Product Introduction For L type robot welding positioner:
The L type robot welding positioner adopts an L-shaped structure with good openness, suitable workpiece clamping height, is convenient for welding operation, and is suitable for structural parts with many weld positions. When welding, the welding seam is in the best position, avoiding the upward welding and vertical welding, ensuring the welding quality, and changing the L type robot welding positioner according to the welding seam requirements of the workpiece. The L type robot welding positioner guarantees safety during the welding, and turning of the workpiece reduces the labor intensity of the operator and improves productivity.
The high-precision AC servo drive system is used for rotation, turning, and lifting, which can accurately position the workpiece and ensure the position accuracy of the workpiece in space. It can be operated independently and can be used in conjunction with the welding robot.

Machine Advantages For L type robot welding positioner:
The machine structure adopts a precision processing workbench, which is not easy to be damaged by the flying sender and has a long service life; the frame is formed by tailor welding of plates and profiles, and after welding, it is annealed to have sufficient mechanical strength and ensure that it will not be used for a long time. Deformed. The slewing mechanism and turning mechanism are installed on the frame through bearings and precision slewing bearing seats.
The heavy-duty precision slewing bearing is used for the slewing bearing, which has a high bearing capacity, small side clearance, and a large design margin, thereby reducing the amount of axis runout after the workpiece is turned over and ensuring the position accuracy.
Servo motor shaft and precision reducer adopt Japan Nabtesco precision RV reducer, stable performance, and no noise all year round; shaft hole adopts a direct connection structure, high transmission accuracy.

Precautions for the use of L type robot welding positioner:
1) Pay attention to the welding position (especially welding height) caused by the tilting movement of the L type robot welding positioner.
2) Pay attention to adjusting the rotation speed or tilting speed of the worktable to meet the welding speed requirements. During the return stroke (displacement), the rotation speed can be appropriately increased to improve the displacement efficiency.
3) Connect the conductive device properly, and replace the brush in time after the brush is worn; the welding cable cannot be arbitrarily placed on the frame to prevent the welding current from passing through the transmission mechanism such as bearings, affecting the transmission performance (which may cause arcing) and damaging the machine.
4) Pay attention to the control of the tilt angle, and if necessary, add mechanical limit measures on the body.
5) Pay attention to the verification of the displacement load capacity to prevent various adverse consequences of overload operation. When replacing workpieces, especially those with severe eccentricity or high center of gravity, the maximum turning torque, and maximum tilting torque should be checked.
