[0023] The utility model is further described in detail below based on the accompanying drawings and implementation cases.

[0024] The directional terms such as up, down, left, right, front, back, front, back, top, bottom, etc. mentioned or may be mentioned in this specification are defined relative to the structures shown in the drawings. The words "inside" and "outside" refer to the direction toward or away from the geometric center of a specific component, respectively. They are relative concepts, and therefore may change accordingly according to different locations and different usage conditions. Therefore, these or other directional terms should not be interpreted as restrictive terms.

[0025] This embodiment provides a processing device for the ring plate 3, referring to Figures 1 to 3 , including a rotary table 1 and at least one milling cutter assembly 2 for milling the annular surface of the ring plate 3, the rotary table 1 can rotate around its own axis, and at the same time, the rotary table 1 is arranged inside the ring plate 3 and is arranged concentrically with the ring plate 3, the rotary table 1 is connected to the milling cutter assembly 2 through the transmission assembly 4, and when the rotary table 1 rotates, it drives the milling cutter assembly 2 to make a circular motion around the center of the ring plate 3, so that the milling cutter assembly 2 can continuously and smoothly mill the ring plate 3, reducing the non-cutting time of the milling cutter assembly 2, thereby improving the processing efficiency. In this embodiment, the rotary table 11 is a structure with its own power source, such as a structure driven by a power device such as a hydraulic motor, a drive motor, etc. to rotate.

[0026] In this embodiment, the milling cutter assembly 2 includes a driving member 22 and a milling cutter 21 . The driving member can drive the milling cutter to rotate, that is, the high-speed rotating milling cutter contacts the annular surface of the ring plate 3 , thereby realizing the milling process of the ring plate 3 .

[0027] Furthermore, the transmission assembly 4 is arranged on the top of the rotary worktable 1 and is extended radially along the ring plate 3. On the one hand, the milling cutter assembly 2 can adapt to the ring plates 3 of different diameters by simply changing the position of the milling cutter assembly 2 on the transmission assembly 4, thereby processing the ring plates 3 of different sizes, thereby improving the processing flexibility and efficiency. On the other hand, the transmission assembly 4 extends radially along the ring plate 3, which can provide more stable support for the milling cutter assembly 2 and reduce vibration and deviation during the cutting process.

[0028] At the same time, in order to enable the milling cutter assembly 2 to contact a wider area of ​​the ring plate 3 and expand the processing range, the projections of the two ends of the transmission assembly 4 in the height direction of the ring plate 3 are both able to exceed the outer edge of the ring plate 3, so that the milling cutter assembly 2 can cover a larger area in a single processing, which helps to shorten the processing cycle and improve processing efficiency.

[0029] Furthermore, in order to improve the processing efficiency of the milling cutter assembly 2 on the ring plate 3, the number of the milling cutter assemblies 2 is set to two, and the two milling cutter assemblies 2 are symmetrically arranged at the two ends of the transmission assembly 4. When the rotary worktable 1 is working, the two milling cutter assemblies 2 can simultaneously perform milling processing on the annular surface of the ring plate 3 driven by the rotary worktable 1, which helps to improve the processing efficiency. At the same time, since the two milling cutter assemblies 2 are symmetrically arranged at the two ends of the transmission assembly 4, the transmission assembly 4 can maintain balance, thereby improving the structural stability of the transmission assembly 4 during rotation, which helps to improve the processing accuracy and processing quality.

[0030] In actual processing, since the single movement stroke of the milling cutter assembly 2 is limited, it cannot cover all the areas that need to be processed, that is, it is necessary to adjust the position of the milling cutter assembly 2 on the transmission assembly 4. In order to meet the processing requirements, a first drive assembly 7 is set on the transmission assembly 4. The first drive assembly 7 is connected to the milling cutter assembly 2, and the first drive assembly 7 can drive the milling cutter assembly 2 to move radially along the ring plate 3. At the same time, in order to ensure the processing accuracy, the first drive assembly needs to be able to accurately position the milling cutter assembly 2 at the processing position. In this embodiment, in order to ensure the accuracy of the movement of the milling cutter assembly 2, the first drive assembly 7 is a screw motor. The screw motor can realize accurate control and positioning of the transmission components. When installing the screw motor, it is sufficient to ensure that the screw can move radially along the ring plate 3.

[0031] Furthermore, a limiting assembly for limiting the moving path of the milling cutter assembly 2 is provided on the transmission assembly 4 to ensure the accuracy of the radial movement of the milling cutter assembly 2 along the ring plate 3. Specifically, the transmission assembly 4 includes two symmetrical and spaced support members 41, and the support members 41 are extended along the axial direction of the transmission assembly 4, and the limiting assembly includes two limiting grooves 42 symmetrically arranged on the two support members 41, respectively, and the limiting grooves 42 are extended radially along the ring plate 3. The milling cutter assembly 2 is slidably matched with the limiting grooves 42, and the moving path of the milling cutter assembly 2 is limited by the limiting grooves 42, thereby improving the accuracy of the milling cutter assembly 2 when moving.

[0032] In this embodiment, in order to facilitate the installation between the milling cutter assembly 2 and the transmission assembly 4, the milling cutter assembly 2 is set on the mounting frame 5, and sliding parts 51 are provided on both sides of the mounting frame 5. The two sliding parts 51 are respectively slidably connected to the two limiting slide grooves 42, and the first drive assembly 7 is transmission-connected to the mounting frame 5.

[0033] Furthermore, a second driving assembly 6 is arranged on the mounting frame 5. The second driving assembly 6 can be connected to the milling cutter assembly 2 and can drive the milling cutter to move repeatedly along the height direction of the ring plate 3, so that the processing depth of the milling cutter assembly 2 on the annular surface of the ring plate 3 can be changed, thereby meeting more processing requirements.

[0034] Finally, it should be noted that the above implementation cases are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the above implementation cases, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the above implementation cases, or replace some of the technical features therein with equivalents. These modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the implementation cases of the utility model.
