[0039] Specifically, when it is necessary to switch the power from the turning mechanism 4 to the drilling mechanism 5, first control the adjusting screw 43 to rotate so that the longitudinal moving frame 42 is away from the workpiece, and then control the electric telescopic chuck 45 and the threaded matching sleeve 44 to separate. At this time, the electromagnet 71 on the connecting head 70 is energized so that the electromagnet 71 and the sleeve magnet 74 have the same magnetic properties, generating a mutual repulsive force, pushing the docking column 75 and the docking hole 77 on the connecting head 76 to dock with each other, thereby transmitting the power on the adjusting screw 53 to the drilling mechanism 5, thereby controlling the drilling mechanism 5 to approach or move away from the workpiece and perform drilling operations.

The triangular chuck 1 2 and the triangular chuck 2 30 are respectively set at both ends of the frame 1 to realize the separate clamping of the two ends of the workpiece, so as to facilitate the separate drilling operation of the two ends of the workpiece, eliminating the operation of disassembling the workpiece for reversing and fixing. The turning tool head 47 in the turning mechanism 4 is installed on the upper side of the longitudinal moving frame 1 42. By controlling the rotation of the adjusting screw 1 43, the turning tool head 47 is controlled to approach or move away from the workpiece. In order to facilitate the power switching to the drilling mechanism 5, the power connection between the adjusting screw 1 43 and the longitudinal moving frame 1 42 is disconnected at the same time. By arranging an electric telescopic chuck 45 in the longitudinal moving frame 1 42, the electric telescopic chuck 45 and the threaded matching sleeve 44 cooperate with each other to realize the power connection between the adjusting screw 1 43 and the longitudinal moving frame 1 42. The adjusting screw 2 53 controls the movement of the longitudinal moving frame 2 52 to realize the control of the drilling machine 59 approaching or moving away from the workpiece. When it is necessary to switch the power from the turning mechanism 4 to the drilling mechanism 5, first control the adjusting screw 43 to rotate so that the longitudinal moving frame 42 is away from the workpiece, and then control the electric telescopic chuck 45 and the threaded matching sleeve 44 to separate. At this time, the electromagnet 71 on the connecting head 70 is energized so that the electromagnet 71 and the sleeve magnet 74 have the same magnetic properties, generating a mutual repulsive force, pushing the docking column 75 and the docking hole 77 on the connecting head 76 to dock with each other, thereby transmitting the power on the adjusting screw 53 to the drilling mechanism 5, thereby controlling the drilling mechanism 5 to approach or move away from the workpiece and perform drilling operations.
