[0002] Shaft fasteners are mechanical components specifically designed to fix, connect or support shaft parts. Through methods such as threaded connection, pressing, and positioning, reliable cooperation between the shaft and other parts is ensured. For example, shoulder screws, set screws, and pin fasteners all belong to shaft fasteners; When machining existing fasteners on a lathe, usually a long metal rod is machined into several fasteners. However, when machining the metal rod, since the metal rod is long, the fixed position of the metal rod is far from the machining position, and it is easy for the metal rod to shift under force during machining, resulting in a decrease in the machining progress; in order to ensure that the distance between the fixed point position and the force point position is relatively small during the machining process, it is necessary to frequently adjust the fixed point position, which has cumbersome steps and low work efficiency; when a fastener is machined, it needs to be cut off from the metal rod, and after cutting off, the fastener will fall, and the falling of the fastener may cause damage due to collision, increasing the defective rate.

[0012] A process for fastener processing uses the above-mentioned fastener processing lathe, including the following steps; The fixed chuck fixes one end of the metal rod to be processed. The moving column moves to drive the fixed rod to move horizontally. The moving plate moves to drive the fixed rod to move towards the metal rod. When the fixed rod contacts the metal rod and squeezes and fixes the metal rod, the moving plate stops moving to fix different positions of the metal rod; when a part of the rod body of the metal rod is processed into a fastener, the moving ring plate moves to move the processed part of the metal rod to the inside of the moving ring plate. When the lathe cuts off the processed part, the blanking magnetic ring adsorbs the processed fastener. When a part of the rod body of the metal rod is processed, the fixed chuck stops rotating. The limiting push block moves and drives the limiting slider to move. The movement of the limiting slider releases the limit on the moving block. The moving block moves, and the fixed rod releases the fixation on the metal rod. The moving wedge block moves to drive the moving limiting rod to move.

By repeating the operation, the metal rod is processed into several fasteners.

[0013] Compared with the prior art, the present invention provides a fastener processing lathe and a process for fastener processing, having the following beneficial effects: 1. The fixed chuck fixes one end of the metal rod to be processed. The moving column moves to drive the fixed rod to move horizontally. The moving plate moves to drive the fixed rod to move towards the metal rod. When the fixed rod contacts the metal rod and squeezes and fixes the metal rod, the moving plate stops moving to fix different positions of the metal rod; fixing the longer metal rod at different positions can prevent the longer metal rod from shifting during the processing.

[0014] 2. When part of the metal rod is processed into a fastener, the movable ring plate moves, causing the processed part of the metal rod to move inside the movable ring plate. When the lathe cuts off the processed part, the blanking magnetic ring adsorbs the processed fastener, magnetically collecting the processed fastener to prevent the processed fastener from being cut off and falling from the metal rod, resulting in damage to the fastener.

[0015] 3. After the processing of part of the metal rod is completed, the fixed chuck stops rotating, the limit push block moves and drives the limit slider to move. The movement of the limit slider releases the limit on the moving block, and the moving block moves. The fixed rod releases the fixation of the metal rod. The moving wedge block moves and drives the moving limit rod to move. The movement of the moving limit rod releases the limit on the moving column. The pushing plate moves to push the moving column to move, causing the position of the fixed rod to move. After the movement is completed, the moving wedge block moves back to its original position, the moving limit rod moves, and limits the moving column. The limit push block moves back to its original position, the moving block moves back to its original position, the limit slider moves, and the limit slider re-limits the moving block. The fixed rod re-fixes the metal rod. The fixed chuck rotates again, and the lathe processes the metal rod while supporting it. By repeating this operation, the metal rod is processed into several fasteners; changing the fixing position of the metal rod does not affect the processing of the metal rod and improves the applicability of the equipment.
