Outer cylinder positioning structure with adjusting function

The utility model relates to the technical field of outer cylinder positioning, in particular to an outer cylinder positioning structure with an adjusting function, which comprises a bottom plate, first two-way screws are arranged on the inner walls of the two ends of the bottom plate, a servo motor is mounted at one end of the bottom plate, and rotating mechanisms are arranged at the two ends of the top of the bottom plate. And clamping mechanisms are symmetrically arranged between the two rotating mechanisms. The first two-way screw is driven by the servo motor to rotate, so that the distance between the two rotating mechanisms can be adjusted, the two ends of rubber rollers with different lengths can be abutted according to different distances between the two rotating mechanisms, the device can be suitable for production of the rubber rollers with different lengths, the device has good flexibility, and the production efficiency is improved. After a coating rubber sheet is pasted on a metal core of the rubb
