Roller tool

The utility model discloses a roller tool, and belongs to the field of machining. The lead screws are provided with threads in opposite directions and are in threaded connection with the driving roller supporting seat and the driven roller supporting seat respectively. And the driving roller shaft is supported on the driving roller supporting seat. And the driven roller shaft is supported on the driven roller supporting seat. The driving roller shaft is driven by the hydraulic motor, the hydraulic motor drives the driving roller to drive the cylinder cover and the driven roller to rotate, and the distance between the two rollers can be adjusted by twisting the lead screw to correspond to cylinder covers with different diameters. 一种滚筒工装，属于机械加工领域，丝杠在支撑座上。丝杠有方向相反的螺纹，分别螺纹连接主动和从动滚筒支撑座。主动滚筒轴支撑在主动滚筒支撑座上。从动滚筒轴支撑在从动滚筒支撑座上。主动滚筒轴由液压马达带动，液压马达主动滚筒带动缸盖及从动滚筒旋转，扭动丝杠可以调节两个滚筒的距离，对应不同直径的缸盖。
