3. Main machine introduction
This machine is used for cylinder upper shell and lower shell welding, it adopts seam vision tracking device, automatic imaging to tracking welding seam, welding the circumferential seam automatically, no need of manual intervention. It adopts Panasonic 500GS (special) high-speed pulse MIG welding source. Welding speed can reach to 1000mm/min. It adopts double internal cooling MIG torch, it is suitable for long time welding. It is equipped with Supercooler automatic circulating cooling water tank to cooling the welding torch circularly. It adopts inlet workpiece conveyor, magnetic loading arms, three-station loading and unloading device, self discharge roller, outlet conveyor system to convey the unwelded cylinder from inlet conveyor to the clamping position of circumferential welding machine, then convey the welding finished cylinders from the circumferential welding machine to outlet conveyor. This production line is fully-automatic operation without any manual operation, only one person for watching and managing.
This machine adopts horizontal biaxial structure, principle shaft and tailshaft are the same shaft, air cylinder drive advance and retreat. Moving towards clamping compress or loosening the workpiece. Principle shaft is driven by gear motor, Mitsubishi frequency converter speed regulating. Principle shaft and tailshaft are equipped with welding mould, welding torch position can be adjusted along the direction of cylinder axial line, the welding torch is equipped with micro-adjusting mechanism to delicate fine-tuning the welding torch position. Main head is equipped with vision tracking system, X-Y stepping shaft driven welding torch. Automatic imaging tracking, automatic finding, automatic finish the step of arc starting, welding and arc suppression. Machine head is equipped with smoking pipe to exhaust gas. It is equipped with magnetic loading arms, three-station loading and unloading device, inlet and outlet conveyor line, self discharge roller.
