S203, the system software automatically controls each shaft of the lathe bed to move to the position to be clamped of the pipe, and in order to save time and improve efficiency, the step S204 is executed at the same time.

And S204, controlling an automatic feeding mechanism to start automatic feeding.

S205, the system software confirms that the automatic feeding mechanism feeds materials in place according to the signal setting, for example, the feeding position of the automatic feeding mechanism can be detected, and whether the automatic feeding mechanism feeds materials in place is confirmed according to the position of the automatic feeding mechanism.

Specifically, according to the specification information of the introduced pipe to be clamped and the feeding length information of the pipe, the stop position baffle preset by the pipe is positioned within the range of the processing breadth of the lathe bed and does not interfere with the feeding interval.

When a pipe is fed to a material supporting mechanism to support a set position, the mechanical arm is in a state to be clamped, the servo motor pushes the pipe to advance along the direction parallel to an X axis at the moment, the pipe enters an operation state according to operation logic set by the system, an induction signal is generated when the pipe touches a baffle induction switch and is fed back to the system, the servo motor is controlled not to push the pipe to advance any more, the position is recorded as an A point, the servo motor is controlled to retreat to a set safety position, meanwhile, the X-axis distance X1 between a rear chuck and the baffle induction switch and the detected X-axis distance X2 between the A point and the baffle induction switch are sent to system software, so that the system software controls the rear chuck to enter the operation state according to the operation logic set by the control system and operates to a preset X1-X2 position, and ensures that the rear chuck can clamp the pipe, and does not interfere with the rest of the structure. After back chuck jack catch centre gripping tubular product target in place, the manipulator begins to retreat the back of targetting in place, and back chuck gets into running state according to the operation logic that control system set for, and back chuck is according to the X axial relative distance X3 (this parameter can do self-defined setting and adjustment according to actual demand) of tubular product inductive position and preceding chuck position, and it can guarantee again that tubular product extension is as few as possible to advance to can guarantee that the cutting head can cut the tubular product within the scope, improves the utilization ratio of tubular product effectively.

S206, when the automatic feeding mechanism feeds the pipe in place, the ejection mechanism is controlled to perform an ejection action, and the rear chuck is controlled to run in place according to the length of the pipe detected by the automatic feeding mechanism, so that the rear chuck performs pipe clamping operation.
