The Significance of High Precision Positioner Control on Servo Drive Welding Positioner
1. Application Background of Servo Drive: Welding Positioner has extensive application across various manufacturing industries, especially Construction Machinery and Vehicle industries, involving fabricating on various structure members and complicated working parts. At some scenarios, the accurate angular position control in Rotary Weld Turntable has very high standard requirement, which entails the introduction of Servo Drive Welding Positioner;
2. Positioning Enforcement Units: Servo motor and servo controller are not the only necessary measures to guarantee on high standard accuracy of Rotary Weld Turntable. As execution unit, the transmission and mechanical system of servo drive Welding Positioner also plays critical role on making sure its strict sense of accurate angular positioning manipulation;
1) Wuxi JACK Achievement: We have designed and produced numerous precise servo drive Welding Positioner for customers, not only in the sub group of Single Axis Weld Turntable, but also Double Axis Welding Positioner, L type Welding Positioner, etc.;
2) As you can check from the above 4 photos, in Wuxi JACK servo drive High Precision Welding Positioner, the transmission unit/ mechanical body/ welding fixture… of the welding equipment are all special made high level ones, for guaranteeing on high standard performance. The transmission on Weld Turntable revolve and tilt are clearance eliminating type;
3) Positioning Precision Tolerance: The angular position accuracy in servo drive Welding Positioner for Weld Turntable of both 0°~360° revolving and 0°~110° tilting can be controlled within the tolerance of ±0.02°.
1. Two Axis 2 Ton/ 3 Ton Loading Capacity Weld Turntable Servo Drive Welding Positioner;
2. Single Axis 10 Ton Loading Capacity Servo Drive Weld Turntable;
3. Three to Four Axis Servo Drive Head and Tail High Precision Welding Positioner
1) The Servo Drive Welding Positioner at right hand photos are for confidential military use;
2) Positioning Precision Management: Generally speaking, when for fabricating on small to medium size and weight working parts of complicated structures,
a) When angular position control should be maintained within the precision level of ±0.02° ~ ±0.05°;
b) Or linear working motion should be kept within the precision tolerance of ±0.01mm;
c) When welding speed involves wider adjustable range, such as 20 times instead of 10 times with A.C. inverter...
Two axis servo drive Welding Positioner should be put into use.
1) Electric Control and Transmission: The 0°~360° revolve and 0°~120° tilt of Weld Turntable are driven with servo motor, detected with encoder, controlled with special model of PLC module or CNC controller, and transmitted with special made planetary reducer, which has double structure for clearance remove;
2) Mechanical Strength: The box structure mechanical body increases rigidity and strength of the servo drive High Precision Welding Positioner;
3) Loading Capacity: The servo drive Weld Turntable in the right hand photos have 3 Ton and 2 Ton loading tonnage respectively;
4) Welding Fixture for Workpiece Secure: Usually ingenious design delicate welding fixtures are used to firmly clamp workpiece onto Weld Turntable, as you can check from the right hand photos.
1) Max. Loading Capacity: 30 Ton, which covers fairly wide application of working parts;
2) The core mechanical working unit of the high precision welding equipment: Slewing support is precisely machined and special made;
3) Periphery Working Units: For its commissioning process at Wuxi JACK facility and customer site, we use CNC controller for managing on rotating of servo drive Weld Turntable; When works at customer site, laptop computer or CNC controller is used to monitor and trace on welding operation, with robot as welding equipment of the station.
1. Where Used: This is applied in robot working station, laser welding, special welding, or any other types of high precision automatic welding;
2. Control Axis: By means of robot control system and mechanical execution unit, the degree of freedom for welding can be up to 4~ 7 degree of freedom or more;
3. Technical Characteristic: The servo drive in Head and Tail Welding Positioner is on 0° ~ 360° revolve and 0° ~ 360° rotation of Weld Turntable and workpiece. The elevation of Weld Turntable and workpiece are driven with hydraulic station, transmitted with leadscrew or chains, depending on vertical stroke in the Head and Tail Servo Drive Welding Positioner.
1) High precision control demand on workpiece angular and linear position: ±0.02°~ 0.05° and ± 0.1mm;
2) Where working site is not applicable for manual operation, such as painting or any other pernicious environment;
3) More than 3 control axis needed for welding operation --- This need to be accomplished with robot welding;
2. Application Industries: So, Servo drive Welding Positioner is usually applied in Aviation, Military Use, Measurement Instrument, High Speed Express, where top level positioning management are entailed;
3. Related Welding Equipment: Same as other types of Rotary Welding Positioner, the mated welding equipment with servo drive Weld Turntable are:
1) Welding Manipulator (Column and Boom welding equipment);
2) Welding Rotator (Turning Roller Bed);
3) Various types of Special Welding Machine;
4) Welding Fixture (Requisite working assistant element), etc.
1) When Not in Work: For Elevating type Welding Positioner, including L type and double columns, everyday at the completion of welding operation, be sure to descend the L arm and Weld Turntable to its original bottom position close to workshop floor. This is for safety purpose of operator and equipment Welding Positioner itself;
2) Daily Maintenance: For all kinds of Rotary Welding Positioner, everyday before its official working, operator need to check on and make sure the prime condition of welding fixture and Weld Turntable: This is also for the reason of maintaining safe condition of personnel and Welding Positioner, as well as making sure workpiece will not be damaged, in case there is defect issues with welding fixture of Rotary Welding Positioner.
