Description

Technical Field

[0001] This invention relates to the field of motor manufacturing equipment technology, and in particular to a magnet insertion device. Background Technology

[0002] In motor manufacturing, inserting magnets is a critical process. Traditional manual magnet insertion methods pose a safety hazard because the magnets themselves are magnetic, causing them to easily fly out and injure operators. Furthermore, manual operation makes precise magnet positioning difficult, leading to misalignment and defective motors. This impacts production efficiency and product quality, failing to meet the demands of large-scale, high-quality motor production. Therefore, a safe, efficient magnet insertion device that ensures accurate magnet positioning is urgently needed. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to overcome the defects of the prior art and provide a safe, efficient magnet insertion device that can ensure accurate positioning of the magnet.

[0004] The technical solution adopted by this invention to solve its technical problem is: a magnet insertion device, comprising a magnet positioning plate, a sheath, a base, and a riveting assembly. The sheath is fixed on the base, and the rotor is placed in the cavity formed by the sheath and the base. The magnet positioning plate covers the sheath, and a magnet groove is formed on the magnet positioning plate for inserting a magnet.

[0005] The riveting assembly includes stacked rivet fixing plates and rubber pressure heads. The rivet fixing plates and rubber pressure heads are provided with communicating rivet head holes, and rivet heads are inserted into the rivet head holes.

[0006] After the magnet is inserted, the magnet positioning plate is removed, and the magnet end plate is installed on the rotor. The rivet head is riveted to the rivets evenly distributed on the magnet end plate, and the bottom end of the rivet is fixed to the bottom magnet end plate, thereby fixing the magnet.

[0007] Furthermore, the number, position, and angle of the magnetic steel grooves correspond to the magnetic steel.

[0008] Furthermore, the magnetic steel positioning plate is provided with magnetic steel markings, and the magnet is inserted according to the magnetic steel markings.

[0009] Furthermore, a cover plate is fixed above the sheath, which is used to fix the rivet fixing plate during riveting.

[0010] Furthermore, several locking blocks are inserted around the upper edge of the sheath. Each locking block includes a pressure block and a handle. The upper surface of the pressure block is flush with the upper surface of the sheath, and a limiting boss is provided below it. During the riveting process of the magnet, the handle is pushed so that the pressure block presses the magnet tightly to prevent the magnet from moving.

[0011] Furthermore, the number and position of the locking blocks correspond to the magnets.

[0012] Furthermore, a gap is maintained between the end face of the pressure block away from the handle and the edge of the magnet end plate.

[0013] The advantages of the magnet insertion device of the present invention are:

[0014] 1. Safe and reliable: The magnetic positioning plate guides the insertion of the magnet, preventing the magnet from flying out and injuring people due to magnetism, eliminating the safety hazards of manual insertion and ensuring the safety of operators.

[0015] 2. Precise positioning: The number, position, and angle of the magnetic slots on the magnetic positioning plate correspond to the magnetic steels. Magnetic markings can also be added to the magnetic steels to ensure accurate insertion, solving the problem of poor positioning during manual insertion, improving the quality of motor products, and reducing the production of defective products.

[0016] 3. High efficiency: With the help of the riveting assembly and riveting machine, the riveting and fixing of magnets and magnet end plates can be completed quickly. Compared with manual operation, the production efficiency of magnet insertion process is greatly improved, which is suitable for large-scale motor production.

[0017] 4. Stable structure: The cover plate on the top of the sheath can fix the rivet fixing plate, and the locking block can press the magnet to prevent movement, ensuring the stability of the riveting process and further improving the insertion quality and reliability.

[0024] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0025] As shown in the figure, a magnet insertion device includes a magnet positioning plate 1, a protective sleeve 7, a base 8, and a riveting assembly. The protective sleeve 7 is fixed on the base 8, and the rotor 4 is placed in the cavity formed by the protective sleeve 7 and the base 8. A cover plate 5 is fixed above the protective sleeve 7 and is used to fix the rivet fixing plate 2 during riveting.

[0026] Before inserting the magnet, the magnet positioning plate 1 covers the cover plate 5. The magnet positioning plate 1 has a magnet groove 13 and a magnet magnetic mark. The magnet 9 is inserted into the magnet groove 13 according to the magnet magnetic mark. The number, position and angle of the magnet groove 13 correspond to the magnet 9.

[0027] The riveting assembly includes a rivet fixing plate 2 stacked on top of each other and a rubber pressure head 3. The rivet fixing plate 2 and the rubber pressure head 3 are provided with communicating rivet head holes 12, and a rivet head is inserted into the rivet head hole 12.

[0028] After the magnet 9 is inserted, the magnet positioning plate 1 is removed, and the magnet end plate 10 is installed on the rotor 4. The rivet head is riveted to the rivets 11 evenly distributed on the magnet end plate 10, and the bottom end of the rivet 11 is fixed to the bottom magnet end plate.

[0029] Several locking blocks 6 are inserted into the circumference of the upper edge of the sheath 7, and the number and position of the locking blocks 6 correspond to the magnet 9.

[0030] In practice, the locking block 6 includes a pressure block 61 and a handle 62. The upper surface of the pressure block 61 is flush with the upper surface of the sheath 7, and a limiting boss 63 is provided below it. During the riveting process of the magnet 9, the handle 62 is pushed so that the pressure block 61 presses the magnet 9 tightly to prevent the magnet from moving. The end face of the pressure block 61 away from the handle 62 maintains a gap with the edge of the magnet end plate 10.

[0031] Before inserting the magnet, fix the sheath 7 on the base 8 so that the rotor 4 is placed in the cavity formed by the sheath 7 and the base 8; install the cover plate 5 on the sheath 7 at a suitable position for subsequent fixing of the rivet fixing plate 2.

[0032] Place the magnet positioning plate 1 over the sheath 7 at the corresponding angle. Based on the magnetic markings on the magnet, insert the magnet 9 into the corresponding position on the rotor through the magnet slot 13. After completion, remove the magnet positioning plate 1. This process uses the magnet positioning plate 1 to precisely guide the magnet 9, ensuring accurate installation of the magnet.

[0033] Assemble the riveting assembly by stacking the rivet fixing plate 2 and the rubber pressure head 3 on top of each other, ensuring that the rivet head holes 12 of the two are aligned, and insert the rivet head into the rivet head hole 12. Fit the magnet end plate 10 onto the rotor 4 with the magnet inserted, and adjust it to a suitable position so that the rivet 11 on the magnet end plate 10 corresponds to the rivet head.

[0034] Place the assembled riveting assembly above the magnet end plate 10, and then place the entire magnet insertion device on the riveting machine. The riveting machine first presses down on the riveting assembly, and pre-presses the rotor 4 through the rubber pressure head 3 to stabilize the position of each component; then the riveting machine continues to press down on the riveting head, so that the riveting head is riveted to the rivet 11 on the magnet end plate 10 to fix the magnet.

[0035] Before riveting, the handle 62 of the locking block 6 can be pushed, and the limiting boss 63 below the pressure block 61 can be used to press the magnet 9 with the upper surface of the pressure block 61 and the upper surface of the sheath 7. The end face of the pressure block 61 away from the handle 62 and the edge of the magnet end plate 10 are kept in a suitable gap to prevent the magnet from moving and ensure the stability of the riveting process.

[0036] Based on the above-described preferred embodiments of the present invention, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the inventive concept. The technical scope of this invention is not limited to the contents of the specification, but must be determined according to the scope of the claims.
