1) If dividing the product family of Weld Positioner into two groups of routine type (The HB series Single Work Table as introduced in the previous product sections) and particular type, this L type Weld Positioner is the first group of products which should to be mentioned;
2) As an important branch, the LBS series L type Welding Positioner is widely used in Vehicle Industry, Construction Machinery Industry, and Engineering Machinery Industry, for welding long length structure members which are used as sub assemblies during vehicle construction;
a) There are many variations in terms of degree of freedom, mechanical structure, quantity of Welding Turning Table in the sub group of LBS series products, depending on specific application demand from customers;
b) This product section is just the starting point of such Welding Turning Table. Due to its stationary linear motion along Z axis, which means, height of L arm and workpiece can not be changed during working period, there is certain restrictions to function of its Welding Turning Table. So, many more types of complicated three motion axis L type Welding Positioner are applied in practical field.
a) Overall Structure: The L type Welding Positioner has different mechanical structure, and hence appearance at first glance compared with the Single Work Table equipment. Sometimes it is also called as "I type", depending on how you view it;
b) Tilt of Workpiece: The L type Welding Positioner does not have working mode of tilting its Welding Turning Table, as in the case of Single Work Table models, because of no need; Instead, the L arm can be revolved 0°~360° in vertical plane;
a) Both types of the equipment have its Welding Turning Table capable of 0°~360° infinite rotation, and the corresponding revolving linear speed is adjustable with inverter;
b) As can be found from the above discussion, the L type Welding Positioner also has 2 control axes, or, in other words, 2 degrees of freedom.
Customer running site of Wuxi JACK LBS12 (1.2 ton loading capacity) : (Fig.1)
As shown in the above photo, set of typical LBS model L type Welding Positioner is composed of:
1) Mechanical Machine Bed:
This is the main trunk, for holding the entire set of the Welding Positioning Equipment as a solid base;
2) Machine Column:
This is for guiding the vertical plane revolve of the L arm, during working period of fabrication
3) L Arm:
a) This is where this specific type of Weld Positioner got its name from. It is used for leading its Welding Turning Table and workpiece rotation and revolve in the range of 0°~360°;
b) There is counterweight at its top (black color), to offset weight of Welding Turning Table and workpiece, maintaining balance on the entire set of welding equipment during running;
a) Same as the HB models Single Work Table double motion axis Welding Positioner, the Welding Turning Table here is for fitting workpiece on its top;
b) Its revolve linear velocity is adjustable with A.C. inverter, and displayed with digital meter. In this sense, it is a variable speed Weld Positioner, or Weld Positioner with digital display, whatever.
