1. The Purpose of Servo Drive High Precision Rotary Welding Positioner:
1) Characteristic: The horizontal lying double Weld Turning Table Servo Welding Positioner is the high end model product of such structured Weld Positioning Equipment;
2) Application Background: As discussed in the product section of “L type Elevating and Revolving Servo Drive Welding Positioner”, nowadays there is trend on in welding field that, robot and automatic welding gradually replacing manual welding whenever possible, especially in facilities of large volume batch production in stream line;
3) This is the reason why in nearly every sub group of welding positioner product, from the beginning one of single welding table models, to L type lifting models, to this double work table models, are all have 2 species of controlling and driving mode: The conventional configuration, of which workpiece revolve and tilt is driven with ordinary motor reducer or hydraulic system, and High Precision models, of which workpiece position manipulation is with servo motor drive and encoder management.
2. Technical Outline on Servo Drive High Precision Rotary Welding Positioner:
So, the Numerical control and Servo Drive welding positioning equipment (whatever its structure) can be featured as:
1) Mechanical System in Servo Drive High Precision Weld Positioning Equipment:
a) These High Precision Weld Turning Table have the similar mechanical structure as that of the conventional type equipment models;
b) To fully guarantee on the high precision performance of welding positioning, its machining process are in stricter sense and higher standard;
2) Workpiece Position Precision Control in Servo Drive High Precision Welding Positioner:
The transmission unit in Servo Welding Positioner delivers much more higher degree of precision:
a) Tolerance of ±0.05° in Weld Turning Table and workpiece 0° ~ 360° revolve;
b) And tolerance of ±0.1mm for linear motion and point control under the condition of additional degree of freedom introduced: Workpiece elevation, and or horizontal displacement;
c) Servo motor is a must for these high precision models products. This is also the reason Servo Drive Welding Positioner is confined to light and medium duty use;
3) Control System in Servo Drive High Precision Welding Positioner:
a) The control system of these High Precision Weld Positioning Equipment is in the form of servo encoder system, with negative feedback closed loop circuit;
b) There is interface left open for communicating with external controller, such as Robot, CNC, PLC, Industrial Computer, etc., thus composing into more complicated and advanced welding group;
4) Transmission System in Servo Drive High Precision Welding Positioner:
a) Significance: The critical point in a set of servo drive Welding Positioner, either it has double or single Weld Turning Table, in the form of round shape or lifting L type, is its transmission unit;
b) Transmission unit of all the servo drive Weld Turning Table have function of Clearance Eliminating: Which means, that with the adoption of precision planetary motor reducer, as well as two motor reducers driving both sides of the gear, the high precision Welding Positioner drives workpiece into motion without any clearance.
3. Application of Servo Drive High Precision Rotary Welding Positioner:
1) Where Used: In the manufacture field of welding, the Servo Drive Welding Positioner is more applied in robot welding than connected with other types of controllers: Robot accounts for over 80%~90% application of these welding positioning equipment;
2) Diversified Structure of Mechanical System in Servo Drive Rotary Welding Positioner:
a) For this sub group of product, its concrete structure of equipment mechanical structure can have as many variations as conventional type Welding Positioner: Welding Fixture type, Head and Tail Welding Positioner, Elevating type … For which we will introduce in the later on subsequent product sections;
b) The choice on specific design comes from customer preference and practical application scenarios;
3) Working together with robot, this kind of servo drive High Precision Welding Positioner is the most often used type of demonstration equipment in all kinds of Trade Fair and Exhibition in Welding Technology and Equipment Industry, to show the latest development of welding technique and strength of the company.
4. Technical Parameters of Servo Drive High Precision Welding Positioner:
This is also personalized tailor made Weld Positioning Equipment and Weld Turning Table. So, its detailed technical specification depends on specific application case.
