Description

Technical Field

[0001] This utility model relates to the technical field of motor installation equipment, specifically a rear-mounted disc-type permanent magnet motor mounting base. Background Technology

[0002] The rear-mounted disc permanent magnet motor is a type of motor that adopts a flat disc-shaped design and has a magnetic field distributed along the axis. Its rotor and stator are arranged in parallel discs to form a unique axial air gap magnetic field structure.

[0003] Existing rear-mounted disc permanent magnet motor mounting bases are usually installed using bolts. During installation, it is necessary to strictly follow the position of the bolt posts on the base when drilling holes in the motor body. When it is necessary to replace with a different model of permanent magnet motor, the original hole positions are no longer applicable due to the change in the position of the bolt posts, and it is necessary to re-drill holes in the motor body. This process is cumbersome and can damage the motor body, thus having limitations.

[0004] The reason for this problem is that most existing rear-mounted disc permanent magnet motor mounting bases are designed for specific motor models. Before bolt installation, holes need to be drilled in the motor body according to the bolt post positions to ensure proper installation. This increases the complexity and time cost of installation. When a different permanent magnet motor needs to be replaced, the bolt post positions change, requiring re-drilling in the motor body. This process is not only cumbersome but also causes some damage to the motor body, reducing its service life. Furthermore, frequent drilling operations can reduce the structural strength of the motor body, affecting the installation stability and operational safety of the motor. Therefore, we propose a rear-mounted disc permanent magnet motor mounting base to solve the above problems. Utility Model Content

The nut 23 is used to fix the fixed column 21 after it is inserted into the inside of the slider 22.

[0028] The upper base 11 has a sliding groove 24 inside, which is arranged in a ring array. Anti-detachment blocks 25 are fixedly connected to both sides of the slider 22. The anti-detachment blocks 25 are slidably connected inside the sliding groove 24. The slider 22 is threadedly connected to a fastening bolt 26, which abuts against the bottom of the rear disc permanent magnet motor. A protrusion 27 is fixedly mounted at the end of the upper base 11, and a threaded post 28 is fixedly mounted at the end of the protrusion 27.

[0029] In this embodiment, based on the position of the motor fixing post 21, the slider 22 inside the upper base 11 is slid so that the slider 22 corresponds to the position of the fixing post 21. Then, the fixing post 21 at the bottom of the motor is inserted into the interior of the slider 22. By rotating the nut 23, it is threadedly engaged with the fixing post 21 and abuts against the slider 22, thereby initially fixing the motor on the upper base 11. Next, the fastening bolt 26 inside the slider 22 is rotated so that its end abuts against the bottom of the motor, further fixing the motor and ensuring the installation accuracy of the motor. The protrusion 27 at the end of the upper base 11 is aligned with the guide groove 29 inside the lower base 12, and the protrusion 27 is inserted into the guide groove 29. At this time, the threaded post 28 is threadedly engaged with the lower base 12. By rotating the threaded post 28, the upper base 11 and the lower base 12 are spliced ​​together. The mounting base 1 is connected and fixed to the machine body through the fixing block 214 and fixing bolt 215 on the outer surface of the lower base 12. The machine body is the component that needs to install the permanent magnet motor; "machine body" is just a formal name.

[0030] Example 2

[0031] This utility model embodiment discloses a rear-mounted disc permanent magnet motor mounting base. More specifically, based on Embodiment 1, it is provided with... Figure 1 , 3 As shown, it includes a mounting base 1, which is composed of an upper base 11 and a lower base 12. The mounting base 1 is equipped with a disassembly and assembly unit 2 for disassembling and assembling a rear-mounted disc permanent magnet motor. The disassembly and assembly unit 2 includes a fixing column 21, a slider 22 and a nut 23.

[0032] The fixed column 21 is fixedly assembled at the bottom of the rear-mounted disc permanent magnet motor, and the fixed column 21 is distributed in a ring array; the slider 22 is slidably connected to the inside of the upper base 11, and the fixed column 21 is movably inserted into the inside of the slider 22; the nut 23 is sleeved on the outer surface of the fixed column 21, the nut 23 is threadedly engaged with the fixed column 21, and the nut 23 abuts against the slider 22. The nut 23 is used to fix the fixed column 21 after it is inserted into the inside of the slider 22.

[0033] The lower base 12 has a guide groove 29 inside, and the protrusion 27 is movably engaged inside the guide groove 29. The threaded post 28 is threadedly engaged with the lower base 12. The lower base 12 has a fixing hole 210 inside, which is arranged in a ring array. A plug rod 211 is movably inserted into the fixing hole 210. A magnetic suction piece 212 is fixedly mounted at the bottom of the plug rod 211 and is magnetically connected to the lower base 12. An anti-slip piece 213 is fixedly mounted at the top of the plug rod 211 and the end of the anti-slip piece 213 abuts against the end of the protrusion 27. A fixing block 214 is fixedly connected to the outer surface of the lower base 12. The fixing blocks 214 are arranged in a ring array and a fixing bolt 215 is threadedly engaged inside the fixing block 214.

[0034] In this embodiment, the insertion rod 211 is inserted into the fixing hole 210 of the lower base 12. Since the magnetic piece 212 at the bottom of the insertion rod 211 is magnetically connected to the lower base 12, the insertion rod 211 is fixed on the lower base 12. At the same time, the end of the anti-slip piece 213 at the top of the insertion rod 211 abuts against the end of the protrusion 27, further enhancing the stability of the splicing of the upper base 11 and the lower base 12. The function of the anti-slip piece 213 is to prevent the threaded post 28 from gradually loosening due to motor vibration. The anti-slip piece 213 is in contact with the protrusion 27, and the friction force cancels out the force generated by the vibration, preventing the threaded post 28 from gradually loosening and meeting the user's needs.
