Winding drum processing tooling

The utility model discloses a winding drum processing tooling, which comprises a guide shaft. Ring seats are fixedly sleeved on the guide shaft, at least three supporting devices are axially distributed on each ring seat, each supporting device comprises a base and a supporting rod, wherein each base is fixedly connected with the corresponding ring seat, each supporting rod is telescopic radially, the inner end of each supporting rod is connected with the corresponding base, the outer end of each supporting rod is a supporting end used for supporting an inner hole wall of a winding drum, and each supporting device is provided with a limiting mechanism used for limiting the supporting rod. The winding drum processing tooling adopts the technical scheme including that each ring seat is provided with the supporting devices, the radially telescopic supporting rods on the supporting devices are adaptable to inner apertures of different winding drums, the ring seats are located at different position on the guide shaft so as to be adaptable to lengths of the different winding drums, accordingly only the guide shaft and the ring seats are required to be designed on the winding drum processing tooling, and the winding drum processing tooling avoids problems of large occupied space and increased processing cost due to the fact that a large quantity of mandrels are adopted.
