This type of manual control Lifting type Welding Positioner is derived from the preceding sub group of HB series Single Table Top Welding Positioner, it is the upgraded version product configured with elevating function of the Weld Turning Table;
a) As has been discussed from the previous sections of Weld Positioner introduction, the typical Single Work Table Welding Positioner have 2 axes of motion: Weld Turning Table revolving in the range of, and 0°~120° tilting. Now, with the capacity of adjustable height of Weld Turning Table in the Welding Positioner, the additional Z axis along vertical direction can be got and manipulated;
b) So, these sub group of products can be described as Single Table Top Welding Positioner, which denotes features of this specie of Rotary Welding Positioner more comprehensively.
a) Sometimes the space of the Weld Turning Table in the Welding Positioner along vertical direction is not sufficient to manipulate revolving and or tilting 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 the Welding Positioner;
a) Tonnage of such kind of elevating style Single Table Top Welding Positioner is restricted to 3Ton 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 in the Weld Positioner, which involves control of Weld Turning Table in vertical Z axis, other structure of elevating type Welding Positioner should be applied for customer, which will be introduced in the subsequent product sections of “L type Hydraulic Elevating and Electric Revolving Welding Positioner”.
a) From attached pictures we can see that height adjustment of the Weld Turning Table in the Welding Positioner 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;
b) By changing the fitting holes grade of the mounting bolts, height of Weld Turning Table in the Weld Positioner can be altered accordingly;
a) First loosen the fitting bolts of the 2 columns of the Weld Turning Table;
b) Hoist the Weld Turning Table away from equipment base of the Lifting type Welding Positioner;
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 is changed to another grade for this Small Welding Positioner;
e) From this, we can see it is a manual adjusting Elevating Welding Positioner, to be more specifically.
a) Synonym of this group of products: Single Table Top Elevating Weld Positioner, or Single Work Table Elevating Weld Positioner;
b) From the above description, we can see that the modulation manner in this Lifting type Light duty Welding Positioner is similar to HLK series Bolt Adjusting Welding Rotator. If you are interested, please check.
