Description

Technical Field

[0001] This utility model discloses a stator quick positioning and installation fixture, belonging to the field of assembly tool technology, specifically relating to a stator assembly tool. Background Technology

[0002] A centrifugal fan is a mechanical device used for conveying, pressurizing, and exhausting air. It uses a motor to drive an impeller to rotate at high speed, utilizing centrifugal force to draw air or gas in from the center and expel it to the surrounding area, generating pressure or suction. A centrifugal fan mainly consists of a motor, impeller, bearings, gearbox, casing, inlet and outlet pipes, and stator. Among these components, the stator and rotor are the two most important, working together to achieve the centrifugal fan's rotation and airflow boosting functions.

[0003] The stator is the stationary part inside the casing, typically using guide vanes or straight blades to guide the air in and out. The rotor, on the other hand, is the dynamic component of the centrifugal fan. It usually consists of many blades and rotates via the main shaft, accelerating and expelling air from the centrifugal fan. Traditionally, fan stators are assembled manually during production, but this method has the following problems:

[0004] 1. Assembly accuracy issues: Manual assembly may lead to inaccurate positioning, affecting the coaxiality between the stator and the housing, thereby affecting the overall performance and lifespan of the motor.

[0005] 2. High labor intensity: Methods such as bolt connection require a lot of manual operation, especially in the assembly of large motors. This not only increases labor costs, but may also lead to poor assembly consistency. Utility Model Content

[0006] Purpose of the utility model: To provide a stator assembly tool to solve the problems mentioned above.

[0007] Technical solution: A stator assembly tool, the assembly tool comprising: an inner rod, an outer rod, a rubber sleeve, and a positioning sleeve;

[0008] The upper part of the inner rod is sleeved inside the outer rod, the positioning sleeve is sleeved on the lower part of the inner rod, and the rubber sleeve is sleeved on the inner rod and located between the contact point of the inner rod and the outer rod.

[0009] As the inner rod moves upward, it causes the rubber sleeve and the bottom of the outer rod to compress.

[0010] In a further embodiment, the outer rod is divided into a limiting frame, a fixing rod body, and a base from top to bottom;

[0011] The fixed rod is connected between the limiting frame and the base, and the fixed rod has a cavity portion that sleeves the inner rod.

[0012] In a further embodiment, the inner rod is divided into a pull ring, an upper rod body, a middle seat, and a lower rod body from top to bottom;

[0013] The upper rod is connected between the pull ring and the intermediate seat, and the lower rod is fixed to the bottom of the intermediate seat; the lower rod has a cavity-like interior.

[0014] The pull ring is located within the limiting frame, and the upper rod is sleeved within the fixed rod body with a clearance fit to move up and down within the fixed rod body.

[0015] In a further embodiment, the positioning sleeve is fitted onto the outside of the lower rod.

[0016] In a further embodiment, the length of the upper rod is greater than the length of the fixed rod, and the rubber sleeve is fitted onto the bottom of the upper rod and located between the intermediate seat and the base.

[0017] Beneficial effects: This utility model utilizes the principle that the larger the contact area, the greater the friction. Inner and outer rods compress the rubber, causing it to deform and increase the contact area with the inner ring of the stator, thus connecting the stator and rods as one unit. The inner rod, in conjunction with the positioning sleeve, accurately positions the stator and motor housing coaxially. The contact surface is at the inner ring of the stator and is a rubber contact, protecting the stator coil and ensuring a certain distance between the stator and assembly personnel to prevent burns from the motor housing. Positioning is convenient, improving assembly accuracy and efficiency. The split design of the inner rod facilitates adaptation to different stator models. Attached Figure Description

[0025] A stator assembly tool includes: an inner rod 1, an outer rod 2, a rubber sleeve 3, and a positioning sleeve 4.

[0026] In one embodiment, such as Figures 1 to 3 As shown, the upper part of the inner rod 1 is sleeved inside the outer rod 2, the positioning sleeve 4 is sleeved on the lower part of the inner rod 1, and the rubber sleeve 3 is sleeved on the inner rod 1 and located between the contact point of the inner rod 1 and the outer rod 2.

[0027] As the inner rod 1 moves upward, it causes the rubber sleeve 3 and the bottom of the outer rod 2 to be compressed.

[0028] In one embodiment, such as Figures 1 to 3 As shown, the outer rod 2 is divided into a limiting frame 10, a fixed rod body 11 and a base 12 from top to bottom;

[0029] The fixed rod 11 is connected between the limiting frame 10 and the base 12, and the fixed rod 11 has a cavity portion for sleeved with the inner rod 1.

[0030] In one embodiment, such as Figures 1 to 3 As shown, the inner rod 1 is divided into a pull ring 20, an upper rod body 21, an intermediate seat 22 and a lower rod body 23 from top to bottom;

[0031] The upper rod 21 is connected between the pull ring 20 and the intermediate seat 22, and the lower rod 23 is fixed to the bottom of the intermediate seat 22; the lower rod 23 has a cavity inside.

[0032] The pull ring 20 is located inside the limiting frame 10, and the upper rod 21 is sleeved inside the fixed rod 11 and uses a clearance fit to move up and down inside the fixed rod 11.

[0033] In one embodiment, such as Figures 1 to 3 As shown, the positioning sleeve 4 is fitted onto the outside of the lower rod body 23.

[0035] Working principle: Utilizing the principle that the larger the contact area, the greater the friction, the inner rod 1 squeezes the rubber sleeve 3 inside the outer rod 2, causing the rubber sleeve 3 to deform and increase the contact area with the inner ring of the stator, thus connecting the stator and the rod as one unit. Then, the inner rod 1 cooperates with the positioning sleeve 4 to accurately position the stator and the motor housing coaxially.

[0036] The contact surface is rubber-coated with the inner ring of the stator, protecting the stator windings. It ensures a safe distance between the stator and assembly personnel to prevent burns from the motor housing. Positioning is convenient, improving assembly accuracy and efficiency. The split design of the inner rod 1 facilitates adaptation to different stator models.
