Single Table Top Manual Vertical Elevating Welding Positioner

1.  What is Manual Adjustment Lifting type Welding Positioner?

1) Origin:

This type of manual control lifting type equipment is derived from the conventional group of HB series Single Table Top Welding Positioner, it is the upgraded version product configured with elevating function of Weld Turning Table and workpieces;

2) Working Capability of Lifting type Welding Positioner:

a) The 3rd Degree of Freedom:  As has been discussed from the product section introduction, the typical Single Work Table Welding Positioner have 2 axes of motion: Weld Turning Table revolve in the range of 0°~360°, and 0°~120° tilt. Now, with the capacity of adjustable height of Weld Turning Table and hence workpieces, the additional Z axis along vertical direction can be got and manipulated;

b) So, these sub group of products can be described as three axis Welding Positioner, which greatly extends its applicable size (Especially length) of workpieces.

2. Application and Applicable Tonnage of Manual Adjustment Lifting type Welding Positioner:

1)  Application of Manual Adjusting Elevating Welding Positioner:

a)  Sometimes the space of the Weld Turning Table along vertical direction is not sufficient to manipulate revolve and or tilt of workpiece, as in the case of large size structure member with relative light weight;

b)  Under such conditions, to have an adjustable Weld Turning Table in height is very useful for proper running of welding operation;

2) Applicable Tonnage of Manual Elevating Welding Positioner:

a) Tonnage of such kind of elevating style welding positioning equipment is restricted to 3 Ton and less loading capacity of the Weld Turning Table. In other words, only Light duty Welding Positioner is suitable for being made into such structure of manual vertical adjustment working mode;

b) For welding heavier and bigger size of workpiece, which involves control of Weld Turning Table in vertical Z axis, other structure of elevating type welding positioning equipment should be applied for customer, which will be introduced in the subsequent product sections of “L type Hydraulic Elevating and Electric Revolving Welding Positioner”.

3. Way of Adjustment on Weld Turning Table Elevation in Manual Lifting Light duty Welding Positioner:

1) How to Change Height of Workpiece in Welding Positioner?

a) From attached pictures we can see that height adjustment of the Weld Turning Table and workpiece is made by hand: There are arrays of mounting holes (Often 4~ 5 holes in a set of Welding Positioner) on each of the 2 pieces of vertical columns of the machine frame; 

Different grades of bolts for adjusting height of workpiece: (Fig.1)

b)  By changing the fitting holes grade of the mounting bolts, height of Weld Turning Table and workpieces can be altered accordingly;

2) Process Steps of Vertical Adjusting Weld Turning Table in Welding Positioner:

a) First loosen the fitting bolts of the 2 columns of the Weld Turning Table;

b) Hoist the Weld Turning Table away from equipment mechanical base;

c) Lower down the Weld Turning Table and assemble it into the new grades of fitting holes in the 2 columns;

d) In this way, height of the Weld Turning Table and workpiece is changed to another grade;

e) From this, we can see it is a manual adjusting Elevating Welding Positioner, to be more specifically.
