In particular, the positioner is an auxiliary equipment for special welding robots, suitable for welding position adjustment during rotary work to obtain the ideal processing position and welding speed.

[0003] For example, patent number CN208467560U discloses an industrial welding robot positioner workstation, including: a base, a column, a screw, an adjustment motor, a cantilever, a rotary motor, a rotary table, a stepper motor, and a workbench; the column is arranged on the upper surface of the base, and the column and the base are connected by welding; the screw is arranged inside the column, and the screw is connected to the column by a bearing; the adjustment motor is arranged at the top of the column, and the adjustment motor is connected to the column by a through-fixing manner; the cantilever is arranged on one side of the column, and the cantilever is connected to the column by a screw; the rotary motor is arranged in the middle position of one end of the cantilever, and the rotary motor is connected to the cantilever by a through-fixing manner; the rotary table is arranged at the top of the rotary motor, and the rotary table is connected to the rotary motor by an embedded manner; the stepper motor is arranged in a rectangular shape at the bottom of the rotary table, and the stepper motor is connected to the rotary table by a through-fixing manner; the workbench is arranged at the top of the stepper motor, and the workbench is connected to the stepper motor by an embedded manner. The utility model utilizes the four work tables to cooperate with each other through the rotation of the rotary table, so that a continuous welding process processing mode can be formed between the workpieces, thereby greatly improving the welding production efficiency of the workpieces. The rotary table is used to drive the work table to rotate, and the work tables can be rotated independently at the same time, thereby realizing the multi-directional workpiece rotation and positioning function, and significantly improving the welding position accuracy of the workpiece.
