Description

Technical Field

[0001] This utility model belongs to the field of motor stator assembly technology, and particularly relates to a motor stator housing device. Background Technology

[0002] The motor stator mounting device is a core specialized piece of equipment in the motor manufacturing and assembly process. Its main function is to precisely and stably assemble the pre-wound and stacked motor stator (the core component of the motor, composed of iron core, coils, etc.) into the motor housing (the external protective and fixing shell of the stator, usually made of metal), achieving a reliable connection between the stator and the housing. This lays the foundation for subsequent processes such as rotor assembly and end cover installation. It is widely used in the mass production of various motors, including single-phase asynchronous motors, three-phase asynchronous motors, and drive motors for new energy vehicles, and is a key piece of equipment to ensure motor assembly accuracy, efficiency, and product quality.

[0003] In the practical application of existing motor stator housing installation devices, the press-fit shaft is generally assembled onto the mounting plate using bolt connections. When production requirements change and the appropriate press-fit shaft needs to be replaced according to different specifications of the housing model, operators need to use special tools to disassemble and retighten the multiple bolts fixing the press-fit shaft one by one. This process is cumbersome and time-consuming, resulting in low efficiency of press-fit shaft replacement, affecting the continuous operation of the motor stator housing installation process, and thus reducing overall production efficiency. In view of this, we propose a motor stator housing installation device. Utility Model Content

An extrusion groove is formed on the inner wall of the second rotating groove; A fixing component is located inside the second rotating rod and is used to fix the second rotating rod.

[0008] In this technical solution, it is ensured that the user can control the two first rotating rods to rotate simultaneously.

[0009] In the above technical solution, the fixing component further includes: A chute is formed inside a second rotating rod and communicates with an extrusion groove. A third rotating groove communicating with the outside is formed on the inner wall of the chute. An extrusion block is slidably connected inside the chute and is located inside the extrusion groove and in contact with the inner wall of the extrusion groove. A threaded rod is threadedly connected inside the extrusion block. One end of the threaded rod is fixedly connected to a third rotating rod, and one end of the third rotating rod passes through the third rotating groove and extends to the outside to be rotatably connected to the second rotating rod.

[0010] In this technical solution, the second rotating rod is ensured to remain in the preset position and cannot rotate, which further increases the stability of the press-fit shaft installation.

[0015] The beneficial effects of this utility model are: 1. This motor stator housing insertion device, through its threaded groove, first rotating rod, and bolts, allows the press-fit shaft to be installed in the inner cavity of the mounting plate. The positioning groove and positioning plate ensure the press-fit shaft is accurately positioned within the mounting plate's inner cavity. A first bevel gear, second bevel gear, third bevel gear, fourth bevel gear, connecting rod, and second rotating rod allow the two first rotating rods to rotate simultaneously, each driving one of the two bolts to rotate simultaneously. This structural design optimizes the fixing method of the press-fit shaft, eliminating the tedious operation of disassembling and retightening multiple fixing bolts one by one during traditional replacement processes. This significantly simplifies the operation process, effectively shortens the time required for each step, and significantly improves the replacement efficiency of the press-fit shaft. It also reduces downtime caused by model changes, ultimately facilitating the continuous and efficient execution of the motor stator housing insertion process and promoting overall production efficiency improvement.

[0016] 2. This motor stator housing insertion device, through the setting of an extrusion groove, an extrusion block, a threaded rod, and a third rotating rod, allows the extrusion block to move along the extrusion groove and extrude the inner wall of the extrusion groove, fixing the second rotating rod in the second rotating groove and preventing it from rotating due to external influences. The design of the above structure, through the precise locking of the second rotating rod, ensures that it always remains stably in the preset position, eliminating the assembly deviation of the press-fit shaft caused by the offset rotation of the second rotating rod, avoiding installation instability problems such as loosening or tilting of the press-fit shaft, and thus ensuring that the press-fit shaft always has a reliable positioning reference and operational stability during the stator housing insertion operation, providing a solid guarantee for the subsequent precise assembly of the stator and the housing, while reducing rework and equipment debugging time caused by press-fit shaft installation problems.

A first rotating rod 5 is rotatably connected in each of the two first rotating grooves 4. A bolt 6 is fixedly connected to the bottom end of each of the two first rotating rods 5. The two bolts 6 are respectively located in the two threaded grooves 3 and are threadedly connected to the two threaded grooves 3 respectively. The drive assembly is located on the top surface of the mounting plate 1 and is used to drive the two first rotating rods 5 to rotate. Two positioning grooves 7 are formed inside the mounting plate 1 and communicate with the inner cavity of the mounting plate 1. Positioning plates 8 are inserted into each of the two positioning grooves 7, and the bottom ends of the two positioning plates 8 are fixedly connected to the top surface of the press-fit shaft 2.

[0025] In use, the user drives the two first rotating rods 5 to rotate within the two first rotating slots 4 via the drive assembly. This causes the two first rotating rods 5 to rotate the two bolts 6 respectively, allowing the two bolts 6 to be acted upon by the threads of the two threaded grooves 3. The bolts 6 can simultaneously move from the two threaded grooves 3 to the outside to release the fixation of the press-fit shaft 2, or simultaneously be inserted from the outside into the two threaded grooves 3 to fix the press-fit shaft 2 below the mounting plate 1. This ensures that the user can drive the two bolts 6 to rotate simultaneously, facilitating the replacement of the press-fit shaft 2, reducing the time spent installing the press-fit shaft 2, and improving overall efficiency.

[0026] Example 2: This embodiment provides a motor stator housing device, which, in addition to the technical solutions of the above embodiments, also has the following technical features, and the drive component includes: The housing 9 is fixedly connected to the top surface of the mounting plate 1. Two first gear slots 10 are opened inside the housing 9, and the two first gear slots 10 are respectively connected to two first rotating slots 4. A first bevel gear 11 and a second bevel gear 12 are rotatably connected in both first gear slots 10, and the first bevel gear 11 and the second bevel gear 12 mesh with each other. The bottom end of the first bevel gear 11 extends into the first rotating slot 4 and is fixed to the top end of the first rotating rod 5. Two second gear slots 13 are formed inside the housing 9 and are respectively connected to two first gear slots 10. A third bevel gear 14 and a fourth bevel gear 15 are rotatably connected in each of the two second gear slots 13, and the third bevel gear 14 and the fourth bevel gear 15 mesh with each other. A connecting rod 16 is fixedly connected to one end of the third bevel gear 14, and one end of the connecting rod 16 extends into the first gear slot 10 and is fixed to the second bevel gear 12.

A second rotating rod 18 is rotatably connected inside the second rotating groove 17, and one end of the second rotating rod 18 passes through the inner wall of one of the second gear grooves 13 and extends to the outside. The periphery of the second rotating rod 18 is fixedly connected to the two fourth bevel gears 15. The extrusion groove 19 is formed on the inner wall of the second rotating groove 17; A fixing component is located inside the second rotating rod 18 and is used to fix the second rotating rod 18.

[0027] In operation, the user manually rotates the second rotating rod 18, causing it to drive two fourth bevel gears 15 to rotate within the two second gear slots 13. These four bevel gears 15 then drive two third bevel gears 14, which in turn drive two second bevel gears 12 via two connecting rods 16, rotating them within the two first gear slots 10. As the two second bevel gears 12 rotate, they drive two first bevel gears 11 within the two first gear slots 10. When the two first bevel gears 11 rotate, they drive two first rotating rods 5 within the two first rotating slots 4, ensuring the user can control the simultaneous rotation of the two first rotating rods 5.

[0028] Example 3: This embodiment provides a motor stator housing device, which, in addition to the technical solutions of the above embodiments, also has the following technical features, including a fixing component: A chute 20 is formed inside the second rotating rod 18 and communicates with the extrusion groove 19. A third rotating groove 23 communicating with the outside is formed on the inner wall of the chute 20. An extrusion block 21 is slidably connected inside the chute 20 and is located inside the extrusion groove 19 and in contact with the inner wall of the extrusion groove 19. A threaded rod 22 is threadedly connected inside the extrusion block 21. One end of the threaded rod 22 is fixedly connected to a third rotating rod 24, and one end of the third rotating rod 24 passes through the third rotating groove 23 and extends to the outside to be rotatably connected to the second rotating rod 18.

[0029] In use, the user manually rotates the third rotating rod 24, causing the threaded rod 22 to rotate within the slide groove 20. This causes the pressing block 21 to move along the pressing groove 19 under the action of the threaded rod 22, pressing the pressing block 21 tightly against the inner wall of the pressing groove 19. This fixes the second rotating rod 18 within the second rotating groove 17, preventing it from rotating. This ensures that the second rotating rod 18 can always remain in the preset position and cannot rotate, further increasing the stability of the press shaft 2 installation.

[0030] Example 4: This embodiment provides a motor stator housing device, which, in addition to the technical solutions of the above embodiments, also has the following technical features: the threaded rod 22 is located in the slide groove 20 and is rotatably connected to the inner wall of the slide groove 20; the extrusion block 21 is located in the extrusion groove 19 and is slidably connected to the extrusion groove 19; the third rotating rod 24 is located in the third rotating groove 23 and is rotatably connected to the third rotating groove 23; and the other end of the third rotating rod 24 is rotatably connected to the slide groove 20.

[0031] Specifically, it is ensured that when the threaded rod 22 rotates, the threaded rod 22 can rotate normally within the slide groove 20, and that when the extrusion block 21 slides, the extrusion block 21 can slide normally within the extrusion groove 19. At the same time, it is ensured that when the third rotating rod 24 rotates, the third rotating rod 24 can rotate normally within the third rotating groove 23, and that when the third rotating rod 24 rotates, the other end of the third rotating rod 24 can rotate normally within the slide groove 20.

[0032] Example 5: This embodiment provides a motor stator housing device, which, in addition to the technical solutions of the above embodiments, also has the following technical features: one end of the first bevel gear 11 is rotatably connected to the first rotating groove 4, one end of the connecting rod 16 is rotatably connected to the first gear groove 10, the second rotating rod 18 is rotatably connected to the two second gear grooves 13, and the second rotating rod 18 is rotatably connected to the housing 9.

[0033] Specifically, it is ensured that when the first bevel gear 11 rotates, one end of the first bevel gear 11 can rotate normally within the first rotating groove 4, and that when the connecting rod 16 rotates, one end of the connecting rod 16 can rotate normally within the first gear groove 10. At the same time, it is ensured that when the second rotating rod 18 rotates, the second rotating rod 18 can rotate normally within the two second gear grooves 13, and that when the user rotates the second rotating rod 18, the second rotating rod 18 can rotate normally within the housing 9.

[0034] Working principle: In use, the user manually rotates the second rotating rod 18, causing it to drive the two fourth bevel gears 15 to rotate within the two second gear slots 13. This, in turn, causes the two fourth bevel gears 15 to drive the two third bevel gears 14, which in turn drive the two third bevel gears 14 via the two connecting rods 16, causing the two second bevel gears 12 to rotate within the two first gear slots 10. When the two second bevel gears 12 rotate, they in turn drive the two first bevel gears 11 to rotate within the two first gear slots 10. When the two first bevel gears 11 rotate, the two... The first bevel gear 11 will drive the two first rotating rods 5 to rotate in the two first rotating grooves 4 respectively, so that the two first rotating rods 5 will drive the two bolts 6 to rotate respectively, so that the two bolts 6 can be subjected to the threads of the two threaded grooves 3 respectively, and move from the two threaded grooves 3 to the outside to release the fixation of the press-fit shaft 2, or simultaneously insert from the outside into the two threaded grooves 3 to fix the press-fit shaft 2 under the mounting plate 1. This ensures that the user can drive the two bolts 6 to rotate at the same time, which is convenient for the user to replace the press-fit shaft 2, reduces the time spent installing the press-fit shaft 2, and improves the overall efficiency. When in use, the user inserts the two positioning plates 8 into the two positioning slots 7 by hand, so that the bottom ends of the two bolts 6 can be aligned with the two threaded slots 3 respectively, which facilitates the installation of the press-fit shaft 2; During use, the user manually rotates the third rotating rod 24, causing the threaded rod 22 to rotate within the slide groove 20. This causes the pressing block 21 to move along the pressing groove 19 due to the action of the threaded rod 22, thus pressing the pressing block 21 tightly against the inner wall of the pressing groove 19. This fixes the second rotating rod 18 within the second rotating groove 17, preventing it from rotating. This ensures that the second rotating rod 18 can always remain in the preset position and cannot rotate, further increasing the stability of the press shaft 2 installation.
