[0020] The working principle of this utility model is as follows: When the blank casting is completed, a blank pre-drilling hole 1101 is reserved in the middle of the blank. First, the blank casting is installed on the connecting rod jaw 604 and clamped. The CNC system inside the machine tool is programmed and controlled. Then, the spindle 5 moves the workpiece 11 blank to the oil nozzle drilling unit 7 and rotates to a specified angle. The first reduction motor 703 drives the oil nozzle drill bit to rotate. At this time, the spindle 5 moves to maintain feed. After drilling is completed, the spindle 5 drives the workpiece 11 to rotate and moves the workpiece 11 blank to the drilling power head unit 8 to mill the bottom of the workpiece 11 blank. After the bottom milling is completed, the reserved hole 1101 in the middle of the workpiece 11 is aligned with the boring and milling cutter head 801 and rough boring is performed on the metal outer skin. Then, the spindle 5 stops rotating. After rotating to a specified angle, the locking cylinder 504 is controlled to lock the spindle 5, and the positioning hole drill bit 802 rotates. The workpiece 11 moves to the designated position and continues to move downwards to complete the machining of the surrounding positioning holes 1103. Then, the workpiece 11 moves to the oscillating boring unit 9, and the locking cylinder 504 retracts. The first servo motor 503 rotates, driving the workpiece 11 to rotate. Then, the workpiece 11 moves to the designated position, and the third reduction motor 903 drives the circular gear 904 to rotate. The circular gear 904 drives the sector gear 905 to rotate, realizing the oscillation of the oscillating tool holder 902 and the tool holder 906, thereby realizing the rough boring, oil groove cutting and fine boring operations on the center reserved hole 1101. Finally, the workpiece 11 moves to the designated position on the left side of the oil nozzle tapping unit 10 and rotates to the designated angle. The second reduction motor 1003 rotates, driving the oil nozzle tap to rotate. Due to the cooperation of the toothed shaft 1007 and the nut cover 1008, the oil nozzle tap will be stably fed to the left, thereby realizing the tapping operation on the oil nozzle hole 1102.
