The manual intervention overturning method of the travelling crane has potential safety hazards, the position of the workpiece after overturning is difficult to ensure, the workpiece is required to be positioned again before machining, and the working procedure is long. The two ends of the workpiece are required to be fixed when the existing small-size positioner is applied. The large-size positioner is generally a full-circle type wrapping and fixing workpiece, and the fixing point is arranged at the middle section of the workpiece and has interference on the processing of the workpiece; and because the workpieces are wrapped in a full-circle rotation mode, the lifting loading is inconvenient, and the workpiece replacement step for completing the machining of each workpiece is tedious and consumes more time.

However, in practical application, the workpiece input data cannot always be guaranteed to be accurate, and when errors occur, potential safety hazards are generated in the task execution process of the positioner. For example, when the input workpiece data is larger than the actual size of the workpiece, virtual clamping of the positioner can be caused, vibration can be generated when the workpiece is overturned, and the mechanical structure of the positioner is damaged; when the input workpiece data is smaller than the actual size of the workpiece, the servo motor driving the clamping member may be blocked, thereby stopping the task.
