Detailed Implementation

[0021] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0022] like Figures 1 to 3 As shown in this embodiment, a direct-drive cutting mechanism includes a support base 1, a lifting platform 2, a moving platform 3, a three-phase asynchronous motor 4, a vertical servo motor 5, and a horizontal servo motor 6. Both the vertical servo motor 5 and the horizontal servo motor 6 are fixed to the support base 1. The drive end of the vertical servo motor 5 is connected to a vertical ball screw 7. A vertical ball nut 8 is installed on the lifting platform 2, and the vertical ball screw 7 and the vertical ball nut 8 are threadedly connected. The lifting platform 2 slides vertically on the support base 1. The drive end of the horizontal servo motor 6 is connected to a horizontal ball screw 9. A horizontal ball nut 10 is installed on the moving platform 3, and the horizontal ball screw 9 and the horizontal ball nut 10 are threadedly connected. The moving platform 3 slides horizontally on the support base 1. The three-phase asynchronous motor 4 is fixed to the moving platform 3, and its drive end is directly connected to a cutter shaft 11.

[0023] In terms of specific structure, a vertical linear slider 12 and a horizontal linear guide rail 13 are fixed on the support base 1; a vertical linear guide rail 14 is fixed on the lifting platform 2; and a horizontal linear slider 15 is fixed on the moving platform 3. The vertical linear slider 12 slides on the vertical linear guide rail 14, and the horizontal linear slider 15 slides on the horizontal linear guide rail 13. A vertical lead screw bearing 16 and a horizontal lead screw bearing 17 are fixed on the support base 1. The end of the vertical ball screw 7 is connected to the vertical lead screw bearing 16, and the end of the horizontal ball screw 9 is connected to the horizontal lead screw bearing 17. The two ends of the vertical lead screw bearing 16 and... Both ends of the horizontal ball screw bearing 17 are fitted with snap rings 18. A coupling 19 connects the cutter shaft 11 to the three-phase asynchronous motor 4. Round nuts 20 are connected to the rear ends of the cutter shaft 11, the vertical ball screw 7, and the horizontal ball screw 9. Angular contact bearings 21 are installed on the support base 1, the lifting platform 2, and the moving platform 3. The cutter shaft 11, the vertical ball screw 7, and the horizontal ball screw 9 all rotate within the angular contact bearings 21. An oil seal 22 is installed on the outer side of the angular contact bearings 21. Servo gearboxes 23 are connected to the drive ends of the vertical servo motor 5 and the horizontal servo motor 6.

[0024] When adjusting the cutting width position, the horizontal servo motor 6 controls the rotation of the horizontal ball screw 9. The threaded transmission moving table 3 with the horizontal ball nut 10 moves along the horizontal linear guide rail 13, controlling the three-phase asynchronous motor 4 on the moving table 3 to move left and right. The three-phase asynchronous motor 4 controls the tool connected to the tool shaft 11 to move horizontally and adjust the position for cutting. This design changes the traditional method of relying on belt drive to rotate the tool. Direct drive cutting is used in this design, which improves accuracy and meets customer needs.

[0025] Since different strips have different thicknesses, the vertical servo motor 5 controls the rotation of the vertical ball screw 7, and the lifting platform 2 with the vertical ball nut 8 is raised and lowered along the vertical linear guide rail 14 by the threaded drive, so that the height of the strip changes, and strips of different thicknesses can also be processed in this cutting mechanism.

[0026] It should be stated that the above-described specific embodiments are merely preferred embodiments of this utility model and the technical principles applied thereto. Within the scope of the technology disclosed in this utility model, any variations or substitutions that are easily conceived by those skilled in the art should be covered within the protection scope of this utility model.
