LHZ Light Duty Fixed Base Column Electric Revolve Welding Manipulator

1. Characteristics of Light duty Fixed Base Electric Revolve Welding Manipulator:

1) Structure: The light duty Automatic Welding Manipulator of this product section, has basically the similar structure as the previous product of “Light duty Stationary Base Manual Rotating Welding Column and Boom”;

2) The major distinction between the two models of Weld Manipulator is, during operation, column revolve is driven with motor reducer, instead of pushed by hand;

3) Application: Motor revolving style of Welding Manipulator for Industry is mainstream configuration, in this widely applied one kind of product from Pipe Welding Equipment, a leap forward toward welding automation.

2. Technical Summary on LHZ series Light duty Fixed Base Column Motor Revolve Type of High Efficiency Welding Column and Boom:

1) Two Main Purposes of the Automatic Welding Manipulator:

a) Longitudinal Seam Welding: By means of boom horizontal traveling, longitudinal seam welding is performed on various workpieces of pipes and tubes;

b) Circumferential Seam Welding: Working together with Welding Rotator, both internal and external circumferential seam welding is performed on workpieces of pipes and tubes;

2) Mechanical Systems in the Weld Column and Boom:

As can be seen from the attached pictures, a set of motor drive moving and revolving Welding Column and Boom has main units of: 

a) Fixed style cross base;

 b) Horizontal extending and vertical lifting boom;

c) Upright column and its column revolving mechanism;

d) High precision cross slide;

e) Motor reducers, for driving elevation and later movement of horizontal boom respectively;

f) Horizontal boom horizontal stroke; 

g) Upright column revolve mechanism;

h) Guiderail system;

3) SAW Welding Systems in the Welding Manipulator with SAW:

Besides SAW (Submerged arc welding) power supply, other requisite assistant welding units equipped with the Welding Manipulator include:  

Welding function units of Welding Manipulator: (Fig.1)

a) SAW welding flux recovery machine, flux hopper, flux conveying tube, which is fit at front end of the boom. Please check attached picture and above photo in yellow color;

b) SAW Welding wire feeding assemblies;

c) Welding torch position control cross slides;

4) Boom Movement Mechanism during Running of the High Precision Welding Manipulator:

a) Based on Diameter of Pipe: During work of the Automatic Welding Column and Boom, boom can move up and down in constant speed under motor drive, to accommodate workpieces of various diameters (parameters see specification table of below segment);

b) The main working motion in the Welding Column and Boom is, boom can extend and shrink along horizontal direction, which means travel leftward and rightward, for performing longitudinal welding on workpiece pipes. In other words, horizontal moving speed of boom is SAW welding speed of the Welding Manipulator, which is adjustable controlled with A.C. inverter;

5) Guiding Element in the LHT Light duty High Precision Welding Manipulator:

For this light duty Welding Manipulator for Industry, in terms of both horizontal and vertical direction movement of boom, it is guided with advanced precise and abrasion proof V cross shape guideway, or called triangular cross shape guideway, making this Pipe Welding Equipment a truly High Precision Welding Manipulator. Please check below picture:

6) Transmission Unit in the LHT Light duty High Precision Welding Manipulator:

Also, for this light duty automatic Weld Manipulator, in view of boom elevation transmission, considering the corresponding small stroke, it is adopted with leadscrew, which is different from chain sprocket as in the case of Medium duty and Heavy duty Welding Manipulator. Please check below picture: 

Leadscrew transmission in Welding Column and Boom: (Fig.3) 

7) In all, design and manufacture of this series of Pipe Welding Equipment fully consider specialty of each configuration and customer demand, making it a truly high quality welding manipulator.
