10. A method for processing a ball valve hard seal seat, using a ball valve hard seal seat processing lathe according to claim 9, characterized in that: The following steps are involved: Step 1, conveying the valve seat: start the first electric cylinder (10) to drive the distance adjustment box (5) to rise between the plurality of lifting chutes (9); start the first drive motor (8) to drive the bidirectional screw rod 1 (7) to rotate according to the volume of the valve seat to be processed, adjust the positions of the two conveying boxes in the distance adjustment box (5), and then place the valve seat between the two conveyor belt structures (6) in the processing machine box (40), so that the conveyor belt structure (6) conveys the valve seat and moves the valve seat to the bottom of the two nearest rotating frames (11); Step 2, clamping the valve seat: starting the second electric cylinder (26) to drive the sliding groove body (25), the mounting member (27) and the mounting cylinder (29) to descend, so that the two positioning sensors (30) correspond to each other through the hollow valve seat, and then determining that the center point of the mounting cylinder (29) corresponds to the valve seat, and then starting the double-headed electric cylinder (28) to drive the two mounting members (27) to move relative to each other, so that the mounting cylinder (29) contacts the end surface of the valve seat, and then clamping the valve seat; Step 3, adjusting the position of the valve seat: starting the second electric cylinder (26) so that the height of the valve seat corresponds to the position of the two rotating frames (11), and then starting the first electric cylinder (10) to drive the distance adjustment box (5) to descend, so that the conveyor belt structure (6) descends together, and reserves space for the movement of the rotating frame (11); Step 4, secondary clamping: starting the fourth drive motor (32) to drive the second bidirectional screw (31) to rotate, adjusting the distance between the two mounting trusses (4), and making the arc-shaped clamping member (19) contact the valve seat when the rotating frame (11) moves toward the valve seat, and under the action of the spring damper (18), making the arc-shaped clamping member (19) clamp the valve seat; Step 5, adjusting the position of the valve seat: after the valve seat is clamped between the two rotating frames (11), the valve seat is processed using the lathe processing end (2), and then the second drive motor (14) is started to drive the rotating shaft (12) and the driving wheel (13) to rotate, so that the driving wheel (13) drives the valve seat to rotate. When it is necessary to drive the valve seat to adjust another angle, the third drive motor (22) is started to drive the adjustment shaft (16) to rotate through the meshing operation of the transmission worm wheel (23) and the transmission worm (24), so that the two rotating frames (11) are meshed together through the meshing slot (20) and the meshing plug (21), and then the two rotating frames (11) rotate along the adjustment shaft (16) to adjust the position of the valve seat, so that the valve seat can be fully cut; Step 6: Valve seat processing: Through the above method, the valve seat is fully cut between the multiple lathe processing ends (2).
