People who have been exposed to welding work must know that the welding positioner is a mechanical device used to drag the workpiece to be welded so that the weld can reach the appropriate position for welding. It is widely used in the welding industry. So what kind of performance does the welding positioner have to ensure the smooth progress of the welding work? First, the structural rigidity of the equipment itself must be strong, so that it can withstand the impact of welding, and the equipment can have a wide range of speed modulation in order to be suitable for the welding of more workpieces. Secondly, , the transmission chain of the positioner must have a good self-locking device, so that when the power is disconnected, the workpiece will not cause an accident due to inertia. And now the requirements for welding are very high, and the equipment must achieve high precision, so that it can meet the requirements. In addition, the Beijing car rental company told us that the welding positioner must have a certain return speed, so that there will be no impact and vibration. The sealing of the equipment must be good, which can effectively prevent welding materials from entering the equipment and affecting the operation of the equipment.
