[0002] CNC lathe is one of the most widely used CNC machine tools at present. It is mainly used for cutting inner and outer cylindrical surfaces of shaft parts or disk parts, inner and outer conical surfaces of arbitrary taper angles, complex rotating inner and outer curved surfaces, and cylindrical and conical threads, and can perform grooving, drilling, reaming, reaming and boring, etc.

[0003] In a CNC lathe processing clamping and positioning mechanism with the Chinese utility model patent application disclosure specification CN219379795U, although it can clamp workpieces of different shapes by driving the clamping head through an electric cylinder, after clamping the workpiece, the housing can be rotated by the cooperation of the motor and the worm gear reducer. When the housing rotates, the wire of the electric cylinder will be pulled out from the outside of the wire wheel, and the spring will be wound at the same time. When the housing rotates in the opposite direction and resets, the spring can be used to reset the wire wheel and wind up the wire, thereby ensuring the advantage of stable use of the electric cylinder.

[0024] In this embodiment, preferably, the limiting mechanism includes a protrusion 9, a connecting plate 10, a first movable groove 11, a second movable groove 12 and a connecting rod 13. The protrusions 9 are fixedly arranged on both sides of the mounting block 4, and the connecting plates 10 are fixedly arranged on both sides of the mounting block 4. The connecting plate 10 is provided with a first movable groove 11 on the side close to the protrusion 9, and the protrusion 9 is movably arranged inside the first movable groove 11. The connecting plate 10 is movably arranged on one side of the slide rail 5 through a rotating shaft, and a second movable groove 12 is opened at the top of the connecting plate 10. A connecting rod 13 is movably arranged inside the slider 6 through a movable hole, and the connecting rod 13 is movably arranged inside the second movable groove 12;

[0025] Through the above solution, the slider 6 can be moved on the slide rail 5, which is convenient for fixing the object, and the operation mode is simple;

[0026] In this embodiment, preferably, the mounting mechanism includes a clamping block 14, a clamping slot 15, a mounting slot 16, a telescopic rod 17, a spring 18 and a limit block 19. The clamping block 8 is fixedly provided with a clamping block 14 on one side close to the fixed block 7. The fixed block 7 is provided with a clamping slot 15 on one side close to the clamping block 14. The clamping block 14 is movably arranged inside the clamping slot 15. The mounting slots 16 are provided on both sides of the clamping slot 15. The telescopic rod 17 is movably arranged inside the mounting slot 16. The surface of the telescopic rod 17 is sleeved with a spring 18. The telescopic rod 17 is fixedly provided with a limit block 19 on one end close to the clamping block 14.

[0027] Through the above scheme, the clamp block 8 can be disassembled and replaced, and can meet the needs of fixing objects of different sizes and models, thereby improving the practicality of the device;

[0028] In this embodiment, preferably, support frames 20 are fixedly provided on both sides of the top of the base 1, and an operating panel 21 is fixedly provided on the top of the support frame 20;

[0029] Through the above solution, by using the operating plate 21 and the support frame 20, it is convenient to process the objects on the operating plate 21, and prevent the processed objects from falling into the receiving tank 2, causing waste of resources;

[0030] In this embodiment, preferably, brackets 22 are fixedly provided at both ends of the bottom side of the base 1;

[0031] Through the above solution, the base 1 can be supported by using the bracket 22, so as to facilitate the installation of the telescopic motor 3;

[0033] Through the above solution, one side of the limit opening 19 is set in a trapezoidal shape, which can better limit and fix the block 14 model;

[0034] When a CNC lathe processing positioning mechanism of the present embodiment is used, first, the object to be processed is placed on the operating table, and the telescopic motor 3 is driven to work, driving the mounting block 4 to perform lifting and lowering movements. Because protrusions 9 are fixedly provided on both sides of the mounting block 4, and the protrusions 9 are movably provided inside the first movable groove 11, when the mounting block 4 moves, the connecting plate 10 is driven to move, because the connecting plate 10 and the slider 6 are movably connected by the connecting rod 13, so that the slider 6 moves toward the middle on the slide rail 5, and the clamping block 8 fixes the object at this time, which is convenient for processing the object; when the object processing is completed, the telescopic motor 3 is driven to move, so that the mounting block 4 is moved downward, driving the connecting rod 13 to move, so that the slider 6 moves to both ends on the slide rail 5, and the clamping block 8 moves to both ends, and the object can be processed. The items are taken out; and the clamping block 8 can be disassembled and replaced to fix items of different sizes. When the clamping block 8 is replaced, the clamping block 8 is first pushed outward, and the clamping block 14 moves outward at this time. When the clamping block 14 passes the limit block 19, the limit block 19 is squeezed, so that the limit block 19 moves to both ends and the spring 18 is squeezed. When the clamping block 14 leaves the inside of the card slot 15, the limit block 19 is returned to its original position by the rebound force of the spring 18, and the removed clamping block 8 is replaced; during installation, the clamping block 14 is inserted into the card slot 15. At this time, the clamping block 14 squeezes the limit block 19 inside the card slot 15, so that the limit block 19 moves toward the inside of the installation slot 16. When the clamping block 14 is stuck in the inside of the card slot 15, the limit block 19 returns to its original position by the rebound force of the spring 18, and the clamping block 14 is limited and fixed.
