The Structure, Working Mode, Application of Head and Tail Welding Positioner

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;

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;

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.

The Good Points of Wuxi JACK Rotary Welding Positioner

1. This is a series topic covering all aspect of Wuxi JACK product: Performance, quality, operation, cost, productivity, etc. We spread this topic in this page of “Head and Tail Welding Positioner”, as well as the related pages on the same product group of Welding Turntable: Two Axis Welding Positioner, Three Axis Welding Positioner, Single Axis Welding Turntable, Servo Drive Welding Positioner, and Special Made Welding Positioner;
2. Here we discuss on the multiple flexible realization of Welding turntable elevation in Rotary Welding Positioner, which is critical for normal running of Head and Tail Welding Positioner.

Multiple Flexible Way of Elevation on Welding Turntable in Welding Positioner:

 

How to Find the Most Applicable Way of Elevation and other Motion Control on Welding Turntable in Welding Positioner?

 
 

1. The Importance of Welding Turntable Elevation in Welding Positioner:

Elevation of Welding turntable and workpiece is the third degree of freedom in working of Rotary Welding Positioner, which is very useful for welding large height or big size working parts;

 

2. In the design on various types of Welding Positioner at Wuxi JACK, proper and flexibility is the guideline on how to realize elevation of Welding Turntable:

1) As we discussed in the page “Three Axis Welding Positioner”, Wuxi JACK adopts the safest and the most reliable way of hydraulic drive elevation for Welding turntable in all our L Lifting type Welding Positioner;
2) Besides, as you can find from the above photos, in large scale Head and Tail Welding Positioner, especially lifting stroke above 2m, chain and sprocket is proper way of driving and transmission to guarantee both sufficient holding force and elevating stroke, making reliable running of the Welding Turntable;
3) Meanwhile, under the precondition of safe operation, eligible welding and convenient job, we always explore the most applicable way of motion control in our products, including welding turntable elevation in Welding Positioner. Taking the manual Lifting type Welding Positioner in the above photo as example, you can find its up and down of welding turntable is realized by means of fitting into different grades of mounting bolts. This may remind you of the HLK Bolt Adjusting Welding Rotator. Definitely, the two products have similar way of adjustment on fitting for changed workpiece size;
4) For more detail, please check the product introduction of Single Table Top Manual Vertical Lifting type Welding Positioner, and Double Table Top Lifting and Rotation Heavy duty Welding Positioner.

The Subdivision on Head and Tail Welding Positioner

Here we divide the head and tail Welding Positioner into three branches of:
1. Single Axis Horizontal Revolving Fixed Height Welding Positioner;
2. Double Axis Horizontal Revolving Lifting type Welding Positioner;
3. Three Axis Horizontal Revolving, Rotating Lifting type Welding Positioner

Let us review the above three kinds of head and tail Welding Positioner one by one.
