Description

Technical Field

[0001] The utility model relates to the technical field of magnetic suspension blower maintenance, in particular to an auxiliary tool for disassembling a main engine impeller of a magnetic suspension blower. Background Art

[0002] Blowers are an important piece of equipment used in various fields of industrial production. They can increase air pressure or provide airflow, playing a key role in ventilation, air conditioning, heating, cooling, and conveying materials.

[0003] Among them, the magnetic levitation fan is a type of centrifugal fan. Its three-dimensional flow impeller is assembled using an advanced locking connection method, which allows the impeller to be directly connected to the shaft. This connection method not only ensures efficient transmission, but also provides a strong guarantee for the stable operation of the fan.

[0004] like Figure 1 As shown, in the existing magnetic levitation blower, the impeller is fixed to the motor shaft through the impeller shaft, and a speed sensor is fixedly sleeved on the outer wall of the motor shaft at one end away from the impeller. A plurality of protrusions are arranged in a ring on the outer peripheral surface of the speed sensor, and the spacing between the plurality of protrusions is equal.

[0005] After a long period of operation, the magnetic levitation blower sometimes needs maintenance due to various reasons. At this time, the impeller of the magnetic levitation blower needs to be disassembled first. At present, the method of disassembling the impeller of the magnetic levitation blower is mainly to press the impeller with both hands so that the impeller will not rotate with the motor shaft, and then unscrew the locking nut. However, the edges and corners of the impeller are sharp and it is easy to scratch your hands, which poses a major safety hazard. Utility Model Content

[0006] The main technical problem to be solved by the utility model is to provide an auxiliary tool for disassembling the main impeller of a magnetic levitation blower with a simple structure and easy operation. The motor shaft is fixed by the tool, so that the impeller will not rotate with the shaft when the impeller is disassembled, and there is no need to fix the impeller by hand, thus avoiding scratches and reducing safety hazards.

[0007] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0008] An auxiliary tool for disassembling the impeller of a main engine of a magnetic levitation blower includes a disassembly barrel body, which is a hollow cylinder with openings at both ends. A handle is fixedly connected to the outer circumferential surface of the disassembly barrel body and near one of the end positions of the disassembly barrel body, and the axial direction of the handle is perpendicular to the axial direction of the disassembly barrel body. A plurality of slots are provided at the other end of the disassembly barrel body, and the slots match the protrusions on the outer circumferential surface of the speed sensor rotor fixedly sleeved on the motor shaft. The slots are used to clamp the protrusions on the outer circumferential surface of the speed sensor rotor when the speed sensor is placed in the disassembly barrel body. The slots of the disassembly barrel body can accommodate the protrusions on the outer circumferential surface of the speed sensor rotor to be clamped in the axial direction of the disassembly barrel body.

[0009] The following is a further optimization of the above technical solution by the present invention:

[0010] The projection of the card slot is a rectangle.

[0011] Further optimization: the clamping grooves all penetrate the disassembly cylinder body along the diameter direction of the disassembly cylinder.

[0012] Further optimization: the height of the slot is smaller than the height of the protrusion on the outer peripheral surface of the speed sensor rotor.

[0013] Further optimization: the width of the slot is 2mm-3mm smaller than the width of the protrusion on the outer peripheral surface of the speed sensor rotor.

[0014] Further optimization: the arc length of the slot is 1mm-3mm greater than the arc length of the protrusion on the outer peripheral surface of the speed sensor rotor.

[0015] Further optimization: the handle is in the shape of an elongated strip.

[0016] Further optimization: a handle protective cover is provided on the outer side wall of the handle, the handle protective cover is made of elastic material, and anti-slip patterns are evenly provided on the outer side wall of the handle protective cover.

[0017] By adopting the above technical solution, the utility model has a simple structure and is easy to operate. The motor shaft is fixed by the tool, so that the impeller will not rotate with the shaft when the impeller is removed. There is no need to fix the impeller by hand, thus avoiding scratches and reducing safety hazards.

[0025] like Figure 1-5 As shown, an auxiliary tool for disassembling the impeller of the main engine of a magnetic levitation blower includes a disassembly cylinder body 4, and the disassembly cylinder body 4 is a hollow cylinder with openings at both ends. A handle 5 is fixedly connected to the outer circumferential surface of the disassembly cylinder body 4 and near one end position of the disassembly cylinder body 4, and the axial direction of the handle 5 is perpendicular to the axial direction of the disassembly cylinder body 4. A plurality of slots 6 are provided at the other end of the disassembly cylinder body 4, and the slots 6 match the protrusions 3 on the outer circumferential surface of the speed sensor rotor fixedly sleeved on the motor shaft 2. The slots 6 are used to clamp the protrusions 3 on the outer circumferential surface of the speed sensor rotor when the speed sensor is placed in the disassembly cylinder body 4. The slots 6 of the disassembly cylinder body 4 can accommodate the protrusions 3 on the outer circumferential surface of the speed sensor rotor to be clamped in the axial direction of the disassembly cylinder body 4.

[0026] First, hold the disassembly barrel body 4 and align its end with the slot 6 with the speed sensor on the motor shaft 2. Since the disassembly barrel body 4 is a hollow cylinder with two ends open, it can be easily put on the outer periphery of the speed sensor.

[0027] Then, slowly push the disassembly cylinder body 4 toward the speed sensor so that the protrusion 3 on the outer peripheral surface of the speed sensor rotor is aligned with the slot 6 at the end of the disassembly cylinder body 4. As the push continues, the protrusion 3 is inserted into the slot 6 along the axial direction of the disassembly cylinder body 4 until it is completely inserted. At this time, the disassembly cylinder body 4 is tightly connected to the speed sensor. Because the slot 6 matches the protrusion 3, the disassembly cylinder body 4 and the speed sensor form a whole and can rotate synchronously.

[0028] When the disassembly tool is installed, the operator holds the handle 5. When the impeller 1 is disassembled, the motor shaft 2 tends to rotate. The operator applies a resistance in the opposite direction of the rotation of the motor shaft 2 to the handle 5, effectively preventing the motor shaft 2 from rotating. Therefore, during the entire impeller 1 disassembly process, the motor shaft 2 can be kept stationary at all times, and the impeller 1 can be smoothly disassembled from the motor shaft 2. At the same time, various problems that may be caused by the rotation of the motor shaft 2 are avoided, such as damage to the connection between the motor shaft 2 and the impeller 1 and affecting the normal position of other surrounding components.

[0029] With this design, first, the disassembly cylinder body 4 adopts a hollow cylindrical design with openings at both ends, so that it can be easily aligned and put on the outer periphery of the speed sensor during the initial operation, which greatly reduces the difficulty and complexity of the operation; at the same time, the matching design of the speed sensor protrusion 3 and the card slot 6 of the disassembly cylinder body 4 only requires slow pushing to achieve precise docking, without the need for a complicated adjustment process, making the installation and disassembly tools simple and quick, greatly improving work efficiency.

[0030] Secondly, when the protrusion 3 is fully inserted into the slot 6, the disassembly cylinder body 4 is tightly connected to the speed sensor to form a stable whole. This connection method ensures that the force can be effectively transmitted during the disassembly of the impeller 1, and there will be no loosening or slipping, providing reliable guarantee for the smooth disassembly of the impeller 1.

[0031] Again, the design of the handle 5 having an axial direction perpendicular to the axial direction of the disassembly cylinder body 4 conforms to ergonomic principles and provides the operator with a comfortable gripping position and force application angle, so that during the disassembly process, the operator can more easily hold the handle 5 and apply force, reducing hand fatigue and the possibility of operational errors.

[0032] Finally, during the disassembly of the impeller 1, the motor shaft 2 may tend to rotate due to various reasons. The staff can effectively prevent the motor shaft 2 from rotating by applying resistance in the opposite direction of the rotation of the motor shaft 2 to the handle 5, thereby ensuring the stability and controllability of the disassembly process and avoiding problems such as difficulty in disassembling the impeller 1 and damage to components due to the rotation of the motor shaft 2.

[0033] The projection of the card slot 6 is a rectangle.

[0034] With this design, first, the rectangular slot 6 is easy to manufacture during machining, so that the dimensional accuracy and surface quality can be precisely controlled, reducing the processing cost and difficulty; and by using standard measuring tools and parameters, the length, width and height of the slot 6 can be precisely controlled to ensure precise fit with the protrusion 3, thereby improving the reliability of the tool.

[0035] Secondly, after the protrusion 3 is inserted, the rectangular slot 6 is in stable contact with the protrusion 3, making it difficult for the protrusion 3 to tilt or shake in the slot 6, and can effectively transmit the force to prevent the motor shaft 2 from rotating, preventing the motor shaft 2 from rotating due to uneven force; at the same time, it has good adaptability to the protrusion 3 of regular shape, can reduce gaps and stress concentration, and enhance connection reliability.

[0036] Again, during installation, the operator can easily determine the relative positions of the protrusion 3 and the slot 6 through the rectangular outline, reducing the difficulty of alignment; at the same time, the straight edge design is conducive to the smooth insertion of the protrusion 3, and during disassembly, the regular shape makes it easy to apply appropriate force to make the protrusion 3 fall out, and it will not be difficult to remove due to the complex shape.

[0037] The clamping grooves 6 all penetrate the disassembly cylinder body 4 along the radial direction of the disassembly cylinder body 4 .

[0038] With this design, first, when the speed sensor is placed into the disassembly cylinder body 4, the design of the slot 6 running through the radial direction of the disassembly cylinder body 4 enables the operator to clearly see the relative positions of the protrusion 3 on the outer peripheral surface of the speed sensor rotor and the slot 6, thereby enabling the operator to more easily align the protrusion 3 with the slot 6, thereby improving the accuracy and efficiency of the installation and reducing errors during the installation process.

[0039] Secondly, during disassembly, the penetrating slot 6 will not hinder the removal of the protrusion 3, which greatly improves the convenience of disassembly.

[0040] The height of the slot 6 (i.e. Figure 3 (shown in a) is smaller than the height of the protrusion 3 on the outer circumferential surface of the speed sensor rotor.

[0041] With this design, firstly, the operator can easily observe the relative position of the protrusion 3 and the slot 6, thereby facilitating the operator to quickly and accurately align the protrusion 3 with the slot 6, thereby reducing the difficulty of installation.

[0042] Secondly, because the height of the slot 6 is smaller than the height of the protrusion 3, there is no need for precise matching in the height direction. As long as the protrusion 3 falls into the slot 6, the basic installation can be completed. This greatly reduces the requirements for installation accuracy in the height direction, making the installation process easier and more efficient.

[0043] Again, the height of the slot 6 is smaller than the height of the protrusion 3 on the outer peripheral surface of the speed sensor rotor, which limits the disassembly cylinder body 4 from being too close to other components in the magnetic levitation blower during installation, and maintains a certain safety gap. Therefore, in the process of installing and matching the speed sensor with the disassembly cylinder, inside the magnetic levitation blower, the disassembly cylinder body 4 will not collide or interfere with other components in the magnetic levitation blower.

[0044] The width of the card slot 6 (i.e. Figure 3(shown in b) is 2mm-3mm smaller than the width of the protrusion 3 on the outer peripheral surface of the speed sensor rotor.

[0045] With this design, the width of the slot 6 is 2mm-3mm smaller than the width of the protrusion 3 on the outer peripheral surface of the speed sensor rotor, which limits the disassembly cylinder body 4 from being too close to other components in the magnetic levitation blower during installation, and maintains a certain safety gap. Therefore, in the process of installing and matching the speed sensor with the disassembly cylinder body 4, inside the magnetic levitation blower, the disassembly cylinder body 4 will not collide or interfere with other components in the magnetic levitation blower.

[0046] The arc length of the slot 6 is 1 mm to 3 mm greater than the arc length of the protrusion 3 on the outer peripheral surface of the speed sensor rotor.

[0047] With this design, first, the arc length of the slot 6 is 1mm-3mm longer than the arc length of the protrusion 3 on the outer peripheral surface of the speed sensor rotor, which significantly reduces the difficulty of installation. The operator does not need to perform high-precision alignment. Even if there is an angle or position deviation, the protrusion 3 can smoothly enter the slot 6, greatly improving work efficiency. At the same time, the appropriate arc length margin reduces the friction resistance during insertion, making the insertion process smoother, which is particularly suitable for frequent impeller 1 disassembly operations, saving physical strength and time.

[0048] Secondly, during the disassembly of the impeller 1, the equipment may vibrate or move. The long arc length of the slot 6 provides a buffer space for the protrusion 3, allowing it to move freely in the slot 6, and acts like a buffer pad to prevent the protrusion 3 from colliding with the edge of the slot 6, thereby ensuring the stability of the connection between the disassembly cylinder body 4 and the speed sensor; moreover, compared with the case of similar arc length, this design can prevent the protrusion 3 from being damaged due to friction, collision or even jamming, thereby extending the service life of the equipment components.

[0049] During disassembly, the speed sensor is forced through the slot 6 to prevent the motor shaft 2 from rotating. The long arc length of the inner wall of the slot 6 in contact with the side of the protrusion 3 can evenly distribute the clamping force, ensuring that the force is effectively transmitted to the protrusion 3, thereby ensuring that the disassembly work proceeds smoothly. In addition, it also avoids the stress concentration problem that may be caused by the same arc length of the slot 6 and the protrusion 3, making the force transmission more stable and reducing the risk of component damage.

[0050] The handle 5 is in the shape of an elongated strip.

[0051] This design, first of all, provides sufficient length to apply torque, making it convenient to operate with the help of hands or body strength, which is more labor-saving and efficient.

[0052] Secondly, the large grip area provides a stable grip, preventing your hands from slipping, ensuring operational accuracy and reducing errors.

[0053] Again, it can adapt to different hand sizes and operating habits, improving the versatility of the tool.

[0054] The outer wall of the handle 5 is covered with a handle protective cover 7, which is made of elastic material. The outer wall of the protective cover is evenly provided with anti-slip patterns.

[0055] With this design, firstly, the protective cover serves as the outer protection of the handle 5, which can prevent the surface of the handle 5 from being scratched, worn or subjected to other physical damages, thereby extending the service life of the handle 5, and during operation, the protective cover can prevent wear and tear on the skin of the hand.

[0056] Secondly, the friction between the hand and the handle 5 is increased, thereby improving the stability of the operation.

[0057] In this embodiment, the handle protective cover 7 is made of rubber material.

[0058] For ordinary technicians in this field, based on the teachings of this utility model, without departing from the principles and spirit of this utility model, changes, modifications, substitutions and variations made to the implementation methods are still within the scope of protection of this utility model.
