The present invention will be described in further detail with reference to the accompanying drawings.

Example (b): referring to fig. 1 and 2, a positioning device on a steel plate uncoiler includes an uncoiler stand 1. A main shaft 2 is arranged on the uncoiler base 1, and a fixed shaft 3 is welded at one end of the main shaft 2, which is far away from the uncoiler base 1. The fixing shaft 3 and the main shaft 2 are coaxially arranged, the diameter of the fixing shaft 3 is smaller than that of the main shaft 2, the fixing shaft 3 is provided with a positioning device 4, and a worker adjusts the positioning device 4 to fix the position of the steel plate.

Referring to fig. 2, the positioning device 4 includes a positioning groove 401 formed on the fixed shaft 3, and a slide block 402 slidably coupled in the positioning groove 401. The length direction of constant axis 3 is followed to constant head tank 401, and the welding has support column 5 on the sliding block 402, and support column 5 vertical welding is on the surface of sliding block 402. Be connected with fixed plate 6 through the bearing rotation between two support columns 5, the one end that support column 5 was kept away from to fixed plate 6 sets up to the arc.

Referring to fig. 3, a limiting device 7 is arranged at one end of the main shaft 2 close to the uncoiler base 1, the limiting device 7 comprises a fixing column 701 welded on the main shaft 2, and the fixing column 701 is perpendicular to the central axis of the main shaft 2. The fixing column 701 is provided with a limiting groove 8, the notch of the limiting groove 8 faces one side of the fixing shaft 3, a limiting block 9 is connected in the limiting groove 8 in a sliding mode, the cross section of the limiting block 9 is T-shaped, a limiting bolt 10 is arranged on the fixing column 701 in a penetrating mode through threads, and the limiting bolt 10 penetrates through the fixing column 701 and is abutted to the limiting block 9.

Referring to fig. 2 and 3, the staff wears the steel sheet and overlaps on main shaft 2, then adjusts stopper 9 and slides along spacing groove 8 for stopper 9 supports tightly in the side of steel sheet, realizes keeping away from the steel sheet one side of main shaft 2 and realizes fixing the position of steel sheet. Then, the adjusting slide block 402 slides in a direction close to the main shaft 2, and the fixing plate 6 is rotated to make one end of the fixing plate 6 abut against the side surface of the steel plate, and the fixing plate 6 abuts against the side surface of the steel plate, thereby further fixing the position of the steel plate.

Referring to fig. 2, in order to further improve the positional stability of the steel plate on the main shaft 2, two positioning devices 4 are provided along the circumferential side wall of the fixed shaft 3, and the two positioning devices 4 are symmetrically disposed about the central axis of the fixed shaft 3.

Referring to fig. 2, in order to facilitate the worker to adjust the fixing plate 6 and fix the position of the steel plate, a positioning cylinder 14 is hinged to the sliding block 402, and an output shaft of the positioning cylinder 14 is hinged to the fixing plate 6.
