High-precision stability single-holding double-shaft positioner

The utility model relates to the field of welding equipment, and discloses a high-precision stability single-holding double-shaft positioner which comprises a machine base, a robot body is fixedly installed on the top side of the machine base, the robot body is located in the middle of the machine base, and a welding head is arranged on the robot body. Two sets of single-shaft speed variators and two sets of driven shafts are installed on the top side of the machine base. According to the welding robot, when a product on the first product frame is welded, the robot body can turn to the position above the first product frame, when the product on the first product frame is welded, a worker moves to the position of the second product frame and places the product on the second product frame, and therefore the effect that the product is welded on the second product frame while welding is completed can be achieved. The other side can be directly welded without needing to wait, meanwhile, the waiting time of product
