Description

Technical Field

[0001] The utility model relates to the technical field of automobile fan balancing, in particular to a fan balancing clip installation device. Background Art

[0002] In order to prevent the car engine temperature from being too high while the car is driving, which will affect the service life of the car, it is necessary to use coolant to cool the car engine. At this time, the car cooling module is needed to dissipate the heat of the car coolant to ensure the normal driving of the car. The car cooling module needs to use a fan to increase the heat dissipation speed. The fan structure includes an impeller. Usually, the impeller is injection molded. During the injection molding process, the plastic shrinks unsteadily due to uneven heating or cooling. In this way, it will be difficult to keep the thickness of the blades consistent, causing deviations in the balance of the blades during rotation, and then the rotation of the impeller will be accompanied by greater vibration, which will cause abnormal noise during the operation of the fan and affect the driving comfort.

[0003] In order for the car cooling fan to work well, the dynamic balance performance of the car cooling fan must be guaranteed. Therefore, before installing the car cooling fan on the car, the dynamic balance performance of the car cooling fan must be tested to ensure the stability of the car cooling fan during operation. By adding a balance clip to the fan blade, the balance amount of the fan can be adjusted to ensure the overall balance of the fan impeller to achieve the best use state. However, the traditional balance clip is pressed directly onto the fan blade by hand. Since the balance clip has barbs to prevent it from falling off, a large force needs to be applied during installation. In addition, the balance clip is small in size and not easy to exert force, making installation difficult.

[0004] Therefore, there is an urgent need for a fan balancing clamp installation device to solve the above problems. Utility Model Content

[0032] like Figure 1 As shown, the fan balancing clamp installation device of this embodiment includes a blade positioning member 1, a clamping and moving mechanism 2 and a support member 3. The blade positioning member 1 can abut against one end of the blade. The clamping and moving mechanism 2 includes a clamping member 21 and a guide member 22, the clamping member 21 is spaced apart from the blade positioning member 1, the guide member 22 is connected to one end of the clamping member 21 away from the blade positioning member 1, the clamping member 21 is used to clamp the balancing clamp 100, and the clamping and moving mechanism 2 can approach and move away from the blade positioning member 1. The support member 3 includes a support portion 31 and a first protrusion 32, the first protrusion 32 is located at one end of the support portion 31, the blade positioning member 1 is connected to the other end of the support portion 31, the first protrusion 32 and the blade positioning member 1 are located on the same side of the support portion 31, and the guide member 22 is slidably connected to the first protrusion 32.

[0033] The present embodiment provides a fan balancing clamp installation device. After the balancing clamp 100 is fixed by the clamping member 21, the fan blade positioning member 1 is abutted against one end of the fan blade on which the balancing clamp 100 needs to be installed. The guide member 22 is moved so that the clamping member 21 drives the balancing clamp 100 away from the fan blade positioning member 1 until the distance between the balancing clamp 100 and the fan blade positioning member 1 is greater than the width of the fan blade. After the opening of the balancing clamp 100 is aligned with the edge of the fan blade, the guide member 22 is moved to move the balancing clamp 100 toward the fan blade, so that the balancing clamp 100 can be clamped onto the fan blade. The fan balancing clamp installation device uses a clamping member 21 to fix the balancing clamp 100, and realizes the movement of the balancing clamp 100 by moving the guide member 22 relative to the first protrusion 32, so that the balancing clamp 100 can be installed on the fan blade, so that the original need to directly press the balancing clamp 100 by hand is changed to applying pressure to the guide member 22, thereby increasing the area of ​​​​applying pressure, improving the convenience of assembly operations, and reducing the difficulty of installing the balancing clamp 100. The fan balancing clamp installation device is positioned on the fan blade using the fan blade positioning member 1, which can reduce the impact of hand shaking on the installation and improve the stability during installation.

[0034] In this embodiment, the first protrusion 32 is provided with a guide hole, the guide member 22 is provided as a guide post, and the guide member 22 is inserted into the guide hole. The structure is simple and the movement of the guide member 22 is convenient.

[0035] Furthermore, the clamping moving mechanism 2 also includes an abutment portion 23, which is connected to the top of the guide member 22. The cross-sectional area of ​​the abutment portion 23 is larger than the cross-sectional area of ​​the guide hole. The lower surface of the abutment portion 23 can abut against the upper surface of the first protrusion 32 to prevent the guide member 22 from being displaced too much when moving downward, causing the guide member 22 to be detached from the first protrusion 32.

[0036] Optionally, the clamping moving mechanism 2 also includes a spring 24, which is connected between the abutment portion 23 and the first protrusion 32, and the spring 24 is sleeved outside the guide member 22. When the fan balancing clamp installation device is used to complete the installation of a balancing clamp 100, the spring 24 can push the abutment portion 23 away from the first protrusion 32, thereby resetting the guide member 22 and facilitating the clamping of the next balancing clamp 100.

[0037] Further, the clamping member 21 includes a connecting portion 211 and at least two claws 212, and the connecting portion 211 is connected to the bottom of the guide member 22.

Preferably, in order to prevent the guide member 22 from loosening after being connected to the connecting portion 211, the connecting portion 211 is also provided with an anti-loosening hole, and the anti-loosening hole can be penetrated with an anti-loosening pin or threadedly connected with a locking screw to ensure the stability between the guide member 22 and the connecting portion 211. The claws 212 are connected to the bottom of the connecting portion 211, and the balancing clamp 100 can be limited between the two claws 212 to prevent the movement and rotation of the balancing clamp 100, which is convenient for positioning the balancing clamp 100. In some embodiments, the claws 212 are set to two, and in some other embodiments, the claws 212 can also be set to three, four, etc. It should be noted that, in the present embodiment, the clamping member 21 is made of nylon material, which has good sliding properties and excellent wear resistance, thereby ensuring the service life and reducing the damage to the plastic fan blades when installing the balancing clamp 100.

[0038] Preferably, the clamping and moving mechanism 2 further comprises a magnetic element, which is connected to the bottom of the clamping element 21 . In the present embodiment, the magnetic element is disposed between the two claws 212 to attract the balancing clamp 100 .

[0039] Furthermore, the clamping and moving mechanism 2 further includes a pushing member 25, which is connected between the clamping member 21 and the guide member 22 to facilitate the movement of the clamping member 21. Specifically, the cross-sectional area of ​​the pushing member 25 is larger than the cross-sectional area of ​​the clamping member 21. When the fan balancing clamp installation device is used, the balancing clamp 100 can be pressed onto the fan blade by pressing the fan blade positioning member 1 and the pushing member 25. The pressing of the balancing clamp 100 can be completed with only one hand, which simplifies the working process and improves the working efficiency.

[0040] Furthermore, the clamping moving mechanism 2 also includes an adjusting washer 26, which is located between the first protrusion 32 and the clamping member 21, and the adjusting washer 26 is sleeved on the guide member 22. By setting adjusting washers 26 of different thicknesses, a certain distance can be preset between the clamping member 26 and the first protrusion 32, so that when the fan balancing clamp installation device is in the initial position, the distance between the clamping member 26 and the fan blade positioning member 1 is the most suitable distance, reducing adjustments during installation and facilitating quick installation of the balancing clamp 100.

[0041] Preferably, the support member 3 further includes a second protrusion 33, which protrudes from one end of the support member 31 away from the first protrusion 32, and the second protrusion 33 and the first protrusion 32 are located on the same side of the support member 31, and the blade positioning member 1 can abut against the second protrusion 33 to limit the position of the blade positioning member 1 and improve the structural strength of the fan balance clamp installation device. In this embodiment, the blade positioning member 1 abuts against the second protrusion 33 and is installed on the support member 31 by bolts, which is easy to install and replace.

[0042] Furthermore, the fan blade positioning member 1 is provided with a positioning groove 11, and the fan blade can be limited in the positioning groove 11. Preferably, the positioning groove 11 is a V-shaped groove, and the fan blade can be limited at the bottom of the V-shaped groove to limit the fan blade and prevent the fan blade from shaking during installation. In this embodiment, the fan blade positioning member 1 is set to a nylon material. The nylon material has good sliding properties and excellent wear resistance, which can ensure the service life while reducing the damage to the plastic fan blade when installing the balance clip 100.

[0043] When using the fan balancing clamp installation device provided in this embodiment, first use the magnetic suction member to fix the balancing clamp 100. At this time, the balancing clamp 100 is limited between the two claws 212 to prevent the balancing clamp 100 from rotating. The fan blade is limited in the positioning groove 11 of the fan blade positioning member 1. The clamping member 21 is close to the fan blade so that the opening of the balancing clamp 100 is aligned with the fan blade. Multiple fingers are pressed respectively below the second protrusion 33 and above the pushing member 25, and pressure is applied to the pushing member 25 so that the balancing clamp 100 is clamped on the fan blade. The pushing member 25 is released, and the guide member 22 is reset under the action of the spring 24, so that the fan blade is detached from the positioning groove 11, and the installation of the balancing clamp 100 is completed.
