[0019] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0020] 1. In this utility model, a PP annular shell is used to place large annular parts. Steel needles and polishing fluid are placed inside the PP annular shell. The magnetic field conversion mechanism causes the steel needles to move at high speed in the polishing fluid and impact the parts, which plays a role in precision grinding and polishing. The turntable mechanism drives multiple sets of magnetic field conversion mechanisms to generate position changes, so that the magnetic field distribution of the magnetic field conversion mechanism acts on various positions of the PP annular shell, thereby ensuring that the grinding effect of the parts is uniform.

[0021] 2. In this utility model, the first gear motor rotates to drive the gear to rotate. Under the meshing action of the gear and the slewing bearing, the first turntable rotates, thereby switching multiple sets of magnetic field conversion mechanisms to alternately act on different positions of the PP annular shell. During magnetic grinding, steel needles and grinding fluid are placed inside the PP annular shell. Multiple sets of magnetic field conversion mechanisms alternately act on the steel needles, thereby alternately grinding the parts and ensuring that the grinding effect of the parts is uniform.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figure 1-5 This utility model provides a technical solution: an ultra-precision grinding device for aircraft parts manufacturing, comprising:

[0032] Fixture 1;

[0033] PP annular shell 2, which is snapped onto the fixing frame 1;

[0034] The turntable mechanism 3 is fixedly connected to the fixed frame 1, and the turntable mechanism 3 is located below the PP annular shell 2;

[0035] Multiple magnetic field conversion mechanisms 4 are disposed on the turntable mechanism 3 and attached to the bottom of the PP annular shell 2, and the multiple magnetic field conversion mechanisms 4 are arranged in a ring array along the axis of the PP annular shell 2.

[0036] The turntable mechanism 3 includes a bracket 31, a first reduction motor 32, and a first turntable 33. The bracket 31 is fixedly connected to the fixed frame 1. The first turntable 33 is connected to the bracket 31 through a slewing bearing 5. The first reduction motor 32 is fixed to the bracket 31. The output end of the first reduction motor 32 drives the slewing bearing 5 through a gear 6. The rotation of the first reduction motor 32 drives the gear 6 to rotate. Under the meshing action of the gear 6 and the slewing bearing 5, the first turntable 33 rotates, thereby switching multiple sets of magnetic field conversion mechanisms 4 to alternately act on different positions of the PP annular shell 2. During magnetic grinding, steel needles and grinding fluid are placed inside the PP annular shell 2. Multiple sets of magnetic field conversion mechanisms 4 alternately act on the steel needles, thereby alternately grinding the parts and ensuring that the grinding effect of the parts is uniform.

[0037] The magnetic field transformation mechanism 4 includes a second reduction motor 41, a second turntable 42, and multiple magnetic blocks 43. The second reduction motor 41 is fixedly connected to the first turntable 33, and the second turntable 42 is fixedly connected to the output end of the second reduction motor 41. The multiple magnetic blocks 43 are fixedly connected to the second turntable 42 and fit against the PP annular shell 2. The multiple magnetic blocks 43 are arranged in a circular array along the axis of the second turntable 42. The rotation of the second reduction motor 41 drives the turntable to rotate, and the rotation of the turntable changes the position of the multiple magnetic blocks 43, thereby causing the magnetic field of the multiple magnetic blocks 43 to change continuously. During magnetic grinding, steel needles and grinding fluid are placed inside the PP annular shell 2. The change in magnetic field causes the steel needles to move at high speed in the grinding fluid and impact the parts, achieving the effect of precision grinding and polishing.

[0038] The PP annular shell 2 has multiple slots 7, and a partition 8 is snapped into the slot 7. The partition 8 can divide the inside of the PP annular shell 2 into multiple areas, effectively preventing the magnetic needle from moving around in multiple areas, ensuring that the parts in each area can be hit by a sufficient amount of magnetic needle. The slot 7 design can facilitate the disassembly and assembly of the partition 8.

[0039] The partition 8 is provided with a clearance groove 9 and a handle position 10. The clearance groove 9 can avoid the location of the parts inside the PP annular shell 2, and the handle position 10 is convenient for installing and disassembling the partition 8.

[0040] Working principle: First, a large annular part is placed into the PP annular shell 2. Holding the handle 10 of the partition 8, the partition 8 is inserted into the slot 7, dividing the PP annular shell 2 into multiple areas. The large annular part is located in the clearance groove 9 of the partition 8. Steel needles and polishing fluid are placed in each area. Second, the second reduction motor 41 rotates, driving the turntable to rotate. The rotation of the turntable changes the position of multiple magnetic blocks 43, thereby causing the magnetic field of the multiple magnetic blocks 43 to change continuously. The change of magnetic field causes the steel needles to move at high speed in the polishing fluid and impact the part, achieving the effect of precision grinding and polishing. Finally, the first reduction motor 32 rotates, driving the gear 6 to rotate. Under the meshing action of the gear 6 and the slewing bearing 5, the first turntable 33 rotates, thereby switching multiple sets of magnetic field transformation mechanisms 4 to alternately act on different positions of the PP annular shell 2. The multiple sets of magnetic field transformation mechanisms 4 alternately act on the steel needles, thereby alternately grinding the part, thus ensuring the uniform grinding effect of the part.

[0041] 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.
