Slewing bearing rounding device

The invention discloses a slewing bearing rounding device. The device comprises a support, a positioning block, a supporting roller, an adjusting roller, an active supporting roller, a hydraulic jack,a clamping base and an adjustable displacement sensor; a slewing bearing to be detected is fixed among the positioning block, the supporting roller and the active supporting roller, the adjusting roller makes contact with an inner hole of the slewing bearing to be detected, and the rounding device is simple in structure, and convenient to use. The slewing bearing to be detected can rotate on thedevice, through the adjustable displacement sensor, the position required to be shaped is determined, the hydraulic jack is used for rounding, the shaping precision and shaping work efficiency of theslewing bearing are improved, labor intensity of a worker is reduced, the quality of the slewing bearing is improved, and the service life is prolonged. 本发明公布了一种回转支承整圆设备，包括支架、定位块、支撑滚轮、调节滚轮、主动支撑滚轮、液压千斤顶、卡座、可调节式位移传感器，待测回转支承固定在定位块
