PURPOSE:To slightly move and fix a heavy weight work easily by providing a disk body mounting a ball and a hydraulic jack maving the dish body up and down in a work turning device horizontally aligning and fixing the work to turn it. CONSTITUTION:The axial hole of a work 14 is loosely coupled with an expanded inner diameter chuck unit, and the work is mounted on multiple master levels 17 arranged at the same distance on the circular periphery. A hydraulic jack 21 is operated to raise a dish body 26 mounting a ball 25 so that the work 14 is slightly removed from the upper edge of the master level 17 while being supported by the ball 25. The claw of the chuck unit is expanded and the work 14 is slightly moved and aligned in the horizontal direction. After aligning, the hydraulic jack 21 is operated ot lower the dish body 26 so as to fix the work to the chuck unit. |
