The first screw rod 42 drives the lifting seat 44 to move downward by means of being threadedly connected to the lifting seat 44 and the sliding cooperation between the lifting seat 44 and the guide rod 43. The lifting seat 44 drives the processing assembly 7 to move downward synchronously by driving the mounting frame 5 to move downward synchronously, so as to perform corresponding processing on the workpiece 10. When it is necessary to process different positions of the workpiece 10, the third motor 47 drives the second screw rod 46 to rotate. The second screw rod 46 drives the mounting frame 5 to move along the length direction of the second screw rod 46 by means of being threadedly connected to the mounting frame 5 and the sliding cooperation between the mounting frame 5 and the lifting seat 44, so as to realize the synchronous movement of the processing assembly 7 and perform corresponding processing on different positions of the workpiece 10.

A supporting ring 813 is rotatably arranged outside the rotating disk 814. A toothed ring 84 is arranged outside the second fixed cylinder 83. A plurality of sliding rods 86 are circumferentially slidably arranged on the connecting cylinder 81. One end of each sliding rod 86 is connected to a limiting rack 85 that is movably engaged with the toothed ring 84. The other end of each sliding rod 86 is connected to an electromagnet 87 movably arranged outside the connecting cylinder 81.

A hinge rod 811 is movably connected between the first hinge seat 810 and the corresponding second hinge seat 812. A rotating seat 816 is rotatably arranged on the rotating disk 814. The rotating seat 816 is connected to a fourth motor 815 arranged at the bottom of the rotating disk 814. One end of the rotating seat 816 is connected to a connecting rod 817. The outer end of the connecting rod 817 is connected to a second sliding column 818. A connecting ring frame 82 is arranged at the top of the connecting cylinder 81. A plurality of guiding grooves 821 that are slidably matched with the second sliding column 818 are circumferentially distributed on the connecting ring frame 82. A limiting arc plate 822 that is slidably matched with the rotating seat 816 is arranged on the connecting ring frame 82 between two adjacent guiding grooves 821.

[0044] In this embodiment, the mounting base 61, the second sliding groove 65, the sliding rod 86, the guiding groove 821, and the limiting arc plate 822 are all provided in four. The end of the special-shaped ring groove 661 away from the vertical frame 3 protrudes downward. The rotating seat 816 is a sector-shaped rotating plate, and the outer wall of the rotating seat 816 is movably matched with the concave arc groove on the limiting arc plate 822. In the initial state, the limiting rack 85 is engaged with the toothed ring 84, the spring 89 is in its original length, the first hinge seat 810 is located on the side of the hinge rod 811 close to the second fixed cylinder 83, and the included angle between the hinge rod 811 and the vertical direction is set to the maximum value. The electromagnet 87 and the permanent magnet 88 are close to each other, and the rotating seat 816 is slidably matched with the limiting arc plate 822. At this time, the milling cutter 71 corresponds to the protruding end of the special-shaped ring groove 661 downward. The milling cutter 71 is located directly above the workpiece 10 and on the side of the mounting frame 5 close to the workpiece 10. The drill rod 72 and the grinding wheel 73 are not located directly above the workpiece 10 and are on the side of the mounting frame 5 away from the workpiece 10. The second sliding column 818 is away from the guiding groove 821, which can ensure the reliability of the rotation of the connecting ring frame 82. When the milling cutter 71 needs to be used to operate on the workpiece 10, at this time, it is not necessary to switch the position of the milling cutter 71. Only the height and horizontal position of the mounting frame 5 need to be adjusted through the adjusting assembly 4 so that the milling cutter 71 contacts the surface of the workpiece 10. The rotating assembly 2 processes the workpiece 10 correspondingly by driving the rotation of the workpiece 10 and the cooperation between the milling cutter 71 and the surface of the workpiece 10;

[0045] When it is necessary to drill the workpiece 10, the permanent magnet 88 is energized. The permanent magnet 88 moves away from the connecting cylinder 81 by interacting with the electromagnet 87. The permanent magnet 88 drives the limit rack 85 to move synchronously by connecting with the sliding rod 86, releasing the meshing between the limit rack 85 and the toothed ring 84. The sliding rod 86 is stressed and contracts. At the same time, the sliding rod 86 pushes the support ring 813 to move upward through the movable connection between the hinge seat one 810, the hinge rod 811 and the hinge seat two 812. The support ring 813 drives the rotating disk 814 to move upward synchronously by rotatingly mating with the rotating disk 814 and the sliding fit between the guiding column 8141 and the fixed cylinder two 83, so that the sliding column two 818 slides with the guiding groove 821. Then, the motor four 815 is energized. The motor four 815 drives the rotating seat 816 to rotate clockwise for one full circle and then stops working. The rotating seat 816 drives the connecting ring frame 82 to rotate clockwise by a quarter of a circle by slidingly mating with the limit arc plate 822 and the sliding fit between the sliding column two 818 and the guiding groove 821. The connecting ring frame 82 drives the rotating cylinder 64 to rotate clockwise by a quarter of a circle by connecting with the connecting cylinder 81 and the connection between the connecting cylinder 81 and the rotating cylinder 64. The rotating cylinder 64 drives the lifting plate 62 and the mounting seat 61 to rotate synchronously by connecting with the guiding groove plate 63 and the sliding fit between the guiding groove plate 63 and the lifting plate 62. The downward protruding part of the special-shaped ring groove 661 includes a left inclined area and a right inclined area. At the same time, the corresponding sliding column one 621 corresponding to the milling cutter 71 drives the corresponding lifting plate 62 and the mounting seat 61 to move upward by slidingly mating with the left inclined area of the special-shaped ring groove 661 and the sliding fit with the sliding groove two 65. The corresponding sliding column one 621 corresponding to the drill rod 72 drives the corresponding lifting plate 62 and the mounting seat 61 to move downward by slidingly mating with the right inclined area of the special-shaped ring groove 661 and the sliding fit with the sliding groove two 65. The drill rod 72 can be rotated to directly above the workpiece 10 and below the mounting frame 5. Then, the motor four 815 and the permanent magnet 88 are powered off. The spring 89 extends and pushes the sliding rod 86 to move into the connecting cylinder 81. The sliding rod 86 realizes the meshing between the limit rack 85 and the toothed ring 84 by driving the limit rack 85 to move synchronously, thereby fixing the position of the mounting seat 61. Through the rotating assembly 2, the position of the workpiece 10 can be fixed. The driving motor drives the drill rod 72 to rotate. The adjusting assembly 4 drives the drill rod 72 to move downward by cooperating with the mounting frame 5, and the surface of the workpiece 10 can be drilled. When it is necessary to drill different positions on the surface of the workpiece 10, the rotating assembly 2 rotates the workpiece 10 by driving the workpiece 10 to rotate by an angle, and the adjusting assembly 4 moves the position of the drill rod 72 by adjusting the horizontal position of the mounting frame 5, so as to meet the drilling requirements for different positions on the surface of the workpiece 10;

[0046] After the drilling is completed, the adjusting assembly 4 drives the drill rod 72 to move upward by driving the mounting bracket 5 to move upward. The driving motor stops working, causing the drill rod 72 to reset. Then, the rotating assembly 2 releases the clamping of the workpiece 10, facilitating the removal and replacement of the workpiece 10 and facilitating the corresponding processing of the subsequent workpiece 10;

[0047] When the workpiece 10 needs to be polished, the permanent magnet 88 is energized. The permanent magnet 88 moves away from the connecting cylinder 81 by interacting with the electromagnet 87. The permanent magnet 88 drives the limit rack 85 to move synchronously by being connected to the sliding rod 86, releasing the meshing between the limit rack 85 and the toothed ring 84. The sliding rod 86 is stressed and contracts. At the same time, the sliding rod 86 pushes the support ring 813 to move upward through the movable connection between the hinge seat one 810, the hinge rod 811 and the hinge seat two 812. The support ring 813 drives the rotating disk 814 to move synchronously upward by rotatingly cooperating with the rotating disk 814 and the sliding cooperation between the guiding column 8141 and the fixed cylinder two 83, so that the sliding column two 818 slides with the guiding groove 821. Then, the motor four 815 is energized. After the motor four 815 drives the rotating seat 816 to rotate counterclockwise for one full circle and stops working, the rotating seat 816 drives the connecting ring frame 82 to rotate counterclockwise by a quarter of a circle through the sliding cooperation with the limit arc plate 822 and the sliding cooperation between the sliding column two 818 and the guiding groove 821. The connecting ring frame 82 drives the rotating cylinder 64 to rotate counterclockwise by a quarter of a circle by being connected to the connecting cylinder 81 and the connecting cylinder 81 being connected to the rotating cylinder 64. The rotating cylinder 64 drives the lifting plate 62 and the mounting seat 61 to rotate synchronously by being connected to the guiding groove plate 63 and the sliding cooperation between the guiding groove plate 63 and the lifting plate 62. At the same time, the corresponding sliding column one 621 corresponding to the milling cutter 71 drives the corresponding lifting plate 62 and the mounting seat 61 to move upward through the sliding cooperation with the right inclined area of the special-shaped ring groove 661 and the sliding cooperation with the sliding groove two 65. The corresponding sliding column one 621 corresponding to the grinding wheel 73 drives the corresponding lifting plate 62 and the mounting seat 61 to move downward through the sliding cooperation with the left inclined area of the special-shaped ring groove 661 and the sliding cooperation with the sliding groove two 65. The grinding wheel 73 can be rotated to directly above the workpiece 10 and below the mounting bracket 5. Then, the motor four 815 and the permanent magnet 88 are powered off. The spring 89 elongates and pushes the sliding rod 86 to move into the connecting cylinder 81. The sliding rod 86 realizes the meshing between the limit rack 85 and the toothed ring 84 by driving the limit rack 85 to move synchronously, thereby fixing the position of the mounting seat 61. The rotating assembly 2 polishes the surface of the workpiece 10 by driving the workpiece 10 to rotate and cooperating with the grinding wheel 73.
