Description

Technical Field

[0001] The invention relates to a steel sleeve inner diameter grading detection tool and a working method thereof. Background Art

[0002] At present, the production, intermediate transfer, and delivery and transportation of aluminum alloy strips in the aluminum processing industry all adopt the core sleeve winding form. Because the sleeve has a certain supporting capacity, it can ensure that the aluminum alloy strip will not be scrapped due to collapse or deformation during production, intermediate transfer, and delivery and transportation. According to different materials, the types of sleeves currently widely used mainly include cast aluminum sleeves, steel sleeves, and paper sleeves. The production cost of steel sleeves is high, the weight is large, and the area is large. There is a big difference in thermal conductivity with aluminum alloys. After long-term use, it is easy to deform and dent. If the deformed or dented steel sleeve is used continuously, it is easy to reduce the contact area with the reel and slip. That is, it is necessary to regularly inspect the inner and outer surfaces of the steel sleeve. At present, the inner circle is generally inspected by an internal diameter micrometer. In this inspection method, the staff needs to climb into the steel sleeve for inspection, and the inspection adopts a multi-point inspection method, which cannot fully measure the defects of the entire inner surface. That is, the operation is cumbersome but the inspection effect is poor, which needs to be improved urgently. Summary of the invention

[0006] Furthermore, a groove is provided inwardly on the mating surface of the detection seat and the extension seat, and a spring is provided in the groove.
