Description

Technical Field

[0001] This utility model relates to the field of fan processing technology, specifically to an auxiliary device for fan installation. Background Technology

[0002] The core of fan manufacturing is to proceed according to the process of "component manufacturing → assembly → testing → packaging". It is necessary to control the precision and safety standards to ensure the stable operation of the product. The fan blades are mostly made of ABS / PP plastic injection molding, the metal mesh is formed by stamping and welding, and the motor housing is made by die casting or stretching. The core components of the motor need to be precisely wound and assembled. The process is to fix the motor and housing, install the fan blades, assemble the mesh, connect the power cord and control components, and finally tighten the whole assembly. Then, power-on test run, safety test, noise test, and appearance defect inspection are carried out. Defective products are returned for repair. Qualified products are bagged, packed with foam cushioning and outer packaging boxes, labeled and put into the warehouse to await logistics and distribution.

[0003] When installing and processing fans, the fan housing is placed on the workbench, and then the motor, fan blades and other parts are assembled. However, the rear surface of the fan housing is often designed with an arc shape, making it difficult to place stably on the workbench. As a result, the personnel can only hold the housing by hand during installation, which reduces the efficiency of the installation and processing. Utility Model Content

[0004] The purpose of this utility model is to provide an auxiliary device for fan installation, in order to solve the problem mentioned in the background art that the rear surface of the fan housing is often arc-shaped, making it difficult to place stably on the workbench, which forces personnel to hold the housing by hand for installation, thus reducing the efficiency of installation and processing.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an auxiliary device for fan installation, comprising a limiting housing, with two supporting columns fixedly connected to its lower surface. The supporting columns have positioning grooves on their side surfaces, a fixed base is provided on the lower outer surface of the supporting columns, and a positioning block is installed on the upper side surface of the fixed base. A limiting slot is provided on the bottom surface of the groove of the limiting housing, and a buffer slide is provided on the inner wall of the limiting slot. A supporting baffle is fixedly connected to the upper end of the buffer slide. Supporting slides are provided on the inner wall of the cavity of the limiting housing, and a pressing clamp is fixed to one end of each of the two supporting slides. An inflation linkage mechanism is provided on the surface of the limiting housing.

[0006] Preferably, the limiting shell is cylindrical, the positioning groove is directional and arranged vertically on the side surface of the supporting column, the fixed base frame is slidably connected to the supporting column, the fixed base frame is slidably connected to the positioning block, a spring is connected between the fixed base frame and the positioning block, and the positioning block and the positioning groove are engaged.

[0007] Using the above technical solution, the cylindrical limiting housing is compatible with most round fan housings, with a higher fit and to prevent placement deviation. The vertically arranged positioning grooves, together with the positioning blocks, can flexibly adjust the height of the device to meet the installation needs of fans of different sizes. The fixed base and the support column are slidably connected by a spring-loaded locking structure, which makes the adjustment operation simple and provides strong stability after the positioning blocks are engaged, preventing height deviation during use.

[0008] Preferably, the limiting slot is a cylindrical design and the limiting slots are arranged in a circumferential array. The limiting slot and the buffer slide are slidably connected, and a spring is connected between the limiting slot and the buffer slide. The surface of the supporting baffle is provided with a buffer pad.

[0009] Using the above technical solution, the cylindrical limiting slots of the circumferential array make the buffer slide evenly stressed, and more stable when supporting the fan shell. The combination design of the buffer slide and spring can absorb the impact force during placement and avoid bumps and damage to the surface of the fan shell. The buffer pad on the surface of the support baffle further enhances the protection and increases friction to reduce the sliding of the shell.

[0010] Preferably, the supporting slide column and the limiting housing are slidably connected, and a spring is connected between the supporting slide column and the limiting housing. The pressing clamp is arc-shaped, and an anti-slip rubber block is fixedly connected to the surface of the pressing clamp.

[0011] The above technical solution supports the sliding connection structure between the sliding column and the spring, allowing the pressing clamp to have elastic adjustment space to adapt to fan housings of different diameters. The arc-shaped pressing clamp fits the curved surface of the fan housing, with a larger clamping area and a more secure fixation, preventing the housing from shaking during installation. The anti-slip rubber block increases the clamping friction while preventing the clamp from directly contacting the housing and causing scratches, thus balancing stability and protection.

[0012] Preferably, the inflation linkage mechanism includes an air inlet pipe, which is fixedly connected to the lower surface of the limiting housing. The limiting housing has a first air groove inside, and a second air groove is formed at the upper end of the first air groove. A sealing piston head is provided on the inner wall of the second air groove, and a linkage support is fixed at one end of the sealing piston head.

[0013] Using the above technical solution, the inflation linkage mechanism is driven by gas to achieve automatic clamping of the pressing block without manual adjustment, thus improving installation efficiency. The combination of air inlet pipe, air groove and sealed piston head has strong airtightness of transmission structure, rapid gas drive response and precise clamping action. The linkage support is directly connected to the pressing block, and the power transmission is direct, ensuring uniform clamping force and avoiding damage to the shell due to excessive local pressure.

[0014] Preferably, the air intake pipe is connected to the first air groove, and the first air groove is annular, the second air groove is L-shaped, and one end of the second air groove penetrates the inner wall of the limiting housing cavity.

[0015] Using the above technical solution, the annular first air groove evenly distributes the gas to each of the second air grooves, ensuring that multiple pressing clamps move synchronously and are balanced in force during clamping. The L-shaped second air groove optimizes the gas flow path, avoids pipe bends affecting airflow, and adapts to the internal structure layout of the limiting housing, saving space. The design of the second air groove penetrating the inner wall of the cavity ensures that the sealing piston head drives the linkage support with sufficient stroke and a wider clamping range.

[0016] Preferably, the sealing piston head and the second air groove are slidably connected, and one end of the linkage support is fixedly connected to the surface of the pressing clamp block.

[0017] The above technical solution features a sliding connection between the sealed piston head and the second gas groove, ensuring good sealing, high gas utilization, stable clamping power without loss, and a fixed connection between the linkage support and the pressing clamp, resulting in seamless transmission and precise transmission of the piston head's thrust. This ensures accurate clamping position, minimal wear on the sliding connection structure, and a long service life with a spring reset design, leading to low subsequent maintenance costs.

[0018] Compared with the prior art, the beneficial effects of this utility model are: the auxiliary device for fan installation: 1. Combining adaptability and convenience, the device significantly improves installation efficiency. Through the interlocking structure of the vertically arranged positioning grooves and positioning blocks on the support column, the height of the fixed base can be flexibly adjusted. It is compatible with fan housings of different sizes and specifications, eliminating the need for frequent replacement of auxiliary tools, effectively simplifying the operation process, and solving the core problem of the difficulty in placing curved housings stably. 2. Comprehensive protection ensures product processing quality. The cushioning pads on the support baffle surface, combined with the shock-absorbing design of the cushioning slide and spring, can alleviate the impact force when the fan shell is placed, avoiding bumps and damage. The combination of the arc-shaped pressing clamp and the anti-slip rubber block ensures both clamping firmness and prevents scratches on the shell surface, improving the finished product qualification rate. 3. Automated clamping reduces operational difficulty and enhances stability. The pneumatic linkage mechanism drives the sealed piston head and linkage support through gas to automatically clamp the outer shell with the pressing clamp, eliminating the need for manual assistance, reducing labor intensity and avoiding human error. All components cooperate with springs and sliding structures, resulting in rapid transmission response and convenient reset. The overall operation is stable and reliable, improving the consistency of batch processing. Attached Figure Description

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-6 This utility model provides a technical solution: an auxiliary device for fan installation, including a limiting housing 1, supporting columns 2, positioning grooves 3, a fixed base frame 4, positioning blocks 5, limiting slots 6, buffer sliding columns 7, supporting baffles 8, supporting sliding columns 9, pressing clamps 10, anti-slip rubber blocks 11, air intake pipes 12, first air grooves 13, second air grooves 14, sealing piston heads 15, and linkage support columns 16. The limiting housing 1 has two supporting columns 2 fixedly connected to its lower surface. The limiting housing 1 is cylindrical, and the positioning grooves 3 are directional. The positioning grooves 3 are arranged vertically on the side surface of the support column 2. The fixed base frame 4 is slidably connected to the support column 2, and the fixed base frame 4 is slidably connected to the positioning block 5. A spring is connected between the fixed base frame 4 and the positioning block 5, and the positioning block 5 is engaged with the positioning grooves 3. Pulling the fixed base frame 4 along the support column 2 and adjusting it to the appropriate height, the spring between the fixed base frame 4 and the positioning block 5 pushes the positioning block 5 into the positioning grooves 3 on the side surface of the support column 2, thus fixing the height of the device and adapting to different installation scenarios.

[0023] The side surface of the support column 2 is provided with a positioning groove 3. The lower outer surface of the support column 2 is provided with a fixed base frame 4. The upper side surface of the fixed base frame 4 is provided with a positioning insert 5. The limiting slot 6 is a cylindrical design and is arranged in a circular array. The limiting slot 6 and the buffer slide column 7 are slidably connected. A spring is connected between the limiting slot 6 and the buffer slide column 7. The surface of the support baffle 8 is provided with a buffer pad. The support slide column 9 and the limiting housing 1 are slidably connected. A spring is connected between the support slide column 9 and the limiting housing 1. The pressing clamp 10 is an arc-shaped design. The surface of the pressing clamp 10 is fixedly connected with an anti-slip rubber block 11. When the fan shell is placed on the surface of the support baffle 8, the weight of the shell causes the buffer slide column 7 to slide down along the limiting slot 6. The spring between the buffer slide column 7 and the limiting slot 6 is compressed to achieve buffering and shock absorption, avoiding direct collision damage to the shell.

[0024] A limiting slot 6 is formed on the bottom surface of the groove of the limiting housing 1. A buffer slide 7 is provided on the inner wall of the limiting slot 6. A support baffle 8 is fixedly connected to the upper end of the buffer slide 7. A support slide 9 is provided on the inner wall of the cavity of the limiting housing 1. A pressing clamp 10 is fixed to one end of each of the two support slides 9. The inflation linkage mechanism includes an air inlet pipe 12, which is fixedly connected to the lower surface of the limiting housing 1. A first air groove 13 is formed inside the limiting housing 1. A second air groove 14 is formed at the upper end of the first air groove 13. A sealing piston head 15 is provided on the inner wall of the second air groove 14. A linkage support column 16 is fixed to one end of the sealing piston head 15. Air is inflated into the first air groove 13 through the air inlet pipe 12. The gas is distributed to each L-shaped second air groove 14 through the first air groove 13, pushing the sealing piston head 15 to slide along the second air groove 14. The sealing piston head 15 drives the linkage support column 16 to push the pressing clamp 10 to move.

[0025] The surface of the limiting housing 1 is provided with an inflation linkage mechanism. The air inlet pipe 12 is connected to the first air groove 13, which is an annular design. The second air groove 14 is an L-shaped design, and one end of the second air groove 14 penetrates the inner wall of the cavity of the limiting housing 1. The sealing piston head 15 is slidably connected to the second air groove 14. One end of the linkage support column 16 is fixedly connected to the surface of the pressing clamp 10. The pressing clamp 10 clamps the outer shell under the guidance of the supporting slide column 9. The anti-slip rubber block 11 enhances the friction and ensures stability. After installation, the gas is released, and the springs at the supporting slide column 9 and the positioning plug 5 are reset, driving all components back to their initial state, making it easy to remove the fan.

[0026] Working principle: When using the auxiliary device for installing this fan, pull the fixed base 4 to slide along the support column 2. The positioning block 5 is locked into the positioning groove 3 under the action of the spring. Place the fan shell on the support baffle 8. The buffer slide 7 slides down along the limiting slot 6 and compresses the spring to achieve buffering and shock absorption. Then, the automatic clamping is completed through the air-inflating linkage mechanism. The gas enters the annular first air groove 13 through the air inlet pipe 12 and is then distributed to each second air groove 14. This pushes the sealing piston head 15 to move the linkage column 16, so that the pressing clamp 10 clamps the shell under the guidance of the support slide 9. The anti-slip rubber block 11 enhances stability. After installation, release the gas. The springs at the support slide 9 and the positioning block 5 drive each component to reset, and the fan can be taken out, which increases the overall practicality.
