General Purpose Motor Drive Speed Control Weld Turning Table

1.  Specialty and Usage of Electric Welding Turning Table:

1) Technical Feature: This round table welding equipment is a kind of simplified single axis Welding Positioner. As you can find from attached photos, it removes tilting of Welding turntable and hence workpiece from the standard single table top Welding Positioner, and keeps the infinite 0° ~ 360° revolve with viable speed control and display;

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

3) Application: Thanks to its "simple" structure and flexible accommodation, this simplified Welding Positioner is a kind of general purpose equipment, which has extensive practice in the industry.

2. Put into Use of Electric Welding Turning Table:

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

2) Main Motion Units in Electric Weld Turning Table:

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

b) The Welding turntable here has the same exterior and internal structure as that of the conventional two axis models: A set of slewing support is also used for driving workpiece into infinite rotation;

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

Worktable and its cut 6 pieces of T slots: (Fig.1)

d) Assistant Function Unit: Special design welding fixture is also necessary to be applied here to fix the workpiece.

3. Technical Characteristics of Electric Weld Turning Table:

Technical description of this welding equipment:

1) Control Axis: It has only one degree of freedom for workpiece revolve, as the above mentioned;

2) Welding Speed Control:

In most majority conditions the revolve speed of the Weld turntable, which is also welding speed on workpiece, is adjustable controlled with A.C. inverter, meeting the requirement of welding technology;

3) Loading Capacity of 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 2 Ton, 3 Ton, 5 Ton, and 10 Ton loading capacity. Heavier than this specification should be classified as heavy duty models. Currently in industry the max. loading tonnage is 50 Ton.

4. Deceleration Mechanism in 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; 

Motor reducer base of single axis equipment: (Fig.2)

2) For this reason, secondary deceleration is often introduced here 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, the ideal reduction ratio can be acquired.

5. Equipment Mechanical Structure of 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 entire set of Welding Turning Table and workpiece during welding operation;

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

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

6. Durability of Electric Welding Turning Table:

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