What is the purpose of the L type robot welding positioner?

L type robot welding positioner is universal and efficient welding equipment that mainly realizes circular seam welding. To ensure a good welding effect, we will use the L type robot welding positioner to help us, during the welding operation, the welding positioner can help us get a better welding angle. The L type robot welding positioner can be equipped with welding machine power such as an argon arc welding machine (wire filled or not), molten gas shielded welding machine (C02/MAG/MIG welding machine), plasma welding machine, and other welding machine power sources and can be combined with other machines to form an automatic Welding system. The L type robot welding positioner is mainly composed of a rotating head, positioner, and controller. The speed of the rotating machine head is adjustable, with an independent speed regulation circuit, and the DIP switch directly presets the weld length. The tilt angle can be adjusted as required.

What are the benefits of using L type robot welding positioner?

The L type robot welding positioner is the special auxiliary equipment for welding, which is suitable for the welding position of the rotary work to obtain the ideal processing position and welding speed. It can be used with welding manipulators and welding machines to form an automatic welding center, and it can also be used for manual operations. When the workpiece is displaced.
1.With RV reducer, the repeatability of the welding positioner can reach +0.1 mm.
2.A simple drive system can reduce the risk of failure.
3.The main function of the welding positioner is to realize the flip and position of the workpiece during the welding process, to obtain a better welding position, which can meet a variety of welding quality and appearance requirements.
4.The base of the positioner is welded with thickened profiles and steel plates and is annealed to ensure reliable quality and accuracy.
5.The turning is driven by a servo motor, and the reducer adopts a high-precision reducer with reliable accuracy and adjustable speed.

How to troubleshoot when using an L type robot welding positioner?

1.There are many reasons why the motor does not work when the workbench is tilted. We analyze the following one by one:
(1) The contact of the contactor is not in good contact, phase loss, or coil failure. In this way, the contactor contacts can be processed and the contactor can be replaced if necessary.
(2) The thermal relay fails or malfunctions. Just replace the thermal relay or reset it.
(3) If the button fails, repair, or replace the button.
(4) The motor brake is not opened or the motor load terminal is loose and the contact is not good: check the motor brake device and tighten the load terminal.
2.After pressing the button, if there is no lifting action or unidirectional action, it may be because the limit mechanism is stuck or the contact is faulty, so just replace the limit. It may also be that the button contacts are not in good contact or the button return spring is damaged. Just repair it. If it can’t be repaired, just replace the button. There may also be a misoperation of the thermal relay with a small setting current or a thermal relay failure. You can adjust the setting current or replace the thermal relay. If the motor does not operate, humming sound, the contactor lacks phase, and the load terminal is not in good contact. If this happens, check the contactor and replace the contactor if necessary, and tighten the load terminal.
3.The rotary table of the positioner does not move.
(1) The speed regulating potentiometer of the remote control switch fails, and the speed regulating potentiometer can be replaced.
(2) Whether the workbench forward and reverse relays CR1 and CR2 are active, you can check whether the wiring is loose and whether the relay is faulty, tighten the wire, or replace the relay.
(3) The inverter panel is not in good contact and the screws are loose. You can check the inverter and tighten the screws to make the contact well.
(4) Check whether the worktable rotary brake contactor KM5 is active and the brake is opened. You can check whether the brake wiring and contactor are faulty, tighten the screws, solve the contactor failure, and replace the contactor if necessary.
(5) Check whether the near control or remote control switch is in place, whether the button is faulty, you can replace the switch or button.
(6) The up limit switch connected to the inverter is faulty, the limit switch can be replaced.
(7) Check whether the wiring of the circuit breaker on the front side of the inverter's main circuit is firm and whether there is a phase loss. If the wiring is loose, tighten the wiring terminals to make good contact. If the circuit breaker fails, replace the circuit breaker.
(8) If the brake is not opened, check the brake device, first check whether there is any fault or damage, and replace it in time.
There are many reasons for the failure of the welding positioner. If you encounter any problems during operation, you must investigate and find the problems one by one, and repair them in time, and do a good job in the maintenance of the machine.

Where can I buy L type robot welding positioner chucks?

How does the L type robot welding positioner work?

The composition and application of the L type robot welding positioner are mainly to make the workpiece in the best welding position through the movement of the worktable, such as lifting, turning, and turning and has a variety of structural forms such as seat type, L type, lifting type and double column. It can be matched with a welding manipulator to form an automatic welding machine, and it can also be matched with a welding robot to realize automatic welding.

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.
