Description

Technical Field

[0001] The utility model relates to the technical field of rubber bushing hole expansion inspection, and specifically relates to a rubber bushing hole expansion inspection device. Background Art

[0002] Rubber bushings are shock-absorbing products installed at the hinge points between various parts of the automobile body. Their main shape is generally a hollow cylindrical structure with functions such as load bearing and noise reduction. Before they are installed with automobile parts, they need to use a hole expansion device to expand their inner hole diameter to improve the product's stiffness performance and meet the use and installation requirements. However, after the existing rubber bushing hole expansion device expands the rubber bushing, on the one hand, the rubber bushing will adhere to the hole expansion rod, making it difficult to remove and reducing the hole expansion efficiency. On the other hand, the hole expansion is incomplete, that is, the hole expansion size is unqualified or the hole expansion length is insufficient, and the hole expansion effectiveness cannot be integrated and confirmed.
