Advantages and load conditions of seat type welding positioner and two-seat welding positioner

The seat of the seat type welding positioner has a degree of freedom of overall turning, and to some extent, it can effectively flip its work to the ideal welding position for welding. There is also a table for the seat type welding positioner. The degree of freedom of rotation, this type of positioner has been serially produced, mainly used for the welding of some tubes and discs. The table side of the seat type welding positioner is supported on the inclined shafts on both sides of the slewing mechanism. When the operation is performed, the table will rotate at the welding speed, and when used, the slanting side passes through the sector gear or the hydraulic cylinder. It is inclined at a constant speed in the range of 140°. The machine has good stability and generally does not need to be fixed on the ground foundation, and the moving is convenient.

The applicable range of the seat type welding positioner is the reverse displacement of the 50t workpiece. It is the most widely used structural form to a certain extent, and is often used in conjunction with the telescopic arm welding machine when operating. A seat-type positioner is a device that allows the weld to be in a horizontal or boat-shaped position by turning or tilting the table. The table rotation adopts variable frequency stepless speed regulation, and the table is driven to tilt by a sector gear or a hydraulic cylinder. It can be controlled in conjunction with the operator or welder. The control system is available in three configurations: push button digital control, switch digital control and switch relay control. This product is used for the welding of various rotary parts such as shafts, discs and cylinders. It is currently the most widely used structural form.

The seat type welding positioner can be effectively divided into a seat type positioner and a small seat type positioner according to the difference of the load. The stability of the whole equipment is good, and it is generally not fixed on the foundation. It is convenient to move, and it is the largest structural form with the largest output, the most complete specifications and the most widely used. Often used in conjunction with telescopic arm welding machines or arc welding robots.

The two-seat welding positioner is a displacement machine that combines the turning and turning functions to a certain extent. The flipping and turning are driven by two shafts respectively. In addition to being able to rotate around the axis of the workpiece, the table that holds the workpiece can be tilted or flipped around the other axis, which can adjust the welds at various positions on the weldment to Horizontal or "ship" welded position for welding, suitable for frame, box, disc and other non-long workpiece welding.

The two-seat welding positioner not only has good overall stability, but also has a proper design in the process of operation. After the workpiece is placed on the workbench during operation, the center of gravity of the tilting movement during operation will be Will effectively pass or approach the tilt axis, which will greatly reduce the tilt drive torque.

Therefore, heavy-duty positioners often use this structure. Its application range is overturning displacement of heavy-duty large-sized workpieces above 50t, and it is often used in conjunction with large-scale door welding machines or telescopic arm welding
