1. The Structure of Head and Tail Welding Positioner:

1) The Two Body of Head and Tail Welding Positioner:

a) Head and tail Welding Positioner can be viewed as double body welding turntable, with the working parts connected in between. Or, it can be looked as two sets of L type Welding Positioner stand facing toward each other; 

Working Site of Wuxi JACK Head and Tail Welding Positioner (Fig.1)

b) In Head and Tail Welding Positioner, the two mechanical body of supporting bracket can be either joint together into an integral frame, by means of a piece of horizontal beam, or individually separated from each other. Please check the above small photo;
c) Under the condition of separately arranged supporting brackets, one of the supporting brackets can move along the rail, to cater for changed length of workpiece in the Head and tail Welding Positioner;

2) The Original Welding Turntable in Head and tail Welding Positioner:

a) In head and tail Welding Positioner, welding turntable in conventional standard Welding Positioner and L type Welding Positioner is reduced to welding fixture for securing workpiece;
b) In one set of head and tail Welding Positioner, there is one piece of securing welding fixture on each set of the two supporting brackets.

2. The Working Mode of Head and Tail Welding Positioner:

With reference to the two sets of lateral supporting brackets, the head and tail Welding Positioner has the flexible way of working. There are three optional ways in its welding turntable:

1) Single Axis Revolving of the Welding Turntable around the Horizontal Axis:

This is the basic and indispensable working axis of the head and tail Welding Positioner. As you can find from the above big photo of this page, operator was welding on the structure member after its welding point is turned to proper welding position; 

Design Sketch on Single Axis Fixture type Head and Tail Welding Positioner (Fig.3)

2) Two Axis Revolving and Elevation of Welding Turntable:

When the working parts to be welded has fairly large size of cross section, the head and tail Welding Positioner should have ability of up and down within certain vertical stroke, from the frequently 800 ~ 1000 mm, to custom made higher level;

3) Three Axis Revolving, Rotation and Elevation of Welding Turntable:

a) In complicated head and tail Welding Positioner, a smaller size welding turntable is installed on the horizontal beam, and rotates 0°~360° freely;
b) This additional degree of freedom makes the head and tail Welding Positioner applicable for welding irregular shape and distributed welding seams of working parts.

3. The Applicable Working Parts for Head and Tail Welding Positioner:

1) Head and tail Welding Positioner is developed specifically for welding working parts with long length (Longer than 2m);
2) As we discussed in the page of “Single Axis Welding Turntable”, the vertical revolving Welding turntable is used for welding short length parts, which forms complementary function with this Head and tail Welding Positioner;

3) For understanding on general picture and strong points, please visit thematic page of “Superiority of Wuxi JACK Welding Positioner”.

1. The Applicable Workpiece and Structure of Fixed Height Head and Tail Welding Positioner:

1) This kind of head and tail Welding Positioner is applicable for welding small cross section workpiece, with relative light weight. So, it is no need to raise welding turntable during working;
2) Both ends of working parts are joint with lateral sides of the welding turntable;
3) During working, the working parts and welding turntable revolve around the horizontal shaft connected between both sides of the head and tail Welding Positioner.

2. The Classification on Fixed Height Head and Tail Welding Positioner:

1) As you can check from the right hand photos, the fixed height head and tail Welding Positioner can be either splitting type, or integral type; The revolve of welding turntable can be either in motor drive, or hand turning;
2) The white color integral structure head and tail Welding Positioner is the overlapping product with Welding Fixture. The rotation of welding turntable is pushed by hand, and locked in angular position. Please check product Horizontal Revolving Welding Fixture type Welding Positioner with Double Connection;
3) The light green color head and tail Welding Positioner has splitting body. The revolve of working parts is driven with motor. Please check product Head and Tail Welding Positioner for Manual and Automatic Welding.

3. Technical Parameters of Fixed Height Head and Tail Welding Positioner:

These are tailor made welding turntable, of which technical parameters differ case by case.

1. The Applicable Workpiece and Structure of Head and Tail Lifting type Welding Positioner:

1) When the cross section of working parts become larger, and or welding points are distributed at different position, the head and tail Welding Positioner should have lifting function;
2) For smaller size head and tail lifting type Welding Positioner, it is usually has splitting structure, as shown in the top and bottom ones of left hand photos;
3) When the working parts grow higher and heavier, usually there is a solid horizontal beam connected between both ends of the head and tail Welding Positioner, serving as welding turntable, as you can check from the middle one of left hand photos;

4) Besides, the bottom one at left hand photos shows the head and tail Welding Positioner with moving side brackets. It is for working parts with wide range of length.

2. The Classification of Head and Tail Lifting type Welding Positioner:

In the description on structure of head and tail lifting type Welding Positioner as above, we have mentioned its classification somewhat. Here is the complement:
1) The three photos at left hand reflect the three sets of head and tail Welding Positioner with elevating stroke of 800mm, 3000mm, and 2500mm respectively;
2) The corresponding transmission are leadscrew, chains and sprocket. You can name it medium duty and heavy duty head and tail Welding Positioner respectively;
3) For detail, please check product Chuck Fixing Lifting type Welding Positioner with Double Table Top, and Head and Tail Lifting type Welding Positioner.

3. Technical Parameters of Head and Tail Lifting type Welding Positioner:

These are tailor made welding turntable, which technical parameters differ case by case.

1. The Applicable Workpiece and Structure of Head and Tail Revolving Rotating Lifting type Welding Positioner:

1) In practical application, such three axis head and tail Welding Positioner is usually heavy duty, for process large size, heavy weight, and complicated structure of working parts;
2) On the horizontal beam, there is piece of welding turntable, which can be turned 0°~360°;
3) In the working of such head and tail Welding Positioner, the 0°~360° revolving around horizontal axis, and 0°~360° rotation of welding turntable are all welding speed on working parts, which is controlled with inverter. Or, in strict condition, driven with servo motor;
4) For detail, please check product Three Degree of Freedom Head and Tail Welding Positioner, and Servo Drive Head and Tail Rotation Lifting type Welding Positioner.
