[0025] The base plate 1 serves as the fixed foundation for the worktable 2, and all components are ultimately fixed to the base plate 1. The worktable 2, fixed to the top of the base plate 1, is the main platform for carrying and supporting workpieces for processing. The rotary plate 10, located on top of the worktable 2, is the core component responsible for rotational movement. The workpiece can be rotated for processing by rotating the rotary plate 10. The adjustment mechanism consists of multiple slides 11, sliders 12, moving blocks 19, mounting slots 15, adjusting bolts 13, and replaceable components, allowing adjustment of the component positions within the rotary plate 10. Multiple slides 11 are provided inside the rotary plate 10, with sliders 12 slidably connected within each slide. The sliders 12 adjust the position of the clamping plate 17 through relative movement with the slides 11. Moving blocks 19 and mounting slots 15: Moving blocks 19 are fixedly connected to the top of the sliders 12, and mounting slots 15 are provided inside the moving blocks 19, with adjusting bolts 13 installed within the slots. The moving blocks 19 precisely adjust the clamping angle or position of the workpiece by adjusting the position of the adjusting bolts 13. Replacement Components: To accommodate different workpiece shapes, a replacement component is provided inside the mounting slot 15. The replacement component includes a mounting block 16, a connecting plate 18, and a clamping plate 17. The mounting block 16 is fixed by adjusting bolts 13, and workpieces of different shapes are fixed by the connecting plate 18 and the clamping plate 17, enabling quick fixture changes to meet the processing requirements of different workpieces.

[0026] Reference Figure 1 , Figure 2 and Figure 3 The worktable 2 is externally fixedly connected to a mounting box 3. The bottom of the mounting box 3 is fixedly connected to the top of the base plate 1. The mounting box 3 is externally fixedly connected to a power box 5. The output end of the power box 5 is fixedly connected to a limit block 6. The limit block 6 is externally provided with a limit guide rail 4. The limit guide rail 4 is externally fixedly connected to the inside of the mounting box 3. The limit block 6 is externally fixedly connected to a rack 7. The rack 7 is externally meshed with a gear 8. The gear 8 is internally fixedly connected to a boss 9. The boss 9 is externally rotatably connected to the inside of the worktable 2. The top of the boss 9 is fixedly connected to a rotating plate 10. The moving block 19 is internally threaded with limit bolts 14. The bottom end of the limit bolt 14 abuts against the top of the rotating plate 10.

[0027] Mounting box 3 and power box 5: The mounting box 3 is fixedly connected to the outside of the worktable 2, and the lower part of the mounting box 3 is fixedly connected to the base plate 1; the power box 5 provides power through pneumatic drive and controls the entire rotation process. Limiting block 6 and limiting guide rail 4: The output end of the power box 5 is fixedly connected to the limiting block 6, which is used to limit the range of rotational movement and ensure that the rotating plate 10 does not exceed the preset working range. The limiting block 6 is fixedly connected to the inside of the mounting box 3 through the limiting guide rail 4 to achieve precise limit control. Rack 7 and gear 8: The rack 7 is fixedly connected to the outside of the limiting block 6. The rack 7 meshes with the gear 8. The movement of the rack 7 is pneumatically controlled to drive the rotation of the gear 8. The rotation of the gear 8 will further drive the rotation of the boss 9. Boss 9 and rotating plate 10: The boss 9 is fixedly connected to the inside of the gear 8. The boss 9 drives the rotation of the rotating plate 10 by rotating. In this way, the power of the pneumatic system achieves the precise rotation of the rotating plate 10 through the synergistic action of the rack 7, gear 8 and boss 9. Precise control of the limiting bolt 14: Each moving block 19 is internally threaded with a limiting bolt 14, the bottom end of which contacts the top of the rotating plate 10 for the movement of the moving block 19.

[0028] Working Principle: In use, the mounting block 16 is removed from the mounting slot 15 by rotating the adjusting bolt 13. After removal, mounting blocks 16 with different types of fixtures are installed inside the mounting slot 15. This device is designed for easy installation and use. After installation, rotating the adjusting bolt 13 effectively restricts workpiece displacement, thereby ensuring machining accuracy and improving work efficiency. The modular fixture design can simultaneously accommodate workpieces of different shapes, exhibiting strong adaptability and a wide range of applications. Furthermore, the modular fixture reduces fixture change time, further improving machining efficiency.

[0029] Secondly, the movement of the limiting block 6 is driven by the power box 5. The rotation of the limiting block 6 drives the rack 7 to move, which in turn drives the gear 8 meshing with it to rotate. The rotation of the gear 8 then drives the boss 9 to rotate, and finally, the boss 9 drives the rotating plate 10 to rotate. The rotating plate 10 performs rotational processing on the clamped and fixed workpiece. Under the precise control of the power box 5, the workpiece can achieve higher processing accuracy during the processing, thereby effectively improving processing quality and work efficiency.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
