1. The Application Scope of Head and Tail Welding Positioner:
1) This is one of the main branches of product family Weld Positioner, in addition to the HB series Two Motion Axis Single Welding Table, and LBS models Three Axis elevation function L type Weld Positioner;
2) Head and Tail Weld Positioner is another frequently used Welding turntable in Construction Machinery and Engineering Machinery facilities, often is found to be especially useful for welding components for making sub assembly, such as boom, frame carriage of excavator, etc. As you can find from the attached photos.

2. Technical Characteristics of Head and Tail Welding Positioner:
1) One Degree of Freedom:
There are double sets of rotating work table in one set of the Head and Tail Weld Positioner. The two Welding turntable at both ends have one degree of freedom only: The 0°~360° infinite revolve;
2) Function of Both Ends Welding Turntable:
a) Similar to the previous product of Fixture type Weld Positioner, the both ends of Welding turntable here are reduced to two pieces of upright erected holding brackets;
b) The workpiece is joint with both ends of the Head Tail Welding turntable: One side connected with the “Head” of the workpiece (Head stock), and the other side with “tail”(Tail stock), this is where the product name of “Head and Tail Welding Positioner” got from;
c) So, the workpiece is the bridging unit with the both ends of Welding turntable
3) The Integral Structure of the Head and Tail Welding Positioner:
a) This welding positioning equipment has splitting structure;
b) There is guiding rails in the ground for changing position of both ends Welding turntable, so that different lengths of workpieces within its specification can be secured into both ends double columns Welding turntable;
Movable tail stock with floor rails: (Fig.2)
3. Put into Use of Head and Tail Welding Positioner:
1) Reliably Fitting Workpiece into Head and Tail Welding Positioning Equipment:
a) The two Welding turntable at both ends are equipped with chucks on it, for the purpose of fitting workpiece;
Head stock and tail stock: (Fig.3)
b) With the workpiece installed between the head and tail two sets of Welding turntable, operator can perform welding operation on the workpiece;
c) The workpiece is at “lying down” position in the Head and Tail Welding Positioner, or more accurately described as “hanging in the air in flat position”;
d) Such kind of design forms operating station of open structure and low height in the welding equipment, which is easy, safe, and comfortable for doing manual welding operation;

2) Control and Adjustment in Head and Tail Welding Positioner:
a) The workpiece revolve is motor reducer drive. Revolve linear speed can be either constant or adjustable, depending on customer demand;
b) One side of the Welding turntable is fixed type, with the above mentioned motor reducer installed, serving as driving side, tail stock;
c) The opposing side of the Welding turntable can be pushed or pulled along the ground rail forward and backward, accommodating changeable length of workpiece;
3) Operating the Head and Tail Welding Positioner:
a) With single control motion axis (Workpiece horizontal revolve) in the welding equipment, circumferential welding, longitudinal welding can be fulfilled with manual job;
b) Other operations such as inspection, grounding, repair weld, etc. can be also be carried out;
c) Operation is carried out with buttons integrated on Welding turntable;

4. Technical Specifications of Head and Tail Welding Positioner:
This horizontal type Head and Tail Welding Positioning Equipment is custom made. So, its technical parameters differ on specific case.
