Claims

[Scope of utility model registration request]

A chuck body is fastened concentrically with the main shaft rotatably supported on the headstock and has a collet expansion action surface, and the chuck body is inserted and fixed to the outer circumference of the main shaft and has an outer diameter smaller than the outer diameter of the piston ring, and has an outer diameter that is smaller than the outer diameter of the piston ring. The positioning cylinder is inserted into the main shaft and the center of the chuck body, and is fixed to the scolding end that is moved in the axial direction by fluid pressure. A fastening piece having an action surface is interposed between the expansion action surface of the piece and the expansion action surface of the chuck body, and normally when the outer diameter of the collar is expanded to a smaller diameter than the inner diameter of the piston ring, the end face of the collar is A flanged collet that clamps the piston ring between the end face of the positioning tube, and a collet that is supported by the headstock so as to be movable in the spindle axis direction, and that is configured to have an outer diameter when machining the piston ring concentrically with the axis of the chuck body. A chuck guide is provided with a hole to determine the mounting/removal position of the piston ring, and is moved to a retracted position on the spindle side from that position, and a seat that grips the piston ring on the chuck-facing surface on the chuck axis while suppressing the piston ring from opening. A piston ring chuck device comprising: a button for pushing into a hole in the chuck guide.
