9. A machining process method for correcting a welding device based on the heat treatment simulation tool as set forth in any one of claims 1 to 8, characterized by comprising the steps of:
the method comprises the following steps that firstly, a speed reducing motor is started, workpieces to be welded are conveyed to the position of a material stirring assembly (11) through an automatic conveying platform (10) of an automatic workpiece conveying mechanism (1) for the workpieces to be welded, when the speed reducing motor drives an incomplete driving gear (131) to rotate, a boss on the outer side surface of the circumference of the incomplete driving gear (131) is buckled with a limiting rod (123), when a clamping block (121) for stirring the limiting element (12) is separated from a clamping groove arranged in the circumferential direction of a ratchet wheel (112), two adjacent material stirring rods (114) on a material stirring turntable (113) drive the workpieces to be welded to be conveyed to a welding operation table (2) and directly conveyed to a welding station;
step two, starting a driving motor, conveying a workpiece to be welded to a welding station according to the step, namely conveying the workpiece to be welded to a rotary table (30) of an automatic correction welding positioning structure (3), pressing a power driving rod (33), mutually buckling two automatic correction welding fixtures (31), correcting, clamping and positioning the position of the workpiece to be welded, and driving the rotary table (30) to rotate through rotation to correct and adjust the position of the workpiece to be welded;
thirdly, three power motors of the spray welding manipulator (4) are started, a high-pressure air cylinder controlled by a main controller drives a moving part (43) to move up and down along a vertical guide rod, simultaneously, a mechanical arm (45) drives a spray welding gun (47) to weld clockwise or anticlockwise along the circumference of a workpiece to be welded, which is not in contact with two automatic correction welding fixtures (31), and the position of the workpiece to be welded is corrected and limited and the position of the workpiece to be welded, which needs to be welded, is changed by combining a correction rotating piece (52) of a correction limiting structure (5) through the rotating angle of a turntable (30);
and step four, the motion trail of the mechanical arm (45) in the step three is realized by controlling the motion of the three power motors, the first connecting piece (44), the second connecting piece (46) and the moving part (43) through a main controller of a control loop.
10. The welding process method for the calibration welding device of the heat treatment simulation tool according to the claim 9, wherein the moving part (43) in the third step is to move the moving part (43) up and down by the rotation of a threaded rod on an output shaft of a power motor (42).
