Welding positioner general mechanism by rotary table and flip agencies, by elevating table, flipping and rotating the fixed workpiece on the table to achieve the required welding, assembly angle, rotary table for frequency conversion stepless obtained satisfactory welding speed. Jinan welding up the main production welding positioner equipment, engaged in production for many years, with many years of production experience, can provide custom-designed non-standard variable-bit machine, reliable positioner factory quality, affordable and widespread customer favorite, for many years get the praise of customers, if the relevant business, customers are welcome to negotiate cooperation, the factory will be happy to serve you. Positioner is special welding auxiliary equipment, suitable for welding positioner rotary work to get ideal processing position and welding speed. With operating machines, welding machine supporting the use of automatic welding center composition can also be used for the displacement of the workpiece during manual operation. Rotary table with inverter variable speed, speed and high accuracy. Remote control box enables remote operation of the table can also be connected with the operation of the machine, welding machine control system to realize linkage operation. Mainly used for the shaft, disk, round, circular piece of flipping back transition bit to get the ideal processing position and welding speed. Workpiece displacement ring can be used for manual welding, assembly, repair and other occasions seam welding, also used with operating machines, welding machines and other equipment for use, consisting of automatic welding center; can be used for manual welding workpieces, assembly, repair and other occasions displacement girth weld welding. The device can be fixed on the table chuck or a specific workpiece clamping fixture for use with manual welding, can also be achieved with automatic welding machine supporting the use of welding operation, can be used for cutting, grinding, assembly, testing and other processes
