CNC And Servo Drive Precise Welding Turning Table

1. Outline on Servo Drive Rotary Welding Table:

1) Working Nature of the Servo Drive Welding Turntable:

a) The precise welding equipment discussed in this product section, is the high precision version of the ordinary motor drive Weld Turning Table discussed in the last product section;

b) For the purpose of turning workpiece to achieve high precision angular position control, it can be viewed as a plain type Servo Drive Welding Positioner;

2) Application of Servo Drive Weld turntable:

a) Where Used: This precise control welding equipment is generally used at robot welding, or precision welding station, in the application field of Aerospace, Military industry units;

b) Related Equipment: Very often this plain type servo drive welding equipment works with other welding machine tool, such as special made welding machine, or pipe assembly and welding Machine, or works as a cell in tailor made welding center, etc.;

3) Working Principle of Servo Drive Weld Turning Table:

a) This series of precise control servo drive single work axis Weld Turning Table shares the similar application and usage, structure, degree of freedom as the previous product section of ordinary motor drive Weld turntable, which we will not repeat here again. If you are interested, please check the previous one product;

b) Here in this product section, let us explore the most salient difference, or distinction of this Servo Drive welding equipment turntable.

2. Transmission and Precision Attained in Servo Drive Rotary Welding Table:

1) Transmission of Servo Drive Welding Turntable:

a) The planetary gear reducer adopted here has back clearance of 16 arc minute;

b) Fit with the pinion of m=6/z1=16, the final clearance after reduction by gear equals to [16 Arc Minute/(193/16)]= 0.33 Arc Minute;

c) It is nearly imperceptible to have feeling on such small clearance during running of the Servo Drive Weld Turning Table;

d) And converted to circumference of 2m diameter weld turntable, the arc length of external circle is（2000*3.14）/（360*60*1.8）=0.16mm;

e) This attains the target of clearance elimination in the drive and transmission of this series of precise managed Servo Drive Rotary Welding Table;

2) How to Attain High Precision in Plain type Servo Drive Welding Positioner:

a) By means of a complete cycle of rigorously managed process technology on production of the servo drive welding machine tool;

b) Including precise machining and assembly process of its components and sub assemblies;

c) As well as outsourced control and drive units of high precision: Servo motor, high precision slewing support (Or called round gear), high precision planetary gear reducer;

3) Support Unit in Servo Drive Welding Turntable:

a) As the item 2 mentioned, for this precise Servo Drive Weld Turning Table, ordinary slewing support (Rr called round gear) can not meet the demand on high standard precision management, it should be precise type;

b) For example, for the 2,000mm diameter Servo Drive Weld turntable, precise slewing support of QW1000.25 has big gear of m=6, g2=193, which can have loading capacity up to 30 Ton, together with very good stress condition.

3. Control System of Servo Drive Rotary Welding Table:

1) This product series of servo drive welding machine tool will be equipped with precise detecting elements, such as proximity switch, making the workpiece stopped automatically at 90° or 180°;

2) This Servo Drive Weld Turning Table can be either have its individual control system, control board, operating pendant to have capability on working independently, or just leave an open RS232 interface, for the ease of future connection with external controllers, such as PLC (Programmable logic controller) and its special module, industrial computer.

4. Technical Parameters of Servo Drive Rotary Welding Table:

This series of servo drive welding machine tool is personalized tailor made. So, its specific technical specifications depend on actual application case.
