The internal annular array of the swivel seat 8 is provided with a plurality of electromagnets 14. The side wall of the top block 12 is fixedly connected with a permanent magnet 15. The electromagnet 14 cooperates with the permanent magnet 15. The lower end of the movable plate 7 is fixedly connected with a laser rangefinder 19. The operator fixes a variety of different turning tools to the lower ends of the multiple movable blocks 10. The bottom plate 2, the plate 3, and the movable plate 7 are respectively driven to slide by a plurality of electric slides. The rotating seat 5 and the swivel seat 8 are driven to rotate by two motors. The operator fixes the workpiece on the side wall of the rotating seat 5, drives the workpiece to rotate through the rotating seat 5, rotates the rotating seat 8, and rotates the corresponding turning tool to the top of the workpiece. One of the electromagnets 14 generates a repulsive magnetic force, so that the permanent magnet 15 pushes the top block 12 to slide horizontally. At the same time, the top block 12 pushes the movable block 10, so that the movable block 10 slides downward. After the top block 12 slides completely, the lower end of the top block 12 fits with the lower end of the movable block 10, thereby ejecting the corresponding turning tool. The movable plate 7 slides longitudinally, so that the turning tool performs turning processing on the workpiece. At the same time, the bottom plate 2 and the plate 3 slide at the appropriate time. When the turning tool needs to be switched, the electromagnetic force of the electromagnet 14 disappears, and the top block 12 slides to the inside of the swivel seat 8. At the same time, the movable block 10 drives the turning tool set at the lower end to slide to the inside of the slot 9. The swivel seat 8 rotates, and the turning tool to be used is rotated to the top of the workpiece, and then it is ejected through the above steps. The distance between the turning tool and the workpiece is measured in real time by the laser rangefinder 19, and the mechanical vibration generated by the entire device during the processing is monitored in real time by the vibration sensor 20.

The controller 21 is electrically connected to the laser rangefinder 19, the vibration sensor 20 and multiple electromagnets 14 respectively. The distance information between the turning tool and the workpiece is obtained in real time through the connection between the controller 21 and the laser rangefinder 19. The vibration condition of the entire device during the processing is monitored in real time through the connection between the controller 21 and the vibration sensor 20. When the turning tool needs to be replaced, the controller 21 will send a signal to the corresponding electromagnet 14 to generate a repulsive magnetic force, thereby pushing the top block 12 to realize automatic replacement and positioning of the turning tool.
[0027] In the present invention, the operator fixes the workpiece on the side wall of the rotating seat 5, drives the workpiece to rotate through the rotating seat 5, rotates the rotating seat 8, and rotates the corresponding turning tool to the top of the workpiece. The controller 21 will send a signal to the corresponding electromagnet 14 to generate a repulsive magnetic force, so that the permanent magnet 15 pushes the top block 12 to slide horizontally, and at the same time the top block 12 pushes the movable block 10, so that the movable block 10 slides downward. After the top block 12 slides completely, the lower end of the top block 12 fits with the lower end of the movable block 10, thereby ejecting the corresponding turning tool, and the movable plate 7 slides longitudinally, so that the turning tool performs turning processing on the workpiece.
[0028] When the turning tool needs to be switched, the controller 21 controls the electromagnet 14 to cut off the electromagnetic force, and the elastic force of the spring 13 is used to pull the top block 12 to slide, so that the top block 12 automatically slides and resets, and the elastic force of the spring 2 18 pushes the slider 17 to slide upward, so that the slider 17 drives the movable block 10 to automatically slide and reset, and the turning tool is stored in the slot 9. The swivel seat 8 is rotated, and the turning tool to be used is rotated to the top of the workpiece, and then it is ejected through the above steps to perform turning processing on the workpiece.
