They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0027] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Example

[0028] This utility model provides an automated polishing device for fiber composite automotive wheel hub inserts. Please refer to [link / reference]. Figure 1-4 The system includes a polishing robot 100 and a wheel hub insert fixture 200. The wheel hub insert fixture 200 includes multiple polishing jigs 1 for loading wheel hub inserts 10 to be polished. The polishing head 101 at the end of the polishing robot 100 polishes the surface of the wheel hub inserts 10 fixed in the polishing jig 1. The polishing jig 1 includes a jig base 2, a mold core profile block 3, and an over-polishing protection mechanism 4. The wheel hub inserts 10 are placed on the mold core profile block 3, and the over-polishing protection mechanism 4 is located on one side of the mold core profile block 3 and can abut against the side edge of the wheel hub inserts 10 to prevent them from shifting during the polishing process.

[0029] For details, please continue reading. Figure 2-4 The mold core molding blocks 3 are multiple in number and arranged around the wheel hub insert 10. Suction cups 5 are installed in each of the multiple mold core molding blocks 3 to adhere and fix the back of the wheel hub insert 10 by negative pressure. A pressure gauge 9 is installed on one side of the wheel hub insert tooling 200. The pressure gauge 9 is connected to the suction cups 5 via a pipe and is used to display the adsorption pressure of the suction cups 5.

[0030] Furthermore, the suction cup 5 is fixedly mounted on the fixture base 2 via the suction cup bracket 6.

[0031] Specifically, such as Figure 4 As shown, the over-throw protection mechanism 4 includes an over-throw protection block 401, a drive cylinder 402, and a slide rail 403; the bottom of the over-throw protection block 401 is mounted on the slide rail 403 and can slide horizontally along the slide rail 403; while the drive cylinder 402 is located on the side of the over-throw protection block 401 away from the mold core copying block 3, and pushes the over-throw protection block 401 to slide horizontally under the action of the drive cylinder 402.

[0032] Furthermore, the over-polishing protection block 401 is L-shaped; its vertical portion abuts against the side edge of the hub insert 10, and its horizontal portion is connected to the slide rail 403. The structure of the over-polishing protection block 401, identical to that of the hub insert 10, ensures effective contact, preventing vibration and displacement during polishing. Additionally, since the surface area of ​​the hub insert 10 is small, while the robot polishing head has a relatively large area, the robot polishing head is prone to downward displacement or even collision when polishing product edges. The over-polishing protection block 401 can withstand the force of the polishing head extending beyond the hub insert to avoid impact, further improving production quality.

[0033] In one embodiment, multiple polishing fixtures 1 are spaced apart and mounted on the same inclined support plate 7, so that the polishing head 101 at the end of the polishing robot 100 can polish the surface of the wheel hub insert 10 fixed in the polishing fixture 1. The wheel hub insert polishing fixture 200 is easy to assemble and disassemble, simple to operate, lightweight, flexible, and easy to transport. Its application requires low operator skill levels, greatly reducing operator workload. The wheel hub insert polishing fixture 200 has a simple and compact overall structure, is easy to install and maintain, has low manufacturing costs, and is reliable in operation. The wheel hub insert polishing fixture 200 is widely used in the molding process of composite material wheel hub insert parts.

[0034] Furthermore, the inclined support plate 7 is installed on the stainless steel tray 8 to receive the polishing liquid, and the stainless steel tray 8 is provided with a water outlet for discharging the polishing liquid.

[0035] This automated polishing device for fiber composite automotive wheel hub inserts is suitable for continuous, uninterrupted industrial production. It features a suction cup structure to ensure the wheel hub inserts do not shift during the pressurization process, guaranteeing the flatness of the inner surface of the parts. Furthermore, it incorporates a mold core conforming block structure that is identical to the wheel hub insert structure, ensuring effective contact between them and preventing vibrations during production, thus further improving production quality.

[0036] The above description is only a description of the preferred embodiment of the present utility model and is not intended to limit the scope of the present utility model in any way. Any changes or modifications made by those skilled in the art based on the above disclosure shall fall within the protection scope of the claims.
