Abstract

PURPOSE: To enable rapid accomodation of a device by a method wherein a V- shaped block for supporting a workpiece is divided into two pieces, each piece is constituted so as to be capable of moving in the directions opposite to each other by linking the same to the other with a rack and pinion mechanism and thereby a change of step is made unnecessary when the diameter of the workpiece is altered.
CONSTITUTION: A V-shaped block serving as a supporting block for a workpiece is constituted by a piece A6 with a titled surface 5 formed in the upper end thereof and by a piece B7 provided with a tilted surface 8 which forms the V-shaped block together with the tilted surface 5 of the piece A6. Both pieces 6 and 7 are geared with each other by racks 3 and 10 and a pinion 11 so that they can move in the directions opposite to each other. Accordingly, the piece A6 is lowered, while the piece B is projected, by the clockwise rotation of the pinion 11, whereby the V- shaped block is turned into a state fitted for receiving the workpiece of large diameter. On the contrary, by the counterclockwise rotation of the pinion, the block is turned into the state fitted for small diameter. In this way, no specific change of step becomes unrequired for the alteration of the diameter of the workpiece, whereby rapid accomodation of the device turns to be possible.
