3)       Fixation of workpieces onto the Rotary Welding Table is secure and firm, without damage on the workpieces during loading/ unloading/ welding operation;

4)       Operation and Service is convenient and user friendly, this includes ergonomics height of the Servo Drive Welding Turntable; Loading & Unloading/ Secure & Release of the workpieces, etc.;

5)       Logistics: Integral Design of the Single Axis Welding Positioner makes it with compact size and solid structure, which is easy for transportation, relocation and placement;

6)       Accommodating Harsh Working Environment: The servo motor and servo driver have high degree of IP protection. So are other electric control elements, and mechanical system of the Servo Drive Rotary Welding Table.

B.       Structure and Main Units of the STB50 Servo Drive Turning Table Positioner:

1.Structure: The overall appearance of the assembled Servo Drive Welding Turntable is shown in below: (Fig.3)

2.       Check from the above photo, the Servo Drive Turning Table Positioner has 5 Main Units of:

1)       Round shape mechanical base frame, for mounting the entire piece of Rotary Welding Table, and customer prepared water channel;

2)       Rotary Welding Table, which is core unit of the Single Axis Welding Positioner;

3)       Slew Bearing: The central unit for rotation. It determines smoothness and precision of Rotary Welding Table rotation;

4)       3 Jaw Chuck Adjustable Welding Fixture: It is installed onto top surface of the Welding Turntable, for clamping workpieces perfectly in place firmly during fabrication;

5)       Driving and Transmission Unit: This includes: Cables, Servo Driver and Motor, control and operating elements, as well as motor reducer.

C.       Tailor Made Welding Fixture Equipped with the STB50 Servo Drive Welding Turntable:

1.       Close up view on the 3 Jaw chuck Welding Fixture: (Fig.4)

2.       Structure: As can be found from the above photo, this Welding Fixture has 3 pieces of branches, officially named as jaw chucks, with 120° apart from each other;

3.       Way of Fixing Workpieces onto the 3 Jaw Chuck Welding Fixture:

1)       There is a long length slot in each of the chuck branch;

2)       There is a row of claws in each of the slot middle line;

3)       These claws and slots are used for positioning different sizes of workpieces onto Welding Fixture in accurate position, which in turn onto Rotary Welding Table;

4)       The exact location of these claws can be adjusted, based on diameter of the workpiece;

5)       Final fixation of the workpiece onto the Servo Drive Turning Table Positioner is by means of a long piece rod, as shown in the above photo;

4.       Anti-Corrosion: Made from Stainless Steel, the entire piece of Welding Fixture has been treated with anti-rust performance.

D.      Technical Specialties and Tolerances of the STB50 Servo Drive Single Axis Welding Positioner:

1.       Working Principle of the Servo Drive Turning Table Positioner:

1)       Guide: Slew bearing is installed beneath Welding Turntable for rotation transmission;

2)       Drive: By means of servo motor and driver, and by way of gear couples, the Servo Drive Welding Turntable is driven into revolve;

3)       Transmission: Revolve of the Rotary Welding Table is transmitted with high precision planar reducer;

2.       Revolve Tolerance of the Servo Drive Rotary Welding Table:

1)       When the servo motor works under the rated revolutionary speed of 3000rpm, the corresponding revolve speed of the Welding Turntable is 6 rpm;

2)       The repetitive locating precision of the Rotary Welding Table is less than ±0.1°;

3.       Mechanical System Tolerance in the Single Axis Welding Positioner:

1)       Diameter of the Rotary Welding Table is Φ1800mm, for fixing the max. diameter workpieces of Φ1700mm;

2)       Made from Stainless Steel, surface of the Welding Turntable is precisely machined and heat treated, with flatness controlled within the tolerance of ±0.5mm;
