Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of steel sleeve inner diameter grading detection tool. BACKGROUND

[0002] At present, in the production of aluminum alloy strip, intermediate transfer and delivery transportation process in aluminum processing industry, core sleeve coiling form is used. Because the sleeve has certain supporting capacity, it can ensure that the aluminum alloy strip will not be scrapped due to collapse and deformation during production, intermediate transfer and delivery transportation. According to the different materials, the widely used sleeve types mainly include cast aluminum sleeve, steel sleeve and paper sleeve. The steel sleeve has high production cost, large weight and large area, and has large difference in heat conduction with aluminum alloy. After long-term use, deformation and depression may occur, and the steel sleeve with deformation or depression may further reduce the contact area with the reel and cause slipping. Therefore, it is necessary to regularly detect the inner and outer surfaces of the steel sleeve. At present, the inner circle detection is generally detected by an inside micrometer. The operator needs to climb into the steel sleeve for detection, and the detection is carried out by multiple-point detection, which cannot completely measure the defects on the entire inner surface. Therefore, the operation is complicated, but the detection effect is not good, and improvement is needed. SUMMARY

[0003] In view of the shortcomings of the prior art, the technical problem to be solved by the utility model is to provide a steel sleeve inner diameter grading detection tool, which is not only reasonable in structure, but also efficient and convenient.

[0004] To solve the above technical problems, the technical scheme of the utility model is as follows: a steel sleeve inner diameter grading detection tool, comprising a detection seat, a plurality of suction cups are fixed on one side of the detection seat, and a detection disc set is adsorbed by the suction cups. The detection disc set comprises two coaxially arranged discs, and a plurality of connecting rods are fixedly connected between the two discs. A handheld long rod is fixedly connected to the other side of the detection seat.

[0005] Further, a through hole is formed in the center of the detection seat for the end of the handheld long rod to pass through.

[0006] Further, the end of the handheld long rod is provided with external threads, and is screwed and fixed tightly on the detection seat by a nut.

[0007] Further, the two discs have consistent sizes.

[0008] Further, the connecting rods are evenly distributed along the outer edge of the disc, and the two ends of the connecting rod are fixedly connected to the two discs, respectively.

[0009] Further, the detection seat is triangular, the corners of the triangle are rounded, and the sides of the triangle are arc sides concave towards the center. The detection seat is provided with an insertion rod protruding from the corner of the triangle, and the suction cup is fixedly connected to the insertion rod by insertion.

[0010] Compared with the prior art, the present invention has the following advantages: by combining the suction cup with detection discs of different sizes, the inner wall of the steel sleeve can be detected efficiently and conveniently; the two-layer disc can effectively ensure the strength of the disc and avoid skewness when touching the concave point, that is, the axial direction is offset from the central axis of the steel sleeve, which affects the detection accuracy; the overall structure is simple and the operation is convenient.

[0011] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. Attached Figure Description
