[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that the description of these embodiments is intended to aid in understanding the invention, but does not constitute a limitation thereof. The specific structural and functional details disclosed herein are merely for describing exemplary embodiments of the invention. However, the invention can be embodied in many alternative forms and should not be construed as being limited to the embodiments described herein.

[0026] like Figure 1 As shown, a steel coil defect handling fixture includes two operating parts arranged on both sides of the steel coil. Each operating part includes a base 1, a connecting rod 2, and a clamping plate 3, wherein:

[0027] The base 1 can be made movable so that it can be moved accordingly according to the axial width of the steel coil to accommodate the processing of more specifications of steel coils and improve applicability.

[0028] The middle part of the connecting rod 2 is hinged to the base 1. When one end of the connecting rod 2 is displaced to a certain extent, the other end of the connecting rod 2 is also displaced to the same extent.

[0029] The clamp 3 is movably located at one end of the connecting rod 2.

[0030] The two clamping plates 3 are used to clamp the two ends of the steel coil in the axial direction. The operating part also includes a first adjusting part 4 for adjusting the distance between the two clamping plates 3. When the two operating parts are arranged opposite each other, the two clamping plates 3 can be constrained to move closer to each other by adjusting the first adjusting part 4. Thus, when the steel coil is located between the two clamping plates 3, the two clamping plates 3 can be clamped on the axial end face of the steel coil. It is worth noting that the first adjusting part 4 can pass through the channel in the center of the steel coil or connect the two clamping plates from the outside of the steel coil.

[0031] The working principle of the embodiment is that: one operation part is arranged on each side of the steel coil, each operation part comprises a base 1, a connecting rod 2 is hinged on the base 1, a chuck 3 is movably arranged at one end of the connecting rod 2, and the operation part further comprises a first adjusting part 4 for adjusting the distance between the two chucks 3; when the inner tower appears in the inner ring of the steel coil or the overflow edge appears in the outer ring, the two operation parts are moved to the two sides of the steel coil, and the two chucks 3 are clamped at the two axial ends of the steel coil, then the distance between the two chucks 3 is adjusted through the first adjusting part 4, until the two chucks 3 are clamped on the two side end faces of the steel coil respectively, so that the chuck 3 extrudes the inner tower appearing in the inner ring of the steel coil or the overflow edge appearing in the outer ring in the process of approaching each other, thereby realizing the rapid treatment of the defects of the steel coil, the treatment process does not need to involve the lifting appliance, the treatment efficiency is higher, and the secondary damage to the steel coil during the treatment of the defects of the steel coil is avoided.

[0032] Further, on the basis of the above embodiment, the first adjusting part 4 is provided with a plurality of first adjusting parts 4, which are uniformly distributed in the circumferential direction along the center line of the chuck 3.

[0033] Further, on the basis of the above embodiment, the first adjusting part 4 is a threaded tensioning part, which adjusts the tension of the first adjusting part 4 in a threaded connection manner, so as to more accurately and stably control the distance between the two chucks 3.

[0034] The threaded tensioning part can be provided as a bolt or a lead screw.

[0035] Further, on the basis of the above embodiment, the operation part further comprises a second adjusting part 5, the second adjusting part 5 is arranged between the connecting rod 2 and the base 1, and is used for adjusting the inclination angle of the connecting rod 2; when the height of the position where the chuck 3 is located does not match the height of the steel coil, one end of the connecting rod 2 is displaced by operation, until the chuck 3 at the other end of the connecting rod 2 moves to the appropriate position; in order to reduce the manual intervention to maintain the connecting rod 2, the displacement of the connecting rod 2 relative to the base 1 is maintained by the second adjusting part 5, and the reset of the connecting rod 2 is limited, so as to facilitate the disassembly of the first adjusting part 4 on the chuck 3.

[0036] Further, on the basis of the above embodiment, the second adjusting part 5 comprises a screw rod 51, a sleeve 52 and a nut 53, one end of the screw rod 51 is hinged with the connecting rod 2, the sleeve 52 and the nut 53 are sequentially sleeved on the side of the screw rod 51 away from the connecting rod, the nut 53 is in threaded connection with the screw rod 51, and the sleeve 52 is rotatably arranged on the base 1.

[0037] When the second adjusting part 5 adjusts the inclination angle of the connecting rod 2, the position relationship between the screw rod 51 and the nut 53 is adjusted, and the distance between the one end of the screw rod 51 connected with the connecting rod 2 and the nut 53 is controlled. Since the weight of the one end of the connecting rod 2 close to the chuck 3 is greater than that of the other end, the one end of the connecting rod 2 far from the chuck 3 has a tendency to rise under no external force. At this time, the distance between the one end of the connecting rod 2 and the sleeve 52 does not change under the restriction of the nut 53 and the sleeve 52, so as to keep the relative stability of the connecting rod 2. The sleeve 52 is rotatably arranged on the base 1, so as to always be sleeved on the screw rod 51 in the process of changing the distance between the sleeve 52 and the connecting rod 2.

[0038] Further, on the basis of the above embodiment, the operating part further comprises a third adjusting part 6 arranged on the connecting rod 2 and used for adjusting the inclination angle of the chuck 3. Since the connecting rod 2 is displaced, the angle between the center line of the connecting rod 2 and the end face of the steel coil changes, and correspondingly, the angle between the chuck 3 and the end face of the steel coil also changes. The inclination angle of the chuck 3 is adjusted by the third adjusting part 6, so that the chuck 3 can be kept in contact with the end face of the steel coil at different height positions.

[0039] Further, on the basis of the above embodiment, the third adjusting part 6 comprises a handle 61 and a positioning part 62. The positioning part 62 is fixedly arranged on the connecting rod 2, and the handle 61 is threadedly connected with the positioning part 62.

[0040] When the third adjusting part 6 adjusts the inclination angle of the chuck 3, the position relationship between the handle 61 and the positioning part 62 is adjusted, and the distance between the one end of the handle 61 and the positioning part 62 is controlled. The one end of the handle 61 close to the chuck 3 is abutted on the chuck 3, the one end of the chuck 3 is hinged with the connecting rod 2, and the chuck 3 is pushed out along with the continuous rotation of the handle 61, so as to adjust the chuck 3 to be pressed on the end face of the steel coil.

[0041] Further, on the basis of the above embodiment, the one end of the connecting rod 2 far from the chuck 3 is provided with a holding part, so as to facilitate holding the holding part and adjusting the position height of the one end of the connecting rod 2.

[0042] Further, on the basis of the above embodiment, the base 1 is provided with a roller 7 at the bottom, so as to facilitate the overall movement of the base 1 to the two sides of the steel coil.

[0043] Further, on the basis of the above embodiment, the outer diameter of the chuck 3 is not less than the outer diameter of the steel coil, so that the chuck 3 can directly cover the inner tower appeared on the inner circle of the steel coil or the overflow edge appeared on the outer circle.
