Description

Technical Field

[0001] This application relates to the field of motor stator end plate processing technology, and in particular to an automatic stator end plate flanging and hot riveting machine. Background Technology

[0002] In the production process of motor stator end plates, flanging and riveting are key processes that directly affect the assembly quality and performance of the stator. Traditional manual flanging and riveting methods suffer from low efficiency and poor consistency, making it difficult to meet the high precision and high efficiency requirements of modern motor production. With the development of automation technology, more and more companies are seeking automation solutions to improve production efficiency and product quality.

[0003] In existing technologies, the flanging of stator end plates is usually done manually. The product is placed on a tooling and hot-melt flanging is started. This flanging method will cause burrs at the product opening, which need to be scraped off.

[0004] Regarding the aforementioned technologies, the existing technology involves placing the product on a tooling fixture and starting the hot-melt flanging process, which results in burrs at the product's opening. This requires burr removal, which is time-consuming and labor-intensive, thus affecting production efficiency. Summary of the Invention

[0005] To address the issue that placing products on tooling and initiating hot-melt flanging results in burrs at the product's opening, requiring scraping to remove the burrs, which is time-consuming and labor-intensive and thus affects production efficiency, this application provides an automatic stator end plate flanging hot riveting machine.

[0006] This application provides an automatic flanging and hot riveting machine for stator end plates, which adopts the following technical solution: An automatic stator end plate flanging hot riveting machine includes a support frame for overall support. A pneumatic compressor for driving the equipment is provided on the top of the support frame. A mounting base is provided on the output end of the pneumatic compressor. A hot riveting head for flanging the stator end plate is connected to the end of the mounting base away from the pneumatic compressor. A protrusion that mates with the stator end plate is provided on the side of the hot riveting head away from the mounting base. A positioning seat for placing the stator is provided directly below the hot riveting head. The bottom of the positioning seat is connected to the support frame.

[0007] By adopting the above technical solution, a pneumatic compressor drives a hot riveting head to press and rivet the stator end plate on the positioning seat. This ensures that the pressure applied by the hot riveting head and the protrusions on the hot riveting head is uniform and consistent when in contact with the stator end plate. Combined with the hot riveting process, the end plate can be firmly riveted, reducing product quality fluctuations caused by unstable pressure. This enables the stator end plate to be automatically riveted, reducing the generation of burrs after the stator end plate is riveted, reducing manual operation steps, and helping to improve production efficiency and reduce labor costs.

[0008] Preferably, the connection between the mounting base and the output end of the air compressor is detachable, and the output end of the air compressor is located inside the mounting base.

[0009] By adopting the above technical solution and through the detachable design between the mounting base and the air compressor, the mounting base and the hot riveting head connected to it can be quickly disassembled and replaced. When it is necessary to adapt to stator end plates of different specifications, the corresponding size hot riveting head assembly can be replaced efficiently, reducing equipment adjustment time.

[0010] Preferably, the connection between the bottom of the mounting base and the hot riveting head is a detachable connection, and the top of the hot riveting head fits against the bottom of the mounting base.

[0011] By adopting the above technical solution, and by making the hot riveting head and the mounting base detachable, it is possible to quickly replace hot riveting heads of different specifications and shapes. It can flexibly adapt to the hot riveting requirements of various stator end plates without replacing the entire mounting base or drive components. This can greatly improve the equipment's compatibility with different products and reduce the cost of changing models.

[0012] Preferably, the hot riveting head and the side of the hot riveting head that contacts the stator end plate are both treated with an arc-shaped chamfer.

[0013] By adopting the above technical solution, the hot riveting head and the protrusion on the hot riveting head are chamfered with an arc shape to avoid rigid contact between the right angle or sharp edge of the hot riveting head and the stator end plate. This can effectively reduce the risk of cracking, deformation or scratching of the stator end plate edge due to pressure concentration during the hot riveting process, protect the integrity of the surface and structure of the stator end plate, and reduce the generation of burrs.

[0014] Preferably, the connection between the positioning seat and the support frame is a detachable connection, and the positioning seat is fixed to the support frame by bolts.

[0015] By adopting the above technical solution, the positioning seat can be detachably connected by bolts, which facilitates the quick replacement of the corresponding size positioning seat according to different stator specifications without the need to modify the support frame. This greatly shortens the equipment adjustment time when changing products, improves the flexibility of the production line, and can better adapt to diversified production needs.

[0016] Preferably, the support frame includes a base plate, a pair of support columns and a top plate. The bottom end of the support column is fixedly connected to the base plate, and the surface of the support column is provided with threads. The top plate is fixed to the support column by a nut engaging with the threads on the support column.

[0017] By adopting the above technical solution, the top plate is fixed by the threaded nuts on the surface of the support column. The height of the top plate can be flexibly adjusted by rotating the nuts, thereby adjusting the height of the support frame. This allows for adjustment of the distance between the positioning seat and the hot riveting head, enabling precise matching of stators and stator end plates of different thicknesses and specifications, meeting diverse hot riveting processes, and improving the versatility of the equipment.

[0018] Preferably, the top plate is provided with an intelligent controller for controlling the operation of the air compressor, and the intelligent controller is electrically connected to the air compressor.

[0019] By adopting the above technical solution and setting up an intelligent controller, the output pressure, working stroke, action speed and start-stop timing of the pneumatic compressor can be precisely adjusted to ensure that the pressure and movement trajectory of the hot riveting head meet the process standards, reduce the error of manual operation, and improve the consistency and pass rate of hot riveting of stator end plates.

[0020] In summary, this application includes at least one of the following beneficial technical effects: 1. By designing a hot riveting head structure and cooperating with a pneumatic press, the automatic flanging function of the stator end plate is realized, enabling the stator end plate to be flanged in one go. This shortens the hot melting time, reduces the generation of burrs after flanging the stator end plate, and reduces manual operation steps, which helps to improve production efficiency and reduce labor costs. 2. The hot riveting head and the protrusions on the hot riveting head are chamfered to avoid rigid contact between the right angle or sharp edge of the hot riveting head and the stator end plate, thus protecting the integrity of the surface and structure of the stator end plate and reducing the generation of burrs. 3. The top plate is fixed by the threaded nuts on the surface of the support column. The height of the top plate can be flexibly adjusted by rotating the nuts, thereby adjusting the height of the support frame. This allows for adjustment of the distance between the positioning seat and the hot riveting head, enabling precise matching of stators and stator end plates of different thicknesses and specifications, meeting diverse hot riveting processes, and improving the versatility of the equipment.

[0023] The following is in conjunction with the appendix Figure 1 -Appendix Figure 4 This application will be described in further detail.

[0024] This application discloses an automatic hot riveting machine for stator end plates.

[0025] Reference Figures 1 to 4 An automatic stator end plate flanging and hot riveting machine includes a support frame 1 and a pneumatic compressor 2. The support frame 1 supports the entire machine and ensures its stability. The pneumatic compressor 2 is bolted to the top of the support frame 1, allowing the support frame 1 to support the pneumatic compressor 2. The output end of the pneumatic compressor 2 passes through the top plate 13 of the support frame 1. A mounting base 3 is bolted to the output end of the pneumatic compressor 2, allowing the mounting base 3 to be disassembled. The bottom end of the output end of the pneumatic compressor 2 is located inside the mounting base 3. A hot riveting head 4 is installed at the end of the mounting base 3 away from the air compressor 2. The hot riveting head 4 is circular in shape and has a slot. A protrusion 5 is provided on the side of the hot riveting head 4 away from the mounting base 3, so that the protrusion 5 cooperates with the stator end plate to fold the stator end plate. A positioning seat 6 for positioning the stator and stator end plate is provided directly below the hot riveting head 4. The bottom of the positioning seat 6 is connected to the support frame 1, so that the stator is placed on the positioning seat 6 and the positioning end plate is placed on the end of the stator near the hot riveting head 4.

[0026] The above method involves installing the stator on the positioning seat 6 and placing the stator end plate on the stator, thus positioning the stator and stator end plate on the positioning seat 6. Then, the pneumatic compressor 2 is started, which drives the mounting seat 3 to move. The mounting seat 3 then drives the hot riveting head 4 to move, so that the protrusion 5 and the bottom surface of the hot riveting head 4 come into contact with the stator end plate, causing the hot riveting head 4 to press the stator end plate and flanging it. Through the cooperation of the protrusion 5, the generation of burrs is reduced, and the stator end plate can be flanged in one go, improving production efficiency.

[0027] The connection between the positioning seat 6 and the support frame 1 is detachable, and the support frame 1 and the positioning seat 6 are fixed by bolts. The positioning seat 6 has four mounting holes that cooperate with the bolts, which are evenly distributed on the stator seat.

[0028] With the above solution, the positioning seat 6 is detachably connected by bolts, which makes it easy to quickly replace the positioning seat 6 of the corresponding size according to different stators without modifying the support frame 1. This greatly shortens the equipment adjustment time when changing products, improves the flexibility of the production line, and can better adapt to diversified production needs.

[0029] refer to Figure 1 The support frame 1 includes a base plate 11, a pair of support columns 12 and a top plate 13. The top of the base plate 11 is fixedly connected to the bottom of the pair of support columns 12, and the support columns 12 are symmetrically distributed on the base plate 11. Threads are provided on the upper surface of the support columns 12. The top plate 13 is fixed to the support columns 12 by nuts engaging with the threads on the support columns 12. The air compressor 2 is installed on the top plate, so that the top supports the air compressor 2. The mounting base 3, the hot riveting head 4 and the positioning base 6 are located between the top plate 13 and the base plate 11.

[0030] With the above solution, the top plate 13 is fixed by the threaded nut on the surface of the support column 12. The height of the top plate 13 can be flexibly adjusted by rotating the nut, thereby adjusting the height of the support frame 1. This allows for adjustment of the distance between the positioning seat 6 and the hot riveting head 4, enabling precise matching of stators and stator end plates of different thicknesses and specifications, meeting diverse hot riveting processes, and improving the versatility of the equipment.

[0031] A smart controller 7 is installed on the top of the support frame 1. The bottom of the smart controller 7 is fixed on the top plate 13. The smart controller 7 is connected to the air compressor 2 through wires, so that the smart controller 7 controls the operation of the air compressor 2. By setting the smart controller 7, the output pressure, working stroke, action speed and start and stop timing of the air compressor 2 can be precisely adjusted to ensure that the pressure and movement trajectory of the hot riveting head 4 meet the process standards, reduce the error of manual operation, and improve the consistency and pass rate of hot riveting of the stator end plate.

[0032] refer to Figure 2 and Figure 3 The connection between the hot riveting head 4 and the mounting base 3 is fixed by bolts, and the side of the hot riveting head 4 closest to the mounting base 3 is in contact with the mounting base 3, so that the hot riveting head 4 can be disassembled and the specifications of the hot riveting head 4 can be changed when needed.

[0033] By implementing the above solution, the hot riveting head 4 and the mounting base 3 can be detachably connected, allowing for quick replacement of hot riveting heads 4 of different specifications and shapes. This enables flexible adaptation to various stator end plate flanging hot riveting requirements without replacing the entire mounting base 3 or drive components, significantly improving the equipment's compatibility with different products and reducing changeover costs.

[0034] refer to Figure 3 and Figure 4The hot riveting head 4 and the protrusion 5 on the hot riveting head 4 are both arc-shaped on the side that contacts the stator end plate. This reduces the generation of burrs when the hot riveting head 4 presses down and flangs the stator end plate, and avoids rigid contact between the right angle or sharp edge of the hot riveting head 4 and the stator end plate. This effectively reduces the risk of cracking, deformation or scratching of the stator end plate edge due to pressure concentration during the hot riveting process, and protects the integrity of the surface and structure of the stator end plate.

[0035] The implementation principle of this application embodiment is as follows: In implementation, the stator is fixed on the positioning seat 6, and the stator end plate is placed on the top of the stator for positioning and fixing. Then, the hot riveting head 4 is aligned with the stator end plate. The air compressor 2 on the top of the support frame 1 is started by the intelligent controller 7. The air compressor 2 drives the mounting seat 3 to press down, and the mounting seat 3 drives the hot riveting head 4 to press down. The hot riveting head 4 and the protrusion 5 on the hot riveting head 4 press down on the stator end plate, so that the stator end plate is turned over. The stator end plate is turned over in one go, which reduces the generation of burrs and improves production efficiency. During implementation, when the support frame 1 needs to be adjusted according to the stator specifications, the nuts on the support column 12 are rotated, causing the nuts to move the top plate 13 between the two nuts upward or downward, which in turn causes the top plate 13 to move the air compressor 2, adjusting the distance between the hot riveting head 4 and the positioning seat 6, thus enabling it to be used for stator end plate flanging for other stator specifications.

[0036] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
