LHZ Light Duty Travelable Trolley Column Manual Revolve Welding Manipulator

1.  Outline on Working Features of Light duty Manual Revolve Traveling Welding Manipulator:

1) Additional Functions:  The Light duty Welding Manipulator of this product section, compared with the earlier introduced 2 types of fixed base: Stationary Manual Revolve Welding Manipulator, and Stationary Electric Motor Revolve Welding Manipulator, has added ability of moving along rails driven under motor;

2) With this additional degree of freedom, such Welding Equipment is a kind of moving capability Welding Column and Boom. As can be seen from attached master photo and below, the machine has a trolley base moving on parallel rails:  

Motorized trolley of moving Welding Column and Boom: (Fig.1)

2. Structure and Composition of Light duty Manual Turning Moving Welding Column and Boom:

1) Typical structure of a set of traveling style Cross Slide Welding Manipulator can be seen from below sketch:

Design sketch of motor drive moving Welding Column and Boom: (Fig.2) 

2) Checking from the above sketch and attached photos, a set of classical automatic moving Welding Manipulator is assembled into being in the form of modular assembly;

3) Working parts of any set of Welding Manipulator can be divided into 2 groups of standard and optional. Of which, the standard elementary units are indispensable for a set of Cross Slide Welding Manipulator, which builds up skeleton of the Welding Equipment;

4) Optional Functions: Meanwhile, optional function units make this Welding Equipment into a more powerful, versatile and special purpose welding equipment. For example, Welding Manipulator with Strip Cladding.

3. Basic Standard Components in Welding Column and Boom:

1) Mechanical Base Bed in Welding Manipulator:

It is foundation for this type of Welding Equipment, including stationary base bed for Fixed Base Welding Manipulator, and movable trolley for Traveling Welding Manipulator;

2) Upright Column in Welding Column and Boom:

This unit is of fixed manner in terms of elevation and horizontal movement, and of revolving manner in manual and or motor drive mode;

3) Horizontal Boom in Welding Column and Boom:

This is working hand in any set of Welding Manipulator, with capabilities of both X axis movement, and Y axis up and down;

4) Cross Slide in Welding Manipulator:

The other name of cross slides is saddle. In operation of Welding Column and Boom, it plays role of hinge and pivot for position change of welding torch;

5) Slewing Support for Column Revolving in Welding Column and Boom:

This is outsourced part in Welding Column and Boom, making sure accurate, stable, and smooth rotating positioning of column, during working period;

6) Welding Unit in Welding Manipulator:

This is indispensable working cell in any kind of Welding Equipment, including welding torch and welding power source;

7) SAW Welding Flux Recovery Unit in Welding Column and Boom:

This is unique configuration in SAW Welding Column and Boom, including flux hopper, flux recycling machine, flux sending tube, etc.

4. Welding Supplementary Unit in Welding Manipulator:

This group guarantees smooth and satisfactory welding operation in the Welding Column and Boom. It belongs to optional units, but are selected by customers in majority conditions, including:

1) Welding Seam Tracing Unit in Welding Manipulator:

There is a laser generator equipped on the welding torch of the Welding Manipulator, which indicates actual position of welding torch during welding: Whether the position is correct, or offset;

2) Video Monitor in Welding Column and Boom:

a) Function: This is especially useful, when the Welding Column and Boom performs internal circumferential welding inside tube: The horizontal Boom extends into the pipe, the video monitor can give real time information on what is happening inside the workpiece tube:

b) The other Welding Equipment utilizing this unit is Large Pipe Internal Welding Machine;

3) Strip Surfacing Unit in Welding Manipulator with Strip Cladding:

This is unique configuration in built-up welding mode of Welding Column and Boom.

5.  Drive and Transmission in Welding Column and Boom:

1) The Horizontal Boom Horizonal Movement in Welding Manipulator:

This direction involves welding process. It is driven with motor reducer, and transmitted with gear and rack, making the Welding Manipulator a high precision Welding Column and Boom;

2) The Horizontal Boom Elevation Movement in the Welding Column and Boom:

Driven with motor reducer. As to transmission, for light duty Welding Manipulator, as introduced in the previous product, it is by means of leadscrew; For medium duty and heavy duty Welding Manipulator, it is by means of chain sprocket;

3) Motor Drive Trolley of Traveling Welding Manipulator:

Driven and transmitted with motor reducer, in the speed of constant 1700 mm/min. for light duty Welding Manipulator, and 2000mm/min. for medium duty and heavy duty Welding Column and Boom.
