The design scheme of a welding robot workstation for the long welding seam of aluminum alloy plate

The design scheme of a welding robot workstation for the long welding seam of aluminum alloy plate

1. Basic information of the workpiece

  The name and drawing number of the work piece: Aluminum alloy ship board jigsaw 

  Workpiece size specifications: length X width X height, 8000X1600X6 four pieces spliced

  Workpiece material: aluminum alloy; thickness 6mm

  Workpiece weight: about 1000 Kg

2. Workpiece welding requirements:

   The appearance of the welded parts is beautiful, and the double-sided welding seam is melted.

3. Schematic diagram of the cross-section of the workpiece

Welding process and automatic welding requirements for the workpiece to be welded                                 

1. Welding process

  Welding method: MIG gas shielded welding;

  Protection method and diameter of welding wire: Shielding gas: Ar welding wire Ф 1.2;

  Welding method: automatic welding;

  Workpiece loading and unloading method: manual loading and unloading.

2. Requirements of automatic welding for the welded workpiece:

 The surface of the workpiece to be welded shall not have oil rust and moisture that affect the welding quality;

 The workpiece to be welded must not have burrs that affect positioning;

 The error between the shape of the welded workpiece and the weld seam is ≤±0.5mm;

 The gap between the welded workpieces is ≤ ± 0.5mm.

2. Overall overview of the program

Equipment name: Aluminium alloy long plate seam welding workstation.

 Number of equipment: one set.

 Equipment use: used for the joint welding of aluminum alloy medium and thick plates. If you need to weld other similar products (within the size of this equipment), you need to replace the fixture as a whole.

 Workstation composition: consists of a gantry type aerial two-track welding manipulator, two sets of Cloos welding power sources, a large-size jigsaw fixture, two sets of welding robot welding systems, two sets of laser real-time trackers, and two sets of jigsaw butt seam auxiliary mechanisms , A set of assembly control system and other components.

 Workstation layout: The welding robot is arranged in parallel and upside down under the beam of the gantry manipulator, and moves to the welding position through the gantry robot operating frame. The jigsaw fixture fixes the workpiece and aligns the joints of the workpieces, so that the gap between the welds is even, and the height of the two mating plates is flat and easy to weld.

 Equipment operation process: manually hoist the workpiece to the auxiliary platform corresponding to the welding fixture for seam positioning and compression, then move the operating machine and the robot welding torch in place, start the button box to start the operating machine for automatic welding, no manual labor is required in the automatic welding process Intervention.
