Abstract

PURPOSE:To make centering process of a thin cylinder simply and without any strain on the cylinder, by interposing screw feeding devices respectively between three or more inside chucks touching the inner peripheral surface of the captioned cylinder and transferring the chucks radially at the same speed. CONSTITUTION:When any one of feeding screws 5 turns, other feeding screws 5 also turn at the same time through gears 3, 4. Then, three inside chucks 10 arranged on jigs 8 move simultaneously forward or backward radially by the same distance. When the inside chucks 10 touch the inner periphery of a workpiece 9 during this process, the fixed shaft 2 on the center of a table 1 and the center of the workpiece 9 coincide with each other, and then, centering is performed exactly. Next, when outside chuck feeding screws 12... are turned respectively, outside chucks 13 engaged with them move along its axis without turning, and the chucks 13 push the outer periphery of workpiece 9. Thereby, any strain does not occur on the workpiece.
