[0027] The specific implementation process of the utility model is as follows: the device is used for clamping a flat welding strip reel. The flat welding strip reel is placed on the placement platform 2, and the pull rod 17 is pulled to make the limit block 8 completely leave the limit groove. The handle 5 is manually pulled to drive the adjustment rack 4 to slide. The meshing connection between the adjustment rack 4 and the gear 7 is made to rotate the gear 7, thereby driving the turntable 11 to rotate. The rotation of the turntable 11 makes the connecting rod 12 slide and fit on the outer peripheral surface of the turntable 11, thereby driving the clamping block 3 to rotate accordingly. The rotation of the turntable 11 makes the connecting rod 12 slide and fit on the outer peripheral surface of the turntable 11, thereby driving the clamping block 3 Perform a corresponding slight rotation, one end of which is clamped and fitted with the flat welding strip disc workpiece, loosen the pull rod 17, and a plurality of arrays of equally spaced limit grooves are opened on one side of the adjustment rack 4. The limit block 8 and the limit groove have the same shape and size, which ensures the stable cooperation between the adjustment rack 4 and the limit block 8, and has good stability. The aluminum alloy has good wear resistance, can resist the friction and wear between the flat welding strip disc and the placement platform 2, and prolongs the service life of the placement platform 2. It also has good corrosion resistance and can resist the corrosive medium in the environment, and maintains the stability and reliability of the placement platform 2.

[0028] Furthermore, the operator fixes the anti-twist device 200 in a suitable position as needed, and connects or fixes it to other components through the circular hole 1 208 and the circular hole 205. When the welding strip is parallel to the surface of the new disk and the new disk starts to reel, the clamping device 100 maintains the position of the welding strip unchanged through a stable clamping force, and the anti-twist device 200 prevents the welding strip from twisting during the winding process. Through the coordinated rotation of the rotating ring 201 and the mounting base 1, as well as the support and positioning of the vertical rod 1 202, the vertical rod 203 and other components, the anti-twist device 200 can ensure that the welding strip remains stable during the winding process and avoids the occurrence of twisting. The coordinated use of the clamping device 100 and the anti-twist device 200 can achieve the parallel bonding of the welding strip to the surface of the new disk, and ensure that when the new disk starts to reel, the welding strip can be wound around the new disk smoothly and without twisting. This coordinated use improves the accuracy and stability of the welding strip winding, which is of great significance for improving production efficiency and product quality.
