Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

Therefore, they should not be construed as limitations on this utility model.

[0028] Please see Figure 1-2 This utility model provides a technical solution: an adaptive positioning structure for machining oil valve parts, comprising:

[0029] Workbench 1;

[0030] The central positioning component 2 is positioned in the middle of the worktable 1, and the clamping component 3 is mounted on it;

[0031] Several edge positioning elements 4 are eccentrically rotatably connected to a rotating shaft 5 on the outside of the worktable 1;

[0032] Several closed linkage components 6 are driven by the drive structure on the worktable 1, and are movably disposed on the outside of the corresponding edge positioning component 4 and abut against the edge positioning component 4.

[0033] The top of the central positioning component 2 is provided with a stud, which is screwed into the internal thread on the inner side of the clamping component 3. This ensures that the clamping component 3 clamps and vertically limits the oil valve parts.

[0034] A torsion spring is fitted on the rotating shaft 5, and the end of the torsion spring is connected to the edge positioning member 4 and the rotating shaft 5, so that after the processing is completed and the closing linkage member 6 moves outward and resets, the edge positioning member 4 can automatically rotate and disengage from the part, so that the part can be removed.

[0035] The closed linkage 6 has a V-shaped structure. The driving structure is arranged in the mounting groove 7 of the worktable 1. The top of the mounting groove 7 has an opening 8 extending to the outside of the worktable 1. The bottom of the closed linkage 6 is connected to the inner slide block 10 through a connecting block 9. The connecting block 9 is slidably arranged in the opening 8. The inner slide block 10 is slidably arranged in the mounting groove 7. The driving structure includes a rack 11, a gear 12, and a servo motor 13. The rack 11 is positioned inside the inner slide block 10. The gear 12 meshes with the rack 11 and is driven by the output shaft of the servo motor 13, rotating within the mounting groove 7. A guide rail is provided in the mounting groove 7, slidably connected to the rack 11. Several racks 11 are connected to a single gear 12. This allows the closed linkage 6 to synchronously push multiple edge positioning parts 4, completing adaptive clamping and positioning of parts, simplifying the structure and reducing structural complexity.

[0036] The working principle of the adaptive positioning structure for processing oil valve parts in this embodiment includes: This positioning structure is used for positioning polygonal ring-shaped oil valve parts such as valve handwheels during processing. In use, the part is first placed on the central positioning component 2, and the clamping component 3 is screwed onto the central positioning component 2 to press down and vertically position the part (at this time, the part can rotate). Then, the servo motor 13 drives the gear 12 to rotate, which in turn drives the rack 11 and the inner slide 10 to move. Each closed linkage component 6 converges inward and pushes the side of the corresponding edge positioning component 4, causing it to rotate and adaptively abut against the side of the part. This restricts the rotation of the part, achieving adaptive clamping and positioning of parts of different shapes and sizes, improving adaptability and positioning stability. After processing, the closed linkage component 6 moves outward to reset, and the edge positioning component 4 rotates outward under the elastic force of the torsion spring, disengaging from the part. Then, the clamping component 3 is removed, and the part can be taken out.

[0037] In summary, due to the adoption of the above technical solution, the adaptive positioning structure for machining oil valve parts in this embodiment has the following advantages compared with the prior art:

[0038] The positioning structure of this utility model is used for positioning polygonal ring-shaped oil valve parts such as valve handwheels during processing. Through the central positioning component and clamping component, the vertical positioning of the part can be achieved. Several edge positioning components eccentrically rotated on the rotating shaft, together with the closed linkage component and drive structure, can achieve adaptive clamping and positioning of parts of different shapes and sizes, improving adaptability and positioning stability.

[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
