[0044] The working principle of the embodiment of the present application is:

[0045] As Figures 1-10As shown, by respectively disposing a turning mechanism 4 and a drilling mechanism 5 on two sets of sliding guide rails 10, and combining them with a follower mechanism 6 to achieve synchronous movement of the turning mechanism 4 and the drilling mechanism 5 along the sliding guide rails 10, and combining them with a power switching assembly 7 to switch the longitudinal adjustment power on the turning mechanism 4 to the drilling mechanism 5, the control of the turning tool head 47 approaching the workpiece is switched to controlling the drill bit approaching the workpiece, thereby reducing the number of power components installed and the overall size of the machine tool. After the turning mechanism 4 completes the turning process of the workpiece, a swing frame 69 is provided using a follower frame 60 slidably mounted on the bottom of the frame 1. The swing frame 69 is controlled to rotate by a swing motor 612, so that the clamping column 611 on the arc frame 610 falls into the arc-shaped slot 2 63 on the suspension column 62, thereby clamping the suspension column 62. The turning mechanism 4 then synchronously controls the movement of the drilling mechanism 5, thereby achieving drilling of the workpiece along the sliding guide rails 10. By installing a spring post 64 and a detection ball 66 at the bottom of the suspension post 62, the follower mechanism 6 moves with the turning mechanism 4. When the detection ball 66 on the suspension post 62 slides across the mating groove 67 and falls into the mating hole 68, the swing motor 612 is activated, controlling the rotation of the swing frame 69 and the arc frame 610, causing the clamping posts 611 on the arc frame 610 to fall into the second clamping grooves 63 on both sides of the suspension post 62, thereby causing the drilling mechanism 5 to move with the turning mechanism 4. Triangular chucks 1 2 and 2 30 are respectively installed at both ends of the frame 1 to achieve separate clamping of the two ends of the workpiece, thereby facilitating independent drilling operations on both ends of the workpiece and eliminating the need to disassemble the workpiece for reversing and fixing. The turning head 47 of the turning mechanism 4 is mounted on the upper side of the longitudinal frame 1 42. The turning head 47 is controlled by rotating the adjusting screw 1 43 to move closer to or further away from the workpiece. To facilitate switching power to the drilling mechanism 5, the power connection between the adjusting screw 1 43 and the longitudinal frame 1 42 is disconnected. An electric telescopic chuck 45 is provided within the longitudinal frame 1 42, and the electric telescopic chuck 45 cooperates with the threaded mating sleeve 44 to achieve a power connection between the adjusting screw 1 43 and the longitudinal frame 1 42. The adjusting screw 2 53 controls the movement of the longitudinal frame 2 52, thereby controlling the drilling machine 59 to move closer to or further 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 adjustment 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 connector 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 connector 76 to dock with each other, thereby transmitting the power on the adjustment 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.
