Advanced Electric Control Automatic Welding Column And Boom

1. Main Units of Electric Welding Column and Boom:

1) The Electric Welding Manipulator, in terms of its working mode, is mainly composed of operating mechanism, electric control system, welding power source, and process technology guarantee unit;

2) All the motions of the welding machine tool are powered with motor; Working speed is controlled and displayed with A.C. inverter; Working logic is controlled with electric control elements:

Hand held operating panel of Wuxi JACK exported Welding Manipulator, integrated with major working motion, and working speed management together with display: (Fig.1)

3) Drive Mode: There is no hydraulic and or pneumatic system installed in this automatic column and Boom welding equipment. This is the reason we name this LHZ series  equipment electric type machine tool.

2. Operating Mechanisms of LHZ Automatic Welding Column and Boom:

This mainly consists of:

1) Mechanical Frame of Electric Weld Manipulator:

a)  Mechanical fixed base bed for stationary structure models;

b) Motor drive moving trolley and moving rails for moving structure models;

c) Horizontal extending boom and its both direction (Along vertical and horizontal way) drive and transmission systems;

d) Upright erected column, and its revolve (If exist) drive and transmission unit;

e) Cross slides saddle and its guiding eccentric rollers: Motion ankle of horizontal boom movement;

f) Heavy duty square section precise linear guiderail for movement of the entire set of Welding Column and Boom;

g) Electric cable drag chain;

2) Welding System in Automatic Welding Manipulator:

a) Welding power supply, welding torch and its precise position managing unit, welding wire feeder, SAW welding flux recovery unit;

b) Welding torch position manipulating cross slides at the front end of horizontal boom;

c) Welding seam tracker, and welding seam oscillator;

3) Electric Control Unit of LHZ Electric Welding Column and Boom:

a) Electric control system of the automatic column and boom welding machine;

b) Control console of welding power supply, welding wire feeder, welding seam tracing unit respectively;

4) Power Source Unit of LHZ Electric Weld Manipulator:

A.C. Motors for driving horizontal boom up and down movement along the upright column, horizontal movement, column revolve and trolley traveling respectively;

5) Transmission Units of Electric Welding Column and Boom:

a) Horizontal Boom Up and Down Movement:

i.  Leadscrews for transmitting light duty models;

ii.  Chain sprocket for transmitting medium duty models, as well as heavy duty models;

b) Gear and rack for transmitting boom horizontal movement;

c) Slewing support (Cross roll bearing) for leading upright column into revolve.

3. Process Technology Guarantee Unit of LHZ Electric Welding Manipulator:

1) Welding wire guiding mechanism;

2) Contact tube for starting on welding operation;

3) Optional function unit: Welding seam tracking mechanism;

4) Optional function unit: Graphic video monitor;

5) Optional function unit: Oscillator (for performing GMAW CO₂ welding);

To adjust on welding torch/ welding wire position during running period in precise way, for the purpose of delivering persistent high precision of welding finished product.

4. Transmission Manner of Horizontal Boom Movement in Electric Welding Column and Boom:

1) Horizontal Boom vertical movement transmitted with Chain sprocket in Automatic Welding Manipulator:

For light duty models equipment sometimes it is leadscrew: (Fig.2)

a) Relative lower manufacturing cost, and reliable running;

b) Positioning precision is inferior to gear and rack. This direction of horizontal boom movement (up and down) is for adjusting on boom vertical position to fit for changing diameters of workpieces;

c) It is fine with chain sprocket transmission for carrying out horizontal boom elevation;

2) Boom Horizontal Movement Transmitted with Gear and Rack in Automatic Welding Column and Boom:

For Wuxi JACK LHZ3030 medium model: (Fig.3)

a) The highest manufacturing cost among all options of transmission manner;

b) Reliable and smooth running of the Weld Manipulator;

c) This can get the best degree of positioning precision among all options, which is the most appropriate solution for horizontal Boom back and forth movement, or welding management in the automatic welding machine tool.
