A. Brief on Application and Composition of High Precision Servo Drive Rotary Table:
1. Customers: The 2 Chinese clients are located at Qingdao and Wuhan cities, on Boiler/ Confidential Industry respectively;
2. Purpose: The 2 Customers Purchase Turn Table for Testing and Welding Use Respectively:
1) For Testing Use of Rotary Table:
a) Overall Arrangement: The customer works in confidential field. The 3 Jaw Chuck are assembled onto top surface of Rotary Table. The cylindrical workpiece will be plugged onto center of the 3 Jaw Chuck, with its wall perpendicular to top surface of the Rotary Table;
b) Integrated Working Group: There is a set of robot being located alongside the Turn Table, with monitoring system and graphic indicator integrated. The articulated arm of robot touches with wall of cylindrical workpiece. And by means of Turn Table rotation, the peripheral wall of cylindrical workpiece will be tested real time through testing system of robot, and demonstrated into graphic monitor of robot;
c) This composes the entire working unison of High Precision Servo Drive Turn Table, and is applied in confidential use;
d) Appearance of 3 Jaw Chuck before assembled onto Turn Table: (Fig.1)
2) For Welding Use with Welding Turntable:
a) This is more common seen application way of Welding Turntable. It is horizontal orientated, single axis control (Z axis, revolving);
b) Workpiece Secure: Before welding operation, workpiece will be put onto top surface of Welding Turntable, and fixed tightly by means of welding fixture;
c) Welding Form: Then, with rotation of Rotary Table, the workpiece can be welded under different smoothly adjustable welding velocity;
d) The revolving speed of Welding Turntable is by means of servo drive, which can acquire wider scope of welding speed;
e) Appearance of Servo Drive Welding Turntable: (Fig.2)
B. The Structure and Usage of 3 Jaw Chuck with Assembled onto Turn Table:
1. Work Nature: 3 Jaw Chuck is a kind of high precision fixture. It can be used in various types of machines and equipment, serving as workpiece fixture: Turn Table here, or CNC Pipe Cutting Machine, or Pipe Flange Circumferential Welding Machine, etc.;
2. Material: As shown in the photo, 3 Jaw Chuck is made of stainless steel, which has characteristics of: Heat resistance/ water resistance / no deformation after long time use. These are all prerequisite for satisfactory confidential application;
3. Size and Machining: Here in this business case, the 3 Jaw Chuck has diameter of Φ1,600mm. Production Technology: The entire piece of the chuck is machined in the sequence of: First cut with lathe, then machined with Milling Machine, then holes drilled with drilling machine;
4. Assembly of 3 Jaw Chuck onto Rotary Table:
1) Overall appearance of 3 Jaw Chuck after being assembled onto Turn Table: (Fig.3)
2) Operating Way: As shown in the above photo, the 3 Jaw Chuck is installed onto top surface of Turn Table. In other words, during testing period, it is kept fixed, instead of rotating along with Turn Table;
3) Fitting on Workpiece Varying Diameters in 3 Jaw Chuck:
a) Copper Blocks: There is row of copper block along each jaw of the 3 Jaw Chuck. These copper blocks are arranged one by one tightly, forming an array, and fit into positioning slot of each jaw;
b) Aim: This is for fitting on different diameters of cylindrical workpieces, which will be secured onto the 3 Jaw Chuck. As shown in the photo, there is a small turning roll assembled onto the 3 arrays of copper blocks, this is another smaller fixture; For testing operation, the cylindrical workpiece will snapped onto this turning roll;
c) Operating Style: Then, along with rotation of Turn Table and 3 Jaw Chuck, the workpiece will go into revolve also. And by means of different sizes of turning roll snapped onto copper blocks, different diameters of cylindrical workpiece can be tested here reliably on Turn Table and 3 Jaw Chuck;
4) Hoist: Also can be observed from the photo, there are 4 pieces of lifting eyes on top surface of Rotary Table, distributed in symmetry at both sides of the Turn Table circle center. The entire piece of equipment can be hoisted reliably.
C. Technical View on High Precision Servo Drive Welding Turntable:
1. Guarantee on High Precision: For fulfilling requirement on high precision management on position, both customers asked for servo motor, as driving source of their Rotary Table rotation;
2. Technical Parameters of High Precision Servo Drive Welding Turntable:
