Detailed Description

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

Example (b): referring to fig. 1 and 2, a fixing device 4 on a steel plate uncoiler comprises an uncoiler base 11, and a main shaft 2 is arranged on the uncoiler base 1. One end of the main shaft 2 far away from the uncoiler base 1 is fixedly connected with a support shaft 3, and the support shaft 3 and the main shaft 2 are coaxially arranged. The diameter of back shaft 3 is less than main shaft 2, is equipped with fixing device 4 on the back shaft 3, and fixing device 4 is equipped with two along the periphery wall of back shaft 3. The two fixing devices 4 are symmetrically arranged about the center of the supporting shaft 3, and the two fixing devices 4 are used for positioning a steel plate sleeved on the main shaft 2.

Referring to fig. 2, the fixing device 4 includes a slide groove 401 formed in the support shaft 3, and a slide holder 402 slidably disposed in the slide groove 401. The length direction of the sliding groove 401 is parallel to the central axis direction of the supporting shaft 3, the ear plate seat 5 is welded on the sliding seat 402, and the connecting plate 6 is hinged on the ear plate seat 5. One end of the connecting plate 6, which is far away from the ear plate seat 5, is connected with an electromagnetic chuck 7, the electromagnetic chuck 7 is hinged with the connecting plate 6, and the electromagnetic chuck 7 is connected with an external control system through an electric wire.

Referring to fig. 2, the worker puts the steel plate on the main shaft 2, and then adjusts the sliding seat 402 to slide in a direction approaching the main shaft 2. The adjusting connecting plate 6 rotates around the ear plate seat 5, so that the electromagnetic chuck 7 is adsorbed on the side surface of the steel plate. At the moment, the switch of the external power supply is turned on, and the electromagnetic chuck 7 is tightly adsorbed on the side face of the steel plate, so that the steel plate is positioned.

Referring to fig. 4, in order to reduce the phenomenon that the sliding seat 402 is separated from the sliding groove 401 when the sliding seat 402 slides along the sliding groove 401. Therefore, the two sides of the sliding seat 402 are fixedly connected with the positioning strips 8 (the positioning strips 8 and the sliding seat 402 are integrally formed), and the inner side wall of the sliding groove 401 is provided with the positioning groove 9. The positioning strip 8 is matched and slides in the positioning groove 9, so that the possibility that the sliding seat 402 is separated from the sliding groove 401 is reduced.

Referring to fig. 4, a positioning plate 10 is welded on the sliding seat 402, a positioning bolt 11 penetrates through the positioning plate 10, and the positioning bolt 11 penetrates through the positioning plate 10 and abuts against the bottom of the sliding groove 401. After the sliding seat 402 slides to a proper position, a worker adjusts the positioning bolt 11 to abut against the bottom of the sliding groove 401, so that the position of the sliding seat 402 is fixed, and the possibility that the sliding seat 402 and the sliding groove 401 slide relatively due to the reaction of the connecting plate 6 on the sliding seat 402 is reduced.

Referring to fig. 4 and 5, in order to further make the electromagnetic chuck 7 tightly fit on the side surface of the steel plate, a support plate 12 is hinged in the middle of the connecting plate 6, and the support plate 12 is positioned between the electromagnetic chuck 7 and the ear plate seat 5. The support plate 12 is located on one side of the connecting plate 6 close to the sliding groove, the sliding seat 402 is provided with an accommodating groove 13, and an accommodating block 14 slides in the accommodating groove 13. The staff adjusts connecting plate 6 and rotates to the direction of keeping away from sliding seat 402 for electromagnet 7 adsorbs closely the side at the steel sheet, and at this moment, extension board 12 slides to the one end of holding tank 13, and extension board 12 supports in the below of connecting plate 6, improves connecting plate 6's positional stability, makes electromagnet 7 support the one side at the steel sheet more steadily.

Referring to fig. 5, a first magnet block 15 and a second magnet block 16 are bonded to both sides of the receiving block 14, a third magnet block 17 and a fourth magnet block 18 are bonded to both ends of the receiving groove 13, the first magnet block 15 is fitted to the third magnet block 17, and the second magnet block 16 is fitted to the fourth magnet block 18. When the support plate 12 is supported below the connecting plate 6, the first magnet block 15 and the third magnet block 17 are attracted and tightly attached together, so that the stability of the support plate 12 supported below the connecting plate 6 is improved. When the staff adjusts the electromagnetic chuck 7 and breaks away from the side of steel sheet, at this moment, hold the piece 14 and move to the direction that is close to fourth magnet piece 18, improved the staff and adjusted the gliding convenience of holding piece 14.

Referring to fig. 5, in order to prevent the receiving block 14 from being removed from the receiving groove 13. The cross section of the accommodating block 14 is T-shaped, and the accommodating block 14 with the T-shaped cross section has a function of limiting the sliding in the accommodating groove 13.

The implementation principle of the embodiment is as follows: the staff wears the steel sheet cover on main shaft 2, then adjusts sliding seat 402 and slides to the direction that is close to main shaft 2, rotates connecting plate 6 and slides to the direction of keeping away from sliding seat 402 for electromagnet 7 closely laminates in the side of steel sheet. Then adjust positioning bolt 11 and support tightly at the tank bottom of sliding tray, play the effect of injecing to the position of sliding seat 402, then adjust the extension board 12 to the one end that slides to holding tank 13, extension board 12 supports in the below of connecting plate 6, improves the positional stability of connecting plate 6 for electromagnet 7 supports in one side of steel sheet more steadily.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
