Description

Technical Field

[0001] The utility model relates to the technical field of air-floating fan rotor installation, in particular to a portable positioning tool for air-floating fan rotor installation. Background Art

[0002] At present, air-floating fans are used as a new generation of air supply and pressure fans in sewage treatment, aquaculture, papermaking and other industries. They have advantages that traditional fans do not have, such as energy saving, stability and low noise. However, due to the special structure of air-floating centrifugal fans such as air bearings, the rotor of air-floating centrifugal fans may attract the stator during the installation of the rotor during production and assembly. This problem may cause scratches and bumps on the rotor sleeve and stator silicon steel at the least, or even cause the internal magnetic steel of the rotor to break due to impact, the stator to scratch the rotor during operation, and the air bearing to deform. Therefore, special attention is paid to the installation and positioning of the rotor during the assembly process.

[0003] The existing rotor installation plan is to make a large slide or modify a scrapped machine tool. First, fix and install the motor housing of the stator, then use a pin to pass through the stator to lift the rotor, and install it parallel to the stator to prevent the rotor and stator from being sucked together. Finally, install air bearings and end covers on both sides to fix the rotor. After fixing it, release the pin and the installation is completed. However, most of the existing technical solutions are huge equipment, which cannot be miniaturized, occupy a large space, have high manufacturing costs, and have a long production period, and are not convenient to carry out. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a portable positioning tool for installing an air-floating fan rotor, which solves the problems that the tool cannot be miniaturized, occupies a large space, has a high manufacturing cost, and is inconvenient to carry out.

[0005] To achieve the above objectives, the utility model is implemented through the following technical solutions: a portable positioning tool for installing an air-floating fan rotor, comprising a flange fixing plate, a short nylon tube and a long nylon tube, a fan end cover is arranged on the side of the flange fixing plate, a bearing is installed inside the fan end cover, a rotor body is detachably installed on the outside of the bearing, a stator body is arranged on the outside of the rotor body, a short nylon tube is detachably installed on the outside of the rotor body, a long nylon tube is detachably installed on the outside of the rotor body, and the short nylon tube and the long nylon tube are conical structures.

[0006] Preferably, the surface of the flange fixing plate is provided with evenly distributed mounting holes, and the outer surface of the fan end cover is provided with positioning holes corresponding to the mounting holes.

[0007] Preferably, a raised sleeve is arranged on the outside of the flange fixing plate, a through hole is opened on the inner surface of the raised sleeve, and a first positioning groove is arranged on the outer side of the through hole.

[0008] Furthermore, a second positioning groove is formed at one end of the short nylon tube, and the rotor body is arranged inside the first positioning groove and the second positioning groove.

[0009] Furthermore, a first rotor positioning groove is formed inside the second positioning groove, and the first rotor positioning groove extends to the other end of the short nylon tube.

[0010] Furthermore, a second rotor positioning groove corresponding to the first rotor positioning groove is formed at the end of the long nylon tube.

[0011] Beneficial Effects

[0012] The utility model provides a portable positioning tool for installing a rotor of an air-floating fan. Compared with the prior art, it has the following beneficial effects:

[0013] The portable positioning tool for installing the rotor of the air-floating fan is provided with a flange fixing plate, a short nylon tube and a long nylon tube. The flange fixing plate is responsible for fixing the rotor tie rod on the end cover to prevent the rotor and the end cover from displacement. The short nylon tube is responsible for protecting the rotor from contacting the stator and sliding lubrication. The long nylon tube is responsible for guiding the installation of the bearing seat and the end cover on the other side. Through the protection of the long nylon tube, the protected rotor can be directly brought into contact with the stator for insertion installation. After the long nylon tube is installed in place, the end cover can be gently lifted to carry out the end cover and the stator. After assembling the motor casing, tighten the assembly bolts, pull out the long nylon tube, replace it with the short nylon tube, and assemble the end cover on the other side. Since the nylon tube is tapered, it can be directly inserted and installed, thereby cleverly utilizing the assembly holes on the motor casing. It can be removed after assembly without any impact on the product itself. The nylon material has low cost, not only can it maintain lubrication, but also can indirectly contact the rotor and stator, which can meet the assembly requirements and avoid the disadvantage that the air bearing cannot bear too heavy. The overall structure is compact and easy to disassemble and carry, which is more suitable for the current air floating fans. BRIEF DESCRIPTION OF THE DRAWINGS
