft slidably connected at one end to the drive shaft; a connecting member at the other end of the connecting shaft; a mold connected to the connecting member for synchronous rotation; and a translation mechanism mounted on the frame and connected to the connecting shaft to drive the connecting shaft to move. This invention enables the rotational movement of the tail-top mechanism to be synchronized with the rotational movement of the workpiece and the main shaft of the equipment, reducing workpiece slippage and damage.

[0003] During the spinning process of metal products, the workpiece often slips or falls off due to the high rotation speed and high processing resistance. Therefore, many spinning machines have added a tail-top mechanism to help fix the workpiece. However, the current tail-top mechanism lacks active equipment and adjustment mechanism. Therefore, this solution proposes a movable tail-top assembly for spinning machines, which has dual axial and radial adjustment functions, thus improving the functionality of the tail-top mechanism.
