General Purpose Motor Drive Speed Control Weld Turning Table

1.       Specialty and Usage of Electric Welding Turning Table:

1)      Electric Weld Turning Table is a kind of simplified Welding Positioner. As you can find from attached photos, it removes tilting of Welding turntable from the standard single table top Welding Positioner, and keeps the infinite 0°~360° revolve of Weld turntable with speed control;

2)      In this way, this Electric Welding turntable makes workpiece revolving in horizontal surface of the Weld turntable, around vertical axis, or axis of certain fixed angle, for the purpose of Welding, Hard facing, or Cut of cylindrical parts;

3)      In this respect, this simplified Welding Positioner is a kind of general purpose Welding Turning Table, which has extensive practice in the industry.

2.       Put into Use of the Electric Welding Turning Table:

1)      This simplified one control axis Electric Welding Positioner can be used as a set of individual welding machine, which means works independently, or as a supplementary unit in a complete group of Welding Center, coordinating with other welding equipment, such as Welding Rotator, Welding Column and Boom, etc.;

2)      Main Motion units in the Electric Weld Turning Table:

a)       Revolving Electric Weld turntable is the execution mechanism of this one control axis Welding Positioner;

b)      The Welding turntable here has the same exterior and internal structure as that of the Single Table Top Welding Positioner: A set of slewing support is also used for driving the Welding Turntable into rotation;

c)       Same as the single worktable Welding Positioner, there are 6 pieces of T slots cut in the surface of the Weld Turning Table, for fitting and securing workpiece of various sizes and species; 

Single Axis Horizontal Welding Turning Table: (Fig.1)

d)      Special fixture is also necessary to be applied in this Electric Welding Turning Table to fix the workpiece.

3.       Technical Characteristics of Electric Weld Turning Table:

Technical description of this Weld Turning Table:

1)      Control Axis in the Welding Turning Table:

It has only one degree of freedom as the above mentioned;

2)      Speed Control in the Electric Welding turntable:

In most majority conditions the revolving speed of the Weld turntable, which is also welding speed of workpiece, is adjustable controlled with inverter, meeting the requirement of welding technology;

3)      Loading Capacity of the Electric Weld turntable:

a)       There are various of loading tonnage available with this series of variable speed one control axis Welding Positioner;

b)      The often used specifications are 2Ton, 3Ton, 5Ton, and 10Ton loading capacity of the Welding Turning Table. Higher than this specification should be classified as heavy duty Welding turntable. Currently in industry the max. loading tonnage of the Weld Turning Table is 50Ton.

4.       Deceleration Mechanism in the One Control Axis Welding Positioner:

1)      This variable speed Welding turntable usually has broad range of reduction ratio: It is usually kept at 330:1; 

Single Axis Horizontal Welding Turning Table: (Fig.2)

2)      For this reason, secondary deceleration is often introduced to this Electric Welding Turning Table. Please check the above picture: One side of the Welding turntable base bed is worm gear reducer, and the opposing side is cycloidal pin wheel reducer;

3)      With such combinational reduction unit adopted in the Electric Weld turntable, the ideal reduction ratio can be met in this One Control Axis Welding Positioner.

5.       Equipment Structure of the Electric Welding Turntable:

Also, as can be seen from the above picture, the motor and reducers are put at both sides of Electric Welding turntable base bed. Such kind of design has at least three advantages of:

1)      Maintain stable gravity center of the Welding Turning Table;

2)      Such symmetrical deployment of the heavy duty motor and reducer makes good appearance of the entire set of Electric Weld Turning Table;

3)      The entire unit of driving and transmission system will not extend beyond base bed of the Electric Welding turntable. In this sense, it saves land and space occupation in the workshop.

6.       Durability of the Electric Welding Turning Table:

Besides the conductive device which is an indispensable unit equipped into all kinds of Welding Positioner, this Electric Welding Turning Table also shares the common strong point of good Grounding, Water connection (if necessary), Gas connection (if necessary), Heat conduction and Ventilation.

7.       Technical Parameters of Electric Welding Turning Table:
