[0050] Step 6, after one hole is processed, the drilling cutter 8 exits.
[0051] Step 7, the whole tooling on the drilling machine moves to the right to the set distance and stops.
[0052] Step 8, the high-speed rotating drilling cutter 8 moves downward, passes through the other through hole 7 of the cross beam 13, drills and chamfers at the set depth on the other position of the nameplate plane of the water pump top cover 4, after another hole is processed, the drilling cutter 8 retreats to the original position, and the whole tooling on the drilling machine moves to the left to the original position.
[0053] Step 9, the main shaft of the two lifting oil cylinders 21 retreats, drives the two supporting blocks 22, the supporting block 31, the connecting plate 32, the positioning edge plate 51, the two positioning screw rods 52 and the water pump top cover 4 to move downward to the initial position, and the water pump top cover 4 with drilled holes is taken out.
