Description

Technical Field

[0001] This utility model relates to the field of automotive wheel hub technology, specifically a wheel hub adhesive sound-absorbing cotton installation device. Background Technology

[0002] Currently, sound-absorbing cotton is a commonly used material that utilizes the porous structure of a sponge to achieve sound absorption and noise reduction. It is widely used in automobile manufacturing processes, including in engine compartments, door panels, and roof linings. Research shows that applying sound-absorbing cotton to the wheel rims can effectively reduce cavity vibration and tire noise, reducing overall vehicle noise by approximately 10 dB. Currently, applying sound-absorbing cotton to wheel rims is generally done manually, which is not only complex but also makes it difficult to ensure consistent application. Utility Model Content

[0003] In view of this, the present invention aims to provide a wheel hub bonding and sound-absorbing cotton installation device, which can improve the consistency and stability of bonding and reduce the difficulty of operation for production personnel.

[0004] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0005] A device for installing sound-absorbing cotton on a wheel hub includes a base, a positioning beam mounted on the base, a rear positioning roller and a front positioning roller mounted on the positioning beam for clamping the wheel hub, a pressing roller mounted on the base for pressing the sound-absorbing cotton, an adjusting nut connected to the pressing roller for adjusting the position of the pressing roller, and a pressure sensor connected to the pressing roller for detecting and displaying pressure.

[0006] In some embodiments, the rear positioning roller and the front positioning roller are laterally movable on the positioning beam to accommodate hubs of different widths.

[0007] In some embodiments, the adjusting nut is used to adjust the pressure between the press-fit roller and the outer rim of the hub.

[0008] In some embodiments, the pressure sensor displays in real time the pressure applied by the press roller to the outer rim of the hub. Attached Figure Description

[0013] It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0014] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings and embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0015] The following is for reference. Figure 1 The wheel hub bonding sound-absorbing cotton installation device of this utility model is described in conjunction with the embodiments.

[0016] A device for installing sound-absorbing cotton on wheel hubs includes a base 1, on which a positioning beam 5 is connected. A rear positioning roller 2 and a front positioning roller 3 are positioned on the positioning beam 5 corresponding to the inner and outer rim positions of the wheel hub, for fixing the wheel hub. The rear positioning roller 2 and the front positioning roller 3 on the positioning beam 5 can move laterally according to the width of the wheel hub rim, for fixing wheel hubs of different sizes. The rear positioning roller 2 and the front positioning roller 3...

[0017] A pressing roller 4 is mounted on the base 1. The position of the pressing roller 4 can be adjusted by adjusting the nut 6. A pressure sensor 7 is connected to the pressing roller 4, which can display the pressure generated when the pressing roller 4 contacts the outer rim of the wheel hub in real time, and the pressure can be regulated by adjusting the nut 6.

[0018] Applying sound-dampening cotton to wheel rims has become a popular method for reducing tire noise during driving in recent years. Specifically, this involves an installation device for applying sound-dampening cotton to wheel rims, including a base 1, a rear positioning roller 2, a front positioning roller 3, a pressing roller 4, a positioning beam 5, an adjusting nut 6, and a pressure sensor 7. The front and rear positioning rollers 2 are respectively mounted on the positioning beam 5. The positioning rollers can move laterally left and right according to the width of the wheel rim to position the rim. The pressure of the positioning rollers can be adjusted by adjusting the nut 6, and the real-time pressure data is displayed on the pressure sensor 7. Under a fixed pressure, rotating the wheel rim automatically presses the sound-dampening cotton firmly onto the outer rim of the wheel rim using the pressing roller 4.

[0019] Compared with existing technologies, the wheel hub bonding sound-absorbing cotton installation device of this utility model has the following advantages:

[0020] The wheel hub sound-absorbing cotton installation device disclosed in this utility model can not only adjust the positioning position according to the wheel hub size and width, but also ensure consistent installation pressure by adjusting the pressure of the positioning roller. Under a fixed installation pressure, it can ensure the consistency and stability of the sound-absorbing cotton adhesion and reduce defective products caused by manual operation.

[0021] Compared to manual application of sound-absorbing cotton, this method features uniform roller pressure, improving the stability of the sound-absorbing cotton application and reducing the defect rate caused by manual operation. It overcomes the problems of high difficulty, low efficiency, and poor stability associated with applying sound-absorbing cotton to wheel hubs. The position of the rollers on the positioning beam can be adjusted to meet the application requirements of wheel hubs of different sizes, and the stability of the sound-absorbing cotton application is ensured by adjusting the pressure of the positioning rollers.
