10. A method for automatically calibrating and punching holes in metal door panels of explosion-proof cabinets, which is applied to the automatic calibrating and punching holes in metal door panels of explosion-proof cabinets as claimed in claim 9, characterized in that: The steps of automatic calibration punching method are as follows: Step 1: First, move the metal cabinet door to the top of the processing table (1), turn on the third stepper motor (9), and the third stepper motor (9) drives the bidirectional threaded rod (10) to rotate. Under the action of the threads on the surface of the bidirectional threaded rod (10), the two clamping arms (11) move towards each other and clamp the metal cabinet door. Then, turn on the electric telescopic rod (42), and the electric telescopic rod (42) pushes the connecting plate (45), so that the fixed column (44) drives the rotating disk (43) to rotate, thereby causing the rotating base (41) to rotate in the inner cavity of the fixed frame (2). During the rotation process, the rotating base (41) drives the hole drill (3) to rotate, so that the drill bit of the hole drill (3) remains in a vertical state downward. Then, the first stepper motor (84) and the second stepper motor (87) are turned on, and the first stepper motor (84) drives the first threaded rod (83) to rotate, so that the first threaded rod (83) pushes the sliding seat (85) through its surface threads, so that the sliding seat (85) slides on the bottom of the top seat (81), and at the same time, the second stepper motor (87) drives the second threaded rod (86) to rotate, and the threads on the surface of the second threaded rod (86) push the displacement seat (88), so that the displacement seat (88) slides back and forth in the inner cavity of the sliding seat (85), and in the process of the displacement seat (88) moving, the fixed frame (2) is driven to move, and at the same time, the drilling position is calibrated by the capture camera (64); Step 2: After the capture camera (64) accurately calibrates the drilling position, the first stepper motor (55) is turned on and drives the driving bevel gear (56) to rotate. Due to the meshing of the driving bevel gear (56) and the force bevel gear (57), the rotating tube (51) on the right side rotates. Under the meshing transmission action of the synchronous gear (52) and the synchronous rack (53), the two rotating tubes (51) rotate at the same time. During the rotation process, the rotating tube (51) drives the sliding column (61) to rotate. During the rotation process, the sliding column (61) drives the connecting arm (62) to rotate. During the rotation process, the two connecting arms (62) respectively drive the belt positioning tube (63) and the capture camera (64) to rotate. After the rotating tube (51), the sliding column (61) and the connecting arm (62) rotate 180 degrees at the same time, the capture camera (64) and the belt positioning tube (63) alternate positions, so that the belt positioning tube (63) accurately reaches the drill bit position of the hole drill (3); Step 3: Subsequently, the second stepper motor (74) is turned on and drives the transmission column (77) to rotate. During the rotation process, the transmission column (77) drives the driving gear (78) to rotate. Due to the meshing transmission effect of the driving gear (78) and the rack (75), the sliding sleeve (72) falls back downward, and the sliding sleeve (72) drives the lifting tube (73) to slide downward, thereby causing the top seat (81) and the displacement seat (88) to drive the fixed frame (2) to slide downward. During the sliding process, the fixed frame (2) drives the hole drill (3) to move downward through the rotating base (41), so that the positioning tube (63) reaches the accurately marked drilling position. Subsequently, the hole drill (3) and the rotating base (41) continue to press downward and squeeze the sliding column (61) located on the left side, so that the spring (65) is compressed. Subsequently, the drill bit of the hole drill (3) penetrates the inner cavity of the positioning tube (63) and enters the drilling position to drill holes.
