Description

Technical Field

[0001] This utility model relates to an assembly device for a fan magnetic ring rotor. Background Technology

[0002] Cooling fans are widely used in various equipment to ensure that the equipment operates within a suitable temperature range; therefore, the heat dissipation performance of cooling fans is crucial for equipment operation. Fans are typically designed with an impeller and motor combined, usually featuring an internal rotor or external rotor structure. In an external rotor structure, the rotor is fixed to the impeller, and the impeller rotates due to the action of the stator and rotor. One type of external rotor fan uses a sleeved magnetic ring installed inside the impeller hub as the rotor. The assembly of the magnetic ring and impeller is usually done manually. Workers place the impeller on a pressing table and use pressure blocks to press the magnetic ring into the hub. This pressing process requires manual fixation of the impeller, resulting in low assembly efficiency and safety hazards. Utility Model Content

[0003] To address the shortcomings mentioned above, this utility model provides an assembly device for a fan magnetic ring rotor.

[0004] To achieve the above objectives, this utility model provides an assembly device for a fan magnetic ring rotor, including a conveying turntable. The conveying turntable has positioning seats evenly arranged along the circumferential direction near its edge for placing the impeller. The upper part of the positioning seats has an integral side limiting block evenly arranged along the circumferential direction to limit the outer wall of the impeller hub. The conveying turntable has a feeding station, a pressing station, and a discharging station arranged sequentially along the clockwise rotation direction. A magnetic ring pressing mechanism is provided above the pressing station, and a magnetic ring feeding mechanism is provided outside the pressing station.

A side push block is provided at the lower opening of the material tube. A groove is machined on the upper left part of the side push block, and the lowest magnetic ring is fitted into the groove. A pair of limiting rods are provided on the side of the side push block facing the conveyor turntable, extending to the top of the positioning seat. A side push cylinder is connected to the side of the side push block away from the conveyor turntable.

[0007] As a further improvement of this utility model, the lower part of the pressing block is provided with a guide head that extends into the inner hole of the magnetic ring, and the pressing cylinder is mounted on a fixed base.

[0008] As a further improvement of this utility model, the outer diameter of the pressing block matches the outer diameter of the magnetic ring, and the distance between the limiting rods is greater than the outer diameter of the magnetic ring and less than the outer diameter of the hub.

[0009] As a further improvement of this utility model, the depth of the groove matches the height of the magnetic ring, an opening is formed on the side of the groove near the conveying turntable, and an arc groove is machined on the side of the groove away from the conveying turntable to match the shape of the magnetic ring.

[0010] As a further improvement of this utility model, the side push block is slidably placed on the base, and the side push cylinder is fixedly connected to the base.

[0011] As a further improvement of this utility model, the side limiting block is offset from the blade on the outer wall of the hub, and an arc-shaped groove is machined at the junction of the side limiting block and the outer wall of the hub.

[0012] As a further improvement of this utility model, the center of the conveyor turntable is fixed on the cam divider.

[0026] like Figure 1 As shown, the assembly device for a fan magnetic ring rotor of this utility model includes a conveyor turntable 2. The center of the conveyor turntable 2 is fixed on a cam divider 1. Positioning seats 3 are evenly provided along the circumferential direction near the edge of the conveyor turntable 2 for placing impellers 4. An integral side limiting block 31 is evenly provided along the circumferential direction on the upper part of the positioning seat 3 to limit the outer wall of the hub 41 in the middle of the impeller 4. The side limiting block 31 is offset from the blades 43 on the outer wall of the hub 41. An arc groove 32 is machined at the junction of the side limiting block 31 and the outer wall of the hub 41. The conveyor turntable 2 is provided with a feeding station 21, a pressing station 22, and a discharging station 23 in sequence along the clockwise rotation direction (see...). Figure 2 A magnetic ring pressing mechanism is provided above the pressing station 22, and a magnetic ring feeding mechanism is provided on the outside of the pressing station 22.

[0027] The magnetic ring pressing mechanism includes a pressing block 5, a pressing cylinder 7 connected to the upper part of the pressing block 5, the pressing block 5 is made of magnetic metal, and a guide head 51 is provided at the lower part of the pressing block 5 to fit into the inner hole of the magnetic ring 9. The pressing cylinder 7 is mounted on the fixed base 6, and the outer diameter of the pressing block 5 matches the outer diameter of the magnetic ring 9.

[0028] The magnetic ring feeding mechanism includes a vertically arranged material tube 8, with magnetic rings 9 stacked inside the material tube 8. The material tube 8 is fixed by a bracket 81. A side push block 10 is provided at the lower opening of the material tube 8. A groove 101 is machined on the upper left side of the side push block 10. The lowest magnetic ring 9 is fitted into the groove 101. The depth of the groove 101 matches the height of the magnetic ring 9. An opening is formed on the side of the groove 101 closest to the conveying turntable 2. An arc groove 102 is machined on the side of the groove 101 furthest from the conveying turntable 2 to match the shape of the magnetic ring 9 (see [reference]). Figure 3The side push block 10 has a pair of limiting rods 103 extending above the positioning seat 3 on the side facing the conveying turntable 2. The distance between the limiting rods 103 is greater than the outer diameter of the magnetic ring 9 and less than the outer diameter of the hub 41. The side push block 10 is connected to the side push cylinder 11 on the side away from the conveying turntable 2. The side push block 10 is slidably placed on the base 12, and the side push cylinder 11 is fixedly connected to the base 12.

[0029] The device automatically feeds the magnetic rings through the cooperation of the material pipe and the side push block. The pressing block attracts the magnetic rings and then presses them into the impeller hub. A limit rod is provided to help the pressing block and the magnetic rings disengage. The mechanical structure replaces manual operation and automatically completes the feeding and pressing process of the magnetic rings, improving assembly efficiency and eliminating safety hazards.

[0030] In practical use, for ease of understanding of this utility model, it will be described in conjunction with the accompanying drawings;

[0031] like Figure 6-7 As shown, the impeller 4 structurally includes a cylindrical hub 41, with multiple blades 43 evenly distributed and fixed on the outer wall of the hub 41. The hub 41 is open at the top and closed at the bottom. Reinforcing ribs 42 are provided on the bottom wall and inner side wall of the hub 41, and are evenly distributed along the circumference of the hub 41, with each reinforcing rib having an L-shaped structure. Figure 8-9 As shown, a sleeve 91 is provided on the outside of the magnetic ring 9. The magnetic ring 9 and the sleeve 91 are fitted with an interference fit. One end of the sleeve 91 is radially bent to form a flange 911. The solution in this embodiment is mainly used to press the magnetic ring with the sleeve into the inner side of the impeller hub in the middle. The reinforcing rib abuts against the outer wall of the sleeve to form an interference fit. The end of the magnetic ring with the flange is set towards the inner bottom surface of the hub. Before assembly, the sleeve has been fitted on the outside of the magnetic ring.

[0032] During operation, each rotation of the conveyor turntable moves one station. At the feeding station, the impeller is placed on the positioning seat manually or by a robot, with the hub opening facing upwards. The side limiting block on the positioning seat limits the outer wall of the hub. The impeller rotates with the conveyor turntable to the pressing station, where multiple magnetic rings are sequentially attracted and arranged inside the material tube, with the flanged end of the outer sleeve of the magnetic ring facing downwards. The bottom magnetic ring falls out of the material tube and is placed in the groove of the side push block. The side push cylinder drives the side push block to move downwards towards the pressing block, creating a radial thrust on the magnetic ring. This forces the magnetic ring to disengage from the magnetic ring above it and move synchronously with the side push block until the magnetic ring reaches the bottom of the pressing block. Then, the pressing cylinder drives the pressing block downwards, and the guide head at the bottom of the pressing block... The pressure block, made of magnetic metal, adheres to the magnetic ring through the inner hole of the magnetic ring. The side push block, driven by a side push cylinder, resets. A limiting rod extends from the side of the side push block to the upper edge of the impeller hub on the positioning seat (there is a gap between the limiting rod and the hub; they do not need to be perfectly matched). The pressure block then moves downwards, causing the magnetic ring to pass between the two limiting rods and press into the reinforcing ribs inside the hub, forming an interference fit. The pressure cylinder then drives the pressure block upwards to reset. An adsorption force remains between the pressure block and the magnetic ring. The limiting rod restricts the overall upward movement of the impeller, separating the pressure block from the magnetic ring. After assembly, the impeller rotates with the conveyor turntable to the discharge station, where it can be removed manually or by a robotic arm.

[0033] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
