Three Degree of Freedom Head And Tail Welding Positioner

1. The Three Control Axis in Elevating type Head and Tail Welding Positioner:

This model is intricate version in product family of Weld Positioner. The product name suggests workpiece to be welded has three degrees of freedom:

1) The 0°~ 360° clockwise and counterclockwise infinite revolve of Rotary Welding Table and workpiece, along the horizontal axis of the equipment;

2) The up and down movement of Rotary Welding Table and workpiece along headstock and tailstock. These two control axis are same as that of the “Head and Tail Elevating type Welding Positioner” discussed before;

3) On that basis, the 3^rd degree of freedom is added: That on the horizontal beam connecting the two side columns headstock and tailstock (or table top, or machine beds), at its middle point, there is a piece of pallet, or Rotary Welding Table installed. Workpiece is secured here, and can be rotated infinitely 0°~ 360° in both CW and CCW directions. This gives more available manipulation on best orientation of workpiece, during welding period: 

Workpiece fixture and rotate: (Fig.1)

2. Usage of Three Control Axis Lifting and Revolving Head and Tail Welding Positioner:

1) With the added degree of freedom of workpiece rotation on the Rotary Welding Table, its orientation can be managed in more refined precise manner;

2) Such double columns Welding Positioner is especially useful for welding workpiece with many seams on it, in complicated design of arrangement.

3. Nomination of the Lifting and Revolving Head and Tail Welding Positioner:

A confusion on name of this complicated welding positioning equipment may arise:

1) That in the product sections of “Single Table Top Weld Positioner”, which has two control axis of Rotary Welding Table revolve and tilt,

a) Revolve” refers to Rotary Welding Table and workpiece turning around motion within the range of 0°~ 360°;

Design sketch on conventional two degree of freedom (Revolve and tilt): (Fig.2,3)

b) And “Tilting” refers to Rotary Welding Table and workpiece swing around motion within the scope of 0°~ 120°;

2) In Head and Tail Lifting and Revolving Welding Positioner:

a) Both the revolve of workpiece around the horizontal axis joining the two columns headstock and tailstock (The orange color frame in below photo), and the rotation of workpiece on its Rotary Welding Table on the beam joining the two columns (The yellow color frame in below photo), are all turning around movement of 0°~ 360°;

Headstock and tailstock (Orange color square frame): (Fig.4)

b) In terms of revolving motion itself, there is no difference; But the orientation of control axis, or degree of freedom, as can be observed from the above photo, is different;

c) To differentiate the two turning round motions, we use the word “Revolve” and “Rotation” respectively to make distinction. In this respect, this welding positioning equipment should be named Head and Tail Lifting and Revolving Welding Positioner with Rotary Welding Table.

4. Structure of the Lifting and Revolving Head and Tail Welding Positioner:

1) As can be observed from attached photos, in this Elevating type Welding Positioner, a long and strong piece of horizontal beam is installed joining the two sets of erecting columns headstock and tailstock (machine beds), serving as revolving shaft and holding unit of the workpiece Rotary Welding Table;

Revolving shaft and holding unit of workpiece: (Fig.5)

2) This is the most conspicuous distinguish between this Lifting and Revolving Head and Tail Welding Positioner, with the previous product, that usually there is no physical connection between the two side columns headstock and tailstock, or machine beds. Instead, during working period, only the workpiece joins the two side columns;

5. Technical Specialties of Lifting and Revolving Head and Tail Welding Positioner:

1) Design of Rotary Welding Table on the horizontal beam is convenient for fitting jigs and fixtures in short time, and applicable for various kinds of workpiece;

2) The horizontal beam revolves around the axis connecting the two columns headstock and tailstock (machine beds), in constant speed, or required welding velocity;

3) The horizontal beam moves up and down along the two columns (machine beds) in constant speed;

4) The workpiece rotates on its Rotary Welding Table in adjustable speed of welding.

6. Technical Parameters of Lifting and Revolving Head and Tail Welding Positioner:

1) In all, as at the beginning of this product section said, this elevating type welding positioning equipment is sophisticated machine tool for fulfilling on complicated manual and automatic welding operation;

2) Due to its tailor made, its technical specifications vary from case to case.
