Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] like Figures 2 to 7 As shown, a rotatable precision machining table, the structure of which includes a machining table body 1. The control box 2 in this embodiment is arranged at the lower end of the machining table body 1, the machining table body 1 is rotatably connected to the control box 2, and the coarse adjustment structure and the fine adjustment structure are both arranged in the control cavity. Among them, the coarse adjustment structure is used to quickly adjust the rotation angle of the machining table body 1, and the fine adjustment structure is used to accurately adjust the rotation angle of the machining table body 1. A switching structure is arranged in the control box 2, which is used to change the coarse adjustment structure to control the rotation of the machining table body 1 to the fine adjustment structure to control the rotation of the machining table body 1, or to change the fine adjustment structure to control the rotation of the machining table body 1 to the coarse adjustment structure to control the rotation of the machining table body 1.

[0031] The coarse adjustment structure in this embodiment includes a rotating gear 6, which is fixedly connected to the processing table body 1. The rotating gear 6 is disposed in the control box 2 and is rotationally connected to the control box 2. A sliding rail 71 is fixedly disposed in the control box 2, a first sliding groove 711 is disposed in the sliding rail 71, and a sliding rack 7 is slidably disposed in the first sliding groove 711. The sliding rack 7 is meshed with the rotating gear 6. In this embodiment, the rotating gear 6 is rotated by moving the sliding rack 7, thereby achieving the purpose of quickly adjusting the rotation angle of the processing table body 1.

[0032] In the fine adjustment structure of the present embodiment, the fine adjustment member 82 has a first limiting hole 72 provided at the end of the sliding rack 7, a first rotating hole 721 provided on the inner wall of the first limiting hole 72, a first adjusting screw 3 rotatably provided in the first rotating hole 721, a first limiting bolt 32 fixedly provided at the end of the first adjusting screw 3, the first limiting bolt 32 provided in the first limiting hole 72, an adjusting groove 821 provided on the fine adjustment member 82, and the adjusting groove 821 being threadedly connected to the first adjusting screw 3. With this design, when the sliding groove on the fine adjustment member 82 is threadedly connected to the first adjusting screw 3, the sliding rack 7 can be moved by rotating the first adjusting screw 3. In this embodiment, the rotation angle of the processing table body 1 is precisely controlled by increasing the rotation stroke of the first adjusting screw 3, ensuring that the processing table body 1 reaches the preset rotation angle more accurately.

[0033] In this embodiment, the cross-section of the first sliding groove 711 is a "convex" structure. The limiting member 73 is fixedly arranged on both sides of the sliding rack 7. The sliding rack 7 is slidably connected to the first sliding groove 711 through the limiting member 73. Such a design ensures that the sliding rack 7 slides smoothly in the first sliding groove 711, and it is not easy for the sliding rack 7 to be displaced during the sliding process.

[0034] The switching structure in this embodiment includes a first adjusting screw 3. The fixing member 81 is fixedly arranged in the control box 2. A second sliding groove 811 is arranged on the fixing member 81. The second sliding groove 811 is slidably connected to the first adjusting screw 3. The fine-tuning member 82 is arranged between the fixing member 81 and the inner wall of the control box 2 and is slidably connected to the fixing member 81. A second limiting hole 822 is arranged on the fine-tuning member 82. A second rotating hole 8221 is arranged on the side wall of the second limiting hole 822. The first adjusting screw 3 is rotatably connected to the second rotating hole 8221. A second limiting bolt 51 is arranged in the second rotating hole 8221. The second limiting bolt 51 is fixedly connected to the second adjusting screw 5. The second adjusting screw 5 is threadedly connected to the control box 2. Such a design realizes the meshing of the fine-tuning member 82 and the first adjusting screw 3 by rotating the second adjusting screw 5, so as to accurately adjust the rotation angle of the processing table body 1. When the second adjusting screw 5 is rotated to make the fine-tuning member 82 move away from the first adjusting screw 3 end, the rotation angle of the processing table body 1 can be quickly adjusted by directly moving the first adjusting screw 3. In this embodiment, the processing table can be first rotated to a position near the workpiece to be processed by moving the first adjusting bolt, and then the rotation angle can be made more accurate by meshing with the fine-tuning member 82 and rotating the first adjusting bolt.

[0035] The first connecting column 91 and the second connecting column 92 in this embodiment are arranged between the fixing member 81 and the control box 2. The first connecting column 91 and the second connecting column 92 are parallel to each other. The fine-tuning member 82 is slidably connected to both the first connecting column 91 and the second connecting column 92 at the same time. Through the mutually parallel first connecting column 91 and second connecting column 92, it is ensured that the fine-tuning member 82 is not easy to be displaced during the sliding process.

[0036] In this embodiment, the cross-section of the processing table body 1 is a "冂" - shaped structure. The locking plate 11 is slidably arranged on the processing table body 1. A limiting groove 111 is arranged on the locking plate 11. A third rotating hole 112 is arranged on the inner wall of the limiting groove 111. The third adjusting screw 4 is threadedly connected to the processing table body 1. The third adjusting screw 4 is rotatably connected to the third rotating hole 112. A third limiting bolt 41 is arranged in the limiting groove 111. The third limiting bolt 41 is fixedly connected to the third adjusting screw 4. Such a design is to ensure that when the workpiece to be processed enters the processing table body 1, the locking plate 11 can be clamped and fixed to the workpiece to be processed by rotating the third adjusting screw 4. Ensure that the workpiece to be processed is more stable during rotation or processing, and it is not easy for the workpiece to be processed to脱离 the processing table body 1.

[0037] In this embodiment, the rotating disk 31 is fixedly mounted at the end of the first adjusting screw 3 away from the fixing member 81, and the rotating handle 311 is fixedly mounted on the rotating disk 31. The rotating disk 31 in this embodiment is designed to facilitate movement of the first adjusting screw 3. The rotating handle 311 is designed to facilitate rotation of the rotating disk 31.

[0038] The working process of this embodiment is as follows: first, place the workpiece to be processed on the processing table body 1, then lock and fix the workpiece to be processed by rotating the third adjusting screw 4, then rotate the second adjusting screw 5 to disengage the fine-adjusting part 82 from the first adjusting screw 3, then move the first adjusting screw 3 or directly rotate the processing table body 1 so that the processing table body 1 is rotated to the vicinity of the position to be processed, then rotate the third adjusting screw 4 in the opposite direction to thread the fine-adjusting part 82 into the first adjusting screw 3, and finally drive the first adjusting screw 3 to rotate by rotating the handle 311 to achieve the precise adjustment of the processing table to the position to be processed.
