Shaft coupling aligning device

The utility model provides a shaft coupling aligning device, including main shaft three -jaw holding frame, main shaft three -jaw holding frame includes the main shaft pole, adjusting nut fixes on the main shaft pole, the cover has fixed loop and slip -ring on the main shaft pole, fixed loop and main shaft pole fixed connection, slip -ring and main shaft pole sliding connection, the fixed loop is connected with three centre gripping movable claw through rotatory pair of activity, three centre gripping movable claw is connected with three mobile push rod through rotatory pair of activity respectively, mobile push rod is connected with the slip -ring through rotatory pair of activity, the main shaft pole is connected with the axial holding frame is perpendicular, the axial holding frame is connected with radially the holding frame is perpendicular, the axial holding frame, on the radial holding frame respectively the fixation clamp hold the axial and radially measure the percentage table survey, rotary main shaft three -jaw holding frame, make the axial and radially measure the contact of percentage table surface gyration a week along quilt survey shaft coupling, whether whether take place angular deflection through the percentage table judges according to the shaft coupling with concentric by the survey shaft coupling, measure fast and the accuracy height, the structure is highly universal.
