Description

Technical Field

[0001] This utility model relates to the field of magnetic sheet processing technology, and in particular to a high-efficiency processing tooling for permanent magnet ring electromagnetic sheets in new energy vehicle motors. Background Technology

[0002] Permanent magnet ring-shaped electromagnetic plates are an important component in permanent magnet motors for new energy vehicles. Permanent magnet motors are widely used in new energy vehicles. Their basic structure includes a stator and a rotor, with permanent magnets embedded inside the rotor. Permanent magnet ring-shaped electromagnetic plates are a type of permanent magnet.

[0003] The machining accuracy of the ring-shaped electromagnetic sheet directly affects the performance of the motor. In the current magnetic sheet machining process, there is a lack of specialized machining tooling, resulting in low machining efficiency and difficulty in guaranteeing accuracy, which in turn has a certain adverse effect on the performance of the permanent magnet motor.

[0004] Therefore, a new solution is needed to address the above problems. Summary of the Invention

[0005] This invention addresses the technical problem of low machining accuracy in annular electromagnetic sheets by providing a high-efficiency machining fixture for permanent magnet annular electromagnetic sheets in new energy vehicle motors, which improves machining accuracy by ensuring stability during the machining process.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a high-efficiency processing fixture for permanent magnet annular electromagnetic plates of new energy vehicle motors, including a fixed seat, on which a base is integrally formed, and an inner grinding sleeve is threadedly connected to the outer surface of the base. When processing the inner ring of the annular electromagnetic plate, the annular electromagnetic plate is placed on the base, and the inner grinding sleeve is simultaneously sleeved on the outside of the annular electromagnetic plate to keep the base and the annular electromagnetic plate relatively fixed. The fixed seat has a threaded hole, on which a bolt is threadedly connected, and an outer grinding pad is also clamped between the base and the bolt. When processing the outer ring of the annular electromagnetic plate, the annular electromagnetic plate is placed on the base and clamped and fixed to the base by the outer grinding pad.

[0007] Furthermore, the inner grinding sleeve is bent and formed with a constriction on the side away from the fixed seat, the constriction being used to abut against the annular electromagnetic plate.

[0008] Furthermore, multiple adjusting screws are radially mounted on the inner grinding sleeve, and these adjusting screws exert a clamping effect on the radial direction of the annular electromagnetic plate.

[0009] Furthermore, the edge of the outer grinding pad extends outward to form a pressing edge, which is used to abut against the annular electromagnetic sheet.

[0010] Compared with the prior art, the advantages of this utility model are:

[0011] The annular electromagnetic plate is clamped between the inner grinding sleeve and the base through the threaded connection between the inner grinding sleeve and the base, so that it can remain fixed and the inner ring is exposed during the grinding process, which is convenient for grinding the inner ring. The outer grinding pad clamps the annular electromagnetic plate with bolts, which exposes and fixes the outer ring, which is convenient for grinding the outer ring. Furthermore, the grinding part can be changed by simply replacing the inner grinding sleeve and the outer grinding pad during the grinding process. Attached Figure Description

[0016] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0017] like Figures 1 to 3 As shown, a high-efficiency machining fixture for permanent magnet annular electromagnetic plates in new energy vehicle motors includes a fixed base 1, on which a base 2 is integrally formed. An inner grinding sleeve 3 is threadedly connected to the base 2. When machining the inner ring of the annular electromagnetic plate 4, the annular electromagnetic plate 4 is placed on the base 2, and the inner grinding sleeve 3 is simultaneously fitted over the annular electromagnetic plate 4 to maintain a relative fixation between the base 2 and the annular electromagnetic plate 4. The threaded connection between the base 2 and the inner grinding sleeve 3 clamps the annular electromagnetic plate 4, thereby fixing it in place and ensuring that it does not move during the grinding and embedding process, thus guaranteeing the machining efficiency. The precision of the machining process can, to a certain extent, improve the quality of the annular electromagnetic sheet 4. The fixed base 1 has a threaded hole 11, and a bolt 5 is threaded onto the threaded hole 11. An outer grinding pad 6 is also held between the base 2 and the bolt 5. When machining the outer ring of the annular electromagnetic sheet 4, the annular electromagnetic sheet 4 is placed on the base 2 and fixed by the outer grinding pad 6. Similarly, the annular electromagnetic sheet 4 is placed between the outer grinding pad 6 and the fixed base 1, and the annular electromagnetic sheet 4 is kept fixed by the clamping action between the outer grinding pad 6 and the fixed base 1, thereby making the grinding process of the outer ring also have high precision.

[0018] The inner grinding sleeve 3 is bent on the side away from the fixed seat 1 and forms a narrowed opening 31. The narrowed opening 31 is used to abut against the annular electromagnetic plate 4. The abutment between the narrowed opening 31 and the annular electromagnetic plate 4 makes the fixing strength of the inner grinding sleeve 3 against the annular electromagnetic plate 4 higher. Multiple adjusting screws 32 are also radially installed on the inner grinding sleeve 3. The adjusting screws 32 form a clamping effect on the annular electromagnetic plate 4 in the radial direction, which is used to further strengthen the fixing strength of the annular electromagnetic plate 4.

[0019] The edge of the outer grinding pad 6 extends outward to form a pressing edge 61. The pressing edge 61 is used to abut against the annular electromagnetic sheet 4. The pressing edge 61 is used to expand the contact area, thereby reducing the pressure and thus protecting the annular electromagnetic sheet 4 to a certain extent.

[0020] The scope of protection of this utility model includes, but is not limited to, the above embodiments. The scope of protection of this utility model is defined by the claims. Any substitutions, modifications, or improvements to this technology that are easily conceived by those skilled in the art shall fall within the scope of protection of this utility model.
