Due to the large mass of large-sized stainless steel casting workpieces, a robot is required to assist in loading and positioning. However, after the robot transports the material to the fixture, it is difficult for the operator to move the stainless steel casting workpiece back and forth by fine-tuning the movement trajectory of the robot, so that the positioning hole at the rear end of the stainless steel casting workpiece is matched with the positioning protrusion on the fixture for positioning. However, the small-sized fine-tuning movement of the robot is not easy to control, and the use cost of this high-precision control robot is high. Therefore, there are problems of high use cost and control difficulty leading to low processing efficiency. Summary of the invention
