[0017] The present invention has the following beneficial effects:

[0018] After the present invention places the printer shaft core inside the flip component through the clamping component, the flip component is started to move closer to each other, and the printer shaft cores to be welded are spliced ​​together by using the flip component. At this time, the ends of the printer shaft cores that are close to each other will be located inside the work frame. At this time, the laser welding device is started to weld the printer shaft core. When the welding position needs to be adjusted, the power device is started to drive the threaded rod to rotate. When the threaded rod rotates, it pushes the screw hole block to move inside the top groove. When the screw hole block moves, it drives the laser welding device to move through the bent plate, thereby adjusting the welding position of the printer shaft core, thereby improving the convenience of the printer shaft core during welding.

[0019] After the printer shaft core is placed inside the semicircular frame, the printer shaft core is fixed inside the semicircular frame by a clamping component, and a contact plate is arranged inside the semicircular frame. When the bidirectional electric rod pushes the two moving frames to move closer to each other, the moving frame pushes the semicircular frame to move closer to each other through the circular hole frame, and the printer shaft core enters the interior of the working frame for welding along with the movement of the semicircular frame. When the ends of the printer shaft core contact each other, the printer shaft core will squeeze the elastic rod through the contact plate, and at this time, the contact plate can squeeze and limit the printer shaft core through the elasticity of the elastic rod, thereby improving the stability of the printer shaft core during welding and avoiding the printer shaft core from sliding during welding. After the motor is started to drive the rotating frame to rotate inside the circular hole frame, the rotating frame drives the clamping component to rotate through the semicircular frame when rotating, so that the clamping component can rotate along with the semicircular frame and drive the printer shaft core to rotate, so as to perform circumferential welding on the surface of the printer shaft core, thereby improving the convenience of the printer shaft core during welding.

[0020] The present invention pulls the lifting frame to move upward, and when the lifting frame moves upward, it will pull the spring to extend, and will pull the circular groove extrusion plate to move toward the outer end of the semicircular frame. After the printer shaft core is placed inside the semicircular frame, the lifting frame is released, and the lifting frame will move downward through the elasticity of the spring and push the circular groove extrusion plate to extrude and fix the printer shaft core. The printer shaft core can be fixed by releasing the lifting frame, thereby improving the convenience of the operator in fixing it.

[0021] When the semicircular frame of the present invention moves, the connection between the sliding hole plate and the extrusion spring drives the disc to move. When the disc moves, the triangular plate is driven to move through the cylindrical rod and contact the inner wall of the annular groove. When the semicircular frame rotates, the triangular plate is driven to rotate on the inner wall of the annular groove. When the sparks splashed by the laser welding device adhere to the inner wall of the annular groove, the triangular plate can be cleaned by rotating. When the working frame moves, the triangular plate is squeezed to move. When the triangular plate moves, it will push the cylindrical rod to slide inside the sliding hole plate. At the same time, the triangular plate at the other end will extend by the elasticity of the extrusion spring, so that the triangular plate can fit the inner wall of the annular groove.

[0022] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
