step five: the V-shaped tool mirror image separated from the left side rotating wheel is arranged on the right side rotating wheel, the inner side surface of the long support arm of the scribing base (1) is attached to the end surface of the rotating wheel, and the inner side surface of the swing arm (4) is attached to the conical surface of the delta angle of the rotating wheel; the strong magnet (6) is adsorbed in a through groove of the scribing base (1), and the strong magnet (6), the scribing base (1) and the swing arm (4) are integrally adsorbed on the right side rotating wheel by the attraction of the strong magnet (6) and are tightly attached to the rotating wheel;
Step six: operating spinning equipment to enable the conical vertex of a scribing needle (3) on the right spinning roller to be close to the indentation on the curved bus mandrel, and adjusting the coordinates of the right spinning roller until the coordinates are completely overlapped, and recording the coordinates of the right spinning roller at the position at the moment; the coordinate position recorded for 2 times is the coordinate reference when the left and right spinning wheels are completely synchronous.
8. The method for using the detection tool for accurate positioning of the spinning wheel according to claim 7, wherein the method comprises the following steps: in the fourth step, the width of the indentation on the circumference of the mandrel is not more than 0.05mm, and the depth is not more than 0.03mm.
9. The method for using the detection tool for accurate positioning of the spinning wheel according to claim 7, wherein the method comprises the following steps: the coordinate references when the left and right hand spinning wheels are fully synchronized can be used for process, as well as operator reference and compensation references when programmed.
