The control panel 17 makes it easy for the staff to operate the device.

[0031] In use, firstly, one end of the cylinder barrel to be welded is moved to the middle of the hydraulic three-jaw chuck 124. Then, the hydraulic three-jaw chuck 124 is tightened by the control panel 17 to clamp and fix the cylinder barrel. Then, the other end of the cylinder barrel is located on the surface of the placement recess 131, and the piston rod of the cylinder barrel extends out of one side of the placement recess 131. Next, the electric lifting rod 142 is extended by the control panel 17, which drives the lifting slide 144 and the pressure plate 145 to move down.

[0032] Subsequently, the control panel 17 is used to control the retraction of the electric lifting rod 142, which moves the pressure plate 145 to its original position. The control panel 17 is also used to activate the extension of the hydraulic lifting rod 133, which moves the mounting bracket 134 and the support rotating cylinder 135 upward, so that the surface of the support rotating cylinder 135 contacts the surface of the cylinder. Then, the control panel 17 is used to activate the servo electric cylinder 165 and the electric slide rail 166 to work, and then the laser welding machine 168 is moved to the position where the piston rod and the rod head are connected. The laser welding machine 168 is then activated to weld the connection position. At the same time, according to the welding requirements, the control panel 17 can be used to activate the servo motor 122 to rotate, which in turn drives the mounting base 123 and the hydraulic three-jaw chuck 124 to rotate, so that the cylinder and the rod head are rotated accordingly. The top holding column 155 drives the rotating disk 154 to rotate accordingly on the mounting disk 153, so that the welding operation on the other side of the connection position can be performed until the entire cylinder is welded.
