Description
2axis Automatic Hydraulics Port Welding Machine


I. Design Mission
- It should meet the requirement of automatically welding various ports/nozzles of hydraulic cylinder circular seam.
- MIG welding
- Make sure the welding specification is uniform and even, welding seam has good appearance. Easy and reliable to operate. Quality can meet welding requirement.

III.Welding Specification and Basic Conception
- Welding torch tilts to a certain angle, can be adjusted up-down, side to side and angled turn. Workpiece is fixed while the welding torch is rotating.
- Fixture is used to form workpiece center, to obtain welding seam position, which does not deviate while placing nozzle to cylinder. Do not need spot welding in advance.
- Machine has high voltage and slow wire feeding performance, which ensures reliable arc igniting. It also has low welding voltage and low current for filling crater.
- It adopts shot-distance wire feeding mode.
- Using Japan Panasonic PLC to control the whole operation. CNC system is used to control rotation of machine head. Servo motor is driven by AC servo driver.
- The rotatory head is moved up and down by servo motor, rotary head falls while machine is welding, and lifts while loading and unloading.
IV.Equipment Composition
- Machine is composed of upper, middle, and lower parts.
- Rotary wire feeding mechanism is installed in upper part.
- Middle part is the core component. Rotary head motor-driven feeding mechanism, welding torch rotation mechanism, conductive mechanism, workpiece clamping mechanism, workpiece rotation mechanism, welding torch &torch adjustment mechanism and safety device are all installed in the middle parts.
- The lower part has switch mechanism of workpiece welding station and preparation station.
